Abstract
A fan diffuser assembly incorporates an inverted frustoconical base having a large diameter end and an opposing small diameter end. A housing is located over the frustoconical base, and has an intake end, side walls and an output end. The intake end is longitudinally spaced apart from the large diameter end of the frustoconical base and cooperates with the side walls of the housing to define an air intake of the fan diffuser assembly. An electric fan is located within the housing and is mounted adjacent the small diameter end of the frustoconical base. Operation of the electric fan generates a 360-degree laminar airflow through the air intake, along a tapering exterior of the frustoconical base, through the housing and outwardly through the output end into a surrounding environment. An air conditioning element is located inside the housing between the electric fan and the output end of the housing.
