7.1 Components
The refrigerant circuit of the roof air conditioner consists of the following main
components (fig. 1, page 3):
z Compressor (1)
The compressor draws in the refrigerant used and compresses it. This
raises the pressure and therefore the temperature of the refrigerant.
z 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.
z Evaporator (3)
The evaporators cool down and dehumidify the air flowing past them. The
refrigerant absorbs the heat and vaporises.
z Blower (4)
A blower distributes the cooled air within the vehicle through an air outlet
unit.
