ABSTRACT:
A solar heating device which indicates the proper window covering status for maximum energy conservation. A support structure (18) rests on window sill (16) and suspends two thermistors (22 and 24). One thermistor (22) is supported on the room side of drapery (12) and the other thermistor (24) is supported between drapery (12) and a window (14). When the net heat flow is inward from outside the room, thermistor (24) near window (14) will be warmer than room side thermistor (22). When this occurs, the temperature dependent resistances of thermistors (22 and 24), voltage divider resistances (30 and 32), and a comparator (36) turn on a light emitting diode (28). This indicates that drapery (12) should be opened to let solar radiation in to heat the room. Otherwise, drapery (12) should be closed to conserve the existing heat in the room.
