The embodiment of the invention provides a compressor feedforward rotating speed calculation method and device based on a heat pump system, and relates to the technical field of heat management. The method includes calculating an air side refrigeration load of a passenger compartment using an air parameter; a refrigerant side load is obtained based on conversion of the air side refrigeration load; and calculating the actual rotating speed of the compressor based on the refrigerant side load. According to the method, the refrigerant side load is determined through the air side refrigeration load, the actual rotating speed of the compressor is calculated through the refrigerant side load, the calculation result is more accurate, calibration experiments are not needed, and the method is not limited by the displacement of the compressor and a used vehicle; the problems that an existing method needs a large number of calibration experiments and is limited by compressor displacement and using vehicles are solved.
