摘要
采用Airpak软件对一空调办公室内热环境进行了三维数值模拟,得到了室内流场、温度场、空气龄分布、PMV-PPD。在分析室内场分布的基础上,基于人体热舒适性指标PMV-PPD与衡量空气品质指标空气龄对室内气流组织及空气品质进行预测与评价。结果表明:基于PMV-PPD和空气龄的热环境数值预测与评价科学合理且直观形象,为相关室内热环境研究、空调系统设计及运行调节提供参考。
The thermal environment of an air-conditioned office was simulated in three-dimension by the AIRPAK software. The distribution of velocity fields, temperature fields, PMV-PPD (predicted mean vote-predicted percentage dissatisfied) and air age were obtained. Discusses the indoor field distribution then make a further prediction and evaluation of air quality and air distribution based on human thermal comfort index of PMV-PPD and measurement of air quality index of air age. It showed that the numerical prediction and evaluation of indoor thermal environment was scientific, rational and visualization based on the PMV-PPD and the air age. It provided as a reference for the relevant indoor thermal environment researches, designs and operation regulations of air-conditioned system.
