Abstract

The invention relates to a circuit (1) for the air-conditioning of a vehicle passenger compartment, including: a first portion (2) of the circuit (1), which extends between an inlet (5) of a first compression means (6) and an outlet (7) of a first expansion member (8), said first portion (2) including at least one outer exchanger (15) dividing said first portion (2) into a first sector (24) located upstream from said outer exchanger (15) and a second sector (24) located downstream from said outer exchanger (15); a third portion (4) of the circuit (1), which extends between an outlet (22) of a second expansion member (25) and an outlet (30) of a second compression means (31), said third portion (4) including an evaporator (32) dividing said third portion (4) between a first area (33) located upstream from the evaporator (32) and a second area (34) located downstream from said evaporator (32), characterized in that the circuit (1) includes a first means (35) which connects the first area (33) to the first sector (23) and a second means (36) which connects the second sector (24) to the second area (34).
