OPERATING
PRINCIPLES
With
the air conditioning control
'ON'
and engine running, the compressor clutch
operates engaging the compressor. Low pressure vapour entering the compressor is
converted into high pressure vapour at the output and discharged into a condenser. The
vapour i s cooled i n the condenser changing into a liquid, from here i t flows into the
receiver-drier, where any foreign matter i s expelled.
A
sight glass following the receiver-drier provides a means of checking the system is f u l l
of refrigemnt and operating correctly. High pressure liquid enters the expansion valve
where it expands rapidly changing from high to low pressure liquid.
As
the refrigemnt
expands i n the evaporator i t begins to boil, absorbing heat from the core and cooling the
air passing through to the passenger compartment. The compressor draws off the low
pressure vapourised refrigerant completing the closed circuit and recyclirtg the refrigerant
passenger compartment
Conderser
The condenser i s located i n front of engine radiator.
Air
passes over the condenser
cooling fins, cooling the 'hot' high pressure refrigemnt vapour and condensing it into
