Under the condition that the current rotating speed of the inner fan is in a low wind gear, the rotating speed of the inner fan can be adjusted to a medium wind gear; under the condition that the current rotating speed of the inner fan is the middle wind gear, the rotating speed of the inner fan can be adjusted to the high wind gear. Under the condition that the current rotating speed of the outer fan is in a low wind gear, the current rotating speed of the inner fan can be adjusted to be in a medium wind gear; under the condition that the rotating speed of the outer fan is in the middle wind gear, the current rotating speed of the outer fan can be adjusted to the high wind gear. The rotating speed of the fan (inner fan or outer fan) corresponding to the low wind gear is less than that of the fan corresponding to the medium wind gear, the rotating speed of the fan corresponding to the medium wind gear is less than that of the fan corresponding to the high wind gear, the specific rotating speeds of the low wind gear, the medium wind gear and the high wind gear are related to the specific model of the inner fan or the outer fan, and the rotating speed of the inner fan can be different from that of the outer fan under the same gear.
Through the technical scheme, the temperature adjusting capacity of the air conditioner to the first air supply area can be improved from the first temperature adjusting capacity to the second temperature adjusting capacity.
Optionally, increasing the current frequency of the compressor by the set frequency to obtain a new frequency of the compressor, including: obtaining a current outdoor environment temperature; obtaining a maximum target frequency of the compressor corresponding to a current outdoor ambient temperature; and under the condition that the current frequency of the compressor is the maximum target frequency, increasing the set frequency on the basis of the current frequency of the compressor, and obtaining a new frequency of the compressor.
In practical applications, the operating frequency of the compressor is not usually set too high, for example, the maximum target frequency is set, and the frequency of the compressor is not usually allowed to exceed the maximum target frequency in the process of controlling the compressor, so as to protect the compressor.
In the application scenario for realizing global constant temperature provided in the embodiment of the present disclosure, since the local indoor temperature is too high (in the cooling process, if the temperature difference between the average temperature value corresponding to the first air supply region and the set temperature is greater than or equal to the first set temperature difference, it is determined that the temperature of the first air supply region is "too high") or too low (in the heating process, if the temperature difference between the set temperature and the average temperature value corresponding to the first air supply region is greater than or equal to the first set temperature difference, it is determined that the temperature of the first air supply region is "too low"), which may result in reducing the user comfort level, and even if the current frequency of the compressor is the maximum target frequency, the set frequency is increased based on the current frequency of the compressor, so as to further increase the temperature regulation capability of the air conditioner on the first air supply region, and to quickly realize the balance of the global indoor temperature.
Of course, the set frequency should not be too high, and if the set frequency is too high, the compressor will be damaged, and the service life of the compressor will be reduced. The set frequency may be 1Hz or 2Hz.
The second set temperature difference may represent an adjustment dead zone, that is, in a case where a temperature difference between the first temperature average of the first air supply region and the set temperature is less than or equal to the second set temperature difference, it is determined that the first temperature average of the first air supply region satisfies a condition of global constant temperature, and the second set temperature difference may be, for example, 1 ℃. Therefore, the phenomenon that the air conditioner repeatedly adjusts the first air supply area after the first temperature average value approaches the set temperature can be avoided.
Further, the second set temperature difference is larger than the temperature of the prior art regulation dead zone, which is used to indicate the temperature of the lead stop regulation, for example, the prior art regulation dead zone may be 1 ℃, and the second set temperature difference may be 2 ℃ or 3 ℃. That is, when the temperature difference between the first temperature average of the first air blowing zone and the set temperature is less than or equal to the second set temperature difference (the second set temperature difference is greater than the temperature of the regulation dead zone), it is determined that the first temperature average of the first air blowing zone satisfies the condition of the global constant temperature.
When the temperature difference between the first temperature average of the first air supply area and the set temperature is smaller than or equal to the second set temperature difference, the air supply direction of the air conditioner needs to be moved from the first air supply area to other air supply areas, or the temperature adjusting capacity of the air conditioner needs to be reduced from the second temperature adjusting capacity to the first temperature adjusting capacity, before the air supply direction of the air conditioner is moved from the first air supply area to other air supply areas, or the temperature adjusting capacity of the air conditioner is reduced from the second temperature adjusting capacity to the first temperature adjusting capacity, the air conditioner still adjusts the first temperature average of the first air supply area, for example, the air outlet temperature of the air conditioner is still larger than the first temperature average of the first air supply area in the heating process, or the air outlet temperature of the air conditioner is still smaller than the first temperature average of the first air supply area in the cooling process, therefore, the air conditioner still enables the first temperature average of the first constant temperature area to approach the set temperature, therefore, when the temperature difference between the first temperature average of the first air supply area and the set temperature is smaller than or equal to the second set temperature difference, the first temperature average of the first air supply area is determined, on the one hand, the air conditioner can reduce the energy consumption of the first air supply area, and on the whole area, and on the other hand, the air conditioner can reduce the air supply area.
In addition, if the following is used when adjusting the frequency of the compressor: on the basis of the maximum target power of the compressor corresponding to the current outdoor environment temperature, the frequency of the compressor is continuously increased to the set frequency, at the moment, the first temperature average value represents the advance stop adjustment, the time length of the compressor running at the maximum target frequency larger than the current outdoor environment temperature can be reduced, and the risk of damage to the compressor is reduced.
In the case where the temperature of the lead-stop adjustment is represented by the second set temperature difference, the second set temperature difference is positively correlated with the capacity of the air conditioner. After a controller of the air conditioner determines that a first temperature average value of a first air supply area meets the condition of global constant temperature (the temperature difference between the first temperature average value and a set temperature is smaller than or equal to a second set temperature difference), in the process that the air conditioner reduces the frequency of a compressor, or in the process that the air conditioner reduces the rotating speed of an inner fan or the rotating speed of an outer fan, or in the process that the air conditioner transfers the air supply direction from the first air supply area to other air supply areas, the larger the capacity of the air conditioner is, the larger the influence of the air conditioner on the first temperature average value of the first air supply area is, at the moment, a larger second set temperature difference can be set, so that the first temperature average value of the first air supply area more accurately approaches the set temperature, the time length for the air conditioner to adjust the first air supply area is shortened, the time length for the compressor to operate at the maximum target frequency corresponding to the current outdoor environment is shortened, and the risk of damage of the compressor is reduced.
The second set temperature difference is inversely related to the volume of the first air supply area, in a scene that a plurality of preset areas exist in the indoor space, the volume of the first air supply area can be represented by the number of the preset areas contained in the first air supply area, and if the number of the preset areas contained in the first air supply area is more, the second set temperature difference is smaller; the second set temperature difference is larger if the number of preset areas included in the first blowing area is smaller.
After the controller of the air conditioner determines that the first temperature average value of the first air supply area meets the condition of global constant temperature (the temperature difference between the first temperature average value and the set temperature is smaller than or equal to a second set temperature difference), in the process that the air conditioner reduces the frequency of the compressor, or in the process that the air conditioner reduces the rotating speed of the inner fan or the rotating speed of the outer fan, or in the process that the air conditioner transfers the air supply direction from the first air supply area to other air supply areas, the larger the volume of the first air supply area is, the smaller the influence of the air conditioner on the first temperature average value of the first air supply area is, and at the moment, a smaller second set temperature difference can be set so that the first temperature average value of the first air supply area can reach the set temperature more accurately.
Optionally, the temperature difference between the first temperature average value and the set temperature of the first air supply area is smaller than or equal to a second set temperature difference, and the method includes: and within the set time length, the temperature difference between the first temperature average value of the first air supply area and the set temperature is continuously smaller than or equal to the second set temperature difference.
The set time period here may be 10s, 15s, 20s or longer. And starting timing when the temperature difference between the first temperature average value and the set temperature is detected to be switched to be less than or equal to a second set temperature difference from being greater than the second set temperature difference, and resetting the recorded time length if the temperature difference between the first temperature average value and the set temperature of the first air supply area is switched to be greater than the second set temperature difference from being less than or equal to the second set temperature difference within the set time length.
The air supply area comprises a plurality of preset areas, the temperature average value corresponding to the air supply area can reflect the ambient temperatures of the preset areas in the air supply area on the whole, the ambient temperatures of the preset areas in the air supply area can reach the set temperature on the whole quickly according to the temperature average value corresponding to the air supply area and the first temperature average value of the first air supply area with larger set temperature adjusting temperature difference, and then the global constant temperature is finally realized quickly based on the heat conduction and air convection effect.

In order to improve the temperature adjusting capacity of the air conditioner to the first air supply area and quickly realize the balance of the indoor global temperature, the frequency of the compressor can be continuously improved by a set frequency on the basis of the maximum target frequency corresponding to the current outdoor environment temperature, and before that, the current exhaust protection temperature of the compressor is compensated to improve the exhaust protection temperature of the compressor, so that the phenomenon of shutdown protection of the compressor is avoided in the process of continuously improving the frequency of the compressor by the set frequency on the basis of the maximum target frequency corresponding to the current outdoor environment temperature.
