摘要

本文通过实验研究和数值模拟相结合的手段，研究了辐射供冷系统启动阶段辐射板表面温度变化及系统稳定阶段人体散湿的强度和人员散湿的位置对结露特性的影响，结果表明：在系统启动阶段单独运行辐射供冷系统6 min后就会发生结露现象，所以在系统启动阶段要及时采取有效的预除湿措施，在此过程中，辐射板表面温度的降低比人体散湿强度的变化对结露的时间的影响更显著；在系统稳定阶段，每增加一个成年男子轻度劳动时的散湿量，结露提前12 min左右发生，人体所在位置的辐射板比其他位置处辐射板先发生结露，在防止结露时，应重点监测人体上方区域的辐射板的表面温度。

Abstract

A combined method of experimental and numerical simulation was used in this paper to study the surface temperature variations of radiant panel in the start-up stage of radiant ceiling system

and the condensation characteristics of radiant panels were analyzed under different moisture strengths and locations of human being in the stable stage of radiant ceiling system. The results show that in the start-up stage when the radiant cooling system is operated independently

the condensation occurs on the radiant panel after the system starts 6 minutes

and the decreasing of radiant panel surface temperature has more significant impact on the condensation time than the increasing of moisture strength. So it is necessary to take effective measures to prevent condensation in time in the start-up stage. In the stable stage

the radiant panel condenses about 12 minutes earlier when the moisture strength equivalent to an adult man body is additionally added. And the radiant panel which is exactly above the moisture source condenses earlier than others. So the surface temperatures of radiant panels above the moisture source should be monitored to prevent condensation.
