Abstract

The purpose of this study is to present thermodynamic analysis results of the solar pond, photovoltaic and wind based multigeneration energy production system for electricity and hydrogen production. The relationships between thermodynamic losses and energy and exergy efficiencies are investigated. Thermodynamic analysis performed in this paper contains exergy analyses of solar pond, photovoltaic and wind turbine subsystems. Energy efficiencies of solar pond, wind turbine, photovoltaic subsystem, organic Rankine cycle, PEM fuel cell and wholes system are 56%, 59%, 31%, 16%, 29% and 62%, respectively. On the other hand exergy efficiencies of solar pond, wind turbine, photovoltaic subsystem, organic Rankine cycle, PEM fuel cell and wholes system are 40%, 38%, 17%, 25%, 27% and 46%, respectively. The ratio of exergy consumption to exergy efficiency of integrated system is highly dependent to environment temperature, solar radiation flux and wind speed, however the effect of exergy difference on solar pond is very low.

Özet

Bu çalışmanın ana amacı, elektrik ve hidrojen üretim-depolama uygulamaları için güneş havuzu, fotovoltaik güneş sistemi ve rüzgar türbini destekli çok fonksiyonlu sistemin termodinamik analizini sunmaktır. Entegre sistem bileşenleri için enerji ve ekserji verimliliği ile termodinamik kayıplar arasındaki ilişkiler incelenmiştir. Termodinamik analiz güneş havuzu, fotovoltaik ve rüzgar türbini sistemlerinin ekserji analizlerini içeren entegre sistemin bileşenlerini kapsamaktadır. Enerji analizine bağlı olarak yaklaşık enerji verimlilikleri sırasıyla, güneş havuzunda %56, rüzgar türbininde %59, fotovoltaik sistemde %31, organik Rankine çevriminde (ORC) %16, proton değişimli membran yakıt hücresinde (PEMFC) %29, tüm sistem için maksimum enerji verimi %62 ve ekserji analizine bağlı olarak ekserji verimlilikleri sırasıyla, güneş havuzunda %40, rüzgar türbininde %38, fotovoltaik sistemde %17, organik Rankine çevriminde %25, proton değişimli membran yakıt hücresinde (PEMFC) %27, tüm sistem için maksimum ekserji verimi %46 olarak hesaplanmıştır. Entegre sitemin ekserji tüketiminin ekserji verimliliğine oranının ortam sıcaklığına, güneş radyasyonu akısına ve rüzgar hızına son derece bağlı olduğu; fakat güneş havuzu tabakalarının ekserji farkından az etkilendiği bulunmuştur.
