270氣流組織對室內(nèi)空氣環(huán)境質(zhì)量影響的數(shù)值模擬(完整版)
【正文】 midity environment and the indoor air quality. By the numerical simulation method with CFD Airpak software, calculated the velocity, temperature, pollution concentration and PMVPPD distribution in the normal offices under different modes of air flow organization such as replacement ventilation and topsupplying with downexhausting air distribution, and drew some conclusions that the velocity, temperature distribution and thermal fort of replacement ventilation was superior to that of the topsupplying with downexhausting air distribution, but the pollutant control was inferior if the pollution source was at the low position. Consequently, there isn’t a unique design scheme suitable for any practical projects to obtain high indoor air environment quality, and it’s essential to consider the specific conditions in order to obtain the optimal air distribution.Key words: Air distribution, Thermal fort, Indoor air quality, CFD, Numerical simulation1. 前言室內(nèi)空氣環(huán)境包括室
