[0026] The following is combined Figures 1-3 The present invention describes an air conditioner control method, apparatus, and storage medium.

[0027] like Figure 1 As shown, an embodiment of the present invention provides an air conditioner control method, including: step 100, obtaining the current indoor temperature of the room where the air conditioner is located and the set temperature of the air conditioner, and determining the temperature difference between the current indoor temperature and the set temperature, wherein the temperature difference is greater than or equal to 0; step 200, adjusting the operating frequency of the compressor based on the relationship between the temperature difference and the preset temperature difference.

[0028] Step 100: In either cooling or heating mode, obtain the current indoor temperature of the room where the air conditioner is located as Tr, the set temperature of the air conditioner as Ts, and the temperature difference between the current indoor temperature and the set temperature as Ts-Tr≥0, or Tr-Ts≥0. It can be understood that in heating mode, the air conditioner's set temperature is lower than the current indoor temperature. In heating mode, the air conditioner's set temperature is higher than the current indoor temperature.

[0029] In step 200, the running frequency of the compressor is adjusted based on the relationship between the temperature difference and the preset temperature difference. During the running of the air conditioner, the current indoor environment temperature gradually increases or decreases to approach the set temperature of the user. In the case that the current indoor environment temperature approaches or meets the set temperature, the running frequency of the compressor can be adjusted based on the relationship between the current indoor environment temperature and the preset temperature, so as to meet the target temperature set by the user, avoid frequent start and stop, protect the compressor, and prolong the service life of the compressor.

[0030] The air conditioner control method provided by the embodiment of the application adjusts the running frequency of the compressor based on the relationship between the temperature difference between the current indoor temperature and the set temperature and the preset temperature difference, reduces the start and stop of the compressor, ensures the reliability of the compressor itself, prolongs the service life, reduces the indoor temperature fluctuation, and improves the user comfort.

[0031] In step 200, the running frequency of the compressor is adjusted based on the relationship between the temperature difference and the preset temperature difference, including: in the case that the temperature difference is greater than the first preset temperature difference, the compressor is controlled to run at the first frequency; in the case that the temperature difference is greater than the second preset temperature difference and less than or equal to the first preset temperature difference, the compressor is controlled to run at the second frequency; the second frequency is less than the first frequency; in the case that the temperature difference is greater than the third preset temperature difference and less than or equal to the second preset temperature difference, the compressor is controlled to run at the third frequency; the third frequency is less than the second frequency; in the case that the temperature difference is greater than the fourth preset temperature difference and less than or equal to the third preset temperature difference, the compressor is controlled to run at the fourth frequency; the fourth frequency is less than the third frequency; in the case that the temperature difference is greater than the fifth preset temperature difference and less than or equal to the fourth preset temperature, the compressor is controlled to run at the fifth frequency; the fifth frequency is less than the fourth frequency.

[0032] The maximum frequency f max of the compressor is the minimum frequency f min of the compressor, and the difference f max between the maximum frequency and the minimum frequency of the compressor. min is the first frequency difference.

[0033] In the cooling or heating mode, if the temperature difference between the current indoor temperature and the set temperature is Ts-Tr≥0, and Ts-Tr> the first preset temperature difference, the temperature difference between the current indoor environment temperature and the set temperature is large, and the running frequency of the compressor is controlled to run at the first frequency f1, which can be the maximum frequency f max of the compressor, i.e., f1=f max , so that the current indoor environment temperature quickly reaches the set temperature and meets the user demand.

[0034] In the case of the first preset temperature difference > Ts-Tr > the second preset temperature difference, the temperature difference between the current indoor environment temperature and the set temperature is reduced, the running frequency of the compressor is reduced to the second frequency f2, wherein the second frequency f2 is less than the first frequency f1, such as the second frequency being the sum of 3 / 4 of the first frequency difference and the minimum frequency of compression, i.e., f2 = f min + 3 / 4 (f max -f min ).

[0035] In the case of the second preset temperature difference > Ts-Tr > the third preset temperature difference, the temperature difference between the current indoor environment temperature and the set temperature is reduced again, the running frequency of the compressor is reduced to the third frequency f3, wherein the third frequency f3 is less than the third frequency f2, such as the third frequency being the sum of 1 / 2 of the first frequency difference and the minimum frequency of compression, i.e., f3 = f min + 1 / 2 (f max -f min ).

[0036] In the case of the third preset temperature difference > Ts-Tr > the fourth preset temperature difference, the temperature difference between the current indoor environment temperature and the set temperature is reduced again, the running frequency of the compressor is reduced to the fourth frequency f4, wherein the third frequency f4 is less than the third frequency f3, such as the fourth frequency being the sum of 1 / 4 of the first frequency difference and the minimum frequency of compression, i.e., f4 = f min + 1 / 4 (f max -f min ).

[0037] In the case of the fourth preset temperature difference > Ts-Tr > the fifth preset temperature difference, the running frequency of the compressor is reduced again to the fifth frequency f5, wherein the fifth frequency f5 is less than the fourth frequency f4, such as the fifth frequency being the minimum frequency of compression, i.e., f5 = f min .

[0038] The air conditioner control method provided by the embodiment of the application can increase the running frequency of the compressor when the temperature difference between the current indoor temperature and the set temperature is large, so as to accelerate the increase or decrease of the current indoor environment temperature and meet the comfort requirement of the user; and can reduce the running frequency of the compressor when the temperature difference is small, so as to reduce the increase or decrease speed of the current indoor environment temperature and reduce the start-stop frequency of the compressor.

[0039] For example Figure 2As shown, the air conditioner control method provided by the embodiment of the present application further comprises: step 300, acquiring the current frequency of the compressor and the minimum frequency of the compressor, and determining a second frequency difference between the current frequency of the compressor and the minimum frequency of the compressor; and step 400, in the case where the temperature difference is greater than a sixth preset temperature difference, adjusting the operating frequency of the compressor based on the relationship between the second frequency difference and a preset frequency difference.

[0040] Specifically, in the case where the second frequency difference is greater than a first preset frequency difference, the operating frequency of the compressor is controlled to be reduced to a sixth frequency f6, where f6 can be f min + the second preset frequency difference, for example, if the second frequency difference is 40, i.e., f6=f min + 40.

[0041] In the case where the second frequency difference is greater than a second preset frequency difference and less than or equal to the first preset frequency difference, the operating frequency of the compressor is controlled to be reduced again to a seventh frequency f7; the seventh frequency f7 is less than the sixth frequency f6; f7 can be f min + a third preset frequency difference, for example, if the third frequency difference is 20, i.e., f7=f min + 20.

[0042] In the case where the second frequency difference is less than or equal to the second preset frequency difference, the operating frequency of the compressor is controlled to be reduced again to an eighth frequency f8, where the eighth frequency f8 is less than the seventh frequency f7; f8 can be f min .

[0043] After the first time interval, the current indoor environment temperature is acquired again, the temperature difference between the current indoor environment temperature and the set temperature is determined; in the case where the temperature difference is less than or equal to the sixth preset temperature difference, the compressor is controlled to operate at the current frequency; and in the case where the temperature difference is greater than the sixth preset temperature difference, the operating frequency of the compressor is adjusted.

[0044] Specifically, in the case where the second frequency difference is greater than the first preset frequency difference, the operating frequency of the compressor is controlled to be reduced to a ninth frequency f9, where the ninth frequency f9 is less than the sixth frequency f6 and less than or equal to the seventh frequency f7, for example, f9=f min + 20.

[0045] In the case where the second frequency difference is greater than the second preset frequency difference and less than or equal to the first preset frequency difference, the operating frequency of the compressor is controlled to be reduced to a tenth frequency f 10 , where the tenth frequency f 10 is less than the seventh frequency f7 and less than or equal to the eighth frequency f8; for example, f 10 =f min .

[0046] In the case where the second frequency difference is less than or equal to the second preset frequency difference, the compressor is controlled to operate at the minimum frequency fmin The second preset time length is 1 minute.

[0047] Based on the above embodiment, in the refrigeration mode, in the process of adjusting the frequency of the compressor, when the current indoor environment temperature is greater than the set temperature, the compressor is controlled to run at the initial frequency, the frequency adjustment is stopped, the current indoor temperature is lowered, and the user comfort is met.

[0048] In the heating mode, in the process of adjusting the frequency of the compressor, when the current indoor environment temperature is lower than the set temperature, the compressor is controlled to run at the initial frequency, the frequency adjustment is stopped, the current indoor temperature is raised, and the user comfort is met.
