摘　　要：为改善应用辐射板供暖系统的办公室内热环境,以哈尔滨某办公室为研究对象,利用Airpak软件对办公室应用九种辐射板加新风系统方案进行数值模拟,分析了不同方案下办公室室内温度、预测平均评价(PMV)以及空气龄等指标的分布,利用层次分析法建立室内气流组织的评价体系,对冬季工况下各方案的气流组织进行综合评价,结果表明,采用地面辐射供暖加置换送风、墙面辐射供暖加置换送风两种方案时的室内气流组织优于其他方案。In order to improve the thermal environment of office applying radiant heating system, an office in harbin applying nine radiant heating combining with fresh air system are respectively simulated by the CFD software Airpak. According the numer-ical simulation result,we analyzed different indoor temperature distribution,PMF,age of air,etc. Indoor air distribution evaluation system is established to evaluate nine radiant heating combining with fresh air system in the winter condition. The result shows that radiant floor heating combining with replacement air supply, wall surface radiant heating combining with replacement air supply are more superior than other projects.
