How many meters of air conditioning to lengthen copper tube to add refrigerant?

        air conditioning, how many meters long copper tube need to add refrigerant? (
Air conditioning pipeline lengthened after more than how many meters need to add refrigerant?
        answer: according to air conditioning installation or maintenance process (national standards or industry related standards): when the air conditioning to install indoor and outdoor machine connection pipe exceeds the standard length of 5 meters, should be added to the refrigerant. According to different pipe size or different refrigeration capacity of the air conditioning model, the use of electronic scales to add refrigerant, to ensure the performance of air-conditioning (refrigeration system heat effect), otherwise, when the air conditioning is not in time to add refrigerant will be in place air conditioning refrigeration or heating operation pressure is low, has been affecting performance.
Connecting pipe length is the number of meters standard household type indoor machine of air conditioner?
The standard length of the connecting line of the air conditioner in the home split type room air conditioner shall, in accordance with the requirements of the industry or national standards, is 5 meters. 1 (refrigeration capacity: 2300W) to 5 HP (refrigeration quantity: 12500W-13000W), in the actual installation process, should be controlled within 5 meters. After more than standard 5 metres in length, should according to process requirements, according to the connection pipeline of tracheal specifications reference additional refrigerant and different tracheal additional refrigerant as follows: beyond every meters, 16g/Φ 9.52mm tracheal per meter, 16g/Φ tracheal 12.70mm per meter, 18g/Φ 15.88mm tracheal per meter. To ensure the air conditioning performance.
