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.

LightSources provides only the highest quality germicidal UVC lamps, proven to outlast and outperform comparable lamps. The experts at LightSources can help design the most effective and most economical UV lamps for air purification systems for use in any business, government facility, home, or other building.

185nm UV Lamp for Ozone Disinfection


 185nm UV Lamp generates ultraviolet energy at 185nm which is proven to effectively produce ozone, a natural sanitizer and deodorizer. A 185 nm UV light produces UV energy in wavelengths shorter than 220 nm which decompresses oxygen, O², to produce ozone, O³. UV germicidal lamps are designed to emit the most effective wavelength of UV radiation, measured in nanometers (nm). 185 nm lamps produce ozone, while 254 nm is an optimal wavelength to target the DNA of viruses, fungi and bacteria.

Ultraviolet radiation is proven to instantly penetrate the cells of harmful, disease causing microorganisms and rearrange the genetic material to render the cell unable to replicate. These harmful germs including protozoa and algae are unable to reproduce and are considered dead. UV germicidal lamps are proven to be highly effective in many surface, air and water disinfection applications with 185 nm ozone lamps providing many benefits.

Low Pressure and Medium Pressure Germicidal Lamps

The two main types of UV germicidal lamps are low pressure and medium pressure Mercury discharge lamps. Some low pressure germicidal lamps will look very similar to typical fluorescent lamps although the glass tube does not contain a fluorescent phosphor. The glass is also made of either soda lime glass or fused quartz as opposed to an ordinary borosilicate glass in typical fluorescent lamps.

This is to allow the optimum wavelength produced by a Mercury arc of either 185nm or 254nm of UV light to pass through unmodified. Low-pressure Mercury discharge lamps will still produce a visible light due to Mercury radiation bands.

Medium pressure Mercury discharge lamps look very similar to a high intensity discharge (HID) lamps and produce a broadband of UVC radiation rather than a single, narrow band line. These broadband UVC germicidal lamps produce a bright bluish white light and are common in many industrial water treatment applications due to the intense radiation source.

Low Pressure Amalgam UV Lamps

Low pressure Amalgam UV lamps provide stable performance over a wide range of ambient temperature changes with 3 to 4 times higher power density. Amalgam lamps are preferred for long-term applications and are available with either spot or pellet Amalgam technology. Spot Amalgam technology uses Mercury Amalgam applied to the inner surface of the lamp, whereas pellet Amalgam technology has Mercury Amalgam on the outside of the lamp arc.

Amalgam lamps provide some benefits over other lamps with the vapor pressure controlled by location and composition of Amalgam and allow for higher lamp current operation with robust filaments.

Ozone Producing 185 nm UV Lamp Benefits

Ozone Air Purification – Ozone Carries Through the Air

Ozone producing 185 nm UV lamps offer additional benefits and are required to oxidize specific organic compounds. One of the major advantages of ozone disinfection lamps is that ozone is carried through the air to places where UV radiation does not directly reach. 185 nm UV light is used in many UV air purification systems to effectively sanitize and clean the air in many HVAC systems.

Ozone Water Purification – Stronger than Chlorination

185 nm lamps are also very common in many water sterilization applications. Ozone is proven to be very effective over a wide range of pH environments and reacts quickly with viruses, bacteria and protozoans. Ozone provides a very strong oxidizing power and a short reaction time, with stronger germicidal properties then chlorination in many applications. Ozone does not add harmful chemicals to the water and eliminates many protozoans the chlorine does not such as Giardia and Cryptosporidium.

Ozone Oxidation – Powerful Water Disinfection

Also provides excellent oxidation in disinfection properties which makes it popular in drinking water treatment systems. 185 nm lamps are convenient in that ozone may be added to water treatment systems at several points such as during pre-oxidation, intermediate and final disinfection treatment processes. Ozone water disinfection is used worldwide in many applications including ballast water treatment systems for ships which are globally enforced to protect the planet’s oceans.
