Abstract

Binaların ısıtılması ve soğutulması için tüketilen enerjinin büyümesiyle birlikte artan endişe, ısıl performansı yüksek olan inşaat malzemelerinin ihtiyaç duyulmasına yol açmıştır. Bu amaca yönelik olarak, bu çalışmada; binalarda kullanılan çok katmanlı olan çeşitli duvar ve çatı tiplerinin kalınlık ve ısıl özelliklerinin, eksiltme faktörü, zaman gecikmesi ve ısı kazanımları gibi dinamik ısıl karakterlerine olan etkisini incelemek için bir araştırma yapılmıştır. Türkiye’ de yaygın olarak kullanılan tuğla, blokbims, gaz beton gibi bina yapılarının ısıl performans özelliklerini bulmak amacıyla MATLAB tabanlı bir bilgisayar programında kullanılan, analitik bir yöntem geliştirilmiş ve sonuçlar en uygun duvar ve çatı malzemesini belirlemek için karşılaştırılmıştır. Isı geçişi değerleri çok katmanlı yapılarda geçici rejim ısı transferi probleminin çözümü kullanılarak yapılmıştır. Isı kazancını hesaplamak için, bilgisayar programı Gaziantep’te tasarım günü için 24 saat boyunca üretilen beton numuneleri için çalıştırılmıştır. Malzemelerin termofiziksel özelliklerin sönüm oranı (DF), faz kayması (TL) ve ısı kazanımlarının üzerinde çok büyük bir etkisi olduğu çalışmanın sonucunda görülmüştür.

AN INVESTIGATION OF THE INFLUENCE OF THERMOPHYSICAL PROPERTIES OF MULTILAYER WALLS AND ROOFS ON THE DYNAMIC THERMAL CHARACTERISTICS

Abstract

The growing concern about energy consumption of heating and cooling of buildings has led to a demand for improved thermal performances of building materials. To achieve this goal, in this study, an investigation is performed to analyze the influence of thermophysical properties and thickness of various multilayer building walls or roofs in a building on the dynamic thermal characteristics, such as the decrement factor (DF), time lag (TL) and heat gain. In order to find the thermal performance characteristics of building structures, such as briquette, brick, blockbims and autoclaved aerated concrete (AAC), which are commonly used in Turkey, an analytical solution method was developed in a computer program in MATLAB and results are compared to determine suitable wall or roof material. Calculation method for the heat flow is based on solution of transient heat transfer problem for the multilayer structures. The program is executed to calculate hourly heat gain values for these samples over a period of 24 h during design day for Gaziantep, Turkey. It was found that thermophysical properties of roofs or walls have a very profound effect on the time lag (TL), decrement factor (DF) and also heat gain.
