How to check the high and low pressure of the chiller kompressor

1. By visual inspection: when the compressor is in normal operation, the vibration amplitude of the compressor will not be too large. The weak vibration plus a certain and stable swing amplitude is the normal operation state of the compressor. At this time , The high and low pressure problems of the compressor of the refrigerator will basically not exist, or it will not be too serious.

2. You can also check the temperature of the inlet and outlet water of the refrigerator: if the high and low pressure of the refrigerator are normal, not only the operation of the compressor tends to be normal, but the cooling efficiency and effect of the entire refrigerator system will also be normal, so the outlet water temperature even includes The inlet water temperature can be normalized. By checking the temperature of the inlet and outlet water of the refrigerator, it can be verified to a certain extent whether the high and low pressure of the refrigerator are normal.

3. The operator of the refrigerator can also check whether the high and low pressure of the refrigerator are normal by checking the operation status of the compressor. He can judge by listening to its sound: when the compressor of the refrigerator is running normally, that is, the high and low pressure are normal. Below, the operating sound of the refrigerator compressor is normal, and experienced refrigerator operators can hear clues.
