12. A system for the thermal treatment of a vehicle comprising:
the refrigerant circuit for refrigerant comprising:
at least a main pipe,
a first leg, a second leg, and a third leg, all three legs in series with the main pipe,
the main pipe comprising at least a compression device for compressing the refrigerant and a main heat exchanger arranged in such a way as to have an external air flow external to an interior of the vehicle passing through it,
the first leg comprising at least a first heat exchanger thermally coupled to a loop for a heat-transfer liquid and an accumulator device for accumulating the refrigerant,
the second leg comprising at least a second heat exchanger thermally coupled to the loop for heat-transfer fluid, the third leg comprising at least a third heat exchanger configured to have passing through it an interior air flow sent into the vehicle interior,
wherein the first leg and the second leg are in parallel and meet at a point of convergence located between the accumulator device and the compression device, and
wherein the first leg and the third leg meet at a first junction point located between the first heat exchanger and the accumulator device; and
a loop for heat-transfer liquid thermally coupled to the refrigerant circuit for refrigerant fluid via the first heat exchanger and the second heat exchanger,
the first heat exchanger and the second heat exchanger being assigned to the thermal treatment of at least one same part of an electric traction driveline of the vehicle.
