Now a part of the connecting pipe of the air conditioner from the past to pure copper aluminum copper combined pipe, aluminum copper pipe is better seller says. Is it better in the end? Please help me professional fans.
Surely all copper tubes are better. If using copper aluminum tube, when can not be good?. I have a good reason here only one: if using two kinds of materials of copper aluminum pipe as the performance of the different coefficients of expansion in the summer if installed correctly, it may in the winter there will be gaps to the leakage of refrigerant.
The use of copper aluminum tube is due to copper prices in recent years is too high, the adoption of cost reduction measures, the use should be little difference, compared to pure copper pipe is better.
Air conditioning connecting tube using copper and aluminum composite pipe is certainly not good, but cheaper.The connecting pipe of the copper aluminum composite pipe is an aluminum tube in the middle, and the copper pipe is welded at both ends, and there are several reasons for the bad:1, welding position is easy leaking and physical reaction.2, aluminum tube easy flat, fold.
