NOTE
The roof 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 roof air
conditioner.
Below an outer temperature of 16 °C the roof air conditioner doesn't
cool anymore.

Components

The refrigerant circuit of the roof air conditioner consists of the following main
components (fig. 1, page 3):
• Compressor (1)
The compressor draws in the refrigerant used and compresses it. This raises the
pressure and therefore the temperature of the refrigerant.
• Condenser (2)
The built-in liquefier works like a cooler or heat exchanger. The air flowing past
absorbs the heat and the hot refrigerant gas cools down and becomes liquid.
• Evaporator (3)
The evaporators cool down and dehumidify the air flowing past them. The
refrigerant absorbs the heat and vaporises.
• Blower (4)
A blower distributes the cooled air within the vehicle through an air outlet unit.
