ABSTRACT:
A series of double pane glass panels of a standard length and width, thereby decreasing cost, are installed between a pair of parallel studs in partially upright position, with a longitudinally flanged spacer strip or strip sections attached to the inside edge of each stud for spacing the panels from a single, hollow duct-collector, or a series of connected, hollow duct-collector sections which correspond in length and width to the panels. The duct-collector acts not only as a conduit for movement of air through the device, but is also specially constructed to simultaneously transfer heat to the air. Thus, the front wall of the duct-collector is dimpled inwardly, with the outside and inside surfaces of the front wall being black and the remaining inside walls of the duct-collector sections having a bright, reflecting finish. The upper and lower ends of the duct-collector or sections are closed, with an inlet at the bottom and an outlet at the top, extending through insulation which is rearwardly of the duct-collector or sections and is held in place by a rear panel attached to the studs. Special connectors for adjacent ends of the panels and for abutting ends of the hollow duct-collector sections, when used, are also disclosed. The duct-collector sections, connectors and spacer strip sections are adapted to be sold in kit form, to further decrease the cost.
