How to prevent the compression ratio of cryo chiller from being too high?
1. It should be considered to choose appropriate refrigerant to control the compression ratio of industrial chillers.
2. Industrial chillers should be checked for blockages. If there are blockages, it is recommended to replace the filter to prevent the generation of impurities and prevent pipeline and valve blockages. Another issue is that insufficient refrigerant leads to suction pressure, and high suction pressure can lead to problems such as high compression ratio and exhaust temperature.
3. It is also possible to perform separate additional cooling on the compressor, which can solve the problem of high exhaust pressure and temperature caused by high compression ratio in industrial chillers.
How to control the refrigeration compression ratio of a refrigerator?
Control the evaporator outlet temperature: By controlling the evaporator outlet temperature, the temperature and pressure of the refrigerant can be controlled, thereby controlling the refrigeration compression ratio of the refrigerator.
Adjusting the refrigerant flow rate: By adjusting the refrigerant flow rate, the pressure and temperature of the refrigerant in the evaporator and condenser can be controlled, thereby controlling the refrigeration compression ratio of the refrigerator.
Installing a throttling device: By installing a throttling device, the refrigerant flow can be controlled, thereby controlling the refrigeration compression ratio of the refrigerator.
Protective measures during operation of chillers
Regularly check the compressor: Regularly check the operating status and compression ratio of the compressor, and promptly handle any problems found to avoid compressor failures caused by high compression ratios.
Regular refrigerant replacement: Regularly replace the refrigerant to avoid refrigerant aging and pollution, which can affect the refrigeration effect and operating quality of the chiller.
Installation of pressure protection device: By installing a pressure protection device, the pressure changes in the chiller can be monitored. When the pressure is abnormal, it automatically shuts down to avoid damage to the chiller and the occurrence of personnel safety accidents.
Regular cleaning and maintenance of condensers and evaporators: Regularly clean and maintain condensers and evaporators to ensure their surfaces are clean, capable of sufficient heat transfer, and to avoid malfunctions caused by excessively high refrigeration compression ratios of the refrigerator.
