Problems solved by technology

Therefore, the wind composed of fresh air and indoor air cannot effectively kill viruses and bacteria in the existing device, which may cause cross-infection of various epidemic diseases in the crowd
[0004] The current central air-conditioning air disinfection methods mainly include adding an ozone generator and spraying various disinfectants. The disadvantage is that the purification and disinfection of ozone is effective in a fixed area, and it is difficult to adapt to the changing building environment and has peculiar smell. , overdose can be detrimental to human health
All kinds of disinfectants are harmful to human health

Abstract

A disinfecting unit able to kill coronavirus for the ventilation system of central air conditioner features that an efficient antibacterial filter made of non-woven fabric is used, the C-band ultraviolet lamp is installed in air returning pipes, and the TiO2 photocatalyst is sprayed on air inlet of room. Its advantages are high antibacterial effect and dusting effect, low resisance, and no secondary pollution.

Description

Technical field: [0001] The invention relates to air purification, disinfection and sterilization, and specifically refers to the purification and disinfection of circulating air in a central air-conditioning ventilation system, that is, the application of clean technology. Background technique: [0002] The central air conditioners widely used in modern buildings are mainly divided into two types: water-cooled and air-cooled. The design principle and general structure of the ventilation system are consistent. The air circulation process is: the fresh air is inhaled by the fresh air outlet, enters the ventilation shaft, and then passes through the coarse-effect filter in the fan room. The filtered air passes through the fan coil and is compressed into the required hot and cold air in the central air conditioning unit. And after humidification, it goes to the room from the air supply port through the air supply pipe. Part of the indoor air is discharged from the building thro...
