摘　　要：为了研究辐射供冷装置的供冷效果,从温度梯度,室内温度变化速率,以及热流密度三个方面,对毛细管、冷却吊顶、地板辐射三种供冷装置供冷效果进行对比分析,得出以下结论:模拟室垂直方向上温度梯度低于1℃/m,符合人体热舒适性的要求。模拟室室温从30℃降到26℃时,冷却吊顶的温降速度最快。冷却吊顶的热流密度最大,毛细管次之,地板辐射最小。The cooling effect of three cooling devices on the capillary, cooling ceiling and radiant floor was made a comparative study from the temperature gradient. The change rate of indoor temperature and heat flux, as well as the conclusions could be obtained. The average of vertical temperature gradient in simulated room is equal to 1 ℃/m, which meets the requirements of human thermal comfort. When the temperature in simulation room falls from 30 ℃ to 26 ℃, the temperature drop velocity for cooling ceiling is the maximum value. There are the most heat flux value for cooling ceiling, the second one for the capillary and the least one for the radiant floor.
