The air conditioner has various work functions including: cooling, heating or purification, etc. In the embodiment of the invention, two or more air conditioners are included in a sealed space, the purification module in each air conditioner not only operates independently, but also can perform purification operation cooperatively, namely the controller can determine the first air conditioner corresponding to the maximum fine particle concentration value according to the fine particle concentration PM.5 value corresponding to each air conditioner, and determine the operation modes of the first air conditioner and other air conditioners according to the concentration value difference between the maximum fine particle concentration value and the average fine particle concentration value of other air conditioners, so that the purification module of each air conditioner or the operation of the purification module and a fan are cooperatively controlled, thereby ensuring the maximum purification effect of PM2.5, improving the overall utilization rate of the purification module, simultaneously quickly reducing the PM2.5 value in the space and improving the air quality in the space.
FIG. 1 is an architectural diagram illustrating an air purification system according to an exemplary embodiment. As shown in fig. 1, the air purification system includes: a controller 100, and two or more air conditioners 200 carrying air cleaning modules in the same enclosed space.
In a home where a user is located, there may be a plurality of rooms each of which is equipped with an air conditioner 200 carrying an air purification module, and each of the rooms may be individually sealed, or a window of each of the rooms is closed but a door of each of the rooms is opened, so that all the air conditioners may be located in the same sealed space. Alternatively, the work area where the user is located may be the same enclosed space including two or more air conditioners 200 carrying the air purification modules. In addition, in this embodiment, the air conditioner may be a "one-drive-multiple" air conditioner, that is, one air conditioner indoor unit is configured in each room, and two or more air conditioner indoor units may share one outdoor unit.
The controller 100 may communicate with each air conditioner 200, such that the controller 100 is configured to obtain a concentration value of the fine particles detected by each air conditioner 200, determine an air conditioner corresponding to a maximum concentration value of the fine particles as a first air conditioner, determine other air conditioners as second air conditioners, and obtain an average concentration value of the fine particles corresponding to the second air conditioner and a concentration value difference between the maximum concentration value of the fine particles and the average concentration value of the fine particles; determining the operation mode of each air conditioner corresponding to the concentration value difference value, and sending a cooperative purification instruction carrying the corresponding operation mode to each air conditioner 200;
and the air conditioner 200 is configured to control the operation of the purification module, or the purification module and the fan, according to the operation mode received in the cooperative purification instruction.
In the embodiment of the present invention, each air conditioner 200 may detect the fine particle concentration PM2.5 value in the action area, so that the controller 100 may obtain each PM2.5 value, and then perform comparison to determine the air conditioner corresponding to the maximum PM2.5 value a as the first air conditioner. The other air conditioners except the first air conditioner are determined as the second air conditioner. The detected PM2.5 values of each second air conditioner are b1, b2 and … bn respectively, wherein n is the number of the second air conditioners and can be one, two or more. Accordingly, the average PM2.5 value bp ═ (b1+ b2+ … + bn)/n for the second air conditioner can be obtained. In this way, the difference in concentration value between the maximum PM2.5 value and the average PM2.5 value, X, is obtained as a-bp. The controller can determine the operation mode of each air conditioner according to the concentration value difference value X, and then respectively sends a cooperative purification instruction carrying the corresponding operation mode to the corresponding air conditioner, namely, the cooperative operation process of the purification module in the air conditioner is started.
The first correspondence between the concentration value range and the operation mode may be previously stored, and thus, the operation mode of each air conditioner corresponding to the obtained concentration difference value X may be determined according to the stored first correspondence.
Table 1 shows a first correspondence between a range of concentration values and an operating mode according to an exemplary embodiment.
Range of concentration values First air conditioner operation mode Second air conditioner operation mode
X is less than the first set value First mode of operation First mode of operation
X is not less than the first set value and not more than the second set value First mode of operation Second mode of operation
Second set value < X First mode of operation Third mode of operation
TABLE 1
As shown in table 1, the second set point is greater than the first set point, for example: the first set value is 100, the second set value is 700, or the first set value is 80 and the second set value is 600, or the first set value is 60, the second set value is 650, etc., preferably the first set value is a value less than or equal to 100, and the second set value is a value greater than 500, for example.
If the obtained concentration value difference value X is smaller than a first set value, the difference of PM2.5 values in the whole closed space is not large, so that each air conditioner can operate in the same operation mode, namely the first operation mode is adopted, and each air conditioner performs purification operation. If the difference value X of the concentration value obtained is smaller than or equal to the first set value and smaller than or equal to the second set value, the PM2.5 value of the area where the first air conditioner is located is larger, so that the first air conditioner continues to operate in the first operation mode, and the air conditioners in other areas, namely the second air conditioner, can operate in the second operation mode to assist in purification. And if the second set value is less than the acquired concentration value difference value X, the PM2.5 value of the area where the first air conditioner is located is very large, the air pollution is serious, the first air conditioner can mainly perform purification operation before the pollution is diffused, namely the operation mode of the first air conditioner is still the first operation mode, and the second air conditioner can adopt the third operation mode, namely the second air conditioner can stop operating the purification module.
As can be seen, according to table 1, the controller may determine an operation mode of each air conditioner, and then, send a cooperative purification instruction carrying the corresponding operation mode to each air conditioner, thereby starting the cooperative operation of the purification module.
The controller communicates with the air conditioners, obtains the concentration value of the fine particulate matters detected by each air conditioner, and then determines the first air conditioner, and the process of the second air conditioner can be started according to a user instruction, or is performed periodically, for example: and every 20 minutes or 30 minutes, the controller acquires the concentration value of the fine particulate matters detected by each air conditioner, then determines a first air conditioner and a second air conditioner, and sends corresponding cooperative purification instructions carrying the working modes.
After the air conditioner receives the cooperative purification instruction, the purification module can be controlled according to the operation mode carried in the cooperative purification instruction, or the operation of the purification module and the fan.
When the air conditioner receives a cooperative purification instruction carrying a first operation mode, the purification module can be started all the time, namely, the purification module is started to operate, the current fine particle concentration value is obtained through periodic sampling, and then the air speed of the fan is controlled according to the obtained current fine particle concentration value. And when the air conditioner receives the cooperative purification instruction of the second operation mode, the air conditioner can control the purification module to be turned on or off and the air speed of the fan according to the acquired current fine particle concentration value and the current humidity value. And when the air conditioner receives the cooperative purification instruction of the third operation mode, the purification module can be closed.
Therefore, in the embodiment of the present invention, the controller 100 is specifically configured to send a cooperative purification instruction carrying the first operation mode to each air conditioner 200 when the concentration value difference is smaller than the first set value; when the concentration value difference is greater than or equal to a first set value and less than or equal to a second set value, sending a cooperative purification instruction carrying a first operation mode to the first air conditioner, and sending a cooperative purification instruction carrying a second operation mode to each second air conditioner; and when the concentration value difference is greater than a second set value, sending a cooperative purification instruction carrying a first operation mode to the first air conditioner, and sending a cooperative purification instruction carrying a third operation mode to each second air conditioner, wherein the second set value is greater than the first set value.
The air conditioner 200 is specifically configured to, when receiving a cooperative purification instruction carrying a first operation mode, start a purification module to operate, and control the air speed of the fan according to a current fine particle concentration value obtained by periodic sampling; when a cooperative purification instruction carrying a second operation mode is received, controlling the purification module to be turned off and on and controlling the wind speed of the fan according to the acquired current fine particle concentration value and the current humidity value; and when receiving the cooperative purification instruction carrying the third operation mode, closing the purification module.
When the air conditioner operates in the first operation mode, the purification module is always started to operate, and the air speed of the fan can be controlled according to the current fine particle concentration value obtained by periodic sampling. And the process of controlling the wind speed of the wind turbine according to the current fine particle concentration value obtained by periodic sampling can include various processes, such as: and pre-storing a corresponding relation between the PM2.5 value and the wind speed, directly determining the current wind speed corresponding to the current fine particle concentration value according to the corresponding relation, and then controlling the fan according to the current wind speed. Or, the current fine particle concentration value is the current fine particle concentration value obtained by first adoption, and the current fan speed corresponding to the current fine particle concentration value is determined according to the corresponding relation between the saved fine particle concentration value range value and the fan speed; and if the current fine particle concentration value and the previous fine particle concentration value obtained by the previous sampling are not in the same range value in the corresponding relationship, determining the wind speed of the fan adjacent to the wind speed of the previous fan in the corresponding relationship as the current fan wind speed according to a set rule, and controlling the fan to operate at the current fan wind speed. Therefore, the fan is adjusted more slowly, cannot be suddenly high or suddenly low, and the fan is further protected.
In this way, in the air purification system, the air conditioner 200 is specifically configured to, after receiving the cooperative purification instruction carrying the first operation mode, determine, according to a correspondence between a range value of the stored fine particle concentration value and the fan wind speed, a current fan wind speed corresponding to the current fine particle concentration value if the current fine particle concentration value is the current fine particle concentration value acquired by the first adoption; and if the current fine particle concentration value and the previous fine particle concentration value obtained by the previous sampling are not in the same range value in the corresponding relationship, determining the wind speed of the fan adjacent to the wind speed of the previous fan in the corresponding relationship as the current fan wind speed according to a set rule, and controlling the fan to operate at the current fan wind speed.

If the current fine particle concentration value is the current fine particle concentration value obtained by first adoption, namely the initial PM2.5 value, and if the initial PM2.5 value is 800 and is larger than 700, the current wind speed of the fan can be determined to be the wind speed of the powerful wind of the air conditioner according to the corresponding relation shown in the figure 2. The obtained current fine particle concentration value is not the initial PM2.5 value, at this time, if the PM2.5 value is 750, and still belongs to the range value larger than 700 according to the corresponding relationship shown in fig. 2, the current fan speed is kept at the wind speed of the air-conditioning strong wind, if the PM2.5 value is 450, and when the previous fine particle concentration value 800 obtained by the previous sampling is not at the same range value in the corresponding relationship shown in fig. 2, at this time, according to a preset rule that the two sides are close to the center, the high wind adjacent to the previous fan speed, that is, the strong wind, can be determined as the current fan speed, and thus, the fan can be controlled to operate at the wind speed of high wind. If the current fine particle concentration value is the current fine particle concentration value obtained by first adoption, namely the initial PM2.5 value, and if the initial PM2.5 value is 50 and is smaller than 100, the current wind speed of the fan can be determined to be the mute wind speed of the air conditioner according to the corresponding relation shown in the figure 2. At the set sampling time, the newly acquired current fine particle concentration value is not the initial PM2.5 value, at this time, if the PM2.5 value is 80, according to the corresponding relationship shown in fig. 2, still belongs to a range value smaller than 100, the current fan wind speed is kept at the air conditioner mute level wind speed, if the PM2.5 value is 250, and when the previous fine particle concentration value 50 acquired by the previous sampling is not within the same range value in the corresponding relationship shown in fig. 2, at this time, according to a preset center-to-side diffusion rule, the low wind adjacent to the previous fan wind speed, that is, the mute level wind speed, can be determined as the current fan wind speed, and thus, the fan can be controlled to operate at the wind blocking speed of low wind. Of course, the previous PM2.5 value is between 100 and 700, and the current wind speed of the fan corresponding to the current PM2.5 value may be determined according to the above rule, or the current wind speed of the fan corresponding to the current PM2.5 value may be directly determined according to the corresponding relationship shown in fig. 2, which is not specifically exemplified.

If the obtained current PM2.5 value is 600 mu g/m3When the current humidity value is 40 RH%, it may be determined that the current humidity value corresponds to a region one in fig. 3, and thus, the purge module is activated to control the fan to operate at the minimum gear wind speed. If the obtained current PM2.5 value is 600 mu g/m3When the current humidity value is 60 RH%, it may be determined to correspond to the region two in fig. 3, and thus, the purge module is turned off and the fan is controlled to operate at the set wind speed, for example, the medium wind speed. If the obtained current PM2.5 value is 200 mu g/m3When the current humidity value is 35 RH%, it may be determined that the current humidity value corresponds to the third area in fig. 3, so that the purification module is started, and the fan is controlled to operate at the set wind speed; if the obtained current PM2.5 value is 200 μ g/m3When the current humidity value is 55 RH%, it may be determined that the current humidity value corresponds to the area four in fig. 3, and thus, the purge module is started to control the fan to operate at the minimum gear wind speed.
Of course, the division of the regions of the PM2.5 value and the humidity value in the embodiment of the present invention is not limited to this, and other setting range values may be used, which is not limited to this.

step 401: and obtaining the concentration value of the fine particles detected by each air conditioner, determining the air conditioner corresponding to the maximum concentration value of the fine particles as a first air conditioner, and determining other air conditioners as second air conditioners.
The controller can communicate with each air conditioner to obtain the concentration value of the fine particles detected by each air conditioner, and then the air conditioner corresponding to the maximum concentration value of the fine particles is determined as a first air conditioner, and other air conditioners are determined as second air conditioners.
Step 402: an average fine particle concentration value corresponding to the second air conditioner and a concentration value difference between the maximum fine particle concentration value and the average fine particle concentration value are obtained.
The detected PM2.5 values of each second air conditioner are b1, b2 and … bn respectively, wherein n is the number of the second air conditioners and can be one, two or more. Accordingly, the average PM2.5 value bp ═ (b1+ b2+ … + bn)/n for the second air conditioner can be obtained.

Preferably, the sending of the cooperative purification instruction carrying the corresponding operation mode to each air conditioner includes: when the concentration value difference value is smaller than a first set value, sending a cooperative purification instruction carrying a first operation mode to each air conditioner, enabling the air conditioners to start a purification module to operate when receiving the cooperative purification instruction carrying the first operation mode, and controlling the air speed of a fan according to the current fine particle concentration value obtained by periodic sampling; when the concentration value difference value is greater than or equal to a first set value and less than or equal to a second set value, sending a cooperative purification instruction carrying a first operation mode to the first air conditioner, and sending a cooperative purification instruction carrying a second operation mode to each second air conditioner, so that when the first air conditioner receives the cooperative purification instruction carrying the first operation mode, the first air conditioner starts the purification module to operate, and controls the air speed of the fan according to the current fine particle concentration value obtained by periodic sampling, and when the second air conditioner receives the cooperative purification instruction carrying the second operation mode, the second air conditioner controls the purification module to turn off and the air speed of the fan according to the obtained current fine particle concentration value and the obtained current humidity value; when the concentration value difference value is larger than a second set value, sending a cooperative purification instruction carrying a first operation mode to the first air conditioner, and sending a cooperative purification instruction carrying a third operation mode to each second air conditioner, so that when the first air conditioner receives the cooperative purification instruction carrying the first operation mode, the first air conditioner starts a purification module to operate, controls the air speed of a fan according to the current fine particle concentration value obtained by periodic sampling, and when the second air conditioner receives the cooperative purification instruction carrying the third operation mode, the second air conditioner closes the purification module; wherein the second set value is greater than the first set value.
As shown in table 1, if the difference X between the obtained concentration values is smaller than or equal to the first set value and smaller than or equal to the second set value, the PM2.5 value of the area where the first air conditioner is located is larger, so that the first air conditioner continues to operate in the first operation mode, and the air conditioners in other areas, that is, the second air conditioner, may operate in the second operation mode to assist in purification, so that the cooperative purification instruction carrying the first operation mode may be sent to the first air conditioner, and the cooperative purification instruction carrying the second operation mode may be sent to the second air conditioner. Therefore, after the first air conditioner receives the cooperative purification instruction carrying the first operation mode, the purification module is started to operate, and the air speed of the fan is controlled according to the current fine particle concentration value obtained by periodic sampling. And after each second air conditioner receives the cooperative purification instruction carrying the second operation mode, the purification module is controlled to be turned off and on and the wind speed of the fan is controlled according to the acquired current fine particle concentration value and the current humidity value.

Also, the controller controls the cooperative purifying operation of the air conditioner and may also terminate the cooperative purifying operation of the air conditioner, and therefore, the method further includes: and when a cooperative purification stopping instruction sent by the controller is received, stopping the running cooperative purification mode. Of course, if other control instructions which are all manual are received in the process of the cooperative purification operation under each air conditioner, the cooperative purification operation can also be stopped.
