摘要： Method for controlling a refrigerant circuit (1) by for determining the supply voltage of a fan coupled with a condenser of a refrigerant circuit comprising an evaporator, a condenser and a compressor, the method comprising the following steps: measuring (100) the pressure P ev of the evaporator; measuring (110) the pressure P cond of the condenser; calculating (120) a pressure ratio P r between the pressure P cond of the condenser and pressure P ev of the evaporator; determining (140) the power demand of the compressor C pr-demand ; calculating (160) an optimized supply voltage V BEST-EER of the fan of the based on the calculated pressure ratio P r and based on the determined power demand C pr-demand ; and supplying to the fan a voltage corresponding to the optimized supply voltage V BEST-EER .
