The aim of this work is to carry out a thermoeconomic analysis of a single and double-effect LiBr/H2O absorption refrigeration system. The methodology of functional analysis with negentropy is used. The exergetic cost of the main product, the cooling cost, was calculated as a function of the exergy of the heat source. Two cases were analyzed for each system: the first considers a direct-fired s...

recently, many countries have paid substantial attention to power generation from biomass gasification, particularly through small-scale plants. a number of power plant models have been suggested and analyzed; however, certainly, desirable configurations have not been identified yet. moreover, their performances are ordinarily difficult to compare, especially owing to the fact that working hypo...

A simple vapor-compression refrigeration system becomes ineffective and inefficient as it consumes a huge energy supply when operating between large temperature differences. Moreover, the recent Kigali amendment has raised concern about phasing out some hydrofluorocarbon refrigerants due to their impact on environment. In this paper, numerical investigation is carried compare performance of cas...
