Abstract

Crevices between window and window frame cause not only heat losses but also serve path to sound transmission and infiltration of fine dusts that are harmful to humans. There were many efforts in the past to eliminate these crevices but because of the windows' indispensable function of opening and closing, it was an unsolvable problem. In this study, a new type sliding window is developed by applying horizontally rolling wheels to implement a surface sealing which is excellent for enhancing air tightness. To evaluate the feasibility of the newly developed window, forces for opening and closing, durability and air tightness were testet according to Korean Testing Standards. Force for opening a 2000 N window is 30 N. It endured 100,000 cycles of opening and closing. Infiltration was $0.00m^3/(m^2h)$ for a pressure difference of 10 Pa. Since this window has few moving parts, it has favorable features of low cost and few breakdown.

창문에서의 틈은 열 손실 뿐만 아니라 차음 성능에도 중대한 결함으로 작용되며, 특히 인체에 유해한 미세먼지 유입 경로로도 작용된다. 이러한 틈을 제거하기위해 많은 시도들이 이루어지고 있으나, 창문의 고유 기능인 이동특성으로 인해 해결하기 어려운 난제로 인식되어왔다. 본 연구는 이를 해결하기위해 수평 회전 휠과 곡선 레일을 적용한 새로운 유형의 미서기 창문을 제작하고, KS 시험 기준에 따라 사용성, 내구성, 기밀성능, 등의 성능 시험을 하였다. 시험 결과, 개폐력은 2000 N 중량의 창문에서 30 N, 개폐 반복성 시험에서는 100,000 cycles, 기밀성 시험에서는 10 Pa에서 $0.00m^3/(m^2h)$의 성능을 보여주었다. 상기 시험 결과, 새로운 구동 방식을 지닌 본 연구에서의 창문은 기밀성과 경제적 측면에서 새로운 접근 방식을 제시하고 있다.
