What's the difference between an air conditioned pure copper tube and an aluminum tube?
The copper tube has high heat transfer efficiency, corrosion resistance and good strength, but the price is expensive.The heat transfer efficiency of aluminum pipe is higher, the corrosion resistance is not good, but the price is much cheaper.
Copper tubes are durable and aluminum tubes leak easily.
For users, the difference is modest. If you need to use only intermediate machine, air conditioning copper connecting pipe than aluminum connecting pipe to some reliable air conditioning. The air-conditioner doesn't make any difference.
