How To Solve The Problem Of Chiller Malfunction

The compressor operates smoothly, with a large temperature difference between suction and exhaust, and a low temperature rise in the body; The condensation temperature is high, and the temperature difference between the inlet and outlet of the cooling water is large; If there is no refrigerant leakage at the joints of each pipeline, there should be no oil contamination, etc; Any manifestation opposite to the above situation indicates the presence of fault factors in the corresponding area.
It is also possible to check whether the overall sound during the operation of the chiller unit conforms to the normal working sound pattern. In addition, it is also necessary to check for abnormal sounds in the electromagnetic valves, throttle valves, and other equipment of the compressor lubrication oil pump and chiller unit systems.
It can be determined from these aspects that the chiller is malfunctioning. For example, when the compressor emits a slight "chug, chug, chug" sound or a continuous and even light "buzzing" sound during operation, it indicates that the compressor is operating normally; If you hear a "dong, dong, dong" sound or a slow rotating sound of the impeller, or an abnormal vibration sound, it indicates that the compressor has experienced liquid shock or end vibration.
When a chiller malfunction occurs, comprehensive analysis should be conducted on the operating data and materials of the chiller unit obtained from relevant indicating instruments and methods such as observation, listening, and touch, to identify the basic cause of the malfunction and consider what emergency measures should be taken.
