Abstract
A fan assembly includes a motor-driven impeller for creating an air flow, a casing including an interior passage for receiving the air flow, and a plurality of air outlets for emitting the air flow from the casing. The casing defines and extends about an opening through which air from outside the casing is drawn by the air flow emitted from the air outlets. The fan assembly also includes at least one heater for heating at least a first portion of the air flow, and means for diverting at least a second portion of the air flow away from said at least one heater. The plurality of outlets includes at least one first air outlet for emitting the relatively hot first portion of the air flow and at least one second air outlet for emitting the relatively cold second portion of the air flow.
