The invention discloses a direct type heat pump air conditioning system which comprises a refrigerant four-way valve, an outdoor heat exchanger, an indoor heat exchanger, an electric compressor and a gas-liquid separator, heat is absorbed from ambient temperature air, energy consumption of the air conditioning system is reduced, and the endurance mileage of a new energy automobile in winter is increased. The system is simple in structure, related parts are few, the refrigerant four-way valve and the electronic expansion valve are used as the core, the indoor heat exchanger plays a role of a condenser and an evaporator at the same time, so that an air conditioner host can be directly borrowed, the pipeline complexity is low, a special heat pump air conditioner controller is needed, and accurate control can be achieved.
本发明公开一种直接式热泵空调系统,使用直接式热泵空调系统,包括冷媒四通阀、室外换热器、室内换热器、电动压缩机和气液分离器,从环境温度空气中吸收热量,减少空调系统的能量消耗,提高新能源汽车的冬季续航里程。本系统架构简洁,涉及的零部件较少,核心是冷媒四通阀和电子膨胀阀,由于室内換热器同时起到冷凝器和蒸发器的作用,因此空调主机可直接借用,管路复杂程度较低,需专用热泵空调控制器,可实现精确控制。
