摘要：A new bi-ejector refrigeration system to recover the low-grade waster heat widely available for industries was presented. The mechanical circulation pump was replaced with a liquid-vapor ejector. No electricity power was needed in this refrigeration cycle. The relationship between the liquid-vapor ejector operation characteristics, its performance and the operation parameters were investigated. It is shown that the system performance goes up with the increase of operation pressure in some scope, and then drops. The relationship between the coefficient of performance (OOP) and the generator temperature, the condenser temperature was analyzed. Efficiency simulation on this bi-ejector under different waster heat temperatures is presented. R123 is shown to be a promising working fluid and COP reaches 0.3.
