S101. Obtain the operating status of the air treatment equipment;

S102: When the air processing equipment is in a closed state, determine the air intake volume entering the room within a set time;

S103: Control the opening angle of the window according to the air inlet volume.

The embodiments of the present disclosure can automatically open windows according to the state of the air treatment equipment, and ensure the quality of indoor air by controlling the opening angle of the windows, thereby bringing a more comfortable experience to users.

As shown in Figure 2, in some embodiments, it includes:

S201. Obtain the operating status of the air treatment equipment;

S202: When the air processing equipment is in a closed state, determine the amount of air entering the room within a set time and detect the outdoor wind speed;

S203. Determine the opening angle of the window according to the outdoor wind speed and the air intake volume, and open the window according to the angle;

S204. Control the opening time of the window according to the outdoor wind speed and outdoor air volume.

Optionally, the air treatment equipment is an air conditioner, of course, it may also be an air purification equipment or the like. After the air conditioner or air purification equipment is turned off, if the windows are not opened in time, the indoor air quality will gradually decline, so it is necessary to open the windows in time for ventilation. For a period of time after the air handling equipment is closed, indoor air may be better than outdoor air. Therefore, in some embodiments, after the air handling equipment is turned off, it waits for a set interval, and then determines the opening angle of the window according to the outdoor wind speed. Open the window, by controlling the motor or other window opening driving device to perform corresponding actions, and then controlling the opening angle and opening time of the window.

In some embodiments, determining the amount of air entering the room within a set time includes:

Obtain the indoor temperature through the temperature sensor; match the corresponding preset air intake volume according to the indoor temperature. For example, when the indoor temperature is detected to be 25°C, as shown in Table 1, the corresponding air intake within 0.5 hours is 20CFM; when the indoor temperature is detected as 28°C, the corresponding air intake within 0.5 hours is set It is 35CFM; when the indoor temperature is detected as 30℃, the corresponding air intake within 0.5 hours is set to 60CFM.

set time	Room temperature	Air intake
0.5h	25℃	20CFM
0.5h	28°C	35CFM
0.5h	30℃	60CFM

Table 1 Correspondence table between indoor temperature and air intake within set time

In some embodiments, as shown in Table 2, the corresponding preset opening angle can be matched according to the air intake volume. For example, when the matched air inlet volume is 20CFM, the corresponding opening angle is 15°, and the motor operation is controlled according to the preset opening angle to control the opening angle of the window.

Air intake	Opening angle
20CFM	15°
35CFM	32°
60CFM	47°

Table 2 Correspondence between air intake and opening angle

In some embodiments, determining the opening angle of the window according to outdoor wind speed and air intake includes:

Calculate the outdoor air volume within the set time according to the outdoor wind speed; when the outdoor air volume is not less than the inlet air volume, determine the window opening angle according to the outdoor air volume; when the outdoor air volume is less than the inlet air volume, the window opening angle is the predicted Set angle. Optionally, the outdoor wind speed V is measured by the wind speed sensor, and the outdoor wind direction is detected by the wind vane. Calculation

Obtain the outdoor air volume, where S is the cross-sectional area of the window, α is the resistance coefficient, β is the tailwind coefficient, and θ _v is the wind vane angle value, 0<α<1, 0<β<1. The wind speed and direction outside the windows are monitored by installing wind speed sensors and wind vanes outdoors. When θ _v ＞90°, the outdoor wind direction is greatly affected by the windows, and the windows block the outdoor wind, and the outdoor wind needs to bypass the open windows. Then enter the room, and when 0°≤θ _v ≤90°, the outdoor wind enters the room directly from the opening of the window or changes the angle of entering the room with the help of the window. According to the above method, it can be more in line with the actual situation according to different wind directions. Get the outdoor air volume to more accurately determine the opening angle of the window.

Calculation

Obtain the angle value θ, and use θ as the opening angle of the window; where T is the set time, a is the width of the window, h is the height of the window, L is the outdoor air volume, V is the outdoor wind speed, and t is the set time compensation value ; V, t, T, a and h are all greater than 0. By compensating for the preset air intake time, the air intake volume is guaranteed. On this basis, the outdoor air volume outside the window can be used to obtain the window opening angle obtained by the above algorithm, which can guarantee the indoor and outdoor air within the set time to a greater extent. The exchange effect provides a reference for the balance point of indoor and outdoor air exchange, which makes the control of windows more intelligent and precise, and at the same time reduces the degree of action of various driving mechanisms such as motors to a certain extent, and correspondingly reduces The wear and energy consumption of various driving mechanisms are reduced.

In some embodiments, the method further includes: rounding the angle value θ, and using the rounded angle value θ as the opening angle of the window; and rounding the angle value θ to retain the angle value The integer part of θ.

In some embodiments, controlling the opening time of the window according to outdoor wind speed and outdoor air volume includes:

In the case of constant outdoor wind speed, the opening time of the window is

When the outdoor wind speed increases, the opening time of the window is

In the case of reduced outdoor wind speed, the opening time of the window is

After the time is over, send a control command to the drive mechanism such as the motor to close the window.

a is the width of the window, h is the height of the window, L is the outdoor air volume, V is the outdoor wind speed, V, a and h are all greater than 0, θ≠0; t'is the set time correction value, t'>0. According to the change of outdoor wind speed, the opening time of the windows is dynamically adjusted, which can better maintain the balance of interaction between the indoor environment and the outdoor environment, and can ensure the efficiency of indoor and outdoor air exchange.
