The invention relates to a method for regulating a compressor in a refrigerant circuit. The method comprises the following steps: S1, determining a thermal target state; s2, determining a target heat flow dQSoll or a variable proportional to the target heat flow at least partially according to the heat target state; s3, the actual heat flow dQIst or a variable proportional to the actual heat flow is determined, and the heat flow deviation Q between the actual heat flow dQIst and the target heat flow dQSoll or between the variable proportional to the actual heat flow dQIst and the variable proportional to the target heat flow dQSoll is determined; s4, regulating the compressor by means of a cascade regulation, an inner regulating circuit (R1) of the cascade regulation at least partially regulating the power, in particular the rotational speed, of the compressor as a function of the heat flow deviation Q determined in step S3, and an outer regulating circuit (R2) at least partially regulating the target heat flow dQSoll as a function of the heat target state determined in step S1.
