The invention relates to an extended-range automobile heat pump system which comprises an out-cabin heat exchanger, an in-cabin heat exchanger, a heat exchange core body, a plate heat exchanger, a cooler, a compressor, a liquid storage device, a four-way valve, a throttle pipe, an electronic expansion valve and an engine warm air core body. Through cooperation of engine water circulation and a heat pump air conditioning system, a heat management system is optimized, and energy distribution is optimized. The refrigerant circulation loop is adjusted through the four-way valve, in the refrigeration mode, the enthalpy value of refrigerant at an inlet of the compressor can be increased through introduction of the plate heat exchanger, and the refrigeration effect is enhanced. In the heating mode, the plate type heat exchanger absorbs exhaust refrigerant waste heat and is used for cab cold vehicle heating and out-of-cabin heat exchanger defrosting, the in-cabin heat exchanger is used for cab heating, water heating heating is switched after the water temperature of an engine rises, the problem of heating thermal inertia of a current hybrid vehicle type is solved, meanwhile, energy consumption of heat pump heating is greatly reduced, and the endurance mileage is increased.
本发明涉及一种增程式汽车热泵系统,包括舱外换热器、舱内换热器、换热芯体、板式换热器、冷却器、压缩机、储液器、四通阀、节流管、电子膨胀阀及发动机暖风芯体,该系统能够实现制冷模式和制热模式两种工况,利用发动机水循环和热泵空调系统的配合,优化热管理系统,优化能量分配。通过四通阀调节冷媒循环回路,在制冷模式下,板式换热器的引入可以增加压缩机进口冷媒的焓值,增强制冷效果。在制热模式下,板式换热器吸收排气冷媒余热,用于驾仓冷车采暖和舱外换热器化霜,舱内换热器用于驾仓制热,待发动机水温上升后切换为水暖制热,解决当期混动车型采暖热惯性问题同时大幅降低热泵制热的能耗,提升续航里程。
