Abstract
System and method for emanating fragrance vapor into a region. Fragrance liquid within a receptacle exhibits a liquid phase-vapor phase interface surface when in a quiescent state. Utilizing sub-pressure generators such as fan driven systems, the pressure above the interface is lowered to promote the escape of vapor molecules for dissemination into the atmosphere. The surface area of the fragrance fluid may be increased through the use of a bubbling technique to derive an effective area permitting a larger vapor molecule escape.
