Bandırma’da Tavuk Çiftliklerinin Dış Duvarları İçin Optimum Yalıtım Kalınlığının Araştırılması

Abstract

Bandırma ekonomisinde tavukçuluk tesisleri önemli bir yer tutmaktadır. Bu çalışmada Bandırma’da bulunan tavuk tesisi binaları dış duvarları için optimum yalıtım kalınlığı, enerji tasarrufu, geri ödeme süresi ve CO2 emisyonları araştırılmıştır. Beş farklı yakıta (doğalgaz, kömür, LPG, fuel oil ve elektrik) göre hesaplamalar yapılmıştır. İki farklı yalıtım malzemesi(Expanded Polistren ve Extruded Polistren) kullanılmıştır. Yaşam döngüsü maliyet analizi (LCCA) metodu uygulanmıştır. Hesaplamalarda temel alınan denge sıcaklığı, etlik piliçlerin 6 haftalık üretim sezonu boyunca ihtiyaç duyduğu sıcaklık değerleri (Ttemel =31, 29, 25, 23.50, 22.50 ve 20.50°C) dir. Bu denge sıcaklıklarına göre hesaplanan derece gün değerleri ısıtma için 3111, soğutma için 79 olarak elde edilmiştir. Sonuçlarda, optimum yalıtım kalınlığının ısıtmada 0.065-0.233 aralığında değiştiği görülmektedir. Tasarruf miktarı ve geri ödeme süresi ise sırasıyla 17.75-122 $/m2 ve 1.72-1.20 yıl aralığında değişmektedir. Optimum yalıtım kalınlığı uygulanması durumunda yakıt miktarında ve CO2 emisyonlarında ise %80-90 oranında azalma sağlanabileceği hesaplanmıştır. Bu çalışma ile Bandırma'nın tavukçuluk sektöründe önemli bir yer kazanmasına katkıda bulunmak amaçlanmıştır.

Investigation of Optimum Insulation Thickness for External Walls of Poultry Farms in Bandırma

Abstract

Poultry plants have an important place in the economy of Bandırma. This study examined the optimum thickness of insulation, energy saving, payback period, and emissions of CO2 for poultry plant buildings' external walls in Bandırma. Calculations were based on five various fuels (natural gas, coal, LPG, electricity, and fuel oil). This study used two various insulation materials (Expanded Polystyrene and Extruded Polystyrene) were used. The Life Cycle Cost method has been applied as the approach. The equilibrium temperature, on which the calculations were based, was the temperature values required by broilers during the 6-week production season (Tbase= 31, 29, 25, 23.50, 22.50 and, 20.50°C). The degree day values calculated according to these equilibrium temperatures were obtained as 3111 for heating and 79 for cooling. The results showed that the optimum thickness of insulation varied in the range of 0.065-0.233 in heating. The amount of savings and payback period vary between 17.75-122 $/m2 and 1.72-1.20 years, respectively. It was calculated that a reduction by 80-90% in fuel quantity and CO2 emissions could be achieved after application of the optimum insulation thickness. This study aims to contribute to Bandırma's becoming an important place in the poultry sector.
