The invention relates to the technical field of vehicle heat management, and discloses a vehicle heat management system and a control method and device thereof and a storage medium, the vehicle heat management system comprises a heat pump loop, and a first refrigeration branch and a second refrigeration branch which are connected with the heat pump loop in parallel, and the method comprises the steps that the current environment temperature of the environment where a vehicle is located is obtained, the current pressure of an outlet of the compressor; if the current environment temperature is lower than the preset temperature and the current pressure is lower than the preset pressure, the vehicle heat management system is controlled to work in a preset refrigerant pumping mode, so that a refrigerant in a first refrigeration branch and/or a second refrigeration branch is pumped into a heat pump loop; and after the refrigerant pumping mode is completed, the vehicle heat management system is controlled to work in a heat pump mode, so that a passenger compartment of the vehicle is warmed through a heat pump loop. Therefore, before the heat pump mode, the refrigerants in the other branches are extracted into the heat pump loop, the heat pump mode can be successfully started at a time, and the refrigerants cannot be lacked in the heat pump mode.

    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,及与热泵回路并联的第一制冷支路和第二制冷支路,方法包括:获取车辆所处环境的当前环境温度,以及压缩机出口的当前压力;若当前环境温度低于预设温度且当前压力低于预设压力,则控制车辆热管理系统以预设的抽冷媒模式工作,以将第一制冷支路和/或第二制冷支路中的冷媒抽取到热泵回路中;在抽冷媒模式完成后,控制车辆热管理系统以热泵模式工作,以通过热泵回路为车辆的乘员舱制暖。因此,在热泵模式之前,将其他支路中的冷媒抽取到热泵回路中,能够使得热泵模式一次性启动成功,且在热泵模式下不会缺少冷媒。
