Abstract
Duvar içindeki sıcaklık dağılımının bilinmesi, yoğunlaşmanın nerede olabileceğinin ve dolayısıyla nasıl önlem alınabileceğinin tespiti açısından önemlidir. Bu çalışmada, sonlu elemanlar yöntemi kullanılarak Türkiye’nin farklı iklimsel bölgelerindeki şehirler (1. bölge: Antalya, 2. bölge: Samsun, 3. bölge: Ankara ve 4. bölge: Erzurum) için kümeslerdeki farklı duvar tiplerindeki (tuğla, Ytong ve beton duvar) sıcaklık dağılımları belirlenerek, hangi yüzeylerde yoğunlaşma olabileceği tespit edilmiştir. Çalışmada iç ortam sıcaklığının 20 ºC, bağıl nemin %60 ve çiğ noktası sıcaklığının 12.04 ºC olduğu varsayılmıştır. Elde edilen sonuçlara göre dış ortam sıcaklıkları diğer şehirlere göre daha soğuk olan (6.30 ve -0.50 ºC) Ankara ve Erzurum illerinde gizli yoğunlaşma daha yoğun olarak görülmüştür. Gizli yoğunlaşmayı önlemek için duvarın sıcak tarafına buhar kesici malzemelerin yerleştirilmesi uygun olacaktır.

Determination of Hidden Condensation on The Exterior Walls of The Poultry Farm Using Finite Element Method
Abstract
The knowledge of temperature distribution within a wall is important to determine where condensation may occur and what precautions to take. This study used the finite element method to simulate the temperature distributions in different types of walls (solid brick, Ytong, concrete wall) for poultry farms in cities in different climatic regions of Turkey (1st zone: Antalya, 2nd zone: Samsun, 3rd zone: Ankara and 4th zone: Erzurum) and identify on which surfaces condensation could occur. The study assumed an indoor temperature of 20 ºC, a relative humidity of 60%, and a dew point temperature of 12.04 ºC. According to the results, hidden condensation was more common in Ankara and Erzurum, where the outdoor temperatures (6.30 and -0.50 ºC, respectively) are colder than in the other two cities. Therefore, it would be appropriate to install vapor barrier materials on the warm side of the walls to prevent hidden condensation.
