Working Principle
The screw compressor in a water cooled screw chiller compresses refrigerant gas, which is then condensed into a liquid state in a condenser. The liquid refrigerant is expanded through a throttling valve into a low-pressure, gas-liquid mixture. In the evaporator, the liquid refrigerant absorbs heat from the water or other substance being cooled, turning back into a gaseous state. This gaseous refrigerant is then recirculated back to the compressor, completing the refrigeration cycle.
Efficiency and Performance:
Water cooled screw chillers are known for their high efficiency, particularly in medium to large-scale applications. The screw compressor design offers low noise, low vibration, and high compression efficiency. Additionally, the heat exchanger design, often using a patented double flow equalizer and asymmetric arrangement technology, can effectively improve heat transfer efficiency.
