Indoor Air Quality - IAQ & SBS

  1. 1. Chemtronics Solution Enhance Indoor Air Quality & Reduce Sick Building Syndrome
  2. 2. Indoor Air Quality - IAQ
  3. 3. 3 Indoor Air Quality Concern Indoor Air Quality (IAQ) is an important determinant of individual’s performance, health and well being. This is because people spend most of their time in indoor then out door Results of numerous studies have demonstrated that Building Related Symptoms (BRS) can adversely affect efficiency, productivity and occupant well being.
  4. 4. 4 Studies on IAQ  Indoor Environment contains variety of visible & invisible contaminants  Airborne diseases are 2 to10 times higher in indoor then outdoor  Fresh Air is restricted in closed environment of doubled glass buildings  Lack of fresh air intake  increased use of artificial synthetic building materials
  5. 5. 5 Indoor Air Contaminations  VOC  ODOR  SMOKE  DUST  CO2  FUNGUS, MOLD AND MICROBES  AIR BORNE BACTERIA
  6. 6. 6 VOC CONSTITUENTS There are more than 100 known VOCs  Most VOC are Hydro Carbon  Contain Carbon, Hydrogen & Oxygen  Susceptible to Oxidization  Oxidization Reduces these to O2, H2O, & CO2
  7. 7. 7 SOURCE OF VOC  Body Excretions  Furniture  Paints, Varnish & Polish  Sticking chemicals  Carpets  Stationary, Printers & Copiers  Cooking  Aerosols & Cleaning Chemicals  Pest control chemical
  8. 8. 8 ODOR ODOR IS MAJOR IRRITANT  TRANSIENT ODOR (Instantaneous)  RESIDUAL ODOR (Retained Odor) Residual odor - Difficult to Remove by Conventional Methods
  9. 9. 9 SOURCE OF ODOR  Food odor  Body odor  Cigarette Smoke  Odor from footwear  Carpet  Furniture Glue  Synthetic Material  Paint, varnish, polish  Cleaning Chemicals  Burnt rubber, plastic, wood, wire  Dead rodent, bird, insects  STP  Odor & Toxicity from outdoor FA  Mold, Fungi & Microbes  Pest control chemicals
  10. 10. 10 SOURCE OF FUNGS, MOLD & MICROBES  Visitors  AHU Ducts  Humidity  Damp Carpets, walls, ceilings, upholsteries  Moist areas  Dirty Footwear  Occupants  Insects, pest, rodents
  11. 11. 11 CO2 CO2 IS NOT VOC Toxic Carcinogenic Odorous High level of CO2 can Cause Headaches | Restlessness | Reduced Concentration | Tiredness Fatigue| Lethargy | Reduced Tolerance | Irritability | Difficulty in Breathing | Sweating | Increased Heart Rate | Elevated Blood Pressure
  12. 12. 12 SOURCE OF CO2 In an indoor environment human being exhale CO2 Carbon Dioxide cannot be filtered, adsorbed, reduced or oxidized. Carbon Dioxide has to be neutralized with oxygen
  13. 13. 13 These are collectively known as “ SICK BUILDING SYNDROMES ”
  14. 14. 14 • Headache, Reduced Concentration • Reduced Tolerance, Irritability, Restlessness • Eye Irritation, Eye watering • Asthma, Nose & Throat Irritation, Cold & Cough • Increased Heart Rate, Elevated Blood Pressure • Verity of Allergies, General Fatigue, Sweating, Lethargy Sick Building Syndromes are
  15. 15. 15  Reduce VOC Reduce / Remove Odor Reduce / Eliminate Fungus, Mold Reduce / Eliminate Airborne Bacteria & Viruses Lower / Maintain Carbon Dioxide levels TO ADDRESS “SBS”
  16. 16. 16 To reduce Sick Building Syndrome (SBS) & Enhance Indoor Air Quality (IAQ) Outdoor Fresh air is taken by AHU System CONVENTIONAL SOLUTION
  17. 17. 17  Oxidation VOC & Odor  Lower /Maintain CO₂ up to desired level ROLE OF OUTDOOR FRESH AIR Oxidation 75% CO₂ 25% Role of Fresh Air Oxygen in fresh air is Oxidizing agent; 75% of Oxygen in fresh air is consumed for Oxidation 25% of Oxygen in fresh air is consumed to neutralize CO₂
  18. 18. 18 Structure of fungi, mold, airborne bacteria & viruses Fungi is Hydro Carbon mass with hard protein shell. Its outer Shell is a porous membrane. O2 in fresh air reaches inner hydro carbon mass by the process of osmosis. With this cell metabolism splits it to 2 or more cells. This sets in the process of fungi multiplication CONSTRAINTS, LIMITATION & ADVERSE EFECT Fungi O₂ O₂ O₂
  19. 19. 19 Fresh Air Is Not Cheap Increase in fresh air significantly increases the Air conditioning load. CONSTRAINTS, LIMITATION & ADVERSE EFECT
  20. 20. 20 Controlled Injection Of “ Medical grade Ozone ” in AHU System Chemtronics SOLUTION
  21. 21. 21 VOC & Odor : Ozone is more powerful oxidizing agent then Oxygen; Thus VOCs , Odor & pollutants are efficiently oxidized & 60 – 70 % of oxygen in fresh air is conserved. Advantages of Ozone Injection
  22. 22. Fungi & Mold : Ozone (Even in low concentration), interferes with the process of cell metabolism. This Retards the Process of Fungi & mold multiplication. Over the period of time, Fungi & microbes Colony Depletes Reaching Near Total Elimination 22 Advantages of Ozone Injection
  23. 23. 23 Airborne Bacteria & Viruses : Ozone kills (Oxidizes) bacteria & Viruses almost instantly. Also fungi in ducts & coil Provide Food & Nutrients for Air Borne Bacteria to Grow & Propagate; Ducts, Coil, AHU are Breeding Grounds for Bacteria, When Mold & Fungi Are Eliminated, Food & Nutrients to Air Borne Bacteria & viruses is Deprived Results in Dramatic Reduction in Air Borne Bacteria Advantages of Ozone Injection
  24. 24. 24 Dust (SPM) : For Any Object (dust / suspended particulate matter) to Adhere, Force of Adhesion is Necessary. In AC Duct, Air Travels at Velocity of 1200 to 1500 FPM (365 to 450 M/Min). There Should be Compelling Reason for Dust to Depart this high Velocity Stream and Adhere to Duct Surface. This is Due To Bio Adhesive Force Provided by Fungi Results in Reduction in Suspended Particulate matters Advantages of Ozone Injection
  25. 25. 25 Carbon Dioxide : When 60 – 70 % of oxygen in fresh air is conserved using ozone injection in AHU. More oxygen is now available to neutralize carbon dioxide. This lowers CO₂ levels very significantly. Advantages of Ozone Injection
  26. 26. 26 These multiple effects of Ozone brings “ Freshness in the closed environment ” Completely Eliminates “ SICK BUILDING SYNDROME ” & Greatly Enhances “ Indoor Air Quality ”
  27. 27. 27 Specified Max. IAQ of CO2
