چکیده
افزایش بی رویه قیمت و میزان مصرف انرژی در کشورهای مختلف و اهمیت روزافزون حفظ محیط زیست و منابع انرژی تجدید ناپذیر، پژوهشگران را بر آن داشته تا با تبیین شیوه های نوین، راهکارهایی به منظور صرفه جویی در مصرف انرژی در حوزه های گوناگون ارائه دهند. یکی از مواردی که این روزها بیش از پیش مورد توجه پژوهشگران قرارگرفته است، استفاده از مواد تغییر فاز دهنده در حوزه مواد و مصالح ساختمانی است. این در حالی است که در ایران تحقیقات گسترده ای پیرامون این حوزه صورت نگرفته است. در طرح حاضر بنا داریم تا تاثیر استفاده از این مواد را در میزان انتقال حرارت یک دیوار در چهار حالت مختلف به مدت یک سال بررسی نماییم. حالت اول میزان انتقال حرارت از دیوار بدون مواد تغییر فاز دهنده، حالت دوم میزان انتقال حرارت از دیوار با مواد تغییر فاز دهنده، حالت سوم میزان انتقال حرارت از دیوار با مواد تغییر فاز دهنده با ساختار لتیسی BCC و حالت چهارم میزان انتقال حرارت از دیوار با مواد تغییر فاز دهنده با ساختار لتیسی FCC. این پژوهش با کمک نرم افزار Energy Plus و Design Builder انجام پذیرفته است. نتیجه این پژوهش بیانگر این است که بهینه ترین حالت ممکن، موقع استفاده از مواد تغییر فاز دهنده با ساختار FCC می باشد و این ساختار لتیسی باعث کاهش چشمگیر میزان مصرف انرژی در سال می گردد.

چکیده English

The excessive increase in the price and amount of energy consumption in different countries and the increasing importance of preserving the environment and non-renewable energy sources have prompted researchers to provide solutions to save energy consumption in various fields by explaining new methods. One of the things that has attracted the attention of researchers these days is the use of phase change materials in the field of construction materials. This is despite the fact that there has not been extensive research in this field in Iran. In this project, we intend to investigate the effect of using these materials on the heat transfer rate of a wall in four different conditions for one year.The first state is the rate of heat transfer from the wall without phase change materials, the second state is the rate of heat transfer from the wall with phase change materials, the third state is the rate of heat transfer from the wall with phase change materials with BCC lattice structure and the fourth state is the rate of heat transfer from the wall with FCC lattice structure phase change materials. This research was done with the help of Energy Plus and Design Builder software. The result of this research indicates that the most optimal possible mode is when using phase change materials with FCC structure and this lattice structure causes a significant reduction in energy consumption per year.
