A method for managing a thermal management device for a motor vehicle is disclosed. The device has a refrigerant circuit that circulates a refrigerant fluid. The circuit includes a main loop having, in the direction of circulation of the fluid, a compressor, a condenser configured to exchange heat energy with a first element, a first expansion device and a first evaporator configured to exchange heat energy with a second element. The device operates in a mode of strict cooling of the third element in which the condenser transfers heat energy to the first element and only the second evaporator absorbs heat energy from the third element. The method includes managing the open diameter of the first expansion device as a function of the ambient temperature so that the refrigerant fluid circulates inside the first evaporator, the open diameter of the first expansion device decreasing as the ambient temperature of the first element increases.
