Maintenance and servicing of chillers is a key step to ensure the normal operation of the equipment and extend its lifespan. Here are some basic maintenance suggestions:

1. Daily Maintenance:

1. Cleaning: Regularly clean the surface of the chiller and the surrounding environment to keep the equipment clean and tidy.

2. Check Operating Temperature: Check the operating temperature of the equipment to ensure it is within the normal range.

3. Leak Check: Regularly check for leaks in the refrigerant and cooling water.

2. Regular Maintenance:

1. Replace Filters: Regularly replace the filters at the inlet and outlet of the cooling water to ensure smooth water flow.

2. Check Refrigerant: Check if the refrigerant level is sufficient, and replenish it in a timely manner if necessary.

3. Check Electrical Components: Check if the motor, cables, junction boxes, and other electrical components are functioning normally to ensure safe operation of the equipment.

4. Check Fasteners: Check if the fasteners of various components of the equipment are loose, and tighten them promptly if they are.

3. Semi-Annual Maintenance:

1. Check Radiator: Clean the dirt on the surface of the radiator to ensure good heat dissipation performance.

2. Check Compressor: Check the operating condition of the compressor and address any abnormalities promptly.

3. Check Refrigeration Oil: Check the quality and quantity of the refrigeration oil, and replace or replenish it if necessary.

4. Annual Maintenance:

1. Comprehensive Inspection: Conduct a comprehensive inspection of the chiller, including electrical, mechanical, and refrigeration components.

2. Clean Condenser: Clean the condenser to ensure its heat dissipation performance.

3. Replace Aging Parts: Replace aging parts such as seals and hoses.

4. System Calibration: Calibrate the equipment system to ensure its operational accuracy and stability.

5. Long-Term Shutdown Maintenance:

1. Clean Equipment: Thoroughly clean the equipment to ensure there is no dust or dirt.

2. Power Protection: Disconnect the power supply and perform protective measures for the equipment.

3. Regular Checks: Even equipment that is not in use for a long time should be checked regularly to ensure it is in good condition.

When performing maintenance and servicing of chillers, be sure to follow the operating guidelines and recommendations provided by the equipment manufacturer. If unsure how to proceed, it is advisable to seek help from professional maintenance personnel. Proper maintenance not only ensures the normal operation of the chiller but also improves the efficiency and lifespan of the equipment.
