The invention provides a heat storage device and heat pump air conditioner coupled new energy automobile heat management system which comprises a heat pump air conditioner system, a passenger compartment heating loop and a heat storage device. The heat pump air conditioning system comprises a compressor, a second three-way valve, a second plate heat exchanger, a first electronic expansion valve, a defrosting heat exchanger, an outside-vehicle heat exchanger, a first three-way valve, a second electronic expansion valve, a refrigeration heat exchanger and a gas-liquid separator which are sequentially connected in series, and the other path of the first three-way valve is connected with a pipeline between the refrigeration heat exchanger and the gas-liquid separator. And the other path of the three-way valve II is connected with a pipeline between the electronic expansion valve I and the defrosting heat exchanger. On the basis of a traditional heat pump air conditioning system, the heat storage device is added to serve as an additional heat source, heat can be directly supplied to a passenger compartment, defrosting can be conducted on the heat pump system under the condition that the passenger compartment is kept in the heat supply state, waste heat generated by motor electric control and a power battery can be recycled, and heating and heat preservation can be conducted on the power battery. Therefore, the whole thermal management system can operate normally and efficiently.

    本发明提供一种储热装置与热泵空调耦合的新能源汽车热管理系统,包括热泵空调系统、乘客舱采暖回路以及储热装置,所述热泵空调系统包括依次串联的压缩机、三通阀二、板式换热器二、电子膨胀阀一、除霜换热器、车外换热器、三通阀一、电子膨胀阀二、制冷换热器以及气液分离器,所述三通阀一的另一路连接制冷换热器与气液分离器之间的管路,所述三通阀二的另一路连接电子膨胀阀一与除霜换热器之间的管路。在传统热泵空调系统的基础上,加入储热装置作为额外热源,既能够直接给乘员舱供热,又可以在保持乘员舱供热的状态下为热泵系统除霜,还可以回收电机电控与动力电池产生的废热并为动力电池加热保温,使得整个热管理系统得以正常、高效地运行。
