<p>A modular direct solar heat window unit comprising a vertically disposed frame having a lower window unit at the lower end thereof and a pair of upper window units positioned above the lower window unit. A ventilating window unit is provided in the upper end of the frame. The lower window unit comprises a pair of horizontally spaced and vertically disposed window members with each of the upper window units comprising a pair of window members which are disposed at an angle to the vertical. A first panel member is hingedly secured at its lower end about a horizontal axis to the frame at the lower end thereof and is movable from a closed position adjacent the lower window unit to an open position. In the closed position, the first panel member protects and insulates the lower window unit. In the open position, the reflective inner surface of the first panel member reflects the rays of the sun into the lower window unit which has a solar heat collector positioned inwardly thereof. The first panel member is adjustably positioned in various positions relative to the lower window unit. A second panel member is hingedly secured about a horizontal axis to the upper end of the frame and is movable from a closed position adjacent the upper window units to an open position. In the closed position, the second panel member protects and insulates the upper window units. The second panel member is adjustably positioned in various open positions to provide varying amounts of shade to the upper window units as required. The inner surface of the second panel member is also provided with a reflective surface to enable the second panel member to also reflect rays of the sun onto the lower window units when the second panel member is properly positioned.</p> |
