Yükseköğretim sınıflarında iç ortam sıcaklığı ve bağıl nem düzeyinin analizi: Balıkesir Üniversitesi Örneği

Öz

Sınıflarda, öğrencilerin bilgiyi algılamasına ve işlemesine yardımcı olmak için konfor koşullarının sağlanması önemli bir ihtiyaçtır. Bu nedenle yapı fiziği açısından doğru bina ve mekan tasarımları gerekmektedir. Aksi takdirde eğitim binalarında konforsuz iç mekanlar oluşabilir ve gereksiz enerji tüketimi gerçekleşebilir. Bu çalışma, Balıkesir üniversitesinin doğal olarak havalandırılan beş sınıfında iç ortam sıcaklık ve bağıl nem değerlerini kullanarak ısıl konforu değerlendirmeyi amaçlamaktadır. Kullanım içi ve dışı saatler dahil olmak üzere parametreler iki aylık süre boyunca 15 dakika aralıklarla kaydedilmiştir. Daha sonra bu veriler excel ve spss programları aracılığıyla istatiksel olarak analiz edilmiş ve uluslarası standartlar ile karşılaştırılmıştır. Elde edilen sonuçlara göre sıcaklık değerleri Şubat ayında ısıtma sistemi nedeniyle genellikle 22-25⁰C aralığında seyretmiştir. Mayıs ayında ise iç ortam sıcaklıkları çoğunlukla 25⁰C’nin üzerine çıkmıştır. Bağıl nem değerleri her iki ayda da ASHRAE Standardı 62.1–2007’da önerildiği gibi %65 sınır değerini önemli ölçüde aşmamaktadır. Ayrıca sınıflar arasında sıcaklık değişimin de anlamlı farkların olduğu bulunmuştur (p <0.05).

Analysis of indoor temperature and relative humidity level in higher education classes: Balıkesir University Example

Öz

It is an important need that classrooms provide comfortable learning environments to help students perceive and process information. For this reason, correct building and space designs are required in terms of building physics. Otherwise, uncomfortable interior spaces and unnecessary energy consumption will occur in educational buildings. This study aims to evaluate thermal comfort by using indoor temperature and relative humidity values in five naturally ventilated classes of Balıkesir University. The parameters, including the hours in and out of use, were recorded at 15-minute intervals over a two-month period. Later, these data were analyzed statistically through Excel and SPSS programs and compared with international standards. According to the results, temperature values were generally in the range of 22-25⁰C in February due to the heating system. In May, indoor temperatures mostly exceeded 25°C. Relative humidity values do not significantly exceed the 65% limit value every two months, as recommended in ASHRAE Standard 62.1-2007. It was also found that there are significant differences in temperature change between classes (p <0.05).
