In the industrial refrigeration application, the chiller is used in conjunction with the production and processing equipment, so it runs for a long time. If the customer lacks professional maintenance and routine equipment maintenance for the chiller in the daily life, There is a periodic replacement of consumable parts, even if it is installed, no matter whether the power supply is turned on or off, the frequency of failure of the chiller will be very high. The possible reasons are as follows: 1. If the temperature of the chilled water of the medium to be cooled and cooled is too high when the chiller is turned on, it may be hot water above 40 °C, then the low pressure of the refrigerant of the chiller will be very high, with the chiller The cooling operation continues, and the chilled water temperature will gradually decrease, and the low pressure value of the refrigerant of the chiller will gradually decrease; 2. If the refrigerant charge of the chiller is added more, the high pressure value and low pressure value of the chiller will be higher; 3. If the capillary or expansion valve of the chiller throttling device is damaged, and the refrigerant throttling and depressurization failure occurs, the refrigerant low pressure value of the chiller will be higher; 4. If the high and low pressure values ​​do not change significantly when the chiller is turned on, that is, there is no compression ratio. When the high and low pressure values ​​of the chiller in the shutdown state are similar, this may be the damage of the compression components in the compressor. The refrigeration compressor cannot be compressed.
