Resumo

This work is to study a dual-channel and thermal-insulation-in-the-middle type solar PCM storage wall (MSPCMW) system. The system has the following four independent functions: passive solar heating, heat preservation, heat insulation, and passive cooling, and it can agilely cope with the requirements of climatization of buildings in different seasons throughout the year, and are exactly suitable for building in regions characterized by hot summer and cold winter. Based on the previous work, the present work deeply experimentally analyzes thermal feature of the PCM plates for the system working in summer and winter modes respectively. The results show that the temperature of the upper position of PCM plate is higher than that of the lower position and the temperature difference between exterior and interior surfaces of PCM plates are small in summer and winter mode. It indicates that the temperatures of PCM plates have a stratification phenomenon along height and the encapsulated PCM has little temperature gradient through thickness direction.
