The invention discloses a preheating control method and device for a compressor, a storage medium and an air conditioner. The method includes the steps that the outdoor environment temperature and thecompressor oil temperature are obtained when a unit which the compressor belongs to is electrified are obtained; whether the compressor needs to be preheated or not is determined according to the outdoor environment temperature and the compressor oil temperature; and if the compressor needs to be preheated, the compressor is preheated. By means of the scheme, the problem that when the compressorneeds to be preheated, unrecoverable damage will be caused to the unit when the unit is started immediately after being electrified can be solved, and the effect that the unit is not likely to be damaged is achieved.
