摘　　要：进行了以风冷热泵作为冷源,毛细管地板辐射供冷,毛细管顶板辐射供冷和风机盘管供冷的实验研究,分析了三者在热泵启停机后室内温度场的变化,比较了三者的启动时间长短和蓄冷能力的大小。实验数据表明,风机盘管系统启动时间最短,但蓄冷能力最差,停机后室内温度变化迅速,热舒适性差。地板辐射启动时间最长。但是,地板辐射蓄能能力强,能够在停机后继续供冷,有效节约能源。此外,辐射供冷相比与风机盘管具有室内水平温度分布均匀,竖向温差小,舒适性强的优点。Radiant floor cooling,radiant ceiling panel cooling and fan-coil unit's cooling experiments were respectively conducted by air-cooled heat pump.As for the three terminal systems,difference indoor temperature in the three systems after starting and stopping the heat pump was analyzed,the start-up time and energy storage capacity among the three terminal devices were described.The experimental date showed that radiant floor cooling had the longest start-up time,but it had the biggest energy storage capacity,so that it can maintain to offer cooling during the following hours.But also horizontal temperature field distributed evenly,the temperature vertical gradient is very small in the systems of both radiant floor and ceiling panel cooling.
