Abstract:
1. A motor vehicle temperature regulation apparatus, comprising: a heat pump comprising a main compression circuit for a refrigerant fluid taking heat from a cold source to transfer it to a hot source; the cold source comprising a first heat exchanger for exchanging heat between the refrigerant fluid and a coolant liquid, thermally coupling the main refrigerant circuit to a first secondary coolant circuit, capable of being selectively connected to an outside heat exchanger and to a cold heat exchanger; the hot source comprising a second heat exchanger for exchanging heat between the refrigerant fluid and a coolant liquid, thermally coupling the main refrigerant circuit to a second secondary coolant circuit, capable of being selectively connected to the outside heat exchanger and to a hot heat exchanger; and a subsidiary heat exchanger in heat exchange with a part of the vehicle that is to be temperature-regulated, the subsidiary heat exchanger being connected in parallel with the cold and hot heat exchangers.
