An air-conditioning system with a refrigerant medium circulating in a refrigerant
loop has a variable-stroke compressor with a high-pressure outlet chamber, a drive
chamber and an intake suction chamber. A first valve regulates a first flow of
refrigerant medium from the high-pressure outlet chamber to the drive chamber,
and a second valve regulates a second flow of refrigerant medium from the drive
chamber to the intake suction chamber. The first and second valves operate independently
of each other under the control of a control unit, and the variable stroke of the
compressor is controlled by the first and/or second flow of refrigerant medium.
