Indoor Air Quality Solutions

We provide customized solutions for improvising Indoor air quality & also achieving energy efficiency. We have successfully implement disinfection treatment solution for Hotels, Hospitals, Office Buildings IT Parks, Banks, Schools, Commercial Buildings, Malls, Exhibition Centers, Multiplexes, Industries. Addressing issues like Indoor Air Quality, Odour, Allergy, Smoke, Dusk, Cross Infection, etc.

How Green is your Indoor Air?
Airborne Diseases are 2 to 10 times higher in Indoor air then outdoor air. Indoor Air Quality is an important determinant of population health and well being. Because people spend most of their time in indoor spaces then out door. Results of numerous studies have demonstrated that Building Related Symptoms (BRS) can adversely affect productivity and occupant well being.
We have successfully engineered strong oxidizing & disinfecting properties of OZONE for Indoor air treatment.

Ozone Generator is effectively used for Indoor Air Quality Solution

Environment Benefits Of Ozone Generator System
Chemtronics OZONE GENERATOR SYSTEM ACHIEVES:
• Dramatic reduction in buildup of VOC’s.
• Dramatic Reduction in Odours.
• Depletion of Microbial Colonies (Fungi) in Ducts and AHU cooling coils. Eliminates duct cleaning.
• Oxidize air borne bacteria.
• Address Cross Infections.
• Keeps the Indoor Air pure & healthy

Economic Benefits Of Ozone Generator System:
Reduction in Capital Cost
Reduction in fresh air intake will reduce the overall HVAC plant capacity sizes:
1. Chiller, Cooling Tower.
2. Condenser water and chilled water pumps.
3. Pipe sizes and Insulation.
4. Electric / Stream Duct heaters.
5. Electrical Panel & Cables.
6. Stand by diesel generator.
7. Plant room space.

Reduction in Operating Cost
Reduction in fresh air intake will reduce the Cooling load.
Reduction in HVAC capacity will result in the following:
1) Reduction in Energy consumption to run HVAC System
2) Reduction in Water consumption to run HVAC System
3) Cost of Maintenance (Labour and Material)

Research indicates that improvement in Indoor Air Quality (IAQ) :
• Increases productivity by 5-10 % & more.
• Reduces asthma by 8% - 25%.
• Reduces other respiratory illnesses by 23 % - 76 %.
• Reduction in Fresh Air Intake Reduces HVAC over all plant capacity & Operating cost by 15- 20% Result of Achieving

INDOOR AIR QUALITY

Green Building Projects
Indoor Air Quality is an important parameter for Green Building Projects and we use ozone generator technology as the Indoor Air Quality Solutions for Green Solutions.

Sustainable Building Solutions
Ozone Generator used in the HVAC Systems will result in energy efficiency which is a Sustainable Building Solutions.

Major impurities in Indoor Air Environment are:

Volatile Organic Compound (VOC)
In Indoor Environment Toxic Gases are emitted from wide variety of sources:
» Building Materials,
» Cleaners, Plastics,
» Wood Products,
» Paints, Carpets,
» Polishers,
» Deodorants, etc.

Volatile Organic Compound (VOC)
It adversely affect to:
Allergy, Asthma, Eye & Nasal irritation, Affect respiratory tracts, etc.

Carbon - di – oxide - Co2
In an indoor environment human being Exhale Carbon dioxide it cannot be reduced or oxidized.
It is not a toxic or carcinogen but a high level of CO2, causes:
» Headaches, Restlessness,
» Difficulty Breathing, Sweating,
» Tiredness, Increased Heart Rate,
» Elevated Blood Pressure, etc

Odor
Odour is a major Irritants & it is cause from various sources:
» Food Odour
» Body Odour
» Mold, Fungi & Microbes
» Cleaning Chemical Odour, etc
This is a residual odor & difficult to dilute from conventional method.

These are collectively known as“SICK BUILDING SYNDROME”

To address Sick Building Syndrome (SBS) the AHU systems take “Outdoor Air” to dilute Volatile Organic Compound (VOC) and reduce Carbon dioxide (CO2) within acceptable limits.
Conventionally Fresh Air is used to improve Indoor Air Quality (IAQ)
» Fresh air is not cheap!
» Hot and humid air needs to be cooled down to room temperature.

Hidden Cost of Fresh Air taken by Air Handling Unit in an HVAC System:
Load profile of fresh air
» 60% to cool moisture … wasted energy
» 28% to cool nitrogen …..wasted energy
» 12% to cool oxygen …..the only useful component in fresh air.

“Energy Consumption- 150 CFM of Fresh Air will require 1ton of cooling load. (Approximately)”

Position of ASHRAE on reducing fresh air intake:

“ASHRAE approves reduction in fresh air, if chemical contaminants in air are removed”.
We refer you to the following sections of ASHRAE62-99:
“Procedure for use of cleaned recirculated air: The amount of outdoor air may be reduced by recirculating air from which offending contaminants have been removed or converted to less objectionable forms. Formaldehyde, for example may be oxidized to water and carbon dioxide. The amount of outdoor air depends on the contaminants generated in the space, etc ......”.

ASHRAE Standards
» ASHRAE Ventilation code no. 62-1999.
» Minimum 15 CFM per person fresh air is required.
» Minimum of 30 CFM fresh air is required if smoking is permitted.

How to reduce “Fresh Air”

» By using controlled injection of ozone.
» Oxidation of Volatile Organic Compound (VOC) is performed by ozone and not by oxygen of the fresh air.
» Ozone is more powerful oxidizing agent than oxygen.
» In the presence of a more powerful oxidant, less powerful oxidant does not have the chance to perform oxidation, until no more of the former is available.
» Oxygen of the fresh air is preserved and not spent in performing the task of oxidizing the Volatile Organic Compound (VOC), which is now transferred to ozone.
» Available oxygen is now used entirely to maintain Carbon-di-oxide.
» Intake of fresh air is reduced drastically. Thus fresh air requirement goes down to 5CFM or less per person.

ASHRAE Standards for Indoor Air Quality
• ASHRAE Ventilation code no. 62-1999.
• Minimum 15 CFM per person fresh air is required.
• Minimum of 30 CFM fresh air is required if smoking is permitted.

Safety Measures of Ozone Generator
• Ozone sensors, VOC sensors & Timers are used to monitor air quality.
• Machines are interlocked with AHU to provide safety operations.
• Special Di-Electric with coating and air cooling ensure long life to electrode.

Advantage of maintaining Indoor Air Quality in office Building:
Indoor Air Quality improves the efficiency of the occupants.
Indoor Air Quality reduces fatigue.
Indoor Air Quality improves the productivity of occupants.
Indoor Air Quality results in reduced cross infection.
Indoor Air Quality reduces Allergy.
Indoor Air Quality reduces the Astama.
Indoor Air Quality is a green environment initiative.
