ABSTRACT:
An air conditioner in a motor vehicle containing a refrigerant circuit, which includes an evaporator, an output-controlled compressor that is driven by an engine, a condenser and an expansion device is provided. The evaporator and the condenser are each assigned a blower for applying an air flow. To operate the air conditioner, there is provided an electronic control device which, as a function of input signals, generates output signals for driving actuators for output-controllable components of the air conditioner. For this purpose, at least two state variables of the refrigerant circuit are detected, and the cutoff function of the compressor is determined from a comparison of (i) a value, derived from the at least two state variables and relating to the current delivery rate of the compressor, with (ii) a prescribed value for the maximum delivery rate.
