摘要：【中文】本发明提供一种车辆的热泵空调系统及其控制方法，所述热泵空调系统包括由压缩机、四通阀、室外换热器、室内换热器等通过管路形成的空调制热、制冷回路；本发明的空调系统还包括蓄热器，通过所述蓄热器吸收动力电池、和/或室内电机，和/或室外电机产生的热量；所述蓄热器将其吸收的热量用于对室外风机除冰或除霜；和/或用于对室外换热器进行除冰或除霜。本发明通过回收室内电机、室外电机和动力电池产生的热量，使其热量融化室外侧风机的风叶和导流圈之间的冰雪，避免风叶卡死以及人工除冰雪工序。同时可利用电机和动力电池产生的热量，对室外侧换热器进行除霜，避免常规除霜过程中出现的车内降温以及人体不舒适。降低动力电池和电机的表面温度，提高其运行寿命。 【EN】The invention provides a heat pump air-conditioning system of a vehicle and a control method thereof, wherein the heat pump air-conditioning system comprises an air-conditioning heating and refrigerating loop formed by a compressor, a four-way valve, an outdoor heat exchanger, an indoor heat exchanger and the like through pipelines; the air conditioning system also comprises a heat accumulator, wherein the heat accumulator absorbs heat generated by the power battery and/or the indoor motor and/or the outdoor motor; the heat accumulator uses the heat absorbed by the heat accumulator to deice or defrost an outdoor fan; and/or for deicing or defrosting an outdoor heat exchanger. The invention recycles the heat generated by the indoor motor, the outdoor motor and the power battery, so that the heat melts the ice and snow between the fan blades and the flow guide ring of the outdoor fan, and the fan blades are prevented from being blocked and the manual ice and snow removing process is avoided. Meanwhile, the heat generated by the motor and the power battery can be utilized to defrost the outdoor heat exchanger, so that the temperature reduction in the vehicle and the discomfort of human bodies in the conventional defrosting process are avoided. The surface temperature of the power battery and the motor is reduced, and the service life of the power battery and the motor is prolonged.

摘要：【中文】本发明提供一种车辆热泵空调系统及其控制方法。本发明通过第一(板式)换热器和对压缩机进行补气(补气增焓压缩机)将制冷剂分成两路，补气回路制冷剂为压综机进行补气，主流路继续换热运行。并通过补气回路制冷剂来冷却主流路中的制冷剂，提高输气量，降低压缩机的排气温度。本发明的热泵空调系统还通过构建旁通支路的方式，使本发明的空调系统可在逆循环除霜控制和旁通除霜控制之间切换，可根据结霜量的不同，采用不同除霜控制，从而提高除霜效率。 【EN】The invention provides a vehicle heat pump air conditioning system and a control method thereof. The invention divides the refrigerant into two paths by the first (plate) heat exchanger and the compressor for air supplement (air supplement and enthalpy increase compressor), the air supplement loop refrigerant is used for air supplement for the pressure heald machine, and the main flow path continues heat exchange operation. And the refrigerant in the main flow path is cooled by the air supplementing loop refrigerant, so that the air delivery quantity is improved, and the exhaust temperature of the compressor is reduced. The heat pump air-conditioning system can switch between reverse circulation defrosting control and bypass defrosting control by constructing the bypass branch, and can adopt different defrosting controls according to different frosting amounts, thereby improving the defrosting efficiency.
