Disclosed is a method for controlling a thermal conditioning system (100) that comprises: • - a refrigerant circuit (10) comprising: • -- a main loop (A) comprising: • - a compressor (7), • - a first heat exchanger (1) supplying a thermal power (Pw1) to a heat-transfer fluid (F1), • - a first expansion valve (31), • - a second exchanger (2), • -- a bypass branch (B) joining the second exchanger (2) and comprising a second expansion valve (32), the method comprising the steps of: • (i) receiving a thermal power setpoint (C_Pw) for the thermal power to be supplied to the heat transfer fluid (F1), • (ii) if the received setpoint (C_Pw) is lower than a predetermined threshold (P_Pw_min): • (iii) maintaining the rotational speed of the compressor (7) within a predetermined range (N1, N2), • (iv) determining a setpoint temperature (C_T_F1) for the heat-transfer fluid (F1), • (vi) controlling a flow area of the second expansion valve (32) so that the actual temperature (T_F1) of the heat-transfer fluid (F1) is equal to the setpoint temperature (C_T_F1), • (vii) controlling a flow area of the first expansion valve (31) so that the refrigerant at the inlet of the compressor (7) is in the superheated steam state.
