Central air conditioner disinfection and sterilization method

Abstract

The invention discloses a central air conditioner disinfection and sterilization method. A central air conditioner disinfection and sterilization system is sequentially provided with an ionization disinfection and sterilization module, a physical filtering module, an ultraviolet-deep ultraviolet disinfection and sterilization module and a chemical fuming module in the flow direction of air in an air return pipeline of a central air conditioner. The central air conditioner disinfection and sterilization method comprises the following steps that firstly, the air in the air return pipeline of the air conditioner is subjected to electric separation to charge particles in the air and adsorb charged particles; then physical filtration is carried out; and finally, DNA and / or RNA of pathogens are / is destroyed through deep ultraviolet disinfection and sterilization, then the residual pathogens after filtration are killed, and meanwhile, the smoke generating material is diffused into the air return pipeline of the central air conditioner.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a method for disinfecting a central air conditioner. Background technique [0002] There are a large number of microorganisms in the air that we cannot see with the naked eye. Apart from some natural microorganisms, there are also a large number of pathogenic bacteria, fungi, viruses and mycoplasma. In particular, some infectious pathogens such as the new type of coronavirus can exist in the form of aerosols and spread with the air flow, which can easily cause human-to-human infection. In public places such as hospitals, office buildings, shopping malls, etc., the use of central air-conditioning increases the incidence of infection. Although turning off the air-conditioning and ventilation system will reduce the air flow, the virus that continues to spread into the air can still be affected by the micro-airflow indoors. It will not solve the problem of virus transmissio...

AI Technical Summary

Problems solved by technology

However, due to the consideration of the overall load of the application, to meet the "fresh air volume" requirements, it will consume a lot of energy to turn on the fresh air. Therefore, the existing air conditioning systems are based on part of the fresh air, which makes the air exchange Inefficient, it is difficult to really effectively reduce the concentration of viruses and / or bacteria in the air

[0004] In response to the above problems, in order to reduce the concentration of bacteria in the air, there are currently disinfection and purification facilities designed for central air-conditioning systems on the market, including air disinfection and purification devices such as ultraviolet, ozone, classic, and plasma types, but these products basically use It is a single technology, the level of modularization and centralization is low, the efficiency of disinfection is not high, and it is inconvenient to disassemble and move the equipment
