Specifically, the service life calculation of filter life:
It is calculated by taking high efficiency particle air filter as an example, the theoretical unit dust containing capacity for holding dirt entire life and filter paper of filter
And developed area is related, therefore the corresponding theoretical dust containing capacity of various filters is different, it is assumed that high efficiency particle air filter
The accumulation service life is A (it is assumed that 5000 hours)；
The variation of the wastage in bulk or weight speed of filter life CADR value/air quantity corresponding to each gear and PM2.5 numerical value is related,
Then:
The depletion rate of filter=CADR value coefficient * PM2.5 coefficient；
It is assumed that the indoor PM2.5 concentration detected at this time is 50 μ g/m when equipment operates in 160m3/h gear3(with every point
The average value of clock is calculated convenient for statistics as calculated value), then the CADR value/air volume coefficient set according to us is tabled look-up as 0.82
Obtain the coefficient of correspondence when PM2.5 concentration is 50 μ g/m3 are as follows: 0.00366*PM2.5 numerical value+0.58；Described table look-up is this
