چکیده
در این پژوهش، مواد تغییر فازدهنده (PCM) به عنوان ابزاری نوین جهت کنترل درجه حرارت در سیستم‌های حرارتی، مورد بررسی و ارزیابی قرار گرفته‌اند. این مواد، به صورت هوشمند و بدون نیاز به تجهیزات مکانیکی، اقدام به تغییر فاز می‌نمایند و با تطابق طبیعی با نوسانات محیط، به بهبود کنترل حرارت و بهبود مصرف انرژی در سیستم‌های حرارتی می‌پردازند. این تحقیق به بررسی و طبقه‌بندی خصوصیات این مواد می‌پردازد و کاربردهای آن‌ها در اجزای مختلف ساختمانی اعم از دیواره‌ها، پنجره‌ها، آجر، سنگ مصنوعی، سقف و کف ساختمان مورد بحث و بررسی قرار می‌دهد. نتایج به دست آمده از استفاده این مواد نشانگر این است که می‌توان آن‌ها را به عنوان یک راهکار نوین برای بهینه‌سازی مصرف انرژی در ساختمان‌ها به کار برد. برای مثال، استفاده از PCM در دیواره‌ها منجر به کاهش مصرف انرژی گرمایی می‌شود و به کمک نانوعایق در شیشه پنجره‌ها، نیاز به سیستم‌های گرمایش و سرمایش کاهش یافته و از آنجا کاربران مستقل از نیاز به این امکانات می‌شوند. همچنین، اثر PCM در سنگ‌ها به پایداری حرارتی افزوده و در آجرها اثرات گلخانه‌ای را به‌طور قابل توجهی کاهش می‌دهد. به طور کلی، استفاده از PCM در کف ساختمان باعث افزایش ظرفیت ذخیره‌سازی حرارتی می‌شود. این نتایج نشان‌دهنده امکانات کاربردی واحد PCM به عنوان یک راهکار اثربخش در بهبود کارایی انرژی ساختمان‌ها است.
