ABSTRACT:
An apparatus for ductlessly distributing and circulating heated air from a gas-fired heater to heat large volumes of air in industrial facilities and the like includes an upstanding structure which defines a vertically extending chamber. Openings are provided in lower and upper portions of the structure and communicate the chamber with lower and upper strata of ambient air. A blower assembly is housed within the structure intermediate the lower and upper openings. A gas-fired heater is carried by the structure externally of the chamber. Heated air from the gas-fired heater unit discharges into the chamber at a location between the lower and upper openings and combines with air being circulated by the blower in an upwardly directed flow through the chamber. The lower and upper openings are arranged such that air from the lower strata is drawn toward the lower openings, and such that air discharging from the upper openings into the upper strata moves outwardly toward the walls of the room. The effect of this type of operation is to establish a substantially toroidal air flow circulation about the apparatus which promotes a thorough inter-mixing of air from all parts of the room and promotes temperature uniformity throughout the room.
