The engine driven refrigerant compressor (2) sucks
in gaseous refrigerant from the suction accumulator
and compresses it. The temperature of the
refrigerant rises to a value between 70 °C and 110
°C. It passes to the condenser (1) under high
pressure.
At this point heat is drawn from the refrigerant by
the air being forced past the cooling fins. Because
of this heat loss, the refrigerant liquefies and leaves
the condenser.
A fixed orifice tube (6), which separates the
refrigerant at high pressure from that at low
pressure, is located between the condenser and
the evaporator (5). This fixed orifice tube slows
down the flow of the refrigerant from the compressor, so that pressure builds up in the
condenser.
After passing through the fixed orifice tube the
liquid refrigerant expands in the circuit to the
evaporator, where it becomes gaseous. This
causes heat to be extracted from the air coming
into the vehicle. The air cools down, and excess
moisture contained in it is condensed and is
drained off. The refrigerant coming from the
evaporator flows into the refrigerant accumulator
and is again sucked in by the refrigerant
compressor.
The system is protected by a high-pressure limiting
switch, in order to prevent damage by excessive
pressure (e.g. because of overfilling with
refrigerant). If the pressure exceeds the maximum

permitted, the high-pressure switch turns off the
refrigerant compressor.
The compressor on-off cycle is controlled by the
dual pressure switch depending on the pressure
in the refrigerant accumulator. The dual pressure
switch turns the refrigerant compressor off
permanently if the pressure falls below a permitted
value (e.g. if there is a leak).
Component Description
Air conditioning compressor
E100826
The special feature of a compressor with variable
swash plate is that the stroke of the pistons can
be varied by means of the variable swash plate.
The swash plate is mounted on a slide rail in the
axial direction.
The piston stroke and thus the delivery rate are
determined by means of the variable obliqueness
of the swash plate.
The obliqueness of the swash plate is dependent
upon the chamber pressure and thus on the
pressure conditions at the top and bottom of the
piston. This is supported by springs in front of and
behind the swash plate.
The chamber pressure is determined by the high
and low pressure applied to the control valve and
by a calibrated orifice bore. If the low pressure is
relatively high, the control valve is opened and the
chamber pressure is reduced.
If the low pressure is relatively low, the control
valve is closed and the chamber pressure is
increased. The force due to the chamber pressure
exerted on the piston bottom, is higher than the
sum of the force due to the low pressure on the
piston top and the spring force.
Pollen filter
E97720
The fresh air flowing into the vehicle through the
air inlet housing passes through a pollen filter which
is located on the left-hand side of the climate
control housing (LHD and RHD) and removes
pollen and dust particles measuring 0.003 mm or
more.
Control assembly, climate control -
vehicles with manual temperature control
E97721
In vehicles with manual temperature control, the
heating and air conditioning are operated using
three rotary switches. The air distribution flaps are
actuated via the air distribution flap/temperature
control flap actuating unit, which is connected via
a rod to the control assembly for the climate
control. The temperature control flap is also
actuated via the air distribution flap/temperature
control flap actuating unit, which is connected via
a cable to the control assembly. In addition, the
operating switch for recirculated air mode and the
on/off switch for the air conditioning are located on
the control assembly.
