Why do air conditioners need copper pipes?

When everyone uses air conditioners, I don't know if they have found that they need to use copper pipes to achieve the effect of heat preservation. Let's take a look at why the air conditioner needs 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 conditioner connection material is air conditioner copper pipe.

       2. 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.

       3. The quotations of general decoration companies and maintenance companies are around 100-120 yuan per meter, but in fact, they are purchased in kilograms, which is about 45 yuan per kilogram. Set the price, generally speaking, the price of copper pipes with different diameters is different.

       Fourth, 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.

       5. In order to save money or greedy for cheap, many consumers thin the copper pipes of refrigerators and air conditioners or directly use aluminum pipes, and the price is relatively lower, but the performance is of course much worse than that of copper pipes, and the cooling effect is also Nothing is better than cooling with copper pipes.
