The invention discloses a compressor frequency conversion control method, belongs to the technical field of compressors, solves the problems of high delay and large temperature deviation of compressor frequency conversion control, and comprises the following steps: A, determining an initial compressor rotating speed according to a preset reasonable coldest evaporation temperature; b, according to a feedback signal provided by the evaporation temperature, the rotating speed of a compressor is adjusted according to an automatically-controlled PID adjusting rule, and the final actual evaporation temperature is made to be equal to the reasonable coldest evaporation temperature; c, the adjusting signal of the rotating speed of the compressor is transmitted to an electric air conditioner compressor controller through the VCU in a CAN communication mode, and the rotating speed of the compressor is adjusted; and D, the user adjusts the opening degree of the temperature air door according to the requirements of the user, and the cold and hot degree of the air outlet temperature is adjusted. The method is used for frequency conversion optimization control of the automobile refrigeration compressor, and frequency conversion adjustment is controlled more timely and accurately.
