[0027] See also Figure 1 , an embodiment of the present invention provides a method for controlling an air conditioner, comprising steps S10-S40:

[0028] S10, when the air conditioner is in cooling mode, obtaining the current indoor temperature, and judging whether the indoor environment is in a stable state according to the indoor temperature;

[0029] In this step, it is necessary to check whether the air conditioner is in cooling mode, which can be achieved by obtaining the current working mode of the air conditioner. If the air conditioner is in cooling mode, the current indoor temperature is obtained through the temperature sensor, and the stable state of the indoor environment is confirmed according to the indoor temperature. In specific implementation, a set temperature (T 设), calculate the difference between the current indoor temperature and the set temperature, and determine whether the difference is within the preset temperature stability range. When the difference fluctuates within this stable range, it means that the indoor environment is stable; you can also obtain an indoor temperature value and obtain multiple indoor temperature values ​​at regular intervals, calculate the average value and standard deviation of these indoor temperature values, and if most of the indoor temperature values ​​are within the set stable range and the standard deviation is small (that is, it means that the indoor temperature does not fluctuate much), then the indoor environment is considered to be stable. In this embodiment, after the room is in a stable state, the air conditioner will turn on the anti-direct blowing mode to avoid the discomfort caused by cold wind.

[0030] S20, if it is a stable state, detecting the position of a person who has just entered the indoor environment, and controlling the air conditioner to discharge air toward the position;

[0031] In this step, when the indoor environment is in a stable state, someone suddenly enters the room from the outdoor where the temperature is high. At this time, the indoor temperature and air supply state cannot meet the cooling needs of these people who have just entered the room. If the set temperature is lowered, the compressor will increase its frequency and power consumption, which will also affect the comfort of other people in the room who have been in a stable state for a long time. Therefore, it is necessary to detect the position of the person who has just entered the indoor environment, and direct the air outlet of the air conditioner to discharge air towards the position of the person, so that the new person can immediately feel a comfortable temperature. This embodiment can achieve a cooling effect faster by accurately controlling the air outlet direction toward the position of the person. The method of controlling the air conditioner to discharge air toward the position includes: controlling the air guide plate of the air conditioner to sweep air left and right so that the wind direction is facing the position of the person entering the room, and turning on the up and down sweeping air.

[0032] S30, obtaining the current outdoor temperature, and determining whether the inner pipe temperature needs to be adjusted according to the outdoor temperature and the indoor temperature;

[0033] In this step, the difference between the outdoor temperature and the indoor temperature will directly affect the cooling effect of the air conditioning system. When the outdoor temperature is high, the air conditioning system needs to lower the inner pipe temperature to absorb and discharge heat more effectively, thereby providing sufficient cooling effect. Therefore, in the cooling mode, the outdoor temperature and indoor temperature are used to determine whether the inner pipe temperature needs to be adjusted.

[0034] In one embodiment, S30 includes:

[0035] Obtaining the current outdoor temperature, and calculating a first temperature difference between the outdoor temperature and the indoor temperature, wherein the first temperature difference is obtained by subtracting the indoor temperature from the outdoor temperature;

[0036] The indoor temperature and the first temperature difference value are matched with a preset first association table, and the adjustment range is confirmed based on the matching result, wherein the first association table includes adjustment ranges associated with multiple different indoor temperature ranges and multiple different first temperature difference value ranges, and the adjustment ranges include range values ​​that do not require adjustment of the inner pipe temperature, range values ​​that require increasing the inner pipe temperature, and range values ​​that require decreasing the inner pipe temperature.

[0037] In this embodiment, a first association table is prepared in advance, which includes a plurality of different indoor temperature ranges and a plurality of different first temperature difference value ranges. For each combination of the indoor temperature range and the first temperature difference value range, a corresponding adjustment range is set in the first association table. The adjustment range may include three situations: no need to adjust the inner tube temperature (such as "0" indicating no change), need to increase the inner tube temperature (such as "+1°C", "+2°C", etc. indicating an increase range value) and need to reduce the inner tube temperature (such as "-1°C", "-2°C", etc. indicating a decrease range value). The preset first association table can be set according to Table 1:

[0038] Table 1

[0039]

[0040] Among them, T 内环 is the indoor temperature obtained, T 外环 -T 内环 is the first temperature difference between the outdoor temperature and the indoor temperature, 0 indicates that the amplitude value of the inner tube temperature does not need to be adjusted, "-" indicates that the inner tube temperature needs to be lowered, and the specific value indicates the amplitude value that needs to be lowered. It should be noted that since this embodiment is aimed at whether the inner tube temperature needs to be adjusted in the cooling mode, when the inner tube temperature needs to be adjusted, only by lowering the inner tube temperature can the user's cooling demand be met. Therefore, the adjustment amplitude in Table 1 does not increase the inner tube temperature.

[0041] Then, the obtained indoor temperature and the calculated first temperature difference are matched with the indoor temperature range and the first temperature difference range in the first association table, respectively, and the corresponding adjustment range is confirmed according to the matching result, and the internal pipe temperature of the air-conditioning system is adjusted according to the adjustment range. For example, the indoor temperature range in Table 1 includes three indoor temperature ranges of ≤26°C, greater than 26°C and less than 28°C, and ≥28°C, and the first temperature difference range includes three first temperature difference ranges of ≥8°C, greater than or equal to 4°C and less than 8°C, and greater than or equal to 0°C and less than 4°C. If the obtained indoor temperature is 29°C and the first temperature difference is 9°C, then the adjustment range can be matched from Table 1 to -6°C.

[0042] S40: If necessary, adjust the inner tube temperature.

[0043] In this step, by adjusting the inner pipe temperature, the air conditioner can more quickly meet the cooling needs of people who have just entered the room, and the air conditioner can operate more efficiently, thereby reducing energy consumption.

[0044] In one embodiment, if Figure 2 As shown, S40 includes:

[0045] S41, obtaining the adjustment range;

[0046] S42, comparing the adjustment amplitude with a preset amplitude value;

[0047] S43, if the adjustment amplitude is less than or equal to the preset amplitude value, adjusting the inner pipe temperature by adjusting the compressor frequency;

[0048] S44. If the adjustment amplitude is greater than the preset amplitude value, the inner pipe temperature is adjusted by adjusting the rotation speed of the outer fan.

[0049] In this embodiment, the adjustment amplitude obtained by matching the first association table is obtained, and an amplitude value threshold (i.e., a preset amplitude value) is set. The threshold is used to determine which adjustment method is used to adjust the internal pipe temperature. The determination method can refer to the above steps. The threshold value can be set according to the performance of the air conditioner, the requirements of the indoor environment, and the user's preference. Among them, the preset amplitude value can be -4°C.

[0050] If the inner pipe temperature is adjusted by adjusting the compressor frequency, the operating frequency of the compressor is increased or decreased according to the specific value of the adjustment range. In cooling mode, the cooling capacity of the air conditioner needs to be improved, so the inner pipe temperature needs to be reduced. At this time, the compressor frequency needs to be increased; if the inner pipe temperature is adjusted by adjusting the speed of the external fan, the speed of the external fan needs to be increased or decreased according to the specific value of the adjustment range. In cooling mode, the cooling capacity of the air conditioner needs to be improved, so the inner pipe temperature needs to be reduced. At this time, the speed of the external fan needs to be increased, thereby enhancing the heat dissipation effect of the heat exchanger in the air conditioner, which helps to reduce the inner pipe temperature.

[0051] In one embodiment, S43 includes:

[0052] Matching the adjustment amplitude with a preset second association table, and selecting the adjustment frequency of the compressor frequency according to the matching result; wherein the second association table includes adjustment frequencies associated with a plurality of different adjustment amplitude ranges;

[0053] Increase the compressor frequency by the adjustment frequency described.

[0054] In this embodiment, a second association table is prepared in advance, which includes a plurality of different adjustment amplitude ranges, and corresponding adjustment frequencies are set within the corresponding adjustment amplitude ranges, wherein the smaller the adjustment amplitude range, the larger the corresponding adjustment frequency setting. The preset second association table can be specifically set according to Table 2:

[0055] Table 2

[0056] <![CDATA[T f ]]> [-4，-5) [-5，-6) ≤-6 <![CDATA[△f1]]> 1 2 3

[0057] Among them, T f is the adjustment amplitude obtained, and △f1 is the adjustment frequency. It should be noted that since the present embodiment is aimed at reducing the inner tube temperature in the refrigeration mode to achieve a better refrigeration effect, only by increasing the compressor frequency can the user's refrigeration needs be met. Therefore, in Table 2, the smaller the adjustment amplitude, the greater the adjustment frequency. In specific implementation, the compressor frequency can be adjusted every first predetermined time (for example, 10 minutes) to avoid excessive adjustment, that is, to prevent overshoot. For example, the adjustment amplitude range in Table 2 includes three adjustment amplitude ranges: [-4, -5), [-5, -6) and ≤-6. When the obtained adjustment amplitude is -5°C, the adjustment frequency matched from Table 2 is 2Hz.

[0058] In one embodiment, S44 includes:

[0059] Matching the adjustment amplitude with a preset third association table, and selecting the adjustment speed of the external fan speed according to the matching result; wherein the third association table includes adjustment speeds associated with a plurality of different adjustment amplitude ranges;

[0060] Increase the speed of the external fan by adjusting the speed as described.

[0061] In this embodiment, a third association table is prepared in advance, which includes a plurality of different adjustment amplitude ranges, and corresponding adjustment speeds are set in the corresponding adjustment amplitude ranges, wherein the smaller the adjustment amplitude range, the larger the corresponding adjustment speed setting. The preset third association table can be specifically set according to Table 3:

[0062] Table 3

[0063] <![CDATA[T f ]]> (0，-2) [-2，-3) [-3，-4) <![CDATA[△R1]]> 10 20 30

[0064] Among them, T fThe adjustment range is obtained, and △R1 ​​is the adjustment speed. It should be noted that since the present embodiment is aimed at reducing the inner tube temperature in the cooling mode to achieve a better cooling effect, only by increasing the speed of the external fan can the user's cooling needs be met. Therefore, in Table 3, the smaller the adjustment range, the greater the adjustment speed. In specific implementation, the speed of the external fan can be adjusted every second predetermined time (for example, 5 minutes) to avoid excessive adjustment, that is, to prevent overshoot. Among them, the first predetermined time is greater than the second predetermined time. For example, the adjustment range in Table 3 includes three adjustment ranges: (0, -2), [-2, -3) and [-3, -4). When the obtained adjustment range is -2°C, the adjustment speed matched from Table 3 is 20rpm.

[0065] like Figure 3 As shown, the control method also includes:

[0066] S50, selecting a wind speed of the indoor fan according to the temperature difference between the outdoor temperature and the indoor temperature.

[0067] In this step, in order to more quickly meet the cooling needs of people who have just entered the indoor environment, it is also necessary to adjust the wind speed of the indoor fan according to the temperature difference between the outdoor temperature and the indoor temperature. In addition, regardless of whether the internal pipe temperature needs to be adjusted, the wind speed of the indoor fan needs to be adjusted.

[0068] In one embodiment, S50 includes:

[0069] If the inner pipe temperature needs to be adjusted, a first temperature difference between the outdoor temperature and the indoor temperature is obtained, and a second temperature difference between the inner pipe temperature and the target pipe temperature is obtained, wherein the first temperature difference is obtained by subtracting the indoor temperature from the outdoor temperature, and the second temperature difference is obtained by subtracting the target pipe temperature from the inner pipe temperature;

[0070] The first temperature difference value and the second temperature difference value are matched with a preset fourth association table, and the wind speed of the internal fan is selected according to the matching result, wherein the fourth association table includes wind speeds associated with multiple different first temperature difference value ranges and multiple different second temperature difference values.

[0071] This embodiment is a specific method for adjusting the wind speed of the inner fan when the inner pipe temperature needs to be adjusted, that is, a fourth association table is prepared in advance, the table includes a plurality of different first temperature difference ranges and a plurality of different second temperature difference values, and a corresponding wind speed is set for each first temperature difference range and second temperature difference value, wherein the F1-F5 gears gradually increase, and the preset fourth association table can be specifically set according to Table 4:

[0072] Table 4

[0073]

[0074] Among them, T外环 -T 内环 is the first temperature difference between outdoor temperature and indoor temperature, T 内管 -T 目标内管 The second temperature difference between the inner tube temperature and the target tube temperature is then calculated, and the first temperature difference and the second temperature difference are matched with the first temperature range and the second temperature difference in the fourth association table respectively. According to the matching result, the wind speed of the inner fan is confirmed and the wind speed of the inner fan is adjusted. In the specific implementation, the wind speed is updated every third preset time (such as 10 minutes), and the third preset time can be set to be the same as the first preset time, or it can be set to be different. For example, the first temperature difference range in Table 4 includes three first temperature difference ranges of ≥8°C, greater than or equal to 4°C and less than 8°C, and greater than or equal to 0°C and less than 4°C. The second temperature difference includes 1, 2, 3, 4, 5, and 6, a total of 6 second temperature difference values. If the indoor temperature obtained is 20°C and the outdoor temperature is 32°C, the first temperature difference is 12°C. If the inner tube temperature obtained is 17°C and the target tube temperature is 15°C, the second temperature difference is 2°C, then the wind speed that can be matched from Table 4 is F3.

[0075] In one embodiment, S50 further includes:

[0076] If the inner pipe temperature does not need to be adjusted, a first temperature difference between the outdoor temperature and the indoor temperature is obtained, where the first temperature difference is obtained by subtracting the indoor temperature from the outdoor temperature;

[0077] The indoor temperature and the first temperature difference value are matched with a preset fifth association table, and the wind speed of the indoor fan is selected according to the matching result, wherein the fifth association table includes wind speeds associated with multiple different indoor temperature ranges and multiple different first temperature difference value ranges.

[0078] This embodiment is a specific method for adjusting the wind speed of the indoor fan without adjusting the internal pipe temperature, that is, a fifth association table is prepared in advance, the table includes multiple different indoor temperature ranges and multiple different first temperature difference value ranges, and a corresponding wind speed is set for each indoor temperature range and first temperature difference value range, wherein the F1-F5 gears gradually increase. The preset fifth association table can be specifically set according to Table 5:

[0079] Table 5

[0080]

[0081] Among them, T 外环 -T 内环 is the first temperature difference between outdoor temperature and indoor temperature, T 内环To obtain the indoor temperature, the calculated first temperature difference value and the obtained indoor temperature are matched with the first temperature value range and the indoor temperature range in the fifth association table respectively, and the windshield size of the indoor fan is confirmed according to the matching result and the windshield of the indoor fan is adjusted. In the specific implementation, the intensity of the windshield is not limited to 5 winds, and can be adjusted according to actual needs. After running the air conditioner to the maximum running time (which can be set to 20min), manually or automatically exit the cooling mode. For example, in Table 5, there are three first temperature difference ranges of indoor temperature range ≥8℃, greater than or equal to 4℃ and less than 8℃, greater than or equal to 0℃ and less than 4℃, and the indoor temperature range includes ≤25℃, 26℃, 27℃, ≥28℃, a total of four indoor temperature ranges. If the indoor temperature obtained is 24℃ and the outdoor temperature is 28℃, the first temperature difference value is 4℃, then the windshield that can be matched from Table 5 is F2.
