Question:

Is the air conditioner aluminum tube or copper tube?

Is the air conditioner aluminum tube or copper tube?

Answer:

Copper tubes, of course, will last long and will not corrode.
Copper, of course. Copper has shrinkage, ductility, and high prices
Good brass.So far, the "aluminum substituting copper" project which has been implemented or is being implemented by various air conditioner manufacturers has not been successful, because many problems that can not be solved at present are met.Only a few manufacturers still insist on the inner and outer connecting pipe of split air conditioner, and the part is made of aluminium tube.The air conditioning system working pressure is relatively high, the use of R22 refrigerant air conditioning maximum working pressure can reach more than 30 kilograms, using R410a refrigerant air conditioning maximum working pressure can reach more than 40 kilograms; such a high working pressure for welding demanding the use of aluminum tube, once the welding quality is not good, it is prone to this problem is it a.Second, the use of aluminum air conditioning, when the user moves, air conditioning repair, air conditioning displacement =, part of the use of aluminum connecting pipe to do air conditioning, the connecting pipe basically not reusable, easy to deformation and damage.Third, the oxidation resistance of aluminum tubes is much worse than that of copper tubes, and the aluminum tubes used on the air conditioners will be oxidized and corroded for many years.
