Abstract
A vehicle air conditioner with a refrigerant circuit has as components at least one evaporator, a refrigerant compressor, a refrigerant condenser, an expansion valve associated with the evaporator and at least one heat exchanger with an associated expansion valve for coupling with a coolant circuit of a heat source, wherein the components are connected by a refrigerant line. A refrigerant container is provided which is connected on the high-pressure side of the refrigerant compressor with the refrigerant line and has a refrigerant-receiving chamber with a controllable volume, and a control unit is provided with which the volume of the chamber of the refrigerant container is controlled as a function of operating parameters of the refrigerant circuit. Alternatively, the refrigerant container is connected on the high-pressure side of the refrigerant compressor with the refrigerant line by way of a branch line.
