Abstract: A dual-stage enthalpy-increasing air-conditioning system comprises a compressor (1), an outdoor heat exchanger (3), a first throttle component (8) and an indoor heat exchanger (11), wherein the components are connected via pipelines; the system also comprises a flash evaporator (6) and a second throttle component (7); a first connecting port of the flash evaporator (6) is connected with a first connecting port of the first throttle component (8); a second connecting port of the first throttle component (8) is connected with the indoor heat exchanger (11); a second connecting port of the flash evaporator (6) is connected with an air supplementing port of the compressor (1); a third connecting port of the flash evaporator (6) is connected with a first connecting port of the second throttle component (7); a second connecting port of the second throttle component (7) is connected with the outdoor heat exchanger (3). The dual-stage enthalpy-increasing air-conditioning system could adjust evaporation capacity and air compensation at the same time, thereby enhancing the operation stability of the system.
