| 摘要 |
<p>The invention relates to a method for controlling a thermal conditioning unit 1 of a vehicle passenger compartment, comprising an air-conditioning circuit 8 through which a refrigerant flows and a primary circuit 25 through which a first heat transfer fluid flows, the air-conditioning circuit 8 comprises at least one compressor 9, a first heat exchanger 10 designed to ensure heat exchange in order to influence the temperature of an interior air flow 3 sent into the passenger compartment and an exterior heat exchanger 13, the primary circuit 25 comprises at least one primary heat exchanger 28 designed to ensure heat exchange between the first heat transfer fluid and the interior air flow 3, said unit comprising a second heat exchanger 24 designed to ensure heat exchange between the refrigerant and the first heat transfer fluid and installed in the air-conditioning circuit 8 downstream of the first heat exchanger 10 in the direction of movement of the refrigerant in the air-conditioning circuit 8, characterized in that: a) a risk of icing of the external heat exchanger 13 is determined, b) if step a) is confirmed, the heat exchange in the first heat exchanger 10 is reduced or suppressed.</p> |
