A NOVEL ABSORPTION-RECOMPRESSION REFRIGERATION CYCLE

This paper reports on a novel ejector boosted single-effect absorption -recompression refrigeration cycle. In this cycle, a steam generator, ejector and a concentrator replace the high and low pressure generator s (concentrators) used in conventional double-effect absorption cycle machines, to reconcentrate the absorbent solution. The ejector here ac ts like a heat-pump to enhance the concentration process by increasing the flow of leaving vapour and by increasing the quantity of heat inp ut at the concentrator. The gaper provides a qualitative and quantitat ive description of the novel cycle and discusses design choices that l ead to optimum matching of the absorbent concentrator and ejector. The important role the ejector plays in this novel refrigeration cycle is discussed and some experimental data are presented. An experimental l ithium bromide refrigerator based on this cycle is described. (C) 1998 Elsevier Science Ltd. All rights reserved.
