4.2. CC 355 System Components Explanation 10 – 17
No. Description No. Description
10
Condenser Fan: The condenser fans, as well
as the compressor, will only be on when the air
conditioner operates in ‘cooling mode’. The
Conderser Fan helps to keep the condenser
cool and protects it from overheating.
14
Air Refreshment: This permits the entry of
outside air in order to increase the oxygen level
and to expel unwanted odors and impurities
from inside the vehicle.
11
Relay Plate: The relay plate receives the
orders from the controller and turns on the
condenser fans, evaporator blowers and the
compressor according to the selected operation
mode.
15
Compressor: When it is functioning, the
compressor draws the refrigerant from the
evaporator at its gassy state at low pressure,
compresses it by raising the pressure and
temperature and discharges it into the
condenser.
12
Temperature Sensor: Sensor to measure the
temperature and therefore providing important
data to the control system for an optimized air
conditioning performance.
16
Pressure Switch: The pressure switch is an
electrical device that monitors the working
pressures of the air-conditioner. Whenever
there is a change in the normal operational
pressure the compressor will shut down
immediately so to avoid breaking. Note: The
working pressure is monitored continuously
even when the air conditioner is off.
13
Evaporator Blower: The evaporator blowers
are on in both ventilation and cooling mode and
can operate at two speeds. The speed control
can be automatic or manual. The blowers blow
the cold air into the passenger compartment.
17
Clutch: The compressor is powered by the
vehicle engine with a belt transmission power
system and a magnetic clutch whenever the air
conditioner is operating in ‘cooling mode’.
