According to the enthalpy-increasing air conditioning system, the electric automobile and the control method of the enthalpy-increasing air conditioning system, the enthalpy-increasing air conditioning system is additionally provided with the first bypass pipeline, the second bypass pipeline and the control valve assembly, so that the enthalpy-increasing air conditioning system can still work in an indoor heating mode or an indoor refrigerating mode; refrigerants can enter from the same inlet of the economizer, so that the refrigerants flowing out of the economizer channel can achieve the enthalpy increasing function on the compressor under any condition; in addition, in the indoor heating mode, the refrigerant flowing out of the first channel of the economizer can be divided into three paths, the first path flows to the outdoor heat exchanger through a first throttling valve, the second path flows to the second channel of the economizer through a second throttling valve, and the third path flows to the battery heat dissipation heat exchanger through a third throttling valve. And the third path of refrigerant flows back to the compressor after absorbing the heat of the battery assembly in the battery heat dissipation heat exchanger, so that battery cooling can be started during indoor heating, the heat of the battery can be recycled, and the energy loss can be reduced.
本申请提供一种增焓空调系统、电动汽车及增焓空调系统的控制方法,增焓空调系统增设了第一旁通管路、第二旁通管路和控制阀组件,使得增焓空调系统无论是在室内制热模式下,还是在室内制冷模式下,制冷剂均能够由经济器的同一入口进入,从而使得流出该经济器通道的制冷剂在任何情况下均可实现对压缩机的增焓功能;另外,在室内制热模式下,从经济器的第一通道流出的制冷剂能够分为三路:第一路经第一节流阀流向室外换热器,第二路经第二节流阀流向经济器的第二通道,第三路经第三节流阀流向电池散热换热器,第三路制冷剂在电池散热换热器吸收电池组件热量后流回压缩机,从而使得在室内制热时也能开启电池冷却,回收电池热量,有助于减少能源损耗。
