Abstract:In order to make the ejector refrigeration system reach subzero refrigeration, the ejector structure is optimized in this paper. A two-stage ejector model in series with two ejectors is proposed. Comparing with traditional single ejector models, the twostage ejector carries out a two boost of the secondary flow by connecting two ejectors in series. Using a water cooled condenser can also reduce the outlet pressure. Thus the pressure burden of a single ejector is reduced. The effectiveness of the proposed model is validated by simulation data.
