For capacities, see workshop manual for specific vehicle.
Electrical air conditioner compressor
WARNING
Danger of short circuit
The air conditioner compressor operates with 288 volts and at
a speed range of 800 to 8,600 rpm.
Do not touch air conditioner compressor when drive units are
starting. Danger of short circuit!
The air conditioner compressor draws refrigerant gas from the
evaporator, compresses it and sends it to the condenser.
Note
The air conditioner compressor contains refrigerant oil, which
♦
is miscible with R134a refrigerant at all temperatures.
The maker's nameplate states the refrigerant for which the air
♦
conditioner compressor is suitable. The flow rate is controlled
via the engine speed.
The engine should be started only when the refrigerant circuit
♦
has been fully assembled
The air conditioner compressor has an internal oil circuit to
♦
ensure that the air conditioner compressor is not damaged
when the refrigerant circuit is empty. This means that about
3
40 to 50 cm refrigerant oil remain in the air conditioner com‐
pressor.
♦ The air conditioner has a pressure relief valve.
2.1.6 Condenser
The condenser transfers heat from the compressed refrigerant
gas to the surrounding air.
This allows the refrigerant gas to condense into liquid form.
