엘리베이터 조닝 계획(수직 구획)에 따른 고층 건물에서의 동절기 압력분포 특성 분석

This paper deals with the effect of elevator vertical zoning on pressure distribution caused by stack effect in high-rise buildings where the heights of passenger elevator shafts are the key parameter that affects the magnitude and distribution of stack pressure. First, survey was made to know the present status of elevator vertical zoning plan in high-rise residential buildings. As a result of the survey, two zone type that compart whole building into upper floors and lower floors was most common type and there were several cases according to the numbers and methods of vertical zoning. Next, using the CONTAMW, airflow simulations were performed to understand characteristics of pressure distribution of such cases: single zone type, two zone type one, and multi zone type elevator zoning. Sky lobby elevator system used in super high-rise buildings over 70th floors was also evaluated to investigate the potential problems.
