WHOLE YEAR ANALYSIS OF TIM-PCM SOLAR THERMAL STORAGE WALL
Building elements with ability to adaptation to changeable external conditions is preferable in passive solar systems. Phase change material (PCM) with almost isothermal change of phase combining with transparent insulation (TIM) can be successfully used as a highly efficient, external wall system, so-called “intelligent facade”. This paper details the numerical modeling and simulation of TIM-PCM passive solar storage system with ESP-r. This partition consists of 25cm of ceramic composite modified by PCM, covered on the outside by 10cm of “honeycomb” TIM. The whole year analyses were conducted for a three-zone, highly glazed and naturally ventilated passive solar building. The behavior of TIM-PCM wall and its influence on internal wall temperature were estimated. The air, surface and resultant temperatures were compared with the “no-PCM” case and the diurnal latent heat storage effect was analyzed.
