Abstract:
Motor vehicle temperature regulation apparatus comprising:a heat pump comprising a main compression circuit for a refrigerant fluid that takes heat from a cold source to transfer the heat 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 at least two heat exchangers; and 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 two heat exchangers; wherein the first secondary circuit is capable of being selectively connected to an â€œoutsideâ€  heat exchanger and to a â€œcoldâ€  heat exchanger, and wherein the second secondary circuit is capable of being selectively connected to the outside heat exchanger and to a â€œhotâ€  heat exchanger, the apparatus further comprising a unit that forms a flow of recycled cabin air passing through the cold heat exchanger.
