Even, it exports final value by control flow.
Beneficial effects of the present invention:
The present invention can allow the service condition of user's real-time awareness filter core, and user is facilitated to replace filter core in time.The present invention was both
People's breathing can be allowed to fresh, clean air, also avoided because replacement filter core is too early and the problem of cost of idleness.The prison of offer
The method for surveying filter element life is accurate, and simple easily implementation.
Specific embodiment
Whether filter core needs replacing the amount for the dirty polluter that see that it is collected, and the dust suction amount of filter core is specified, filter core
The substance of collection reaches a certain amount of and needs replacing, and therefore, the substance to collect from it is monitored to the use state of filter core
Set about.I.e. when the material mass that filter core is collected can determine whether that filter core needs replacing to certain value.
New blower used in us is mounted on interior, and the pollutant that filter core is collected is mainly derived from defeated from outdoor air inlet
The air inclusion that enters and from the dust in the air that indoor air inlet inputs.So to calculate the matter that filter core collects pollutant
Amount need to calculate the quality of the outdoor air inlet pollutant of filter core collection and the summation of indoor air inlet pollutant quality.
The present invention is monitored method to filter element life specifically:
Monitoring modular is set in new wind devices, and note has filter core adsorbance predetermined value n in monitoring modular；Monitoring modular is read
