Study on effect of wet on dust collection of central air conditioning

  Objective   During the spreading of respiratory epidemic, to change all-air central air conditioning system in order to clean dust and sterilize air, and to reduce the second pollution and cut off the way of spreading virus.

  Methods   Standing on the dust removing, the wet filler is used to be the function part of dust collection and sterilization.

  Results   The wet dust collection with filler can usually remove the 25-40 percent of dust with a diameter of 1 micron, and 75-98 percent of 5 micron, but the pressure loss is 30-130 pascal.

  Conclusions   The wet dust collection with filler can clean, sterilize, humidify and cool the air.It can replace the first dust collection in the traditional air conditioning, and it is important to stop the virsus spreading by the system, improve the air quality and save the energy.
