Abstract
A hot air type solar heat-collecting apparatus comprises a first transparent plate, a second transparent film located thereunder, and a corrugated metal plate mounted on the underside of a second transparent film to absorb the sunlight. The metal plate forms a first group of air passages on the upperside thereof and a second group of air passages on the underside thereof.
Claims9
A hot air type solar heat-collecting apparatus for heating a room comprising:
- a transparent plate permeable to sunlight;
- a transparent plastic film which spatially faces the plate and is permeable to sunlight passing through the plate;
- an air-sealing layer spatially facing the opposite side of the transparent film to the transparent plate;
- a heat-collecting plate disposed between the transparent film and air-sealing layer in parallel relationship therewith, contacted with the transparent film and air-sealing layer and crosswise corrugated with a large number of ridges and furrows to absorb the heat of the sunlight passing through the transparent film, the transparent plastic film being continuously supported by the heat-collecting plate, which is supported on the air-sealing layer;
- a first group of air passages being defined by one side of the corrugated heat-collecting plate and the transparent film;
- a second group of air passages being defined by the other side of said corrugated heat-collecting plate and air-sealing layer;
- means for circulating air through both groups of air passages in the lengthwise direction of the heat-collecting plate, thereby heating circulating air by the heat delivered from the heat-collecting plate, and
- said means for circulating including a blower for pulling heated air from the air passages for forwarding it into said room such that said transparent plastic film can be continuously supported by the heat-collecting plate.
The solar heat-collecting apparatus according to claim 9, wherein the crests of the ridges of the corrugated heat-collecting plate are contacted with the film, and the bottoms of the furrows of the corrugated heat-collecting plate are contacted with the air-sealing layer, thereby rendering the air passages of both groups independent of each other.
The solar heat-collecting apparatus according to claim 9, wherein the transparent plate and transparent film are flat and arranged parallel with each other.
