  • PHOTOCATALYTIC OXIDATION CENTRIFUGAL FAN
    Publication number: 20240033396
    Abstract: A centrifugal fan for a heating, ventilation, air conditioning, and refrigeration (HVACR) system is disclosed. The centrifugal fan includes a volute housing having an inner surface and a curved inlet shroud. The volute housing defines an air outlet. The curved inlet shroud defines an air inlet. The air inlet has an inlet airflow cross-sectional area that lies substantially perpendicular to an outlet airflow cross-sectional area of the air outlet. The centrifugal fan also includes an impeller mounted for rotation about a rotational axis within the volute housing. The impeller has a plurality of fan blades. The plurality of fan blades has an outer surface. The centrifugal fan further includes a light source. The inner surface of the volute housing and the outer surface of the plurality of fan blades includes a photocatalyst layer. The light source is configured to emit light on the photocatalyst layer.
