Abstract
An improved solar collector for heating space air comprising a concentric arrangement of an inner cylindrical shell around which is coiled heat transfer tubing. Around the tubing is mounted a plurality of refractors arranged side-by-side in a plurality of directions so that as the sun moves across the sky during the day, successive groups of refractors bend the sunlight upon the coiled tubing. Air forced within the cylindrical shell is heated up by being in thermal contact with the solar heated tubing.
Claims2
A solar collector comprising, in combination:
- a plurality of refractors arranged side-by-side and facing in a plurality of directions toward that portion of the sky in which the sun appears to travel from sunrise to sunset, said refractors being disposed so that as the sun moves across the sky, successive groups of the refractors bend the rays of sunlight so that they are concentrated on a common target;
- said common target comprising tubing carrying fluid that is to be heated by the sun's rays that are concentrated and intensified by said refractors;
- said common target additionally including a cylindrical shell around which said tubing is coiled in heat-transfer contact therewith, so that the shell is heated by the hot fluid in the tubing;
- and
- means for circulating air through said shell whereby the air is warmed by contact with the heated shell and is then directed to space to be warmed.
