Indoor Air Quality is an important determinant of population health, use of Ozone Generators in HVAC Design will improve the indoor air quality. Ozone being the strongest disinfected, Ozone destroys indoor impurities, helps in reducing Volatile Organic Compound, maintain the require oxygen level & there by improves the Indoor Air Quality.
2. Ozone Generators helps in Achieving Energy Efficiency
Use of Ozone Generator in HVAC will reduce fresh air intake requirement.
How Ozone can reduce electricity consumption & achieve energy efficiency in HVAC Systems:
AHU system takes “Outdoor/Fresh 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).
But, Fresh air is not cheap! Hot and humid air needs to be cooled down to room temperature. 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
Solution to reduce the “Fresh Air Intake”
By controlling injection of ozone.
Oxidation of 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 VOC, which is now transferred to ozone.
Available oxygen is now used entirely to maintain CO2.
Intake of fresh air is reduced drastically. Thus fresh air requirement goes down to 5CFM or less per person.
