Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the enlarged drawing at A in Fig. 1.
Embodiment
Reference picture 1, Fig. 2, a kind of fresh air compensation are set with purifying two-in-one air purifier, including casing 1, the casing 1 Air inlet 2, fresh wind port 3 and air outlet 4 are equipped with, the fresh wind port 3 is connected to outdoor by airduct；Control is installed in the casing 1 Device processed and the blower fan electrically connected with the controller, the fan inlet of the blower fan are connected with the air inlet 2 and fresh wind port 3, The fan outlet of the blower fan is connected with the air outlet 4；Air channel area between the fresh wind port 3 and the fan inlet is small Air channel area between the air inlet 2 and the fan inlet；Filter screen and deep bead 5 are installed at the air inlet 2；Institute State deep bead and be connected with motor 6；The controller is connected with CO2Sensor, PM2.5 sensors, temperature sensor and humidity are passed Sensor.
Controller is realized that deep bead is opened or closed, kept out the wind according to the testing result of CO2 sensors, controlled motor action Plate is opened, and most air enter from air inlet, and a small amount of air enters from fresh wind port, is blown from the fan outlet of blower fan Go out, in purification mode of operation, after deep bead either on or off, after deep bead is closed, air inlet is plugged, outdoor air is from new Air port enters, and is blown out from the fan outlet of blower fan, in fresh air mode of operation, CO2 sensors can detect CO2 in room air The content of gas, when indoor CO2 gas contents exceed setting value, system automatically switches to fresh air mode of operation, toward interior Supplement fresh air, it can be ensured that IAQ, create good indoor environment.
The method of operation of the controller of the present invention using PM2.5 as condition:Work as PM2.5<75UG thinks that air quality is excellent, blower fan Low gear is run；As 75UG≤PM2.5<150UG thinks that air quality is good, and operation is kept off in blower fan；When PM2.5 >=150UG thinks empty Gas is of poor quality, blower fan top grade operation.
The method of operation of the controller of the present invention using CO2 as condition:Work as CO2<During 1000PPM, it is believed that air quality is excellent, wind Machine underdrive operating, is the purification mode of operation of interior circulation；As 1000PPM≤CO2<During 2000PPM, it is believed that air quality is general, Blower fan middle-grade is run, and is the fresh air mode of operation of outer circulation；As CO2 >=2000PPM, it is believed that air quality is severe, blower fan is high-grade Operation, is the fresh air mode of operation of outer circulation.
When PM2.5 has with CO2 conditions to conflict, controller preferentially performs the method for operation work using CO2 as condition, CO2<During 1000PPM, controller performs the method for operation work using PM2.5 as condition, is set when indoor CO2 gas contents exceed During definite value, system automatically switches to fresh air mode of operation, toward interior supplement fresh air, it can be ensured that IAQ, wound Make good indoor environment.
1 is provided with the display electrically connected with the controller, the display and shows filter on the casing of the present invention The residual life time T of netM, residual life time TMComputational methods be：Pre-establish the corresponding wind speed coefficients of wind speed V KVTable and the corresponding concentration factor K of particle concentration NNTable, with wind speed COEFFICIENT KVOr concentration factor KNChange turns to a workspace Between, 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 tires out Count 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 top grade, middle-grade, low grade, four units of sleep gear, the corresponding rotation speed of fan difference of four gears 1200r/min, 1000 r/min, 800 r/min, 600 r/min, due to the corresponding rotation speed of fan of gear be it is fixed, Wind speed V under exactly different gears through filter screen is also relatively-stationary（Ignore the change of Air permenbility before and after filter screen laying dust）, should Wind speed can be calculated according to the power and vapor permeation area of blower fan and obtained, and can also be surveyed and be obtained, that is, the corresponding wind speed V of gear It is known, the gear of blower fan is read by controller, 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.The laying dust amount Q that filter screen point is changed in setting can be surveyed in laboratory and be passed through formula（2）Calculating is obtained, Air permenbility, filtering effect Laying dust amount Q when fruit etc. can not meet normal work is the laying dust amount Q that filter screen point is changed in setting, the screen material of a type It is fixed with area, the laying dust amount Q for changing filter screen point is also fixed.
Particle concentration N is obtained by PM2.5 sensor measurements, and particle concentration N change is more frequent, in order to reduce meter The workload of calculation, the present invention establishes the corresponding concentration factor K of particle concentration N in a programNTable, such as：Particle concentration N exists N1- 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 Device 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）Meter Calculate the interval corresponding residual life T of work at presentMTime, and be shown on the display screen of machine, in residual life TMAfter expiring, Machine alarm or display failure, remind user to change filter screen, use with the wind speed through filter screen, particle concentration change and time For 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.
