All season window
Patent
·
OSTI ID:6471817
An all season window includes a rectilinear peripherally extending pane mounting frame. Three panes of transparent material are secured sealingly within the frame in parallel spaced relationship and extend vertically. A solar heat ray absorbent material is contained within the frame. In one preferred form of the invention the solar heat ray absorbent material is a liquid. A pump and associated motor is provided for pumping the solar heat ray absorbent liquid between a first location in which it fills the region between the outer and intermediate panes and a second location in which the liquid fills the region between the inner and intermediate panes. In its described first location solar heat rays are absorbed by the liquid and a dead air space between the liquid and the closed environment sought to be provided with climatic control inhibits conduction of heat to such closed environment while the liquid conducts heat received thereby due to solar radiation through the outer pane to the outside environment. Such an arrangement of the solar heat ray absorbent material within the pane mounting frame is desirable during summer months. During winter months when it is desirable to minimize a loss of heat from the closed environment the solar heat ray absorbent material is moved to the region beween the inner pane and the intermediate pane.
