Original Abstract

A significant problem of the utilization of renewable energy is the mismatch between the demand and availability. From this point of view heat storage contributes to renewable energy use in building heating and cooling. Heat can be stored by sensible or latent heat storage techniques. Nowadays, activated concrete structures are used as an alternative cooling and heating systems. Light-weight timber structures with equivalent heat storage capacity can be used instead of these heavy-weight structures. The latent heat storage with the use of microencapsulated Phase Change Materials (PCMs) represents a way to provide an adequate thermal mass within small thickness of thermally activated structures. A series of experiments in the lab and the test rooms have been carried out to investigate thermal behavior of microcapsulated PCMs for building applications. Microencapsulated PCM Micronal® DS 5040 X was used as latent heat storage medium in combination with gypsum plaster. The Differential Scanning Calorimetry (DSC) was used for thermal analysis of the latent heat storage medium. The storage medium underwent thermal cycling for assessment of heat storage capacity changes during proposed service life. The floor structure and the plasterboards fixed on the ceiling and walls of the experimental room with integrated PCMs were thermally activated by capillary tubes. The performance of the system was continuously observed and evaluated.
