Several tips for improving the efficiency of chillers

1. Ensure the cleanliness of the condenser pipeline
The condenser is one of the important accessories of the chiller. During the use of the chiller, the heat exchange tube of the condenser will produce sediment, mud, various impurities and other dirt. We need to use distilled water and purified water to inject water into the tank. Ordinary water sources can cause the condenser to experience the conditions described above. This leads to an increase in the condensation temperature of the condenser, while also increasing the power consumption of the compressor. Once there is a problem of dirty heat exchange tubes in the condenser of the chiller, it is necessary to clean them in a timely manner and, if necessary, perform chemical cleaning.

2. Check if the device is leaking
Regular leakage testing can be conducted on the compressor. The chiller should be kept running dry. There is residual moisture in the chiller, which may also generate acidic substances that can corrode the motor and bearings, leading to rusting of the casing, and so on. Leakage can also lead to insufficient refrigerant replenishment and other issues. If not handled in a timely manner, it may result in expensive maintenance costs.

3. Reduce the injection temperature of cooling water
The chiller is labeled with the minimum temperature of the cooling water inlet. The inlet temperature of cooling water is closely related to the energy consumption, condensation pressure, and temperature of the chiller. At the same time as lowering the temperature of the cooling water, the temperature and pressure of the condenser are correspondingly reduced. Many water circulation systems add valves in their design to control the cooling water temperature to the specified target by adjusting the valves. This can reduce the condensation load.

4. Adopting frequency conversion technology
The use of frequency conversion technology can enable the chiller to automatically adjust its operating speed under different load conditions, achieve optimal matching, and thus reduce energy consumption.

5. Maintain daily logs
Employees should adhere to recording accurate and detailed chiller work logs every day. Reading data every day can generate accurate trend reports, helping us maintain them in a timely manner when encountering problems.

The above are the points discussed today about how to improve the operating efficiency of chillers. We should also pay more attention when using them in daily life, so as to ensure the best user experience and smooth operation of the equipment in production.
