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) comprising: a compression device (2), a dual-fluid heat exchanger (3), a first expansion device (4), a first heat exchanger (5) exchanging heat with an interior air flow (Fi) inside a passenger compartment of the vehicle, a second expansion device (6), a second heat exchanger (7) exchanging heat with an external air flow (Fe) outside the passenger compartment; - a first bypass branch (B) connecting a connection point located upstream of the second heat exchanger (7) to a connection point located downstream of the second heat exchanger (7); - a second bypass branch (C) connecting the main loop (A) to the first bypass branch (B); - a heat transfer fluid circuit (20), the dual-fluid heat exchanger (3) being provided to allow for heat exchange between the coolant and the heat transfer fluid, the coolant circuit (1) having a first internal heat exchanger (21), characterized in that the coolant circuit (1) also includes a third bypass branch (D-1, D-2, D-3) that allows the coolant flowing in the main loop (A) upstream of the first heat exchanger (5) to flow to the second heat exchanger (7) without penetrating the first heat exchanger (5).
