What is the role of the copper pipe of the air conditioner?
1. The purpose of the special copper pipe and accessory joints for connecting 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 (i.e. in summer), the indoor unit absorbs the heat in the room (exhausts cold air), and the refrigerant becomes a low-pressure medium-temperature refrigerant, and then goes out to the outdoor unit through a larger copper pipe. You can touch the larger copper pipe with your hand, it feels colder, and there will be water on the surface.
2. The refrigerant goes out of the room through the copper pipe of the air conditioner, and after being compressed by the compressor, it becomes a high-temperature and high-pressure refrigerant and enters the outdoor unit heat exchanger to release heat (the fan rotates). Then the refrigerant becomes a medium-temperature and medium-pressure refrigerant and enters the room through another copper pipe (a smaller one). Before entering the indoor unit, it passes through a throttle valve (capillary copper tube or expansion valve, etc.). The function is that the cross-sectional volume of the throttle valve is very small, but after passing the throttle valve, the volume suddenly increases, so the refrigerant will instantly become a low-temperature and low-pressure refrigerant, and then absorb heat. This completes a refrigeration cycle. If it is a heating cycle, it is the opposite. Now you should understand the role of two copper pipes for air conditioners.
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 for connecting the indoor unit and the outdoor unit of the air conditioner are copper pipes and aluminum pipes. At present, the most commonly used connecting materials for air conditioners are copper pipes for air conditioners. Why? Because the refrigerant will eventually absorb heat in the evaporator and release heat in the condenser. The outside of the air conditioner copper pipe must be connected to the heat sink, and the refrigerant (Freon, commonly known as refrigerant) passes through the connecting pipe. Therefore, the quality of the copper pipe used for this refrigerant directly affects the cooling effect of the air conditioner.
2. The copper pipe has high pressure resistance, is not easy to corrode, and has a longer service life than the aluminum pipe; the thermal conductivity of the refrigeration copper pipe is much better than that of the aluminum pipe, and the welding performance and mechanical strength are also much better than aluminum. Of course, the price of the air conditioner copper pipe will be more expensive than that of the aluminum pipe. In order to save money or seek cheapness, many consumers thin the copper tubes of refrigerators and air conditioners or directly use aluminum tubes, which makes the price relatively lower, but the performance is of course much worse than that of copper tubes, and the cooling effect is not as good as that of copper tubes.
After reading the above text, people should already know what the role of copper tubes in air conditioners is. In fact, the role is relatively large. Because of this, it is loved by many people. In addition, as for why copper tubes are used in air conditioners, if the air conditioner wants to play a better role, then the role of copper tubes is inevitable.
