Ağrı İlinde Farklı Yakıtlar ve Duvar Bileşenleri İçin Optimum Yalıtım Kalınlıkları Kullanılarak Enerji Maliyetlerinin Analizi

Öz

Isı yalıtımı konusu global ölçüde önem arz eden ve üzerinde sürekli çalışılan bir alanı oluşturmaktadır. Bu bağlamda, Ağrı ili için dört farklı duvar modeli (taş, tuğla, briket ve betonarme) ve beş farklı yakıt (kömür, doğalgaz, Likit Propan Gaz (LPG), fuel oil ve elektrik) çeşidi seçilerek optimum yalıtım kalınlığı, yalıtım maliyeti, yakıt ve toplam maliyetler, geri ödeme süresi ve yıllık enerji kazancı değerleri hesaplanmıştır. Çalışmada yalıtım malzemesi olarak Genleştirilmiş Polistiren (EPS) kullanılmıştır. En yüksek optimum yalıtım kalınlığı, yakıt maliyeti ve toplam maliyet değerleri elektrik enerjisinin kullanıldığı durumda betonarme duvar modeli için belirlenmiştir. Betonarme duvar modelinde elektrik enerjisi için optimum yalıtım kalınlığı 0.168 m, yakıt maliyeti 3,2392 $/m2 ve toplam maliyet 23,9826 $/m2 olarak tespit edilmiştir. Betonarme duvar modeli için optimum yalıtım kalınlığı, yakıt maliyeti ve toplam maliyet diğer duvar türlerine göre daha yüksek değerler gösterse de geri ödeme süresi bakımından en verimli duvar modeli olduğu belirlenmiştir. Kullanılan yakıt çeşitleri arasında geri ödeme süresi bakımından en verimli olanının elektrik, kömür ve doğal gazın kendilerini en geç amorti edebilen iki yakıt çeşidi olduğu belirlenmiştir.

Analysis of Energy Costs Using Optimum Insulation Thicknesses for Different Fuels and Wall Components in Ağrı Province

Öz

The subject of thermal insulation constitutes an area that is of global importance and is constantly studied. In this context, by choosing four different wall models (stone, brick, briquette and reinforced concrete) and five different fuels (coal, natural gas, Liquid Propane Gas (LPG), fuel oil and electricity) for Ağrı province, optimum insulation thickness, insulation cost, fuel and total costs, payback period and annual energy gain values were calculated. Expanded Polystyrene (EPS) was used as insulation material in the study. The highest optimum insulation thickness, fuel cost and total cost values were determined for the reinforced concrete wall model in the case where electrical energy was used. In the reinforced concrete wall model, optimum insulation thickness for electrical energy was determined as 0.168m, fuel cost was 3,2392 $/m2 and total cost was 23,9826 $/m2. Although the optimum insulation thickness, fuel cost and total cost for the reinforced concrete wall model were higher than the other wall types, it has been determined that it was the most efficient wall model in terms of payback time. It has been determined that among the fuel types used, the most efficient in terms of payback period are electricity, coal and natural gas, the two fuel types that can amortize themselves at the latest.
