Fabrication of ozone generator for indoor air quality

Ozone generator was fabricated in the size of 40×12.5×12.5 cm³. It composed of 6 ozone tubes, a computer fan, electronic board with variable resistors and adjustable buttons of 7 ozone production levels. The generator was operated in a chamber of 96.5×47×47 cm³ representing a model room met air ventilation standard. At level 1 of operation, ozone concentration in the chamber was to be 0.1 ppm which is obeyed the standard OSHA recommendation for 8 hrs of working. The generator was also tested in a normal room with the size of 4×4×2 m³. Due to low flow of computer fan, the generator was performed to obtain ozone concentration of 0.1 ppm as following: turning on at level 7 for 3 hrs and further on at level 3 until 8 hrs.
