As shown in Figure 1, the embodiment realizes that the method for inletting fresh air control includes the following steps：
Step 11：When fresh air system is standby, every the control air quality sensor work of standby dwell time, run duration
For standby working time.
Fresh air system is standby, usually indoors air quality preferably, without inletting fresh air when fresh air system a kind of state.
Fresh air system still powers in this state, but the wind turbine of fresh air system is stopped.It is right when fresh air system is in holding state
Air quality sensor makees following control：
Every the control air quality sensor work of standby dwell time, run duration is standby working time.
Specifically, in standby dwell time, control air quality sensor stops acquisition air quality data；It is treating
In the machine working time, control air quality sensor gathers real-time air quality data.That is, when fresh air system is standby, it is empty
Makings quantity sensor not works always, but is interrupted sex work.Standby dwell time of anticipating as the off-air time, with standby
Working time as the working time, realizes interruption sex work, is generally powered off within the off-air time, to stop gathering air
Qualitative data normally powers in standby working time, can gather real-time empty makings according to the sample frequency of sensor in itself
Measure data.
Wherein, air quality sensor can be the sensor that fresh air system carries, for example carried for fresh air system, use
In the PM2.M sensors of detection indoor accelerated test concentration or carry for fresh air system, for detecting indoor dense carbon dioxide
Gas concentration lwevel sensor of degree, etc..In addition, air quality sensor can also be independently of fresh air system but remain to

Interior air quality sensor or to be installed on the air quality sensor in air conditioner.The embodiment passes air quality
The assembling structure of sensor and fresh air system is simultaneously not construed as limiting.
Step 12：The real-time air quality data that air quality sensor gathers in standby working time is obtained, according to
Real-time air quality data control fresh air system is standby or starts.
Fresh air system keeps holding state still to be switched to start working condition by holding state, is sensed still according to air quality
The real-time air quality data of device acquisition is determined, also, is gathered with air quality sensor in standby working time
Real-time control qualitative data determine.In standby working time, air quality sensor according to sensor itself sampling
Frequency, it may be possible to collect multiple air quality datas.So, the multiple air quality datas that will be gathered in standby working time
It is averaged, using average value as the data for determining fresh air system working condition.
Specifically, the value of real-time air quality data can be made comparisons with the first given threshold.If real-time air
The value of qualitative data is not less than the first given threshold, shows that indoor air quality is deteriorated, it is necessary to which inletting fresh air, then control fresh air system
Start.Otherwise, if the value of air quality data is less than the first given threshold in real time, show that indoor air quality is preferable, without
Inletting fresh air then controls fresh air system to keep holding state.Wherein, the first given threshold is known, reflection indoor air quality
A reference value.
In the inletting fresh air control realized using the process of above-described embodiment, when fresh air system is standby, air quality sensing
Device is not constantly in working condition, but works again after certain standby dwell time, thus, it is standby in fresh air system
In the case of, the working time of air quality sensor is shortened, and then the normal use of air quality sensor can be extended
Time solves frequent or frequent shadow is replaced because caused by expiring air quality sensor service life to a certain extent
The problem of ringing fresh air system normal operation.Moreover, under fresh air system holding state, air quality is generally more excellent, passes through
Rationally determine suitable standby dwell time, will not cause because in standby dwell time air quality sensor do not work, nothing
Method starts fresh air system and influences the normal adjustment to air quality.
Wherein, standby dwell time and standby working time are known.And, it is preferred that standby dwell time is more than
Standby working time that is, the time that air quality sensor is stopped is longer, within a work period, stops
The time of work is longer, to be reduced as far as the waste to the invalid usage time of air quality sensor.For example, it is standby
Dwell time is 10min, standby working time 5min.So, when fresh air system is standby, air quality sensor every
10min continuous firing 5min, and determine whether fresh air system needs to open with the continuous firing 5min air quality datas gathered
It is dynamic to carry out inletting fresh air.
Fig. 2 is referred to, which show the flow chart based on another embodiment of inletting fresh air control method of the present invention.
As shown in Fig. 2, the embodiment realizes that the method for inletting fresh air control includes the following steps：

System starts the real-time air quality data that air quality sensor is gathered in the course of work and is adjusted, and meets：Such as fruit
When air quality data value it is big or in real time air quality data value belonging to codomain it is big, then, start dwell time
It is worth small.Specifically, if the value of air quality data or affiliated codomain are big, show air quality difference, it is necessary to air matter
Amount work is rapider, tracks in time, then adjusts the time for starting that dwell time is small, and reduction air quality sensor is stopped.
Moreover, the value for starting dwell time is not more than the value of standby dwell time, so that in the hollow makings of the fresh air system course of work
There is quantity sensor more frequent data acquisition to act, and is further ensured that and air quality is made to track more rapidly, in time.
Startup dwell time is specifically adjusted using the value or affiliated codomain of real-time air quality data, according to pre-
The correspondence of the value of first definite air quality data and the value of startup dwell time determines.Preferably,
In order to simplify determination process, the codomain of multiple air quality datas is previously provided with, when each codomain corresponds to a startup stopping
Between, and codomain is bigger, and it is smaller to start dwell time.So, in fresh air system start-up course, it is first determined real-time air quality
Then codomain belonging to the value of data determines to start dwell time according to codomain, then, according to starting dwell time and known
Start working time control air quality sensor interruption sex work, acquisition air quality data.
Preferably, after real-time air quality data is got, first by the value of real-time air quality data
