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 vapo
r
izes 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.
