The present invention relates generally to ventilation systems and, more particularly, to ventilation systems for reducing pathogen transmission.
The emergence of respiratory diseases, such as the severe acute respiratory syndrome (SARS) epidemic in 2003, the H1N1 influenza epidemic in 2011, and the current COVID-19 pandemic, highlights the importance of controlling the spread of pathogens exhaled by persons within buildings, particularly healthcare facilities. Unfortunately, conventional ventilation systems in healthcare facilities can exacerbate the spread of pathogens from patients within those facilities.

The illustrated air supply partition 20 has a housing 22 that is rectangular-shaped with opposite first and second faces 22a, 22b, and opposite first and second sides 22c, 22d. In some embodiments, the housing 22 has a height of between about sixty inches (60″) and seventy two inches (72″), and a width of between about forty eight inches (48″) and eighty four inches (84″). However, an air supply partition 20 according to embodiments of the present invention is not limited to a rectangular shape or to these dimensions. The air supply partition 20 may have various shapes/configurations, as well as various other dimensions.
The housing 22 has an internal chamber 24, a plurality of air inlet apertures 26 in the second side 22d that are in fluid communication with the internal chamber 24, and a plurality of air outlet apertures 28 in the first face 22a that are in fluid communication with the internal chamber 24. At least one filter 30, such as a HEPA filter, is positioned within or otherwise in communication with the internal chamber 24. The air supply partition 20 includes at least one fan 32 that is configured to cause air to be drawn in through the air inlet apertures 26, through the at least one filter 30, and out through the air outlet apertures 28 into the area A. In some embodiments, a vertical array of fans 32 are utilized. Each fan 32 may be a variable speed fan driven by an electronically commutated motor (ECM), for example. However, various types of fans/motors may be utilized.
The illustrated air exhaust partition 40 has a housing 42 that is rectangular-shaped with opposite first and second faces 42a, 42b, and opposite first and second sides 42c, 42d. In some embodiments, the housing 42 has a height of between about sixty inches (60″) and seventy two inches (72″), and a width of between about forty eight inches (48″) and eighty four inches (84″). However, an air exhaust partition 40 according to embodiments of the present invention is not limited to a rectangular shape or to these dimensions. The air exhaust partition 40 may have various shapes/configurations, as well as various other dimensions.
The housing 42 has an internal chamber 44, a plurality of air inlet apertures 46 in the first face 42a that are in fluid communication with the internal chamber 44, and a plurality of air outlet apertures 48 in the second side 42d that are in fluid communication with the internal chamber 44. At least one filter 50 is positioned within or otherwise in communication with the internal chamber 44. The air exhaust partition 40 includes at least one fan 52 that is configured to cause air from the area A to be drawn in through the air inlet apertures 46 in the first face 42a, through the at least one filter 50, and out through the air outlet apertures 48 in the second side 42d of the housing 42. In some embodiments, a vertical array of fans 52 are utilized. Each fan 52 may be a variable speed fan driven by an ECM motor. However, various types of fans/motors may be utilized.
In operation, air is drawn in through the second side 22d of the air supply partition 20 via air inlet apertures 26, filtered, and then forced out through the first face 22a of the partition and across the area A. The air supply partition 20 utilizes directional displacement to help dilute and move airborne contaminants towards the air exhaust partition 40 in order to mitigate the spread of pathogens from persons within the area A. Air is drawn in through the first face 42a of the air exhaust partition 40, filtered, and exhausted harmlessly within the interior space through the air outlet apertures 48 in the second side 42d of the air exhaust partition 40. This configuration of the air supply partition 20 and the air exhaust partition 40 creates the push-pull airflow across the area A which helps remove pathogens within the area A.
In some embodiments, the air exhaust partition 40 includes at least one UV light source 54 that is configured to irradiate air flowing through the air exhaust partition housing with UV radiation. UV radiation can be effective in substantially reducing various contaminants and pathogens, including bacteria and viruses.
In some embodiments, an air supply partition can be configured to cause air to be supplied into two adjacent areas. For example, air outlet apertures can be formed in both the first and second faces 22a, 22b of the air supply partition housing 22 illustrated in
