The outdoor installation of air-cooled chillers make it easy to be affected by outdoor sunlight, and  the ventilation and the environment and space has a direct impact on the cooling effect of the chiller. The common failure and processing method are as follows:

(1) Frequent start and stop of the compressor: there may be too much or too little refrigerant, resulting in pressure protection switch action which is resulted from too high exhaust pressure or  too low suction pressure, and also poor water system circulation make sevaporator surface frost.

Method: When the refrigerant is too much, the extra can be released at the vent. If there is a shortage, check whether there are leaks of the fluorine and fill the refrigerant.

If the water circulation system is blocked or stored in the air, you should exhaust; if water circulation too small, utilize the open refrigeration water circulation system.

(2) Noisy compressor when running: check whether the expansion valve fails, the temperature package discharges the suction pipe from the compressor, which causes the liquid refrigerant return to the compressor. If it is damaged, it should be repaired, for example, if the compressor is damaged, it should be replaced.

(3) Poor refrigeration capacity: the cause of the poor refrigeration capacity may be the insufficient refrigerant and low evaporation temperature that makes the por cooling effect of the pipeline; poor heat dissipation of the condenser; too large the resistant of the water circulation system,etc..

The refrigerant pipe should be checked for leakage and fill the refrigerant after repairing.You should repair the insulation layer and Clean the condenser to check whether the fan is working properly as well as clean the pipe filter.
