The present invention relates to air purification, and more particularly to an air conditioner with a bipolar ionization assembly. Even more particularly the present invention relates to a commercial portable air conditioner with a bipolar ionization assembly.
It is commonly known that infectious diseases, including dangerous pathogens like viruses and bacteria are communicated through both airborne means and human touch or contact. Airborne transmission spread occurs by an infected person coughing, sneezing, or vomiting, as microscopic aerosol droplets are expelled which may travel through a space where another person makes direct contact with these droplets and becomes infected. Further, in surface to person spread, an infected person may touch a surface, which another person may touch and become infected. Therefore, surfaces including work areas, desktops, tables, doorknobs, handles, keyboards, and equipment can spread these dangerous pathogens and diseases.
The commercial and industrial industries, and particularly, the healthcare and medical industries have utilized portable air conditioners for decades to provide short term cooling issues and emergency cooling applications within their facilities. These facilities include hospitals, health & rehabilitation facilities and medical labs. Portable air conditioners are used in various areas including emergency rooms, patient areas, nursing stations and other areas needing immediate climate control. Currently, such portable air conditioners do not provide adequate filtration and distribute dirty air containing, viruses, bacteria, mold spores, fungi, pet dander and a host of other dangerous particulate into the air, distributing it throughout a facility. As the healthcare and medical industries have no choice but to use portable air conditioning units in their facilities when needed, they are particularly concerned with indoor air quality (IAQ) and possible infection transmission to patients and staff. Further, it is unavoidable to breathe in contaminated air or touch various surfaces within the facilities that could possibly transmit these dangerous pathogens to healthcare workers or patients.
As can be seen, there is a need for a solution to the aforementioned problems.
Advantageously, an embodiment of the present invention provides an air conditioner with a bipolar ionization assembly which solves the aforementioned problems. In one aspect the present invention provides a commercial portable air conditioner with a bipolar ionization assembly.
In one aspect, the present invention provides an air treatment system comprising an air conditioner; a bipolar ionization assembly; and a power supply. The air conditioner may portable and include a wheeled housing; an evaporator or entry grill for ambient air; a condenser grill for hot air discharge; a cold air supply discharge grate; a motor; an evaporator coil; and an evaporator blower intake. The bipolar ionization assembly includes electrical leads, and is mounted by a bracket to the evaporator blower intake to position the electrical leads within the air stream of the evaporator blower intake. The power supply is operably connected to the portable air conditioner and to the bipolar ionization assembly. When mounted in the air conditioner, the bipolar ionization assembly creates an antimicrobial plasma capable of killing harmful pathogens including bacteria, mycoplasma, viruses, mold and odors, and reducing the presence of Volatile Organic Compounds (VOC's), particulates, and static electricity in the air.
In one aspect the commercial portable air conditioner with a bipolar ionization assembly of the present invention is capable of killing contaminants within a space on contact and is more effective than HEPA and Ultra Violet light (UV). The present invention is capable of killing viruses, mold spores, and bacteria both airborne and on surfaces, and eliminates odors at their source while providing cooling in a safe and efficient manner. The commercial portable air conditioner with a bipolar Ionization assembly and combination of cooling and sanitizing the air is safer, more effective and more efficient than any available commercial portable air conditioner on the market.
These and other features, aspects and advantages of the present invention will become better understood with reference to the following drawings, description and claims.

It is to be understood that like reference numerals refer to like parts throughout the several views of the drawings.
The following detailed description is of the best currently contemplated modes of carrying out exemplary embodiments of the invention. The description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention is best defined by the appended claims.
As used herein, “exemplary” or “illustrative” means “serving as an example, instance, or illustration.” Any implementation described herein as “exemplary” or “illustrative” is not necessarily to be construed as preferred or advantageous over other implementations. All of the implementations described below are exemplary implementations provided to enable persons skilled in the art to make or use the embodiments of the disclosure and are not intended to limit the scope of the disclosure, which is defined by the claims. For purposes of description herein, the terms “upper”, “lower”, “left”, “rear”, “right”, “front”, “vertical”, “horizontal”, and derivatives thereof shall relate to the invention as oriented in
Broadly, an embodiment of the present invention provides an air conditioner with a bipolar ionization assembly which solves the aforementioned problems. In an exemplary embodiment, an air treatment system may include a portable air conditioner with a bipolar ionization assembly, and a power supply. The commercial portable air conditioner with a bipolar ionization assembly of the present invention is more effective than HEPA filters and UV light at eliminating pathogens, bacterial, viruses and mold spores. The bipolar ionization assembly of the present invention kills contaminants within a space on contact and is more effective than HEPA filters in reducing active microorganisms. A HEPA filter only traps particles down to 0.03 microns in size. Microbes smaller than 0.03 microns, which includes many viruses like Coronavirus, will pass directly through the HEPA filter and be recirculated into the space. Furthermore, a HEPA filter can only trap contaminants, and cannot treat the source of the contaminants. HEPA filters are not only ineffective on odors, gases and volatile organic compounds (VOCs), but also restrict airflow of the commercial portable air conditioner, making it less efficient on the cooling system. HEPA filters need to be replaced regularly and are expensive. The inventive commercial portable air conditioner with bipolar ionization assembly is maintenance free and requires no filters, thereby eliminating the cost and downtime associated with filter replacements.
Similarly, Ultra Violet light (UV) used in commercial portable air conditioners is limited in effectiveness. The effectiveness of UV light disinfection of air is dependent upon contaminants being exposed to the light long enough for the contaminants to be treated. Most commercial portable air conditioners move the airstream at 400 cfm allowing the contaminant to only be exposed to UV for a fraction of a second, which is ineffective in killing contaminants such as bacteria and viruses which need to be exposed to UV light between 15-30 minutes for effective treatment. Furthermore, UV light is ineffective and does not reduce airborne particulates, odors, gases and VOCs from the air. Costs are also an issue and include yearly maintenance and costly replacement of the UV bulbs.
The inventive commercial portable air conditioner with a bipolar ionization assembly in accordance with the present invention distinguishes over existing commercial portable air conditioners using HEPA filters and UV light for contaminant removal, which are not only substandard, but also inefficient and ineffective for complete microbe and odor removal from air and surfaces. The present invention kills viruses, mold spores, and bacteria both airborne and on surfaces. It eliminates odors at their source while providing cooling in a safe and efficient manner. The commercial portable air conditioner with a bipolar Ionization assembly and combination of cooling and sanitizing the air is safer, more effective and more efficient than any available commercial portable air conditioner on the market.
Referring now to the Figures, an exemplary embodiment of the present invention is described.

The air conditioner may comprise a housing 120 for an evaporator or entry grill 130 for ambient air, condenser grill 140 for hot air discharge, and cold air supply discharge grate or nozzles 150 and an evaporator coil 166. Though not shown in the figures, the air conditioner may also include a refrigerant circuit compromising a compressor, and a condenser coil. Rotational castors or wheels 170 are affixed to the housing making it completely mobile in all aspects. A fan motor forces air through the evaporator coil 166 positioned within the housing chamber 120 to supply conditioned air into the space.
The air conditioning system further comprises a bipolar ionization assembly 110 positioned at the air stream of the intake of the evaporator side of the blower motor housing. A bipolar ionization assembly unit may be any suitable bipolar ionization assembly, which may be obtained from a commercial distributor or dealer. The commercial air conditioner or spot cooler would be disassembled, and the evaporator blower intake 182 would be located.
As shown at
The bipolar ionization assembly is attached to the blower intake of the evaporator housing. The bipolar ionization must be in the air stream of the evaporator section of the commercial portable air conditioner. It may be placed upstream or downstream within the airstream and still operate properly as intended.
The present invention incorporating a sanitizing bipolar ionization assembly within the portable air conditioner causes bipolar ionization of a gas creating plasma that is not in thermodynamic equilibrium because the ion temperature is lower than the electron temperature. This plasma is referred to as ‘cold plasma’ or ‘non-thermal plasma’ because it occurs at room temperatures. Cold plasma has many benefits which include, but are not limited to, the ability to kill harmful pathogens including bacteria, mycoplasma, viruses, mold and odors. Additionally, cold plasma helps with a reduction of Volatile Organic Compounds (VOC's) and a reduction of particulates in the air including known allergens. Furthermore, cold plasma also reduces or eliminates static electricity in the air.
The present invention may be used in numerous applications and industries. Currently, commercial portable air conditioners are sold and rented for short or long term cooling or heating applications. The present invention may be used when commercial HVAC systems break down or need maintenance. During such a downtime, the commercial portable air conditioner of the present invention may be used to cool buildings or facilities, nonlimiting examples of which include computer rooms, offices, classrooms, hospitals, health & rehabilitation facilities, medical facilities, and healthcare labs. The healthcare industry specifically uses commercial portable air conditioners within their facilities. Unlike existing alternatives, the present invention offers a safer product which provides sanitizing and elimination of odors, and dangerous microbes, viruses, bacteria and mold spores.
Nonlimiting examples of additional applications of the present invention may include food preparation, medical/pharmaceutical industries, automotive repair, construction and air remediation. For example, the present invention may be used in food preparation and processing to limit and eliminate germs while keeping food items cool. Uses in the medical and pharmaceutical industries may include sanitizing and sterilization of equipment. The present invention has practical applications in the automotive repair industry to eliminate toxic exhaust odors and VOCs in repair shops and automotive dealerships. The construction industry could also benefit from using the present invention by keeping job sites cooled and conditioned while removing odors from dangerous paint fumes and adhesives.
Further, the inventive commercial portable air conditioner with a bipolar ionization assembly has an important application as a remediation air scrubber, as an alternate air scrubber which may be used to remove particulate form the air. The remediation industry uses indoor air quality equipment such as HEPA air scrubbers. The present invention can be used in a similar fashion and produce better air quality than a HEPA air scrubber. The present invention distinguishes over all existing commercial portable air conditioners in indoor air quality, sanitization and purification.
In summary, the present invention provides an air treatment system comprising an air conditioner; a bipolar ionization assembly; and a power supply.
