5 Technical description

The parking cooler can be used for variable air conditioning inside the vehicle. The

air in the interior is guided into the system through the intake grille, cooled, dried and

conveyed back into the interior through the blower nozzles. The system is operated

using the control panel or the remote control.

The system is fitted with a battery monitor. If the system is operated when the vehicle

ignition is switched off, the parking cooler switches off automatically as soon as the

supply voltage falls below a set level.

The refrigerant circuit of the parking cooler consists of four main components:

• Compressor

The compressor draws in the R-134a 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 the higher condenser pressure to

the lower vaporisation pressure.

• Vaporiser

The vaporiser cools down the air flowing past and dehumidifies it. The refrigerant

absorbs the heat and vaporises. The cooled air is distributed within the vehicle

through an air outlet unit.

NOTE

The parking cooler 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 parking cooler.

For the cooling capacity of your parking cooler, see chapter “Technical

data” on page 23.
