Abstract
The present invention relates to a system and method for treating air and water in refrigerated spaces using ozone-based disinfection. The system includes an electrolytic ozone generator configured to produce gaseous ozone from water and an air circulation subsystem to create an oxidizing airflow within a housing. The airflow is directed across a titanium dioxide-coated surface to reduce ozone concentration before reentry into the refrigerated space. A controller manages disinfection and purification modes, enabling safe air treatment in environments such as ice machines, walk-in refrigerators, and consumer appliances. In some embodiments, aqueous ozone is also routed to ice makers or water dispensers for waterline disinfection. Optional features include manganese dioxide treatment modules for hydroxyl radical generation, automated door locking during disinfection, and ozone sensors for safety compliance. The invention enables programmable, sensor-driven, and safe disinfection cycles without requiring external ozone emission, supporting food safety and occupant protection.
