The refrigeration systems of vapor compression chiller generally consist of the compressor, the condenser, the throttling element, and the evaporator. The compressor compresses the refrigerant gas, outputs high-temperature and high-pressure refrigerant, and liquefies it into high-pressure and normal temperature fluid through the condenser (cooling water or air). Then, the fluid enters the throttling element (expansion valve or capillary tube, etc.) to reduce the pressure and temperature of the refrigerant simultaneously. The throttled refrigerant enters the evaporator and absorbs the heat of the cooled object. Afterwards, the refrigerant is sucked in and compressed by the compressor to circulate. The refrigerant is repeatedly compressed, condensed, expanded, and evaporated in the refrigeration system, continue to absorb heat and vaporize at the evaporator for cooling.

Accurate temperature control; reliable & stable; rapid cooling; environment friendly
