摘　　要：辐射供冷空调系统是一种舒适、节能的系统形式。为了比较相同面积,不同辐射面位置组合下的室内人体热舒适和能耗情况,研究以长沙某办公房间为建筑对象,采用EnergyPlus能耗分析软件对不同辐射供冷形式进行了设计日的热舒适和能耗模拟,以PMV=0为控制条件,以分体式空调系统为对照模拟,综合比较了不同辐射供冷方式下的热舒适性和能耗情况。模拟结果表明,风机盘管+顶板辐射+双壁面辐射这一组合供冷方式,在达到相同舒适条件下,节能性最优,为最佳的组合形式。Radiant cooling is a kind of comfortable and energy-saving system. In order to compare indoor human thermal comfort and energy consumption under the radiation panel at different positions,this study established a model based on an office room in Changsha,China. Thermal comfort and energy consumption model of different radiant cooling systems were built and analyzed by applying EnergyPlus. Keeping the value of PMV at zero was the control condition of energy consumption simulation. The characteristics of thermal comfort and energy consumption of different systems were compared with the split-type air conditioner. The simulation results show that the combination of fan coil,ceiling radiant cooling and two wall radiant cooling obtained the best energy saving in the same comfort conditions.
