Abstract
Disclosed is an air purification device having a housing for holding a photocatalytic oxidation (PCO) unit and a fan assembly. The device may also optionally include a filter compartment for holding a filter such as a HEPA filter. The air purification device is configured to provide effective purification and sanitation of air in a targeted indoor environment, and in particular in a medical environment such as a hospital.
Claims20
An air purification device, comprising:
- a frame having an air inlet and an air outlet;
- a fan assembly configured to move air into the inlet, through an airflow path within an internal compartment of the frame, and out the outlet;
- and
- a photocatalytic oxidation unit disposed at least partially within the airflow path, the photocatalytic oxidation unit having a longitudinal axis that is transverse to the airflow path, and the photocatalytic oxidation unit including
- at least one photocatalytic cell panel extending along the longitudinal axis,
- one or more ultraviolet lamps extending along the longitudinal axis and configured to emanate ultraviolet light toward the at least one photocatalytic cell panel, and
- a reflector disposed within the photocatalytic oxidation unit.

- a frame having an air inlet and an air outlet;
- a fan assembly configured to move air into the inlet, through an airflow path within an internal compartment of the frame, and out the outlet;
- and
- a photocatalytic oxidation unit disposed wherein the photocatalytic oxidation unit is disposed with the longitudinal axis substantially perpendicular to the airflow path. at least partially within the airflow path, the photocatalytic oxidation unit having a longitudinal axis that is transverse to the airflow path, and the photocatalytic oxidation unit including
- at least one photocatalytic cell panel extending along the longitudinal axis,
- first and second ultraviolet lamps extending along the longitudinal axis and configured to emanate ultraviolet light toward the at least one photocatalytic cell panel,
- a medial reflector disposed between the first and second ultraviolet lamps, wherein the medial reflector includes a base surface and an angled feature that extends from the base surface at an angle, and
- first and second photocatalytic cell panels disposed on either side of the first and second ultraviolet lamps and each extending along the longitudinal axis.
