A Measuring Apparatus for Heat Transfer Components at the Sunlit Window with Shading Devices.

本研究的目的是探讨各种遮阳装置的遮阳效果。本文介绍了一种测量传热元件的装置，该装置包括：（1）窗模型（窗玻璃和遮光装置用平面加热器代替，加热器内产生吸收的太阳热）; ii）风洞，其中竖直壁设置有窗户模型（隧道的内部空间对应于室外。在窗户处流向室外的热量由隧道中的风控制。及iii）控制及测量仪器。使用该装置，在不向系统提供太阳辐射的情况下，我们可以在假设的室外天气条件下进行室内实验。误差检验表明，该装置实现了5%以内的测量精度，并给出了一个室外实验的实例。从窗口表面的热图像来看，再现性令人满意。

The purpose of this study is to examine the sun control effects of various shading devices attached to the inside of the window. We have constructed an apparatus for the measurement of heat transfer components and presented its outline.The apparatus consists of 1) a window model (The window glass and the shading devices are replaced by plane heaters which generate the absorbed solar heat in them.) ,ii) a wind tunnel in which an upright wall is provided with the window model (The inside space of the tunnel corresponds to the outdoors. Heat flow to the outdoors at the window is controlled by the wind in the tunnel.) , and iii) controlling and measuring instruments. Using this apparatus, without providing the system with solar radiation we can conduct an indoor experiment under hypothetical outdoor weather conditions. Examinations of the errors prove that the apparatus realizes the measurement within accuracy of 5%.Furthermore, we have reproduced an example of an outdoor experiment using the apparatus. Judging from the thermal images at the window surface, the reproduction is satisfactory.
