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 can achieve enthalpy increasing of the compressor through the economizer, the energy efficiency ratio of the compressor is effectively improved, meanwhile, the enthalpy-increasing air conditioning system is further provided with the third heat exchanger, heat exchange of a secondary refrigerant and a refrigerant is achieved through the third heat exchanger, and the energy efficiency ratio of the compressor is effectively increased. And the refrigerant returns to the compressor after absorbing the heat of the secondary refrigerant, so that the temperature of the refrigerant at the inlet of the compressor is increased, the compression amount of the compressor is reduced, the energy efficiency ratio of the compressor is further increased, the energy consumption is reduced, and the heating effect of the compressor is improved. And moreover, the electric drive system can be cooled through the third heat exchanger, so that the heat pump system and the secondary refrigerant system are organically combined together, the overall size and weight of the enthalpy-increasing air conditioning system are reduced, and the cruising ability of the electric automobile is prolonged.

    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,增焓空调系统通过经济器能够实现压缩机的增焓,使压缩机的能效比有效提升,同时,其还设置了第三换热器,通过第三换热器实现载冷剂和制冷剂的换热,使制冷剂吸收载冷剂的热量后回到压缩机,提高了压缩机入口处的制冷剂温度,降低了压缩机的压缩量,进一步提高了压缩机的能效比,降低了能源的消耗,提升了压缩机的制热效果。且,通过第三换热器还能够为电驱系统进行散热,使热泵系统和载冷剂系统有机地结合在了一起,减小了增焓空调系统的整机体积和重量,延长了电动汽车的续航能力。
