Abstract

A system for decontaminating/neutralizing breathable air and surfaces in an occupied enclosed space, i.e., hydroponic greenhouses, aircraft, rail and road vehicles, in building ducts, or rooms, includes mounting an atmospheric hydroxyl radical generator along an inside surface of an occupied space having respective air inlets and air outlets. The hydroxyl radical generator includes a polygonal housing supporting a plurality of spaced crystal-spliced UV optics medical grade pure quartz, which emit/irradiate ultraviolet in the nanometer wavelength/ultraviolet spectrum of between 100 and 400 nanometers for deactivating and neutralizing atmospheric chemicals and pathogens in breathable air and surfaces. The hydroxyl radicals contact the walls of the reaction chamber housing. The hydroxyl radicals become created and excited to react quickly with impurities including VOC, virus, bacteria and fungi, rendering them inactivated and neutral. The breathable air passes through the polygonal housing and is decontaminated and neutralized of impurities before entering the occupied enclosed space.

Description

PROACTIVE AIR/SURFACE DECONTAMINATION SYSTEM AND DEVICES

FIELD OF THE INVENTION

The present invention relates use of a harmonic bio-mimicry nonchemical photonic process that results in the export of desired atmospheric hydroxyls at precisely the same rate as nature provides (2.6 million per cubic Centimeter - NASA), to neutralize toxic chemicals and pathogens in breathable air/surfaces in stationary or moving human occupied spaces.

BACKGROUND OF THE INVENTION

Ultraviolet light (UV) delivery in the form of directing ultraviolet light on unsanitary surfaces as germicides, bactericides and viricides are disadvantageous because, upon exposure to breathable air in mass transit rail and road vehicles, as well as aircraft and related airborne vehicles, such as helicopters, seating fabrics in building interior ducts and wall surfaces and other human occupied spaces, the ultraviolet light compromises fabrics and doesn’t penetrate into crevices between, or in, passenger seats or flight deck seats, located in the flight deck, separately sealed away from the air of the passenger cabin, or in seating fabrics in mass transit rail and road vehicles, in building interior ducts and wall surfaces, in hydroponic greenhouses, in portable room-sized units and other human occupied spaces. Delivery of ultraviolet light for sanitation is limited because the ultraviolet light is only as effective as the actual line of sight of the ultraviolet waves.

DESCRIPTION OF THE PRIOR ART

Methods of producing Atmospheric Hydroxyls

In the field of physics there are, to date, only a few processes in a device that generates an atmospheric hydroxyl that purportedly are useful in removing contaminants from breathable air. In theory the NASA device produces the hydroxyl in a photo catalytic oxidation (PCO) process, by emitting an ultraviolet irradiation of 254 nanometers as it interfaces with titanium dioxide (TiC ) plating. In theory, the hydroxyl is produced only at the interface site of contact at the surface of the TiCk. The hydroxyl does not exit the airstream and does not have any downstream interaction. Minimal airflow must be maintained at approximately 120 cfm. Typical HVAC systems utilize faster air movement at approximately 2000 cfm and this would not allow for the theoretical hydroxyl to form.

OBJECTS AND SUMMARY OF THE INVENTION

This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description of the Drawings. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter.

In contrast, the present invention uses airborne hydroxyl radical molecules, which are of very small molar size and can occupy almost any given space. They can occupy dark crevices that ultraviolet line of sight cannot get access to. The present invention allows for a “Harmonic” of photonic UV frequencies to be applied within a hydroxyl producing reaction chamber. The feed stock is ambient water vapor in air which will have relative humidity, this humidity is the feed stock for the reaction chamber to produce the atmospheric hydroxyl.

This action is called “Bio-Mimicry”. The present invention process is a totally green, environmentally friendly nonchemical process that results in the export of the desired atmospheric hydroxyl at precisely the same rate as nature provides, namely, at 2.6 million per cubic centimeter. The atmospheric hydroxyl process begins by exposing ambient water vapor to special UV optics having hydroxyl activation portions made of medical grade pure quartz material. The optics are designed to emit/irradiate Ultraviolet irradiation in the nanometer wavelength/Ultraviolet spectrum of between 100 and 400 nanometers, thereby producing the hydroxyls at the aforementioned quantity of 2.6 million hydroxyls per cubic centimeter, as provided in nature. This is a novel improvement over prior art NASA PCO based technology.

Hydroxyl are groups having the radical “-OH” and are represented by the symbol -OH or HO-, which can have a negative charge or be neutral. The hydroxyl functional group includes one hydrogen atom which is covalently bonded to one oxygen atom. Hydroxyl radicals are very reactive, which react quickly to hydrocarbons, carbon monoxide molecules and other air impurities, such as volatile organic compounds, (VOC), virus, bacteria and fungi. Many closed HVAC air systems can harbor microscopic bacteria, virus (i.e., Covid-19) and fungi.

For example, aircraft and other airborne transportation vehicles, such as helicopters, seat fabrics on mass transit rail and road vehicles, in building ducts and wall surfaces, in hydroponic greenhouses, and other human occupied spaces, can harbor bacteria and virus in the separate, circulated air systems.

Also, residential rooms in dwellings or assisted living communities can harbor bacteria and virus in the separate, circulated air systems.

Therefore, the present invention is a unique and novel application method for the delivery of safe and natural hydroxyl radicals into breathable air volume containers such as agricultural hydroponic greenhouses and the agricultural plant contents therein, airline flight deck or passenger cabins, and the contents therein, seat fabrics on mass transit rail and road vehicles, in building HVAC ducts and the breathable ambient or heated or cooled airflow contents therein. To be considered as well are upholstered chair seats, benches, contact surfaces such as grab bars, handles in building wall surfaces and other human occupied spaces.

In the present invention, the atmospheric hydroxyl radicals are generated in closed multi-sided housing, preferably polygonal, having therein two or more parallel UV optics which are multi segmented with crystal, so that when enabled, the hydroxyl radicals are generated. Hydroxyls are reactive and short lived, however the closed housing reaction chamber preferably has polygonal interior walls, so that the hydroxyl radicals will bounce against the walls so as to decontaminate within the reaction chamber as well as downstream in open air areas. Breathable air is then directed through the closed housing, so that the created and excited radicals will react quickly to air and surface impurities, such as pathogens and VOC’s, rendering them neutral.

The UV optics are tubular, medical grade pure quartz. The optics are designed to emit/irradiate Ultraviolet irradiation in the nanometer wavelength/Ultraviolet spectrum of between 100 and 400 nanometers.

A multi wave 'Harmonic' is created via a multiwavelength nanometer configured optic irradiation. This configuration results in the creation of the desired atmospheric hydroxyl within the hydroxyl generator reaction chamber, which is a multi-sided reaction chamber, designed in such a way as to optimize atmospheric downstream hydroxyl production, such as for example in a polygonal-shaped housing. This multi-sided reaction chamber enables the desired atmospheric hydroxyl to be injected downstream to affect positive change. The positive change is the control/neutralization of pathogens and VOC's.

The -OH formed hydroxyl molecule is the capacitor that donates electrons to the targeted pathogen, whereupon the pathogen is therefore neutralized by the 'Electron Voltage (eV')' capacitance carried by the hydroxyl. The eV is donated at the point of contact with the pathogen.

VOC’s are neutralized through the action of Bond Dissociation Energy (BDE). The capacitance of the charged hydroxyl is sufficient so as to take out of phase (decomposition) of any airborne molecular or compound structure. In Phase VOC chemistry can be harmful, therefore out-of-phase atomic airborne structures are now neutral and cannot recombine. The exception to this rule would be the recombination of water vapor, carbon dioxide and lastly oxygen (02).

This reaction sequence is essential to all life, in that water vapor feeds all life, and carbon dioxide (CO2) is necessary/essential for plant life and oxygen (02) is essential for air breathers such as humans, other animals and forms of living organisms.

Because exposure of the UV light is problematic for human eyes, the interior of the reaction chamber is custom designed to arrest UV light escaping and to maximize atmospheric hydroxyl discharge. Refraction color can come out of the unit with the generated, activated hydroxyls, but never direct UV light.

Available hydrogen is low in our natural environment, so one must add electron rings to obtain optimal amplitude as opposed to adding hydrogen for increased hydroxyl production.

The polygonal shape of the reaction chamber enhances the total ability of the chamber to produce the desired atmospheric hydroxyl.

It is essential that the atmospheric hydroxyls be produced by the exposure of ambient water vapor within a confined refractive generator chamber housing to prevent diminution of the atmospheric hydroxyls. In contrast, SanUVox, by using outward facing reflectors but no confined generator chamber housing, causes a drastic diminution of the desired hydroxyl production.

In contrast the present invention, by using the polygon shaped reaction chamber, has categoricaily enhanced atmospheric hydroxyl production.

Because exposure of the UV light is problematic for human eyes, the interior chamber holding the reaction chamber is custom designed to arrest UV light escaping and to maximize atmospheric hydroxyl discharge. Refraction color can come out of the unit with the generated, activated hydroxyls, but never direct UV light.

However, in small environments, such as in a self-contained unit in a transit vehicle (passenger rail, passenger bus, trucking cargo shipping, etc.), or in a portable room size self-contained unit (movable with casters or wheels, or stationary mounted to a room surface, such as a wall), a fan is necessary to pull the ambient air with water vapor into the polygonal hydroxyl generator with a UV quartz optics, so that the water vapor molecules become hydroxyl radicals and thereafter are pushed by the fan out of the self-contained and/or portable unit.

For safety, an air pressure safety switch is provided, so that when air flow is not detected, this unit will be dormant. A Micro Switch shuts down all systems should the device be opened when unit is in the ON/RUN position. GREENHOUSE HYDROPONIC DEVICE AND SYSTEM

In hydroponic or other greenhouses, as in Nature, the atmospheric hydroxyls are lighter than air, so they are provided below plant growing media, such as of coconut fiber, vermiculite, etc., wherein the hydroxyls located from below flow up around the roots and growing media; being lighter than 02, the hydroxyls “drift upward”. They will not penetrate fluid or solids, so parts of the roots and media must be exposed to hydroxylated air, as opposed to being in fluid or soil. This greenhouse installation also uses a 2 x 2 lamp array and has the same options as in the large building HVAC duct installation.

The agricultural hydroxyl generating units also have communications capabilities, so that the Hydroxyl Generating Device can interface with a remotecontrol pad or mobile phone.

Anti-Vibration G-Force Mitigation Clips are installed, such as spring clips which operate in only one directional installation.

Reactor Rod Safety is paramount, for prevention of Reactor Rod displacement and breakage.

The agricultural hydroponic hydroxyl generating unit also includes custom designed noise reduction adhesive pads, and strategically placed self-adhesive sound/vibration reduction material wall insulation to mitigate sound and vibration.

Building HVAC units in general have the above features, but where the optics are provided in a two optic array of a - b options, where “A” is on, but “B” is on if A fails.

In large environments such as in large building ducts, warehouses, large hydroponic greenhouses, no fan assembly is needed because the HVAC system has its own air movement capability.

In a double optic option one optic may be on to create the hydroxyl radical and the existing HVAC fan directs the hydroxyls with the dual optic availability, should there be an abnormal intrusion of VOCs' or pathogens into the HVAC system, then the sensor would alert the hydroxyl device and the second optic would then come online in order to neutralize the threat load. AIRCRAFT DEVICE AND SYSTEM:

Atmospheric Hydroxyl radical generators can be externally fastened to and otherwise added into aircraft air conduits, which, for safety reasons, provide breathable cabin air through a flexible (typically yellow) conduit from a remote source external to the aircraft, to avoid engaging the generator at the site of the aircraft tarmac. Hydroxyl radicals (separately added to the breathable cabin air or flight deck air) are provided from the remote device and vectored into the cabin of the aircraft. The remote source may be located in a separate unit located either in the airport terminal or in a remote, movable cart, located a distance away from the aircraft. This is an improvement over the cleanup of aircraft flight deck or cabin air and cabin surfaces, which is usually done with inadequate delivery of UV light from a portable cart, which can only disinfect exposed surfaces, not the general volume of breathable air and the crevices between seats and other surfaces, as well as behind grab bars and other semi-hidden surfaces. However, for security purposes, in the present invention hydroxyl radicals are directed into the aircraft air supply conduit and then into the separate zones of air within the aircraft where for safety reasons, which include biological and chemical intrusion, the air in the flight deck is completely separate from the passenger cabin air. This may also include optionally the installation of generators of hydroxyls in flight deck or passenger cabin air circulation systems in the aircraft itself.

In the aircraft embodiment, an apparatus is provided for cleaning breathable air in an aircraft, preferably in separate flight deck and passenger compartments of the aircraft parked upon a tarmac, the apparatus including: a) a hydroxyl generator positioned at a distance away from the aircraft for generating hydroxyl radicals sufficiently excited to react quickly with impurities including VOC, viruses, bacteria and mold for rendering them inactivated, the hydroxyl generator being positioned away from the aircraft to reduce a possibility of sparks near the aircraft; b) an air supply unit adjacent to the hydroxyl generator; c) a duct from the air supply unit for delivering breathable air separately into the flight deck and passenger compartments; d) a means for injecting a stream of hydroxyls from the hydroxyl generator into the breathable air within the duct for delivery of the breathable air separately into the flight deck and passenger compartments, respectively; and e) whereby the breathable air passing through duct is cleansed of the impurities before entering the respective separate flight deck and passenger compartments.

The hydroxyl generator includes a housing having an air inlet at one end and air outlet at an opposite end thereof, wherein the housing contains a plurality of spaced crystal-spliced UV optics, the UV optics being tubular, medical grade pure quartz optics designed to emit/irradiate ultraviolet in the nanometer wavelength/ultraviolet spectrum of between 100 and 400 nanometers for deactivating chemicals and pathogens in the breathable air for the respective flight deck and passenger compartments. The air inlet at one end and the air outlet at an opposite end of the housing are provided for exposing ambient water vapor to the plurality of spaced crystal-spliced UV optics, to generate the hydroxyls. Preferably, the housing comprises a lengthwise extending hollow housing having a polygon shape in cross section, with adjoining lengthwise extending flat walls.

The aircraft is connected by a passenger walkway corridor to a passenger terminal, which may include the air supply unit and hydroxyl generator, which are positioned adjacent each other within the passenger terminal.

The aforementioned duct, being hollow and preferably flexible, is located outside of the passenger walkway between the terminal and the aircraft.

Alternatively, the air supply unit and hydroxyl generator may be located on a movable cart at a distance away from the aircraft,

The duct preferably includes at a distal end adjacent to the aircraft an air flow divider separating the breathable air from the duct separately into the flight deck compartment and into the passenger compartment.

The present invention also provides a method for cleaning breathable air in an aircraft interior, preferably in separate flight deck and passenger compartments of the aircraft, comprising the steps of: i) parking the aircraft parked on a tarmac; ii) positioning a hydroxyl generator at a distance away from the aircraft for generating hydroxyl radicals sufficiently excited to react quickly with impurities including VOC, viruses, bacteria and mold for rendering them inactivated, the hydroxyl generator being positioned away from the aircraft to reduce a possibility of sparks near the aircraft; iii) placing an air supply unit adjacent the hydroxyl generator; iv) connecting a duct from the air supply unit to the aircraft for delivering breathable air separately into the flight deck and passenger compartments; v) injecting a stream of hydroxyls from the hydroxyl generator into the breathable air within the duct for delivery of the breathable air separately into the flight deck and the passenger compartments; vi) separating the breathable air into a divider for separately delivering the breathable air into the flight deck and passenger compartments; and, vii) whereby the breathable air passing through duct is cleansed of the impurities before separately entering the flight deck and passenger compartments.

In one embodiment of this method, the air supply unit for the aircraft and the hydroxyl generator are positioned adjacent each other within the passenger terminal. In an alternate embodiment of this method the air supply unit for the aircraft and the hydroxyl generator are located on a movable cart on the tarmac, positioned remotely at a distance away from the aircraft.

BUILDING DUCT HVAC DEVICE AND SYSTEM

The building HVAC duct hydroxyl generating units also have communications capabilities, so that the Hydroxyl Generating Device can interface with a remotecontrol pad or mobile phone.

Safety features include a microswitch which will shut off from inadvertent opening if the reaction chamber device is “on” when it should be “off”. The micro switch shuts down all systems should the device be opened when the generating unit is in operational status.

Anti-Vibration G-Force Mitigation Clips are installed, such as spring clips which operate in only one directional installation. Reactor Rod Safety is paramount, for prevention of Reactor Rod displacement and breakage.

The building HVAC duct hydroxyl generating unit also includes custom designed noise reduction adhesive pads, and strategically placed self-adhesive sound/vibration reduction material wall insulation to mitigate sound and vibration.

No fan assembly is needed because the HVAC system has its own air movement capability. In a double optic option one optic may be on to create the hydroxyl radical and the existing HVAC fan directs the hydroxyls with the dual optic availability, should there be an abnormal intrusion of VOCs' or pathogens into the HVAC system, then the sensor would alert the hydroxyl device and the second optic would then come online in order to neutralize the threat load.

For safety, an air pressure safety switch is provided, so that when air flow is not detected, this unit will be dormant. A Micro Switch shuts down all systems should the device be opened when unit is in the ON/RUN position.

TRANSIT VEHICLES DEVICE AND SYSTEM

The transit vehicle unit also has a unique Internal Air Baffling System, to promote the zig zag of air movement therein, to control light and prevent unwanted UV light from escaping so that the breathable air passes through the transit vehicle unit. The unique device design does not allow for any UV light to exit the unit.

The transit vehicle units were targeted to emulate certain characteristics required within the hospital framework. Pathogen and VOC control is of paramount concern and is inherent within the design parameters of the hydroxyl generating device. Consideration was also made with regard to sound control, wherein low air flow volume of 110 cubic feet (cf) must be quieter than 30 decibels or below (Hospital Quiet).

The transit vehicle units also contain an optimal - UV light refraction tubular fan assembly, which draws in the incoming air into the hydroxyl generator chamber housing. Baffles located in the transit vehicle and duct installed hydroxyl generators allow air through the hydroxyl generator but prevent exposed UV light from escaping. The sole purpose of the baffles is to arrest any UV rays from escaping the device. Any direct line of sight to the UV source would cause a "Welders Flash" incident and may temporarily harm the eyes of the observer. This type of incident is simply not allowed and is part of the safety investigation of the validation bodies UL/CSA.

The transit vehicle units also have communications capabilities, so that the Hydroxyl Generating Device can interface with a remote-control pad or mobile phone.

Safety features include a microswitch which will shut off from inadvertent opening if the reaction chamber device is “on” when it should be “off’. The micro switch shuts down all systems should the device be opened when the generating unit is in operational status.

The transit vehicle unit also includes custom designed noise reduction adhesive pads, and strategically placed self-adhesive sound/vibration reduction material wall insulation to mitigate sound and vibration.

The transit vehicle hydroxyl generating units have the above features, but the optics may optionally be provided in a two optic array of a - b options, where “A” is on, but “B” is on if A fails.

Because the transit vehicle hydroxyl generator is a self-contained, small unit, a fan assembly is needed to send air in and out of the hydroxyl generator unit for transit vehicles. Where optionally there is provided a double optic option, one optic may be on to create the hydroxyl radical and the existing HVAC fan directs the hydroxyls with the dual optic availability, should there be an abnormal intrusion of VOCs' or pathogens into the transit vehicle hydroxyl generator, then the sensor would alert the hydroxyl device and the second optic would then come online in order to neutralize the threat load.

The hydroxyl generator includes a housing having an air inlet at one end and air outlet at an opposite end thereof, wherein the housing contains a plurality of spaced crystal-spliced UV optics, the UV optics being tubular, medical grade pure quartz optics designed to emit/irradiate ultraviolet in the nanometer wavelength/ultraviolet spectrum of between 100 and 400 nanometers for deactivating chemicals and pathogens in the breathable air for the respective flight deck and passenger compartments, on mass transit rail and road vehicles, in building ducts and other human occupied spaces. The air inlet at one end and the air outlet at an opposite end of the housing are provided for exposing ambient water vapor to the plurality of spaced crystal-spliced UV optics, to generate the hydroxyls. Preferably, the housing comprises a lengthwise extending hollow housing having a polygon shape in cross section, with adjoining lengthwise extending flat walls. PORTABLE ROOM-SIZED DEVICE AND SYSTEM

The portable room sized unit also has a unique Internal Air Baffling System, located within an exterior housing of the portable room-sized unit, but outside of the actual polygonal clamshell hydroxyl generator, to promote the zig zag of air movement therein, to control light and prevent unwanted UV light from escaping so that the breathable air passes through the portable room sized unit. The unique device design does not allow for any UV light to exit the unit.

The portable room sized units were targeted to emulate certain characteristics required within the hospital framework. Pathogen and VOC control is of paramount concern and is inherent within the design parameters of the hydroxyl generating device. Consideration was also made with regard to sound control, wherein low air flow volume of 110 cubic feet (cf) must be quieter than 30 decibels or below (Hospital Quiet).

The portable room sized units also contain an optimal - UV light refraction tubular fan assembly, which draws in the incoming air into the hydroxyl generator chamber housing. Baffles located in the portable and duct installed hydroxyl generators allow air through the hydroxyl generator but prevent exposed UV light from escaping. The sole purpose of the baffles is to arrest any UV rays from escaping the device. Any direct line of sight to the UV source would cause a "Welders Flash" incident and may temporarily harm the eyes of the observer. This type of incident is simply not allowed and is part of the safety investigation of the validation bodies UL/CSA. The portable room sized units also have communications capabilities, so that the Hydroxyl Generating Device can interface with a remote-control pad or mobile phone.

The portable room sized unit also includes custom designed noise reduction adhesive pads, and strategically placed self-adhesive sound/vibration reduction material wall insulation to mitigate sound and vibration.

Building HVAC units have the above features, but where the optics are provided in a two optic array of a - b options, where “A” is on, but “B” is on if A fails.

No fan assembly is needed in large building ducts having hydroxyl generators, because the large building duct HVAC system has its own air movement capability. However, fan assemblies are needed for portable home-sized hydroxyl generators, to pull air therein from the surrounding room and push it out into the room with purified hydroxyl filled air.

In a double optic option one optic may be on to create the hydroxyl radical and the existing HVAC fan directs the hydroxyls with the dual optic availability, should there be an abnormal intrusion of VOCs' or pathogens into the HVAC system, then the sensor would alert the hydroxyl device and the second optic would then come online in order to neutralize the threat load.

In summary the hydroxyl generator includes a housing having an air inlet at one end and air outlet at an opposite end thereof, wherein the housing contains a plurality of spaced crystal-spliced UV optics, the UV optics being tubular, medical grade pure quartz optics designed to emit/irradiate ultraviolet in the nanometer wavelength/ultraviolet spectrum of between 100 and 400 nanometers for deactivating chemicals and pathogens in the breathable air for the respective flight deck and passenger compartments, on mass transit rail and road vehicles, in building ducts and other human occupied spaces. The air inlet at one end and the air outlet at an opposite end of the housing are provided for exposing ambient water vapor to the plurality of spaced crystal-spliced UV optics, to generate the hydroxyls. Preferably, the housing comprises a lengthwise extending hollow housing having a polygon shape in cross section, with adjoining lengthwise extending flat walls.

Figure 1 shows a hydroxyl generator 1 , including a polygonal-shaped housing, including a bracket brace 14 for supporting crystal-spliced UV optics 12 and 13 within respective C-shaped spring clasps 12a and 13a, which are each respectively mounted on bracket brace 14, which are mounted parallel lengthwise to each other inside the clamshell hexagon housing, but staggered so that UV optic 12 is on a different side of the bracket 14 from the side on which UV optic 13 is located, wherein the crystal spliced UV optics 12 and 13 each have a length that runs substantially the entire length of the housing of the hydroxyl generator 1. A preferred example for the crystal-spliced UV optics 12 and 13 is the GPH457T5L/4P UV Optic 4-pin Base 18” GPH457T5 of Light Spectrum Enterprises of Southampton; these optics 12 and 13 are typically 18 inches long and are made of quartz. The tubular optics 12 and 13 are composed of pure Medical Grade quartz crystal in the portion of the optics which creates the hydroxyls. The present invention adds additional frequencies to the pure crystal optics. These tubular optics 12 and 13 generate ‘Harmonic’ bio-mimicry nonchemical process of the present invention which enables the production of desired atmospheric hydroxyls at a rate commensurate with the VOC/Bio loading in that particular space to be treated with the hydroxyls.

In contrast to the medical grade quartz tubular optics, it is noted that total glass tubes cannot be used when generating UV. The glass would simply be vaporized. Some companies use a fusion of glass and quartz crystal, which is not optimal as the glass portion creates a frequency that actually attracts contaminants. This problematic action neutralizes the desired UV action. Such a fusion lamp of glass and quartz crystal is cheaper to produce, however the poor performance of the lamp would be the end result.

Other similar Medical Grade quartz tubed UV optics can be used. The optics 12 and 13 are preferably symmetrically positioned in the housing of the hydroxyl generator 1 , as shown in Figures 3 and 4 to operate most efficiently, but where in Figure 3 the crystal spliced UV optics 12 and 13 are staggered so that UV optic 12 is on a different side of the bracket brace 14 from the side on which UV optic 13 is located. Figure 4 shows an alternate embodiment where there are two pairs of UV optics, namely 112,113 and 112a, 113a. The UV optics 112, 113 are staggered to the right on one bottom side of the horizontal bracket brace 114, but are separated by upright bracket brace 114. Likewise, UV optics 112a and 113a are respectively staggered to the left on the opposite top side of the horizontal bracket brace 114, also separated from each other by upright bracket brace 114. Optics pairs 112, 113 and 112a, 113a are supported within pairs of respective C-shaped spring clasps 112c, 113c and 112d, 113d, which pairs of optics 112, 113 and 112a, 113a are each respectively mounted on bracket brace 114, and which pairs of optics 112, 113 and 112a, 113a are mounted parallel lengthwise to each other inside the clamshell hexagon housing 1.

The clamshell hexagon housing hydroxyl generator 1 has a clamshell configuration, including a clamshell top wall 2, upper side walls 7, 8, 9 and 10, fasteners 16a, 16b, a hinge at fastener 16a for opening the polygonal clamshell housing land a bottom clamshell portion, including a bottom wall 4 and angle- oriented walls 11 and 11a, whereby the polygon housing opens hinge 6 to expose the inside of the hydroxyl generator 1 for maintenance and/or repair. In addition, the polygon hydroxyl generator enclosure can be removed from the air duct wall 40A for such maintenance and repair. The hydroxyl generator also includes an adjacent electronic control box 20, which is attachable to the clamshell housing of the hydroxyl generator 1. Alternatively, as shown in Figures 3 and 4, the electronic control box 20 is preferably located outside of the air path, which may be a duct or other conduit. It can alternatively be attached outside of the duct. It communicates with the UV optics wirelessly. The reason for the polygon shape is that the hydroxyl generators generated by the crystal-spliced UV optics 12 and 13 are scattered upon being generated by the optics 12 and 13, but they dissipate quickly if not activated by contact with reflective non-absorbent surfaces inside the respective walls of the polygon. The purpose of the polygon shape is that when the hydroxyl radicals are generated, they are emitted radially in all directions from the UV crystal-spliced optics 12 and 13 and normally would dissipate when scattered radially from the optics. In order to permit the hydroxyl radicals to maintain their desired electron charge and ability to contact and inactivate mold, volatile organic compounds, pathogens, bacteria, virus, etc., they need to reflect and refract off of the reflective non-absorbent walls continuously, within the reaction chamber confined space. As atmospheric hydroxyls are being activated by being created and excited in back-and- forth activity, the air inside the air duct/plenum 40a will contact the activated hydroxyl radicals with the end result of the neutralization of any impurities, such as VOCs, virus, bacteria, fungi, etc., in the air and surfaces.

Furthermore, once these radicals are emitted, they can penetrate any crevices in any area, such as in hydroponic greenhouse plant media growing vessels, such as between seats of aircraft, mass transit rail and road vehicles, in building ducts and wall surfaces and other human occupied spaces, such as individual rooms with small self-contained hydroxyl generators, between the surfaces of seats and shelving, and anywhere where ultraviolet light by itself would not be capable of eradicating the undesirable VOCs, fungi, virus, bacteria, etc. In the aircraft environment, the polygon-shaped housing is strategically located within an air supply unit in an airport terminal building, or it can be located within a remote cart not located near the aircraft, on the tarmac of the airport, and preferably it may be provided in the air systems separately of an aircraft cabin, including the flight deck and the areas of the main cabin where passengers are seated. Therefore, the polygon shaped housings may also be strategically located in mass transit rail and road vehicles, in building ducts, in individual rooms, and wall surfaces and other human occupied spaces

As shown in the end view of Figure 3, the inside of the polygon housing 1 is located below the field of vision within the sealed off plenum so that the ultraviolet (UV) crystal-spliced tubular optics 12 and 13 will not be exposed to the eyes of any observers. Therefore, while the hydroxyl radicals are being generated, the UV energy which create hydroxyl generation from optics 12 and 13 are completely sealed off so that when the optics 12 and 13 are operational, the UV light emanating therefrom will not penetrate outside of the polygonal housing. Baffles, optionally located outside of the hydroxyl generators, but in the vicinity of the hydroxyl generators, prevent the UV light from exposure to persons. Additionally, fibrous filters may be provided at input and outlet areas of the housing containing the hydroxyl generator portion with the UV optics, to capture any undesirable airborne particulates, such as dirt and dust and other particles which may compromise the sensitive quartz material of the UV optics. There is no restriction regarding the active flow of the hydroxyls inside the hydroxyl generator 1 and no interference with the excitement of the hydroxyls produced by the exposure of ambient water vapor within the polygon shaped housing with the UV optics 12 and 13 irradiating light that causes the -OH radicals to form.

Figure 4 shows an alternate embodiment for a four optic version, where polygon hydroxyl generator enclosure 101, having top wall 102, side walls 107, 108, 109, 110 of an upper shell, as well as lower walls 105, 111a, 111 b of the clamshell housing. Figure 4 also shows the electronics control box 120. The respective pairs of optics 112, 112 and 113, 113, are supported within respective pairs of C-shaped spring clasps, which are each respectively mounted on bracket brace 114, which are mounted parallel lengthwise to each other inside the clamshell hexagon housing 101. Clamshell housing 101 is openable via hinge 106.

Figure 5 is a block diagram showing the network and electronics of the control box 20. Initially AC power 23 of 110 VAC is converted by converter 22 to low voltage 12 VDC, or else a low voltage battery alternatively delivers 12 VDC to a secure Key Switch 22a, to provide power to the Master Events Controller 20, which may have a microprocessor 21. The Master Events Controller 20 also receives input from sensors, such as Air Flow Sensor 25, UV Light Sensor 26, Proximity Switch 27 (detecting opening of the enclosure), Timer 30 and Voltage Monitor Sensor 31 . These sensors provide Sensor Input to the Master Events Controller 20. Power Switching in the Master Events Controller 20 sends 12V Pulse Width Modulation data to a PWM Speed Controlled Fan 34, to send air through the hydroxyl generator unit 1 or 101 , or to stop the flow of air when needed for safety and maintenance situations. The Power Switching also sends data via a Large Serve Outlet (LSO) to a Relay, which controls the Ballast 32, providing power to the Crystal UV Optics 12, which creates the needed hydroxyls within the hydroxyl generators 1 or 101. The Master Events Controller 20 also has a Communications Output, which can send data via a Controller Area Network (CAN) to a Visual Display 29 for user feedback. The Communications Output of the Master Events Controller 20 also sends digital data wirelessly as output to Status Feedback Units. The Communications Output of the Master Events Controller 20 also sends Wi-Fi/Bluetooth® Signal output to Wireless input devices 28 for Wireless user feedback during use.

Figure 5A is a diagrammatic flow chart, showing the electronic control box 20 of Figures 1 , 2 and 3, which is also equivalent to the electronic control box 120 of Figure 4. Adjacent to the hydroxyl generator 1 or 101 , which in Figures 1-3, the hydroxyl generators are attached by one or more brackets 19 to the electronic control box 20. Similarly, the electronic control box 120 is attached by brackets 119 of Figure 4.

In the diagrammatic flow chart of Figure 5A, related to the electrical block diagram of Figure 5, the control box 20 includes a microprocessor 21 for controlling the sensors and switches, which control the operation of the optics 12 and 13, or 112 and 113, of the hydroxyl generators 1 shown in Figures 1-3 and 4 respectively. There is also a power source being either a DC low-voltage battery 24, or an AC plug 23, to provide higher-voltage AC power. When the AC is used, a converter 22 can be provided to convert high-voltage AC to low-voltage DC power for operating any of the sensors and control elements within box 20. Box 25 of Figure 5A discloses the detector 25 to detect whether airflow is on, so that the optics 12 and 13 will only be on after airflow is confirmed, so that they are not on when there is no airflow. Box 26 of the diagrammatic flow chart of Figure 5A discloses the sensor 26 for detecting emitted light, and providing feedback to replace optics, including a secondary backup optic, which is also disclosed in box 26 of the flowchart of Figure 5A. Box 27 of the diagrammatic flow chart of Figure 5A discloses a detector with a proximity switch 27 detecting opening of the enclosure, and thereafter used to turn off the optics 12 and 13, to protect people from being exposed to the possible harmful UV light emitted from the optics 12 and 13. This detector with the proximity switch 27 shown in box 27 of the diagrammatic flow chart of Figure 5A also includes a limit switch, a micro switch and sensors. Box 28 of the diagrammatic flow chart of Figure 5A discloses the mobile phone application connection 28 for user feedback by wireless communication, such as Wi-Fi or Bluetooth® communications, between the operator, the control box 20 and hydroxyl generator 1 itself, together with a timer. The control box 20 also includes the LCD user feedback system 29, with a timer shown in box 29 of the diagrammatic flow chart of Figure 5A with a timer, as well as a further timer 30 shown in box 30 of the diagrammatic flow chart of Figure 5A, to provide feedback for regular maintenance. The voltage and frequency of AC main supply sensor 31 is shown in box 31 of the diagrammatic flow chart of Figure 5A, Box 32 of the diagrammatic flow chart of Figure 5A shows the voltage and frequency of the monitor of the ballast power outfit 32. Box 33 of the diagrammatic flow chart of Figure 5A discloses a fire sensor 33, which detects excess heat in the system. Box 34 of the diagrammatic flow chart of Figure 5A discloses a real time clock 34 which controls any fans providing and activating the airflow through the polygon hydroxyl generators 1.

In the mass transit vehicle applications, where a self-contained hydroxyl generator is located on the floor below a passenger seat, the primary source of power from the vehicle may be low voltage (12VDC) which can be accompanied by a DC/AC converter to convert the low voltage (12VDC) to higher 120V AC power to operate the hydroxyl generator within the mass transit vehicle.

In the alternate embodiment shown in block diagram Figure 5B, there are disclosed therein shown the following differences of block diagram Figure 5B from block diagram Figure 5, wherein in block diagram Figure 5B the following features are shown:

1 . The key switch (22a) can alternatively be positioned before the power supply (22);

2. The key switch (22a) can alternatively be a pushbutton;

3. The power supply (22) can alternatively be included in the Master Events Controller (MEC) 20;

4. The user feedback display (29) of Figure 5 is not needed in Figure 5B, because the Wi-Fi/Bluetooth® communication works with a mobile application;

5. The PWM Speed controlled fan (34) of Figure 5 is not needed, because the hydroxyl generator 1 will be located in an existing duct with moving air; and,

6. The power to the relay (not numbered) in Figure 5 can alternatively be provided by the Master Events Controller (MEC) 20 in Figure 5B.

EXAMPLES:

AGRICULTURAL HYDROPONIC GREENHOUSE EMBODIMENT

In the preferred agricultural hydroponic embodiment, as shown in Figures 6 and 6A, the hydroxyl generators can be used in greenhouses, for producing plants hydroponically, such as medicinal or other botanical plants, which are grown agriculturally inside a greenhouse. The plants are mounted in the greenhouse on troughs and tables, typically hydroponically, where the roots are held in place by media, such as coconut fibers, vermiculite, perlite, growstones, rockwool, pine shavings, rice hulls, peat moss, soil, sand or other mineral materials, so that a portion of the roots are soaked in hydroponic fluid, for irrigation and fertigation, and the upper part of the roots are exposed to air, which is brought through with hydroxyl radicals from the hydroxyl generators. For example, in Figure 6, hydroxyl generator 310 (polygonal-shaped) is positioned in the greenhouse 300 in an air duct 330.

The greenhouse has a top roof area 300a, side walls 300b and 300c, and a base ground level 300d. The greenhouse 300 is adjacent to a utility room 350, which has utility controls 320 for controlling the electronics and mechanics of the system, as well as a hydroponic fluid source 390, which provides the hydroponic fluid through a pipe conduit 360. The pipe 360 has the lower parts of the roots and the media soaking in the fluid, with an upper portion of the roots and media being exposed to air of the plants 370, which have roots 370a held in place by media 370b. The plants 370 are rooted in the pipe 360, with a stem portion of each plant 370 rising through a crevice 360a in the pipe 360, and a lower portion of the roots 370a being soaked in the hydroponic fluid for irrigation and fertigation, and an upper portion of the roots of 370a being exposed to air flowing out of the sock sleeve 340 into the pipe 360, through the crevice 360a, and in and around the pipe 360. The hydroponic fluid 370e is provided through the hydroponic fluid pipe 360. The polygonal-shaped hydroxyl generators 310 are produced in an enclosed air duct, which is preferably a fan 351 , and produces an airflow into an air duct 330, which emanates horizontally from the fan 351 , or other air source, then makes an upward 90-degree turn, through an air duct portion 330a, which then turns at 90 degrees horizontally at an upper portion of the utility room 350 through a horizontal portion 330b, within which is located the hydroxyl generator, just before a further downward air duct portion 330c emanates downward to the level of trough 334 inside 'the greenhouse, so that the air from the downward portion 330c of the air duct is then sent horizontally through a flexible sock sleeve 340, having multiple upper apertures 341 to permit the radical hydroxyl flows below and then around the hydroponic fluid pipe, and then contacting the air and plant roots 370a of the plants 370, within the media, such as the coconut fiber 370b. Optionally, an overhead mister hose 365 may be provided in case the plants are not hydroponically bred. In any case, the hydroxyls, whether they are blown or pumped through the root system and media in the greenhouse trough in the hydroponic growing system in the greenhouse, the hydroxyl radicals are exposed to the portions of the roots 370a and growing media 370b, so that they can be misted exposed therein while being irrigated and/or fertigated, either hydroponically, or alternatively within conventional soil media. In this version, the greenhouse 300 is connected to the utility room 350. The hydroxyl generators are installed in a strategic position at the top of the air duct 330b, before the hydroxylated air is sent downward through portion 330c of undulating air duct 330 spanning from utility laboratory room 350 and greenhouse 300 and then the air filled with hydroxyls is sent to the flexible sock sleeve 340, having upper apertures 341 for release of the hydroxyls to intermingle with the plant roots 370a of the hydroponically grown plants 370 located above the parallel troughs 334 of greenhouse 300. Flexible sock sleeve 340 is tapered to decrease in diameter towards its distal end, to accommodate for air pressure loss, due to decreasing air flow through the length of the flexible sock sleeve 340.

Figure 6A shows a detailed view of the hydroxyl flexible sleeve 340, with hydroxyls 302 therein and the arrows indicate the flow of the hydroxyls around the lower portion of the pipe with the fertigation and irrigation fluids for the hydroponics where the lower levels of the roots 370a are provided, but where the upper level of the roots exposed to air within the media 370b are then exposed to the hydroxyls of the plants 370. The trough 334 is shown below the flexible sock sleeve 340. The hydroxyls are introduced into air surrounding exposed roots, leaves, stems, vascular or phloem tissues of the plant.

In an alternate embodiment in a non-hydroponic system, as shown in Figure 7, a greenhouse 400 includes hydroxyl generators 410 and 411 , which are provided either adjacent to an intake fan 451 for airflow through and out the greenhouse 400 through exhaust fan 451 and/or motorized or pressurized shutter outlets 480, 481 . A trough 434 is provided for the plants and there may be a drip irrigation hose 470 with apertures for irrigation of hydroponic growing media 470c of the roots 470a of plants 470, where the hydroxyls less generated by hydroxyl generator 411 will mingle within the air exposed portions of the roots and in the media 470b of the plants 470. Optional hydroxyl generator 410 can be located at the intake fan for sending the hydroxyls through the airflow of the greenhouse 400 in areas above the plants.

The hydroxyl generators shown in Figures 1-7 will inactivate any VOCs or pathogens, such as virus, bacteria or fungi, anywhere in the air of the hydrogenic greenhouse buildings.

In addition, in the greenhouse embodiment, the hydroxyl generators are provided so that the hydroxyl radicals will flow adjacent to and through the media of the plants being farmed therein. AIRCRAFT EMBODIMENT

In the preferred aircraft embodiment, as shown in Figures 8 and 9, the hydroxyl generators 510 are remotely positioned away from the aircraft 501 on the tarmac 502, to reduce the possibility of sparks near the aircraft 501 , and the hydroxyls are delivered from a remote location near the air supply unit 520 within the airport terminal 504, as in Figure 8, through a flexible conduit tubing 540 to an input 550 or from a remotely positioned movable cart 525 on the tarmac 502 away from the aircraft 501 , through a flexible tubing conduit 545 to inlet 550 of the aircraft 501 itself, as in Figure 9.

For example, in Figure 8, hydroxyl generator 510 (polygonal-shaped) is positioned in a unit in the airport terminal 504, near the air supply unit 525 in the terminal 504.

Figure 9 shows the alternate embodiment where the hydroxyl generator 515 located in a movable cart 525 having air outlet 530, remotely positioned away from the aircraft 501 on the tarmac 502.

Figures 8 and 9 also show the walkway corridor 503 from the terminal to the airplane 501.

BUILDING DUCT HVAC EMBODIMENT

In the building duct environmental view of Figure 12, a multi-story building 600 is shown in partial cutaway cross section. Figure 12 shows a diagrammatic environmental view in partial cross section of a building having a duct 650 having a wall 651 into which is installed a radical hydroxyl generator, wherein the duct is a part of a heating, ventilation air conditioning (HVAC) unit through which breathable air with water vapor flows. Secondary air flow ducts are shown at the manifold joints with the main air duct 650.

Figure 5C, similar to the block diagram of Figure 5B, is a block diagram of the electronic controls of the hydroxyl generator used in HVAC building duct applications, or in other applications requiring the electronic controls of Figure 5C.

As also shown in Figure 12, air flow duct 650 having walls 651 , etc., where the duct 650 is connected to a HVAC unit 630, which provides respective heated, ambient, or cooled breathable air. An air purification hydroxyl producing unit 601 as in Figures 10, 10A and 10B, is provided inside of duct 650, so that water vapor in air flowing therethrough will contact with the light emanating from optics 612, 613, ’and upon contact therewith, will generate hydroxyl radicals to purify the air within building duct 650. Similarly, an air purification hydroxyl producing unit 601a as in Figure 11, with multiple pairs of optics 612, 613, 612a, 613a, etc., could be also provided inside of duct 650, so that water vapor in air flowing therethrough will contact with the light emanating from multiple pairs of optics 612, 613, 612a, 613a, etc., upon contact therewith, will also generate hydroxyl radicals to purify the air within building duct

650 of the building 600 shown in Figure 12.

Figures 10, 10A and 10B show a building duct 650 with a support wall 651 , having an HVAC unit duct hydroxyl generator 601 , similar to hydroxyl generator 1 shown in Figures 1-3 with a pair of optics 612, 613. Figure 11 shows an alternate embodiment, similar to the hydroxyl generator as in Figure 4, for a hydroxyl generator 601 A with two pairs of oppositely situated optics , attached to duct wall

651 of building duct 650 of building 600 herein. The hydroxyl generator 601 or 601a has a hinged polygonal shaped housing 603, which is openable in a hinged clamshell configuration, with a upper portion 625 of clamshell housing 603 having holes for attachment fasteners at a distal end 625a of upper portion 625, connected to a structural bracket 619 attached to front frame 640 of hydroxyl generator 601 or 601a and separated by a hinge 626 at its proximal edge from a stationary bottom portion 627 of the clamshell housing 603 of the hydroxyl generator 601 or 601a.

As further shown in Figures 10, 10A and 10B, the hydroxyl generator 601 also includes the polygonal-shaped clamshell housing 603, including a bracket brace 614 for supporting crystal-spliced UV optics 612 and 613 within respective fasteners, such as C-shaped spring clasps 612a and 613a, which are each respectively mounted on brackets 614, 615 and which are mounted parallel lengthwise to each other inside the clamshell hexagon housing, but staggered so that UV optic 612 is on a different side of brackets 614, 615 from the side on which UV optic 613 is located. The crystal spliced UV optics 612 and 613 each have a length that runs substantially the entire length of the housing of the hydroxyl generator 601 . Similar to optics 12 and 13 of Figures 1-3, a preferred example for the crystal-spliced UV optics 612 and 613 is also the GPH457T5L/4P UV Optic 4-pin Base 18” GPH457T5 of Light Spectrum Enterprises of Southampton, which optics 612 and 613 are typically 18 inches long and are made of quartz. The tubular optics 612 and 613 are also composed of pure Medical Grade quartz crystal in the portion of the optics which creates the hydroxyls. The present invention adds additional frequencies to the pure crystal optics. Similar to optics 2 and 13 of Figures 1-3, the tubular lamp optics 612 and 613 of Figure 10, 10A and 10B generate ‘Harmonic’ bio-mimicry nonchemical process of the present invention enables the production of desired atmospheric hydroxyls at a rate commensurate with the VOC/Bio loading in that particular space to be treated with the hydroxyls.

Likewise, as shown in Figure 11 , in certain power situations, instead of using a pair of oppositely positioned optics 612 and 613 upon a brace 614, in certain situations two pairs of optics 612, 612 and 613, 613 may be employed in polygonal shaped hydroxyl generator 601a of Figure 11, similar to hydroxyl generator 100 with two pairs of optics 112, 112, 113 and 113 as in Figure 4.

Other similar Medical Grade quartz tubed UV optics can be used in the building HVAC unit ducting of Figures 10 and 12. For example, the optics 612 and 613 are preferably symmetrically positioned in the housing of the hydroxyl generator 601 , as shown in Figure 10, 10A and 10B to operate most efficiently, where in Figure 10B the crystal spliced UV optics 612 and 613 are staggered so that UV optic 612 is on a different side of the bracket brace 614 from the side on which UV optic 613 is located.

In the alternate embodiment shown in Figure 11 , where there are two pairs of UV optics, namely 612, 612a and 613, 613a within hydroxyl generator 601A., the UV optics 612, 612a of polygonal hydroxyl generator 601a are similarly staggered to the right on one bottom side of the horizontal bracket brace 614a, but are separated by upright bracket brace 614a. Likewise, as also shown in Figure 11 , UV optics 613 and 613a are respectively staggered to the left on the opposite top side of the horizontal bracket brace 614a, also separated from each other by upright bracket brace 614a.

Optics pairs 612, 612a and 613, 613a of Figure 11 are supported within pairs of respective fasteners, such as C-shaped spring clasps 612c, 613c and 612d, 613d, which pairs of optics 612, 612a and 613, 613a are each respectively mounted on bracket brace 614a, and which pairs of optics 612, 612a and 6113, 613a are mounted parallel lengthwise to each other inside the hinged clamshell hexagon housing 601a.

Similar to the clamshell polygonal configurations of hydroxyl generators 1 and 100 of Figures 1-3 and 4, the clamshell hexagon housing hydroxyl generator 601 has a clamshell configuration, including a clamshell top wall 602, upper side walls 607, 608, 609 and 610, a hinge 606 for opening the polygonal clamshell housing 601 and a bottom clamshell portion, including a bottom wall 604 and angle-oriented walls 611 and 611a, whereby the polygon housing opens hinge 606 to expose the inside of the hydroxyl generator 601 for maintenance and/or repair within building duct 650.

In addition, the polygon hydroxyl generator enclosure can be removed from the air duct wall 651 for such maintenance and repair, but only when power is shut off, so that maintenance personnel are not exposed to visually harmful beams from optics 612 and 613.

Similar to hydroxyl generator 1 of Figures 1-3, the hydroxyl generator 601 also includes an adjacent electronic control box 620, which is attachable to the clamshell housing of the hydroxyl generator 601 , or provided in the vicinity thereof. Alternatively, the electronic control box 620 is preferably located outside of the air path, which may be the building HVAC unit duct or other conduit, where it can optionally be attached outside of the duct 650, wherein the control box 620 communicates with the UV optics 612, 613 wirelessly ( or to optics 612, 612a, 613, 613a of a four bulb configuration).

The reason for the lengthwise extending polygon shape of the clamshell reactor housing 601 is that the hydroxyls generated by the crystal-spliced UV optics 612 and 613 could be scattered upon being generated by the optics 612 and 613, and theoretically dissipated quickly, if not activated by constant repetitive contact with reflective non-absorbent surfaces inside the respective walls of the polygonal shaped housing of hydroxyl generator 601 or 601a.

Therefore, the purpose of the polygon shape is that when the hydroxyl radicals are generated, they are emitted radially in all directions from the UV crystal- spliced optics 612 and 613 and normally would dissipate when scattered radially from the optics 612 and 613 ( or to optics 612, 612a, 613, 613a of a four bulb configuration). But, in order to permit the hydroxyl radicals to maintain their desired electron charge and ability to contact and inactivate mold, volatile organic compounds, pathogens, bacteria, virus, etc., the hydroxyls need to reflect and refract off of the reflective non-absorbent interior walls of hydroxyl generator 601 continuously, within the reaction chamber confined space of its respective polygonal shape, which may be hexagonal, octagonal or any other polygonal shape. As atmospheric hydroxyls are being activated by being created and excited in back-and- forth activity within the polygonal shaped hydroxyl generator 601 , and upon existing therefrom, the humid molecules of air inside the air duct/plenum 651 will contact the activated hydroxyl radicals flowing out of the hydroxyl generator 601 , with the end result of the neutralization of any impurities, such as VOCs, virus, bacteria, fungi, etc., in the air and surfaces.

Furthermore, once these hydroxyl radicals are emitted to the breathable air of the human inhabited building, they can penetrate any crevices in any area of the building interior having HVAC unit duct 650, such as between seats of building interior furniture, between the surfaces of building room desks; and cabinets, or in any crevice where ultraviolet light by itself would not be capable of eradicating the undesirable VOCs, fungi, virus, bacteria, etc. The polygon-shaped housing 601 is strategically located within an air duct wall of building duct 650, which can be in a building which has sub walls extending to various rooms in the building 600.

As also shown in the end view of Figure 11 , the inside of the polygon housing 601 is located below the field of vision within the sealed off plenum so that the ultraviolet (UV) crystal-spliced tubular optics 612 and 613 will not be exposed to the eyes of any observers. Therefore, while the hydroxyl radicals are being generated, the UV energy which create hydroxyl generation from optics 612 and 613 are completely sealed off so that when the optics 612 and 13 are operational, and the UV light emanating therefrom will not penetrate outside of the polygonal housing. There is no restriction regarding the active flow of the hydroxyls inside the hydroxyl generator 601 and no interference with the excitement of the hydroxyls produced by the exposure of ambient water vapor within the polygon shaped housing of hydroxyl generator 601 , with the UV optics 612 and 613 irradiating light that causes the -OH radicals to form. During maintenance, the optics are completely turned off, so that no UV light will emanate out of the polygonal shaped hydroxyl generator 601.

Figure 11 also shows the alternate embodiment for hydroxyl generator 601a, similar to hydroxyl generator 100 of Figure 4, for a four optic version, where polygon hydroxyl generator enclosure 601a, having top wall 602, side walls 607, 608, 609, 610 of an upper shell, as well as lower walls 605, 611a, 611b of the clamshell housing 601 A. Figure 11 also shows the electronics control box 620. The respective pairs of optics 612, 612a and 613, 613a, are supported within respective pairs of fasteners, such as C-shaped spring clasps 612a and 613a, which are each respectively mounted on bracket brace 614, which are mounted parallel lengthwise to each other inside the clamshell hexagon housing 601a. Clamshell housing 601a is openable via hinge 606.

The hydroxyl generators 601 or 601a shown in the multi-story building 600 of Figure 12, provide clean air in the duct 650 in connection with the heating, ventilation air conditioning (HVAC) unit through which breathable air with water vapor flows, where the water vapor molecules generate the hydroxyl radicals for cleaning heated, ambient, or cooled air with the building 600.

The radical hydroxyl generators 601 , 601a installed in building ducts 650 of buildings 600 of Figures 10, 10A, 10B, 11 and 12 are capable of destroying 99.99% (4-Log) of biological contaminants (bacterial, fungal, and viral), ensuring a clear operation of the heated, ambient, or cooled air produced by the HVAC unit 630 of building 600 shown in Figure 12. The radical hydroxyl generating system provides all the benefits of mother-nature’s natural air purification in the atmosphere, but now located in the indoor environments, such as in building 600 that people live in.

For installation of hydroxyl generator 601 or 601a into a building duct 650, the installer must first ensure that there is adequate clearance for service. If a humidifier is present, the hydroxyl generator 601 should be installed in the airstream before the humidifier Furthermore, any plastic components should be shielded from direct UV exposure.

The installer must turn off all power to the HVAC unit 630 in the building duct 650, before installation or maintenance procedures.

Wi-Fi CONFIGURATION

Additionally, once the hydroxyl generator 601 or 601a is ready for installation, it must be set up with a Wi-Fi system 28 communicating with the control box 20 of Figures 5, 5A and 5B.

As shown in Figure 12, after properly installing the hydroxyl generator 601 or 601a into a wall 651 of the building duct 650 for the HVAC unit 630, it is plugged into a wall outlet and powered on , such as, for example by using a pushbutton (for example colored red) on a front panel. With the pushbutton pressed and the unit plugged in, the red pushbutton should illuminate. If the red pushbutton does not illuminate, it must be checked to ascertain if the unit is plugged in.

To set up the Wi-Fi network, as shown in drawing Figures 13,14,15 and 16 once the hydroxyl generator 601 or 601a is powered on and not connected to a local Wi-Fi network, a Wi-Fi hotspot will automatically be generated. To connect the hydroxyl generator 601 or 601a to a local Wi-Fi network, the installer goes to the WiFi settings on any smartphone or computer. In the list of available networks, there will be a hotspot network with a name that starts with an identifier, such as, for example, “HVAC Unit #xx”. Using a password, such as for example “utsisgreat”., the hydroxyl generator 601 or 601a is connected to the Wi-Fi network Upon connecting to the network, a Wi-Fi Manager portal with instructions (see Figure 13) will automatically open.

In the Wi-Fi Manager there will be three options: “Configure WI-FI”, “Info” and “Exit”. To continue setting up the unit to a local Wi-Fi network, the installer presses the instruction “Configure Wi-Fi”. This will open the portal page such in the screen shot image of Figure 14 This page of Figure 14 shows all the scanned networks and their associated signal strength. The installer then enters the credentials of a local Wi-Fi network into the two text input boxes at the bottom of the digital screen page labeled as “SSID” and “Password.” After inserting the Wi-Fi credentials, the installer clicks the “SAVE” button shown i8n the screenshot image of Figure 14, to finish the configuration and close the Wi-Fi Manager portal. If the input credentials are correct, the hydroxyl generator 601 or 601a will connect to the network and will turn off its hotspot. It is noted that the aforementioned Wi-Fi setup is only required during initial installation or after Wi-Fi credential change.

An indicator light, preferably yellow, is provided on the front panel of each hydroxyl generator 601 or 601a. During normal operation, this light should be off. A blinking light indicates a problem with the hydroxyl generating optics A solid light would indicate that the unit is not connected to Wi-Fi. Network 28 of Figures 5, 5A and 5B.

Figure 15 a screenshot that is used to remotely check the status of the hydroxyl generator 601 or 601a in question. In the top right corner of the page the user clicks on the “Select Device” dropdown menu of Figure 14 and select the name of the hydroxyl generator 601 or 601a being tested.

This will open a page similar to the one shown in Figure 15. This page would be populated with real-time data sent by the selected hydroxyl generator 601 or 601a with the following data displayed on the page:

Device Name:

Power Status: Green - ON; Red - Error; White - OFF

Diagnostic LED: White - No Errors; Blinking Red - Problem with Hydroxyl Bulb(s)

Runtime: Time the bulbs have been ON for. This value can be reset.

Airflow Speed: Speed of air going through unit

Figure 16 is a computer screen shot image of the operation of the Wi-Fi network of the radical hydroxyl generator of Figures 10, 11 and 12, being installed in a building duct wall 651 or building duct 650. Figure 16 also displays power status, diagnostics LED, hydroxyl generation status, run times, reset run times, air flow speed and an option to remove the device.

The following shows possible solutions for the problems the user may encounter during the operation of the hydroxyl radical generator in building ducts.

1 -Product is not turning on: Check power source and if the voltage is adequate verify if lamps connectors are attached to the lamps. Note, this last step will require device removal.

2-Product cannot connect to the app: Check your internet connection, check if you are using the latest version of the app. Install the latest version, if needed.

3- Constant replacement of lamps due to malfunctioning: Check your air system for debris. If a humidifier is present, install the device in the air stream before it. Search for defects before installing the lamps. Contact lamp supplier for more troubleshooting or further actions. 4-Smells during operation: Check for possible contact of UV light with plastic materials inside the chamber or its vicinity.

BUILDING DUCT DEVICE INSTALLATION

As shown in Figures 17-22A, in order to install the hydroxyl generator 601 or 601a in a duct 650 of a building 600 with an HVAC unit 630, s, a rectangular opening must be cut to provide access to the hydroxyl generator 601’s or 601 s’s operative chamber, namely its clamshell housing 603 with light producing optics 612, 613 arranged therein, (or to optics 612, 612a, 613, 613a of a four bulb configuration).

A duct opening cut out 652 is made within a duct wall 651 of the building duct 650 associated with the HVAC unit 630 of building 600. A first determination must be made to ensure that there is enough cross sectional volume to accommodate the clamshell housing 603 of the hydroxyl generator and its connected structural bracket 619, to fit within the building duct 650, to allow for constant air flow within the duct 650 frontal operation of the HVAC unit 630 connected to building duct 650 of building 600.

Figure 17 is a cross sectional top plan view from above of the duct 650, having a wall 651 into which the hydroxyl generator 601 or 601a is inserted through a cutout 652 of the duct wall 651 of duct 650. Figure 17A is a side view of the clamshell housing 603 of hydroxyl generator 601 or 601a installed within a building duct but showing a minimal installation depth of 12 inches into the building duct 650 of building 600.

The control box 620 of the hydroxyl generator 601 or 601a is maintained outside of the duct 650 by a front structural wall 640 that is larger than the cutout 652 of wall 651 of building duct 650 provided for insertion of the polygonal clamshell housing 603 of hydroxyl generator 601 or 601a. Fastener holes are provided within front structural wall 640 of hydroxyl generator 601 or 601a, for insertion of fasteners such as threaded bolts with reciprocating rotatable nuts, to attach front structural wall 640 of hydroxyl generator 601 or 601a to the wall 651 of building duct 650. Wall 651 of building duct 650 includes the cutout insertion hole 652 for insertion of the clamshell housing 603 therein. A structural brace 619, also located within the confines of duct 650, separates the clamshell housing 603 from the inside of front structural wall 640 of the hydroxyl generator 601 or 601a. The arrow “A” of Figure 17 indicates the direction of air flow through the clamshell housing 603 of hydroxyl generator 601 or 601a. During installation of the clamshell housing 603 of hydroxyl generator 601 or 601a, the first step is to check the air flow orientation. This is important for the operation of the hydroxyl generator 601 or 601a located within the cut out 652 of the mounting duct wall 651 of building duct 650., which follows the indications in the device (see arrow “A”) to match the hydroxyl generator 601 or 601 a’s orientation to the duct line air flow of building duct 650.

Figure 18 is a front elevation view of the hydroxyl generator 601 or 601a of Figures 12, 17 and 17A, showing a rectangular cut out 652 in a wall 651 of the building HVAC unit duct 650, showing a vertical height of the duct opening and a lengthwise width of the duct opening, wherein the arrow “A” indicates the direction of air flow with water vapor through the radical hydroxyl generator.

In a typical installation of hydroxyl generator 601 or 601a within duct wall 651 of building duct 650, the following typical dimensions required for installation:

Horizontal hole pitch: H = 4.65”

Vertical hole pitch: V = 3.75”

Rectangular opening for installation: 22” x 5.5”

Using a cutting instrument, such as a saw (or mechanical scissors) the opening 652 is cut into the wall 651 of building duct 650 , and fastener holes , such as 3/16” holes, are drilled to insert the fasteners, such as screws or nuts and bolts, to fix the hydroxyl generator 601 or 602a device in position for installation.

As shown in the exploded view of Figure 19, the hydroxyl generator 601 or 601a is placed in position so the lighting chamber with the light generating optics are completely inside the duct line and not visible from the outside of the duct 65O.The user then install the fasteners, such as crews or nuts and bolts , around the external flange of the front panel 640 of hydroxyl generator 601 or 601a Although sizes may vary, Figure 19 shows typical height of 5.5 inches and length of 22 inches of the hydroxyl generator 601 or 601 a.

OPERATION OF THE HYDROXYL RADICAL GENERATOR IN BUILDING DUCTS Switching on/off:

For use in switching on/off the USA, the voltage should be 115V AC operation voltage.

For use in other countries: the user must check local voltage before install and operation.

The user then presses the main switch to turn the hydroxyl generator on/off.

This installed hydroxyl generator 601 or 601a located within the building duct 650, can be operated remotely by using the app, after the Wi-Fi settings of the aforementioned Figures 13-16 are first configured . The user initially finds and installs the app on either the Apple or Android marketplace, then follow the steps that will guide the user through the connectivity process. For UV light optic servicing of optics 612, 613, before servicing the interior of the hydroxyl generator 601 or 601a, the user must make sure it is switched off and disconnected from power source, to avoid injuries to the eyes of the user if exposed to intense lighting from optics 612, 613, ( or to optics 612, 612a, 613, 613a of a four bulb configuration) or to exposure of the user to live electric current.

Usually, the optics 612, 613 ( or to optics 612, 612a, 613, 613a of a four bulb configuration) should be replaced after two years of operation. But this can be reduced depending on operational conditions.

To get access to the lighting chamber within the clamshell polygonal housing 603 of the hydroxyl generator 601 or 601a, the hydroxyl generator 601 or 601a must be removed from the duct line within building duct 650, by doing the reverse procedure of installation. For example, first the user must unscrew the fasteners, such as three thumb-screws at the top edge of the chamber, encompassing the clamshell housing 603, to release the hinged top portion half 625 of the structure as in Figures 20 and 20A from the fixed bottom portion 627, and then open the chamber of the clamshell housing 603 as shown opened up in Figure 20A.

As shown in Figure 20B, to replace the optics 612, 613 , the user must unplug the sockets from the optics (red and yellow cables) from the terminals. The user then reconnects the cables after replacing the optics within the clamshell housing 603 of the hydroxyl generator 601 or 601a.

For routine maintenance, the user should periodically clean the optics , using a rag with alcohol to remove the dirt that may coverthem. To clean aluminum parts, the user wipes the surface with a rag. It is strongly recommended that the user does not handle the optics without gloves, as a clean optic enhances the product performance.

Figure 21 shows an in-duct retrofit HVAC hydroxyl generator 680 installable in a duct of an HVAC unit of a building 600, wherein a plug and electrical wire are provided for connection to a power supply of the building 600 shown in Figure 12.

Figure 22 shows the front view of the retrofit hydroxyl generator 680 installed in a wall of the duct 650 in the building 600, such as building 600 of Figure 12, where the arrows “B” reflect the air flow and the orientation of retrofit hydroxyl generator in the same direction as arrow “B”.

Figure 22A is an exploded perspective view of the retrofit hydroxyl generator 680 being installed in a wall of a building duct 650 of building 600, as in Figures 21 and 22.

Designed to easily install at the manifold of the HVAC duct system the present invention enables the hydroxyl radical generator 601, 601a or 680 to disperse hydroxyl radicals throughout all areas served by the air conditioning or heating system 630 of a building duct 650 of a building 600. The installation takes only minutes, plugs in or can be hard-wired for easy connection and operates simultaneously with the air handling system in a building such as a home, building offices, industrial facilities, etc.

The hydroxyl generators for building ducts of buildings 600, shown in Figures 1-22A will inactivate any volatile organic compounds (VOCs) or pathogens, such as virus, bacteria, or fungi, anywhere in the air of the buildings and/or having the controls of Figures 5, 5A, 5B and/or 5C TRANSIT VEHICLE EMBODIMENT

Figures 23, 23A, 23B, 23C, 23D, 23E, 23F and 23G show a self-contained units 700 and 792 which can be provided within the passenger and/or cargo area 780 of a transit vehicle, which will have a smaller interior volume for producing the optimal number of hydroxyls generated to purify the air/surfaces and crevices/creases within the aforesaid areas. Such a self-contained hydroxyl generator 700 for a transit vehicle includes a generator chamber housing 701 , which is mounted inside a transit vehicle.

For example, Figure 23 shows the generator housing 701 located on the floor of the vehicle below a passenger seat where the hydroxyl generator 700 is provided in a confined space area, such as a passenger cabin with seats or a cargo container with or without shelving.

Since the transit vehicle generates low voltage 12 DC for vehicle accessories (lights, wipers, cell phone chargers, etc.), the DC power is now converted to AC by an inverter 728 to power the optics and fans of the self-contained hydroxyl generator 700.

The transit vehicle generator 700 also includes the polygon generator chamber housing 701, which has inside the optics 712, 713, which react with water vapor within incoming airflow to produce hydroxyl radicals which are excited by exposure to the interior polygonal walls of the generator 700. The transit vehicle hydroxyl generator 700 also includes an air intake 719, as well as a partition and closed compartment space 720 for the electronics, and an air blower 740 which blows and pressurizes air to the chamber of the hydroxyl generator 701. Front frame 721 is provided for controls and the air intake 719 is provided on one of the walls of the housing 701 , enclosing the clamshell shaped polygonal hydroxyl generator unit 711, which is enclosed within housing 701. The clamshell shaped polygonal hydroxyl generator unit 711 is preferably made of aluminum, or other suitable material. The clamshell shaped polygonal hydroxyl generator unit 711 has side walls 717a, 717b, top wall 717c and bottom wall 717d, as well as rear wall 717e and front cover 717f. When the aluminum cover 717c is removed, it provides easy access for optic cleaning and/or replacement of the optics of the hydroxyl generator 700, which can be taken out and opened along its clamshell hinge 716. The air is passed through the intake, blown by the blower 740, then through the polygonal generator chamber housing 701 and out through an air outlet 718. The blower 740 is mounted by a mount 741 to the exterior housing 701 of the hydroxyl generator 700.

Figure 23D shows a side view in cross-section of the hydroxyl generator 700 for transit vehicles, showing the “S- curve” diversion of the incoming and outgoing airflow “A”, which diversion is achieved by light blocking baffles 760a and 760b, where one or more staggered baffles 760a, 760b are at the air flow exit portion of the hydroxyl generator housing 701 fortransit vehicles and one or more staggered baffles 760a, 760b are at the airflow entry point of the hydroxyl generator housing 701. The staggered baffles 760a, 760b are configured to block inadvertent eye damaging light emanating from the hydroxyl generator housing, especially for curious short children or leased service dogs for people in need of canine assistance while traveling in a transit vehicle, who might tend to stare and look at the hydroxyl generator 700, located on the floor under a passenger seat of the passenger cabin 780 of a transit vehicle.

Figure 23D also shows filters 770a and 770b, which are provided at the air flow entry and exit locations within the hydroxyl generator housing 701 , to protect the optics 712, 713 etc. from contamination by airborne dirt and other particles which might accompany the incoming air flow and which may degrade the hydroxyl activation portions of the optics 712, 713, etc., which are made of sensitive medical grade pure quartz material.

The hydroxyl generators shown in Figures1-23D will inactivate any VOCs or pathogens, such as virus, bacteria or fungi, anywhere in the air of the transit vehicles 780.

Figure 23E is an exploded view of a preferred embodiment for a stand-alone hydroxyl generator 792 in a housing 791 for a transit vehicle with a three-pass air flow to limit UV light escape, where a clamshell hydroxyl generator reactor 792 with a structural cover 793 and an electronics cover 794, is insertable inside the housing 791 in the open central area shown. The air input side of the hydroxyl generator housing 791 includes a fan 795 to move air with water vapor therethrough, and a filter 796 is provided to prevent dirt, dust and other contaminating particles from compromising the sensitive quartz surfaces of the UV optics 799, 799a, which create hydroxyl radicals when water vapor from incoming air contacts the UV from the optics 799, 799a within the hydroxyl generator reactor portion 792 in an enclosure 792a having a light and air flow sensor board 798. An exit grill 797 is provided at the air exit end of the stand-alone hydroxyl generator 792, which is placed away from passenger standing or walking areas, within the confines of a transit vehicle, such as on the floor beneath one of more passenger seats in the transit vehicle.

Figure 23F is a side view in cross section of the hydroxyl generator reactor enclosure 792a, showing two UV producing optics 799, 799a and a light and airflow sensor board 798 attached thereto. Figure 23G is a diagrammatic side view in cross section of the air flow within the hydroxyl generator 792 of Fig. 23E, showing the air entry fan and the undulated “S shaped” airflow of the incoming air around the centrally located hydroxyl generator reactor, then through the hydroxyl generator reactor, and finally around the hydroxyl generator reactor in a different direction out of the stand-alone hydroxyl generator for mass transit vehicles.

PORTABLE ROOM-SIZED GENERATOR EMBODIMENT

Figures 24 to 25B show polygon hydroxyl generators 800, which are removably positioned for lower power needs in smaller confined areas, such as individual rooms in a building or schoolhouse or nursing home. Figure 24 shows a portable room sized unit 800 which can be provided, which will have a smaller interior volume for producing the optimal number of hydroxyls generated to purify the air/surfaces and crevices/creases within the aforesaid areas. Such a portable hydroxyl generator 800 includes a generator chamber housing 801 , which is mounted on a bottom wall, 819a including casters or wheels 845, 845a, 845b and 845c on the bottom for moving the hydroxyl generator 800 around in a confined space area, such as an individual room.

Figure 5D is a block diagram of the electronic controls of the hydroxyl generator used in Portable Room-Sized Unit applications, or in other applications requiring the electronic controls of Figure 5D, which include a proximity detector for safety reasons and a fan, such as a pulse width modulated fan, which regulates the air speed of the fan by regulating the voltage of the fan between on and off, to move airflow with air purifying generated hydroxyl radicals therethrough, .

Alternatively, the unit 800 can be devoid of movable wheels or casters, but can be mounted upon a wall 890( not shown).

Shown in Figure 24B, the movable generator 800 also includes the housing polygon generator chamber housing 801, which houses therein a clamshell housing having a polygonal chamber 830, which has inside the UV light emitting optics 812, 813. Baffles 820 and 820a are located inside of the portable housing 801, but outside of clamshell housing chamber 830 with optics 812, 813 to limit any leaking of UV light from the crystal-spliced tubular optics 812, 813, which upon being engaged will generate the hydroxyl radicals flowing nearby. The unit 800 also includes an air intake 840 and air exit 841 , as well as a partition and space for the electronics 820, an air blower 850 which blows and pressurizes air to the chamber of the hydroxyl generator 830. Front bezel 821 is provided for controls and the air intake 840 is provided on one of the walls 819c of the aluminum unit 801 , enclosing the housing generator 830 housing optics 812, 813 therein. The aluminum housing 801 , or other suitable material, has side walls, a top wall and bottom wall 819a, as well as a rear wall and front cover (not shown). When the aluminum cover is removed, it provides easy access for optic cleaning and/or replacement of the enclosed, sealed clamshell hydroxyl generator 830, which can be taken out and opened along its clamshell hinge 806. The air is passed through the intake, blown by the blower 850, then through the polygonal generator chamber housing 830 and out through an air outlet 841. The blower 850 is mounted by a mount 851 within the housing 801.

Figure 24B also shows a side perspective view in cross-section of the hydroxyl generator 800 for residential home use, showing the “S- curve” diversion of the incoming and outgoing airflow “A”, which diversion is achieved by light blocking baffles 860 and 860a, where one or more staggered baffles 860a are at the air flow exit portion 840 of the hydroxyl generator housing 801 for residential rooms, and also with one or more staggered baffles 860 are at the air flow entry point 840 of the hydroxyl generator housing 801. The staggered baffles 860 and 860a are configured to block inadvertent eye damaging light emanating from the optics within the polygonal optics bearing clamshell hydroxyl generator housing 830, especially for curious short children or leased service dogs for people in need of canine assistance while visiting in a residential building room, who might tend to stare and look at the hydroxyl generator 800, located on the floor of the room.

Figure 24B also shows dirt and particulate-capturing filters 890, 890a at the air intake 840 and air exit 841 of the airstream to capture any dirt or undesirable particles in the air, whether part of the air stream or adjacent air surrounding the portable room sized hydroxyl generator 800, which could compromise the quartz lamp optics 812, 813.
