The invention relates to the technical field of whole vehicle heat management, in particular to a pure electric vehicle whole vehicle heat pump integrated direct cooling and direct heating system and a control method, a positive temperature coefficient thermistor heater is omitted, part cooperation is optimized to efficiently absorb heat, a cooler is removed during refrigeration, heat exchange is improved, electric energy consumption is reduced, and the endurance is improved by 20%. Cost is effectively controlled, installation and maintenance processes are simplified, corresponding cost is reduced by 40%, and economical efficiency is improved. The system reliability is improved, two fault sources of a positive temperature coefficient thermistor heater and a cooler are reduced, the maintenance work is simplified, the difficulty and time are reduced, and the vehicle use efficiency is improved. The space in the vehicle is optimized, the weight is reduced, the space occupied by parts is released, layout flexibility is provided, loads are reduced, energy consumption is reduced, control is facilitated, the service life of the parts is prolonged, and therefore the problem that an existing whole vehicle heat pump integrated direct cooling and direct heating system is high in energy consumption is solved.

    本发明涉及整车热管理技术领域,具体涉及一种纯电汽车整车热泵集成直冷直热系统及控制方法,本发明取消正温度系数热敏电阻加热器并优化部件协同以高效吸热,制冷时去除冷却器并改进热交换,减少电能消耗提升20%续航。有效控制成本,简化安装维护流程减少相应成本40%,提高经济性。提升系统可靠性,减少正温度系数热敏电阻加热器和冷却器这两个故障源,简化维护工作,降低难度与时间,提升车辆使用效率。优化车内空间与减轻重量,释放部件所占空间提供布局灵活性,减轻负载降低能耗,利于操控与部件寿命,从而解决现有的整车热泵集成直冷直热系统能耗较高的问题。
