Abstract
Phase Change Materials (PCMs) offer new opportunities to optimise thermal mass. The melting temperature is a key aspect of PCM selection, which can be characterised by the melting-peak temperature Tmp and the melting temperature range ∆Tm. WhileTmp has been studied extensively, little research has focused on ∆Tm. This study investigates the optimal combination (Tmp, ∆Tm) by simulating a test-cell based on a nearly zero-energy office building in a temperate climate. Our results show that the optimal Tmp varies slightly with ∆Tm for heating and cooling energy demand indicators while aggregated indicators can be more influenced by ∆Tm. This research project has been funded by FEDER and Wallonia in the framework of the operational programme Wallonie-2020.EU.
