The Application of Cool Air from Thermoelectric for Reduce Temperature in Ozone Tube of Ozonizer Affecting to Ozone Gas Quantity

This research paper presents to the temperature reducing in ozone tube of ozonizer by applied thermoelectric for producing cool air. To observe the amount of ozone gas produced is ozonizer using inverter high voltage high frequency of half-bridge type at switching frequency 25 kHz and controls its operation using pulse width modulation (PWM) technique and can produce high voltage at 3 kV for supply to the ionizing bar at the highly non-uniform electric field ozone tube of two level insulator cylindrical, which in the first hour of the test machine can produce ozone gas at 216.8 mgO 3/hr of temperature is 29°C. When researcher use cool air from thermoelectric to blow the bar of ozone, it can produce ozone at 379.5 mgO 3/hr of temperature at 25°C. Thereby producing a cooling air by thermoelectric result in temperatures drop. As a result, the rate of decomposition of ozone gas gets lessening and can produce higher ozone gas. Therefore, future research will be designed to produce ozone gas from the cooling system thermoelectric to develop a real application for removal of odors from the food industry.
