FAZ DEĞİŞTİREN MALZEMELERİN YAPI ELEMANLARININ BASINÇ DAYANIMI VE TERMAL İLETKENLİĞE OLAN ETKİLERİ HAKKINDA LİTERATÜR ARAŞTIRMASI

Öz

Faz Değiştiren Malzemelerin (FDM) önemli alanlarından biri, bina bileşenlerinin ısı tutma kapasitesini artırmaktır. Bina bileşenlerinde enerji depolamak ve bina sıcaklık kontrolünü sağlamak için FDM'lerin ısı tutma kapasiteleri üzerinde araştırmalar yapılmaktadır. Yaz ve kış koşullarında bina sıcaklık kontrolünün sağlanması süreklilik gerektiren bir durum olduğundan, bina bileşenlerinde FDM'nin kullanılması enerji tasarrufu için önemli bir araç haline gelmiştir. Bina bileşenine sağlanan bu özellik, binanın enerji kimliğinde bir iyileşme sağlar. Genel araştırmalarda makro ve mikro kapsüllenmiş FDM kullanımı, bina bileşenlerinin ısı tutma kapasitesini artırdığı için ısı iletim katsayısını düşürür, ancak basınç dayanımını pozitif veya negatif etkiler. Ancak mikro kapsül uygulamalarında kullanılan kapsül boyutu 7 mikron ve altına düştüğünde mukavemetin arttığı, ısıl iletkenlik katsayısının düşmeye devam ettiği görülmektedir. Yapı bileşenlerinde kullanılan PCM kapsül partikül boyutları küçültüldüğünde, bileşenin granülometrisinde bir gelişme sağlar, böylece yapı bileşenlerinde mukavemet üzerinde olumlu bir etki görülür. Bu araştırma sonucunda, FDM ilavesinin makro, mikro ve nano boyutlarına ve karışım oranlarına bağlı olarak basınç dayanımında farklılıklar gözlenmiştir. Bununla birlikte, bina bileşeninin FDM oranındaki sürekli artış nedeniyle, bina bileşeninin ısı tutma kapasitesi artar ve ısıl iletkenliği azalır.

A LITERATURE REVIEW ABOUT EFFECTS of PHASE CHANGING MATERIALS on COMPRESSIVE STRENGTH and THERMAL CONDUCTIVITY of BUILDING COMPONENTS

Öz

One of the important areas of Phase Changing Materials (PCM) is to increase the heat retention capacity of building components. Researches are carried out on the heat retention capacities of PCMs to store energy in building components and to ensure building temperature control. The use of PCM in building components has become an important tool for energy saving, since ensuring building temperature control in summer and winter conditions is a situation that requires continuity. This feature provided to the building component provides an improvement in the energy identity of the building. In general researches, the use of macro, micro encapsulated PCM decreases the heat conduction coefficient as it increases the heat retention capacity of the building components, but effects compressive strength positive or negative. However, when the capsule size used in micro capsule applications is reduced to 7 microns and below, it is seen that the strength increases, while the thermal conductivity coefficient continues to decrease. When the PCM capsule particle sizes used in the building components are reduced, it provides an improvement in the granulometry of the component, so a positive effect on strength is seen in the building components. As a result of this research, differences in compressive strength were observed depending on the macro, micro and nano dimensions and mixing ratios of the pcm addition. However, due to the continuous increase in the PCM ratio of the building component, the heat holding capacity of the building component increases and its thermal conductivity decreases.
