Abstract
A compressor control method and apparatus, a device and a storage medium. The control method comprises: acquiring a demand of an evaporator for refrigeration; on the basis of the demand for refrigeration, determining a first compressor rotating speed; acquiring evaporation temperature error data of the evaporator; on the basis of the evaporation temperature error data, determining a second compressor rotating speed; according to the first compressor rotating speed and the second compressor rotating speed, calculating a target compressor rotating speed; and, on the basis of the target compressor rotating speed, controlling a compressor. The control method enables rotating speeds of compressors to be closer to rotating speeds of actual refrigeration requirements and effectively reduces errors, allowing air conditioning systems to exert the optimal efficiency.
