​Common Fault Analysis and Solutions of Chillers

The analysis and solution of the chiller failure depends on the specific failure situation. If the chiller fails, it must be dealt with in a professional way in time to ensure the safe and stable operation of the chiller; and regularly check whether the various parts of the chiller are worn or damaged. If it is damaged, it should be replaced in time. In addition, when purchasing chillers, enterprises should reasonably match the chillers according to production needs, so as to better use Jiusheng chillers and achieve the effect of reducing the use cost of enterprises.

The following are some common chiller failures and corresponding solutions:

1. Poor refrigeration effect/decreased refrigeration capacity: analysis may be caused by refrigerant leakage, serious dirt on the condenser, frosting on the evaporator, compressor failure, etc.

  Solution: Check and repair refrigerant leaks, clean condenser, defrost evaporator, check and repair or replace compressor.

2. Excessive compressor noise/vibration: analysis may be caused by internal compressor failure, unstable installation, abnormal cooling fan, etc.

  Solution: Check and repair or replace the compressor, adjust the installation stability, check and repair or replace the cooling fan.

3. The chiller cannot be started: analysis may be due to power failure, control circuit failure, pressure switch failure and other reasons.

  Solution: Check the power supply, check the control circuit, check and adjust the pressure switch.

4. Water leakage of chiller: analysis may be caused by loose connection of cooling water pipes, water leakage of condenser, water leakage of evaporator, etc.

  Solution: Check and tighten the cooling water pipe connection, repair the leaking part of the condenser, repair or replace the leaking evaporator.

5. Abnormal cooling water temperature: Analysis may be caused by cooling water pump failure, water valve not working, unstable water flow, etc.

  Solution: Check the cooling water pump, repair or replace the non-working water valve, check and adjust the water flow.

Chiller fault analysis and solutions are a comprehensive task. For the above faults and solutions, it is recommended to find professional chiller maintenance personnel to carry out detailed fault diagnosis and repair work to ensure safety and reliability. At the same time, regular maintenance is also very important to prevent failures and prolong the life of equipment.
