| Abstract |
This study aims to present fundamental data for improving the performance of window system. The evaluation of thermal performance was conducted with various assembly of window components.
Analysis of heat transfer was performed through the use of simulation programs(WINDOW, FRAME and FRAMEplus) for sliding-type and fixed-type windows prevalently applied to residential and commercial buildings. With the simulation, the U value of window system was estimated according to the variation of frame materials, spacer type, backing seal element and window size.
The results were as follows: First, the U value of the centre-glazing in pair-glasses was shown with different values by the gases, but the values were increased again over the 13㎜ of the width. Secondly, thermal performance of window system was presented by the thermal conductivity of frame with the simulation of 24㎜ clear and low-e pair-glasses. Thirdly, with the analysis of the U value of window system by spacer and backup seal type, thermal edge can be applyed to decrease the condensation at the edge of glazing by increasing thermal resistance rather than improve the U value of window system. |
