Abstract
The invention relates to a thermal conditioning circuit () for a hybrid or electric motor vehicle, in which a refrigerant can circulate, said circuit () comprising a compressor (), a condenser (), an evaporator-condenser (), an evaporator () and a heat exchanger () 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 (), the evaporator-condenser () and the evaporator () in a first mode;—via the condenser (), the evaporator () and the evaporator-condenser () in a second mode; and—in another mode, i.e. a third mode, in which the evaporator () is arranged in parallel to the heat exchanger () and/or to the evaporator-condenser () such that the refrigerant can circulate in a cascade and successively via the condenser () and then via at least two of said elements () that are arranged in parallel.
