Why copper tube is widely used in air conditioning or refrigerant system?

    The pipeline of air conditioning or refrigerant system generally indicates copper pipe. Why does air conditioning or refrigerant system choose copper pipe as the system pipeline? As we all know, refrigerant itself is corrosive to a certain extent, which means that PPR, PEX and other rubber and plastic pipes cannot be used, so the final choice is nothing but steel pipe, aluminum pipe and copper pipe.

    1. Steel pipe is not suitable for whole pipe installation, which means that there will be a lot of joints in the system. The refrigerant system pipe transports high pressure gas and liquid, so the joint is very easy to rust. That is to say, steel pipe is not suitable.

    2. Aluminum tube cannot do the bell mouth. Besides it holds the characteristics of poor pressure and oxidation resistance, as a result, it is easy to leak. Therefore, aluminum tube is not suitable either.

    3. Copper pipe is widely used in whole pipe installation. It has the advantages of good ductility, excellent oxidation resistance, good pressure resistance, leak proof, strong thermal conductivity, higher heat transfer efficiency. As a result, copper pipe is generally used in air conditioning or refrigerant system.
