Capric–myristic acid/expanded perlite composite as form-stable phase change material for latent heat thermal energy storage

Karaipekli, Ali; Sarı, Ahmet - In: Renewable Energy 33 (2008) 12, pp. 2599-2605

The aim of this study is to prepare a novel form-stable phase change material (PCM) for latent heat thermal energy … perlite (EP). Thermal properties, thermal reliability, and thermal conductivity of the form-stable composite PCM are … determined. The maximum CA–MA absorption of EP was found to be 55wt% without melted PCM seepage from the composite, and therefore …
