OZONE AIR GENERATORS FOR THE CONTROL OF AIR QUALITY

Ozone Air Generators is a Leading-Edge Technology designed to control Indoor Air Quality and recently have been utilized widely in several buildings. Ozone generators produce the ozone and are used as air cleaners for commercial and residential applications. Specifically, Ozone Generators deodorize, disinfect, kill or remove dangerous or irritating airborne particles in indoor environments.

Ozone is the principal element of the ozone layer, which traps the sun’s heat and is essential to life on Earth. Unlike breathable, stable oxygen molecules, which are composed of two oxygen atoms, ozone is composed of three. The third oxygen atom in ozone can easily detach from the ozone molecule and reattach to other substances, altering their chemistry. Ozone generators produce the gas in large enough quantities that unstable organic compounds will react with the gas and, supposedly, be altered so that they will no longer be irritating or dangerous.

POOR IAQ CAN THREATEN THE HEALTH

 

Most people spend over 90% of their time indoors, not knowing that the air they are breathing may be more polluted than the air outside. The indoor air pollution levels can be 100 times higher than the air outdoors.

Breathing contaminated air puts the health at risk. So take control of your indoor air quality by reducing pollutants that can contribute to headache, lung irritation and fatigue as well as more long-term conditions such as asthma, allergies and infectious diseases.

Dartek offer a range of ozone air purification technologies and solutions to almost any airborne problem, condition or application. Learn more about some of our most popular systems such as In-Duct Type or Injection Type Ozone Generator Systems for the entire air conditioned space.

The ozone is injected into the central air conditioning system. The ozone generators are controlled by sensors activated by excessive VOC concentrations and turned off by excess ozone concentration sensors. Carbon dioxide sensors call for makeup air if the carbon dioxide concentration exceeds a standard set-point. The air conditioning system is large and energy- consuming because outdoor temperatures routinely exceed 40 deg C in the warmer months. All systems and components are controlled by a computerized building control system (BCS). The ozone monitors keep the ozone concentrations in the occupied areas to less than .05 ppm.

The VOCs to be minimized by the ozone treatment include bacteria, virus, including the coronavirus, cigarette smoke, jet fuel and exhaust fumes in the makeup air, and building chemical fumes such as from paint, carpets, and cleaning chemicals. During the SARS epidemic of 2003, ozone sterilization was successfully used to purify environments infected with the deadly Coronavirus, SARS-CoV-1, the virus which causes the SARS disease. 

The conditioned air residence time in the passenger areas is about 15 minutes or about the half-life of the ozone in such environments. Because the ozone concentration drops about 90% from supply ducts to return ducts instead of about a 50% drop predicted by half-life, we can see that much of the ozone has reacted with VOCs.

An unexpected finding was that the makeup air could be cut by 50% without compromising the carbon dioxide concentration criterion. The ozone is destroying the VOCs sufficiently to significantly reduce the makeup air without reducing the building’s air perceived quality. This translates to great energy savings because cooling the very hot makeup air requires large amounts of energy. The indicated energy saving should recover the cost of the ozone equipment in about one year.

After operation of the system for several years, the preliminary findings were:

  • Passengers, Guests and employees note a pleasing air quality without the distinct smells that are often found in busy airports.

  • The savings of ozone replacing carbon filters are very large. Carbon filters have high replenishment costs and occupy a lot of valuable space.

  • The energy savings in reducing the makeup air requirement are significant.

Other HVAC system maintenance costs are reduced such as less cleaning of the ducts due to virtually no mold and mildew accumulation.
