  1. 1. Trane Catalytic Air Cleaning System(TCACS)Available to Trane Dealers in British ColumbiaDate
  2. 2. Indoor Air Quality – Air Cleaning2 Trane Catalytic Air Cleaner
  3. 3. Benefits of Improved Indoor Air Quality Keep buildings clean • Dust Help HVAC system Particles • Allergens • Smoke performance Minimize adverse health effects • Chemicals Contaminants Gases • VOCs • Odors Code or process requirements • Virus Risk Reduction Micro- Biological • Bacteria • Spores 3
  4. 4. Indoor Air Quality - What’s Changed?ASHRAE Position Paper, June, 2009• Acknowledges that HVAC systems play a role in the dissemination of diseases in buildings• Key points: – Infectious diseases can be transmitted via an airborne path – Designers have a responsibility to minimize that potential  Dilution ventilation  Building pressure control  Filtration  Oxidative technologies,  UVGI, PCO4 Trane Catalytic Air Cleaner
  5. 5. Public Awareness of Air Cleaning – What’sChanged?• 3M has been a forerunner with ads depicting their Filtrete® brand capturing more airborne particles and organisms than lower rated filters. Filtrete® dominates the retail high-end filter market.• The H1N1 influenza pandemic showed how easily the virus can be transmitted among humans. Pictures of millions wearing face masks have solidified the perception that germs are airborne and filtration can help prevent infection. “In our study, we revealed, to our knowledge for the first time, the presence of airborne influenza virus particles in a health care environment”. CDC NIOSH, Feb. 2009 Airborne Disease: Now a Forethought 5 Trane Catalytic Air Cleaner

  11. 11. II. Ultraviolet Germicidal Irradiation (UVGI) Microbiological Inactivation Most• C-band ultraviolet; 254 nm susceptible virus• Effectiveness is dose-related (intensity x time) vegetative bacteria• “Killing” dosage varies widely by species of microbe mycobacteria• Designed for specific duty bacterial spores o Surfaces: low intensity, effective o On-the-fly “kill:” difficult to achieve fungal spores Least susceptible11 Trane Catalytic Air Cleaner
  12. 12. Vapor Phase (Gaseous) Air Cleaning • What type of gases are floating around? – Irritants ( Aldehydes, Ozone, CO, Methane) – Odorous (cleansers, cooking) – Corrosives (SO2, Chlorine) • What are common indoor sources? – Paints and solvents – Combustion sources – Sewer Gas – Plastics, furniture and carpets – Printers and copiers – Aerosol sprays – Cleaning products and disinfectants – Pesticides and bug repellents – Air fresheners – Mold (Toxins) – Adhesives, caulk – People – Cooking Odors12 Trane Catalytic Air Cleaner
  13. 13. Vapor Phase – Solutions • Source Control • Ventilation • Removal/Reduction Chemisorption Technologies – Adsorption – Chemisorption – Catalytic Conversion Adsorption Photo-Catalytic Oxidation13 Trane Catalytic Air Cleaner
  14. 14. III. Photo-Catalytic Oxidation (PCO) • Catalytic Conversion – Newest technology in commercial HVAC market – Analogous to car catalytic converters – Conversion process: changes molecular structure of contaminant to less toxic substances – Needs an energy source and a catalyst to force chemical reactions in airstream – Works on organic compounds by breaking the carbon chains14 Trane Catalytic Air Cleaner
  15. 15. III. Photo-Catalytic Oxidation (PCO)• UV light creates photons, a form of light energy• Photons are “catalyzed” by the TiO2 forming hydroxyl radicals• Radicals last less than 1/10 of a second and react with carbon-based compounds• Organic compounds can be reduced to CO2 and H2O Graphic Courtesy of Steven Welty, Green Clean Air © 201015 Trane Catalytic Air Cleaner

  21. 21. Air Cleaning Needs in Hospitals• 36 states now require some form of reporting for hospital acquired infection (HAI).• Medicare is no longer required to reimburse for medical expenses due to HAI’s.• Lawsuits against hospitals causing infection are up 50% in the last 10 years. Hospitals today face increased financial exposure21 Trane Catalytic Air Cleaner
  22. 22. Air Cleaning Needs in Schools• The EPA has citied that poor indoor air quality can impact the comfort and health of students and staff, which, in turn, can affect concentration, attendance, and student performance.• In 1999, Indoor air quality (IAQ) was reported to be unsatisfactory in about one in five public schools in the United States, while ventilation was reported as unsatisfactory in about one-quarter of public schools -National Center for Education Statistics of the Department of Education• Growing concerns with – Crowded classrooms – Hygiene issues – Absentee rate – Teacher attendance – Improved protection against outbreaks Schools today have added concerns for child safety Trane Catalytic Air Cleaner
  23. 23. Air Cleaning Needs in Airports• Increasingly, airport management the TSA and FAA are showing interest in the health impacts from combustion engines, biological contaminants and other airport related sources of airborne toxins.• Sources of hazardous air pollutants and biological contaminants – Aircraft: Jet Engine Exhaust – Ground Source Equipment: Diesel Engine exhaust, De-icing machine exhaust – Ground Access Vehicles: Diesel engine exhaust – Stationary sources: clean and sanitizing vapors, food prep odors – People: perfumes, odors, viruses, bacteria Trane Catalytic Air Cleaner
