Specifications & Parameters

The air-cooled screw compressor is an industrial refrigeration equipment that uses a screw compressor. It achieves the refrigeration cycle through air cooling. Its core components include an efficient screw compressor, copper tube condenser and evaporator, and it features a small size, low noise and high energy efficiency. 




Working Principle

The air-cooled screw chiller operates based on the refrigeration cycle and consists of four key steps: 

Compression: The refrigerant enters the screw compressor and is compressed into a hot and high-pressure gas;

Condensation: The hot gas passes through the air-cooled radiator to release heat and turns into a liquid state;

Expansion: The liquid refrigerant passes through the expansion valve and is depressurized to a low-temperature and low-pressure state;

Evaporation: The low-temperature refrigerant absorbs heat (such as from cooling water) in the evaporator, evaporates and then re-enters the compressor cycle. 

Core feature

Efficient Energy Saving: Utilizing a twin-screw 5:6 toothed compressor, the energy efficiency ratio can reach 5.1 (in low-temperature conditions);

Stable and Reliable: Equipped with a double-layer oil separation system and multiple safety protections (such as high and low pressure protection, motor overheating protection);

Environmentally Friendly Adaptability: Supports environmentally friendly refrigerants like R22/R134a/R407c;

Intelligent Control: Equipped with a PLC system for remote monitoring and capacity adjustment (four-stage/stepless adjustment). 

Application scenarios

It is widely used in business hotels, large shopping malls, hospitals, industrial cooling, and low-temperature freezing, etc. It can ensure stable operation within an environmental temperature range of -10℃ to 45℃.
