JPS56151838A - Tile roof as solar heat collector - Google Patents

Abstract

PURPOSE: To obtain a large capacity solar heat collector which has high utility value by laying tiles in which water flow passages are formed on a roof and providing a water distribution tube from a ridge to eaves and a water collecting tube, thereby utilizing the roof itself as a heat collector.

CONSTITUTION: Recesses 1a, 1b are formed on a tile in which porous radiation heat absorbing members 2, 3 are contained in the recesses of a main body 1 and a transparent film 4 is adhered onto the upper surface, and drain ports 1c, 1e are arranged at the lower part of the tile. When flat tiles 5W9 are aligned on the upper surface of a roof board 10, the drain ports of the tile adjacent to the ridge side are inserted into the inlets formed at the films 4 of the respective tiles, and many flow passages connected from the ridge to the eaves are formed. The water of a water storage tank 14 is fed to a water distribution tube 12, becomes hot while flowing through the tiles on the roof, is then circulated to the tank 14. When the temperature of the water in the tank 14 is thus raised, the hot water is fed through a delivery tube 17 and is used. Thus, the solar heat can be entirely utilized, and the room is cooled in summer and is heated in winter.
