Solar heating system

摘要

A solar heating system for a building consists of a stressed-skin roof structure which includes at least one layer formed of longitudinally extended channel-shaped beam members, wherein each beam member is generally U-shaped in cross-section and positioned with its open channel directed outwardly of the building. These beam members are placed side by side with their central bight portions lying in substantially the same plane. The open outwardly facing channels of the beams are closed to form a closed channel or air space which is heated from the sun. A heat storage bed is associated with the building and means are provided for selectively circulating air from the closed channels in the layer of beams to heat the storage bed and to return the air from the storage bed to the closed channel. The heat stored in the storage bed is selectively distributed to the interior of the building through a separate air circulating circuit.
