Principle of refrigeration system and electric circuit diagram

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 the
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.
