The invention discloses a low-temperature efficient heating air conditioning system which comprises an outdoor evaporator, an indoor condenser, an economizer, a regulating valve and a mixing bin, the economizer is provided with a heating inlet, a heating outlet, a cooling inlet and a cooling outlet, and the outdoor evaporator is provided with an inlet, a first outlet and a second outlet. The cooling inlet is connected to an outlet of the indoor condenser, the cooling outlet is connected to the inlet, the heating inlet is connected to the first outlet, the heating outlet is connected to the mixing bin, the second outlet is connected to the mixing bin, and the adjusting valve is arranged between the second outlet and the mixing bin. Heat exchange is carried out through the economizer, waste heat is absorbed, waste heat recovery is achieved, the heating requirement is met, and the endurance mileage cannot be greatly reduced. Adjustment can be achieved through the opening degree of the adjusting valve, so that effective control is achieved, the compressor works under the stable working condition as much as possible, and the service life of the compressor is prolonged.

    本发明公开了一种低温高效制热的空调系统,其包括室外蒸发器、室内冷凝器、经济器、调节阀和混合仓,所述经济器设有加热进口、加热出口、冷却进口和冷却出口,所述室外蒸发器设有进入口、第一出口和第二出口,所述冷却进口连接于所述室内冷凝器的出口,所述冷却出口连接于所述进入口,所述加热进口连接于所述第一出口,所述加热出口连接于所述混合仓,所述第二出口连接于所述混合仓,所述调节阀设置于所述第二出口与所述混合仓之间。通过经济器进行热交换,吸收余热实现余热回收,既满足制热需求又可以续航里程不至于大幅减少。通过调节阀的开度能够实现调节,从而实现有效控制,使压缩机尽可能地在稳定的工况下工作,延长压缩机的使用寿命。
