PROPOSED TRNSYS MODEL FOR STORAGE TANK WITH ENCAPSULATED PHASE CHANGE MATERIALS
Katherine D'Avignon, Michaël Kummert
Latent heat storage (LHS) using phase change materials (PCM) is a promising avenue to resolve the frequent timing mismatch between energy supply and demand. This paper deals with the modelling and simulation of a versatile thermal energy storage tank filled with encapsulated PCMs of rectangular geometry. A simple model is implemented as a TRNSYS component un a complete building simulation to be used for selecting phase change temperature and testing control strategies. It uses the enthalpy method and assumes phase change occurs over a small temperature range. A comparison of model results to numerical results found in the literature indicates that it can predict the dynamic performance of this type of thermal energy storage (TES) tank with reasonable accuracy during loading and off-loading cycles. Further work, will aim to improve the model and validate it against experimental measurements.
