[0028] As described in the background section, existing solutions for regulating the air conditioner compressor simply compare the indoor temperature with the set temperature and adjust the compressor frequency accordingly, either by significantly increasing or decreasing it. While this can quickly bring the indoor temperature close to the set temperature, such large adjustments result in high energy consumption, thus increasing the operating costs of the air conditioner.

[0032] This embodiment provides a method for controlling an air conditioner that runs on a mobile terminal, computer terminal, or similar computing device. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Also, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0033] Figure 2This is a schematic flowchart illustrating an air conditioner control method according to an embodiment of this application. Figure 2 As shown, the method includes the following steps:

[0034] Step S201: Obtain the temperature of the indoor environment where the air conditioner is located at the current moment, the temperature of the wall of the indoor environment at the current moment, and the temperature set by the air conditioner at the current moment, and obtain the current inner ring temperature, the current wall temperature, and the current set temperature respectively.

[0035] Specifically, by simultaneously considering both the temperature of the indoor environment where the air conditioner is located at the current moment and the temperature of the walls in the indoor environment at the same current moment, the accuracy of the compressor adjustment of the air conditioner can be ensured during subsequent judgments.

[0036] After step S201, that is, after obtaining the temperature of the indoor environment where the air conditioner is located at the current moment, the temperature of the wall in the indoor environment at the current moment, and the temperature set by the air conditioner at the current moment, and obtaining the current inner loop temperature, the current wall temperature, and the current set temperature respectively, the above method further includes:

[0037] If the difference between the current inner ring temperature and the current wall temperature is positive, it is determined that the frequency of the air conditioner compressor needs to be increased.

[0038] If the difference between the current inner ring temperature and the current wall temperature is positive, it means that the air conditioner is not able to provide a comfortable environment for the user and the compressor frequency needs to be increased to quickly provide a comfortable environment for the user.

[0039] Based on the difference between the current inner ring temperature and the current wall temperature and the frequency boost mapping relationship, the target frequency boost amount is determined. The frequency boost mapping relationship is the mapping relationship between the difference between the current inner ring temperature and the current wall temperature and the frequency boost amount. The target frequency boost amount is the frequency boost amount corresponding to the difference between the current inner ring temperature and the current wall temperature.

[0040] By establishing a mapping relationship between the difference between the current inner ring temperature and the current wall temperature and the frequency increase, it is easier to find the corresponding frequency increase based on the difference between the current inner ring temperature and the current wall temperature. This makes the adjustment of the compressor more precise and significantly reduces energy consumption compared to existing solutions.

[0041] The frequency of the compressor of the air conditioner is adjusted to the sum of the compressor's frequency at the current moment and the target frequency increase.

[0042] For example, if the compressor's frequency at the current moment is A and the target frequency increase is B, then the frequency of the compressor in the air conditioner will be adjusted to A+B.

[0043] If the difference between the current inner ring temperature and the current wall temperature is negative, it is determined that the frequency of the air conditioner compressor needs to be reduced.

[0044] Specifically, if the difference between the current inner ring temperature and the current wall temperature is negative, it means that the air conditioner has already provided a comfortable environment for the user, and the compressor frequency needs to be reduced to save energy.

[0045] Based on the difference between the current inner ring temperature and the current wall temperature and the frequency reduction mapping relationship, the target frequency reduction amount is determined. The frequency reduction mapping relationship is the mapping relationship between the difference between the current inner ring temperature and the current wall temperature and the frequency reduction amount. The target frequency reduction amount is the frequency reduction amount corresponding to the difference between the current inner ring temperature and the current wall temperature.

[0046] By establishing a mapping relationship between the difference between the current inner ring temperature and the current wall temperature and the frequency reduction, it becomes easier to find the corresponding frequency reduction based on the difference between the current inner ring temperature and the current wall temperature. This makes the adjustment of the compressor more precise and significantly reduces energy consumption compared to existing solutions.

[0047] The frequency of the compressor of the air conditioner is adjusted to the difference between the compressor's frequency at the current moment and the target frequency reduction amount.

[0048] For example, if the compressor frequency at the current moment is A and the target frequency reduction is C, then the frequency of the compressor in the air conditioner will be adjusted to A-C.

[0049] Step S202: Determine a reference temperature corresponding to the current inner ring temperature and the current wall temperature, at least based on the range of the absolute value of the difference between the current inner ring temperature and the current wall temperature; and determine whether to increase or decrease the frequency of the air conditioner compressor based on the sign of the difference between the current set temperature and the reference temperature.

[0050] Specifically, the compressor frequency is adjusted based on the sign of the difference between the current set temperature and the reference temperature, which can quickly provide a comfortable environment for the user and save energy for the air conditioner while the user is in a comfortable environment.

[0051] Specifically, determining the reference temperature corresponding to the current inner ring temperature and the current wall temperature is based at least on the range of the absolute value of the difference between the current inner ring temperature and the current wall temperature. There are two ways to achieve this:

[0052] The first implementation method (without considering the suitable temperature for the human body):

[0053] If the absolute value of the difference between the current inner ring temperature and the current wall temperature is less than a first temperature threshold, the reference temperature is determined to be the average of the current inner ring temperature and the current wall temperature; if the absolute value of the difference between the current inner ring temperature and the current wall temperature is greater than or equal to the first temperature threshold, the maximum value of the current inner ring temperature and the current wall temperature is determined.

[0054] Specifically, the first temperature threshold can be 4℃. The reference temperature represents the correction value of the indoor detected dry-bulb temperature, which is close to the human body's sensing temperature. The reference temperature is slightly lower than the room air temperature, so it can achieve energy-saving effects when used in calculations. The values ​​will vary slightly depending on the compressor. Each letter can be assigned the same value, but not necessarily an equal increment. For example, if the compressor frequency is 50Hz, and the difference between the current inner ring temperature and the current wall temperature is 2℃, the compressor's additional value is 'a'. At this time, the compressor frequency is adjusted to (50+a)Hz. After the frequency is increased, the overall cooling output of the unit increases, and if it remains within the stable range, the compressor will maintain the increased frequency.

[0055] The second implementation method (considering the suitable temperature for the human body):

[0056] If the absolute value of the difference between the current inner ring temperature and the current wall temperature is less than the first temperature threshold, and the current inner ring temperature is within the preset temperature range, the reference temperature is determined to be the average value of the current inner ring temperature and the current wall temperature.

[0057] If the absolute value of the difference between the current inner ring temperature and the current wall temperature is greater than or equal to the first temperature threshold, and / or the current inner ring temperature is within the preset temperature range, the maximum value of the current inner ring temperature and the current wall temperature is determined.

[0058] Specifically, by simultaneously considering the absolute value of the difference between the current inner ring temperature and the current wall temperature, as well as whether the current inner ring temperature is within the preset temperature range, the reference temperature determined subsequently can be close to the human body sensing temperature. That is, the subsequent adjustment frequency can be adjusted in a direction that makes the user feel comfortable. The preset temperature range is [20℃, 26℃].

[0059] Step S202, determining whether to increase or decrease the frequency of the air conditioner compressor based on the sign of the difference between the current set temperature and the reference temperature, includes: determining that the frequency of the air conditioner compressor needs to be increased when the difference between the current set temperature and the reference temperature is positive; and determining that the frequency of the air conditioner compressor needs to be decreased when the difference between the current set temperature and the reference temperature is negative.

[0060] Step S203: If it is determined that the frequency of the air conditioner compressor needs to be increased, determine the frequency increase amount corresponding to the difference between the current set temperature and the reference temperature, and adjust the frequency of the air conditioner compressor using the frequency increase amount.

[0061] Step S203, namely determining the frequency increase corresponding to the difference between the current set temperature and the reference temperature, and adjusting the frequency of the air conditioner compressor using the frequency increase, includes: determining a target frequency increase based on the difference between the current set temperature and the reference temperature and a frequency increase mapping relationship, wherein the frequency increase mapping relationship is a mapping relationship between the difference between the current set temperature and the reference temperature and the frequency increase, and the target frequency increase is the frequency increase corresponding to the difference between the current set temperature and the reference temperature; and adjusting the frequency of the air conditioner compressor to the sum of the compressor's frequency at the current moment and the target frequency increase.

[0062] Specifically, by setting the difference between the current set temperature and the aforementioned reference temperature, and establishing a frequency boost mapping relationship, the frequency boost amount corresponding to the difference between the current set temperature and the aforementioned reference temperature can be found from this mapping relationship, thereby improving the accuracy of the air conditioner compressor's frequency correction. The frequency determination can be slowly updated between 1 minute and 5 minutes during the air conditioner compressor's operating time at a certain frequency, or the frequency can be updated within 20 seconds.

[0063] Step S204: If it is determined that the frequency of the air conditioner compressor needs to be reduced, determine the frequency reduction amount corresponding to the difference between the current set temperature and the reference temperature, and adjust the frequency of the air conditioner compressor using the frequency reduction amount.

[0064] In the above steps, the temperature of the indoor environment where the air conditioner is located at the current moment, the temperature of the walls of the indoor environment at the current moment, and the temperature set by the air conditioner at the current moment are considered simultaneously to determine the reference temperature. The corresponding frequency is determined based on the difference between the set temperature and the reference temperature, which reduces the energy consumption of the air conditioner and allows the air conditioner to operate in a way that makes the user feel comfortable, thereby improving the user experience. This also solves the problem that the existing solution has poor frequency control efficiency of the air conditioner compressor, resulting in high energy consumption.

[0065] Step S204, namely determining the frequency reduction amount corresponding to the difference between the current set temperature and the reference temperature, and adjusting the frequency of the air conditioner's compressor using the frequency reduction amount, includes: determining a target frequency reduction amount based on the difference between the current set temperature and the reference temperature and a frequency reduction mapping relationship, wherein the frequency reduction mapping relationship is a mapping relationship between the difference between the current set temperature and the reference temperature and the frequency reduction amount, and the target frequency reduction amount is the frequency reduction amount corresponding to the difference between the current set temperature and the reference temperature in the frequency reduction mapping relationship; and adjusting the frequency of the air conditioner's compressor to the difference between the compressor's frequency at the current moment and the target frequency reduction amount.

[0066] Specifically, by setting a mapping relationship between the difference between the current set temperature and the reference temperature and the frequency reduction amount, the frequency reduction amount corresponding to the difference between the current set temperature and the reference temperature can be found from the mapping relationship in the future, thereby enabling the air conditioner to save energy without reducing user comfort.

[0067] To enable those skilled in the art to better understand the technical solution of this application, the implementation process of the air conditioner control method of this application will be described in detail below with reference to specific embodiments.

[0068] This embodiment relates to a specific air conditioner control method, such as... Figure 3 As shown, it includes the following steps:

[0069] Step S1: Obtain the temperature of the indoor environment where the air conditioner is located at the current moment, the temperature of the indoor wall at the current moment, and the temperature set by the air conditioner at the current moment, and obtain the current inner ring temperature, the current wall temperature, and the current set temperature respectively;

[0070] Step S2: If the absolute value of the difference between the current inner ring temperature and the current wall temperature is less than the first temperature threshold and the current inner ring temperature is within the preset temperature range, determine the reference temperature as the average value of the current inner ring temperature and the current wall temperature; if the absolute value of the difference between the current inner ring temperature and the current wall temperature is greater than or equal to the first temperature threshold, and / or the current inner ring temperature is within the preset temperature range, determine the maximum value between the current inner ring temperature and the current wall temperature.

[0071] Step S3: If the difference between the current set temperature and the reference temperature is positive, determine that the frequency of the air conditioner compressor needs to be increased; if the difference between the current set temperature and the reference temperature is negative, determine that the frequency of the air conditioner compressor needs to be decreased.

[0072] Step S4: If it is determined that the frequency of the air conditioner compressor needs to be increased, determine the target frequency increase amount based on the difference between the current set temperature and the reference temperature and the frequency increase mapping relationship. The frequency increase mapping relationship is the mapping relationship between the difference between the current set temperature and the reference temperature and the frequency increase amount. The target frequency increase amount is the frequency increase amount corresponding to the difference between the current set temperature and the reference temperature. Adjust the frequency of the air conditioner compressor to the sum of the compressor's frequency at the current moment and the target frequency increase amount.

[0073] Step S5: If it is determined that the frequency of the air conditioner compressor needs to be reduced, determine the target frequency reduction amount based on the difference between the current set temperature and the reference temperature and the frequency reduction mapping relationship. The frequency reduction mapping relationship is the mapping relationship between the difference between the current set temperature and the reference temperature and the frequency reduction amount. The target frequency reduction amount is the frequency reduction amount corresponding to the difference between the current set temperature and the reference temperature in the frequency reduction mapping relationship. Adjust the frequency of the air conditioner compressor to the difference between the compressor's frequency at the current moment and the target frequency reduction amount.

[0074] It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases the steps shown or described may be executed in a different order than that shown here.
