This paper deals with the experimental investigation of a magnesium chloride saturated solar pond and its performance evaluation through energy and exergy efficiencies. The solar pond system is filled with magnesium chloride containing water to form layers with varying densities. A solar pond...

In this paper, exergy method is applied to analyze the gas turbine cycle cogeneration with inlet air cooling and evaporative aftercooling of the compressor discharge. The exergy destruction rate in each component of cogeneration is evaluated in detail. The effects of some main parameters on the...

Both thermoeconomic modeling and multi-objective optimization studies are undertaken for a novel integrated multigeneration system, containing a biomass combustor, an organic Rankine cycle to produce electricity, a double-effect absorption chiller for cooling, a heat exchanger, a proton exchange...

The solidification process in encapsulated ice thermal energy storage (EITES) system is simulated for water-filled capsules while neglecting storage tank wall effects and heat penetration. Energy and exergy efficiencies were calculated while varying capsule shape, inlet Heat Transfer Fluid (HTF)...

A comprehensive thermodynamic modeling and optimization is reported of a polygeneration energy system for the simultaneous production of heating, cooling, electricity and hot water from a common energy source. This polygeneration system is composed of four major parts: gas turbine (GT) cycle,...

A new multi-generation system based on a biomass combustor, an organic Rankine cycle (ORC), an absorption chiller and a proton exchange membrane electrolyzer to produce hydrogen, and a domestic water heater for hot water production, is proposed and thermodynamically assessed. Exergy analysis is...
