Summer is coming soon, so many families are ready to buy air conditioning. Without air conditioning, summer can not be spent at all. What role copper tubes play in air conditioning may be curious in the process of using them. In addition, why copper tubes are used in air conditioning should be known so as to achieve good use. What is the role of copper tubes in air conditioning? Why do air conditioners use copper tubes? What is the role of copper tubes in air conditioning?

1. The purpose of special air-conditioning copper pipe and fittings joints for connecting outdoor units with indoor units is to connect indoor units with outdoor units. The connecting pipe passes through the refrigerant (Freon, commonly known as snow species). For example, in the refrigeration mode (that is, in summer), the indoor machine absorbs the heat (exhaust air), and the snow seeds become low-pressure and medium-temperature snow seeds, and then go out to the outdoor machine through a larger copper tube. You can touch the larger copper tube with your hand, it feels colder, and there will be water on the surface.

2. Snow seeds are compressed by compressor outside through copper tube of air-conditioner, then become high temperature and high pressure snow seeds and enter heat exchanger of outdoor machine to release heat (fan rotating). Then, the medium-temperature and medium-pressure snow seeds enter the room through another copper tube (the smaller one), and pass throttle valve (with capillary copper tube or expansion valve, etc.) before entering the indoor machine. The function of the throttle valve is that the volume of the throttle valve is very small, but after passing the throttle valve, the volume suddenly increases, so the snow species will instantly become low-temperature and low-pressure snow species, and then absorb heat. This completes a refrigeration cycle. If it is a heating cycle, the opposite is true. So you should understand the function of two copper tubes in air conditioning.

Why do air conditioners use copper tubes?

1. The connection between indoor and outdoor units of air conditioning needs to be connected by connecting materials. Copper and aluminium pipes are widely used to connect indoor and outdoor air conditioners. At present, copper pipes are widely used in air-conditioning connection materials. Why? Because the refrigerant absorbs heat in the evaporator and releases heat in the condenser, the copper tube of the air conditioner is connected with the radiator outside, and the refrigerant (Freon, commonly known as snow) is passed through the connecting tube. Therefore, the quality of copper tubes used in this refrigerant directly affects the refrigeration effect of air conditioning.

2. Copper tube has high pressure resistance, is not easy to corrode, and its service life is longer than that of aluminium tube. The thermal conductivity of refrigeration copper tube is much better than that of aluminium tube, and its welding performance and mechanical strength are much better than that of aluminium tube. Of course, the price of air conditioning copper tube is also more expensive than that of aluminium tube. Many consumers in order to save money or greed for cheapness, they will refrigerator, air conditioner copper tube thinner or directly switch to aluminum tube, the price is relatively low, but of course, the performance is much worse than copper tube, refrigeration effect is not better than copper tube.

Looking at the above text, only people should have known what role copper tubes play in air conditioning. In fact, the role of copper tubes is relatively large. Because of this, it is loved by many people. In addition, for why copper tubes are used in air conditioning, because if air conditioning wants to play a better role, the role of copper tubes is inevitable.
