PRINCIPLE OF REFRIGERATION SYSTEM
The principle of compression refrigeration consists of "Compression", "Condensa-
tion", "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 consider, it dissipates heat in air, while the coolant is reliquaries
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.
