Abstract

In this study, a theoretical approach is developed for the prediction of time and temperature during the heat charge and discharge in the storing of latent heat of phase changed materials (PCM). Assuming the constant heat capacity and constant average values of PCM, obtained analytical solution is compared with the experimental results. The comparisons with experimental data related to the cooling storage by using especially small spheres are given here. Good agreement was found between theoretical and experimental results.

Özet

Bu çalışmada, faz dönüştüren malzemelerle (FDM) gizli enerji depolamada ısı yükleme ve boşaltma sırasında sürenin ve sıcaklıkların tahmini üzerine kuramsal bir yaklaşım geliştirilmiştir. FDM için sabit ortalama özgül ısı tanımı ve sabit ortalama değerler kabul edilerek elde edilen analitik çözüm değişik deneysel verilerle karşılaştırılmıştır. Burada özellikle küçük küreler kullanılarak yapılan soğu depolama ile ilgili deneysel verilerle yapılan karşılaştırmalar verilmiştir. Deneysel sonuçlarla iyi uyum gözlenmiştir.
