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
