ABSTRACT:
An energy saving heat recycling system for circulating hot air from the upper portion of a building, near the roof, to the lower portion of the building, near the floor level, to reuse the hot air to heat the lower portion of the building, such system comprising a generally cylindrical supporting sleeve, an electric fan including a fan motor mounted within the sleeve and a fan rotor to be rotated by the motor within the sleeve, means for mounting the sleeve in the upper portion of the building whereby the electric fan is to draw hot air into the intake end of the sleeve while discharging the hot air from the discharge end of the sleeve, and a flexible tubular duct connected to the discharge end of the sleeve for conveying the hot air to the lower portion of the building near the floor level, the duct being in the form of a tube made of thin flexible material which is compactly foldable for storage and shipment and is readily capable of being bent around obstructions and threaded through openings in the building. A clamping band may be employed to clamp the tubular duct around and against the discharge end of the sleeve. A thermostatic switch is preferably provided to energize the fan motor automatically, when the temperature of the air to be drawn into the fan exceeds a predetermined value.
