Tips on Air Conditioning Extension Tube

Many friends know that if the air conditioner is installed, there will be an extra charge, and this fee does not seem to be low, but you don’t know that after the air conditioner connecting pipe is extended to a certain distance, you need to add enough refrigerant To make the air conditioner run strongly, are you completely dumbfounded? Today, I will give you a brief explanation of those things after the air conditioner is lengthened with copper pipes.

　　 How many meters do I need to add refrigerant after the air conditioner is lengthened to connect the pipeline?

　　 According to the air-conditioning installation or maintenance process (national standards or industry-related standards), when the connecting pipes between the indoor and outdoor units of the air-conditioning installation exceed the standard length of more than 5 meters, the refrigerant should be added in time. According to different piping specifications or air conditioning models with different cooling capacities, an electronic scale is used to add refrigerant quantitatively to ensure the performance of the air conditioning (cooling and heating effect). Otherwise, the air conditioning will be in place when the air conditioning is extended by the pipeline if the refrigerant is not added in time Low cooling or heating operating pressure has always affected performance.

　　 What is the standard length of the connecting pipe for the indoor and outdoor units of the household split air conditioner?

　　The standard length of the connecting pipe of the household split room air conditioner is 5 meters in accordance with the requirements of the industry or national standards. 1 horse (cooling capacity: 2300W) to 5 horses (cooling capacity: 12500W-13000W), in the actual installation process, should try to control within 5 meters. When the length exceeds the standard 5 meters, the additional refrigerant should be added according to the operating process requirements and the specifications of the connecting pipes. The additional refrigerants for different air pipes are as follows: when exceeding each meter, 16g /Φ9.52mm air pipe per meter, 16g /Φ12. 70mm trachea per meter, 18g/Φ15.88mm trachea per meter. To ensure air conditioning performance.
