摘　　要：通过Airpark建立模型并将测试得到我国南方夏季使用新风空调系统(DOAS)结合吊顶辐射(CRCP)制冷工况下室内外的温湿度变化,墙体表面的温度变化以及新风口的温度湿度,风速的平均值作为CFD模型的边界条件。研究发现室外平均气温在32.7℃时,新风入口速度为0.5 m/s,温度为20.2℃和吊顶辐射温度为21℃时室内水平面的温差小于0.8℃,竖直方向的温差不大于3℃。室内工作区域的平均空气年龄为700 s,室内的热舒适的范围在-0.4≤PMV≤0.8。结论表明DOAS&CRCP在我国南方地区夏季制冷能达到良好的热舒适性。Test recorded indoor temperature and humidity variation by using Dedicated Outdoor Air System （DOAS） and Ceiling Radiant Cooling Panels （CRCP）, in the south of China. All of parameters, included fresh-air inlet velocity 0.5 m/s, temperature 20.2 ℃, wall surface temperature, mean value were used as boundary condition in Airpak model. The study shows that each horizontal surface temperature variation was less than 0.8 ℃ and vertical surface less 3℃. From the Airpark, indicated that near the fresh-air inlet the mean age of air less than 700 s and the PMV from -0.4 to 0.8. The conclusion shows that DOAS ＆ CRCP should get a good heat comfort in south of China.
