Abstract
An energy efficient, thermochromic device that may be used to allow sunlight or solar radiation into a building or structure when sunlight is absent or at high sun angles and substantially blocks solar radiation when sunlight is directly on the window.
Claims26
A window comprising at least one pane of glass or plastic, and a sunlight responsive thermochromic (SRT) device including a layer of a thermochromic material that reversibly increases in its absorption of visible and/or NIR radiation when the temperature of the thermochromic material increases and decreases in its absorption of visible and/or NIR radiation when the temperature of the thermochromic material decreases for temperatures within the active range of the system, a pair of transparent substrates, the layer of the thermochromic material being interposed between the substrates to form a laminate;
- and
- a space between the at least one pane of glass or plastic and the SRT device.
A structure comprising:
- a sunlight responsive thermochromic (SRT) device comprising a layer of a thermochromic material that reversibly increases in its absorption of visible and/or NIR radiation when the temperature of the thermochromic material increases and decreases in its absorption of visible and/or NIR radiation when the temperature of the thermochromic material decreases for temperatures within the active range of the system, and a pair of transparent substrates, the layer of the thermochromic material being interposed between the substrates to form a laminate;
- a pane of glass or plastic;
- and
- a heat mirror plastic film, wherein the heat mirror plastic film is positioned between the SRT device and the pane.
