- Abstract
- Phase change materials, PCMS can be also used in thermal energy systems with various building materials in order to increase thermal performance. In this study, artificial marble with micro -encapsulated PCM (MPCM) was fabricated and its indoor environmental control and energy saving effects were analyzed using field tests in a standard Korean apartment building. The MPCM capsules contained approximately 70% n-octadecane and were fabricated using the in situ polymerization chemical method. The thermal environment was analyzed using internal tem-perature and the predicted mean cote (PMV) measurements. The results of the wall board with MPCM installed room temperature fluctuation decreased by 1-2 degrees C that it was possible to maintain a stable indoor temperature due to the thermal buffering effect. The average change of PMV was-0.03 for 12 h that no significant effect on the thermal comfort. The results of con-vection heating system energy consumption was reduced by 27.7%. Furthermore, we studied the long-term real-scale thermal performance in winter seasons.
