TECHNIQUES FOR DISINFECTION AND DEODORIZATION OF INTERIOR OF BUILDINGS USING OZONE

The present invention solves the problem of efficiently disinfecting and deodorizing indoor areas with ozone, without introducing health risks to people inside these areas. A cold plasma ozone generator generates ozone that is distributed to one or more rooms where disinfection and/or deodorization is needed. The distribution of ozone is regulated by valves controlled by a main control module collecting data from ozone concentration and IR motion detectors installed at rooms where the ozone is distributed, and other sensors in the ozone generator, and by using a schedule associating information derived from the sensory data, with dates, time slots, and desired ozone concentrations. If ozone concentrations exceed predefined levels, ozone generation and/or distribution is interrupted. When malfunctions occur, either the main control module commands the system to enter in emergency shutdown or lockdown, or a local control module or the ozone generator take control of the ozone generation and distribution.
