- Abstract
Phase Change Materials (PCM) provide renewable and sustainable energy, especially by storing renewable energy sources that are not always available and enabling them to be used when demanded. Since PCMs cannot meet the desired thermodynamic, kinetic, chemical and economic properties in thermal energy storage alone, they are supported by different nanomaterials. There are critical parameters for the selection of nanomaterials used to improve the properties of PCM, and in this study, it is aimed to prioritize inorganic nanomaterials. At this point, the Multi Criteria Decision Making (MCDM) methodology is very useful. In this study, Multi-Objective Optimization Method Based on Ratio Analysis (MULTIMOORA) was used to prioritize 5 different inorganic nanomaterials (copper oxide, aluminum oxide, silver, titanium oxide and boron nitride) that can be used in PCMs. Six evaluation criteria were determined as melting point change, latent heat change, thermal conductivity change, pretreatment requirement, toxicity and cost. The criteria weights were determined by entropy (objective method) and ranking (subjective) methods, respectively. According to the weighting method of both criteria, the melting point change was determined as the most important criterion. According to MULTIMOORA results, boron nitride (BN) was found to be the most suitable inorganic nanomaterial to be added to PCMs.
