Abstract

The aim of the present study is to clarify the thermal performance of the radiant cooling system with Water Flow on Roof, which employs the evaporative cooling effect on the roof surface. In this paper, the thermal performance of this system is discussed from a point of view of the coefficient of performance, using a test house. Measurement results reveal that the indoor globe temperature of the test room is kept below 28 °C on summer days when the maximum outside temperature exceeds 30 °C. The COP varied from 0.9 to 5, in the experiment periods.

屋顶水流辐射冷却系统的研究
本研究的目的是阐明利用屋顶表面蒸发冷却效应的屋顶水流辐射冷却系统的热工性能。本文利用试验室,从性能系数的角度对该系统的热性能进行了讨论。测量结果表明,在室外最高温度超过30℃的夏季,试验室室内温度保持在28℃以下。在试验期内,COP变化范围为0.9 ~ 5。
