Abstract:
1. A photocatalytic device, comprising: a housing configured to be positioned at an intake of an indoor unit of a mini-split system, the indoor unit having an intake vent; a first catalyst substrate positioned at an intake area of the housing; a second catalyst substrate positioned at an exhaust area of the housing; the first and second catalyst substrates configured to support a hydroxyl radical reaction with ultraviolet light and water vapor that results in hydro peroxides and hydroxyl ions; an ultraviolet light source located within the housing and positioned between the first and second catalyst substrate; a deflection shield portion of the housing, the deflection shield portion having a shape configured to divert airflow exiting the exhaust area of the housing into the intake vent of the indoor unit, the shape including a first portion parallel to the intake vent, a second portion perpendicular to the intake vent, and a curved portion coupling the first and second portions; a plurality of convex reflectors located within the housing, positioned to face convex surfaces of the reflectors toward one another.
