Solar heating system

Abstract

Abstract A solar heating system including a large number of nested thin wall cylindrical collector-convertors disposed in vertical positions and housed within an insulated housing having a window therein to allow light rays from the sun to strike the collectors at any of different angles regardless of the latitude or altitude of the sun. Ultraviolet and other shorter wave length rays are converted into heat upon striking the inner surfaces of the collectors to heat the walls thereof, and infra-red and other longer wave length rays are absorbed by coatings on the collectors to likewise heat the walls thereof. Those rays which are reflected strike the opposite collector wall surfaces to again be converted to heat. The collectors are of such length as to enable multiple reflections under practically all conditions. Air to be heated is passed lengthwise along the outer wall surfaces of the collectors to pick up the heat therefrom and is then passed to a heat storage device under certain temperature conditions where it is stored for future use. The heat storage device is constructed of stacked cement plates having labyrinth passages therein through which the heated air is passed to heat the concrete. Air for heating a building or the like is passed through other labyrinth passages within the heat storage device to absorb heat therefrom. An automatically controlled valve system controls the passage of heated air between the collector-converter housing, the heat storage device and a building structure to be heated in different manners depending upon the relative temperature conditions existing within the building, the collector-convertor unit and the heat storage device.
