ISIL ENERJİ DEPOLAMA SİSTEMLERİ İÇİN ORGANİK FAZ DEĞİŞTİREN MADDELERİN MEVCUT DURUMU ÜZERİNE BİR İNCELEME

Abstract

Gizli ısıl enerji depolama son yıllarda önemle üzerinde durulan, enerji verimliliğini artırıcı yöntemlerden biridir. Gizli ısıl enerji depolamada kullanılan yüksek ısıl kapasiteye sahip ve belirli bir sıcaklık değerinde faz değiştirerek enerji absorblayan veya salan maddelere Faz Değiştiren Maddeler (FDMler) adı verilir. FDMler organik, inorganik ve ötektik bileşikler olmak üzere üç ana grupta toplanır. Organik FDMler katı-sıvı faz değişimi gösterirken küçük hacim değişimine uğramaları ve yüksek gizli ısıl enerji depolama kapasitesine sahip olmalarından dolayı diğer FDMlere göre daha çok tercih edilmektedir. Kapsülleme çalışmaları organik FDMlerin ısı transfer alanını artırmak ve faz değişimi sırasındaki hacim değişimini kontrol altında tutmak amaçlı yapılmaktadır. Ayrıca organik FDMlere nano yapıda malzemelerin ilave edilmesi ısıl iletkenliğin artırılmasını sağlamaktadır. Bununla birlikte, ısıl davranışların incelenmesi için yapılan modelleme çalışmaları ile organik FDMlerin kullanımı giderek yaygınlaşmaktadır. Bu çalışmada, son 20 yılda organik FDMlerin kapsüllenmesi, ısıl iletkenliğinin artırılması ve ısıl davranışının modellenmesi konusunda yapılan araştırmaların sonuçları sunulmuştur.

A REVIEW ON CURRENT STATUS OF ORGANIC PHASE CHANGE MATERIALS FOR THERMAL ENERGY STORAGE SYSTEMS

Abstract

Latent heat energy storage is one of the energy efficiency enhancing methods that has been emphasized in recent years. Materials used for latent heat storage having high storage capacity and absorbing and emitting heat by changing phase at a certain temperature are called phase change materials (PCMs). PCMs classify in three main groups: organic, inorganic, and eutectic. Organic phase change materials are mostly preferred than the other phase change materials due to the fact that they possess small-volume changes during the solid-liquid phase change process and higher latent heat of fusion. Encapsulation studies are carried out to increase the heat-transfer area for organic PCMs and to preserve volume change during phase change. Furthermore, the addition of the nano-structured materials into the organic phase change materials provides that the thermal conductivity be increased. At the same time, the use of organic phase change materials is becoming increasingly widespread with modeling studies on the thermal behavior analysis.

In this study, a review of researches on encapsulation of organic phase change materials, thermal conductivity enhancement and modeling of thermal behavior reported in the last 20 years has presented.
