Why does the air conditioner use a copper tube to deliver coolant?
Why air conditioners use copper tubes to transport refrigerants for the following reasonsCorrosion resistance: air conditioning in the work process, the tube surface temperature is very low, will the water vapor in the air into water, adsorption on the surface, if it is iron pipe, life certainly won't be very often.For installation: the installation of air-conditioning in accordance with the different structure of the house, you need to bend the tube shape, which is the most appropriate copper tube. There are joint bell mouth, tube, welding, iron is easier than.
Copper tube conducts heat quickly. Fast cooling, the same fast cooling.Also useful for zinc tubes, used more in the refrigerator. The hardness of zinc pipe is inferior to that of copper tube. It is generally used in the relatively good refrigerator sealed condenser.
The small density and soft texture of aluminum pipe can not compare with copper tube in mechanical performance and bending performance.The density of aluminum and copper is different, the cross-section is not the same, and if the aluminum tube and copper pipe are connected, the connection may be unstable welding, easy to cause refrigerant leakage, and may even explode.Aluminum and copper connection easily lead to corrosion of aluminum tubes, resulting in cooling, heating effect worse, and even cause air-conditioning can not work properly. ?Due to the different material, half life is almost only copper aluminum pipe, the cooling effect is relatively worse due to bending performance than copper, if consumers want to move again, bending tubes, very difficult, basically need to replace the new pipe.
