The working principle of the air-cooled screw chiller mainly includes the following steps:

Compression system: The unit contains a compressor inside, which compresses low-pressure gas into high-pressure gas and pushes it into the condenser.

Condensation system: The high-pressure gas flows through the condenser, dissipates heat through the radiator, and is cooled to become a high-pressure liquid refrigerant.

Expansion system: The high-pressure liquid refrigerant enters the evaporator through the expansion valve. At this time, the liquid refrigerant will become low-temperature steam due to the sudden decompression, absorbing the surrounding heat to cool the air or chilled water.

Evaporation system: The low-temperature steam returns to the compressor and is recompressed into high-pressure gas in a cyclic manner, and the process continues to circulate, thereby achieving the cooling effect.

In addition, the air-cooled screw chiller also involves the chilled water circulation and the heat dissipation air process:
Chiller water circulation: After the chilled water absorbs heat from the evaporator, the temperature is reduced, and then it is sent to the user system for refrigeration. In the user system, the chilled water transfers heat to the object or space that needs to be refrigerated, and then returns to the evaporator to be cooled again, forming a closed-loop cycle.
Cooling air: The unit dissipates heat through fans and heat exchangers, absorbing air from the natural environment and sending it to the radiator of the condenser. The high-temperature refrigerant in the radiator transfers heat to the air, raising the air temperature, and then continuously inhales new air to dissipate heat, thereby maintaining the low temperature state of the condenser.
Compared with other types of chillers, the advantage of air-cooled screw chillers is that they do not require additional cooling water sources and are more convenient to use. However, due to the high noise of the unit itself, it usually needs to be installed in a closed machine room to reduce the impact of noise on the surrounding environment.

Compressor features:

•New screw type compressor with 20%-30% higher in efficiency.
 

•Cooling capacity control available at four steps (100%-75%-50%-25%), three steps (100%-66%-33%) or no steps control system.

•High efficiency, low noise and vibration, easy to install.

•Environmental protection refrigerant R134a, R407c available.

Control operation system:

•SIEMENS PLC program control system, human-computer interface with big LED touch panel, running state displaying in multi-language, and self-diagnosis for easy operation and supervision.

•Extended industrial interface, convenient for being computer monitor via network.

Completely safety protection function:

•Multi-safety protection by high and low pressure, compressor overheating, overloading, over temperature, flow switch, phase sequence, phase-missing, exhaust overheating and anti-freezing.
