What is an air conditioner heat exchanger used for?

It is mainly used for the utilization of waste heat. For example, a chemical plant produces a large amount of high-temperature exhaust gas, and it is a waste to put it directly into the air, so people put some flowing gas or cold water that needs to be preheated outside the hot gas pipe, and heat them to produce high-temperature water vapor or preheat some cold gas. The preheated gas is of course used for chemical reactions, while the high-temperature water vapor produced after cold water is heated can be used for power generation, bathing, cooking, etc., and even heating.

So that's why some factories can generate electricity. Of course, in addition to industrial use, there are many people who use its principles in daily life, such as air conditioning. In fact, the boiler we usually talk about is the simplest heat exchanger, its principle is that the combustion of coal produces high-temperature gases in the boiler through the winding tubes and finally out of the chimney, and the cold water is heated outside the tubes.

I probably haven't seen the inside of a boiler.

To put it simply, the hot becomes cool, and the cold becomes hot.

The heat exchanger is the main component of the air conditioner, which plays the role of cold and heat conversion, and is widely used in household air conditioners and household air conditioners.

You can see this by yourself.

Top dog! People are talking about air conditioning! I'm working in Panasonic, and I'm telling you, there's no heat exchanger in the air conditioner, but there's a condenser, and I don't know if you're talking about it, it's the one that has a fan on the outside, and it's rented to drain the heat, and the principle is to use freon as a heat carrier, and it's a kind of gas that is compressed and easily liquefied, and it needs to absorb heat when it is vaporized, and it liquefies it outside and sends it in for vaporization, and the condenser is the one in the room.

It is equivalent to an energy-saving fresh air fan, it has 2 holes on one side, one is the fresh air outlet hole, and the other is the indoor gas discharge hole (the hole is connected to the air duct), so that the heat exchange of 2 different states of gas will occur in the heat exchanger, in fact, this is similar to the economizer nature of the boiler.

There are two types of heat exchangers.

First, the hot water that cools the engine is dissipated through the heater, and then the fan blows the heat out of the car to form hot air.

Second, the evaporator and condenser make the refrigerant change from a high-temperature and high-pressure state to a low-temperature and low-pressure state through a compressor, the evaporator cools down, and the fan blows the cool breeze into the car.

The above is a car air conditioner.

Household air conditioners are similar.

Enables heat exchange between medium and air.

The heat exchanger on the air conditioner product itself is a heat exchanger, which realizes the transfer of heat between the medium and the air.

The water in the heat exchanger is the heat exchange end product. The heat exchanger runs inside the refrigerant.

It is a fluorine system heat exchanger.

The flow of hot water into the heat exchanger is controlled by a hot water valve, which regulates the temperature of the heat exchanger surface, and when the gas cooled by the evaporator passes through the heat exchanger at different temperatures, it is heated to the different temperature that the customer wants.

Efficient heat exchange, energy saving and environmental protection, air conditioning heat exchanger in addition to increasing the static pressure by 20%, can supply air from the air that has been discharged up to 75% of the heat energy, thereby greatly reducing the heat loss during refrigeration and heating, compared with the ordinary ventilation fan can save 40% of the electricity per year, the energy saving effect is obvious.

Heat exchange, environmental protection, air conditioning heat exchanger in the increase of static pressure at the same time, can be up to the exhaust heat, thereby greatly reducing the heat loss and heating in the refrigeration process. Compared with ordinary ventilation fans, it can save electricity every year, and the savings are obvious.

The principle of an air conditioning heat exchanger is that the compressor compresses the refrigerant into a high-pressure saturated gas (ammonia or freon), which is then condensed by a condenser.

After throttling through the throttling device, it enters the evaporator for cooling and exchanges the medium to be cooled. For example, an evaporator is connected to every room of the building. The serpentine tube in the evaporator heats the air and blows it into the chamber through the air flow.

The refrigerant in the serpentine tube of the evaporator becomes low-pressure steam and returns to the compressor, the compressor compresses the refrigerant, and the refrigeration system is completed through recycling.

The principle of heating and cooling is the same, i.e., the reverse Carnot cycle. The principle of refrigeration is different from that of condensers and evaporators, i.e. compressor-evaporator-throttling-condenser.

Air conditioning heat exchanger is an important part of air-land transfer, which is mainly used to transfer heat between indoor and outdoor to achieve indoor temperature control.

Air conditioner heat exchangers are divided into two types: evaporator and condenser. Among them, the evaporator is usually installed indoors, mainly through the principle of evaporative refrigeration to reduce the indoor temperature. The condenser is usually installed outdoors and is responsible for transferring heat from the indoor area to the outside.

Specifically, when the indoor unit of the air conditioner is working, the indoor air is blown through the evaporator by the fan, and the refrigerant in the evaporator will also evaporate and absorb the indoor heat in the process, and at the same time produce cold air, so as to achieve the effect of cooling and early resistance.

When the outdoor unit of the air conditioner is working, the coolant will be compressed to high temperature and discharged, and after the heat hooks up with the outdoor unit, it enters the condenser, transfers the heat to the outdoor environment through heat dissipation, and cools the refrigerant into liquid, and then is sent back to the evaporator for further recycling.

To sum up, the principle of air conditioning heat exchanger is to use refrigerant in the process of evaporation and condensation to create cold and heat effects, and transfer heat between indoor and outdoor to achieve the purpose of air conditioning cooling or heating.

The air conditioner heater usually refers to the evaporator in the indoor unit and the condenser in the outdoor unit. Here's how it works:

1.Evaporator: The evaporator is one of the heat exchangers in the air conditioning system, and its main function is to absorb the heat from the indoor air into the refrigerant and reduce the indoor temperature.

Specifically, when the indoor hot air passes through the evaporator, the refrigerant expands in the evaporator and absorbs heat, thereby absorbing the heat in the air, and the refrigerant itself becomes a low-temperature and low-pressure state.

2.Condenser: The condenser is another heat exchanger in the air conditioning system, and its main function is to dissipate the heat in the refrigerant to the outside to complete the refrigeration cycle.

Specifically, when the refrigerant absorbs the heat from the evaporator to the indoor heat, it will be sent to the condenser of the outdoor unit for recompression or front, at this time, the refrigerant will release the absorbed heat and transfer the heat to the outdoor air, so that the refrigerant will become a high-temperature and high-pressure gaseous state again, returning to the starting point of the refrigeration cycle.

In short, the function of the air conditioning heat exchanger is to complete the indoor air cooling through the circulation of refrigerant, so as to achieve the cooling effect of the air conditioning system. The evaporator and condenser play the role of heat absorption and heat release respectively in the refrigeration cycle, and are an important part of the realization of air conditioning work.

1.When the air conditioner is in use, the dust cover will be removed so that the dust will cover it. Use a clean cloth to wipe off the dust on the indoor unit of the air conditioner, and then sprinkle some water on it.

Don't spill too much to help wipe the dust. A small vacuum cleaner can be used to clean the corners of the air conditioner, ventilation holes, air deflectors, and other places that are not easy to clean.

2.After cleaning the cover of the indoor unit of the air conditioner, open the front cover, as dust will adhere to the inside of the front cover. Remove the front cover and scrub with a damp cloth.

After the front cover is air-dried, it is the filter. If there is not too much dust on the filter screen, you can remove it and clean it directly with clean water. If there is too much dust, you can add detergent to the water to wash it and then rinse it off with clean water.

3.After cleaning the filter, clean the air conditioner fins. It should be clear to use an aircon cleaner that is specifically designed to clean air conditioners.

Spray the cleaning agent evenly on the air conditioner radiators. After about half an hour, the cleaner will dissolve the dust and dirt on the air conditioner's fins, and then turn on the air conditioner to refrigerate. After running for about half an hour, you will find dirty water flowing out of the outlet pipe outside the air conditioner, which is the dirt on the air conditioner's radiator.

Chemical cleaning agents and fungicides can be added to clean and disperse the floating rust, scale, oil, bacteria and algae in the system, and reduce them to a clean metal surface;

Heat exchangers work by transferring part of the heat to a cold fluid to meet the specified process requirements.

Heat exchanger, also known as heat exchanger or heat exchange equipment, is a device that transfers heat from hot fluid to cold fluid to meet the specified process requirements, and is an industrial application of convection heat transfer and heat conduction. Household heat exchangers help people solve the problem of collective heating of homes and hot water in winter. At present, the more popular one on the market is the stainless steel heat exchange locator.

According to the data of the heat exchange equipment promotion center, the heat exchange effect of stainless steel heat exchanger has a better heat transfer effect than that of traditional carbon steel heat exchanger, and its service life is longer.

Heat exchanger

Heat exchangers can be classified in different ways. According to its operation process, it can be divided into three categories: wall type, hybrid type and regenerative type; According to the compactness of its surface, it can be divided into two categories: compact and non-compact. Among them, the eddy current hot film heat exchanger adopts a stainless steel heat exchanger with the latest eddy current hot film heat transfer technology, which increases the heat transfer effect by changing the fluid movement state.

When the medium passes through the surface of the vortex tube, it strongly washes the surface of the tube, thereby improving the heat exchange efficiency. Up to 10000W m2. This structure realizes corrosion resistance, high temperature resistance, high pressure resistance, and anti-scaling functions.

The fluid channel of other types of heat exchangers is in the form of a fixed direction flow, which forms a circumferential flow on the surface of the heat exchanger tube, and the convective heat transfer coefficient is reduced.

Principle: The compressor compresses the refrigerant into a high-pressure saturated gas (ammonia or freon), which passes through the condenser.

Condensation. After throttling through the throttling device, it is passed into the evaporator.

, the medium to be cooled is cooled and heat exchanged. For example, if the evaporator is connected to each room in the building, the snake pipe in the evaporator will exchange heat with the air, and then blow the cold air into the air in the room through the air blast.

The refrigerant in the snake tube of the evaporator becomes low-pressure vapor after heat exchange, returns to the compressor, and is then compressed by the compressor, so that the recycling completes the refrigeration system.

Heating and cooling principle.

Same, i.e., inverse Carnot cycle.

Different from the refrigeration principle is the exchange of condenser and evaporator, i.e.: compressor - evaporator - throttling device - condenser.

The working principle of the heat exchanger, in fact, is very easy to understand, which is the heat exchange between cold and hot media.

Heat exchange. Air conditioning products are essentially the transfer of heat between different areas under the condition of consuming a certain amount of electricity, so as to achieve regional temperature reduction.

The system works with heat exchangers in indoor and outdoor machines, and the heat exchange between the refrigerant and the environmental medium is realized by the heat exchanger.

The heat exchanger is the heat exchange component.

What is the function of the heat exchanger of the air conditioner?

Working principle of fast clean total heat exchanger: The total heat exchanger perfectly combines the overall balanced ventilation design with efficient heat exchange. The core components are fans and heat exchangers.

The system brings in fresh air from the outside, and then expels the dirty air from the room, and completes the indoor air replacement without opening the window, improving the indoor air quality. At the same time, the incoming fresh air and the dirty air discharged from the room are exchanged in the heat exchanger, which reduces the influence of fresh air on the indoor temperature and improves human comfort. A full heat exchanger is the best way to ventilate an room.

Compared with other ventilation equipment, its biggest feature is that it contains a full heat exchange core, which can send air into the room or out of the house after heat exchange, so as to save energy consumption. In summer, the full heat exchanger core installed in the system can reduce the temperature of the outdoor air intake and enter the room in a way close to the room temperature; In winter, the pie stove can raise the low temperature of the outdoor air intake and enter the room at a higher temperature than the outdoor air, which can prevent indoor temperature loss and reduce energy consumption.

The full heat exchange fresh air ventilator is the most advanced fresh air ventilator at present, in addition to the functions of other fresh air ventilators, it also has the unique characteristics of two-way ventilation and good energy saving.

Two-way ventilation: built-in supply and exhaust fan, there are fans and pipes in the inlet and exhaust systems, and the air is supplied to the room through the inlet fan, and the exhaust fan is exhausted to the outside. It belongs to the "forced exhaust and forced air supply" system, and the fresh air is replaced in both directions to maintain enough fresh air in the room, which can effectively prevent air conditioning diseases.

In addition, the full heat exchange fresh air ventilator is equipped with different filter materials to filter the fresh air, and can filter 50%, and the introduced fresh air is of high quality.

High efficiency and energy saving: The full heat exchanger is different from the ordinary ventilator, which only discharges the indoor dirt gas directly to the outside, resulting in the loss of indoor temperature. The full heat exchanger is to exchange heat with the outdoor air before the outdoor air is introduced into the room, and the air pre-dust is pre-cooled and preheated and then introduced into the room, with an energy efficiency of 70%, which greatly reduces the indoor temperature loss, saves the cost of cooling and heating, and is more energy-saving and environmentally friendly.
