ABSTRACT:
A spot thermal conditioning apparatus selectively operable in warming and cooling modes includes a housing containing a suction blower and a fan with radial blades. The suction blower receives ceiling air and projects an exiting stream of the ceiling air along one leg of an acute angle to an intersection. The fan is located substantially at the intersection and not only receives the exiting blower stream but also concurrently draws a stream of floor air substantially along the other leg of the angle to the intersection. The mixed air is then expelled through a louver to provide directional control of the movement of the conditioned air mass and circulation of air to an open spot work area. The suction blower and fan also each include an electronic speed control circuit so as to allow completely independent operation.
