The invention relates to the technical field of vehicle thermal management, and discloses a vehicle thermal management system, a control method and device of the vehicle thermal management system and a storage medium. The vehicle thermal management system comprises a heat pump loop and a hot gas bypass branch, and an inlet of the hot gas bypass branch communicates with an outlet of a compressor of the heat pump loop; the method comprises the steps that when a passenger compartment heating instruction is detected, the current environment temperature of the environment where the vehicle is located is obtained; and if the current environment temperature is within the first preset temperature range, the heat pump loop is controlled to work to heat the passenger compartment, and the hot gas bypass branch is controlled to extract the refrigerant at the outlet of the compressor. Therefore, when the heat pump mode is operated in the low-temperature environment, the refrigerant at the outlet of the compressor is guided into the front of the heat converter through the hot gas bypass branch, the superheat degree at the inlet of the compressor can be guaranteed, the compressor can normally operate in the low-temperature environment, and the heating effect of a passenger compartment is guaranteed.

    本申请涉及车辆热管理技术领域,公开了一种车辆热管理系统及其控制方法、设备及存储介质,车辆热管理系统包括热泵回路及热气旁通支路,热气旁通支路入口与热泵回路的压缩机出口连通,出口与热泵回路的热转换器与第一阀体之间的部分连通,方法包括:检测到乘员舱制热指令,则获取车辆所处环境的当前环境温度;若当前环境温度位于第一预设温度范围内,则控制热泵回路工作为乘员舱制热,并控制热气旁通支路抽取压缩机的出口处的冷媒。因此,在低温环境下运行热泵模式时,通过热气旁通支路将压缩机出口处的冷媒导入到热转换器前,能够保证压缩机入口处有过热度,使压缩机在低温环境下能正常运行,保证对于乘员舱的制热效果。
