Contaminant scrubber of a heating, ventilation, and air conditioning (HVAC) system
A contaminant scrubber of a heating, ventilation, and air conditioning (HVAC) system includes a sorption cavity, a sorption inlet damper configured to receive return air from a conditioned space and into the sorption cavity, and a sorption outlet damper configured to output the return air from the sorption cavity and toward the conditioned space. The contaminant scrubber also includes an outer housing about the sorption cavity, the outer housing having a mount-facing side wall along which the sorption inlet damper and the sorption outlet damper are disposed.
1. A contaminant scrubber of a heating, ventilation, and air conditioning (HVAC) system, the contaminant scrubber comprising:
a sorption cavity;
a sorption inlet damper configured to receive return air from a conditioned space and into the sorption cavity;
a sorption outlet damper configured to output the return air from the sorption cavity and toward the conditioned space;
an outer housing about the sorption cavity, the outer housing including a mount-facing side wall along which the sorption inlet damper and the sorption outlet damper are disposed;
inner cabinetry disposed within the outer housing;
a first inner space of the sorption cavity; and
a second inner space of the sorption cavity separated from the first inner space by the inner cabinetry, wherein the sorption inlet damper extends into the first inner space, and wherein the sorption outlet damper extends into the second inner space.
2. The contaminant scrubber of claim 1 , comprising:
an additional side wall of the outer housing that is adjacent and coupled to the mount-facing side wall; and
a purge and regeneration inlet damper disposed along the additional side wall and configured to direct outdoor airflow into the sorption cavity.
3. The contaminant scrubber of claim 2 , comprising a door assembly forming a portion of the outer housing, disposed along the additional side wall, and configured to provide access to the sorption cavity.
4. The contaminant scrubber of claim 2 , comprising:
a second additional side wall of the outer housing that opposes the additional side wall and is adjacent and coupled to the mount-facing side wall; and
a purge and regeneration outlet damper disposed along the second additional side wall.
5. The contaminant scrubber of claim 2 , comprising a rain hood disposed on an outer surface of the additional side wall and over the purge and regeneration inlet damper, wherein the rain hood is configured to block ingress of liquid through the purge and regeneration inlet damper.
6. The contaminant scrubber of claim 1 , comprising a purge and regeneration inlet damper having a rectangular flow path perimeter.
7. The contaminant scrubber of claim 1 , comprising a door assembly configured to provide access to the sorption cavity and having a door panel, an insulating layer, and an additional door panel, wherein the insulating layer is positioned between the door panel and the additional door panel.
8. The contaminant scrubber of claim 1 , comprising:
a door assembly at least partially defining the outer housing, configured to provide access to the sorption cavity, and having a door panel; and
a gasket strip disposed between the door panel and a frame member of a frame of the outer housing.
9. The contaminant scrubber of claim 1 , comprising a contaminant cartridge set disposed within the sorption cavity and configured to decontaminate the return air received by the sorption inlet damper.
10. The contaminant scrubber of claim 1 , wherein the contaminant scrubber is configured to be disposed in an outdoor environment.
11. The contaminant scrubber of claim 1 , wherein the mount-facing side wall comprises:
a mounting box; and
a frame member disposed between the mounting box and the sorption cavity.
12. The contaminant scrubber of claim 1 , wherein the mount-facing side wall comprises a frame member and a mounting box such that the mount-facing side wall is configured to support a weight of the contaminant scrubber.
13. A contaminant scrubber of a heating, ventilation, and air conditioning (HVAC) system, the contaminant scrubber comprising:
a sorption cavity;
a sorption inlet damper configured to receive return air from a conditioned space and into the sorption cavity;
a sorption outlet damper configured to output the return air from the sorption cavity and toward the conditioned space; and
an outer housing about the sorption cavity, the outer housing including a mount-facing side wall along which the sorption inlet damper and the sorption outlet damper are disposed, wherein the mount-facing side wall comprises a mounting box having the sorption inlet damper and the sorption outlet damper extending therethrough.
14. A contaminant scrubber of a heating, ventilation, and air conditioning (HVAC) system, the contaminant scrubber comprising:
a sorption cavity;
a sorption inlet damper configured to receive return air from a conditioned space and into the sorption cavity;
a sorption outlet damper configured to output the return air from the sorption cavity and toward the conditioned space;
an outer housing about the sorption cavity, the outer housing including a mount-facing side wall along which the sorption inlet damper and the sorption outlet damper are disposed; and
a purge and regeneration inlet damper; and
a low leak economizer blade disposed in the purge and regeneration inlet damper.
15. The contaminant scrubber of claim 14 , wherein the purge and regeneration inlet damper comprises a rectangular cross-section.
