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 …

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 …
