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:
z Compressor
The compressor draws in the R134a refrigerant and compresses it. This
raises the pressure and therefore the temperature of the refrigerant.
z 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.
z 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.
z Capillary tube
The capillary tube reduces the refrigerant from condensor pressure to
lower vaporisation pressure.
