PNEUMATIC SOLAR COLLECTOR USING POROUS CERAMICS SPHERICAL LAYER AS HEAT COLLECTION VENT LAYER

摘要

PROBLEM TO BE SOLVED: To develop a solar collector with high heat collection efficiency by improving a year operation rate and increasing the amount of feed air. SOLUTION: A pneumatic solar collector is provided, in which a plurality of inclined layers of plate shaped vent layers each comprising a porous ceramics spherical layer with a particle diameter of about 1 to 10 mm that forms in the collector a solar light heat absorption/storage surface such that it passes through the surface while shielding a flow of air, and further air and the porous ceramic spherical structure are heat exchanged with the aid of the flow of the air when the air passes through the porous ceramics spherical layer and with the aid of a circulation flow between adjacent plate shaped vent layers.
