Beschreibung
Zusammenfassung:	An air conditioner for motor vehicles has a refrigerant circuit in which the refrigerant is brought into a wet vapor state. The refrigerant circuit is comprised among other things of at least one compressor (37) and a pressure ramming machine (14') which serves as an expansion device. By means of the pressure ramming machine (14'), energy is recovered during the expansion process which can be used in the circuit for compressing the refrigerant. In addition, a method for operating an air conditioner for motor vehicles is described, according to which a pressure ramming machine is integrated into the refrigerant circuit and refrigerant is brought into a wet vapor state in the pressure ramming machine (14').
