The invention relates to the technical field of vehicle heat management, and discloses a vehicle heat pump mode control method, a heat management system, equipment and a storage medium. The vehicle heat management system comprises a heat pump loop and a refrigeration branch, and an outlet of the refrigeration branch communicates with an inlet of a compressor of the heat pump loop; the method comprises the following steps: detecting a current working mode of the thermal management system; wherein the working mode of the heat management system comprises a heat pump mode for heating a passenger compartment; and if the current working mode is the heat pump mode, the refrigeration branch is controlled to be conducted at the preset conduction degree, and the conduction duration is maintained to be the preset duration, so that the compressor can extract the refrigerant through the refrigeration branch to reach the standard pressure ratio. Therefore, in the heat pump mode, more refrigerants can be sucked into the compressor by controlling the refrigeration branch to be conducted at the preset conduction degree, so that the compressor can reach the standard pressure ratio to successfully start the heat pump function, the starting failure of the heat pump function is avoided, and the user experience is improved.
本申请涉及车辆热管理技术领域,公开了一种车辆热泵模式的控制方法、热管理系统、设备及存储介质,车辆热管理系统包括热泵回路以及制冷支路,制冷支路的出口与热泵回路的压缩机的进口连通,此方法包括:检测热管理系统的当前工作模式;其中,热管理系统的工作模式包括对乘员舱制热的热泵模式;若当前工作模式为热泵模式,则控制制冷支路以预设导通度导通并维持导通时长为预设时长,以使得压缩机能够通过制冷支路抽取冷媒而达到标准压比。因此,在热泵模式下,通过控制制冷支路以预设导通度导通,能够将更多的冷媒吸入到压缩机中,进而使得压缩机能够达到标准压比以成功地启动热泵功能,避免热泵功能启动失败,以提升用户体验。
