Safety protection method of chiller compressor

Several safety protection methods for compressors in industrial chillers In industrial chillers, the quality of the compressor determines whether the working efficiency of the chiller is good. At the same time, the compressor also plays an important role in the after-sales maintenance of the chiller. Once a failure occurs, it will improve the company's maintenance of the chiller. Increase in costs. In order to reduce the maintenance cost of the chiller, we recommend the following 4 methods to protect the compressor of the chiller.

The role of lubricating oil

The role of lubricating oil 1) A dynamic seal is formed between the screw and the compression chamber and the male and female screws to reduce the leakage of refrigerant from the high-pressure side to the low-pressure side during the compression process.

The role of refrigerant in the air-cooled chiller

The refrigerant itself circulates continuously in the refrigeration system, and then realizes refrigeration through its own state changes. The refrigerant absorbs the heat of the cooling medium in the evaporator and vaporizes, and transfers the heat to the surrounding air or water in the condenser to condense.

Solution to water leakage of fan coil ceiling

The fan-coil system is supplied with chilled water by the chiller, and the water temperature is usually only about 8°C. Therefore, the chilled water supply and return pipes, condenser pipes and condensate trays are all relatively low in temperature.
