Parts of the refrigerant circuit

AC compressor
Note
The AC compressor contains refrigerant oil, which can be mixed
with the R 134a refrigerant at all temperatures.
The vehicles assembled in India:
The component of the AC compressor is the air conditioner mag‐
netic coupling - N25- , generates the shaft grip between the pulley
and compressor shaft.
Other vehicles:
The externally regulated AC compressor 6 SEU 12C with variable
stroke volume is driven by the engine using the V-ribbed belt. It
does not have a magnetic clutch.
The belt pulley/compressor shaft grip occurs via a driver clutch.
The displacement of the AC compressor is controlled via an ex‐
ternally driven regulating valve with PWM signal on the suction
side in accordance with the required cooling output.
The AC compressor continues operating with a minimum power
supply requirement even when the air conditioning system is off.
The AC compressor sucks refrigerant gas from the evaporator,
compresses it and transfers it to the condenser.
Condenser
As of MY 2011, a different shape than in the illustration
The condenser dissipates heat from the compressed refrigerant
gas into the ambient air.
During this process the refrigerant gas condenses and liquifies.
Fluid reservoir
The fluid reservoir -6- is a component part of the condenser.
It gathers the liquid drops and conveys them to the expansion
valve in a constant flow.
Humidity, that has penetrated into the refrigerant circuit during
assembly, is bound by a dessicator cartridge -5- integrated in the
fluid reservoir.
As of MY 2011, the dryer tank is attached to the left side of the
condenser.
