What's the effect of Gree air conditioner plus 4-meter extension pipe on refrigeration? Nanchang air-condition maintenance

Lengthening the air conditioner by 4 meters will affect the cooling effect. When the connecting pipes of indoor and outdoor units of air conditioner installation exceed the standard length of more than 5 meters, the refrigerant should be replenished in time. Solution: 1, Freon leakage will seriously affect the life and refrigeration quality of air conditioners. Soapy water can be used for testing. When the refrigeration performance of the air conditioner decreases and the filter screen and condensate water are normal, it is suspected that Freon is leaking. 2. When cooling, check whether the high-pressure pipe is frosted. If the leakage is serious, the frost will spread to the radiator of the condenser of the external machine. If the air conditioner has not been moved, leakage usually occurs at the connection port or solder joint. After the power is cut off, just open the cover, remove the air-conditioning filter screen and clean it with air-conditioning cleaner. Precautions for air conditioning pipeline lengthening 1. The air conditioning pipeline can be lengthened, but if it is too long, it will have a certain impact on the refrigeration effect, and the working frequency of the compressor will increase, so the service life will also be reduced. 2. When the pipeline is long, the pipeline must be emptied and refrigerant must be added to the balance. The insulation of the pipeline must be done well. This pipe is too long. If the heat preservation work is not done well, it will seriously affect the refrigeration effect. Generally speaking, the cooling effect will be reduced by 3% for every additional meter. 3. The longer the copper pipe connecting the indoor unit and outdoor unit of split air conditioner, the greater the refrigerant resistance generated by the pipe, the lower the suction pressure and evaporation pressure of the corresponding air conditioner compressor, the smaller the compressor capacity output and the worse the air conditioning capacity.
