What causes frost in industrial chillers

1. Lack of refrigerant.

When the refrigerant is lacking, the evaporating temperature of the chiller will drop. When the evaporating temperature of the chiller drops below zero, the fins of the evaporator will be frosted, which will affect the ventilation effect after a layer of frost. , The refrigerant flows into the pipes and compressors again after the refrigerant is not completely evaporated, and because of this, the chiller will be frosted;

2. Филтер је блокиран.

The clogging of the filter will also lead to the reduction of refrigerant, and even lower the evaporation temperature of the chiller, which will result in frost;

3. The expansion valve of the chiller becomes smaller or even blocked;

4. The ducts of the chiller are not well ventilated;

5. The air filter, condenser pipe, and evaporator of the chiller have garbage and dust accumulation;

The above five points are about why the low pressure part of the industrial chiller compressor will be frosted
