The invention relates to the field of efficient
fresh air filtering for automobile air conditioners and discloses an efficient
fresh air filtering method and
system for an automobile air conditioner. The method and
system can be used for efficiently filtering out fine particular matters and harmful matters from
fresh air for an automobile. The method is characterized in that after foul air is efficiently filtered through an
air filter which is connected with an air conditioner fresh air filtering
system shell in a sealed manner via an efficient sealing device and a double efficient sealing device, clean air is fed into the automobile. Meanwhile, a turbulence
equalizer is used, so that the filtering effect on
ultrafine particle matters is improved; by detecting the difference of air pressures at the front end and the rear end of the
air filter, the work state of a draught fan is controlled, the
air volume is enabled to be constant, and the replacement of the
air filter is promoted; and an intelligent harmful gas and substance
detector detects the quality of air in the automobile, and the work state of the fresh air system can be automatically controlled. The efficient fresh air filtering method and system for the automobile air conditioner have the following remarkable advantages that no extra space in the automobile is occupied; the safety is achieved, and the attractiveness is not affected; secondary
pollution of
ozone is not generated; the service life of a filter screen is long; and the efficient fresh air filtering method and system for the automobile air conditioner are suitable for fresh
air filtration of automobile air conditioners of any type.
