6 Technical description
The roof air conditioner can be used for variable air conditioning inside the
vehicle. The devices are operated by a control panel.
I Note
The air conditioner can lower the temperature within the vehicle to
a certain level. The temperature depends on the type of vehicle, the
ambient temperature and the cooling capacity of your air condition-
er. The cooling capacity of your air conditioner see chapter "Tech-
nical data" on page 27.
The refrigerant circuit of the roof air conditioner consists of four main compo-
nents:
Compressor
The compressor draws in the R134a 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.
