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(專業(yè)版)
【正文】 其中，代表性截面X=。四個環(huán)境因素包括空氣溫度、相對濕度、室內(nèi)維護(hù)結(jié)構(gòu)內(nèi)表面平均溫度以及氣流速度，兩個人體因素為人體能量代謝率和人體服裝熱阻。關(guān)鍵詞：氣流組織 熱舒適 室內(nèi)空氣品質(zhì) CFD 數(shù)值模擬Numerical Simulation of the Influence of Air Distribution on Indoor Air Environment QualityCivil Engineering College of Hunan University Jiao Junjun Gong Guangcai Shao ChunshengAbstract: The air distribution is the final link of the indoor air environment including the thermal and humidity 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 in
