NUMERICAL AND IN-SITU EVALUATION OF THE THERMAL COMFORT IN ROOMS WITH EMBEDDED PCM IN THE WALL CONSTRUCTION
Modern buildings have typically full glazed facades with light interior wall constructions and increasing electrical equipment inside. This leads to higher exterior and interior cooling loads. It is characteristic that these building have no thermal mass and a high cooling load. Possibilities to minimize the cooling load and to increase the thermal comfort are phase change materials (PCM). Wall constructions with PCM can increase the thermal mass. The PCM increase the heat capacity in a certain temperature band. This paper presents the work from a research project that analysis the thermal performance of PCM products in rooms. Two PCM products are evaluated (salt hydrates and paraffin). In an experimental study the room temperature and the wall fluxes are measured for different boundary conditions. The thermal comfort of a test room with or without PCM is compared. A calculation method to predict the indoor climate for rooms with PCM is derivated out from the measurements. The simulation tool is integrate in the numerical simulation environment TRNSYS 16.
