온도차이비율과 열관류율 기준을 고려한 공동주택 삼중유리 창의 결로 방지 및 단열성능 향상 방안

The purpose of this study is to find effective ways to improve the condensation resistance and thermal insulation performance of triple glazing windows, which can satisfy the required temperature difference ratio(TDR) of the Design Standard for Preventing Condensation in Apartment Buildings and the required thermal transmittance(U-factor) of the Construction Standards for Energy-efficient Green Home. Various alternatives were selected for the tilt & turn triple glazing window directly facing to the exterior in apartment buildings. Both TDR and U-factor were calculated by using heat transfer simulations. As results, glazing and frame technologies were derived, which are effective to improve the condensation resistance and thermal insulation performance. Also, alternatives were suggested, which satisfy the required TDR and U-factor by region.
