Central air conditioning cleaning-how should the air conditioning evaporator be repaired?



I. Insufficient refrigerant The split air conditioner will leak or leak due to installation or long usage time. After the refrigerant in the refrigeration system is reduced, the evaporation pressure will be too low and the evaporator will freeze and freeze. In the front part of the evaporator, the troubleshooting method is to deal with the leaking part and add refrigerant to the fault.
Second, the compressor has been used for a long time. The compressor's compression efficiency is reduced or the compressor's gas distribution system is damaged, resulting in too low pressure and icing. The icing position is also in the front of the evaporator. The former can be ruled out with some refrigerant faults. If the fault persists The compressor must be replaced.
Third, there are too many refrigerants. Some air conditioners are refilled with refrigerant due to displacement, leakage, etc. Maintenance personnel improperly added more refrigerant, causing excessive refrigerant to flow to the evaporator and partially evaporate and freeze. This type of ice It is often connected to the back of the evaporator and around the compressor return pipe. If the excess refrigerant is released, the fault will be ruled out.% 0D% 0A Fourth, the dust in the air conditioner or the microorganisms generated by the evaporator will be used after a period of time. It accumulates on the evaporator and obstructs the air circulation and causes heat exchange. The evaporator temperature is too low and freezes. The freezing position is behind the evaporator. After the ice melts, flush the evaporator with water and use a soft bristle brush along the fins. Wet electrical parts. After cleaning, the fault will be eliminated.
