Estimating the term…
An air purifying system includes one or more air permeable photocatalytic elements defining a core cavity having a sealed top end and an open bottom end. A sealed air flow path ensures that air travels from an outside of the core cavity, through the one or more photocatalytic elements, into the core cavity, to be expelled through the open bottom end. A UV radiation source disposed within the core cavity irradiates air travelling along the sealed flow path and an interior of the one or more photocatalytic elements. Each photocatalytic element is manufactured using a substrate, that is conductive of and transparent to UV radiation, coated with a photocatalyst. A non-photocatalytically active material is initially coated on the substrate and is then converted to a photocatalyst by calcination.
A method of manufacturing one or more photocatalytically active elements for use in a germicidal irradiation system, the one or more active elements forming a sealed flow path for passing pre-filtered air through the one or more photocatalytically active elements and thereafter through a UV-irradiated core cavity defined by the one or more elements, the core cavity having a sealed top end and an open bottom end for discharging treated air therefrom, the method of manufacturing each photocatalytically active element comprising:
