Thermal conditioning system

A thermal conditioning system for a motor vehicle, comprising:

• a heat-transfer fluid circuit for dielectric heat-transfer fluid, comprising:
• a primary heat-transfer fluid circulation loop,
• a secondary heat-transfer fluid circulation loop,
• a refrigerant circuit comprising a main refrigerant circulation loop, the main refrigerant circulation loop comprising in succession, in a direction of circulation of refrigerant:
• a compression device,
• a first heat exchanger, arranged both on the main refrigerant circulation loop and on the primary heat-transfer fluid loop, so as to allow a heat exchange between the refrigerant and the heat-transfer fluid,
• an expansion device,
• a second heat exchanger, arranged both on the main refrigerant circulation loop and on the secondary heat-transfer fluid loop, so as to allow a heat exchange between the refrigerant and the heat-transfer fluid,
• wherein:
• the primary heat-transfer fluid circulation loop comprises a third heat exchanger configured to exchange heat with an air stream inside a passenger compartment of the vehicle, and
• the secondary heat-transfer fluid circulation loop comprises a fourth heat exchanger configured to be thermally coupled to a first element of an electric drive train of the vehicle,
• wherein the heat-transfer fluid circuit comprises:
• a first bypass branch connecting a first connection point, positioned on the primary heat-transfer fluid circulation loop between a first outlet of the first heat exchanger and a first inlet of the third heat exchanger, to a second connection point, positioned on the secondary heat-transfer fluid circulation loop between a first outlet of the second heat exchanger and a first inlet of the fourth heat exchanger,
• a second bypass branch connecting a third connection point, positioned on the primary heat-transfer fluid circulation loop between a second inlet of the first heat exchanger and a second outlet of the third heat exchanger, to a fourth connection point, positioned on the secondary heat-transfer fluid circulation loop between a second inlet of the second heat exchanger and a second outlet of the fourth heat exchanger,
• and wherein:
• the heat-transfer fluid circuit comprises a third bypass branch connecting a fifth connection point, positioned on the secondary heat-transfer fluid circulation loop between the second outlet of the fourth heat exchanger and the fourth connection point, to a sixth connection point, positioned on the secondary heat-transfer fluid circulation loop between the first outlet of the second heat exchanger and the first inlet of the fourth heat exchanger, the third bypass branch comprising a fifth heat exchanger configured to exchange heat with the air stream inside the passenger compartment of the vehicle.
