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. Additionally, an electronic speed control circuit is provided to allow completely independent operation of each blower and fan.
