Abstract

This article presents the possibilities of using phase change materials for the modernization of transparent partitions and elements functioning with them. The author draws attention to the possibility of reducing the energy costs of the building, by increasing the thermal capacity of the internal window blinds. The article draws attention to many factors related both to the properties of PCMs themselves, the place of application and climatic conditions that may affect the effectiveness of the entire solution. To assess the energy efficiency of the abovementioned shutter, field tests were carried out in an isothermal test chamber. The article presents the results of the conducted research, showing the advantages and disadvantages of the considered solution. A large number of scientific papers, in which the possibilities of using phase change materials for the modernization of transparent partitions are presented, apply only to the modernization of glazing. In this context, this work presents a different approach to the issues of using phase change materials in construction.
