evaluation through energy and exergy efficiencies. The solar pond system is filled with magnesium chloride containing water to … the temperature sensors. The energy and exergy content distributions are determined for the heat storage zone and the non …-convective zone. The maximum exergy destructions and losses appear to be 79.05 MJ for the heat storage zone and 175.01 MJ for the non …

preparation in the tank is accomplished. From the experimental results, correlations between exergy destruction and the standing … it is deduced that in order to minimize the cost of exergy destruction in a two stage discharging regime, the initial …

For each end-use we estimated a time dependent efficiency of conversion from exergy to useful …-2000) trends in resource exergy supply and conversion to useful work in the United Kingdom. The exergy resources considered … (including biomass). All flows of exergy were allocated to an end use such as providing heat, light, transport, human and animal …

A new definition of the exergy efficiency for two types of Sorption Heat Pumps (type I or conventional heat pump and … given operations. Finally the direct relationships between coefficient of performance and exergy efficiency of heat pump and … type II or heat transformer) is presented. It is based on the concept of transiting exergy which permits the quantitative …

In this paper, an energy and exergy analysis is performed on four different wind power systems, including both … variables are analyzed and the predicted results are discussed. The exergetic efficiency of each wind turbine is studied for …
