Function of air conditioning copper tube

Air conditioning is a common household appliance now. There are many accessories for air conditioners, and copper tubes for air conditioners are absolutely indispensable. Here, Bian Xiao briefly talks about the role of air conditioning pipes in air conditioning.

Connecting internal and external machines

There will be two connecting pipes with different sizes in the air conditioning and refrigeration system. The thick one is called big tube, and the thin one is called small tube. Their function is to connect the indoor and outdoor units of the air conditioner, so that there is a closed system between the indoor and outdoor units, and the air conditioner refrigerant can circulate between the indoor and outdoor units.

Refrigeration and heating

It depends on whether the air conditioner is cooling or heating. When heating, the refrigerant flows from the external machine to the internal machine through the large pipe, and then to the condenser and compressor of the external machine through the small pipe; If it is refrigeration, the refrigerant enters the internal machine from the external machine through the small tube to show off, and then returns to the external machine through the large tube.
