Specific embodiment:
Embodiment one:
As shown in Figure 1:
In the initial state, natural wind draft fan is closed, air purifier is closed.
Then Outdoor Air Quality information is detected, Outdoor Air Quality index is obtained；Indoor air quality information is detected, is obtained
Take indoor air quality index；
Compare indoor and outdoors air index, first threshold, the size of second threshold；
There are several types of situations:
The first situation is that, when indoor air quality index is lower than first threshold, this first threshold, which represents, is suitble to people's life
Air quality index, should keep at this time, thus keep natural wind draft fan close, keep air purifier close.
Second situation is that, when indoor air quality index is higher than first threshold, indoor air quality is not achieved at this time
Standard, but Outdoor Air Quality index is lower than first threshold at this time, complies with standard.Therefore it is suitble to introduce outdoor air at this time
Interior, therefore natural wind draft fan is opened at this time, until indoor air quality index is consistent with Outdoor Air Quality index, so
Natural wind draft fan is closed afterwards.
