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 firstmode; 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.

    本发明涉及一种用于混合动力车辆或电动车辆的热调节回路(1),制冷剂能够在所述回路(1)中流通,所述回路(1)包括压缩机(3)、冷凝器(5)、蒸发器‑冷凝器(7)、蒸发器(9)和热联接到诸如车辆电池的电气构件的热交换器(11),其特征在于,所述回路被配置为至少以以下三种模式操作,在所述三种模式下,制冷剂能够串联地并相继地流通:‑在第一模式下,通过冷凝器(5)、蒸发器‑冷凝器(7)和蒸发器(9);‑在第二模式下,通过冷凝器(5)、蒸发器(9)和蒸发器‑冷凝器(7);以及在另一种模式,即第三模式下,其中蒸发器(9)与热交换器(11)和/或蒸发器‑冷凝器(7)并联布置,使得制冷剂能够串联地并且相继地流通通过冷凝器(5),然后通过并联布置的所述元件(7、9、11)中的至少两个。
