초록

Purpose: Investigation about how much the convection and radiation heat transfer of internal region of window product will impact its condensation resistance performance. Also window and insulated glass vertical height were sufficient to invoke temperature stratification due to the convection, this vertical temperature gradient should be impact to window product's condensation. Method: To invoke temperature stratification in the window product, assign flow convection and radiation heat flow model to an window product. The subject of window product of this study has double sashes with about 100mm distance, which has exceeds the distance criterion of simplified heat transfer method for industrial standard and can be found very commonly from South Korea's housing. 2D thermal performance simulation method were conducted first via accordance with ISO 10077 and thermal property from this initial result applied to 3-dimensional simulation's applicable regions. Result: Beside the estimation of thermal transmittance of window product were almost identical with 2D and 3D heat transfer models, condensation resistance results are differed by heat transfer model applied to the large vertical air gap within double horizontal sliding window. Conduction-only results failed to locate weak to condensation risk on the surface that faced to indoor environment.
