Title: METHOD FOR MANAGING A REVERSIBLE AIR-CONDITIONING CIRCUIT OF A MOTOR VEHICLE
Abstract:
The present invention concerns a method for managing a reversible air-conditioning circuit (1) capable of operating in: ◦ a cooling mode in which an interior air flow (100) intended for the passenger compartment is cooled, the heat energy recovered from the interior air flow (100) being discharged into an external air flow (200) outside the motor vehicle, ◦ a first dehumidifying mode in which the interior air flow (100) is cooled and then heated before arriving in the passenger compartment, ◦ a heat pump mode in which the interior air flow (100) is heated, the heat energy heating the interior air flow (100) being recovered from the external air flow (200), and ◦ a second dehumidifying mode in which the interior air flow (100) is cooled and then heated before arriving in the passenger compartment, the reversible air-conditioning circuit (1) comprising a central control unit (40) suitable for controlling the shifting from one operating mode to another according to a mode transition model which passes: ◦ in a first direction, through the cooling mode, the first dehumidifying mode, the second dehumidifying mode, then the heat pump mode, and ◦ in a second direction, through the heat pump mode, the second dehumidifying mode, the first dehumidifying mode, then the cooling mode.
