In the application of industrial refrigeration, water chillers are used in combination with production and processing equipment, so their operation time is longer. If customers lack professional maintenance and routine equipment maintenance for water chillers in their daily life, and there is little periodic replacement of consumable parts and consumable parts, even from the moment the equipment is installed, the frequency of water chiller failure will be very high, so here to teach you some about chillers troubleshooting repair methods, such as chillers if there is a high side pressure of low-pressure situation, the possible reasons for how to judge the analysis. If the temperature of the chilled water on the cooling side of the chiller is too high, it may be hot water above 40 °C, then the refrigerant low pressure value of the chiller will be very high, the refrigerant low pressure value of chillers will gradually decrease after the freezing water temperature will slowly decrease. If the refrigerant charge of chillers is increased, the refrigerant high pressure value and low pressure value of chillers will be on the high side. If the capillaries or expansion valves of the throttling devices of industrial chillers are damaged and the throttling depressurization of refrigerants fails, then the refrigerant low pressure value of industrial chillers will be higher, there is no obvious change in the value of high and low pressure, that is, there is no compression ratio, and the value of high and low pressure is similar to that of industrial water chillers when they are shut down, it is possible that the compression component in the compressor is damaged, the refrigeration compressor can not be compressed.
