Possibilities of using phase change material in building structures

Popis výsledku v původním jazyce

The primary objective of this study is to calculate heat losses due to thermal transmission and the accumulation of thermal energy in a model multi-layered flat external wall assembly. The analysis is conducted for three fundamental material configurations, representative of common thermal insulation solutions, as well as for their combinations with a phase change material (PCM) based on wax paraffins, exhibiting a phase transition at 27 °C. The calculations provide a basis for further development and application in the design of energy-efficient building envelopes, particularly with regard to thermal performance optimization, selection of appropriate heat sources, and the design of heating systems.In addition to steady-state thermal analysis, the study introduces a transient numerical model developed in the ANSYS Fluent software environment. This model simulates heat transfer behavior under dynamic boundary conditions, with a particular focus on summer operation scenarios. Two types of external plasters were evaluated: a conventional plaster and a plaster modified with PCM additives. The incorporation of PCM is intended to enhance the thermal inertia of the envelope, allowing better utilization of solar gains while reducing the cooling demand and operational energy costs associated with air conditioning systems.
