Alternatively, as shown in
The electrodes 26 may consist of a high voltage wire having a first end and a second end. The first end of the high voltage wire may contain a plurality of bristles or clusters that extend upwardly from the printed circuit board 42. The bristles are composed of any material that conducts electricity. The bristles or clusters may be composed of nylon, carbon fibers, or a thermoplastic polymer imbedded with conductive material that allows the polymer to conduct electricity. For example, the bristles may be composed of polypropylene or polyethylene and impregnated with carbon. Generally, the bristles of the electrode 26 may contain between about 20 to about 80 wt % polypropylene copolymer or polyethylene copolymer, between about 5 to about 40 wt % talc, and from about 5 to 40 wt % carbon black. However, any other resistive, inductive, reactive or conductive plastic or non-metallic material may be utilized for the bristles. As illustrated in
The device 10 may produce approximately equal amounts of positive and negative ions, regardless of airflow velocity or other conditions such as humidity or temperature. In example forms, the device 10 produces positive ions and negative ions in a concentration of at least about 40 million ions per cubic centimeter as measured 2 inches from the device electrodes. In alternate embodiments, the device generates negative ions only, or positive ions only, or generate negative ions and positive ions in unequal quantities.
In one embodiment, the top portion 20 of the device 10 may contain an LED bore that extends through the top portion 20 and into the cavity 22. An LED light may be positioned over the LED bore and engaged to an LED wire that extends from a circuit board to the LED light. When current is flowing through the high voltage wires current also flows through the LED wire and illuminates the LED light, indicating the device 10 is operating. The top portion 20 contains a first power supply bore and a second power supply bore for receiving the positive and negative power supply wires that serve as the power supply source.
The device 10 may be positioned and secured in place within the housing of the air handler unit such that the electrodes are aligned generally perpendicularly to the direction of the airflow across the device 10, to prevent recombination of the positively charged ions with the negatively charged ions.
The treatment of air by delivery of bipolar ionization to an airflow within a conduit according to the systems and methods of the present invention may be utilized for various purposes. For example, application of bipolar ionization to an airflow within an HVAC conduit such as an air handler housing or duct may be utilized to abate allergens, pathogens, odors, gases, volatile organic compounds, bacteria, virus, mold, dander, fungus, dust mites, animal and smoke odors, and/or static electricity in a treated air space to which the airflow is directed. Ionization of air in living and working spaces may reduce building related illness and improve indoor air quality; and additionally can reduce the quantity of outside air needed to be mixed with the treated indoor air, reducing heating and cooling costs by enabling a greater degree of air recirculation.
As shown in
In one embodiment, the female portion of the power head 70 is internally threaded for the receiving the externally threaded conductive device 34 in a selectively secured arrangement. Selectively secured means the two devices, or in this instance power head 70 and device 10, can be separated from each other.
The electrodes 26 within the ionizer may be removable or replaceable. The emitter points may be constructed of conductive resins, gold, titanium, or any other corrosion resistant conductive material.
