The invention discloses an electric automobile fresh air waste heat recovery heat management system and a control method, and belongs to the technical field of waste heat recovery. The system does not change an original system loop structure of an automobile, exhaust air of a passenger compartment is conveyed into the condenser, and the exhaust air is mixed with external inlet air; or the system adds a gas heat exchanger component in the HVAC assembly, and the gas heat exchanger component exchanges heat between the exhaust air of the passenger compartment and the inlet air of the air blower through an internal heat exchange filter element; or a small evaporator is additionally arranged in the loop of the original heat pump air-conditioning system of the automobile, and the evaporator is positioned between the compressor and the condenser; an air source of the evaporator comes from exhaust air of a passenger compartment. According to the method, more optimized configuration optimization design is adopted on the basis of the original vehicle configuration and characteristics, the energy-saving potential of the system can be effectively exerted, and the problem that the driving range of the vehicle is attenuated is solved.

    本发明公开了一种电动汽车新风余热回收热管理系统及控制方法,属于余热回收技术领域。系统不改变汽车的原有系统回路结构,将乘员舱排风输送到冷凝器中,将排风与外界进风进行混合;或者系统在HVAC总成中添加一个气体热交换器部件,气体热交换器部件通过内部热交换滤芯将乘员舱排风与鼓风机进风进行热交换;或者系统在汽车原有热泵空调系统的回路中添加一个小型蒸发器,蒸发器位于压缩机和冷凝器中间;蒸发器的风源来自于乘员舱排风。本发明基于原车构型和特性采用更为优化构型优化设计,可以有效发挥系统节能潜力,以改善汽车续驶里程衰减的问题。
