Optimum Yalıtımı Kalınlığının Enerji Tasarrufu ve Küresel Isınma Potansiyeli Üzerine Etkisi

Abstract

Dış yüzeylerde meydana gelen ısı kayıplarını azaltmanın en etkili yöntemi ısı yalıtımıdır. Bu çalışmada, Diyarbakır ili için farklı yakıtlara göre optimum yalıtım kalınlığı, enerji tasarrufu, maliyet tasarrufu, geri ödeme süreleri ve sera gazı emisyonları hesaplanmıştır. Hesaplamalar üç farklı yakıt (doğalgaz, kömür ve fuel-oil) dikkate alınarak yapılmıştır. Optimum yalıtım kalınlığı, yaşam döngüsü maliyet yöntemi kullanılarak hesaplanmıştır. Küresel ısınma potansiyeli, kg CO2 eşdeğer (CO2eq.) olarak ifade edilmiş ve yaşam döngüsü değerlendirme yöntemi ile belirlenmiştir. Doğalgaz, kömür ve fuel-oil için optimum yalıtım kalınlığı sırasıyla 0.057 m, 0.066 m ve 0.089 m olarak bulunmuştur. Geri ödeme süreleri doğalgaz, kömür ve ful petrol için sırasıyla 2.85, 3.57 ve 2.05 yıl olarak hesaplanmıştır.. Hesaplanan optimum yalıtım kalınlıkları için yıllık önlenen çevresel etkiler doğalgaz, kömür ve fuel-oil için sırasıyla 17.45, 51.28 ve 26.7 kg CO2eq /m2 olarak bulunmuştur.

The Effect of Optimum Insulation Thickness on Energy Saving and Global Warming Potential

Abstract

The most effective method of reducing heat losses occurring on the outer surfaces is thermal insulation. In this study, optimum insulation thickness, energy saving, cost saving, payback period and greenhouse gas emissions were calculated with respect to different fuels for Diyarbakır province. The calculations were performed considering three different fuels (natural gas, coal and fuel-oil). The optimum insulation thickness was calculated using the life cycle cost method. Global warming potential is expressed as kg CO2 equivalent (CO2eq.) and calculated by life cycle assessment method. The optimum insulation thickness was found as 0.057 m, 0.066 m and 0.089 m for natural gas, coal, and fuel oil respectively. Payback periods were calculated as 2.85, 3.57 and 2.05 years for natural gas, coal and fuel oil, respectively. Annual avoided environmental impacts for calculated optimum insulation thicknesses were found as 17.45, 51.28 and 26.7 kg CO2eq/m2 for natural gas, coal, and fuel oil respectively.
