Reducing Ventilation Air Requirement by Ozone Dosing

Reduction Of Air Ventilation Requirement Ozone Dosing

Oxygen outdoors oxidized Volatile Organic Compounds (VOC) and odours. Air conditioning also dilutes CO2. Minimum ventilation requirement 15 cfm per person-Smoking rooms and 30 cfm per person, if Smoking is permitted. The load on air conditioning system increases with ventilation. The use of controlled injection of ozone can help reduce the amount of fresh air. Ozone is a powerful oxidant, which removes the odor, VOC and even mushrooms by oxidation.

This reduces oxygen demand in the form of ventilation and conditioning, mainly required for dilution of CO2. This is much less of a requirement, therefore, the fresh air, can modulate rationally to 5 cfm or less per person. However, if the residual ozone concentration exceeds limits, ozone is a toxic gas. ASHRAE limit of 0.05 ppm. Plate-type generator of the crown in a duct is auto VOC controller...
