摘　　要：为分析毛细管网不同铺设位置时室内热环境变化情况,以沈阳市某幼儿园为例,运用CFD软件AIRPAK3.0模拟了冬季幼儿园某间寝室毛细管网分别在侧墙、地板、顶棚、地板加顶棚、地板加侧墙、顶棚加侧墙时的6种铺设方式,得出室内气流组织、PMV参数分布图。结果表明:毛细管网作为末端时温度分布十分均匀,房间垂直高度温差不大。选取地板加顶棚这种铺设方式最为合适,不会出现头冷脚热的现象,人体感觉十分舒适。For the analysis of capillary network laying different position indoor thermal environment change,a kindergarten in Shenyang,for example,using CFD software AIRPAK3.0 simulated winter kindergarten dormitory capillary network respectively in the side wall,floor,ceiling,ceiling,ceiling,ceiling and side wall of six laying,it is concluded that indoor airflow organization,PMV parameter distribution.The results show that when the capillary network is the end,the temperature distribution is very uniform,and the temperature difference between the vertical height of the room is not large.Choose the floor and ceiling this laying way is the most appropriate.There will be no cold head and feet hot phenomenon,the human body feels very comfortable.
