Abstract: A combined refrigerant heating and cooling system comprises a compressor, an outside heat exchanger, an inside heat exchanger, a refrigerant-to-engine coolant heat exchanger, at least one refrigerant expansion device and at least one redirection device, wherein the arrangement is such that said compressor is switchable between a heat pump loop and a cooling loop by means of said redirection device, said heat pump loop comprising said inside heat exchanger, said refrigerant expansion device and said refrigerant-to-engine coolant heat exchanger, and said cooling loop comprising said outside heat exchanger and said inside heat exchanger. According to the invention, the outside heat exchanger is arranged in such a way that an outlet of said outside heat exchanger is connected to a connection point of said heat pump loop which in heat pump mode lies downstream of said refrigerant expansion device, e.g. between said refrigerant expansion device and said refrigerant-to-engine coolant heat exchanger.
