AB  - In this study, the size effects of the Graphenenanoparticles (GNP) doped into a paraffin type organic phase change material(PCM) on thermal properties were examined. The thermal conductivities,melting/solidification temperatures and melting/solidification latent heats ofthe GNP/PCM composites, which were obtained by incorporating GNP nanoparticleswith three different sizes into an organic PCM in mass fractions of 1%, 3% and5%, were measured. The changes obtained in thermal properties were determined byreferring to the non-doped PCM data. The results obtained showed that in lowPCM mass fractions, thermal conductivity enhancement was a function of bothsurface area and thickness of the GNP nanoparticles. In addition, it wasdetermined that thicker nanoparticles formed a more efficient conductionnetwork at high PCM fractions. The reflections of the enhancements obtained inthermal conductivity on thermal performance were also determined in the study. Enhancements in thermalconductivity depending on the increase in thickness of GNP were obtained as 6.3%,107.5% and 113.7% for 5% GNP(1-5nm)/ PCM, 5% GNP(6-8nm)/PCM and 5% GNP(11-15nm)/PCMcomposites, respectively. These thermal conductivity enhancements resultedperformance increase in the energy storage unit around 5.5%, 18.3% and 20%respectively.

N2  - Bu çalışmada, parafintipi bir organik Faz Değişken Malzeme (FDM) içerisine katkılanan Grafennanoparçacık boyutunun termal özellikler üzerindeki etkileri incelenmiştir. Üçfarklı boyuta sahip GNP nanoparçacıkların organik bir FDM içerisine %1, %3 ve%5 kütle bölüntülerinde katkılanması suretiyle elde edilen GNP/FDMkompozitlerinin ısıl iletkenlik, erime/katılaşma sıcaklıkları veerime/katılaşma gizli ısıları ölçülmüştür. Termal özelliklerde elde edilendeğişimler katkılanmamış FDM verileri referans alınarak belirlenmiştir. Eldeedilen sonuçlar, düşük GNP kütle bölüntülerinde ısıl iletkenlikiyileştirmesinin hem GNP nanoparçacık yüzey alanının hem de kalınlığının birfonksiyonu olduğunu göstermiştir. Buna ilave olarak, daha kalınnanoparçacıkların yüksek FDM kütle bölüntülerinde daha etkin bir iletim ağı oluşturduklarıbelirlenmiştir. Çalışmada ayrıca ısıl iletkenlikte elde edilen iyileştirmelerintermal performansa yansımaları da belirlenmiştir. GNP nanoparçacıkkalınlığındaki artışa bağlı olarak ısıl iletkenlikteki iyileşmeler; 5%GNP(1-5nm)/ FDM, 5% GNP(6-8nm)/FDM ve 5% GNP(11-15nm)/FDM kompozitleri içinsırasıyla %6.3, %107.5 ve %113.7 olarakelde edilmiştir. Bu ısıl iletkenlik iyileştirmeleri, bir enerji depolamabiriminde sırasıyla %5.5,% 18.3 ve % 20 civarında performans artışısağlamıştır.
