Common Faults And Solutions For Chiller Compressors
May 12, 2025
As a leading enterprise in the industry, Hengde Company relies on the Industrial chiller to play a crucial role in various industrial production processes. It can precisely control the temperature and ensure the stable operation of production equipment, which is a key link in ensuring production efficiency and product quality. However, during long - term use, the compressor of the industrial chiller may issue some fault alarms, which not only affect the normal operation of the equipment but may also lead to production stagnation. To help you solve problems quickly and effectively, the following details the common high pressure alarm and low pressure alarm faults of the Industrial chiller compressors of Hengde Company and the corresponding solutions.
High - Pressure Alarm of Industrial chiller Compressor
1. The condenser is dirty and blocked.
Solution: Clean the condenser, keep the air temperature below 40°C / keep the cooling water below 35°C.
2. The high - pressure switch trips.
Solution: Press the reset button of the high - pressure switch and restart the compressor.
3. Over - charging of refrigerant.
Solution: Check whether the refrigerant charging amount is excessive.
4. Cooling water pump failure.
Solution: Repair or replace the water pump.
Low - Pressure Alarm of Industrial chiller Compressor
1. Insufficient refrigerant or refrigerant system leakage.
Solution: Check whether the system lacks refrigerant or whether there is leakage in the system pipelines.
2. Insufficient water flow or system shortage causes the evaporator to freeze.
Solution: Check whether the water tank is short of water and whether the valve is fully opened. If the evaporator freezes, drain the water completely and then add warm water to melt it. Do not knock the ice with hard objects, as piercing the copper tube will damage the compressor!
3. Chilled water pump failure or pipeline blockage.
Solution: Check the chilled water pump and pipeline system.
