Abstract (en)

[origin: WO2019243727A1] The invention relates to a heat treatment system (1) for a vehicle, comprising at least one refrigerant fluid circuit (2), a liquid coolant loop (3) and a first heat exchanger (5) which thermally couples the liquid coolant loop (3) with the refrigerant fluid circuit (2), the liquid coolant loop (3) comprising at least one heat exchanger (12, 35) configured to dissipate calories in an airflow (18, 19), the refrigerant fluid circuit (2) comprising at least one compression device (4), the first heat exchanger (5), a refrigerant fluid accumulation device (6), a first expansion device (16) and a second heat exchanger (17) arranged to be traversed by an internal airflow (18) sent into the passenger compartment of the vehicle. The invention is characterized in that the refrigerant fluid circuit (2) comprises a branch (20) arranged in parallel with the first expansion device (16) and the second heat exchanger (17), said branch (20) comprising a second expansion device (21) and a third heat exchanger (22) capable of being thermally coupled to at least one component of an electric traction chain of the vehicle.
