In the air conditioning system, the refrigerant pipe is the main refrigeration component that the air conditioner, heat exchanger, valve, compressor and other refrigeration liquid will flow through, which is usually copper pipe.

The air conditioning system sends cold or hot water to the end, and there are several ways to divide it from the medium to be escorted. One is to directly supply air, the other is to escort cold / hot water, and the other is to directly take refrigerant.

1. Remove refrigerant

For the system that directly uses refrigerant, like VRV system, the refrigerant pipe will directly enter the air-conditioning space to connect the outdoor host and indoor unit.

2. Air supply and hot and cold water supply

If it is a system of direct air supply and cold and hot water escort, the refrigerant pipeline is generally concentrated near the host.

In the case of dual supply system, the refrigerant pipeline is located in the outdoor host, and the indoor and outdoor connection is the water pipe with load cooling effect.

If the refrigerant pipeline is too long, the contraction valve should generally adopt the form of external equilibrium to cope with the pressure drop from the evaporator inlet to the compressor suction port.

Why do air conditioners use copper tubes?

01. For the connection between the indoor unit and the outdoor unit of the ordinary split air conditioner, the connection data required shall be stopped. Copper and aluminum tubes are commonly used to connect indoor and outdoor units of air conditioners.

At present, the common use of air-conditioning connection data is air-conditioning copper pipe. Why? This is because the refrigerant absorbs heat in the evaporator and then releases heat in the condenser. The outside of the refrigerant pipe of the air conditioner is also connected with the radiator, and the connecting pipe passes through refrigerant.

02. Moreover, copper pipe has high pressure resistance, is not easy to corrosion, and its service life is longer than that of aluminum pipe; The thermal conductivity of refrigeration copper pipe is much better than aluminum pipe, and the welding performance and mechanical strength are far better than aluminum pipe, but the price of air conditioning copper pipe will be more expensive than aluminum pipe.

Therefore, the quality of the copper tubes used for this refrigerant directly affects the refrigeration effect of the air conditioner.

After reading the above text, everyone should have known about the role of the refrigerant pipe of the air conditioner. The refrigerant pipe also plays a great role. If you want the air conditioner to play a better role, the role of the refrigerant pipe is inevitable.
