A theoretical study of an innovative ejector powered absorption-recompression cycle refrigerator

This paper describes a novel cycle which uses a steam ejector to enhance th e concentration process by compressing the vapour from the lithium bromide solution to a state that it can be used to re-heat the solution from which it came. The energy efficiency and the performance characteristics of the n ovel cycle are theoretically investigated in this paper. The theoretical re sults show that the coefficient of performance (COP) of the novel cycle is better than the conventional single-effect absorption cycle. The characteri stics of the cycle performance show its promise in using high temperature h eat source at low cost. (C) 2000 Elsevier Science Ltd and IIR. All rights r eserved.
