In this paper a gas turbine power plant including air preheater (recuperator), heat recovery steam generator and air cooler system was modeled. Eight parameters were selected as the design variables.  Fast and elitist non-dominated sorting genetic algorithm (NSGA-II) was applied (to maximize the exergy efficiency and to minimize the total cost rate) for the mentioned cogeneration system. Th...

Facing the growing pressure of climate change and environmental protection, integrated energy systems (IESs), which comprise different sources, have become promising candidates for future systems. However, capacity configuration each source remains challenging due to various couplings, randomness renewables numerical optimization difficulty. In this paper, a hierarchical framework is proposed d...

The low efficiency of Collectors that absorb energy can be mentioned as one the drawbacks in solar cogeneration cycles. In present study, systems have been improved by adding porous media and Nanofluid to collectors. One advantage using nanomaterials is more while surface area reduced. this first, collectors are enhanced 90% porosity copper combined cooling, heating power (SCCHP). Second, diffe...

In Europe, the energy consumed for heating and cooling purposes by hospitality sector is significant. island economies such as that of Mediterranean Island Malta, where Tourism considered essential to local economy, consumption perhaps even more significant, energy-efficient systems, or use renewable energy, are often listed possible solutions counter this. Based on this premise, research conta...
