Abstract

A heat pump system for a motor vehicle is disclosed. The heat pump system includes a refrigerant circuit that is flowable through by a refrigerant. The refrigerant circuit has a first partial circuit with a low pressure accumulator, a compressor, a heat pump heater, and an exterior heat exchanger. The refrigerant circuit has a second partial circuit with an evaporator and a chiller. The refrigerant circuit has a valve arrangement. The first partial circuit and the second partial circuit are fluidically connected with one another exclusively via the valve arrangement.
