Air conditioning 26℃ is the most reliable Should I turn off the air conditioner when

  01On the other hand, commercial ac unit It also brings tangible benefits to everyone and feels useful. It is a model of the industry. https://puremind.com/product-category/puremind-air-conditioner/commercial-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.

The Chinese Embassy in Japan reminds Chinese citizens in Japan to guard against _minor crimes_

Today, people are interested in cnc machining services There are also many dependencies, and the expectations for products are getting higher and higher. https://www.ultirapid.com/services/cnc-machining/

On May 22, the Chinese Embassy in Japan issued a document reminding Chinese citizens in Japan to guard against minor crimes.

Japan implemented the “Minor Offences Law” in 1948, which stipulates clear penalties for 33 seemingly minor acts but may have adverse effects on public order. Some foreign tourists have been punished for not understanding the relevant laws. The Chinese Embassy in Japan summarized the behaviors that were easily ignored and reminded Chinese citizens in Japan and tourists coming to Japan to take precautions.

1. Unauthorized sneaking into unguarded houses, buildings or ships, or entering prohibited places, other people’s fields, disaster or crime scenes without authorization.

2. Carry without authorization knives, iron bars and other instruments that can harm others or tools that can be used to invade other people’s homes.

3. Refusing to obey the instructions of public officials or rescue personnel in special circumstances such as earthquakes, fires, and traffic accidents.

4. Make a fire in flammable places such as forests or near flammable materials such as gasoline.

5. Post advertisements and notices in other people’s homes without authorization, or remove or deface other people’s logos at will.

6. Declaring that he holds public office, title, degree at home and abroad, or wears legal uniforms or similar clothing that is incompatible with his identity.

7. Playing pranks at public or private ceremonies and hindering the ceremony.

8. Make noise that hinders others and refuse to correct it. Obstructing others from walking normally, or stalking others is disturbing.

9. Jumping in line in public places, being rude in words and deeds, spitting everywhere, and turning off sign lights or street lights for no reason.

10. Throw away garbage and waste at will.

All of the above acts are suspected of violating the “Minor Offences Law” and may be subject to fines, detention and other penalties. Chinese citizens in Japan are requested to abide by Chinese and Japanese laws, respect local religious beliefs and customs, and protect themselves. In case of emergency, report the case to the Japanese police in a timely manner and contact the embassy or consulate in Japan for help.

The air conditioner at home is easy to blow away the wealth.

  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.To some extent, industrial water chiller Our development has surpassed many peer businesses, but it has never stopped moving forward. https://puremind.com/product-category/puremind-air-conditioner/industrial-chiller/

  

  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.

Russia and Uzbekistan each hand over 95 detained military personnel to each other

In some cases, cnc machining services The advantages will become more and more obvious, and it will be able to develop indomitable after market tests. https://www.ultirapid.com/services/cnc-machining/

Moscow, July 17 (Reporter Jiang Youlin) The Russian Ministry of Defense announced on the 17th that Russia and Ukraine each handed over 95 detainees to each other that day.

The Russian Defense Ministry said on social media that after negotiations, 95 detained Russian personnel returned from Uzbekistan-controlled areas. In exchange, Russia handed over 95 Ukrainian military personnel to Uzbekistan. The released Russian personnel will be sent to Moscow for treatment.

Ukraine President Zelensky also posted on social media on the 17th that 95 detained Ukrainian military personnel were released from Russia that day.

Since March 2022, Russia and Uzbekistan have exchanged detained persons many times. According to the latest data provided by Uzbekistan’s department responsible for coordinating detained persons, a total of 3405 people have been released so far. (Participating reporter: Li Dongxu)

Basic knowledge of refrigeration and air conditioning is a must for beginners ~

  There are many kinds of refrigeration methods, such as gas expansion refrigeration, liquid gasification refrigeration, vortex tube refrigeration and thermoelectric refrigeration. Among them, liquid gasification refrigeration is the most widely used, and its working principle is to realize refrigeration by using the heat absorption of liquid gasification.Therefore, 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/

  

  1, the working principle of air conditioning (mainly refrigeration, heating on the contrary):

  

  The high-temperature and high-pressure refrigerant discharged from the compressor flows through the outdoor heat exchanger through the four-way valve, and dissipates heat to the outdoor air through heating transfer, and the refrigerant changes from gaseous state to liquid state-throttles and depressurizes through capillary (or solenoid valve)-one-way valve-filter-two-way valve (outdoor high-pressure pipe)-enters the indoor heat exchanger to absorb heat (realize refrigeration)-outdoor three-way valve (outdoor low-pressure pipe). Complete a single-loop refrigeration cycle.

  

  2. Types of components in refrigeration system:

  

  The air conditioning refrigeration system is mainly composed of four parts and some auxiliary equipment in the refrigeration system.

  

  The four major pieces are:

  

  compressor

  

  condenser

  

  Throttle mechanism

  

  Evaporator composition.

  

  Auxiliary equipment:

  

  Oil separator;

  

  Drying filter;

  

  Liquid storage tank;

  

  Electromagnetic four-way reversing valve;

  

  Solenoid valve; Check valve

  

  3, the working principle of each component

  

  Compressor: As the “heart” of refrigeration system, it has an important influence on the performance, noise, energy consumption, vibration and service life of air conditioning. According to the principle of thermodynamics, it can be divided into volumetric type and velocity type.

  

  Volumetric type: a certain volume of gas is sucked into the cylinder and the internal volume of the cylinder is changed to realize gas compression and forced discharge.

  

  Speed type: make the inhaled gas get a certain speed, and then slow down, so that kinetic energy can be converted into pressure energy and then discharged. The growth of gas is converted from speed.

  

  one

  

  Scroll compressor: It is formed by meshing two vortexes of stator and rotor.

  

  Rotor compressor: it consists of spindle with eccentric wheel, cylinder, sleeve, air inlet, slide plate, spring, exhaust valve and exhaust port.

  

  Condenser: The condenser transfers the refrigerating capacity of the evaporator in the refrigeration system to the environmental medium (cooling water or air) together with the power consumption of the compressor. According to cooling, it can be divided into air-cooled type, water-cooled type and evaporative type. When cooling, it mainly radiates heat to the outside, and when heating, it absorbs heat to the outside.

  

  Evaporator: The main function of the evaporator is to boil and evaporate the low-temperature and low-pressure refrigerant liquid that has entered the throttle in the evaporator, absorb the heat of the cooled medium, and then become low-pressure saturated (usually overheated) vapor itself, which is continuously sucked away by the compressor. In other words, the evaporator is a heat exchange device that absorbs heat (that is, outputs cold energy).

  

  Throttle element: Throttle element is one of the four main elements in the refrigeration system. Its main function is to throttle and reduce the pressure of high-pressure liquid refrigerant, ensure the pressure difference between condenser and evaporator, and make the refrigerant entering the evaporator absorb heat and evaporate at the required low pressure, thus achieving the purpose of refrigeration and cooling. Adjust the refrigerant flow into the evaporator to adapt to the load change of the evaporator and make the system run normally.

  

  Capillary: It is a very thin tube, usually with an inner diameter of 0.5 ~ 2.5 mm and a length of 1 ~ 5 m.. When the refrigerant flows in the tube, it is necessary to overcome the resistance in the tube, which naturally produces a certain pressure drop.

  

  Capillary characteristics: Because it is in the normally open state, when the compressor stops, the high and low pressure can be quickly balanced, which is conducive to the compressor starting again. Simple structure, convenient manufacture and low price. For the heat pump system, there is no import and export problem in the throttling process of refrigerant in capillary [this article source: refrigeration encyclopedia WeChat official account” target=_blank>. Using capillary refrigeration system, the performance of the unit is very sensitive to the refrigerant charge. When the operating conditions of the refrigeration system change, the capillary tube has poor ability to adjust the refrigerant flow. Due to the small inner diameter of capillary and long pipeline, it is easy to be blocked, so attention should be paid to the drying and cleaning of the system. Generally, a dry filter is set in front of the capillary to prevent clogging.

  

  Thermal expansion valve: the regulating valve that controls the liquid supply of evaporator, and it is also the throttle valve of refrigeration device. Thermal expansion valve uses the change of superheat of refrigerant at evaporator outlet to adjust the flow. According to different structures, it can be divided into internal balance type and external balance type.

  

  Disadvantages of thermal expansion valve: low control precision and limited adjustment range. The diaphragm deformation of valve body is limited, which makes the change range of valve needle opening smaller, so the adjustment range of flow is small. When large flow regulation is required, it cannot be met. The high-temperature gas at the place where the signal feedback has a lag evaporator must first heat the shell of the temperature sensor, which has a large thermal inertia, leading to the lag of the reaction.

  

  2

  

  Electronic expansion valve: the application of electronic expansion valve overcomes the shortcomings of thermal expansion valve and provides conditions for the intelligence of refrigeration device. The electric signal generated by adjusting parameters is mainly used to control the voltage or current applied to the expansion valve, so as to achieve the purpose of adjustment, so that the control system of the electronic expansion valve is complicated and the price is high.

  

  Electronic expansion valve classification:

  

  Electromagnetic electronic expansion valve;

  

  Electric electronic expansion valve.

  

  4. Auxiliary equipment of refrigeration system

  

  Oil separator: The high-pressure gas (gaseous working medium and lubricating oil) from the compressor enters the oil separator to separate the lubricating oil from the working medium gas and flows down along the inner wall of the cylinder. The working gas is led out of the oil separator from the central pipe through the porous baffle. The separated lubricating oil is concentrated in the lower part of the oil separator and can be discharged regularly, or the lubricating oil can be automatically returned to the crankcase of the compressor by using the ball valve.

  

  Drying filter: The function of drying filter is to absorb moisture in refrigeration system, prevent impurities in the system from passing through, and prevent the pipeline of refrigeration system from being blocked by ice and dirt. Because the most easily blocked part of the system is the capillary (or expansion valve), the drying filter is usually installed between the condenser and the capillary (or expansion valve).

  

  Liquid storage tank: During the operation of the refrigeration system, the circulating amount of refrigerant in the system will change due to the change of working conditions or the adjustment of refrigeration capacity. Setting the liquid storage tank can balance and stabilize the refrigerant circulation in the system by using the liquid storage capacity of the liquid storage tank, so that the refrigeration system can be in normal operation. In addition, when a component in the refrigeration system fails and needs to be dismantled and repaired, the system refrigerant can be recovered to the liquid storage tank through certain operation methods.

  

  The liquid storage tank is generally arranged between the condenser and the throttling element, so that the refrigerant liquid in the condenser can smoothly enter the liquid storage tank. The position of the liquid storage tank should be lower than that of the condenser.

  

  Electromagnetic four-way reversing valve: after the electromagnetic coil is energized, it changes the action direction of the valve block in the valve body and changes the flow direction of the refrigerant. So as to achieve the purpose of cooling or heating.

  

  three

  

  Solenoid valve: Solenoid valve is usually installed in front of the expansion valve to directly control the amount of refrigerant entering the evaporator. It can also be installed before the compressor unloading cylinder to control the unloading of the compressor cylinder.

  

  There are two kinds:

  

  Direct opening and closing solenoid valve;

  

  Indirect solenoid valve.

  

  One-way valve: The one-way valve is usually connected in parallel with the auxiliary capillary, and the two are connected in series with the main capillary. One-way valve is a tubular element with a movable spherical or hemispherical plug made of stainless steel or nylon. Combined with capillary tube, it can adapt to two different operating conditions of refrigeration and heating.

  

  5. Types and States of Refrigerant

  

  Air conditioning refrigerants mainly include R22, R410A and R32.

  

  R22 is a medium-temperature refrigerant, with the standard of -40.8 degrees, the solubility of water in R22 is very small, and it is mutually soluble with mineral oil, and R22 does not burn or explode, with little toxicity and strong permeability.

  

  R410A is a HFC refrigerant which is composed of R32 and R125 by 50% and 50% by mass. [This article comes from WeChat official account, a refrigeration encyclopedia” target=_blank>, which belongs to a near azeotrope, and its thermodynamic properties are very close to that of a single refrigerant. Compared with R22, R410A’s condensation pressure is increased by 1.6 times, and it is a high-pressure refrigerant, so it is necessary to improve the compression strength of the system.

  

  R32 is the abbreviation of difluoromethane, which is a kind of coolant with zero ozone loss potential. It is a gas at room temperature and a colorless and transparent liquid under its own pressure. It is soluble in oil and insoluble in water, and it is an energy-saving and carbon-reducing environment-friendly non-toxic refrigerant, but it is flammable and explosive!

  

  6. Refrigerant status

  

  Saturated refrigerant: Vapor-liquid conversion in saturated refrigerant is in transport equilibrium, and liquid and gas at this time are in saturation.

  

  There is a one-to-one correspondence between saturation temperature and saturation pressure, and the saturation pressure increases with the increase of saturation temperature, and one of them will change and the other will change accordingly. In the system, the refrigerant in the evaporator absorbs heat and the refrigerant in the condenser releases heat, where the refrigerant is saturated.

  

  Superheat: Under a certain pressure, the temperature of superheated steam exceeds the saturation temperature.

  

  Overheating: the temperature of refrigerant vapor in superheated refrigerant is higher than the saturation temperature under the corresponding saturation pressure, and the liquid refrigerant will overheat after evaporation. In the case of overheating, there is no one-to-one correspondence between the temperature and pressure of refrigerant gas.

  

  Near the outlet of the evaporator, the refrigerant continues to absorb heat after complete evaporation and becomes superheated refrigerant with a temperature higher than the saturation temperature. The refrigerant enters the compressor through the suction pipe in case of overheating.

  

  Supercooling: The liquid temperature of the supercooled refrigerant is lower than the saturation temperature at the corresponding saturation pressure, and supercooling will only occur when there is no steam in the fluid refrigerant. In the case of supercooling, there is no one-to-one correspondence between the temperature and pressure of refrigerant liquid.

  

  Between the outlet of the condenser and the throttle valve, the refrigerant may continue to cool exothermically and become supercooled after condensing into saturated liquid.

COVID_19 variant KP.2 has spread in many countries and is highly contagious

According to related reports, radio dongle To a large extent, it leads the changes of market conditions. https://www.coralnewenergy.com/

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.
