Description

A kind of computational methods for changing air purifier filter screen
Technical field
The present invention relates to a kind of air purifier, particularly a kind of computational methods for changing air purifier filter screen.
Background technology
The filter screen laying dust of air purifier reaches is accomplished by replacing in time to a certain degree, and current air purifier can show Show the residual life time of filter screen, when calculating the residual life time, the reality of machine is subtracted from the schedule operating time of filter screen Working time, that is, it is considered as the residual life time of filter screen, due in the filter screen laying dust degree and environmental quality of air purifier Grain thing concentration, the wind speed of blower fan, the working time of machine etc. are relevant, it is obvious that when current computational methods only considered work Between, do not account for influenceing the other factors of filter screen service life, cause filter screen to be also not reaching to actual life and just done sth. in advance Replacing causes to waste, or has reached actual life in advance without being changed in time, influences the clean-up effect of air.
The content of the invention
In order to overcome the deficiencies in the prior art, present invention offer is a kind of to be capable of more ventilating for closer filter screen actual life The computational methods of clarifier filter screen.
The technical solution adopted for the present invention to solve the technical problems is：
A kind of computational methods for changing air purifier filter screen, this method pre-establishes the corresponding wind speed COEFFICIENT Ks of wind speed VVTable and The corresponding concentration factor K of particle concentration NNTable, with wind speed COEFFICIENT KVOr concentration factor KNChange turns to an operation interval, calculates Operation interval dust containing capacity QiAnd filter screen aggregate value method of weighting dust quantity Q∑i, the laying dust amount Q of filter screen point is changed according to setting and filter screen adds up laying dust Measure Q∑iDifference, calculate current operating state lower filter screen residual life TM, calculation formula is：
TM=（Q-Q∑i）/（KV* S* KN）；
Dust containing capacity Qi=KV* S* Ti*KN；
S is screen area；
TiFor the time of i-th of operation interval.
The beneficial effects of the invention are as follows：The present invention is changed using the wind speed through filter screen, particle concentration and the time is foundation, The real work life-span of filter screen is calculated, result of calculation is more nearly the actual life of filter screen, more science, accurate.
Embodiment
A kind of computational methods for changing air purifier filter screen, this method pre-establishes the corresponding wind speed COEFFICIENT Ks of wind speed VV Table and the corresponding concentration factor K of particle concentration NNTable, with wind speed COEFFICIENT KVOr concentration factor KNChange turns to an operation interval, Evaluation work interval dust containing capacity QiAnd filter screen aggregate value method of weighting dust quantity Q∑i, the laying dust amount Q of filter screen point is changed according to setting and filter screen adds up Laying dust amount Q∑iDifference, calculate current operating state lower filter screen residual life TM, calculation formula is：
TM=（Q-Q∑i）/（KV* S* KN）（1）；
Dust containing capacity Qi=KV* S* Ti*KN （2）；
S is screen area；
TiFor the time of i-th of operation interval.
Air purifier has multiple gears, and the corresponding rotation speed of fan of gear is fixed, that is, is passed through under different gears The wind speed V of filter screen is also relatively-stationary（Ignore the change of Air permenbility before and after filter screen laying dust）, the wind speed can be according to blower fan Power and vapor permeation area, which are calculated, to be obtained, and can also be surveyed and be obtained, that is, the corresponding wind speed V of gear is known, is by control System reads the gear of blower fan, it is possible to determine wind speed COEFFICIENT KV, such as at one grade, wind speed coefficient is KV1, such as at two grades, wind speed Coefficient is KV2, three times when the wind speed of two grades of time is one grade, then it is considered that corresponding KV2=3*KV1.Filter screen point is changed in setting Laying dust amount Q can be surveyed in laboratory and pass through formula（2）Calculating is obtained, and Air permenbility, filter effect etc. can not be met normally Laying dust amount Q during work is the laying dust amount Q that filter screen point is changed in setting, the screen material and area of a type be it is fixed, The laying dust amount Q for changing filter screen point is also fixed.
Particle concentration N is obtained by the sensor measurement of air purifier, and particle concentration N change is more frequent, is The workload calculated is reduced, the present invention establishes the corresponding concentration factor K of particle concentration N in a programNTable, such as：Particle N is in N for thing concentration1- N2In the range of when, concentration factor is KN1, particle concentration N is in N3- N4In the range of when, concentration factor is KN2, such as 1 ＜（N3- N4/N1- N2）When≤1.5, then KN2=1.5* KN1。
Once KVOr KNChange, current operation interval just terminates, start simultaneously at another operation interval, control System passes through formula（2）Calculate the dust containing capacity Q of an operation intervali, and added up with dust containing capacity before, pass through formula（1） Calculate the interval corresponding residual life T of work at presentMTime, and be shown on the display screen of machine, in residual life TMExpire Afterwards, machine alarm or display failure, remind user change filter screen, use with through filter screen wind speed, particle concentration change and Time is foundation, calculates the real work life-span of filter screen, and result of calculation is more nearly the actual life of filter screen, more science, standard Really.
