What is the function of the air conditioner branch pipe?

The main function of the air conditioner branch pipe is to divert the refrigerant to each indoor unit, ensuring that each indoor unit can get the right amount of refrigerant, thereby achieving a uniform cooling effect. ‌

The air conditioner branch pipe, also known as the branch pipe, is an accessory for the VRV system (variable refrigerant volume air conditioning system). It is mainly used in the central air conditioning multi-split installation system, and plays a diversion role by diverting the refrigerant in the pipeline to each indoor unit. The branch pipe has a single input but multiple outputs, which ensures that the refrigerant can be evenly distributed to each indoor unit, thereby achieving balanced and efficient operation of the entire air conditioning system. ‌

Specifically, the branch pipe is divided into two types: gas pipe and liquid pipe. The diameter of the gas pipe is usually thicker than that of the liquid pipe. During the installation process, the selection of the branch pipe is determined according to the capacity of the indoor unit connected to each branch pipe, ensuring that each indoor unit can get the right amount of refrigerant.

Before installation, check whether the diameter of the copper pipe is consistent with the diameter of the central air-conditioning branch pipe. If the diameter of the copper pipe at the installation site is different from the diameter of the central air-conditioning branch pipe, use a cutting knife to cut off the different parts. Note: choose to cut at the same diameter.

When installing the central air conditioner branch pipe, try to place it vertically or horizontally. When placed horizontally, the inclination should be within ±15°. After placing it correctly, fill it with nitrogen for welding.

Flushing is to use ammonia pressure to remove impurities in the pipe. (Mainly dust, moisture, oxides caused by joints, etc.)For the central air conditioner branch pipe multi-way system, each pipe is labeled so that the branched connecting pipe and the indoor unit correspond to each other to prevent wrong connection.‌
