초록

일반적으로 유리온실의 거터는 빗물이나 결로를 온실 밖으로 배출시키는 역할을 하는 구조물이다. 본 논문에서는 기존 거터를 개량하여 질량을 줄이고 온실의 온도차이로 발생하는 결로를 많이 담을 수 있는 새로운 거터를 설계한다. 개발할 거터는 CATIA로 설계한 후 ANSYS 구조해석과 ADAMS/Durability를 이용하여 Hot Spot해석을 수행한 결과를 바탕으로 설계하였으며, 거터의 성능을 개선하기 위해 거터의 형상, 결로의 배수, 강도 등을 고려하였다. 그리고, 개발할 거터는 설치 방법이 쉬운 결로받이 일체형 거터이며, 기존 거터보다 질량이 약 16.9% 감소하였으며 내구성도 약 10% 상향되었다.

A gutter is generally a fixed beneath the edge of a roof to carry off rainwater, or a narrow trough that collects rainwater from the roof of a building to diverts it from the structure, typically into a drain. Reasonable designs reduce the mass of the gutters (~ 16.9%), make it faster and easier to assemble, and gives it consistent strength and integrity (about 10%). New gutter systems are presented according to the results of structural analyses performed by ANSYS and ADAMS/Durability Hot Spots. In addition, the CATIA program can improve the precision of the 3D system simulations. The design of a gutter system installations also needs to comply with the specific rainfall intensities and adequate overflow provisions needs to be provided to prevent water from sides of the roofs during heavy rainfall periods. The principle outcome of this work is a computational design tool that can be used to improve the gutter performance considering a variety of factors (gutter geometry, drainage and rainfall intensity). A good gutter design must satisfy many criteria, including durability, low cost, and ease of repair and cleaning.
