Thermal comfort prediction of an underfloor air distribution system in a large indoor environment

Indoor Airflow Simulation inside Lecture Room: A CFD Approach

“…Therefore, a Computational Fluid Dynamics (CFD) study is necessary in order to investigate the air flow pattern and air flow distribution, which will help to identify the locations where air distribution is inadequate. This has been supported by previous studies (Lim et.al [1], Lim et.al [2], Cheong et.al [3], Ruponen & Thinker [4] and Gon et.al [5]). 1 To whom any correspondence should be addressed.…”

Prediction of thermal comfort, IAQ, and energy consumption in a dense occupancy environment with the under floor air distribution system

“…Kim et al [15] numerically concluded that the UFAD system is capable of creating a more comfortable environment than the MV system in a large indoor environment. Alajmi et al [16] concluded that combining field survey with physical and subjective measurements, and augmenting them with CFD analysis, provides capable methodology for examining the thermal comfort conditions of a building that is served by an UFAD system.…”

Thermal comfort in the Fraschini theatre (Pavia, Italy): Correlation between data from questionnaires, measurements, and mathematical model

“…In particular [1] is focused on CO 2 dispersion in auditorium, while in [2] thermal comfort conditions in Galatsi Arena in Athens were analyzed. Finally Kim et al [3] present an analysis on whether the application of a underfloor air distribution system for a large cultural facility space could result in higher satisfaction level for indoor thermal comfort. Other papers consider thermal comfort models studies in climate conditions similar to the ones of the present work, also focusing on other kind of buildings [4][5][6].…”

“…Furthermore no openings are in general present in this kind of structures, so that only mechanical ventilation is possible. Many studies [1][2][3] are focused on thermal comfort, air quality and air distribution in large environments, but they are not specifically related to theatres. In particular [1] is focused on CO 2 dispersion in auditorium, while in [2] thermal comfort conditions in Galatsi Arena in Athens were analyzed.…”
