- Abstract
In this study, the effects of using hybrid PCM inside the wall on reducing heat transfer have been examined during the hottest (July) and coldest months (January) in three climate zones. The base wall thickness was 20 cm, and PCM-based wall thickness was considered to be 22 cm. The PCM was placed in two separate layers of 1 cm within the wall. The objective function was to diminish the heat transfer from the PCM-base wall, as compared to the base wall. In all three climatic zones, in warm and cold months, PCM loading into the wall leads to heat transfer reduction. Based on numerical results, in climate zones A (hot summer and mild winter), B (mild summer and very cold winter) and C (warm summer and cold winter) owing to using hybrid PCM layers, heat transfer diminished by 26.9%, 29.65% and 30.5%, respectively.
