PROCEDURE AND DEVICE OF THERMAL REGULATION OF A CAR VEHICLE HABITACLE.

摘要

Thermal regulation device for a motor vehicle, of the type comprising: - a heat pump (12) that includes a main circuit (14) of compressed refrigerant fluid that takes calories from a cold source (16) to transfer them at least partially to a hot source (18), - the cold source (16) including a first heat exchanger (24) cooling fluid / heat transfer fluid that thermally couples the main circuit (14) of cooling fluid to a first secondary circuit (26) of heat transfer liquid which can selectively be attached to at least two heat exchangers, - including the hot source (18) a second heat exchanger (34) cooling fluid / heat transfer fluid that thermally couples the main circuit (14) of cooling fluid to a second secondary circuit (36 ) of heat transfer liquid that can be selectively attached to at least two heat exchangers, characterized in that the first cir Secondary cup (26) can be selectively attached to a heat exchanger called outside (30) and to a heat exchanger called cold (32), because the second secondary circuit (36) can selectively join to the outside exchanger (30) and to a heat exchanger called hot (39), and because the device also includes an air conditioning group (62) comprising means (72) for joining a recycled air inlet of the passenger compartment (66), called recycled air inlet (66), in front of the exchanger cold (32)
