Abstract :

Nowadays, the use of phase change materials is very important to reduce energy consumption in buildings and industry structures. The use of phase change materials in the structure of buildings will be widely used in the near future. Because the presence of these materials in the building structure, such as the use in water heater cultures, will reduce the consumption of fossil energy.Phase change materials (PCM) store thermal energy in the latent heat method. These materials have a high thermal storage density and with small temperature changes, they provide an important role in saving energy and thermal insulation in the building. Materials naturally delay the transfer of heat to the building by several hours due to the reduction of indoor air temperature fluctuations and the room air temperature remaining close to the desired room temperature for a longer period of time. In order to recover heat or cold, the storage method is used. In general, there are two types of thermal energy storage systems during physical processes:1- Storage of sensible thermal energy ,2- Latent thermal energy storage. In this article, we investigated the use of phase change materials in the solar collector installed in the building. In this article, Ansys Fluent software is used for simulation. The amount of solar radiation in Iran is estimated between 1800 and 2200 kilowatt hours per square meter per year, which is higher than the world average.
