Kenig* Chair of Fluid Process Engineering, Faculty of Mechanical Engineering, Paderborn University, Paderborn, Germany The thermal performance of macro-encapsulated latent heat storage elements in form of thin, rectangular plates within an air-driven heat storage system is investigated. The plates are made of high-density polyethylene and filled with phase change material. Several plates are stacked together and inserted into a box which can be installed in a heating/air conditioning system. First, an experimental test rig was designed. Measured temperature and pressure drop data retrieved from the rig was then used to validate a simplified computational fluid dynamics model describing a section of the test set-up including a stack of ten plates. Afterward, the model was reduced in complexity in order to perform a parametric study by varying geometric parameters of the storage plates. In total, 217 Edited by: Theodoros Damartzis, different geometries were simulated and their thermo-hydraulic efficiency was evaluated.
