Abstract: A spot thermal conditioning apparatus selectively operable in warming and cooling modes includes a housing containing three blowers or fans. One of the blowers receives warm ceiling air and projects an exiting stream of the ceiling air to a conditioning compartment within the housing. A fan receives the exiting ceiling air blower stream and concurrently draws a stream of cool floor air into the compartment. The mixed air is then expelled by the fan 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. An additional fan or blower is provided for circulating warm ceiling air through the housing and returning it back toward the ceiling separately from the flow of warm ceiling air moved by the other blower. The apparatus also includes a closed, heat exchange system and an air flow direction control plate.

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.
