Nowadays, in view of the small amount of cold water output of industrial chillers, the failure of the chiller itself and the lack of load, a preliminary judgment can be made by observing the operating current of the industrial chiller. The heat exchange effect may not be good, for example, through Observe that the size of the heat exchange tube is too large to affect the heat transfer temperature difference between the heat transfer temperature of the refrigerator and the evaporation temperature. When the water flow is too large, how to stabilize the cooling effect of the industrial chiller?
First, check the compressor on time
The compressor is the "heart" of an industrial chiller, and its quality directly affects the stability of the chiller. If the compressor cannot be maintained, the cost will be relatively high, especially for high-precision screw compressors. If you hear the abnormal sound of the compressor etc., be sure to contact the manufacturer's professional technicians to determine the cause and repair it.
The second point is to regularly clean the condenser and evaporator
Condenser and evaporator are important parts of industrial coolers. The cooling water of the water-cooled condenser is an open loop. The tap water is recycled in the cooling tower. Impurities are easily decomposed and accumulated in the pipeline, which affects the heat transfer effect. Excess scale reduces the cooling water. Therefore, it is best to clean it at least once a year to remove scale from the pipes and treat tap water.
At the same time, the safety valve should be checked regularly. The condenser and evaporator of the industrial chiller are pressure vessels. According to regulations, the safety valve should be installed on the condenser body at the high-pressure end of the condenser. When the unit is in an abnormal working environment, The overflow valve automatically overflows to prevent possible harm to the human body under high pressure.
