Function of AC system
Compressor
The refrigerant arrives at the compressor from the
evaporator at low pressure and as a gas. It is
compressed in the compressor, which increases its
pressure and temperature. The warm, gaseous
refrigerant is then forced into the condenser.
Condenser
The hot, high pressure refrigerant is pumped by the
compressor into the condenser’s coiled tubes. The
coiled tubes are fitted with cooling flanges around which
air is circulated by the ventilation fan and the air
stream. As heat is always transferred from a warmer to
a cooler object, the hot refrigerant will transfer some of
its heat to the cooler air. The hot, gaseous refrigerant
will then lose some of it’s heat, start to condense and
thus become liquid.
Receiver Drier
The refrigerant is stored and dried in the
receiver drier reservoir.
The refrigerant enters receiver drier reservoir as a liquid
under high pressure and with high temperature. It
passes through the filter, where it is receiver drier and
any particles removed. The refrigerant is then
transported, as a liquid, to the expansion valve.
The system’s pressure monitor is located on the
receiver drier rservoir and is called the pressostat.
