空调使用铜管的优势
Advantages of using copper tube in air conditioning
空调室内机与室外机需要连接材料进行连接，普通连接材料包括铜管和铝管。目前，空调连接材料使用最普遍的是空调铜管，因为制冷剂要在蒸发器中吸收热量，再在冷凝器中释放热量，空调铜管与散热片相连，连接管内通过的是制冷剂，即氟利昂。制冷剂用的铜管质量好坏直接影响着空调的制冷效果。
The indoor unit and outdoor unit of air conditioner need to be connected by connecting materials, common connecting materials include copper pipe and aluminum pipe. At present, the most commonly used air-conditioning connecting material is the air-conditioning copper pipe, because the refrigerant needs to absorb heat in the evaporator, and then release heat in the condenser. The air-conditioning copper pipe is connected with the heat sink, and the connecting pipe passes through the refrigerant, namely Freon. The quality of copper tube for refrigerant directly affects the refrigeration effect of air conditioner.
铜管耐压力高，不易腐蚀，使用寿命长。制冷铜管的导热性、焊接性能、机械强度较铝管好，但价格略贵。
The copper tube has high pressure resistance, is not easy to corrode, and has long service life. The thermal conductivity, weldability and mechanical strength of the copper tube are better than that of the aluminum tube, but the price is a little expensive.
