Summary

A new configuration of a bi-ejector refrigeration system is presented. The system incorporates two ejectors. The purpose of one is to suck refrigerant vapour from the evaporator and discharge to the condenser; the other acts as a jet pump to pump liquid refrigerant from the condenser to the generator. An analysis model for the bi-ejector refrigeration system and a one-dimensional flow model for the gas-liquid ejector were established. The performances of the gas-liquid ejector and the refrigeration cycle were studied using numerical modelling. The results show that the performances of ejectors and system depend a great deal on the refrigerants as well as on operation conditions.
