What is the principle of air conditioning cooling What principle does air conditioning use to cool d

It is the air from the outside that is blown into the room by compression, and the compressed air absorbs heat as it recovers its volume (i.e., when it expands), thus cooling it.

It is the evaporation and cooling of fluorine, and the fluorine becomes a gas after absorbing heat indoors, and then it becomes a liquid after heat dissipation outside, and then it goes back to the indoor to absorb outdoor cooling, and the air conditioner is a carrier to carry fluorine, which helps it accelerate heat absorption and heat dissipation.

Liquefaction gasification endothermy, gas compression and exothermy, circulating refrigeration.

The operating principle of air conditioning refrigeration (taking household air conditioners as an example).

When the air conditioner is running for refrigeration, the low-temperature and low-pressure refrigerant gas is sucked in by the compressor and pressurized into high-temperature and high-pressure refrigerant gas, and the high-temperature and high-pressure refrigerant gas is exothermic in the outdoor heat exchanger (condensed through the condenser) into a medium-temperature and high-pressure liquid (the heat is carried away by the outdoor circulating air), and the medium-temperature and high-pressure liquid becomes a low-temperature and low-pressure liquid after throttling and depressurizing through the throttling parts. The low-temperature and low-pressure liquid refrigerant becomes a low-temperature and low-pressure gas after endothermic evaporation in the indoor heat exchanger (the indoor air is cooled and cooled through the surface of the heat exchanger to achieve the purpose of reducing the indoor temperature), and the low-temperature and low-pressure refrigerant gas is then inhaled by the compressor, and so on.

The principle of air conditioning is essentially different from that of an electric fan, and the room will of course become cooler soon!

Most of the refrigerants commonly used in air conditioners are freon, and the characteristic of freon is that when it changes from gaseous to liquid state, a large amount of heat is released. When the liquid state changes from a gaseous state, it absorbs a large amount of heat. (i.e., first absorbing heat and gasification and then liquefiing and heat release) air conditioners are designed according to this principle.

The compressor compresses the gaseous refrigerant into a gaseous refrigerant with high temperature and high pressure, and then sends it to the condenser (outdoor unit) to dissipate heat and becomes a liquid refrigerant at room temperature and high pressure, so the outdoor unit blows hot air.

Then to the capillary, into the evaporator (indoor unit), because the refrigerant from the capillary to the evaporator after the space suddenly increases, the pressure decreases, the liquid refrigerant will vaporize, into a gaseous low-temperature refrigerant, thus absorbing a large amount of heat.

The evaporator will become cold, and the fan of the indoor unit will blow the indoor air through the evaporator, so the indoor unit will blow cold air; When the water vapor in the air meets the cold evaporator, it will condense into water droplets and flow out down the water pipe, which is why the air conditioner will produce water.

1. The principle of air conditioning and refrigeration refers to the principle of air conditioning and refrigeration operation. After the air conditioner is energized, the low-pressure steam of the refrigerant in the refrigeration system is sucked in by the compressor and compressed into high-pressure steam and then discharged to the cold condenser, and the indoor air is continuously circulated and flowed to achieve the purpose of reducing the temperature.

2. The outdoor air drawn in by the axial fan flows through the condenser, taking away the heat of the cherry blossom released by the refrigerant, and condensing the high-pressure refrigerant vapor into high-pressure liquid. The high-pressure liquid is sprayed into the evaporator after passing through the filter and throttling mechanism, and evaporates at the corresponding low pressure to absorb the surrounding heat. At the same time, the cross-flow fan continuously enters the ribs of the evaporator for heat exchange, and sends the cooled air to the room after heat release.

The national scientific research team has developed an air-conditioned clothing that can be worn on the body using aerospace technology, what is the working principle of the air-conditioned clothing? The following is the relevant content that I have carefully compiled for you about what is the cooling principle of the air-conditioned clothing, I hope you will like it!

What is the cooling principle of air-conditioned clothes Can air-conditioned clothes really cool down How air-conditioned clothes work.

What is an air-conditioned suit.

Recently, it has been hot for several days, and the words that CD Jun said were hot were sweating. The 206 Institute of the Second Research Institute of China Aerospace Science and Industry Corporation has developed an air-conditioned clothing that can be worn on the body using aerospace technology, and has been put into the market. The product is composed of a liquid-cooled vest, a refrigeration unit and a power supply, and the air conditioner is small in size, light in weight, easy to use, and can be carried in any position on the body without affecting normal work and life.

What is the working principle of the air-conditioned suit.

The outermost layer of the smart thermostat is a solar panel mounted on the back of the human body, which stores solar energy in a lithium battery, so that you can get a stable power source**. "If it is a shipyard worker, once it enters the cabin, it will not be exposed to the sun, in order to ensure normal use, this intelligent thermostat air conditioner can also be connected to the mains for use, only need to add a voltage converter, the 220 volt voltage can be transformed to make it run normally. ”

If you are wearing this smart thermostat air conditioner, the inside of the clothes will reach the desired temperature after about 10 seconds of power-on. In addition, its "smart" feature is reflected in its automatic opening and closing, depending on the user's desired temperature range. Zhang Xinliang said that in a special semiconductor, the thermal insulation layer between the high temperature part and the low temperature part is required to completely block the heat transfer between the two, and the choice of this thermal insulation material is the difficulty and key to the research and development of this technology, "In the future, we also need to find better thermal insulation materials to further improve the operation effect of this intelligent thermostatic air conditioner."

What netizens said about air-conditioned clothing.

I really hope that ** will give each sanitation worker one piece! The big bosses of construction sites are also handing out a welfare to migrant workers. Ordinary people rarely use it, and now they are all air conditioners, mainly working in high temperatures.

First give the police, surveying and mapping, sanitation to a set, and then it is announced that the market **, express delivery, workers, etc. can be purchased.

This product was made by our company as early as 3 years ago. At that time, I also made a special dress for the traffic police, including a fan. The cost of one piece is no less than 3,500 yuan.

I wonder if this benefit is not available to everyone! How many people will be willing to buy it, and it is estimated that there will be only a few samples to try.

3.Why does an air conditioner cool down?

Nowadays, people use air conditioning fans.

It is becoming more and more common, not only can bring us coolness, but also be more environmentally friendly, but what is the principle of air conditioning fan? How about the cooling effect of the air conditioner fan? In fact, an air conditioner fan is an electric fan equipped with a water cooling device.

No compressors, no freons.

With a variety of functions such as air supply, refrigeration, air purification and humidification, the following is a specific introduction to the principle of air conditioning fan? How about the cooling effect of the air conditioner fan?

What is the principle of an air conditioner fan? How about the cooling effect of the air conditioner fan?

For the refrigeration fan, it is actually an electric fan equipped with a water cooling device, relying on the built-in water pump to keep the water circulating in the motor, so as to cool the surrounding air, so that the air sent out is cold, the refrigeration fan is based on water as the medium, can send out the same wind as the water temperature in a short time, but because it itself cannot be refrigerated, so it needs to continuously inject the required temperature of water into it to continue to keep sending cold air, in short, In the summer, the temperature in the room is 30 degrees Celsius.

Then we will inject 1 degree Celsius of water into the cooling fan, so that we can maintain the cold air pattern for at least half an hour, and after half an hour, the water temperature will be assimilated by the temperature in the room, so we should not add too much water when adding water.

What is the principle of an air conditioner fan?

Evaporative cooling fan cooling principle:

The equipment cooling circulating water pump extracts the ice water from the water tank to the water separator.

The water separator evenly delivers the ice water to the evaporator.

After the evaporator is immersed, a film of ice water is formed on the surface; After the high-volume fan is activated, it is told to suck into the outdoor airflow of the evaporator to quickly evaporate the ice water on the ice water film from the liquid state to the gaseous state, absorb the heat in the hot air, and send the cold air out at high speed through the air outlet!

Super absorbent fiber evaporator:

It is manufactured by modern scientific technology, honeycomb design, large hydrophilic area, large air inlet and outlet volume, so that the water can quickly absorb heat and evaporate, and the cooling effect is more significant; The greater the evaporation per unit time, the more heat is absorbed, and the cooling effect is faster.

How about the cooling effect of the air conditioner fan?

The temperature of the air conditioning fan can be reduced by about 5-6 degrees compared with ordinary fans, with low power consumption, and some products also have a heating effect and negative ions.

Function. The refrigeration effect is not very good for large areas, there is no dehumidification function before imitation, it is not easy to use in places with high temperatures, and it will increase the humidity in the air when used, but it is more suitable for areas with drier weather.

The above is about the principle of air conditioning fan? How about the cooling effect of the air conditioner fan? The simple introduction of the air conditioning fan is only 60-80w when starting refrigeration, which can be said to be a very environmentally friendly product, but the specific effect is definitely not as good as the air conditioning refrigeration effect, but for small area use, the air conditioning fan is still a good choice.

The air-conditioning fan has a good effect of timely refrigeration, because the principle of the air-conditioning fan is that the fan is cooled with water, and the spray water is used to absorb air heat and blow out cold air. Compared with air conditioning, the air conditioning fan has a more direct and fast cooling effect, but for the overall cooling of the room, the effect is still not as good as that of air conditioning.

Air conditioning fans are more suitable for areas that are not so hot in summer, and if it is a relatively hot city and environment, the dispersion and air cooling effect of air conditioning fans is completely insufficient. It's okay to use it below 32 degrees, but when the temperature is high, it's not good at all. Air conditioning fan is a new concept of fan, both air supply, refrigeration, heating and air purification, humidification and other functions, can send out cold air can also send warm air, whether it is in the first or energy health are of great benefit, very suitable for salaried people and residents of the old city to use, he combines the principle of fan and air conditioning, the two collocations combined, from the overall priority to the fan and air conditioning, the appearance of the business is very beautiful and the function is more.

Air conditioning fan saves electricity. The actual efficiency of the air conditioning fan is ultra-low, because to produce ice, and then the ice and snow are washed away, melted and cooled, it is far less than using air conditioning to cool down. The air conditioner fan is equipped with an electric fan with a water cooling device, and the built-in water pump continuously circulates the water shed in the machine to cool the surrounding air, so that the air sent by the fan has a cold feeling.

In summer, the air is hot and humid, and cold wind will inevitably form condensation at the air outlet and other places.

Experts point out that bacteria are most likely to grow here, and bacteria will blow into the air with cold winds, and the wind they blow out is damp, so the elderly and children with poor immunity should be cautious about using air conditioning fans.

The relative humidity of the air blowing out of the air conditioner fan is above 80%, which greatly increases the indoor humidity. In summer, when the humidity in the air is high, the human sweat is not easy to discharge, and it will feel stuffy. When the outside temperature exceeds 33 or the air humidity is high, the air conditioning fan will not only not cool down, but will make people feel uncomfortable due to the high humidity, and what is really needed in summer is dehumidification rather than humidification.

Household air conditioners, whether they are hang-up or cabinet-set, do not have a fresh air function, that is to say, they will not exchange with the outdoor air; It's just that the indoor air circulates back and forth through the heat exchanger of the indoor unit to heat up or cool down.

An air conditioner is an air conditioner. It refers to the equipment that uses artificial means to regulate and control the temperature, humidity, flow rate and other parameters of the ambient air in the building or structure.

Functional cooling. In the design and manufacture of air conditioners, it is generally allowed to control the temperature between 16 and 32. If the temperature is set too low, on the one hand, it will increase unnecessary power consumption, and on the other hand, when the temperature difference between indoor and outdoor is too large, people can not quickly adapt to the temperature change when entering and leaving the room.

Air conditioners are accompanied by dehumidification during the refrigeration process. The relative humidity of the environment where people feel comfortable should be around 40-60%, and when the relative humidity is too high above 90%, even if the temperature is within the comfortable range, the person still feels bad.

The cooling state of the air conditioner is cooling, and the heating state is heating up.

Physical cooling refers to the use of a temperature lower than the human body to act on the local or systemic body to achieve the purpose of reducing congestion or bleeding, reducing inflammation, analgesia, cooling, and reducing cell metabolism. Here are 5 physical cooling tips that you can do at home:

01 Warm water scrub bath method.

Use a warm towel (32 34) below the patient's body temperature to repeatedly and gently wipe the major blood vessels, such as the sides of the neck, under the armpits, and in the groin (the base of the thighs).

Scrub bath sequence: both upper limbs, two lower limbs, and two lower limbs.

Precautions: When scrubbing the bath, ice packs are generally placed on the head to prevent epidermal vasoconstriction and head congestion during the scrub bath; A hot water bottle is placed on the sole of the foot to make the patient feel comfortable and can also reduce head congestion.

Do not take more than 20 minutes during the warm water bath to avoid the patient catching a cold After the bath, attention should be paid to observing whether the patient's ** surface is red, pale, bleeding spots, and paresthesia.

02, ice pack cooling method.

Scope of application: patients with high fever (general body temperature above 39) Method: When the body temperature is too high, wrap the ice pack with a towel and place it on the patient's armpit and groin (the root of the thigh).

Frequency: 10-30 minutes each time to avoid local frostbite.

Precautions: Observe at any time, if there is local purple, numbness and frostbite, stop using immediately. Ensure that the ice lead bag is complete, no water leakage, the cloth cover is dry, and replace it immediately after the ice melts. The pressure of the ice pack should not be too high so as not to affect blood circulation.

03, towel cold compress method.

After soaking the towel in cold water, wring it out slightly, apply the cold towel to the forehead, and then soak it in cold water when the towel is hot. You can also fill the hot water bottle with ice water or put in crushed ice cubes, put a layer of cloth and put it under your head, and the Xiaoice bag can be placed under the armpits, groin, etc. Pay attention to the replacement part, and the time should not be too long to prevent frostbite.

04, hot water foot soaking method.

Foot soaking can improve blood circulation and relieve discomfort while also helping to cool down.

05. Drink more hot water.

Fever is a process in which the body consumes water, and drinking more water during fever can speed up sweating, urination, and promote the discharge of toxins and metabolic wastes in the body, which is conducive to the condition as soon as possible**.
