Abstract
Solar heating apparatus comprises (a) a generally horizontally elongated tank to contain liquid, (b) a generally longitudinally extending horizontally elongated container extending about the tank, the container defining glazing facing one side of the tank and a top portion of the tank, adapted to receive impingement of solar radiation, the glazing spaced from the tank, (c) and a solar radiation auxiliary reflecting panel projecting generally away from a region below the level of the lower extent of the tank and exteriorly of the container to reflect solar radiation toward and through the glazing for impingement on the tank.
Claims11
In solar heating apparatus:
- (a) a generally horizontally elongated tank to contain liquid, the tank being solar radiation absorbing,
- (b) a generally longitudinally extending horizontally elongated container extending about said tank, the container defining glazing facing one side of the tank and top portion of the tank, adapted to received impingement of solar radiation, the glazing spaced from the tank, and being insulative,
- (c) and solar radiation auxiliary reflecting panels including at least one panel projecting generally away from a region below the level of the lower extent of the tank and exteriorly of the container to reflect solar radiation toward and through said glazing for impingement on the tank, said panels being hinge supported and having alternate positions in which they have been swung to extend adjacent the glazing facing the side and top portion of the tank to block heat loss from the tank at night,
- (d) the container being polygonal in lateral upright planes, and having planar generally rectangular sections of said glazing, the panels sized in correspondence to said glazing sections to which they extend respectively adjacent, in said alternate positions.
