What is the role of the copper pipe in the air conditioner?
1. The purpose of the special air-conditioning copper pipes and fittings for the connection between the outdoor unit and the indoor unit is to connect the indoor unit and the outdoor unit. The refrigerant (Freon, commonly known as refrigerant) passes through the connecting pipe. For example, in the cooling mode (that is, in summer), the indoor unit absorbs the indoor heat (exhaust cold air), and after the refrigerant becomes a low-pressure medium-temperature refrigerant, it is sent to the outdoor unit through a larger copper pipe. You can touch the larger copper pipe with your hand and it will feel colder and there will be water on the surface.
2. The refrigerant exits the outdoor through the air-conditioning copper tube and is compressed by the compressor to become high temperature and high-pressure refrigerant and enters the outdoor unit heat exchanger to release heat (the fan rotates). Then the refrigerant changes to medium temperature and medium pressure and enters the room through another copper pipe (the smaller one), and before entering the indoor unit, it passes through the throttle valve (with capillary copper pipe or expansion valve, etc.), which is used to cut off the throttle valve. The volume is very small, but after the throttle valve is passed, the volume suddenly increases, so the refrigerant will instantly become a low-temperature and low-pressure refrigerant, so it absorbs heat. This completes a refrigeration cycle. In the case of a heating cycle, the opposite is true. So you should understand the role of the two air-conditioning copper pipes.
Why do air conditioners use copper pipes?
1. The connection between the indoor unit and the outdoor unit of the air conditioner requires connecting materials. The materials commonly used to connect the indoor unit and the outdoor unit of the air conditioner are copper pipes and aluminum pipes. At present, the most commonly used air-conditioning connecting material is air-conditioning copper pipes. why? Because the refrigerant eventually absorbs heat in the evaporator and releases heat in the condenser, the outside of the air-conditioning copper pipe must be connected to the heat sink, and the refrigerant (Freon, commonly known as snow) passes through the connecting pipe. Therefore, the quality of the copper tube used for this refrigerant directly affects the cooling effect of the air conditioner.
2. The copper tube has high-pressure resistance, is not easy to corrode, and has a longer service life than the aluminum tube; the thermal conductivity of the refrigeration copper tube is much better than that of the aluminum tube, and the welding performance and mechanical strength are far better than those of the aluminum tube. The price will also be more expensive than the aluminum tube. In order to save money or be greedy for cheap, many consumers thin the copper pipes of refrigerators and air conditioners or directly use aluminum pipes. The price is relatively lower, but the performance is of course much worse than that of copper pipes, and the cooling effect is not comparable The cooling effect of copper pipes is good.
After reading the above text, only people should already know the role of copper pipes for air conditioners. In fact, the effect is relatively large. Because of this, it is loved by many people. , Because if the air conditioner wants to play a better role, then the role of the copper pipe is inevitable.
