To use glazing systems protected by automatic sprinklers as fire barriers in building compartmentation, fire endurance tests of these systems have been performed by several research workers. Most of the tests concerned the types of glasses and sprinklers, sprinkler water flow rate, and sprinkler activation time. Horizontal side wall sprinklers and window glazing systems with a vertical center mullion were mainly applied in the tests. In the study, full-scale fire endurance tests were carried out to verify the ability of large glazing systems divided by a horizontal mullion and protected by pendent vertical sprinklers. The result shows that the protrusive length of the horizontal mullion, which is perpendicular to the glass surface, is the main parameter that determines the fire resistance rating of the systems. The mullion obstructs the water flow in the glass.

본 연구는 최근 고층 건축물의 외장 마감으로 사용되는 커튼월 중, 유니트 커튼월 방식의 양중 문제 해결을 위하여 커튼월의 수직부재인 멀리온을 레일로 활용하고자 하였다. 커튼월 멀리온의 레일 적용에 따른 양중 가능 여부는 Mock-Up Test의 진행을 통해 20m/sec의 풍속에도 양중이 가능한 것으로 나타났으며, 비교를 위해 선정된 현장 기준으로 공사 기간은 약 20% 단축이 가능하며 투입 인원은 약 33%를 줄일 수 있을 것으로 분석되었으며, 10,000㎡의 설치를 가정하면 80% 이상의 시공비용 절감이 가능한 공법으로 판단된다.

Today, many kind of buildings are higher than those of previous generations, and Curtain Wall is adapted broadly as an outer wall material. But weather and environmental condition could cause problems in curtain wall construction in most construction projects. High wind speed and unplanned lifting equipment's allocation could cause construction delay and cost increase. To solve these problems, we suggest using a curtain wall mullion as a rail to lift curtain wall which is less affected wind speed. And we would like to show a preliminary data of its economic advantage evaluation.

The objective of this article is to present an analysis of all heat transfer paths through the energy nose under closed door conditions when refrigeration system of household refrigerator-freezer is operating on. Both experimental and numerical methods are suggested as a means of determining the overall energy nose load amount as well as the load due to each pathway such as mullion section and F and R sides of the household refrigerator-freezer. In other words, all loads determined in this article are just energy nose and not the loads seen by the refrigeration system. We suggest good ideas for improving the heat transfer losses such as conduction and convection through the energy nose. As we can be known from the experimental test results, it is effective to prevent the heat loss of a mullion section. And energy efficiency is also decreased approximately 6% compared to that of a baseline sample test result. As we can be known from the Ansys 8.1 analysis, it is shown the steady state temperature distribution in figures from 6 to 8. And the direction of the heat flow through the energy nose section is also easily seen from that In conclusion, the article is focused on an energy nose section in household refrigerator-freezer for practical proposes which is the energy saving in a household refrigerator-freezer. And the method suggested may be applied to any make or model to aid in the search for high efficient energy nose section of household side by side refrigerator-freezer as well as top mounted refrigerator-freezer, commercial refrigerator and so on.

본 연구는 냉장고의 냉장실과 냉동실 사이에 있는 멀리언부의 가스켓 주위의 열전달 해석을 수행하여 이 부분에서 열손실을 크게 하는 구조물인 구조보강용 철구조물 유무에 따른 전산해석을 통한 열전달 해석과 이의 결과에 대한 검증을 위해 냉장고 내부 벽면의 온도를 측정하여 열손실 분석을 통한 냉장고 열손실을 개선하는 것을 목적으로 하였다. 본 연구를 통해 철구조물이 있는 경우에 이를 통하여 고온의 Hotline과 외부 공기의 열이 잘 전달되어서 냉장고의 열손실에 크게 영향을 미치는 것을 알 수 있었으며 이를 제거하면 냉장고 열손실이 24.8% 감소하여 철구조물을 제거하는 것이 냉장고 열손실 설계 개선을 크게 향상시킴을 알 수 있었다.

The purpose of this study is to survey the transition of the type of openings in korean traditional archiectures. To do this, various types of openings at the backside of Daechung of 23 Hyang-Gyo Myung-Ryun-Dangs were investigated. After the classification in some groups according to their types and their periods of constuction, the tasnsition of the type of openings was analysed. Results are as follows. (1) The openings constructed form 16th to 17th century, the earliest form, is a ledged and battened panel window(or framed and ledged panel window) whose mullion is built on the frame of window. It is presumed that these types were widely used before 17th century. (2) The next type is ledged and battened panel window(door) (or framed and ledged panel window) which lacks a mullion. These types were thought to be customed after 18th century. (3) The lastest type, which is appeared from 19th to 20th century, is an characteristic backside opening(ledged and battened panel window or framed and ledged panel window) that among 3 column spacings the central one is enlarged in comparison with the right and left ones. Through this transition pattern of the openings, can be menifested that the trend of 20th century is to enlarge convenience of usage by constuctiong door and eliminating some windows.

본 논문은 1990년대 ~ 2011년 시공중인 건축물의 커튼월의 단열성을 평가하기 위하여 내외 표면 온도를 측정하여 부위별 온도 차이를 분석하였다. 유리면이나 단열층이 있는 표면보다 커튼월의 프레임 (멀리온 바 및 스팬드럴 바)의 온도는 동절기 외부평면의 경우 6℃~10℃ 정도 높게 나타났다. 또한, 같은 프레임에서도 앵커유닛이 있는 부위가 다른 프레임보다 2℃~3℃ 더 높게 나타나 보다 큰 열 손실이 일어나고 있는 것으로 나타났다.

This study mainly inquired characteristics and changes of 'Chang-aelgool' through 38 cases(with 161 Ssang-chang) of annex and pavillion buildings in Yeong-nam region which are built during the Chosun dynasty. The method of inquiry included actual survey of windows along with bibliographical research, and the results are as below. First, through the discovery of the term 'Chang-aelgool' as an indication of the window-forming frame in 'YeongGeonUiGwe'(1680 A.D), it is apparent that the term 'Chang-aelgool' was widely used in Korea from the late 17th century. Second, the 'Chang-aelgool' of study objects are classified into 4 categories. Type I and II are comprised of mitre-joints which cover the 4 corners of 'Chang-aelgool' and mainly used in building annex and pavillion buildings during the early period of the Chosun dynasty. Type III was widely used during the early and middle period of the Chosun dynasty and drastically dropped in number during the late period of the dynasty. Type IV is comprised of mitre-joint of the upper-half, tenon-jointing of the lower-half and widely used in annex and pavillion building during the late period of the Chosun dynasty. Third, the form of 'Chang-aelgool' has changed from rectangular form with longer width during the early period of Chosun dynasty to square form during the middle period and eventually ended up as a rectangular form with longer height during the late period of the dynasty. Fourth, it is considered that while mullion which is located in the center of 'Chang-aelgool' was mainly used around the main floored room during the early period of the Chosun dynasty, became commonly used in main floored room and 'ondol' rooms during the middle period and drastically dropped in number from then and ended up being not in use after the mid 18th century.
