Summary
In this paper, a new bi-ejector refrigeration cycle is presented, in which the mechanical pump of a single ejector refrigeration cycle is replaced by a vapour-liquid ejector. Thus in the bi-ejector refrigeration cycle, no electricity is required. The relation between the vapour-liquid ejector performance and operation parameters is studied. Simulation on the system COP, the generating temperature and the condensing temperature is provided. The vapour-liquid ejector entrainment ratio is relatively high, so the system performance remains competitive although a part of motive vapour is used to drive the vapour-liquid ejector, without counting the saving of electricity.
