Technical description

The roof air conditioner can be used for variable air conditioning inside the
vehicle. The devices are operated by remote control.
Note
I
The air conditioner can lower or raise the temperature within the ve-
hicle to a certain value. The cooling temperature depends on the
type of vehicle, the ambient temperature and the cooling capacity
of your air conditioner. The cooling capacity of your air conditioner
see chapter "Technical data" on page 37.
The refrigerant circuit of the roof air conditioner consists of four main compo-
nents:
Compressor
The compressor draws in the R407c refrigerant and compresses it. This
raises the pressure and therefore the temperature of the refrigerant.
Condenser
The built-in liquifier works like a cooler or heat exchanger. The air flowing
past absorbs the heat and the hot refrigerant gas cools down and be-
comes liquid.
Vaporiser
The vaporiser cools down the air flowing past and dehydrates it. The re-
frigerant absorbs the heat and vaporises. The cooled air is distributed
within the vehicle through an air outlet unit.
Capillary tube
The capillary tube reduces the refrigerant from condensor pressure to
lower vaporisation pressure.
Note
I
At low temperatures, it is possible to heat up the outflowing air. To
do this, the drawn-in air is heated up by an electrical resistance
heating. A thermostat regulates the air temperature.
