Air-cooled screw chiller unit
Air-cooled screw chiller

The air-cooled screw chiller mainly uses air as the cooling source, especially in resource scarce areas such as northwest or northeast China, and large units specially designed for water scarce countries or regions abroad. Because its key component - the compressor adopts a screw type, it is named an air-cooled screw chiller. The unit is in the state of gas refrigerant coming out of the evaporator; After adiabatic compression by the compressor, it becomes a high-temperature and high-pressure state. The compressed gas refrigerant is cooled and condensed at equal pressure in the condenser. After condensation, it changes into a liquid refrigerant, which then expands to low pressure through a throttle valve and becomes a gas-liquid mixture. The liquid refrigerant under low temperature and low pressure absorbs the heat of the cooled substance in the evaporator and becomes a gaseous refrigerant again. The gaseous refrigerant enters the compressor again through the pipeline and begins a new cycle. These are the four processes of the freezing cycle. It is also the main working principle of screw chillers.
