Yumurta tavuğu kümeslerinin dış duvarları için optimum yalıtım kalınlığının belirlenmesi

Bir ülkenin enerji stratejisinin temel hedeflerinden biri de enerji tasarrufudur. Isı yalıtımı enerjinin korunumun da önemli bir yere sahiptir. Bu nedenle, bu çalışma da Türkiye’de en fazla yumurta tavuğu yetiştiren on il için optimum yalıtım kalınlığının belirlenmesi amaçlanmıştır. Derece gün yöntemi kullanılarak yıllık ısıtma ve soğutma yükleri belirlendikten sonra taş yünü (RW) ve cam yünü (GW) yalıtım malzemeleri için optimum yalıtım kalınlığı, enerji tasarrufu, geri ödeme süreleri ve CO2 emisyonları hesaplanmıştır. Sonuç olarak şehir ve yakıt türüne bağlı olarak RW yalıtım malzemesi için optimum yalıtım kalınlığının 0.046 ile 0.165 m arasında, enerji tasarrufunun %35.42 ile %74.56 arasında ve geri ödeme süresinin 0.67 ile 2.00 yıl arasında olduğu, GW yalıtım malzemesi içinse optimum yalıtım kalınlığının 0.045 ile 0.150 m arasında, enerji tasarrufunun %42.17 ile %77.72 arasında ve geri ödeme süresinin 0.61 ile 1.72 yıl arasında değiştiği belirlenmiştir. CO2 emisyonundaki en düşük azalma oranı (%64.79) İzmir ili için doğalgaz ve RW yalıtım malzemesi kullanıldığı zaman, en yüksek azalma oranı ise (%88.76) LPG ve GW yalıtım malzemesi ile Kayseri'de elde edilmiştir.

The determination of optimum thermal insulation thickness for external walls of laying hens building

One of the main objectives of the energy strategy of any country is energy conservation. Thermal insulation is of utmost importance in the context of conservation energy. Therefore, this study aims to optimize insulation layer for the ten cities of Turkey which have the highest number of laying hens. The yearly heating and cooling loads were determined by using degree day method. Then optimum insulation thickness, energy savings, payback periods and CO2 emission were computed for Rock wool (RW) and Glass wool (GW) insulation materials. The study's results indicated that the optimum thickness of insulation for RW insulation material varies between 0.046 and 0.159 m, energy savings range between 35.42% and 74.56%, and payback periods were between 0.67 and 2.00 years, while for GW insulation material optimum insulation thickness varies from 0.450 and 0.150 m, energy savings vary in the range of 42.17% and 77.72%, and payback periods were between 0.61 and 1.72 years depending on the city, and type of fuel. The lowest CO2 emission reductions (64.79%) were obtained for İzmir with natural gas and RW insulation material are used, while the highest value (88.76%) was achieved for Kayseri with LPG and GW insulation material.
