Air disinfection type ozone generator selection. Since ozone can only be produced locally, the most economical and technologically mature way to generate ozone is corona discharge, and the ozone generators used for air disinfection mostly use the high-frequency discharge mode of ceramic sheets, which has simple structure and high performance. It has the advantages of reliability, low operating cost and flexible adjustment.

Safety of ozone air disinfection. Ozone safety In extensive animal and human experiments, the main exposure route is inhalation. Continuous and long-term inhalation experiments show that ozone is not carcinogenic (NTP, 1995); but it has obvious stimulating effects on the respiratory system of animals and humans. Exposure to the environment can affect respiratory function. Therefore, we suggest that the use of ozone to sterilize the air should be carried out in an unmanned environment, and personnel can only enter after half an hour of disinfection.

The ozone sterilizer is placed inside the central air-conditioning air supply duct or return air duct, and the ozone generated by the ozone sterilizer is transported to the workshop that needs to be sterilized by using the wind power of the air conditioner. This ozone sterilizer is easy to use, and the ozone gas can also be conveniently delivered to the workshop that needs to be sterilized.

However, because it is placed in the air duct of the air conditioner, it is not easy to detect when a fault occurs, and it is also inconvenient to take it out for maintenance. At the same time, ozone gas may have certain oxidation and corrosion effects on air ducts made of galvanized iron, air conditioner motors, copper parts, electronic components, and rubber seals.

Hang the ozone sterilizer on a high part of the wall in the workshop, and blow the ozone gas to the workshop through the "window" or "sprinkler" on the ozone sterilizer. Due to the limitation of structure, volume and other aspects, this kind of ozone sterilizer actually blows ozone very close, usually no more than 3 meters, so it cannot sterilize far away from the workshop.
