UV Light Air Conditioner Benefits


 Weighing the cost against the benefits, it is difficult to find a downside to installing a UV light air conditioner purification system in any commercial, industrial, municipal, medical, or residential building. UV germicidal light, specifically at the frequency of 253.7 nanometers (commonly referred to as 254 nm), effectively eliminates a host of pernicious microorganisms, such as fungi, bacteria, viruses, molds, spores, parasites, and dust mites.

The result is, at the very minimum, cleaner air for residents, employees, visitors, and others throughout the structure serviced by the air conditioner. In addition, UV germicidal lamps prevent build up on equipment which prolongs the useful life of air conditioning systems and enhances efficient operation.

UV Light AC System Proven to Reduce Fungi

UV light air conditioner purification systems provide many benefits and efficiencies. UV radiation is extremely effective at eliminating harmful pathogens that can collect on air conditioner units and spread through circulated air. In a recent scientific study evaluating the effectiveness of UV radiation to eliminate fungi in air handling units, a 286,000-square-foot office building in Oklahoma was equipped with a UV system on the main air handling units of two floors while two other floors had no lamps installed. Readings were taken from the study floor and the control floor to detect the concentration levels of mold and fungi since installation.

More than a dozen fungi species were present in May prior to installation of the UV system. When taken again in September, the readings on the floor with the UV system had decreased, while nearly every taxon increased its concentration on the control floor, in a couple of instances nearly 100-fold.

Health Benefits of UV Light for Air Conditioning Systems

UV lights in air handling units and air conditioner systems remove harmful pathogens from the units and from circulated air which provides significant health benefits. Some of the symptoms and ailments alleviated by the purified air include common colds; eye, nose, and throat irritation; allergies; headaches; nausea; COPD; bronchitis; asthma; lung infections; pulmonary disease; autoimmune deficiencies; and cancer.

The positive ripple effects of installing a UV air sterilization system are legion, and many of the benefits are long-term:

·        Freeing a workplace from airborne germs, pollutants, and irritants makes for a healthier workforce, and consequently decreases absenteeism and increases productivity.

·        UV purification systems have been proven to remove many industry-specific toxic chemicals and volatile organic compounds (VOCs) produced during business operations.

·        At 254 nm, the UV light produces no ozone, which can erode copper wiring and tubing. UVC ozone lamps are available that with proper installation, provide air sterilization and odor control.

·        UV light prohibits the accumulation of microorganisms, mold, and mildew that can clog the passageways of an AC system, making the motor work harder and shortening the useful life of the mechanics.

·        With the destruction of mold and mildew, their associated odors are eliminated.

·        The UV germicidal light system lowers energy costs by continuously cleaning the air conditioner components of mold and biofilms, particularly the coils, drain pans, and vent surfaces.

·        UV light systems are extremely low maintenance, saving time and money.

·        UV systems can work at optimum efficiency throughout a wide range of temperatures, from roughly 40°to 120° F (4° to 48° C). LightSources can custom-design systems to work in higher temperatures as required.

HVAC UV Bulbs Improve Indoor Air Quality

Many people want to know if HVAC UV bulbs really work to improve indoor air quality in heating, ventilation, and cooling (HVAC) systems. HVAC UV light bulbs can be highly effective at killing bacteria, viruses, mold, mildew, and fungi when using the right type of germicidal UV bulbs and with the proper installation.

Do HVAC UV Bulbs Really Work?

HVAC UV light bulbs prevent the accumulation of harmful microbes on internal components such as heat transfer coils which are exceptionally vulnerable to contamination due to the dark environment combined with condensation. Using HVAC UV light bulbs helps to improve the condition of mechanical components and reduce necessary maintenance by maintaining clean and sanitary parts free from microbial buildup.

HVAC UV bulbs also improve indoor air quality by sanitizing the air and inactivating mold spores that pass through HVAC ductwork. Ozone lamps in HVAC systems can also reach where direct UV exposure cannot and eliminates volatile organic compounds (VOCs) and foul odors from the air. Using UV bulbs in HVAC systems helps prevent harmful microorganisms from circulating throughout the ductwork in your home or office.

UVC Germicidal Bulbs for HVAC

HVAC UV light bulbs must be UVC germicidal bulbs to provide sterilization effectiveness. Ultraviolet light includes wavelengths in the range of 100 to 400 nm and is divided into three bands:

  • UVA is the longest wavelengths at 315 to 400 nm
  • UVB is in the range of 282 315 nm
  • UVC wavelengths are in the range of 100 to 280 nm

UVC radiation, specifically in the range of 254 nm, is proven highly effective at eradicating microorganisms quickly upon exposure by altering the DNA and preventing harmful germs from replicating. UVC radiation in this wavelength is proven to eliminate many types of harmful viruses and bacteria, including stubborn antibiotic-resistant bacteria and harmful coronaviruses, including the SARS-CoV-2 virus that causes COVID-19.

Far UVC is an even shorter wavelength in the range of 222 nm and is also effective for surface and air sterilization applications, and is safer for human exposure. 254 nm lamps are used in many surface, water, and air sterilization applications, although they should not be used in direct contact with human exposure. 222 nm lamps are providing alternative solutions with effective sterilization and safer usage.

HVAC UV Bulbs Improve Indoor Air Quality

UVC lamps for HVAC systems improve indoor air quality when installed by a professional to ensure safe and effective installation. HVAC professionals have knowledge of the correct placement and direction of UV bulbs for effective sterilization, considering the humidity and temperature levels in the home. Upper-Room Ultraviolet Germicidal Irradiation (UVGI) systems are located above occupied spaces and kill airborne pathogens for cleaner, healthier air.

UVGI and Air Filtration Filters

The Centers for Disease Control and Prevention, CDC, recommends a layered approach with the proper ventilation to mitigate the spread of disease and lower exposure. Using High-Efficiency Particulate Air (HEPA) is important to trap larger particles which could shield microorganisms from UV radiation, reducing effectiveness. UVGI provide effective sterilization but should be used in conjunction with proper air filtration and cleaning measures, and they do not replace the need for HEPA filtration.

HVAC UV Light Bulb Systems

HVAC UV bulbs provide two different types of sterilization, cleaning the coils and equipment for longer-lasting, cost-efficient operation and air sterilization in HVAC ducts. UV bulbs for HVAC disinfectants sterilize the air as it cycles through return ducts. Interior reflective surfaces maximize UVC light effectiveness in all directions. For sterilizing coils, UVC lamps are installed to target vulnerable components, including coils, filters, and condensation pans. UV light for HVAC systems prevents microbial growth in hard-to-reach places, including seams, grooves, and edges.
