Recently is the peak season of home decoration, the author"s little partner asked the author, air conditioning installation fees? In fact, air-conditioning installation does not charge, but the author needs to remind the purchase of air-conditioning partners, if the installation of air-conditioning, air-conditioning copper pipe, more than the fixed length provided by the merchant, then the small partners have to pay their own pockets. Speaking of lengthening copper tubes, is it necessary to supplement refrigerant for air conditioning after lengthening copper tubes? Today I"ll give you a brief explanation of what happened after the air conditioner lengthened the copper pipe.

How many meters does the air conditioner need refrigerant after lengthening the connecting pipeline?

Answer:

According to the air-conditioning installation or maintenance process (national standards or industry related standards), refrigerants should be supplemented in time when the connecting pipes of indoor and outdoor units in air-conditioning installation exceed the standard length of more than 5 meters. According to different pipeline specifications or air conditioning models with different refrigeration capacity, electronic scales are used to quantitatively add refrigerants to ensure air conditioning performance (refrigeration and heating effect), otherwise, if refrigerants are not added in time after the air conditioning lengthens the pipeline, the refrigeration or heating operation pressure of air conditioning will be low, which will affect the performance all the time.

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

Answer:

The standard length of connecting pipes of household split room air conditioners shall be 5 meters according to the requirements of industry or national standards. One (refrigeration capacity: 2300W) to five (refrigeration capacity: 12500W-13000W), in the actual installation process, should be as far as possible controlled within 5 meters. After exceeding the standard length of 5 meters, refrigerants should be added according to the specifications of connecting pipes. The refrigerants for different pipes are as follows: 16 g/9.52 mm pipes per meter, 16 g/12.70 mm pipes per meter and 18 g/15.88 mm pipes per meter when exceeding the standard length of 5 meters. To ensure air conditioning performance.
