The difference in the effect of phase change materials on the heating and cooling needs of office spaces on the ceiling, floor, interior, and exterior walls in Tehran

Abstract

Introduction: Given the criticality of energy consumption and the reduction of fossil fuel resources, and the fact that the energy consumption of buildings for heating and cooling includes a significant amount of fuel consumption, one of the ways to deal with this situation is to maintain and prevent energy waste. According to research, one of the newest and most effective technologies in this regard is the use of phase change materials, or PCMs, which can be used in various components and parts of the building.

Research Method: Using energy simulation software in buildings is one of the most reliable methods of finding out the effect of phase change materials in a building. In the present research, an attempt has been made to identify the best phase change material with the best thickness and location in the ceiling, floor, exterior and interior walls, and the most effective of them, using Design Builder software, which is based on the Energy Plus engine.

Results and Discussion: In this study, after simulating the desired building in Design Builder, the wall components were simulated. Then, the phase change material was placed in different layers of the interior and exterior walls, ceiling, and floor to determine the best location for it. Then, the different melting points of the phase change material were examined in the best location. Finally, the effect of the thickness of these materials on the cooling and heating of the building was examined, and the highest effect among them was determined.

Conclusion: According to the results of the simulations in the cases with and without phase change materials, it can be concluded that these materials have a positive effect on reducing energy consumption in cooling and heating the building.
