ÖZET
Bu çalışmanın amacı, çatı geometrilerinin hangisinin yaz aylarında daha enerji verimli olduğunu belirlemek için çatı geometrisinin iç hava sıcaklığı üzerindeki etkisini düz çatılarla karşılaştırarak araştırmaktır. Bu çatı tiplerinin doğal ısı transfer katsayıları ve toplam ısı transfer katsayıları adyabatik hazne tekniği kullanılarak deneysel olarak incelenmiştir. Deneysel analiz sonucu, konik çatı dış yüzeyi doğal taşınım ısı aktarım katsayısının ve toplam ısı aktarım katsayısının düz çatılara göre sırasıyla 1,5 ve 2,5 kat daha fazla olduğunu ortaya koymuştur. Bulunan sonuçlar, yaz aylarında Harran evinde iç hava sıcaklığının daha düşük olmasının nedenleri arasındadır
