Abstract
The invention is a disinfecting HVAC system that combines thermal displacement ventilation technology with UV-C light technology to isolate, concentrate, and/or kill harmful microorganisms (such as SARS-Cov-2) present in enclosed spaces. The system includes a single manifold collection pipe placed adjacent to the ceiling (e.g., about 12-14 feet above the floor). The collection pipe has a high collection efficiency when connected to an HVAC air handler and booster fan tandem. In the air handler, the warm air is cooled and treated with a sufficient dose of UV-C light to inactivate any microorganisms within a short amount of time. The UV-C treated air is then returned to the enclosed space through a plurality of low velocity diffusers.
Claims20
A disinfecting heating, ventilating, and cooling (HVAC) system comprising:
- a collection pipe defined by an interior passageway, a closed first end, an open second end, and a plurality of individual negative pressure nozzles that extend from a lower face of the collection pipe, wherein at least one of the nozzles has a diameter that differs from at least one other nozzle;
- an air handler in fluid connection with the second end of the collection pipe, the air handler comprising a UV-C light source, a filter, and heating/cooling coils, wherein air passing through the air handler is exposed to the UV-C light source, passes through the filter, and is heated or cooled;
- at least one fan in fluid connection with the air handler, wherein the at least one fan circulates air throughout the system;
- a plurality of low velocity diffusers positioned in fluid connection with the at least one fan, wherein the low velocity diffusers are positioned in a floor of an enclosed space and the low velocity diffusers enable airflow of about 100-400 cubic feet per minute;
- wherein the plurality of low velocity diffusers are aligned on each side of a pair of opposing walls in the enclosed space to create a plurality of air zones;
- wherein at least one nozzle is positioned within each air zone, adjacent to the ceiling of the enclosed space.
