Components

The refrigerant circuit of the under-bench 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 becomes 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 or heated air within the vehicle through an air
outlet unit.
• 4-way valve (5)
The 4-way valve reverses the cooling circuit. Thus the internal register of the
evaporator becomes a condenser and heats the air passing through.
• Electric heating element (6)
The electric heating element increases the heating effect when the outer
temperature is low.
• Air inlet (7), air outlet (8) for external heat exchanger
Air is sucked into the device through the air inlet and escapes through the air
outlet.
• Air inlet (9), air outlet (10) for internal heat exchanger
Air is sucked into the device through the air inlet and escapes through the air
outlet. The internal heat exchanger treats the air in order to be cold or hot
depending on active mode.
