ABSTRACT:
An air conditioning unit comprises a cooling unit and a heating unit and is provided with dehumidifying mode for drying the through-flowing air. The operation of the dehumidifier results in activation of the cooling unit compressor, which reduces the air temperature inside the vehicle. Switching circuits are provided for compensating for this reduction in temperature. The compensation in the switching circuits is dependent on the outside temperature and is ineffective if the cooling unit is running at "full cooling" when the dehumidifier is switched on, or if the outside temperature is below 0 degrees centigrade.
