THEORETICAL-ANALYSIS AND OPTIMIZATION OF A DOUBLE-EFFECT SERIES-FLOW-TYPE ABSORPTION CHILLER

A thermodynamic analysis was carried out to study the effect of design parameters, including heat recovery ratio and solution circulation ra tio, on the performance of a double-effect absorption chiller of the s eries-flow-type using water-lithium bromide as the working fluid. Incr eases in the heat recovery ratios of the high-temperature heat exchang er and the low-temperature heat exchanger and/or decreases in the solu tion circulation ratio improved the coefficient of performance. An inc rease in the heat recovery ratio of the high-temperature heat exchange r increased the total heat transfer area of the absorption chiller. Th e optimum design and operating conditions of a double-effect absorptio n chiller are suggested based on this cycle simulation analysis. Copyr ight (C) 1996 Elsevier Science Ltd.
