Principle of Refrigeration System

The principle of compression refrigeration consists of “compression”, “condensation”, “throttling” and
“vaporization”. The compression is undertaken by compressor, the condensation is completed by
condenser, the throttling valve is executed by capillary and the vaporization is implemented by
evaporator. When the coolant is circulating in the closed refrigeration system, the compressor sucks
coolant, which has absorbs heat in evaporator, the coolant becomes a high pressure and high
temperature gas. In condenser, it dissipates heat in air, while the coolant is re-liquefied and throttled in
capillary and then enters into evaporator with low pressure. The liquefied coolant quickly boils and
vaporizes into gas when the pressure suddenly drops. Meanwhile, it absorbs heat inside the
refrigerator. And the compressor sucks the low pressure and low temperature gaseous
coolant,……….It is circulating in this way up to realization of intended refrigeration.
