Causes of the problem of the low pressure side of the refrigerator compressor

1. Insufficient amount of refrigerant, this is more common, usually caused by leakage.

2. Insufficient chilled water causes the evaporator to work abnormally, which in turn leads to problems with suction pressure and suction temperature at the low-pressure side of the compressor of the refrigerator.

3. The expansion valve cannot be opened and closed normally, or the thermal expansion valve fails to cause opening and closing angle problems.
