The invention provides a heat storage and defrosting heat pump system of an electric automobile, a first medium A pumped out by a compressor sequentially passes through a condenser, an expansion valve and an evaporator and flows back to the compressor, two ends of the condenser are connected with a first medium A bypass branch in parallel, the first medium A bypass branch penetrates through a heat accumulator, a second medium B bypass branch penetrates through the heat accumulator, and the first medium A bypass branch and the second medium B bypass branch are connected in parallel. And a second medium B which flows through the second medium B bypass branch and exchanges heat with the motor system flows through the defrosting heat exchanger, and the defrosting heat exchanger and the evaporator are arranged close to each other. The system can ensure normal defrosting operation when power electrical equipment such as a motor, a battery and an inverter does not work or cannot provide effective heat energy at the initial working stage.
本发明提供一种电动汽车蓄热除霜热泵系统,压缩机泵出的第一介质A依次经由冷凝器、膨胀阀、蒸发器回流至压缩机,冷凝器两端并联有第一介质A旁通支路,第一介质A旁通支路穿置通过蓄热器,第二介质B旁通支路穿置通过蓄热器,流经第二介质B旁通支路的与电机系统实施换热的第二介质B流经除霜换热器,除霜换热器与蒸发器临近布置。本系统在电机、电池及逆变器等动力电器设备尚未工作或工作初期无法提供有效热能时能够保证正常除霜作业。
