Function
q The compressor circulates the refrigerant and
compresses the gaseous refrigerant from the
evaporator into a misty refrigerant at high pres-
sure and high temperature so that it will be easily
regenerated (liquefied) at the normal tempera-
ture.
q Calling into account of the evaporator tempera-
ture and refrigerant pressure, the air conditioner
controller activates magnetic clutch (2) built in
the compressor.
q When the magnetic clutch is engaged, the power
of the engine rotates the compressor shaft along
with pulley (1) to drive the compressor.
