2.1.2 Working Principle of SICC-W Double Unit Series
The SICC-W water-cooled central water chiller is mainly made up of four
components which are compressor, condenser, thermostatic expansion valve
and evaporator. It uses single stage vapor compression refrigeration system,
and takes the advantage of the mechanism of transformation between gas and
liquid status for absorbing and releasing heat by using of refrigerant to achieve
the effectiveness of refrigeration.
