Patent ID: 11912100

Abstract:
The invention relates to a thermal conditioning circuit (1) for a hybrid or electric motor vehicle, in which a refrigerant can circulate, said circuit (1) comprising a compressor (3), a condenser (5), an evaporator-condenser (7), an evaporator (9) and a heat exchanger (11) thermally coupled to an electric member, e.g. a vehicle electric battery, characterized in that the circuit is configured to operate at least in the following three modes in which the refrigerant can circulate in a cascade and successively:—via the condenser (5), the evaporator-condenser (7) and the evaporator (9) in a first mode;—via the condenser (5), the evaporator (9) and the evaporator-condenser (7) in a second mode; and—in another mode, i.e. a third mode, in which the evaporator (9) is arranged in parallel to the heat exchanger (11) and/or to the evaporator-condenser (7) such that the refrigerant can circulate in a cascade and successively via the condenser (5) and then via at least two of said elements (7, 9, 11) that are arranged in parallel.
