چکیده

مبدل حرارتی بر اساس غشاء وسیله‌ای برای بازیابی حرارت و رطوبت از هوای خروجی داخل ساختمان است. در این مقاله به منظور تشدید انتقال حرارت و جرم و کاهش افت فشار، از ساختارهای جدیدی برای غشاء این مبدل‌ها استفاده شده است. مدلسازی شامل مکانیزم انتقال حرارت و جرم برای جریان آشفته است. نتایج این پژوهش نشان می دهند، غشاء خمیده با پروفیل نیم‌ دایره باعث افزایش انتقال حرارت و جرم در حدود 7% و 6% و غشاء انحنادار باعث بهبود افت فشار تا حدود 50% نسبت به مبدل‌ حرارتی مثلثی می‌شوند.
