The utility model discloses a three-working-condition system with an ejector. The utility model discloses a single-stage compression refrigeration system for an air conditioner working condition. An ice-making working condition adopts a quasi-two-stage compression refrigerating system with an ejector and with air supplemented in the middle, and a winter heating working condition adopts a three-working-condition system of a quasi-two-stage compression heat pump system with an ejector and with air supplemented in the middle, so that the initial investment cost of the system is reduced, the energy consumption and the operating cost are reduced, and the energy is saved. The system comprises a compressor with a middle air supplementing function, a four-way reversing valve, an outdoor heat exchanger, an indoor heat exchanger, an ice making evaporator, an economizer, an ejector, a throttling device, an adjusting valve set and a plurality of valves. Through the switching of the valve and the regulating valve group, t
