step S10, the air conditioner detects the number of human bodies in the indoor environment in real time or at regular time through a camera;
in this embodiment, referring to fig. 3, the air conditioner of the present invention includes an indoor unit 1, a fresh air duct 5, a fresh air blower 4, a camera 2, and a controller 3, wherein the fresh air blower 4 is disposed in the fresh air duct 5, the fresh air duct 5 is connected to an indoor side and an outdoor side to introduce external fresh air, and the fresh air duct 5 and the fresh air blower 4 are a part of the structure of the air conditioner in this embodiment, in other embodiments, the air conditioner may be an independent device independent of the air conditioner, specifically, when the fresh air duct 5 and the fresh air blower 4 are independent devices, the independent device has a controller disposed in the fresh air duct to receive a carbon dioxide concentration in an indoor environment and determine a rotation speed of the fresh air blower according to the carbon dioxide concentration; the camera 2 is arranged at the indoor unit to detect the number of human bodies in the indoor environment in real time or at regular time, and in other embodiments, other devices with cameras can send the collected number of human bodies to the air conditioner. When the camera 2 detects the number of the human bodies at regular time, cyclic detection can be performed in a period of 3min, and signals are fed back to the controller. The execution main body of the invention can be an air conditioner or a server.
In the embodiment, the technical scheme that the number of human bodies in the indoor environment is detected in real time or at regular time and the rotating speed of the fresh air fan is determined according to the number of the human bodies is adopted, so that the concentration of carbon dioxide in the indoor environment can be kept in a stable low-concentration state, even if an air conditioner is started, the concentration of carbon dioxide in the indoor environment is higher, and after the scheme provided by the invention is operated for a period of time, the concentration of carbon dioxide in the indoor environment can be kept in a low-concentration state, so that the freshness of air in the indoor environment is ensured.
Of course, in other embodiments, the number of human bodies may be obtained by a device with a human body number detection function, and the obtained number of human bodies may be detected and sent to an air conditioner or a server.
Step S20, determining the rotating speed of the fresh air fan according to the number of the human bodies;
in this embodiment, when the number of human bodies in the indoor environment is obtained, the rotation speed of the fresh air fan corresponding to the number of human bodies may be obtained through table lookup or calculation, and the rotation speed may include a rotation speed gear or a specific rotation speed value.
Specifically, with reference to Table one,
Figure GDA0002687482560000061
watch 1
According to the human body quantity, look-up a table to obtain the rotating speed gears of the fresh air fan corresponding to the human body quantity, for example:
when no human body exists in the indoor environment, namely N is 0, looking up a table to obtain that the rotating speed gear of the fresh air fan corresponding to the human body number N is zero, namely controlling the fresh air fan to be in a closed state;
when N is 1, looking up a table to obtain that the rotating speed gear of the fresh air fan corresponding to the human body number N is 1;
when N is 2, looking up a table to obtain that the rotating speed gear of the fresh air fan corresponding to the human body number N is 2;
when N is 3, looking up a table to obtain that the rotating speed gear of the fresh air fan corresponding to the human body number N is 3;
when N is 4, looking up a table to obtain that the rotating speed gear of the fresh air fan corresponding to the human body number N is 4;
and when N is 5, looking up a table to obtain that the rotating speed gear of the fresh air fan corresponding to the human body number N is 5.
It can be understood that the interval of the number of the human bodies can be divided into 6 interval ranges, and reasonable thinning and increasing can be carried out according to actual needs, so that the operation of the fan is more refined, the requirements of different users are met, and the comfort is further improved.
Specifically, with reference to Table II,
Figure GDA0002687482560000071
watch two
According to the human body number, the rotating speed value of the fresh air fan corresponding to the human body number is obtained by looking up a table, for example:
when no human body exists in the indoor environment, namely N is equal to 0, the rotating speed value of the fresh air fan corresponding to the number N of the human bodies is zero by looking up a table, namely the fresh air fan is controlled to be in a closed state right 4;
when N is 1, looking up a table to obtain that the rotating speed value of the fresh air fan corresponding to the human body number N is 100rpm (Revolutions Per Minute);
when N is 2, looking up a table to obtain that the rotating speed value of the fresh air fan corresponding to the human body number N is 200 rpm;
when N is 3, looking up a table to obtain that the rotating speed value of the fresh air fan corresponding to the human body number N is 300 rpm;
when N is 4, looking up a table to obtain that the rotating speed value of the fresh air fan corresponding to the human body number N is 400 rpm;
and when N is 5, looking up a table to obtain that the rotating speed value of the fresh air fan corresponding to the number N of the human bodies is 500 rpm.
It can be understood that the interval of the number of the human bodies can be divided into 6 interval ranges, and reasonable thinning and increasing can be carried out according to actual needs, so that the operation of the fan is more refined, the requirements of different users are met, and the comfort is further improved.
In another embodiment, the rotation speed value of the fresh air fan corresponding to the number of human bodies can be obtained by formula calculation according to the number of human bodies, for example:
the rotating speed value M of the fresh air fan is 100N, wherein the range of N is more than 0 and less than or equal to 5; when N > 5, M is 500.
When no human body exists in the indoor environment, namely N is equal to 0, setting the rotating speed value of the fresh air fan to be zero, namely controlling the fresh air fan to be in a closed state;
and when N is more than 0 and less than or equal to 5, calculating the rotating speed value of the fresh air fan corresponding to the human body number N according to the formula.
And step S30, controlling the fresh air fan to operate according to the rotating speed.
In this embodiment, when the number of the human bodies is zero, the fresh air fan is controlled to be turned off; when the number of the human bodies is larger than the preset number, controlling the fresh air fan to operate at the maximum rotating speed; and when the number of the human bodies is larger than zero and smaller than the preset number, controlling the fresh air fan to operate at a rotating speed corresponding to the concentration interval range where the number of the human bodies is located. Specifically, when the number of the human bodies is between zero and the preset number, and the rotating speed gear or the rotating speed value of the fresh air fan corresponding to the range of the human bodies is obtained through table lookup, the fresh air fan is controlled to operate at the corresponding rotating speed gear or the corresponding rotating speed value.
According to the fresh air exchange control method of the air conditioner, the number of human bodies in an indoor environment is detected in real time or at regular time through the air conditioner through the camera, then the rotating speed of the fresh air fan is determined according to the number of the human bodies, and then the fresh air fan is controlled to operate according to the rotating speed. Thus, the fluctuation of the carbon dioxide concentration in the room can be avoided to be large, and the freshness of the indoor air is stabilized. Furthermore, the rotating speed of the fresh air fan is adjusted according to the number of human bodies in the current indoor environment, so that noise caused by the fact that the fresh air fan is always in a high-speed running state can be avoided.
Referring to fig. 4, in the second embodiment, based on the embodiment shown in fig. 2, the step S10 is further followed by:
step S40, when the number of the human bodies reaches the critical number, the concentration of the carbon dioxide in the indoor environment is obtained;
in this embodiment, the critical number may be set to 3 persons, and of course, the specific number may be set reasonably according to the size of the indoor room area. When the indoor room area is large, the critical number can be correspondingly increased; when the indoor room area is small, the critical number may be reduced accordingly.
The air conditioner is also provided with a carbon dioxide sensor arranged at the air return inlet of the indoor unit so as to detect the concentration of carbon dioxide in the indoor environment in real time or at regular time. When the carbon dioxide sensor detects the concentration of carbon dioxide regularly, the carbon dioxide sensor can perform cyclic detection in a period of 3min and feed back signals to the controller.
Step S50, determining the rotating speed of the fresh air fan according to the concentration of the carbon dioxide;
and step S60, controlling the fresh air fan to operate according to the rotating speed.
In this embodiment, if there is only one person in the current environment, the concentration of carbon dioxide generated is usually not high, and therefore, it is not necessary to detect the concentration of carbon dioxide in the indoor environment in real time or at regular time. When the number of the human bodies reaches 2 or more, the carbon dioxide concentration in the indoor environment rises faster, so that the carbon dioxide concentration in the indoor environment is detected when the number of the current human bodies reaches a critical number, and the fresh air fan is correspondingly controlled to operate according to the rotating speed according to the carbon dioxide concentration. Therefore, the carbon dioxide sensor does not need to be in a working state all the time, but is started to operate when the number of human bodies in the current indoor environment reaches a critical value, and therefore the service life of the carbon dioxide sensor can be prolonged.
Referring to fig. 5, in the third embodiment, based on the first embodiment or the second embodiment, the step S10 is further followed by:
step S40, determining the rotating speed of the fresh air fan and the opening of an air deflector of the air conditioner according to the number of the human bodies;
and S50, controlling the fresh air fan to operate according to the rotating speed, and controlling the air deflector to rotate to the opening degree.
In this embodiment, compared to the first embodiment, the opening degree of the air deflector of the air conditioner may also be determined according to the concentration of the carbon dioxide, and specific opening values are not described herein again. The determination principle of the opening value can be as follows: when the concentration of the carbon dioxide is higher or the rotating speed of the fresh air fan is higher, the opening degree of the corresponding air deflector is larger; when the concentration of the carbon dioxide is low or the rotating speed of the fresh air fan is low, the opening degree of the corresponding air deflector is small. Of course, in other embodiments, the determination principles set forth herein are not limited.
In the embodiment, the control on the opening degree of the air deflector is combined, so that when the concentration of carbon dioxide is higher, the air deflector is controlled to rotate to a larger opening degree, and the concentration of the carbon dioxide in the indoor environment can be reduced quickly; when carbon dioxide concentration is lower, the control aviation baffle is rotatory to less aperture, not only can avoid the noise that the new trend fan produced, can also avoid wind to blow directly to improve user experience.
The invention also provides an air conditioner, which comprises a processor, a memory and a fresh air change control program of the air conditioner, wherein the fresh air change control program of the air conditioner is stored on the memory and can run on the processor, and the steps of the fresh air change control method of the air conditioner in the embodiment are realized when the fresh air change control program of the air conditioner is executed by the processor.
The invention further provides a computer readable storage medium, wherein the computer readable storage medium stores a fresh air change control program of the air conditioner, and the fresh air change control program of the air conditioner realizes the steps of the fresh air change control method of the air conditioner according to the above embodiment when being executed by the processor.
