For household split wall mounted or cabinet type air conditioners, the maximum length of the connecting pipe between indoor and outdoor units is generally not more than 12 meters, and the length of the connecting pipe between indoor and outdoor units of medium-sized split air conditioners is generally not allowed to exceed 20 meters or 40 meters. The allowable length of connecting pipes for internal and external units of large and medium-sized split air conditioning units will be 100 meters or even longer.
For an air conditioning unit, when the length of the connecting pipe reaches a certain extent, the working conditions of the compressor become very bad, which is very detrimental to the safe operation of the compressor.
How far can the split air conditioner go
1~3 meters is the best!
The shorter the distance between indoor unit and outdoor unit of air conditioner, the better! The fewer transitions in the middle of the pipeline, the better, so that the cooling effect is better.
The minimum length of piping shall not be less than 1 meter. Generally, it is recommended to be within 3 meters, or 5 meters, or 10 meters.
When the pipe length is more than 5 meters, 40 grams of R22 shall be added for every additional 1 meter. (PS: R22 is a member of the Freon family. It is the most widely used medium and low temperature refrigerant today.)
Maximum allowable length of connecting pipe: cabinet machine: 15m, hanging machine: 10m. There is no maximum requirement, but the farther the distance is, the more fluorine and electricity will be consumed.
In addition, because the pipes transporting refrigerant are copper pipes, 90 degree bends should be reduced, or they will be easily crushed.
If the copper pipe is folded or broken, the air conditioner will not be cold
How far can the split air conditioner go
Generally, the length of one horse shall not exceed 6 meters, 9 meters for two, and 12 meters for three. The normal piping for the connection between the indoor unit and the outdoor unit of the split air conditioner is 4 meters, and the length of the pipe is not more than 15 meters under specific circumstances.
