The chiller unit is a device used for refrigeration and cooling, widely applied in various fields such as industry, commerce, and households. To ensure the chiller unit operates normally and achieves optimal performance, the following is a detailed operating procedure.

1. Preparations Before Starting

1. Check whether the power supply of the chiller unit is connected properly and ensure the power supply is stable.

2. Check whether the cooling water and chilled water systems are unobstructed and ensure there are no leaks.

3. Check the status of each valve to ensure they are in the correct working position.

2. Starting Operation

1. Turn on the power and start the chiller unit.

2. Wait for the unit's self-check to complete and observe whether the indicators on the control panel are normal.

3. Gradually adjust the flow of cooling water and chilled water to ensure the unit is in normal working condition.

3. Operation Monitoring

1. Regularly check the operating status of the unit, including parameters such as temperature, pressure, and flow.

2. Listen to the operating sounds of the unit and check for any abnormal noises.

3. Regularly check the vibration of the unit to ensure stable operation.

4. Adjustments and Maintenance

1. Adjust the temperature, pressure, and other parameters of the unit according to actual needs to ensure optimal refrigeration effect.

2. Regularly check the cooling water and chilled water systems of the unit, cleaning scale and impurities.

3. Regularly check the electrical system of the unit to ensure the normal operation of electrical components.

4. Regularly maintain the unit, including replacing filters and checking the refrigerant charge.

5. Shutdown Operation

1. Turn off the power and stop the operation of the chiller unit.

2. Shut down the cooling water and chilled water systems.

3. Clean the surface of the unit and the surrounding environment to keep it tidy.

6. Precautions

1. Operators must have the corresponding professional knowledge and operational experience, and be familiar with the performance characteristics of the unit.

2. During operation, it is strictly forbidden to touch high-temperature parts to avoid burns.

3. Regularly check for leaks in the unit; if abnormalities are found, they should be dealt with promptly.

4. During operation, if any abnormal noise, vibration, or odor is detected, the unit should be stopped immediately for inspection.

5. The operation of the chiller unit should strictly adhere to relevant safety regulations and operating procedures.

By following the above operating procedures, the normal operation and long-term use of the chiller unit can be ensured. In actual operation, operators should make adjustments and maintenance according to specific conditions to ensure the safe and efficient operation of the unit.
