The invention provides a heat pump system control method, device and equipment and a storage medium, and relates to the technical field of vehicles. The heat pump system control method comprises the steps that when a compressor is shut down, whether the compressor is shut down abnormally or not is judged; when the compressor is shut down abnormally, whether the compressor has a rotating speed request or not is judged; and when the compressor has the rotating speed request, the pressure equalizing valve is locked according to the preset opening degree. When the compressor is shut down abnormally and the rotating speed request exists, the pressure equalizing valve is locked according to the preset opening degree, for example, the opening degree of the pressure equalizing valve is locked to be 40%, it can be guaranteed that high pressure and low pressure are rapidly balanced, and the pressure difference rapidly falls back to the pressure difference starting range of the compressor single body; the liquid refrigerant on the high-pressure side cannot excessively migrate to the low-pressure side, and the problems of liquid impact and the like caused by excessive liquid carried by the low-pressure side when the compressor is started next time are solved.

    本发明提供了一种热泵系统控制方法、装置、设备及存储介质,涉及车辆技术领域。本发明所述的热泵系统控制方法,包括:当所述压缩机停机时,判断所述压缩机是否异常停机;当所述压缩机异常停机时,判断所述压缩机是否存在转速请求;当所述压缩机存在转速请求时,按照预设开度锁定所述均压阀。本发明通过在压缩机异常停机且存在转速请求时,按照预设开度锁定均压阀,例如将均压阀的开度锁定为40%,既能保证高低压快速均衡,使压差迅速回落至压缩机单体压差启动范围内,同时由于均压阀的开度不大,可以保证高压侧液态冷媒不会过多的往低压侧迁移,防止下次压缩机启动时由于低压侧带液过多导致出现液击等问题。
