Abstract

In this study, the various thermal comfort parameters including temperature, relative humidity, air velocity, metabolic activity and clothing resistance and their effect to each other are examined. The heat transfer equations given for steady stale energy balance between body and environment and the empirical equations which give thermal comfort and physiological control mechanisms of body are used. According to the ASHRAE Standard 55-1992, an environment can be assumed comfortable while Predicted Percentage of Dissatisfied (PPD) is less than % 10. Considering this, thermal comfort zones in various conditions are studied and results are presented and discussed.

Özet

Bu çalışmada, sürekli rejim enerji dengesi modeli için verilen, vücut ile çevre arasındaki ısı geçişi denklemlerinden ve ısıl konfor ile vücuttaki fizyolojik kontrol mekanizmalarının etkilerini ifade eden ampirik bağıntılardan yararlanarak, insanların ısıl konfor şartlarını etkileyen sıcaklık, bağıl nem, hava hızı, metabolik aktivite ve giysi yalıtım dirençleri gibi parametrelerin değişimi ve birbirine etkileri incelenmiştir. ASHRAE Standart 55 - 1992'nin vermiş olduğu, bir ortamın konforlu olarak nitelendirilebilmesi için memnun olmayanların yüzdesinin (PPD) % 10'u aşmaması gerektiği göz önünde tutularak insanların farklı şartlarda konforlu hissedebilmeleri için ısıl konfor bölgeleri çıkarılmış ve sonuçlar grafikler halinde sunulmuştur.
