Title:
冬季太陽光の熱吸収作用を呈する採光装置
Document Type and Number:
Japanese Patent JP7114848
Kind Code:
B2
Abstract:
To attain improvement/enhancement of a life environment in winter, namely, to attain new effective utilization of sunlight in winter at a low elevation angle by supporting processing such as heating, snow melting and dew condensation prevention through an action of transferring heat which is generated on a heat absorption surface of a tabular member for daylighting to a peripheral area, etc.SOLUTION: In a daylighting device, a plurality of tabular members 2 is disposed in a parallel state, the tabular member including a sunlight reflection portion on a mirror surface 2a and a sunlight heat absorption portion on a heat absorption surface 2b on a rear side. For each of the tabular members 2, a side of the heat absorption surface 2b presenting a heat absorption action is set downward and southward, and a side of the mirror surface 2a presenting a reflection action is set upward and northward. The entire tabular member 2 is disposed in a southward and upward tilted mode that sunlight in winter at a low elevation angle reaches the heat absorption portion. Sunlight 5 in southing about at the winter solstice is absorbed by the heat absorption surface 2b, sunlight 6 in southing about at the spring equinox and the autumn equinox and sunlight 7 in southing about at the summer solstice are incident indoors.SELECTED DRAWING: Figure 1
