30 ABSTRACT The present invention relates to a method for managing an indirect reversible air-conditioning circuit (1) for a motor vehicle, comprising a first refrigerant loop (A), wherein a refrigerant circulates and comprising a first dual-fluid heat exchanger (5) arranged together on the first refrigerant loop (A) and on a second heat-transfer fluid loop (B), wherein a first heat-transfer fluid circulates, said circuit being able to operate according to: • a heat pump mode, and • a heat pump dehumidification mode, derived from the heat pump mode, when the indirect air-conditioning circuit (1) is in heat pump mode or heat pump dehumidification mode, a central control unit (90) controls the device for redirecting the first heat-transfer fluid so that: • if the temperature measured at a temperature sensor (72) is greater than or equal to T72t + Y1, the first heat-transfer fluid is redirected both to an internal radiator (54) and to an external radiator (64), • if the temperature measured at the temperature sensor (72) is less than or equal to T72t - Y2, the first heat-transfer fluid is redirected only to the internal radiator (54).
