A finite time analysis of combined Carnot driving and cooling cycles optimised for maximum refrigeration effect with applications to absorption refrigeration systems

Abstract

A finite time analysis of an ideal refrigeration cycle with the objective of maximising refrigeration effect has been performed. The optimised refrigeration cycle has then been combined with an optimised power cycle to produce a combined cycle. The general matching requirements of the two cycles are discussed. The cycles are then combined in a specific way such that they become a model for an ideal absorption refrigeration cycle. The influence of the design parameters on the performance of the combined cycle is analysed. The performance of an experimental absorption unit is compared with the predictions made by the analysis.
