Theoretical analysis and optimization of a double-effect series-flow-type absorption chiller

摘要

A thermodynamic analysis was carried out to study the effect of design parameters, including heat recovery ratio and solution circulation ratio, on the performance of a double-effect absorption chiller of the series-flow-type using water-lithium bromide as the working fluid. Increases in the heat recovery ratios of the high-temperature heat exchanger and the low-temperature heat exchanger and/or decreases in the solution circulation ratio improved the coefficient of performance. An increase in the heat recovery ratio of the high-temperature heat exchanger increased the total heat transfer area of the absorption chiller. The optimum design and operating conditions of a double-effect absorption chiller are suggested based on this cycle simulation analysis.
