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 …

energetic, exergetic, economic and environmental evaluations (4E analysis) are performed and a multi-objective optimization … conflicting objectives including total exergetic efficiency and total cost rate of the system in multi-objective optimization are …

The chemical exergy … flows were found to be much larger than the physical exergy consumed in all the industrial bread chains studied. The par ….2%), the lowest specific exergy losses (5.4 MJ/kg brown bun), and the almost lowest cumulative exergy losses (4768MJ/1000 kg of …

This study reports the results of exergy, economic and environmental analyses of simple and combined heat and power …

All flows of exergy were allocated to an end use such as providing heat, light, transport, human and animal … work and electrical power. For each end-use we estimated a time dependent efficiency of conversion from exergy to useful …

A new definition of the exergy efficiency for two types of Sorption Heat Pumps (type I or conventional heat pump and … type II or heat transformer) is presented. It is based on the concept of transiting exergy which permits the quantitative … and non ambiguous definition of the useful exergy produced in each of these systems and exergy expended to accomplish the …
