Abstract: The ductless air handling system draws return air from a low level and discharges conditioned supply air at a high level, thereby de-stratifying and covering a large area without the need for field-installed ductwork. The outlet is composed of a series of vertical and horizontal vanes with respective adjustable louvers and flaps as well as an integral turning vane. This outlet turns the airflow from vertical to horizontal, straightens the airflow and subsequently directs the airflow for uniform distribution throughout the space without the need for ductwork. Further, a germicidal irradiation chamber within the conduit connecting the base to the outlet can disinfect air as it is circulated by the air handler.
