摘　　要：在分析传统蒙古包室内热环境的基础上,为提高传统蒙古包室内热环境的舒适度,利用计算流体动力学模拟软件建立以毛细管网为散热末端的热水采暖系统,模拟不同敷设位置的毛细管网席对蒙古包室内热环境的影响。结果表明:在35/30℃的供/回水温度下,毛细管网席分别敷设在地面、竖向敷设高度0、0.3、0.5 m时,室内人员活动区域的平均温度均在16℃以上;室内风速小于0.1 m/s无吹风感;地面敷设时室内水平方向温度分布均匀,竖向敷设只有在0.3 m时均匀;四种敷设方式垂直方向0.1~1.1 m处的垂直温差在3℃以内,但竖向维护结构敷设时0.1 m处的温度在15℃左右,不满足规范要求。因此四种工况下蒙古包内敷设毛细管网席位置以地面敷设最优,竖向维护结构敷设时,0.3 m>0 m=0.5 m。The comfort degree of traditional Mongolian yurt indoor thermal environment can be improved based on the analysis of the traditional Mongolian yurt indoor thermal environment.A hot water heating system with capillary network as the heat dissipation end was established by computational fluid dynamics simulation to simulate the influence of different capillary network seats on the thermal environment in the Mongolian yurt room.The results show that when the capillary mat is laid on the ground and the vertical height of 0,0.3 and 0.5 m respectively,the average temperature in indoor human activity area is above 16℃at 35/30℃for the supply and return water temperature.The indoor wind speed is less than 0.1 m/s and there is no draft sensation.When the capillary mat is laid on the ground,the horizontal temperature distribution is uniform.When the capillary mat is laid vertically,the horizontal temperature distribution is uniform only at the height of 0.3 m.The temperature difference between 0.1 m and 1.1 m in the vertical direction of the four laying methods is less than 3℃,but the temperature at 0.1 m is about 15℃when the capillary mat is laid vertically,which does not meet the specification requirements.The selection of the position of capillary mat in Mongolian yurts under four working conditions can be summarized.The best choice is ground laying.When the vertical height is 0.3 m for vertical laying maintenance structure,which is better than that of 0 m and 0.5 m.
