The invention relates to an electric parking heat pump air conditioning system suitable for severe cold regions. The system comprises a compressor, a four-way reversing valve, an outdoor heat exchanger, an outdoor fan, a first electronic expansion valve, an indoor fan, an indoor heat exchanger, a hot water-refrigerant heat exchanger, a second electronic expansion valve, a heat storage device and awater pump; the heat storage device stores heat from engine compartment hot water, releases heat when no engine waste heat water exists during parking rest, and indirectly provides hot water to forma double-heat-source refrigeration cycle on the whole. Compared with the prior art, the air conditioning system has the advantages that various problems of a traditional vehicle-mounted air conditioning system in the driving process can be well solved, an engine can be additionally cooled, and great help is provided for the whole vehicle-mounted operation work; more importantly, the energy storagedevice is additionally arranged, the heating capacity requirement can still be met when no engine waste heat water exists during parking in winter, and important significance is achieved for guaranteeing the riding comfort of workers during parking and resting.

    本发明涉及一种中适用于严寒地区的电动驻车热泵空调系统,包括压缩机、四通换向阀、室外换热器、室外风机、第一电子膨胀阀、室内风机、室内换热器,还包括热水‑制冷剂换热器、第二电子膨胀阀、蓄热装置、水泵,蓄热装置储蓄来自发动机舱热水的热量,在驻车休息无发动机余热水时释放热量,间接提供热水,整体上构成双热源制冷循环。与现有技术相比,本发明不仅能够很好的解决传统车载空调系统在行车时存在的种种问题,还能额外的给发动机降温,对于整个车载运行工作也有极大帮助;更重要的是增加了蓄能装置,在冬季驻车无发动机余热水时,仍能保证制热量需求,对于保障工作人员驻车休息时乘车舒适度具有十分重要意义。
