What are the hazards of leaving air in the refrigeration system of industrial chillers?

Industrial chillers are a type of refrigeration equipment that compresses refrigerant to reduce the temperature of water and provide the necessary cooling water for industrial production. After a period of use, industrial chillers may have air in their refrigeration system due to corrosion of internal components, decomposition of lubricating oil and refrigerant, and air leakage during operation. If there is air left in the refrigeration system of industrial chillers, What harm will there be?

1. Causes the condensation pressure of the industrial chiller to increase
In the condenser of an industrial chiller, total pressure=air pressure+refrigerant pressure. When there is air in the refrigeration system of an industrial chiller, the more air it produces, the greater the air pressure it produces, resulting in an increase in the total pressure of the condenser.

2. Reduce the heat transfer efficiency of the condenser
Due to the presence of air, the gas layer formed on the heat transfer surface of the industrial chiller condenser plays a role in increasing thermal resistance, which can lead to a decrease in the heat transfer efficiency of the condenser.

3. Corrosive pipelines and other equipment
Due to air entering the refrigeration system of the industrial chiller, the water content of the refrigeration system increases, which may corrode the pipes and other equipment of the industrial chiller.

4. Causes a decrease in cooling capacity
Accidental entry of air into the refrigeration system of an industrial chiller can lead to an increase in condensation pressure, resulting in a decrease in the cooling capacity of the chiller and an increase in its power consumption.

5. Accidental accidents are prone to occur
There is air in the refrigeration system of industrial chillers. When the exhaust temperature is high, encountering oil vapor can easily lead to accidents.

Therefore, we should try our best to avoid leaving air in the refrigeration system of the chiller. One method is to use high-quality sealing materials during system installation to ensure system sealing. The second is to regularly inspect and clean the system during use to remove impurities and air. The third is to use high-quality equipment and accessories to ensure the stability and stability of system operation.
