알루미늄 창호의 구성요소에 따른 단열성능 예측

Abstract

Purpose of this study is proposal of estimating method about window thermal performance that based on KS F 2278 'Test method of thermal resistance for windows and doors' due to material composition of aluminum frame window. First step of this study is research of present state about material composition of aluminum frame window. Second is selection of main effective elements about window thermal resistance. For example, composition of Glazing, Frame area ratio of total window area, frame width, opening type, area of heat transfer and so on. Third is multiple regression analysis about thermal performance of aluminum frame window due to main effective elements. It produces equations of multiple regression analysis due to opening type. Case of sliding window is Y=0.312+0.365Xg-0.429Xfar-0.659Xfw, 4track sliding is Y=0.027+1.196Xg-0.298Xfar+0.73Xfw, Lift & Sliding Window is Y=0.204+0.285Xg+0.025Xfar-0.333Xfw, Tilt & Turn window is Y=0.073+0.757Xg-0.216Xfar-0.073Xfw
