Title
(EN) THERMAL CONDITIONING SYSTEM FOR A MOTOR VEHICLE
(FR) SYSTEME DE CONDITIONNEMENT THERMIQUE POUR VEHICULE AUTOMOBILE
Abstract
(EN)
The invention relates to a thermal conditioning system (100) for a motor vehicle, comprising: - a coolant circuit (1) comprising: - a main loop (A) successively comprising, in the direction of flow of the coolant: - a compression device (2); - a dual-fluid heat exchanger (3); - a first expansion device (4); - a first heat exchanger (5); - a first bypass branch (B) having a second heat exchanger (7) configured to exchange heat with an external air flow (Fe) outside the passenger compartment of the vehicle; - a second bypass branch (C) connecting a third connection point (13), which is located between an outlet of the compression device (2) and the first expansion device (4) along the main loop (A), to a fourth connection point (14), which is located between the first heat exchanger (5) and the second connection point (12) along the main loop (A), the second bypass branch (C) having a third expansion device (8) and a third heat exchanger (9); - a heat transfer fluid circuit (20), the dual-fluid heat exchanger (3) being arranged both along the coolant circuit (1) and along the heat transfer fluid circuit (20) so as to allow for heat exchange between the coolant and the heat transfer fluid, the main loop (A) comprising a first internal heat exchanger (21) configured to allow for heat exchange between the high-pressure coolant flowing downstream of the dual-fluid heat exchanger (3) and the coolant downstream of the second connection point (12).
