[0002] In existing technology, the outdoor fan speed adjustment logic is based on the outer ring temperature and / or the compressor operating frequency. That is, for the first three minutes after the air conditioner is turned on, the outdoor fan speed is adjusted only based on the outer ring temperature.

[0047] Some embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0048] In the description of this invention, "module" and "processor" can include hardware, software, or a combination of both. A module may include hardware circuitry, various suitable sensors, communication ports, and memory, and may also include software components, such as program code, or a combination of software and hardware. A processor may be a central processing unit, microprocessor, image processor, digital signal processor, or any other suitable processor. The processor has data and / or signal processing capabilities. The processor may be implemented in software, in hardware, or a combination of both. Non-transitory computer-readable storage media include any suitable medium capable of storing program code, such as magnetic disks, hard disks, optical disks, flash memory, read-only memory, random access memory, etc. The term "A and / or B" means all possible combinations of A and B, such as only A, only B, or A and B. The singular terms "a" or "this" may also include plural forms.

[0049] As described in the background section, in order to address the problem that the speed of the outdoor fan of existing air conditioners cannot be adjusted based on the heat exchange requirements of the air conditioner, this invention provides an air conditioner control method.

[0050] See appendix Figure 1 , Figure 1 This is a schematic flowchart of the main steps of an air conditioning control method according to an embodiment of the present invention, wherein the air conditioning control method can be executed by a server, by the air conditioner, or by both the server and the air conditioner. Figure 1 As shown, the air conditioning control method of the present invention includes the following steps:

[0051] Step S101: Obtain the outer ring temperature and cold outlet temperature of the air conditioner, and / or obtain the return air temperature and coil temperature of the air conditioner.

[0052] Specifically, the outer ring temperature refers to the external ambient temperature, which can be obtained through an outer ring temperature sensor installed on the outdoor unit of the air conditioner; the cold outlet temperature is the temperature of the air outlet of the outdoor unit's condenser, which can be obtained through a cold outlet temperature sensor installed at the air outlet of the outdoor unit's condenser; the return gas temperature is the gas temperature at the compressor's suction inlet, which can be obtained through a return gas temperature sensor installed at the compressor's suction inlet; and the coil temperature is the coil temperature of the indoor unit's evaporator, which can be obtained through a coil temperature sensor installed on the indoor unit's evaporator coil.

[0053] Step S102: Control the speed of the outdoor fan of the air conditioner based on the outer ring temperature, the cold outlet temperature and / or the return air temperature and the coil temperature.

[0054] Based on the above steps S101 and S102, this invention obtains the outer ring temperature and cold outlet temperature of the air conditioner, and / or obtains the return air temperature and coil temperature of the air conditioner; based on the outer ring temperature, cold outlet temperature, and / or return air temperature and coil temperature, it controls the speed of the air conditioner's outdoor fan. This setting allows for adjustment of the outdoor fan speed based on the air conditioner's heat exchange requirements, improving the air conditioner's working efficiency, energy efficiency, and user experience.

[0055] In some embodiments, controlling the outdoor fan speed of the air conditioner based on the outer ring temperature, the cold outlet temperature and / or the return air temperature, and the coil temperature further includes the following steps:

[0056] Step S1021: When the air conditioner is running in cooling mode, a first temperature difference is obtained based on the outer ring temperature and the cold outlet temperature, and the speed of the air conditioner's outdoor fan is controlled based on the first temperature difference.

[0057] Step S1022: and / or, when the air conditioner is running in heating mode, a second temperature difference is obtained based on the return air temperature and the coil temperature, and the speed of the air conditioner's outdoor fan is controlled based on the second temperature difference.

[0058] Specifically, when the air conditioner is running in cooling mode, the first temperature difference is obtained by subtracting the outer ambient temperature from the cold outlet temperature. Because the closer the cold outlet temperature is to the outer ambient temperature when the air conditioner is running in cooling mode, the more efficient the heat exchange. Therefore, the speed of the outdoor fan can be controlled based on this first temperature difference. When the air conditioner is running in heating mode, the second temperature difference is obtained by subtracting the coil temperature from the return air temperature. Because the closer the return air temperature is to the coil temperature when the air conditioner is running in heating mode, the more efficient the heat exchange. Therefore, the speed of the outdoor fan can be controlled based on this second temperature difference.

[0059] See appendix Figure 2 , Figure 2 This is a schematic flowchart illustrating the main steps of controlling the outdoor fan speed of an air conditioner based on a first temperature difference, according to an embodiment of the present invention. Figure 2 As shown, in some embodiments, controlling the outdoor fan speed of the air conditioner based on the first temperature difference includes the following steps:

[0060] Step S201: Obtain the current speed of the outdoor fan of the air conditioner.

[0061] Step S202: Determine the first temperature difference range in which the first temperature difference is located.

[0062] Step S203: When the first temperature difference is within the first preset temperature difference range, control the air conditioner to maintain the current speed of the air conditioner's outdoor fan.

[0063] Step S204: When the first temperature difference is not within the first preset temperature difference range, control the air conditioner to perform the first outdoor fan speed adjustment operation.

[0064] Specifically, when the first temperature difference is within the first preset temperature difference range, it indicates that the air conditioning system has reached an optimal heat exchange state, so there is no need to adjust the speed of the outdoor fan; simply maintain the current outdoor fan speed. When the first temperature difference is not within the first preset temperature difference range, it indicates that the heat exchange effect of the air conditioning system is poor, so it is necessary to adjust the outdoor fan speed to improve the heat exchange effect of the air conditioning system.

[0065] For example, the first preset temperature difference range can be less than or equal to 3℃, that is, when the difference between the cold output temperature and the outer ring temperature is less than or equal to 3℃, the air conditioner is controlled to maintain the current outdoor fan speed. The value of the first preset temperature difference described above is only for illustrative purposes, and can be selected according to actual needs in practical applications.

[0066] See appendix Figure 3 , Figure 3 This is a schematic flowchart illustrating the main steps of controlling an air conditioner to perform a first outdoor fan speed adjustment operation according to an embodiment of the present invention. Figure 3 As shown, in some embodiments, when the first temperature difference is not within the first preset temperature difference range, controlling the air conditioner to perform the first outdoor fan speed adjustment operation includes the following steps:

[0067] Step S301: Determine the slope K based on the first temperature difference range where the first temperature difference is located, where the slope K is the adjustment value of the external fan speed per unit time.

[0068] Step S302: Based on the slope K and the formula R = R0 + Kt, control the air conditioner to perform the first outdoor fan speed adjustment operation, where R is the adjusted outdoor fan speed, R0 is the current outdoor fan speed of the air conditioner, and t is the duration of the air conditioner performing the first outdoor fan speed adjustment operation, and t is less than or equal to the first preset duration.

[0069] Specifically, multiple first temperature difference intervals can be set. When different first temperature differences are located within the same first temperature difference interval, the slope K takes the same value; simultaneously, the slope K is greater than 0, and the slope K increases as the value of the first temperature difference interval increases. Based on the formula R = R0 + Kt, the adjusted external fan speed at different times during the first external fan speed adjustment operation is obtained, and then the external fan speed is set to the adjusted external fan speed. This setting enables stepless speed regulation when changing the speed of the external fan, avoiding the situation where the external fan speed can only be adjusted between a few speed gears. This prevents sudden changes in the external fan speed, reduces fan noise, and further improves the user experience.

[0070] For example, the first temperature difference interval can be three: greater than 3℃ and less than or equal to 4℃, greater than 4℃ and less than or equal to 5℃, and greater than 5℃ and less than or equal to 6℃. The number of first temperature difference intervals and their sizes can be adjusted in the air conditioner's memory. The slope K, determined based on the first temperature difference interval, can be: 0.2 when the first temperature difference is greater than 3℃ and less than or equal to 4℃; 0.3 when the first temperature difference is greater than 4℃ and less than or equal to 5℃; and 0.4 when the first temperature difference is greater than 5℃ and less than or equal to 6℃. The first preset duration can be 15 seconds, meaning the first outdoor fan speed adjustment operation requires a total of 15 seconds, and the duration t for the air conditioner to perform the first outdoor fan speed adjustment operation gradually increases from 0 to 15 seconds. For example, when the current outdoor fan speed of the air conditioner is 20 revolutions per second, and the first temperature difference is in the range of greater than 4℃ and less than or equal to 5℃, the air conditioner needs to adjust the outdoor fan speed to 23 revolutions per second in the 10th second of the first outdoor fan speed adjustment operation.

[0071] The above-described settings for the number of first temperature difference intervals, the value settings for the first temperature difference intervals, the method for determining the slope K based on the first temperature difference interval in which the first temperature difference is located, and the value of the current air conditioner's outdoor fan speed are all just examples. In actual applications, these settings can be selected according to actual needs.

[0072] In some embodiments, when the first temperature difference is not within the first preset temperature difference range, controlling the air conditioner to perform the first outdoor fan speed adjustment operation includes the following steps:

[0073] Step S401: Determine the slope K and duration t based on the value of the first temperature difference and / or the first temperature difference range in which the first temperature difference is located, where the slope K is the adjustment value of the external fan speed per unit time, and the duration t is the duration for the air conditioner to perform the first external fan speed adjustment operation and t is less than or equal to the first preset duration.

[0074] Step S402: Based on the slope K, duration t and the formula R = R0 + Kt, control the air conditioner to perform the first outdoor fan speed adjustment operation, where R is the adjusted outdoor fan speed and R0 is the current outdoor fan speed of the air conditioner.

[0075] Specifically, the slope K is determined based on the first temperature difference interval in which the first temperature difference lies. That is, when different first temperature differences are located within the same first temperature difference interval, the slope K takes the same value; simultaneously, the value of the slope K is greater than 0, and the value of the slope K increases as the value of the first temperature difference interval in which the first temperature difference lies increases. The duration t is determined based on the value of the first temperature difference and the first temperature difference interval in which it lies. That is, when different first temperature differences are located within the same first temperature difference interval, the corresponding duration t is also different, and the duration t increases as the relative position of the first temperature difference value within its first temperature difference interval increases.

[0076] For example, the first temperature difference range may include a range greater than 4°C and less than or equal to 5°C. The duration t increases with the relative position of the first temperature difference value within the first temperature difference range. For example, when the first temperature difference value is 4.5°C, the duration t may be 7.5 seconds; when the first temperature difference value is 5°C, the duration t may be 15 seconds. The above-described method for setting the first temperature difference range and the method for determining the duration t based on the value of the first temperature difference and the first temperature difference range in which the first temperature difference is located are only illustrative examples. In practical applications, the appropriate method can be selected according to actual needs.

[0077] In some embodiments, before controlling the air conditioner to perform the first outdoor fan speed adjustment operation based on the slope K and the formula R = R0 + Kt, the method further includes: determining whether the adjusted outdoor fan speed is less than or equal to a speed threshold; when the adjusted outdoor fan speed is less than or equal to the speed threshold, controlling the air conditioner to perform the first outdoor fan speed adjustment operation based on the slope K and the formula R = R0 + Kt.

[0078] See appendix Figure 4 , Figure 4 This is a schematic flowchart illustrating the main steps of controlling the outdoor fan speed of an air conditioner based on a second temperature difference, according to an embodiment of the present invention. Figure 4 As shown, in some embodiments, controlling the outdoor fan speed of the air conditioner based on the second temperature difference includes the following steps:

[0079] Step S501: Obtain the current speed of the outdoor fan of the air conditioner.

[0080] Step S502: Determine the second temperature difference range in which the second temperature difference is located.

[0081] Step S503: When the second temperature difference is within the second preset temperature difference range, control the air conditioner to maintain the current speed of the air conditioner's outdoor fan.

[0082] Step S504: When the second temperature difference is not within the second preset temperature difference range, control the air conditioner to perform the second outdoor fan speed adjustment operation.

[0083] Specifically, when the second temperature difference is within the second preset temperature difference range, it indicates that the air conditioning system has reached an optimal heat exchange state, so there is no need to adjust the speed of the outdoor fan; simply maintain the current outdoor fan speed. When the second temperature difference is not within the second preset temperature difference range, it indicates that the heat exchange effect of the air conditioning system is poor, so it is necessary to adjust the speed of the outdoor fan to improve the heat exchange effect of the air conditioning system.

[0084] For example, the second preset temperature difference range can be less than or equal to 1°C. That is, when the difference between the return air temperature and the coil temperature is less than or equal to 1°C, the air conditioner is controlled to maintain the current outdoor fan speed. The value of the second preset temperature difference described above is only for illustrative purposes and can be selected according to actual needs in practical applications.

[0085] See appendix Figure 5 , Figure 5 This is a schematic flowchart illustrating the main steps of controlling an air conditioner to perform a second outdoor fan speed adjustment operation according to an embodiment of the present invention. Figure 5 As shown, in some embodiments, when the second temperature difference is not within the second preset temperature difference range, controlling the air conditioner to perform the second outdoor fan speed adjustment operation includes the following steps:

[0086] Step S601: Determine the slope K based on the second temperature difference interval where the second temperature difference is located, where the slope K is the adjustment value of the external fan speed per unit time.

[0087] Step S602: Based on the slope K and the formula R = R0 + Kt, control the air conditioner to perform the second outdoor fan speed adjustment operation, where R is the adjusted outdoor fan speed, R0 is the current outdoor fan speed of the air conditioner, and t is the duration of the air conditioner performing the second outdoor fan speed adjustment operation, and t is less than or equal to the second preset duration.

[0088] Specifically, multiple second temperature difference intervals can be set. When different second temperature differences are located within the same second temperature difference interval, the slope K takes the same value. Simultaneously, the slope K is greater than 0, and its value increases as the value of the second temperature difference interval increases. Based on the formula R = R0 + Kt, the adjusted external fan speed at different times during the second external fan speed adjustment operation is obtained, and then the external fan speed is set to the adjusted external fan speed.

[0089] For example, the second temperature difference interval can be four: greater than 1℃ and less than or equal to 2℃, greater than 2℃ and less than or equal to 3℃, greater than 3℃ and less than or equal to 4℃, and greater than 4℃ and less than or equal to 5℃. The number and size of the second temperature difference intervals can be adjusted in the air conditioner's memory. The slope K, determined based on the second temperature difference interval, can be: 0.1 when the second temperature difference is greater than 1℃ and less than or equal to 2℃; 0.2 when the second temperature difference is greater than 2℃ and less than or equal to 3℃; 0.3 when the second temperature difference is greater than 3℃ and less than or equal to 4℃; and 0.4 when the second temperature difference is greater than 4℃ and less than or equal to 5℃. The first preset duration can be 10 seconds, meaning the second outdoor fan speed adjustment operation requires a total of 10 seconds, and the duration t for the air conditioner to perform the second outdoor fan speed adjustment operation gradually increases from 0 to 10 seconds. For example, when the current outdoor fan speed of the air conditioner is 20 rpm and the second temperature difference is in the range of greater than 4℃ and less than or equal to 5℃, the air conditioner needs to adjust the outdoor fan speed to 24 rpm in the 10th second of the first outdoor fan speed adjustment operation.

[0090] The settings for the number of second temperature difference intervals, the values ​​of the second temperature difference intervals, the method for determining the slope K based on the second temperature difference interval in which the second temperature difference is located, and the current value of the outdoor fan speed of the air conditioner are all just examples. In actual applications, they can be selected according to actual needs.

[0091] In some embodiments, when the second temperature difference is not within the second preset temperature difference range, controlling the air conditioner to perform the second outdoor fan speed adjustment operation includes the following steps:

[0092] Step S701: Determine the slope K and duration t based on the value of the second temperature difference and / or the second temperature difference range in which the second temperature difference is located, where the slope K is the adjustment value of the external fan speed per unit time, and the duration t is the duration for the air conditioner to perform the second external fan speed adjustment operation and t is less than or equal to the second preset duration.

[0093] Step S702: Based on the slope K, duration t and the formula R = R0 + Kt, control the air conditioner to perform the second outdoor fan speed adjustment operation, where R is the adjusted outdoor fan speed and R0 is the current outdoor fan speed of the air conditioner.

[0094] Specifically, the slope K is determined based on the second temperature difference interval in which the second temperature difference lies. That is, when different second temperature differences are located within the same second temperature difference interval, the slope K takes the same value; simultaneously, the value of the slope K is greater than 0, and the value of the slope K increases as the value of the second temperature difference interval in which the second temperature difference lies increases. The duration t is determined based on the value of the second temperature difference and the second temperature difference interval in which it lies. That is, when different second temperature differences are located within the same second temperature difference interval, the corresponding duration t is also different, and the duration t increases as the relative position of the second temperature difference value within its second temperature difference interval increases.

[0095] In some embodiments, before controlling the air conditioner to perform the second outdoor fan speed adjustment operation based on the slope K and the formula R = R0 + Kt, the method further includes: determining whether the adjusted outdoor fan speed is less than or equal to a speed threshold; when the adjusted outdoor fan speed is less than or equal to the speed threshold, controlling the air conditioner to perform the second outdoor fan speed adjustment operation based on the slope K and the formula R = R0 + Kt.

[0096] In some embodiments, obtaining the outer ring temperature and cold outlet temperature of the air conditioner, and / or obtaining the return air temperature and coil temperature of the air conditioner includes the following steps:

[0097] Step S801: When the air conditioner is running in cooling mode, the outer ring temperature and the cold output temperature are obtained every third preset time interval.

[0098] Step S802: and / or, when the air conditioner is running in heating mode, the return air temperature and coil temperature are obtained every fourth preset time interval.

[0099] Specifically, when the air conditioner is running in cooling mode, the outer ring temperature and cold outlet temperature are acquired every third preset time interval after the air conditioner has been turned on for the fifth preset time interval. This is to detect the heat exchange status of the air conditioning system every third preset time interval, and then determine whether the air conditioner needs to perform the first outdoor fan speed adjustment operation again; and / or, when the air conditioner is running in heating mode, the return air temperature and coil temperature are acquired every fourth preset time interval after the air conditioner has been turned on for the sixth preset time interval. This is to detect the heat exchange status of the air conditioning system every fourth preset time interval, and then determine whether the air conditioner needs to perform the second outdoor fan speed adjustment operation again.

[0100] For example, the third, fourth, fifth, and sixth preset durations can all have the same value, such as setting them all to 3 minutes. Alternatively, multiple preset durations can be set to different values, such as setting the third preset duration to 2 minutes and setting the fourth, fifth, and sixth preset durations to 3 minutes. The values ​​of the third, fourth, fifth, and sixth preset durations described above are merely illustrative examples; in practical applications, they can be selected according to actual needs.

[0101] It should be noted that although the steps in the above embodiments are described in a specific order, those skilled in the art will understand that in order to achieve the effects of the present invention, different steps do not necessarily have to be executed in such an order. They can be executed simultaneously (in parallel) or in other orders, and these variations are all within the scope of protection of the present invention.

[0102] Furthermore, the present invention also provides an air conditioning control device.

[0103] See appendix Figure 6 , Figure 6 This is a schematic diagram of the main structure of an air conditioning control device according to an embodiment of the present invention.
