　　What is the reason for the overheating of compressors in water cooled industrial chiller?

　　The compressor is overloaded and operates with overcurrent, which may be caused by:

　　1) The cooling water temperature is too high and the refrigerant is overcharged;

　　2) The presence of non-condensable gases such as air in the refrigeration system leads to high compressor load, manifested as overcurrent and accompanied by high-voltage faults.

　　Electrical faults caused overcurrent operation of the compressor in the water-cooled industrial chiller unit, which may be caused by:

　　1. The three-phase power supply voltage is too low or the three-phase is unbalanced, resulting in excessive current or a phase current;

　　2. The AC contactor is damaged, causing contact erosion, resulting in excessive contact current or excessive current due to phase loss.

　　The overheat protection module SSM of the water-cooled industrial chiller unit is damp or damaged, the intermediate relay is damaged, and the contact is poor. This is manifested as overheating failure upon startup, and the compressor cannot start normally. If the unit electronic board malfunctions or communication malfunctions, it may also falsely report an overheating fault.

　　The placement of water-cooled industrial chillers is not ventilated, and there is no ventilation distance reserved for the inlet and outlet of the chiller.

　　If a compressor overheats during the use of a water-cooled industrial chiller, the causes can be identified from the above four aspects and targeted solutions can be provided.
