Öğe Farklı duvar ve yakıt tiplerinde optimum yalıtım kalınlığının ısıtma ve soğutmada tespiti ve çevresel etkileri(Fırat Üniversitesi, 2016-09-06) Karakaya, HakanGelişen teknoloji ve artan nüfus, enerjiye olan talebi günden güne artırmaktadır. Bu durum Türkiye gibi gelişmekte olan ülkeleri zorunlu enerji tasarrufuna yöneltmiştir. Yapılarda enerji israfı için kullanılan en etkin yöntemlerden biri ısı yalıtımıdır. Bu çalışmada dört farklı duvar tipi (tuğla, izo-tuğla, bims blok ve gaz beton) için farklı yakıt (doğalgaz, kömür, fuel-oil ve elektrik) ve yalıtım (xps ve eps) türleri kullanılarak ısıtmada ve soğutmada optimum yalıtım kalınlığı, toplam maliyet, enerji tasarrufu, geri ödeme süresi ve çevresel analizi yapılmıştır. Yıllık kazanç oranı optimum noktada yalıtımsız duruma göre ısıtmada sırasıyla % 38.20, % 55.31, % 30.19 ve % 85.10 iken soğutmada % 54,52, % 75,62, % 43,76 ve % 98,92 olmuştur. Geri ödeme süresi ısıtmada sırasıyla 2 yıl, 3,11 yıl, 1,54 yıl ve 5,88 yıl olurken soğutmada 3,03 yıl, 4,68 yıl, 2,30 yıl ve 8,79 yıl değerlerini almıştır. Çevreye salınan CO2 ve SO2 emisyonlarında yalıtımsız duruma oranla optimum noktada % 77,30 civarında azalma gözlenerek kayda değer miktarda fayda sağlanmıştırÖğe Environmental and economic analysis of optimum heat insulation thickness in energy saving(European Journal of Technique (EJT), 2016-08-01) Karakaya, Hakan; Kallioğlu, Mehmet Ali; Arca Batı, Zülal; Durmuş, AylaDeveloping technology and increasing population cause the natural energy resources rapidly. This has compulsorily forced the countries such as Turkey, which import almost all energy needs and use great deal of it in home heating, to save energy. It will provide benefits for users, indirectly the economy of the country, with saving obtained from insulation. One of the most effective methods attaining gain of energy is heat insulation. While heat insulation is carried out, by determining the optimum efficiency point, the amount of fuel used decreases, which leads to cost reduction and highest efficiency level. Therefore, it is possible to tolerate harmful emissions. In this study, optimum insulation thickness, total cost, energy saving, duration of pay-back and environmental analysis for heating were conducted in Diyarbakır by utilizing different fuel and insulation types. When extruded polystyrene (XPS) was used, average optimum thickness was 0,0675 (m), annual return was 62,165%, duration of pay back was 1,83 (years) and CO2 and SO2 emissions were 76% lesser. When expanded polystyrene (EPS) was used, the parameters such as average optimum thickness 0,0825 (m), annual return 73,06%, duration of pay back 1,245 (years) and CO2 and SO2 emissions 85% lesser.Öğe Environmental and economic analysis of optimum heat insulatıon thickness in energy saving(Dicle University, 2016) Kallioğlu, Mehmet Ali; Karakaya, Hakan; Arca Batı, ZülalDeveloping technology and increasing population cause the natural energy resources rapidly.
