Title: Solar heat collector with solar cell
Inventor: ITO SADASUKE
IPC: F24J2/00
Filed: 1990-03-23
Abstract: PURPOSE:To reduce a decrease in the conversion efficiency for obtaining a hybrid type air heat collector having a relatively high heat-collecting efficiency at a low cost by providing such a construction that a solar heat collector part is located on the lower side and air flows between a top cover and a heat collecting panel. CONSTITUTION:When a heat collector receives the sunlight, a portion of the solar energy is converted into electric power by solar cells, and other portion turns to that energy and released into air in contact with a solar cell panel 1 or into a heat carrier 5 in the heat collector. A portion of sunlight radiated on a transparent part other than the solar cells is once absorbed by the solar cell panel 1 as heat energy, and the remain passes through the transparent part and received by a heat collecting panel 2. The heat energy absorbed by the solar cell panel 1 is released to the atmosphere and the heat carrier 5 in the heat collector. As the solar cell panel 1 is in contact with the atmosphere, the solar cell panel 1 is kept at a relatively low temperature. The sunlight is collected as heat energy by both surfaces of the top cover 1 and the heat collector 2, and then the heat is transferred to the heat carrier 5, resulting in a high heat collecting efficiency.
