Abstract: A personal environmental module for controlling the environment in a work space, the module including a housing having an air inlet and a pair of air outlets, a pair of dampers mounted in the air inlet, one of the dampers being connected to a preconditioned air source, the other damper being connected to room air, a pair of fans mounted in the housing in a position to allow air through the dampers, a controller for controlling the speed of the fans and the amount of air flowing through the dampers and a control panel operatively connected to the controller for setting the speed of the fan and the temperature of the air discharged through the outlets. A baffle is provided in the housing to direct a portion of the air from each fan into the air flowing from the other fan in order to mix preconditioned air with the room air. An electrostatic filter and white noise generator can be mounted in the housing and a light sensor and occupant sensor operatively connected to the controller.
