　　Flexible circuits, also known globally as flex circuits, flexible printed circuit boards, flex print, or flexi-circuits, are part of the electronic and interconnection family. They consist of a thin insulating polymer film with conductive circuit patterns affixed to it, usually coated with a thin polymer for protection.By comparison, it can be seen that RF PCB It has certain advantages and great cost performance. https://www.wellcircuits.com/

　　The technology has been used for interconnecting electronic devices since the 1950s and is now a crucial interconnection technology in many advanced electronic products today.

　　Size and Weight Reduction Benefits of Flexible Circuitry

　　Wiring solutions that fit where rigid boards cannot.

　　Thin, lightweight products that are durable.

　　Miniaturized versions of existing technologies.

　　Three-dimensional packaging geometry.

　　A low number of device interconnects.

　　Shock and vibration resistance.

　　These benefits highlight flexible circuitry as an ideal solution for mobile consumer electronics. Inside modern devices like smartphones and laptops, flexible circuitry plays a critical role.

　　In mobile devices, using rigid circuitry would result in devices that are too large, heavy, and fragile to carry conveniently, exemplified by the Osborne I, the first fully powered mobile computer, weighing an intimidating 24.5 pounds. Size and weight reduction is only part of the flexible circuit story; they are also ideal for high-temperature and high-density applications.

　　High Temperature and High-Density Applications

　　Flex circuits, often made of polyimide or similar polymers, dissipate heat better than most rigid circuit board materials. This feature allows flexible circuits to be placed in locations where heat would impact the performance of rigid circuit boards.

　　Flexible circuit boards can withstand extreme temperatures ranging from -200＜C to 400＜C, making them desirable for borehole measurements in the oil and gas industry and preferred in industrial sensor technologies for their small size and durability.

　　High temperature resistance, combined with chemical resistance, excellent resistance to radiation and UV exposure, and the ability to control impedances in high-density designs, makes flexible circuits highly beneficial for manufacturers.

　　Why Not Make All Circuit Boards Flexible?

　　Flexible circuit boards are certainly useful, but they are not going to replace rigid circuit boards for all applications. Cost efficiency is the main obstacle to implementing an exclusively flexible circuit board design in a consumer product. Rigid circuit boards are less expensive to manufacture and install in a typical automated high-volume fabricating facility.

　　Typically, the ideal solution for an innovative product is one that incorporates flexible circuitry when necessary, and employs solid, reliable rigid circuit boards where possible to keep manufacturing and assembly costs down.

　　With the development of society and the improvement of people’s living conditions, air conditioning has become a necessity in people’s lives. But you know what? The placement of air conditioners is also said to be feng shui. The improper placement of air conditioners will actually block the wealth of the family. So how to place the air conditioner? What are the precautions for air conditioning placement? Let’s take a look.Under people’s attention commercial hvac systems Finally grow into what people need, born for the market and come for the demand. https://puremind.com/product-category/puremind-air-conditioner/commercial-air-conditioner/

　　Air conditioning is a typical product of modern houses, and there is no introduction about air conditioning in any ancient geomantic books. However, air conditioning has obvious influence on the geomantic omen of Yangzhai because of its function of air supply and temperature regulation. So, are there some feng shui precautions for air conditioning, a household appliance that only appeared in modern houses? Let’s sum up some questions about air conditioning feng shui.

　　1. The air outlet of the air conditioner should not face the door.

　　It has been mentioned many times that “storing wind and gathering gas” is the basic principle of Feng Shui. One of the major characteristics of air conditioners is that they can spray air to adjust the indoor temperature. These spouted air currents themselves cause direct disturbance to the gas field of the house. The gas field is too strong, and the air flow and the air flow entering the gate will have an impact, which will directly destroy the stability of the gas field of the house. Not to mention gathering wealth, the popularity will be washed away by the gas field of the house.

　　2. Don’t hang the air conditioner on the sofa or bedside.

　　The wall-mounted air conditioner itself is particularly similar to the beam in shape. As we all know, there can’t be a cross beam above the sofa or bedside, otherwise there will be a problem of the cross beam topping. In fact, air conditioners should also avoid the situation of topping. Moreover, the air conditioner itself has cold air injection, which goes straight to the head or body, and the impact is more direct. Therefore, remind everyone that when choosing the hanging position of air conditioner, try to avoid pressing against people’s body parts.

　　Don’t blow the air conditioner directly on people.

　　In the first article, we emphasize that air conditioning can’t blow on people’s heads, which is mainly from the perspective of air conditioning topping. In fact, even other parts of the body, try not to be blown directly by the air conditioner. Although the air conditioner is cool, it is very easy to catch a cold, stroke or backache, which directly affects people’s health. You can manually change the air outlet direction of the air conditioner to avoid being directly blown.

　　4. Air conditioner should not blow the dining table directly.

　　Experienced friends know that long-term use of air conditioners will absorb a lot of dust and germs. Therefore, for air conditioners that are often used, if the filter screen cannot be cleaned on time, it will also cause the accumulation of foul air in the house. If the air conditioner blows air directly on the dining table, these foul gases and germs can easily be directly adsorbed on our food, which will have an unnecessary impact on our health.

　　5. Don’t blow the air conditioner directly.

　　Some friends will install air conditioning in the kitchen because of the large space in the kitchen. But when installing air conditioning in the kitchen, don’t put the air conditioner directly on the stove mouth, especially on the flame. The reason is very simple. This kind of direct gas field disturbance will not only make the flame unstable and cause safety hazards, but also symbolize the hostess in the image. The direct air conditioning will also have unnecessary effects on the hostess’s own body. So remind everyone, if you have to install air conditioning in the kitchen, don’t let the air conditioning mouth directly face the stove mouth.

　　Location of air conditioner

　　Fans must not be placed in the financial position.

　　If the air conditioner happens to be in the financial position, it will blow away your fortune. The financial position pays attention to hiding the wind and gathering gas, and should be quiet and not moving. They are also fast-running appliances, so they will transfer the airflow from the outside to the home, and plants, fish and the like should be used to stimulate the financial position. Fans can only blow away wealth, which is very unfavorable to home wealth and will soon appear. Therefore, we must pay attention to the fact that the fan must not be placed in the financial position.

　　The fan must not be placed in a fierce position.

　　But the fan is a dynamic substance, which is basically a product of making brake gas. Especially when it is placed in a fierce position, it will provoke fierceness, which is really bad.

　　The cold air that doesn’t start is not enough for feng shui effect.

　　Air-conditioning emits cold and frozen gas, so it belongs to gold in the five elements, which is the same as refrigerator. If the summer is long and the opening time is more than half a year or more, air conditioning will have a great influence on home feng shui, but it should be noted that the air conditioning that is not started is basically not enough to achieve feng shui effect.

　　They belong to gold, and the way to find out where to put them is very simple. Whoever wants gold from a family member, putting air conditioning in the position where the member belongs is the most favorable feng shui decoration. If the father wants gold, put it in the northwest, if the mother wants gold, put it in the southwest. The wind released by the air conditioner will create a geomantic magnetic field. Adjusting the tuyere to the upper side is more beneficial to home feng shui, because in the wind direction, it represents the airflow swirling down from the ceiling and the airflow blowing, which is the best form.

　　Its decoration should be based on the needs of the five elements of family members, and can also be used in conjunction with the lucky time of the year. Find out the bad side and the financial side. If the air conditioner is located in the bad side, the air conditioner on this side should be turned on as little as possible, and feng shui objects should be placed to release two black and five yellow.

　　kitchen

　　The kitchen stove is where the whole family can fill their stomachs. If the air conditioner is directly on the stove fire, it will make the stove fire weak, which will damage the energy of the food in cooking, thus affecting the health of the housing people. In addition, the stove fire is also representative, so it has a great impact on the life of couples.

　　Correction method

　　Don’t install air conditioner if you can, but if you must, blow the wind towards the ceiling or sideways as much as possible.

　　dining room

　　When air conditioners are used for a period of time, dust will inevitably accumulate. Therefore, if the air conditioners in the dining room blow directly on the dining table, it is very likely that the dust will fall into the hot food with the wind, and of course, it is easier to cool the delicious meals on the table. Therefore, it is best not to place the air conditioners in the dining room above or near the dining table.

　　bedroom

　　When people sleep, the sweat pores are wide open and the respiratory system is relatively unguarded. Therefore, if the air conditioner blows directly, it will not only make people feel unwell and catch a cold, but also attract evil spirits more easily.

　　Correction method

　　Raise the air outlet upward, or slightly open the window in the room to evenly blow the cold air.

　　study

　　Air conditioning makes people cool, so it has the function of condensing thinking and improving reading concentration. If we can move the air conditioner in the study to the north and use the energy of air conditioning operation, it will drive Wenchang to good luck, which will certainly benefit candidates or people who study knowledge. Of course, remember not to blow the air outlet toward your face or head, lest your head be unbearable before you finish reading the book.

　　sitting room

　　Air-conditioning is a fast-running electrical appliance, so it will turn the outside air flow into the home, and the southwest of the Year of the Monkey will treat diseases. Therefore, if the air-conditioning at home is placed in this position, it will definitely make the family suffer from illness and illness this year.

　　Correction method

　　Use a small fan to change the wind direction opposite the air conditioner. In addition, in the Year of the Dog, peach blossoms dominate the northeast, Wenchang dominates the west, and the northwest dominates the financial position. If you want to strengthen the above fortune, you can also move the air conditioner to this position, which has a strong effect on luck and transshipment.

　　Popularization of feng shui knowledge of air conditioning

　　Nowadays, people’s living conditions are improving day by day, and the popularization of air conditioning has extended to every household. Air conditioning is warm in winter and cool in summer, which not only improves people’s quality of life, but also brings more warmth and comfort to people. Then, from the perspective of geomantic omen, how to make the layout of air conditioners more in line with the principles of geomantic omen, so as to prosper in people’s career, wealth, marriage and health, and improve people’s quality of life?

　　First, the current three types of home air conditioning

　　At present, home air conditioners can be generally divided into wall-mounted air conditioners, cabinet air conditioners and central air conditioners. According to the principles of geomantic omen that “there is evil spirit when visible” and “there is an image that should respond”, it is considered that there are obvious differences between the “existing form” and “supply cooling and heating mode” of these three types of air conditioners in home, so their functions and functions in home geomantic omen will be different. That is to say, different types of home air conditioning layout in the same location may have different feng shui consequences.

　　Second, the interpretation of three key locations of home air conditioning layout

　　1. Is air conditioning suitable for financial position?

　　It is believed that, first of all, cabinet air conditioners are not suitable for financial position. As we know, financial position is the place where the breath in the home gathers, and cabinet air conditioners will occupy the financial position because of its tall body, and then “squeeze” the wealth; Secondly, central air-conditioning is not suitable for the financial position. Generally speaking, the wind of central air-conditioning blows vertically downward, while the financial position in geomantic omen is generally quiet and motionless. If central air-conditioning is installed above the financial position, its airflow will blow straight down, and the financial position will be exhausted, which is actually an image of money not gathering; Finally, it is considered that the wall-mounted air conditioner is very suitable for the financial position, because it just overcomes the shortcomings of the cabinet air conditioner, which is too large and the air flow in the central space is straight down. Moreover, the wall-mounted air conditioner also has the advantages of high and basic lateral air exhaust. Although it is in the financial position, its air flow is discharged straight ahead, so that while strengthening the air flow in the house, it also maintains the relatively stable and gentle replacement of the air in the financial position, and then uses the air in the financial position to keep fresh.

　　2. Is the air conditioner suitable for Wenchang?

　　It is believed that, generally speaking, all three types of home air conditioners are suitable for layout in Wenchang. Because Wenchang represents school, career, official transport, fame, reputation and influence in geomantic numerology, the layout of home air conditioners in Wenchang will definitely enhance the corresponding energy, and then play the role of prosperity. Then, why can the layout of home air conditioning improve the corresponding energy in Wenchang? Because Wenchang’s general five elements attribute is fire, which is often said to be the main fire. The bright wood fire is the most prosperous image in geomantic numerology, while the five elements of air conditioning discharged from air conditioning are aquatic wood, and the five elements of heating discharged are wood fire, while heating is generally used in winter, and water is also used in winter. Therefore, this forms the image of aquatic wood and wood fire, and its breath gathers in fire, which means Wen and Wenchang; Even more, because of the existence of water, the situation of fire flourishing and wood burning will never be formed, which is also the principle of the five elements of “one (water) four (wood) and the palace master Wang Wen” in Xuankong Feng Shui.

　　3. Is the air conditioner suitable for layout at Taiji point?

　　Taiji point is the center of gravity and center point in the home. It is considered that among the three types of home air conditioners, the central air conditioner is the most suitable layout in Taiji. The central air conditioning is arranged at Taiji point. In the cold winter, warm air comes from the sky, which makes the whole home full of warmth. In the hot summer, the cold wind falls from the “sky”, making the whole home full of sweetness and coolness. As we know, geomantic omen pays attention to the word “image”, and this image is the image of enjoying the grace of heaven and meeting your career. However, wall-mounted air conditioners and cabinet air conditioners are difficult to “hide” and are limited by installation conditions, drainage conditions and other factors, so it is really difficult to achieve the feng shui effect of central air conditioners.

　　Third, the basic feng shui knowledge of home air conditioning layout

　　Warm reminder

　　In the layout of home air-conditioning, the direction of its air outlet is particularly important. Generally speaking, the air outlet of home air-conditioning should not face the places where people are active frequently, mainly the “three places” such as seats, beds and stoves. This is the problem of different effects produced by “actively receiving feng shui energy” and “passively receiving feng shui energy” in the geomantic omen of the Ark. That is to say, when the air outlet of the air conditioner is facing the “three places”, people can only passively receive the feng shui energy, and when the feng shui energy exceeds a “degree” that people can bear, it will naturally do harm to people; However, when the air-conditioning geomantic omen is not directly opposite to the “three positions”, people can fully play their active role by actively receiving the geomantic omen energy, and generally there will be no harm caused by receiving the geomantic omen energy too much.

　　It’s getting hot, and it’s time to turn on the air conditioner. But can you really use air conditioning? Is it only cooling in summer and heating in winter? Air-conditioning remote controllers are generally equipped with a variety of use modes, and different modes have different use effects. Let’s take a look at it.More importantly, put Puremind Industrial Chillers It is imperative for us to make thorough analysis and maximize its social function. https://puremind.com/

　　Cool feeling mode

　　Applicable people: afraid of heat and cold.

　　Blowing the air conditioner in summer is cool, because the room temperature is lowered, and because the cold air blown by the air conditioner blows on the body, it plays the role of an electric fan.

　　The principle of the “cool feeling” function is simple: control the angle and speed of the air outlet to prevent the air conditioner from blowing at people-the traditional way is to adjust the angle of the air deflector and the speed of the fan, and the new air conditioner is even equipped with an infrared probe to prevent the wind from blowing directly at people, which is very friendly to people who are afraid of cold stars.

　　Air supply mode

　　Applicable scenario: when it is not too hot

　　Air conditioning is a combination of “cooling/heating+fan”, and the “air supply” function is to turn on the fan instead of starting the compressor, electric heating wire and other temperature-related components of the air conditioning.

　　If you want to improve the air quality, breathe and smell, you need air conditioning with fresh air system.

　　Eco mode

　　Applicable scene: before going to sleep

　　”eco”, the abbreviation of economic, is also called “energy saving” mode.

　　It is suggested that the air conditioner can be changed to this mode before going to bed. When you fall asleep at a comfortable room temperature, the air conditioner will change the temperature, increasing it in summer and decreasing it in winter. In short, it will reduce the power consumption until it is completely turned off, that is, the “sleep” mode.

　　Dehumidification mode

　　Applicable scene: hot and humid weather

　　Both “dehumidification” and “refrigeration” modes will produce refrigeration effect. The difference is that after the “dehumidification” mode is turned on, the air conditioner will appropriately cool the indoor air, let the water vapor condense into water, and then discharge it to the outside-reducing the indoor humidity, and people’s body temperature will be cooler. The main purpose of the “refrigeration” mode is to reduce the indoor temperature, and the water vapor in the condensed air is an incidental effect.

　　From the effect point of view, after opening the “dehumidification” mode, although the air conditioning temperature is not very low and it does not consume too much electricity, it will be more comfortable.

　　It should be noted that this function is only effective in areas with humid climate. If you live in a dry area, this function is not recommended.

　　Automatic mode

　　Applicable people: people who need indoor constant temperature and people who use company air conditioning.

　　To choose this mode, you need to set a temperature first, say 26 degrees Celsius. If the room temperature is lower than 26 degrees Celsius, the air conditioner will start heating; If the room temperature is higher than 26 degrees Celsius, the air conditioner will start to cool.

　　Auxiliary heating mode

　　Applicable scene: when you just enter the house in winter and are about to be frozen.

　　There are two ways to heat by air conditioning. One is a porter who relies on heat-compressor. From the thermodynamic point of view, using compression mechanism to save heat and electricity, but the heating speed is slow, and when it is particularly cold outdoors, such as below 0 degrees Celsius, the heating efficiency will become low.

　　The other is the producer of heat-electric heating wire. “Auxiliary heating” is the option of turning on the electric heating wire, which can assist the compressor to achieve the effect of rapid heating. After the room temperature reaches the set temperature, just keep the temperature by the compression mechanism. At this time, the “auxiliary heating” function can be turned off in order to save electricity.

　　Everyone can use these functions as much as possible. After all, we spent thousands of dollars to buy an air conditioner, and if we don’t drain all its functions, we will lose money!

Zagreb, March 15. Croatian President Milanovic announced on social media on the 15th that he will participate in the Croatian parliamentary elections to be held on April 17 as an independent candidate from the Croatian Social Democratic Party and will run for the position of Prime Minister.

Milanovic said he was full of confidence in winning the election and would resign as president after winning the election and assume the responsibility of leading the Croatian government. Until then, he will continue to perform his duties as President of Croatia in accordance with the Constitution.

Milanovic’s announcement shocked Croatia, because there is no precedent for a president to run for prime minister in Croatian history. As a Social Democrat, Milanovic’s move will undoubtedly inspire the Social Democratic Party, which is currently at a disadvantage in the parliamentary elections, but it will also cause huge controversy. Croatian constitutional expert Baric told the media that the Croatian Constitutional Court should clearly tell Milanovic that he can only run for prime minister if he resigns as president.

According to the latest opinion poll, the ruling party, the Croatian Democratic Community, led by Croatian Prime Minister Prenkovic, ranks first with a support rate of 265%, and the Social Democratic Party ranks second with a support rate of 179%.

Milanovic was elected President of Croatia in January 2020. Previously, he served as Prime Minister of Croatia from December 2011 to January 2016. (Reporter Li Xuejun)

United Nations, July 16 (Reporter Wang Jiangang) Fu Cong, Chinese Permanent Representative to the United Nations, spoke at the Security Council’s open debate on international order and multilateral cooperation on the 16th, calling on the international community to promote the construction of a more just and reasonable international order, safeguard sovereign equality, and Let every country find its place in the multipolar system, play its due role, and jointly promote an equal and orderly world multipolarization.

Fu Cong said that countries should respect each other, take into account each other’s core interests and major concerns, respect the development paths and institutional models independently chosen by the people of all countries, and not interfere in other countries ‘internal affairs; create common security, be based on the objective law that security is indivisible, and adhere to Resolve disputes through dialogue, resolve differences through consultation, and build a more balanced, effective and sustainable security architecture; Promote common development, promote inclusive economic globalization, accelerate the implementation of the 2030 Agenda for Sustainable Development, and strive to achieve the goal of leaving no country or anyone behind.

Fu Cong called on all countries to uphold fairness and justice, safeguard the authority of the United Nations and international law, advocate a global governance concept of extensive consultation, joint contribution and shared benefits, enhance the representation and voice of developing countries; demonstrate openness and inclusiveness, promote equal dialogue, exchanges and mutual learning among different civilizations, promote mutual understanding among people of all countries, and promote common values for all mankind.

Fu Cong pointed out that the real intention of some countries in the so-called rules-based international order is to create an alternative system outside the existing international legal system and seek legitimacy for double standards and exceptionalism. There is only one order in the world, that is, an international order based on international law. There is only one set of rules, that is, the basic norms of international relations based on the purposes and principles of the United Nations Charter.

Fu Cong said that NATO, as a well-known regional military group left over from the Cold War, seeks to expand its sphere of influence, is keen to create false narratives, add fuel everywhere, incite camp confrontation, and even blame and blame domain name foreigners on the Ukraine issue. This runs counter to the international community’s efforts to promote peace and talks. History has fully proved that wherever NATO’s black hands extend, turmoil and chaos appear. China advises NATO and some countries to reflect on themselves and stop being troublemakers who harm others and undermine common security.

Fu Cong said that common development and common security complement each other and are the foundation of a good international order, in which development is the overall key to solving all problems. Some countries generalize the concept of national security, build small courtyards and high walls, impose indiscriminate unilateral sanctions, and disrupt the global production and supply chain, which will ultimately lead to a situation of double lose and multiple lose. The international community must resolutely resist this erroneous practice.

Fu Cong said that Chinese leaders followed the trend of the times and proposed the Five Principles of Peaceful Coexistence, which fully reflected the spirit of the Charter and created the basic norms of international relations that countries, big or small, strong or weak, regardless of East and West, should respect each other and treat each other as equals., also provides an important ideological foundation for promoting the development of the international order in a more just and reasonable direction. Chinese leaders ‘proposal to build a community with a shared future for mankind is an inheritance and promotion of the purposes and principles of the United Nations Charter and the Five Principles of Peaceful Coexistence under the new situation.

　　Improper use of air conditioningcontemporaneity Puremind Split Air Conditioners Our competitors have not made large-scale improvements, so we should get ahead of everyone in the project. https://puremind.com/

　　Not only will it increase electricity consumption,

　　It may even affect your health.

　　Today, follow the Shanghai Health Promotion Center.

　　Let’s learn the “cold knowledge” of air conditioning use ~

　　Don’t “open and close for a while”

　　I wonder if you have had such an experience?

　　Caught in the strange circle of air conditioning turning on cold and turning off hot, repeated operation is always “cutting suitable”; Or go out and get a courier, thinking that it is more energy-saving to turn off the air conditioner first.

　　In fact, often this behavior of frequently starting the air conditioner increases the power consumption and is not conducive to the maintenance of the air conditioner.

　　Studies have proved that air conditioning “turns on and off for a while” does not actually save electricity. Therefore, if you only go out for a short time, you don’t have to turn off the air conditioner and turn it on again.

　　Pay attention to “humidity” and “temperature”

　　The muggy air has a high humidity, so it is uncomfortable to adjust the temperature. At this time, try to turn on the “dehumidification mode” after air conditioning refrigeration, and the air will become more refreshing and comfortable.

　　If you need to stay in an air-conditioned room for a long time, remember to drink water properly to avoid the loss of water.

　　Practice has proved that it is most appropriate to control the indoor and outdoor temperature difference at 6-8≧, mainly to reduce the burden on the thermoregulation center and avoid the symptoms of dizziness, headache and dry skin and mucosa. Therefore, the air conditioning temperature is set at 26 to 28≧.

　　Don’t sweat and rush into the air-conditioned room.

　　In hot summer, it is easy to sweat when you move a little and bask in the sun. Do you just want to rush into the air-conditioned room? At this time, you should be careful that the disease will come to you.

　　For the general population, sudden cold and heat are easy to catch a cold, have a fever and have diarrhea; It is even more dangerous for patients with hypertension and coronary heart disease.

　　The cardiovascular system in the original thermal environment is in a state of relaxation, and the sudden cooling air after entering the air-conditioned room makes the blood vessels contract urgently, which is prone to dangerous situations such as myocardial infarction.

　　Therefore, don’t rush into the air-conditioned room after sweating, let the sweat collect first, or wipe your body with a dry towel first. When the air conditioner is just turned on, it should not be adjusted to a too low temperature, and at the same time, it should avoid cold air blowing directly on the head, neck and waist and abdomen.

　　Do a good job cleaning

　　The cleaning problem of air conditioning is often easily overlooked, and the bacteria hidden in it will take advantage of the opportunity to cause “air conditioning disease.”

　　Legionella, which lurks in the daily artificial water environment, is such a pathogen. Water contaminated by bacteria can be inhaled by human body in the form of aerosol. After people are infected with Legionella, there will be symptoms similar to pneumonia, such as high fever, chills, fatigue, muscle pain, etc., which may even be life-threatening.

　　The air conditioning system is the main “hiding point” of Legionella, so it is necessary to clean and disinfect the air conditioning; If it is a central air conditioner, the deposited cooling tower water should be replaced and the attached “dirty things” should be removed in time. Don’t forget to clean the casing and filter screen after the “air conditioning season”.

　　In addition, it is recommended to open the window for ventilation every 2-3 hours to ensure the cleanliness of indoor air.

From May 7 to 13, a COVID-19 variant named KP2 was spreading all over the world. In early May this year, the World Health Organization (WHO) listed the KP2 subvariety as a surveillance variant.

MVK, head of COVID-19 technology in World Health Organization (WHO), said that KP2 is a descendant pedigree of JN1, while JN1 is the main strain in the world, and KP2 spike protein has an extra mutation. There are other emerging variants, JN1 continues to evolve, and we will continue to closely monitor the evolution of the virus.

According to the latest “epidemic situation of novel coronavirus infection in China in April 2023” released by the Chinese Centers for Disease Control and Prevention, no two mutants have been found in China. The report shows that from April 1 to April 30, 2024, 31 provinces (autonomous regions, municipalities directly under the Central Government) and Xinjiang production and Construction Corps reported a total of 11299 local cases of novel coronavirus genome effective sequences, all of which were Omicron mutants. The main epidemic strains were JN1 series variants, and the top three were JN1, JN14 and JN116.

On May 13, Zhao Wei, director of the Biosafety Research Center of the School of Public Health of Southern Medical University, told People’s Daily Health client reporter that considering that the infected people already had certain antibody levels and immune barriers, even if there were new mutants, the symptoms of the current variants are still mainly mild and asymptomatic infections. In addition, the emergence of new mutants indicates that novel coronavirus has not disappeared, and the virus is still mutating. from a clinical point of view, although the current mutants have increased the advantage of transmission, there is no difference between the clinical symptoms of the infected person and the previous strains. At present, there is no significant increase in pathogenicity, and the serious disease rate should not increase.

According to the picture, “the epidemic situation of novel coronavirus infection in China in April 2023”.

The KP2 mutant is a derivative of JN1. There is a point mutation of two amino acids on the outermost spike protein, resulting in increased infectivity, which may be the main reason why it has quickly become the mainstream mutant. Internationally, it has surpassed JN1 to become the main epidemic strain in some countries. Therefore, many people are worried about triggering a new round of infection peak, but it needs to be clear that as long as the pathogenicity does not increase significantly. You don’t have to worry too much for the time being. Zhao Wei explained.

According to the reporter, globally, the KP2 mutant has begun to spread in many countries around the world. According to the data released by the Centers for Disease Control and Prevention (CDC) on May 10, a COVID-19 mutant named KP2 has replaced JN1 as the main epidemic strain in the United States. On May 9, local time, GN reported that KP2 quickly dominated Canada. As of April 28, national data showed that KP2 accounted for 266% of all COVID-19 cases in Canada, more than other JN1 subvariants.

From the clinical observation, this mutant is still as contagious as other O mutants, but its pathogenicity is weak. At this stage, the emergence of new variants of the virus will not have a significant impact on everyone’s normal life, but there may still be severe cases for the elderly and people with low immunity, so remind these high-risk people to continue to pay attention to the information released by the relevant departments and do a good job of personal protection during the epidemic. Zhao Wei warned that it is still possible for the virus to mutate in the future to produce strains with more transmission advantages, and even do not rule out the emergence of strains with strong virulence, and it is necessary to continuously monitor virus changes and develop safer and effective vaccines.

　　01Therefore, we should understand air conditioner solar power system Many benefits, absorb and summarize, and use them. https://puremind.com/product-category/puremind-air-conditioner/solar-air-conditioner/

　　If you leave home for a day …

　　Kureczka said: “If you just leave home for one day, it is more energy-saving to turn on the air conditioner, but you should raise the temperature by several degrees instead of keeping the comfortable temperature set at home.”

　　If the house is unoccupied for only a day or two, the same direction applies.

　　It’s not necessarily a bad thing to turn off the air conditioner during the day. Either way, the speed of the air conditioner is the same-it just takes longer to cool the hot space. In fact, if you drive at normal temperature all day, you may consume more energy than if you turn it off and have a meeting at night.

　　Air conditioning is not only to cool the space, but also to greatly reduce the humidity level. When the air conditioner is turned off for more than a few hours, the humidity level begins to rise, which may easily lead to mold growth, damage to electronic products, and warping and deformation of wood products. In addition, pets left at home may also be at risk of overheating and discomfort, which may occur especially in hot and humid climate.

　　This is why it is suggested to turn on the air conditioner, but turn up the temperature. The U.S. Department of Energy pointed out that higher indoor temperature will actually slow down the flow of heat into the house, thus saving energy and money.

　　When you get home, don’t turn the air conditioner down too low to “speed up” the cooling process, so that the room won’t get cold faster, and it will only increase energy consumption (cost money).

　　02

　　If you leave home for more than two days …

　　If the whole family (including pets) has been away from home for more than two days, the equipment can be turned off. Kureczka said, “Turn off the air conditioner, and you can save a lot of energy and bills.”

　　This means that when you come back, the temperature inside the room may not be very good and you will feel stuffy. Kureczka suggested, “Installing an intelligent thermostat is a good way to monitor and control the energy efficiency of your home, even if you are not at home-you can turn up the temperature before you leave and then turn it down on your way home.”

　　She also suggested that if you go out for more than a few hours, please close the curtains, which can effectively block the sun, so that the air conditioning unit does not have to work so hard. Especially in areas with extreme temperatures, this will make a huge difference.

　　03

　　At home …

　　The US Department of Energy and the Environmental Protection Agency suggest that the thermostat should be set to 26≧ or higher during the day, 28≧ when sleeping and 29≧ when going out.

　　Think this setting temperature is too high? When the temperature is reduced to 26≧, compared with 22≧, it can save 25% of the electricity bill.

　　Kureczka said: “It varies from person to person to adjust the temperature as high as possible while maintaining comfort. Generally speaking, increasing the temperature by 1 C will help reduce the cooling cost by 5%. “

　　If it is acceptable to adjust the temperature higher than you are used to, then other measures may also make you feel comfortable, such as using ceiling fans. But the ceiling fan will not change the temperature, so remember to turn off the electric fan when you leave the room. Otherwise, you have to pay unnecessary electricity bills.

　　Finally, try to ensure that the house is insulated, so that cold air will not escape and hot air will not sneak in.

According to a reporter from the head office, on May 22, local time, Norway and Spain respectively announced that they would formally recognize the Palestinian state on May 28. Ireland subsequently announced its formal recognition of the State of Palestine.

From mid-April to early May, Barbados, Jamaica, the Bahamas and other countries have announced the recognition of the State of Palestine. At this stage, nearly 150 countries have recognized the Palestinian State.

What does it mean that more and more countries recognize a Palestinian state?

Three European countries recognized the State of Palestine on the same day

Norwegian Prime Minister Stetler announced on May 22 that Norway will recognize a Palestinian state. Mr Stiller said the approval would take effect on May 28.

Subsequently, Spanish Prime Minister Sanchez announced that the country would recognize a Palestinian state on May 28. In addition, Irish Prime Minister Simon Harris also said that Ireland will formally recognize the Palestinian state.

Israel: recall Ambassador Palestine: welcome the decision of the three countries

After Norway and other three countries announced their recognition of the Palestinian state, Israeli Foreign Minister Katz immediately said that he would recall Israel’s ambassadors to Norway and Ireland. Katz said the move sent a clear message to Norway and Ireland that Israel would not remain silent.

It is reported that Israel has also recalled its ambassador to Spain, but the Israeli Foreign Ministry has not yet publicly confirmed the recall of the ambassador to Spain. Katz will also summon the ambassadors of the three European countries to Israel to condemn the three countries’ decision to recognize a Palestinian state. It is reported that Katz will show ambassadors a video of Israeli female soldiers being detained by Hamas militants.

Palestinian President Abbas issued a statement highly appreciating and welcoming the recognition of the Palestinian state by the three European countries on the same day. The statement said that the decision of the three countries is a salvation of the Palestinian-Israeli two-state solution, which urges all countries in the world to follow the example of Norway, Ireland and Spain to recognize the Palestinian state and support the realization of peace and stability on the basis of the two-state solution.

On the same day, the Palestinian Islamic Resistance Movement (Hamas) also issued a statement welcoming the initiative of the three European countries.

Recently, these countries have recognized the Palestinian state one after another.

On 19 April, Barbados announced its decision to formally recognize Palestine as a State.

On 22 April, the Ministry of Foreign Affairs of Jamaica issued a statement formally recognizing the State of Palestine.

On 2 May, Trinidad and Tobago decided at a cabinet meeting to formally recognize the State of Palestine.

On 7 May, the Ministry of Foreign Affairs of the Bahamas issued a statement that the Bahamas had decided to formally recognize the State of Palestine.

On May 10, the tenth emergency special session of the United Nations General Assembly adopted a resolution by a vote of 143 to 9, with 25 abstentions, determining that the State of Palestine was qualified as a member of the United Nations under the Charter of the United Nations and should be accepted as a member of the United Nations.

What does it mean for more and more countries to recognize a Palestinian state?

Qin Tian, Deputy Director of the Middle East Research Institute of the China Institute of Modern International Relations:

On 10 May, the tenth emergency special session of the United Nations General Assembly adopted a resolution by an overwhelming majority, affirming that the State of Palestine conforms to the membership of the United Nations as stipulated in the Charter of the United Nations and should be accepted as a member of the United Nations. This has put some pressure on some Western countries.

At the same time, Israel has stepped up its offensive against Rafah in southern Gaza, casting a shadow over the prospect of peace between Palestine and Israel. Under this pressure, countries that do not have too deep ties with Israel are the first to take the step of diplomatically recognizing a Palestinian state.

Although this is only the behavior of some countries, the impact is considerable, which exerts certain pressure on Israel, which is diplomatic and moral support beneficial to Palestine. It will also help the two sides to reach a Palestinian-Israeli peace settlement on a more equal basis in the future.

　　With the development of society and the improvement of people’s living conditions, air conditioning has become a necessity in people’s lives. But you know what? The placement of air conditioners is also said to be feng shui. The improper placement of air conditioners will actually block the wealth of the family. So how to place the air conditioner? What are the precautions for air conditioning placement? Let’s take a look.Industry experts have said that, solar heat and air conditioning It is very possible to develop and expand, which can be well seen from its previous data reports. https://puremind.com/product-category/puremind-air-conditioner/solar-air-conditioner/

　　Air conditioning is a typical product of modern houses, and there is no introduction about air conditioning in any ancient geomantic books. However, air conditioning has obvious influence on the geomantic omen of Yangzhai because of its function of air supply and temperature regulation. So, are there some feng shui precautions for air conditioning, a household appliance that only appeared in modern houses? Let’s sum up some questions about air conditioning feng shui.

　　1. The air outlet of the air conditioner should not face the door.

　　It has been mentioned many times that “storing wind and gathering gas” is the basic principle of Feng Shui. One of the major characteristics of air conditioners is that they can spray air to adjust the indoor temperature. These spouted air currents themselves cause direct disturbance to the gas field of the house. The gas field is too strong, and the air flow and the air flow entering the gate will have an impact, which will directly destroy the stability of the gas field of the house. Not to mention gathering wealth, the popularity will be washed away by the gas field of the house.

　　2. Don’t hang the air conditioner on the sofa or bedside.

　　The wall-mounted air conditioner itself is particularly similar to the beam in shape. As we all know, there can’t be a cross beam above the sofa or bedside, otherwise there will be a problem of the cross beam topping. In fact, air conditioners should also avoid the situation of topping. Moreover, the air conditioner itself has cold air injection, which goes straight to the head or body, and the impact is more direct. Therefore, remind everyone that when choosing the hanging position of air conditioner, try to avoid pressing against people’s body parts.

　　Don’t blow the air conditioner directly on people.

　　In the first article, we emphasize that air conditioning can’t blow on people’s heads, which is mainly from the perspective of air conditioning topping. In fact, even other parts of the body, try not to be blown directly by the air conditioner. Although the air conditioner is cool, it is very easy to catch a cold, stroke or backache, which directly affects people’s health. You can manually change the air outlet direction of the air conditioner to avoid being directly blown.

　　4. Air conditioner should not blow the dining table directly.

　　Experienced friends know that long-term use of air conditioners will absorb a lot of dust and germs. Therefore, for air conditioners that are often used, if the filter screen cannot be cleaned on time, it will also cause the accumulation of foul air in the house. If the air conditioner blows air directly on the dining table, these foul gases and germs can easily be directly adsorbed on our food, which will have an unnecessary impact on our health.

　　5. Don’t blow the air conditioner directly.

　　Some friends will install air conditioning in the kitchen because of the large space in the kitchen. But when installing air conditioning in the kitchen, don’t put the air conditioner directly on the stove mouth, especially on the flame. The reason is very simple. This kind of direct gas field disturbance will not only make the flame unstable and cause safety hazards, but also symbolize the hostess in the image. The direct air conditioning will also have unnecessary effects on the hostess’s own body. So remind everyone, if you have to install air conditioning in the kitchen, don’t let the air conditioning mouth directly face the stove mouth.

　　Location of air conditioner

　　Fans must not be placed in the financial position.

　　If the air conditioner happens to be in the financial position, it will blow away your fortune. The financial position pays attention to hiding the wind and gathering gas, and should be quiet and not moving. They are also fast-running appliances, so they will transfer the airflow from the outside to the home, and plants, fish and the like should be used to stimulate the financial position. Fans can only blow away wealth, which is very unfavorable to home wealth and will soon appear. Therefore, we must pay attention to the fact that the fan must not be placed in the financial position.

　　The fan must not be placed in a fierce position.

　　But the fan is a dynamic substance, which is basically a product of making brake gas. Especially when it is placed in a fierce position, it will provoke fierceness, which is really bad.

　　The cold air that doesn’t start is not enough for feng shui effect.

　　Air-conditioning emits cold and frozen gas, so it belongs to gold in the five elements, which is the same as refrigerator. If the summer is long and the opening time is more than half a year or more, air conditioning will have a great influence on home feng shui, but it should be noted that the air conditioning that is not started is basically not enough to achieve feng shui effect.

　　They belong to gold, and the way to find out where to put them is very simple. Whoever wants gold from a family member, putting air conditioning in the position where the member belongs is the most favorable feng shui decoration. If the father wants gold, put it in the northwest, if the mother wants gold, put it in the southwest. The wind released by the air conditioner will create a geomantic magnetic field. Adjusting the tuyere to the upper side is more beneficial to home feng shui, because in the wind direction, it represents the airflow swirling down from the ceiling and the airflow blowing, which is the best form.

　　Its decoration should be based on the needs of the five elements of family members, and can also be used in conjunction with the lucky time of the year. Find out the bad side and the financial side. If the air conditioner is located in the bad side, the air conditioner on this side should be turned on as little as possible, and feng shui objects should be placed to release two black and five yellow.

　　kitchen

　　The kitchen stove is where the whole family can fill their stomachs. If the air conditioner is directly on the stove fire, it will make the stove fire weak, which will damage the energy of the food in cooking, thus affecting the health of the housing people. In addition, the stove fire is also representative, so it has a great impact on the life of couples.

　　Correction method

　　Don’t install air conditioner if you can, but if you must, blow the wind towards the ceiling or sideways as much as possible.

　　dining room

　　When air conditioners are used for a period of time, dust will inevitably accumulate. Therefore, if the air conditioners in the dining room blow directly on the dining table, it is very likely that the dust will fall into the hot food with the wind, and of course, it is easier to cool the delicious meals on the table. Therefore, it is best not to place the air conditioners in the dining room above or near the dining table.

　　bedroom

　　When people sleep, the sweat pores are wide open and the respiratory system is relatively unguarded. Therefore, if the air conditioner blows directly, it will not only make people feel unwell and catch a cold, but also attract evil spirits more easily.

　　Correction method

　　Raise the air outlet upward, or slightly open the window in the room to evenly blow the cold air.

　　study

　　Air conditioning makes people cool, so it has the function of condensing thinking and improving reading concentration. If we can move the air conditioner in the study to the north and use the energy of air conditioning operation, it will drive Wenchang to good luck, which will certainly benefit candidates or people who study knowledge. Of course, remember not to blow the air outlet toward your face or head, lest your head be unbearable before you finish reading the book.

　　sitting room

　　Air-conditioning is a fast-running electrical appliance, so it will turn the outside air flow into the home, and the southwest of the Year of the Monkey will treat diseases. Therefore, if the air-conditioning at home is placed in this position, it will definitely make the family suffer from illness and illness this year.

　　Correction method

　　Use a small fan to change the wind direction opposite the air conditioner. In addition, in the Year of the Dog, peach blossoms dominate the northeast, Wenchang dominates the west, and the northwest dominates the financial position. If you want to strengthen the above fortune, you can also move the air conditioner to this position, which has a strong effect on luck and transshipment.

　　Popularization of feng shui knowledge of air conditioning

　　Nowadays, people’s living conditions are improving day by day, and the popularization of air conditioning has extended to every household. Air conditioning is warm in winter and cool in summer, which not only improves people’s quality of life, but also brings more warmth and comfort to people. Then, from the perspective of geomantic omen, how to make the layout of air conditioners more in line with the principles of geomantic omen, so as to prosper in people’s career, wealth, marriage and health, and improve people’s quality of life?

　　First, the current three types of home air conditioning

　　At present, home air conditioners can be generally divided into wall-mounted air conditioners, cabinet air conditioners and central air conditioners. According to the principles of geomantic omen that “there is evil spirit when visible” and “there is an image that should respond”, it is considered that there are obvious differences between the “existing form” and “supply cooling and heating mode” of these three types of air conditioners in home, so their functions and functions in home geomantic omen will be different. That is to say, different types of home air conditioning layout in the same location may have different feng shui consequences.

　　Second, the interpretation of three key locations of home air conditioning layout

　　1. Is air conditioning suitable for financial position?

　　It is believed that, first of all, cabinet air conditioners are not suitable for financial position. As we know, financial position is the place where the breath in the home gathers, and cabinet air conditioners will occupy the financial position because of its tall body, and then “squeeze” the wealth; Secondly, central air-conditioning is not suitable for the financial position. Generally speaking, the wind of central air-conditioning blows vertically downward, while the financial position in geomantic omen is generally quiet and motionless. If central air-conditioning is installed above the financial position, its airflow will blow straight down, and the financial position will be exhausted, which is actually an image of money not gathering; Finally, it is considered that the wall-mounted air conditioner is very suitable for the financial position, because it just overcomes the shortcomings of the cabinet air conditioner, which is too large and the air flow in the central space is straight down. Moreover, the wall-mounted air conditioner also has the advantages of high and basic lateral air exhaust. Although it is in the financial position, its air flow is discharged straight ahead, so that while strengthening the air flow in the house, it also maintains the relatively stable and gentle replacement of the air in the financial position, and then uses the air in the financial position to keep fresh.

　　2. Is the air conditioner suitable for Wenchang?

　　It is believed that, generally speaking, all three types of home air conditioners are suitable for layout in Wenchang. Because Wenchang represents school, career, official transport, fame, reputation and influence in geomantic numerology, the layout of home air conditioners in Wenchang will definitely enhance the corresponding energy, and then play the role of prosperity. Then, why can the layout of home air conditioning improve the corresponding energy in Wenchang? Because Wenchang’s general five elements attribute is fire, which is often said to be the main fire. The bright wood fire is the most prosperous image in geomantic numerology, while the five elements of air conditioning discharged from air conditioning are aquatic wood, and the five elements of heating discharged are wood fire, while heating is generally used in winter, and water is also used in winter. Therefore, this forms the image of aquatic wood and wood fire, and its breath gathers in fire, which means Wen and Wenchang; Even more, because of the existence of water, the situation of fire flourishing and wood burning will never be formed, which is also the principle of the five elements of “one (water) four (wood) and the palace master Wang Wen” in Xuankong Feng Shui.

　　3. Is the air conditioner suitable for layout at Taiji point?

　　Taiji point is the center of gravity and center point in the home. It is considered that among the three types of home air conditioners, the central air conditioner is the most suitable layout in Taiji. The central air conditioning is arranged at Taiji point. In the cold winter, warm air comes from the sky, which makes the whole home full of warmth. In the hot summer, the cold wind falls from the “sky”, making the whole home full of sweetness and coolness. As we know, geomantic omen pays attention to the word “image”, and this image is the image of enjoying the grace of heaven and meeting your career. However, wall-mounted air conditioners and cabinet air conditioners are difficult to “hide” and are limited by installation conditions, drainage conditions and other factors, so it is really difficult to achieve the feng shui effect of central air conditioners.

　　Third, the basic feng shui knowledge of home air conditioning layout

　　Warm reminder

　　In the layout of home air-conditioning, the direction of its air outlet is particularly important. Generally speaking, the air outlet of home air-conditioning should not face the places where people are active frequently, mainly the “three places” such as seats, beds and stoves. This is the problem of different effects produced by “actively receiving feng shui energy” and “passively receiving feng shui energy” in the geomantic omen of the Ark. That is to say, when the air outlet of the air conditioner is facing the “three places”, people can only passively receive the feng shui energy, and when the feng shui energy exceeds a “degree” that people can bear, it will naturally do harm to people; However, when the air-conditioning geomantic omen is not directly opposite to the “three positions”, people can fully play their active role by actively receiving the geomantic omen energy, and generally there will be no harm caused by receiving the geomantic omen energy too much.
