Abstract: The present heating, ventilation and air conditioning (HVAC) air conveyance apparatus is plurality of panels adapted to be field-assembled to form the conveyance apparatus. These panels include a pair of first quadrilateral panels, each defining a right-angle flange extending from each of a pair of opposite edges and a pair of second quadrilateral panels, each defining a hemmed cleat along each of a pair of opposite edges. Each hemmed cleat is shaped and dimensioned to receive one of the first quadrilateral panel right-angle flanges to form the HVAC air conveyance apparatus. Also, HVAC unit mating flanges extending from each other edge of each of the first quadrilateral panels and/or from each other edge of each of the second quadrilateral panels, such that at least a pair of opposed peripheral HVAC unit mating flanges extend from each end of the HVAC air conveyance apparatus.

Abstract: An air conditioning system includes an air handler, an evaporator coil, a blower and a heater all within the air handler. The system further includes an air filter and a transition between the air handler and the air filter. The transition includes at least four panels that together define a perimeter and an interior of the transition. A first end of the transition is configured to be attached to the air handler. A second end of the transition is opposite the first end, and an air filter is disposed at the second end. At least one of the at least four panels includes an access door that opens to allow access into the interior of the transition. A method includes positioning the first end of the transition at a first end of the air handler, and positioning the air filter at the second end of the transition.

Abstract: A door for an air cleaner housing is disclosed. The door comprises a baseplate having a first side and a second side, a gasket attached to the first side of the baseplate, a backplate connected to the second side of the baseplate, and a front plate spaced apart from the backplate by spacers, wherein the baseplate, the backplate and the front plate are attached by a plurality of fasteners. Slots may be formed in the baseplate, and a magnet is positioned in each of the slots. The baseplate, the backplate, and the gasket dimensions may be adapted to fit within an opening in an air-cleaner housing. The magnets may be positioned to hold the door in position the housing opening. The gasket comprises a cellular urethane that seals the door to the housing to prevent air leaks.

Abstract: A hybrid full-spectrum air purification device employs a UV light source; ionization, both negative and positive or only negative ions; and, adsorbent VOC filters, zeolite, potassium permanganates, carbon, polymers, tris(hydroxymethyl)aminomethane, tromethamine, and/or the like, applied to carbon monolith structures. Room temperature bi-metallic nano-particle catalysts, such as supported noble metal based catalysts (e.g. platinum, palladium, gold, silver, etc.) with inert oxide in this case platinized tin oxide (Pt/SnOx) combined with, or without, non-noble metal oxides such as manganese dioxide (MnO2) and/or titanium dioxide (TiO2), and/or the like, may also be applied to the carbon monolith(s). The device is suitable for installation immediately above, or adjacent, a cooling coil with the air flow entering the germicidal (UV) area first, followed by the VOC catalyst filters and finally being exposed to the dual/single polarity ionization zone.

Abstract: An intelligent digital assistant device receives an indication of an installation status of a consumable component of an Indoor Air Quality (IAQ) component. The IAQ component configured to alter the quality of air entering, leaving, or circulating within a building via an HVAC system, wherein the installation status of the consumable component is determined by a component sensor coupled to the IAQ component and transmitted to the wireless user device via a wireless transmitter integrated in the IAQ component. The intelligent digital assistant device receives information regarding properties of the consumable component, wherein the properties of the consumable component are determined by the component sensor and transmitted to the intelligent digital assistant device via the wireless transmitter of the IAQ component. The intelligent digital assistant device monitors the properties of the consumable component, and notifies a user when the consumable component requires maintenance or replacement.

Abstract: Systems and methods for controlling and monitoring Indoor Air Quality (IAQ) devices are described. In some embodiments, a system may include an IAQ component configured to alter the quality of the air entering, leaving, or circulating within a building, a sensor coupled to the IAQ component, the sensor configured to determine a status of the IAQ component, and a transmitter coupled to the sensor, the transmitter configured to transmit an indication of the status to a controller. In other embodiments, a method may include receiving, at a Heating, Ventilation, and/or Air Conditioning (HVAC) thermostat, data from a sensor coupled to an IAQ component configured to alter the quality of the air entering, leaving, or circulating within a building, and determining, by the HVAC thermostat, a status of the IAQ component based upon the data.

Abstract: A photocatalytic device includes a housing with inlet and outlet openings. Hydrated multi-metallic catalyst substrate(s) disposed within the housing support a hydroxyl radical reaction with water vapor and ultraviolet light from a source in the housing, resulting in hydro peroxides and hydroxyl ions. At least one ion generator disposed in the housing provides ions. A fan disposed within the housing causes air to enter the inlet opening, circulate through the catalyst substrate(s), and exit the outlet opening, carrying the ions. A power converter disposed in the housing is operatively coupled to a power connector adapted to accept a plurality of plugs or cords. Each plug or cord is configured to plug into a corresponding conventional outlet to supply a corresponding conventional alternating current voltage at conventional cycles to the power converter for powering the ultraviolet light source, ion generator(s) and fan.

Abstract: Systems and methods for the packaging of air treatment devices are shown and described. In some embodiments, a package may be configured to store an air treatment device. For example, the air treatment device may be an air filter, cleaner, purifier, or the like. The package may include a first lateral surface configured to accommodate a proximal end of the air treatment device and a second lateral surface configured to accommodate a distal end of the air treatment device. The package may further comprise a middle surface coupled between the first and second lateral surfaces. In some cases, at least a portion of the first or second lateral surfaces may include an opaque area. Moreover, at least a portion of the middle surface may include a transparent or translucent area configured to reveal at least a portion of the air treatment device.

Abstract: A photocatalytic device has an ultraviolet light source and a plurality of photocatalytic structures, such as hydrated quad-metallic catalyst surfaces. The photocatalytic device has curved reflectors that are positioned to reflect ultraviolet light against a face of the photocatalytic structures. The curved reflectors are shaped to minimize the distance traveled by the ultraviolet light between the light source and the photocatalytic structure. The curved reflector is further shaped to direct reflected ultraviolet against the surface of the photocatalytic structure in a perpendicular direction.
