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 be-
comes 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.
B1600PLUS und B2200:
Heating system(5)
The heating system warms the air and a blower distributes the air through
an air outlet unit.
B2600:
Heating system (5)
The refrigerant gas cycle can be inverted by a solenoid valve. The heat
accumulated by the refrigerant gas is dispersed by the internal heat ex-
changer and a blower distributes the air through an air outlet unit.
