VI. COOLING CIRCULATION AND MAIN COMPONENT FUNCTION
FUNCTION OF EACH COMPONENT
1.
COMPRESSOR
The function is to compress gaseous make temperature and pressure high.
2.
CONDENSOR
The function is to lower down the refrigerator temperature, so it is liquified with same pressure.
3.
PIPA MULLION DRYER
4. DRYER
5. CAPILARY
6. EVAPORATOR
7. SUCTION PIPE
The function is to pass the low pressure gas to
compressor.
The function is to prevent from sweating.
It is contain silica gel and soft filter. The dryer
collect moisture and dust in the refrigerant cycle, so
that capillary tube will not clogged up.
The function is to pass the low pressure of liquid
refrigerant.
The function is to reduce the pressure of liquid
refrigerant until the liquid vaporate, and to the heat
in store room as cooling effect or vaporation.
