Technical description
EC-2000-AC/DC
4.3 Operating principle
There are different ways of air conditioning the interior of vehicles using
the roof air conditioners.
The system can lower or raise the temperature within the vehicle to a
certain value. The cooling temperature depends on the type of vehicle,
the ambient temperature and the cooling capacity of your air conditioner.
For the cooling capacity of your air conditioner refer to the “Technical data”
section on page 63.
The refrigerant circuit of the roof air conditioner consists of four main
components:
ƒ Compressor
The compressor draws in the R407c refrigerant used and compresses
it. In this way, the pressure and hence also the temperature of the
refrigerant is raised.
ƒ Condenser
The built-in condenser works like a cooler or heat exchanger. The air
flowing by absorbs the heat and the hot refrigerant gas cools down and
condenses. The refrigerant becomes fluid.
ƒ Vaporiser
The vaporiser cools down the air flowing by and dehydrates it. The
refrigerant absorbs the heat. The cooled down air is distributed within
the vehicle by means of an air outlet unit.
At low temperatures, it is possible to heat up the outflowing air. To do this,
the drawn-in air is heated up by an electrical resistance heating. A thermostat
regulates the air temperature.
