Specific embodiment
The embodiment of the present invention is described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning to end
Same or similar label represents same or similar element or has the function of same or like element.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to for explaining the present invention, and is not considered as limiting the invention.
The air cleaning facility of the embodiment of the present invention and its strainer life estimation method, dress described below in conjunction with the accompanying drawings
It puts.
The air cleaning facility of the embodiment of the present invention can be that air purifier, air conditioner and fresh air system etc. include air
Strainer is purified, and passes through strainer and the equipment for realizing air purification is filtered to particulate solid and gaseous pollutant.
Fig. 1 is the flow chart according to the strainer life estimation method of the air cleaning facility of the embodiment of the present invention.
As shown in Figure 1, the strainer life estimation method of the air cleaning facility of the embodiment of the present invention, comprises the following steps：
S1, obtains the concentration for the target contaminant that strainer is filtered, and obtains the filter performance parameters of strainer and pass through filter
The filtering air quantity of net.
In one embodiment of the invention, can the dense of corresponding target contaminant be obtained by target contaminant sensor
Degree, such as the concentration of gaseous pollutant can be obtained by all kinds of gaseous pollutant sensors or passes through solid contaminant sensor
Obtain the concentration of solid contaminant.
In one embodiment of the invention, the filter performance parameters of strainer may include filter efficiency of strainer and ion
Release coefficient.
S2 tires out according to the concentration of target contaminant, the filter performance parameters of strainer and by the filtering Wind Coverage Calculation of strainer
Product purge amount.
In one embodiment of the invention, accumulation purge amount can be calculated according to the following formula：
Wherein, M is accumulation purge amount, and η (M) is filter efficiency of strainer, and ω (A) accounts for the hundred of total blast volume for filtering air quantity
Point ratio, λ be target contaminant concentration, A (ξ, α, κ) be total blast volume, and with rotation speed of fan ξ, the wind deflector of air cleaning facility
At least one parameter in angle [alpha], mode coefficient κ is related, and θ (t) is plasma diffusing W,Mo coefficient.
Wherein, the pollutant quality that purge amount adds up to intercept for strainer is accumulated.
Filter efficiency η (M) of strainer can be constant or the variable changed with the variation of accumulation purge amount.Filter
Filter efficiency η (M) of net can be determined by experiment and be stored in advance, to be called when calculating and accumulating purge amount.It lifts
For example, when filter efficiency η (M) of strainer is variable, filter efficiency η (M) of strainer can be obtained with tired by testing
The change curve for accumulating the variation of purge amount and changing, and store the change curve.
Plasma diffusing W,Mo coefficient θ (t) can be constant or variable.In air cleaning facility, for enhancing air purification effect
Fruit, the strainer of the embodiment of the present invention may include cation and anion release device or individual cation release device, bear from
Sub- release device.The plasma diffusing W,Mo coefficient θ (t) of plasma diffusing W,Mo device can be subject to ionic species and plasma diffusing W,Mo parameter, such as corona
The influence of voltage etc. in one embodiment of the invention, for every a kind of example release device, can obtain different ions in advance

The function of person, the two or three.Total blast volume A (ξ, α, κ) can be determined by experiment and be stored in advance, to calculate accumulation
It is called during purge amount.Wherein, mode coefficient κ represents that total blast volume generates when the different operational modes of air cleaning facility are to operation
Influence.For example, for air conditioner, under refrigeration, heating and air supply pattern, total blast volume is that different, different total blast volumes is
It can be reflected by mode coefficient κ.In one embodiment of the invention, if total blast volume A (ξ, α, κ) is rotation speed of fan ξ, wind-guiding
One in plate angle [alpha], mode coefficient κ three, both or three function, then can by test obtain total blast volume A (ξ, α, κ) with
One in rotation speed of fan ξ, wind deflector angle [alpha], mode coefficient κ three, both or three variation and the change curve that changes, and
Store the change curve.
The percentage ω (A) of total blast volume is accounted for for filtering air quantity, if all air-flows of air cleaning facility all flow process
Strainer is filtered, then ω (A)=1.But for some air cleaning facilities, and not all air-flow all flows through strainer, only part
Air-flow carries out purified treatment by strainer, therefore, can represent that filtering air quantity accounts for the ratio of total blast volume by ω (A).Wherein, should
Proportion omegab (A) may be related to total blast volume A, it is also possible to unrelated with total blast volume A.When ω (A) is related to total blast volume A, can pass through
Experiment obtains the relation curve of ω (A) and A, and stores the relation curve, to be called when calculating and accumulating purge amount.
It should be appreciated that filtering air quantity accounts for the product of the percentage ω (A) and total blast volume A (ξ, α, κ) of total blast volume, as pass through filter
The filtering air quantity of net.
S3 estimates the strainer service life according to accumulation purge amount.
In one embodiment of the invention, default purge amount can be preset, preset purge amount for the strainer service life just
Maximum purge amount during arrival, when accumulating purge amount less than the default purge amount, the air purification that still is able to meet of strainer will
Ask, when accumulating purge amount and being more than the default purge amount, strainer cannot effective filter solid particulate matter and gaseous pollutants, air
Clean-up effect is poor.
After accumulation purge amount is calculated, it can determine whether accumulation purge amount is more than or equal to default purge amount, if it is,
Judge that the strainer service life reaches, and air cleaning facility is controlled to send the prompt message for replacing strainer；If it is not, then it recalculates tired
Product purge amount.
After user replaces according to prompt message or cleans strainer, accumulation purge amount can be reset, and re-execute step
S1 to S3, to carry out life estimate to new strainer.
, can also be by accumulation purge amount compared with default purge amount after accumulation purge amount is calculated, and control air
Cleaning equipment shows comparative result.Specifically, it can show the percentage of accumulation purge amount and default purge amount, that is, show strainer
The percentage of service life alternatively, 1 percentage for subtracting accumulation purge amount and default purge amount can be shown, that is, shows that strainer remains
The percentage in remaining service life.Thereby, it is possible to user is made to know the strainer life status of air cleaning facility in real time.

Before purge amount, the main control unit of air cleaning facility can perform simultaneously or successively above-mentioned steps S101 to S105 with random order.
S107 by accumulation purge amount M compared with default purge amount M0, and shows comparative result.
S108 judges to accumulate whether purge amount M is more than default purge amount M0.If it is, step S109 is performed, if
No, then return to step S101 is to continue to build up.
S109 sends the prompt message for replacing strainer.Such as display or auditory tone cues can be sent.
S110, accumulation purge amount M are reset.After user replaces according to prompt message or cleans strainer, accumulation can be purified
M is measured to reset.Accumulation purge amount M shuts down after resetting, and return to step S101, to carry out life estimate to new strainer.
