Latent Heat Storage Plaster: Lab-Scale Experiment and Simulation

Abstract:

Energy storage can even out mismatches between the demand and supply of energy, thereby improving the system performance and reducing the cost of building operation. The energy storage is a key issue in the wider use of renewable energy. The experiments carried out at Brno University of Technology focus on the latent heat storage techniques for application in radiant heating and cooling of residential and office buildings. The latent heat storage techniques utilize Phase Change Materials (PCMs) as a heat storage medium and thus allow for the reduction of the amount of heat storage material due to the high heat storage density per volume or weight. In the past, much attention was paid to encapsulation of PCMs. The PCMs undergo phase change from solid to liquid and vice versa during a heat storage cycle and there is a risk of leakage of the PCMs to the building material or indoor environment. The microencapsulated organic PCMs in a mixture with gypsum plaster were used in the investigations described in this paper. The investigations involved both lab-scale experiments and numerical simulations.
