Abstract
The present invention relates to a method for controlling a thermal management device (1) of a motor vehicle comprising a refrigerant-fluid circuit comprising a compressor (3), a first heat exchanger (5), an expansion device (7) and the second heat exchanger (9), said thermal management device (1) further comprising an electric heating device (60), said control method involving, upon a starting of the thermal management device (1) from cold, the following steps: direct or indirect heating of the internal air flow (20) by the electrical heating device (60) alone until said internal air flow (200) reaches a target temperature and/or until a predetermined timer has run out, —when the internal air flow (200) has reached its target temperature and/or when the timer has run out, starting the compressor (3) so that the refrigerant-fluid circuit draws heat energy from the external air flow (100) at the second heat exchanger (9) and gives up said heat energy at the first heat exchanger (5).
