Technical description

The air conditioner can be used for variable air conditioning inside the vehi-
cle. The system is operated using the control panel or the remote control.
The air conditioner can lower the temperature within the vehicle to
a certain level. The temperature reached when cooling depends
on many factors, such as the size of the cab, the ambient temper-
ature, the heat and the cooling power of your air conditioner.
The circulating air is dehumidified while it is operating. A pleasant climate
is achieved even for slight temperature differences by dehumidifying.
Any condensation automatically flows out the evaporator unit.
The refrigerant circuit of the air conditioner consists of four main components:
Compressor
The compressor draws in the R134a refrigerant and compresses it. This
raises the pressure and therefore the temperature of the refrigerant.
Condenser
The built-in condenser works like a cooler or heat exchanger. The air
flowing past absorbs the heat and the hot refrigerant gas cools down and
becomes liquid.
Capillary tube
The capillary tube reduces the refrigerant from higher condenser pres-
sure to lower vaporisation pressure.
Vaporiser
The vaporiser cools down the air flowing past and dehydrates it. The
refrigerant absorbs the heat and vaporises. The cooled air is distributed
within the vehicle through an air outlet unit.
