[0046] In the description of the present application, unless otherwise explicitly limited, the words such as setting, installing, connecting, etc. should be broadly understood, and those skilled in the art can reasonably determine the specific meaning of the above words in the present application in combination with the specific content of the technical solution.

[0047] The various embodiments of the control method of the air conditioner according to the present application will be further described below with reference to the accompanying drawings.

[0048] Referring to Fig. 1, the control method of the air conditioner according to an embodiment of the present application includes, but is not limited to, steps S100 to S300.

[0049] In step S100, an indoor temperature is acquired.

[0050] In step S200, in response to the indoor temperature being less than a set temperature, an outdoor temperature is acquired.

[0051] In step S300, the operating frequency of the air conditioner is adjusted according to the outdoor temperature.

[0052] It can be understood that the indoor temperature is acquired when the air conditioner is running, and then whether the indoor temperature is less than the set temperature is determined according to comparison between the indoor temperature and the set temperature. When the indoor temperature is greater than or equal to the set temperature, it indicates that the current indoor temperature is relatively high, and the preset temperature of the user is not reached, at this time, the air conditioner can be controlled to keep the current working mode to continue running, for example, when the current working mode is the cooling mode, the air conditioner continues to run cooling according to the set parameters of the cooling mode.

[0053] When the indoor temperature is less than the set temperature, it indicates that the indoor temperature is less than the set temperature, at this time, the current indoor temperature is lower than the preset temperature of the user, the running frequency of the air conditioner can be controlled to be reduced to achieve the purpose of energy saving, for example, when the indoor temperature is less than the set temperature, the cooling mode is switched to the energy saving mode, and the air conditioner continues to run according to the working frequency of the energy saving mode.

[0054] Since when the outdoor temperature is high, the heat load of the room is also high, which is easy to cause the indoor temperature to rise too fast, affecting the comfort of the user, therefore, when the indoor temperature is less than the set temperature, the outdoor temperature is acquired, and then the running frequency of the air conditioner is adjusted according to the high and low of the outdoor temperature, for example, when the outdoor temperature is higher than 38℃, the running frequency of the air conditioner is controlled to be increased; when the outdoor temperature is lower than 26℃, the running frequency of the air conditioner is controlled to be reduced. When the indoor temperature is reduced to the appropriate range, the air conditioner runs according to the adjusted running frequency, which can realize dynamic finding of the balance point of the capacity output of the air conditioner and the heat load of the room, so as to keep the temperature of the room in the appropriate range, and improve the comfort of the user.

[0055] Referring to FIG. 1, the air conditioner control method of the embodiment includes but is not limited to step S400.

[0056] Step S400, in response to the indoor temperature being greater than or equal to the set temperature, the maximum running frequency of the air conditioner is controlled to be increased, and when the indoor temperature is less than the set temperature, the air conditioner is controlled to return to the running frequency before the increase.

[0057] It can be understood that when the indoor temperature is greater than or equal to the set temperature, it indicates that the current indoor temperature is relatively high, in some embodiments, the maximum running frequency of the air conditioner is controlled to be increased to avoid running at a fixed low frequency, the maximum running frequency can be the working frequency of the air conditioner in the cooling mode, or the working frequency when the air conditioner runs at the maximum power, which can quickly increase the cooling output capacity, so as to quickly reduce the indoor temperature. When the indoor temperature is reduced to be less than the set temperature, it indicates that the indoor temperature is reduced to the appropriate range, at this time, the running frequency before the increase is restored, that is, the original running frequency, which can not only ensure the better comfort of the user, but also meet the needs of energy saving and power saving.

[0058] It should be noted that, after the original operating frequency is restored, the indoor temperature is less than the set temperature at this time, so the above step S300 is continued, that is, the operating frequency of the air conditioner is adjusted according to the outdoor temperature.

[0059] Referring to FIG. 2, the control method is described below with a specific example. The air conditioner control method includes but is not limited to steps S110 to S130.

[0060] Step S110, in the case that the air conditioner enters the energy-saving mode, the indoor temperature and the outdoor temperature are obtained;

[0061] Step S120, in response to the indoor temperature being greater than or equal to the set temperature, the air conditioner is controlled to switch from the energy-saving mode to the cooling mode, and until the indoor temperature is less than the set temperature, the cooling mode is restored to the energy-saving mode;

[0062] Step S130, the operating frequency of the air conditioner is adjusted according to the current outdoor temperature.

[0063] It can be understood that the air conditioner control method of the embodiment is applicable to a cooling and heating type air conditioner or a single cooling type air conditioner, and can also be a wall-mounted air conditioner, a cabinet type air conditioner or a mobile air conditioner, etc. Taking a cooling and heating type air conditioner as an example, the working modes of the air conditioner include a cooling mode, a heating mode, an energy-saving mode, an initial mode, etc., wherein the cooling mode and the energy-saving mode are two common working modes of the air conditioner. The cooling mode has the characteristics of fast cooling speed and significant cooling effect, which can quickly reduce the indoor temperature, but the power consumption is relatively large; the energy-saving mode is also called ECO mode, which aims to save electricity by reducing energy consumption, but the cooling efficiency will be affected to a certain extent. It should be noted that, since the air conditioner is in a cooling state in the energy-saving mode, the cooling mode is also called the normal cooling mode relative to the energy-saving mode.

[0064] In the above step S110, when the user uses the air conditioner, he / she can select a suitable working mode according to the actual demand, when the energy-saving mode is selected, the air conditioner enters the working state of the energy-saving mode, at this time, the indoor temperature, the outdoor temperature, the set temperature and the operating frequency of the air conditioner are obtained, wherein the indoor temperature is the indoor environmental temperature of the room, the outdoor temperature is the outdoor environmental temperature, and the operating frequency of the air conditioner is the operating frequency of the compressor. When entering the energy-saving mode, the purpose of reducing energy consumption is achieved by reducing the operating frequency of the compressor.

[0065] It should be noted that the set temperature can be a parameter preset according to the number of matches, type, etc. of the air conditioner, or it can be set by the user through a remote controller or a mobile terminal when in use, for example, the user selects the cooling mode and sets the set temperature to 28℃ when starting the machine. The air conditioner will deliver cold air to the indoor to adjust the indoor temperature to the vicinity of the set temperature.

[0066] In some embodiments, the indoor temperature and the outdoor temperature are acquired by sensors. For example, in a wall-mounted air conditioner, temperature sensors are installed in the indoor unit and the outdoor unit respectively, and the indoor temperature and the outdoor temperature are detected by the temperature sensors of the indoor unit and the outdoor unit respectively.

[0067] It can be understood that, since the refrigeration efficiency of the air conditioner is reduced in the energy-saving mode, the refrigeration output capacity of the air conditioner, also referred to as the refrigeration capacity, is also reduced. When the refrigeration output capacity is less than the room heat load, the temperature of the room will slowly rise, and the user comfort will be reduced when the indoor temperature exceeds the temperature range suitable for human comfort.

[0068] To improve the above situation, the air conditioner control method of the embodiments of the present application compares the acquired indoor temperature with the set temperature. When the indoor temperature is greater than or equal to the set temperature, it indicates that the indoor temperature exceeds the suitable temperature range, and the user comfort is reduced. At this time, the air conditioner is automatically switched from the energy-saving mode to the refrigeration mode. Since the operating frequency of the compressor is limited at a lower level in the energy-saving mode, the refrigeration capacity is reduced. When switched to the refrigeration mode, the compressor resumes the operating frequency of normal work, thereby improving the refrigeration output capacity, and the indoor temperature will rapidly decrease in the refrigeration mode. When the indoor temperature decreases to less than the set temperature, the refrigeration mode is restored to the energy-saving mode, that is, re-entering the energy-saving mode, which can ensure that the user has better comfort and meet the needs of energy saving and power saving.

[0069] It should be noted that, considering that the indoor temperature is easy to rise under the condition that the room is subject to a high heat load, for example, when the outdoor environment temperature is high, the larger the indoor-outdoor temperature difference, the higher the room heat load; for example, the area of the room directly exposed to sunlight is large, and the heat load is also high, and the indoor temperature is easy to rise. Therefore, in order to solve the problem of high room heat load, in the embodiments, when the air conditioner re-enters the energy-saving mode, the energy-saving mode does not work according to the original operating frequency, and the operating frequency of the compressor is adjusted according to the current outdoor temperature. For example, when the current outdoor temperature is detected to be high, the current operating frequency can be adjusted to be higher than the original operating frequency, and the energy-saving mode operates according to the adjusted operating frequency, thereby reducing the rising efficiency of the indoor temperature in the energy-saving mode and reducing the situation that the indoor temperature is higher than the set temperature.

[0070] It should be noted that, in the related art, the switching between the refrigeration mode and the energy-saving mode is controlled only by comparing the indoor temperature with the set temperature, which is easy to cause frequent switching between the two modes, which is not conducive to reducing energy consumption. The embodiments of the present application adjust the operating frequency of the compressor according to the current outdoor temperature, which can dynamically find the balance point of the air conditioner capacity output and the room heat load, keep the indoor temperature in a suitable range, and effectively improve the user comfort.

[0071] In some embodiments, when the indoor temperature is greater than or equal to the set temperature, the maximum operating frequency of the air conditioner is controlled to be increased, and the maximum rotating speed of the fan, specifically the supply fan of the indoor unit, is also increased. By increasing the maximum rotating speed, the heat exchange efficiency of indoor air can be accelerated, thereby improving the refrigeration output capacity and further improving the speed of indoor temperature drop. When the indoor temperature drops to less than the set temperature, the operating frequency is restored to the original operating frequency, and the rotating speed of the fan is also restored to the original rotating speed, so that the air conditioner reenters the energy-saving mode.

[0072] Referring to FIG. 3, regarding the step of adjusting the operating frequency of the air conditioner according to the current outdoor temperature, the step can include, but is not limited to, step S210, step S220, and step S230.

[0073] In step S210, in response to the outdoor temperature being greater than or equal to a first threshold temperature, the first preset frequency is used as the operating frequency.

[0074] Referring to FIG. 4, which shows a coordinate graph of the outdoor temperature and the operating frequency. It can be understood that when the outdoor temperature is high, the room heat load is high, the indoor temperature rises quickly, and the required refrigeration output capacity is also high. In the embodiment, the first threshold temperature and the first preset frequency are set. When the outdoor temperature is greater than the first threshold temperature, it indicates that the outdoor temperature is high, and the room heat load is high. Therefore, the compressor is controlled to work at the first preset frequency as the operating frequency in the energy-saving mode, wherein the first preset frequency is a preset parameter corresponding to the first threshold temperature, and the first preset frequency can be set to be higher than the original operating frequency to meet the cooling requirement of high room heat load. Specifically, the first threshold temperature and the first preset frequency can be set according to the actual outdoor temperature data of the region, for example, as shown in FIG. 4, the first threshold temperature Tn1 is set to 43℃, and the first preset frequency F1 is set to 30Hz. When the outdoor temperature T2≥43℃, the operating frequency of the compressor is 30Hz.

[0075] In step S220, in response to the outdoor temperature being less than or equal to a second threshold temperature, the second preset frequency is used as the operating frequency.

[0076] It can be understood that when the outdoor temperature is low, the room heat load is not high, and the required refrigeration output capacity is small, for example, the set temperature is 26℃, and the outdoor temperature is 28℃, the indoor and outdoor temperature difference is small. In the embodiment, the second threshold temperature and the second preset frequency are set, the first threshold temperature is greater than the second threshold temperature, and the first preset frequency is greater than the second preset frequency. When the outdoor temperature is less than the second threshold temperature, it is indicated that the outdoor temperature is small, and the room heat load is not high, so that the compressor is controlled to work in the energy-saving mode with the second preset frequency as the operating frequency. The second preset frequency is a preset parameter corresponding to the second threshold temperature, and the second preset frequency is relatively lower than the original operating frequency, so that the room heat load requirement can be met, and the energy consumption can be further reduced. For example, referring to the second threshold temperature Tn2 shown in FIG. 4, the second preset frequency F2 is set to 5Hz, and when the outdoor temperature T2≤30℃, the operating frequency of the compressor is 5Hz.

[0077] In step S230, in response to the outdoor temperature being greater than the second threshold temperature and less than the first threshold temperature, the operating frequency is adjusted to satisfy F0=(F1-F2)*(T2-Tn2) / (Tn1-Tn2)+F2, wherein F0 is the operating frequency, F1 is the first preset frequency, F2 is the second preset frequency, Tn1 is the first threshold temperature, Tn2 is the second threshold temperature, and T2 is the current outdoor temperature.

[0078] When the outdoor temperature is greater than or equal to the second threshold temperature and less than or equal to the first threshold temperature, it is indicated that the outdoor temperature is in a relatively high temperature range, which has a greater impact on the room heat load, and the interval range of the outdoor temperature is a common temperature range for users to use the air conditioner to cool, therefore, the operating frequency is dynamically adjusted by using the above formula to obtain a more reasonable operating frequency. The values of the first preset frequency and the second preset frequency can be set according to the number of matches of the air conditioner and the outdoor environment data of the actual application area, and are not limited specifically.

[0079] With reference to FIG. 4, the first threshold temperature Tn1 is set to 43℃, the first preset frequency F1 is set to 30Hz, the second threshold temperature Tn2 is set to 30℃, and the second preset frequency F2 is set to 5Hz. When 30℃ < T2 < 43℃, F0 = (F1-F2)*(T2-Tn2) / (Tn1-Tn2)+F2 = (30-5)*(T2-30) / (43-30)+5. For example, when T2 = 32℃, the running frequency F0 calculated according to the above formula is 8.8Hz. For another example, when T2 = 38℃, the running frequency F0 calculated is 20.4Hz. As shown in FIG. 3, when the outdoor temperature is between 30℃ and 43℃, the curve of the running frequency changes at a certain slope, satisfying F0 = (F1-F2)*(T2-Tn2) / (Tn1-Tn2)+F2. In the case of obtaining the current outdoor temperature, the running frequency corresponding to the current outdoor temperature can be quickly determined.

[0080] When the air conditioner re-enters the energy-saving mode, the running frequency of the compressor is adjusted according to the current outdoor temperature, and the energy-saving mode is run according to the adjusted running frequency. The higher the outdoor temperature, the higher the running frequency adjusted according to the above steps S210 to S230. Similarly, the lower the outdoor temperature, the lower the adjusted running frequency. Therefore, when entering the energy-saving mode, the running frequency of the energy-saving mode can be corrected according to the outdoor temperature, and compared with the way of running the energy-saving mode at a lower fixed frequency, the control method of the embodiment of the application can dynamically find the balance point of the refrigeration capacity output of the air conditioner and the room heat load, effectively improving the user's comfort.

[0081] It should be noted that the embodiment of the application can dynamically adjust the running frequency when the outdoor temperature exceeds the second threshold temperature, so that the energy-saving mode runs more reasonably, effectively reduces the speed of the indoor temperature rising without frequently switching to the refrigeration mode, avoids frequent switching to the refrigeration mode, and further reduces the energy consumption.

[0082] With reference to FIG. 5, the air conditioner control method of the embodiment of the application further includes but is not limited to steps S140 and S150, and steps S140 and S150 are executed after step S130.

[0083] In step S140, after the air conditioner is controlled to run at the adjusted running frequency for a first time length, the change of the current indoor temperature is judged.

[0084] In step S150, in response to the current indoor temperature being greater than the fourth threshold temperature and less than the third threshold temperature, the running frequency is adjusted according to the current outdoor temperature to re-determine the running frequency.

[0085] Since the running frequency is changed after the above steps S210 to S230 are performed, the indoor temperature changes greatly, and thus it is necessary to observe the change of the indoor temperature after running for a certain time duration according to the adjusted running frequency, so as to determine whether the running frequency is reasonable. For example, the first time duration can be set to 30 minutes, and the adjusted running frequency is 20.4 Hz. The running frequency of 20.4 Hz is continued to run for 30 minutes when the refrigeration mode is switched to the energy-saving mode, and then the current change of the indoor temperature is determined. The first time duration is not limited to 30 minutes, and can be set according to actual use requirements.

[0086] It can be understood that the interval in which the indoor temperature is greater than the fourth threshold temperature and less than the third threshold temperature is a temperature rising interval, the temperature rising interval indicates that the indoor temperature is in a rising stage, and the third threshold temperature is used to determine whether the indoor temperature exceeds the upper limit of the temperature rising interval. If the indoor temperature does not exceed the third threshold temperature, it indicates that the indoor temperature does not exceed the appropriate temperature range. For example, the first time duration is 30 minutes, and the third threshold temperature is 32°C. After 30 minutes, the indoor temperature changes slowly. At this time, if it is detected that the current indoor temperature enters the temperature rising interval and the indoor temperature T1 < 32°C, it indicates that the indoor temperature is rising but does not exceed the appropriate temperature range, and the user's feeling is still in a comfortable state. The step of adjusting the running frequency according to the current outdoor temperature is repeatedly performed every 30 minutes, that is, the running frequency is re-determined according to the above steps S210 to S230, and the running frequency of the energy-saving mode is corrected.

[0087] Since the rising speed of the indoor temperature is related to the outdoor temperature, if the outdoor temperature T2 < 30°C, the room heat load is not high, and the indoor temperature is in the temperature rising interval, but the rising amplitude is slow. At this time, the second preset frequency can be used as the running frequency according to the above step S220. If the outdoor temperature T2 = 34°C, the running frequency can be adjusted according to the formula F0 = (F1-F2)*(T2-T n2 ) / (T n1 -T n2 )+F2 in the above step S230, and the running is continued for 30 minutes after the running frequency is re-determined, and then it is repeatedly determined whether the current indoor temperature enters the temperature rising interval and is less than the third threshold temperature. It can be understood that, in the case that the outdoor temperature is unchanged, the slower the rising speed of the indoor temperature is, the more suitable the adjusted running frequency is, and the more beneficial it is to maintain the stability of the indoor temperature. For example, the running frequency that rises by 3°C in 3 hours is more suitable than the running frequency that rises by 3°C in 1 hour. Therefore, in the case that the indoor temperature does not exceed the third threshold temperature, the running frequency is re-determined every 30 minutes to obtain a better running frequency, so as to achieve the purpose of dynamically correcting the running frequency of the energy-saving mode, which can ensure the comfort of the user and reduce energy consumption.

[0088] Referring to FIG. 5, the air conditioner control method of the embodiments of the present application further includes, but is not limited to, step S160 and step S170, and step S160 and step S170 are executed after step S140.

[0089] In step S160, in response to the current indoor temperature being greater than or equal to the third threshold temperature, the air conditioner is controlled to switch from the energy-saving mode to the cooling mode.

[0090] In step S170, in response to the indoor temperature dropping to the fourth threshold temperature, the cooling mode is restored to the energy-saving mode, and the operating frequency is readjusted.

[0091] It can be understood that the current indoor temperature being greater than or equal to the third threshold temperature indicates that the indoor temperature is out of the appropriate temperature range, i.e., the indoor temperature is too high, and the user comfort is reduced. At this time, the air conditioner is controlled to switch from the energy-saving mode to the cooling mode, the compressor is restored to the normal operating frequency, and the cooling output capacity is improved, so as to rapidly reduce the indoor temperature. In the cooling mode, the indoor temperature enters the temperature drop interval, which can ensure that the comfort is rapidly improved.

[0092] In some embodiments, when the current indoor temperature is greater than or equal to the third threshold temperature, the maximum operating frequency of the air conditioner is controlled to be increased, i.e., the current operating frequency is increased to the operating frequency in the cooling mode or the operating frequency at the maximum power operation, until the indoor temperature drops to the fourth threshold temperature, and then the air conditioner is controlled to be restored to the original operating frequency. It should be noted that in other embodiments, while the operating frequency is increased, the maximum rotating speed of the fan can also be increased, so as to effectively improve the cooling output capacity of the air conditioner, and rapidly reduce the indoor temperature to the fourth threshold temperature. In addition, when the indoor temperature drops to less than the set temperature, the operating frequency is restored to the operating frequency before the increase, and the rotating speed of the fan is restored to the original rotating speed, so that the air conditioner reenters the energy-saving mode, which can ensure the user comfort and meet the energy-saving and power-saving requirements.

[0093] In the embodiments, the fourth threshold temperature is used to determine whether the indoor temperature is out of the lower limit of the temperature drop interval. It can be understood that when the indoor temperature drops to less than the fourth threshold temperature, it indicates that the indoor temperature is lower than the appropriate range, and it is not conducive to reduce the energy consumption to continue operating in the cooling mode. Therefore, when the indoor temperature drops to the fourth threshold temperature, the cooling mode is restored to the energy-saving mode, and the operating frequency is readjusted. The operating frequency can be adjusted according to the outdoor temperature, as described in the adjustment process of steps S210 to S230.

[0094] Referring to FIG. 6, FIG. 6 shows a coordinate relationship between the temperature rising interval and the temperature falling interval. In the coordinate diagram, the area on the left side of the bending line represents the temperature rising interval A, the straight line with an arrow represents the temperature rising trend, the area on the right side of the bending line represents the temperature falling interval B, and the straight line with an arrow represents the temperature falling trend. T 1A represents the third threshold temperature, T 1B represents the fourth threshold temperature. For example, the third threshold temperature T 1A is set to 32°C, and the fourth threshold temperature T 1B is set to 28°C. When the indoor temperature T1≥32°C, the energy-saving mode is switched to the refrigeration mode, and the indoor temperature enters the temperature falling interval. When the indoor temperature T1<28°C, the refrigeration mode is restored to the energy-saving mode, and the operating frequency is adjusted according to the current outdoor temperature.

[0095] It should be noted that, regarding the determination of the temperature rising interval and the temperature falling interval, the indoor temperature values at different times can be compared to determine whether the indoor temperature is in a rising trend or a falling trend. For example, the temperatures collected at the current time and the last time are compared. If the temperature at the current time is greater than the temperature at the last time, it indicates that the indoor temperature is in a rising trend, that is, the indoor temperature is in the temperature rising interval. Conversely, if the temperature at the current time is less than the temperature at the last time, it indicates that the indoor temperature is in a falling trend, that is, the indoor temperature is in the temperature falling interval. When the indoor temperature rises by more than the third threshold temperature T 1A , the energy-saving mode is switched to the refrigeration mode, and the indoor temperature enters the temperature falling interval. When the indoor temperature falls by more than the fourth threshold temperature T 1B , the refrigeration mode is restored to the energy-saving mode, and the indoor temperature returns to the temperature rising interval. In some embodiments, the value range of T 1A is 29°C to 35°C, and the value range of T 1B is 18°C to 28°C, which can be selected according to actual application scenarios.

[0096] Referring to FIG. 7, in some embodiments, the air conditioner control method is based on the specific process of each of the above embodiments, including but not limited to the following steps.

[0097] Step S710, after controlling the air conditioner to operate at the adjusted operating frequency for a first time length, determining the change of the current indoor temperature;

[0098] Step S720, when the current indoor temperature enters the temperature rising interval and is less than the third threshold temperature, repeating steps S750 to S770 every first time length to redetermine the operating frequency;

[0099] Step S730, when the current indoor temperature is greater than or equal to the third threshold temperature, switching the air conditioner from the energy-saving mode to the cooling mode to make the indoor temperature enter the temperature drop interval;

[0100] Step S740, when the indoor temperature drops to the fourth threshold temperature, restoring the cooling mode to the energy-saving mode and re-adjusting the operating frequency;

[0101] Step S750, when the outdoor temperature is greater than the first threshold temperature, taking the first preset frequency as the operating frequency;

[0102] Step S760, when the outdoor temperature is less than the second threshold temperature, taking the second preset frequency as the operating frequency;

[0103] Step S770, when the outdoor temperature is greater than or equal to the second threshold temperature and less than or equal to the first threshold temperature, adjusting the operating frequency to satisfy F0=(F1-F2)*(T1-T n2 ) / (T n1 -T n2 )+F2.

[0104] Referring to FIG. 8, in some embodiments, the step of re-adjusting the operating frequency can include, but is not limited to, step S610 and step S620.

[0105] Step S610, adjusting the operating frequency according to the current outdoor temperature to obtain the current operating frequency.

[0106] It can be understood that the specific process of adjusting the operating frequency according to the current outdoor temperature is as described in steps S210 to S230 above. In some specific examples, when T2≥43℃, the first preset frequency of 30Hz is taken as the current operating frequency of the energy-saving mode; when T2≤30℃, the second preset frequency of 5Hz is taken as the current operating frequency of the energy-saving mode; and when 30℃<T2<43℃, the operating frequency is calculated according to the formula F0=(F1-F2)*(T1-T n2 ) / (T n1 -T n2 )+F2, such as T2=38℃, the operating frequency F0=20.4Hz. Therefore, by performing the above steps S210 to S230 to dynamically adjust the operating frequency, the operating frequency can be continuously corrected to more reasonably operate the energy-saving mode.

[0107] Step S620, comparing the current operating frequency with the operating frequency adjusted last time, and taking the larger value of the current operating frequency and the operating frequency adjusted last time as the target operating frequency of the energy-saving mode.

[0108] After the operating frequency is adjusted through the above step S610, the current operating frequency is obtained, and then the current operating frequency is compared with the operating frequency adjusted last time, which can be understood as the last operating frequency before the current operating frequency is adjusted, wherein the current operating frequency is F n the last operating frequency is F n-1 In some embodiments, the current operating frequency F n is compared with the last operating frequency F n-1 The one with a larger value is taken as the target operating frequency, and the energy-saving mode is operated according to the target operating frequency.

[0109] When the outdoor temperature is at a high level and other factors, it is easy to cause the room heat load to be too high, thereby triggering the above steps S160 and S170, and the energy-saving mode is switched to the cooling mode for rapid cooling, and then the energy-saving mode is restored, that is, after the above steps enter the energy-saving mode, the indoor temperature is still prone to rising.

[0110] Therefore, when the indoor temperature enters the temperature rising interval A from the temperature falling interval B, in order to reduce the frequent switching between the temperature falling interval B and the temperature rising interval A, the current operating frequency F n is compared with the last operating frequency F n-1 After comparison, the larger value of the two is selected as the target operating frequency, so that the compressor is operated at a higher operating frequency, and the balance point of the cooling capacity output and the room heat load is more accurately determined when the indoor temperature enters the temperature rising interval A from the temperature falling interval B.

[0111] Referring to FIG. 9, in some embodiments, the step of comparing the current operating frequency with the operating frequency adjusted last time in step S620 can include but is not limited to step S621, step S622 and step S623.

[0112] Step S621, obtaining the operating frequency adjusted last time and recording it as a first operating frequency;

[0113] Step S622, determining a proportional coefficient according to the change that the indoor temperature enters from greater than or equal to a third threshold temperature to a fourth threshold temperature;

[0114] Step S623, obtaining a second operating frequency according to the product of the first operating frequency and the proportional coefficient, and determining the size of the current operating frequency and the second operating frequency.

[0115] When entering the temperature drop interval B from the temperature rise interval A, the indoor temperature starts to drop. The faster the indoor temperature drops, the higher the refrigeration output capacity. The change in the indoor temperature entering the temperature drop interval can reflect the speed of the change in the indoor temperature. A faster change indicates a faster drop in the indoor temperature, and a slower change indicates a slower drop in the indoor temperature. The change can be represented by a proportional coefficient K. The proportional coefficient K has a value range of 1 to 2, and the value of K is not limited to an integer. The faster the indoor temperature drops, the greater the value of the proportional coefficient K.

[0116] Therefore, the product of the last adjusted operating frequency and the proportional coefficient is the second operating frequency K*F n-1 That is, the last adjusted operating frequency is corrected according to the speed of the change in the indoor temperature in the temperature drop interval, and then the second operating frequency K*F n-1 is compared with the current operating frequency F n , and the larger one is taken as the target operating frequency.

[0117] Referring to FIG. 10, in some embodiments, determining the proportional coefficient according to the change in the indoor temperature entering the temperature drop interval in step S622 includes but is not limited to step S6221 and step S6222.

[0118] In step S6221, when the current indoor temperature is greater than or equal to the third threshold temperature, the change rate of the indoor temperature entering the refrigeration mode from the energy-saving mode and running for a second duration is obtained.

[0119] In step S6222, the proportional coefficient is calculated according to the following formula: K = [T1(t1)-T1(t0)] / T1(t0)+1, where K is the proportional coefficient, [T1(t1)-T1(t0)] / T1(t0) is the change rate, T1(t0) is the initial temperature of the indoor temperature entering the refrigeration mode from the energy-saving mode, and T1(t1) is the terminal temperature of the indoor temperature entering the refrigeration mode from the energy-saving mode and running for a second duration.

[0120] For example, the second time length is set as 30 minutes, when the indoor temperature T2≥32℃, the air conditioner is switched from the energy saving mode to the cooling mode, that is, from the temperature rising interval A to the temperature falling interval B, the proportional coefficient K is calculated by using the change rate of the indoor temperature in the first 30 minutes, for example, T1(t0)=T1(0)=32℃, which means that the initial temperature of the indoor temperature when the air conditioner is switched from the energy saving mode to the cooling mode is 32℃, T1(t1)=T1(30)=28℃, which means that the terminal temperature after running for 30 minutes is 28℃, the proportional coefficient K=1.125 is calculated according to the above formula, if the running frequency after the last adjustment is 15Hz, the second running frequency is calculated as 15Hz*1.125=16.8Hz.

[0121] It is to be noted that the indoor temperature is switched from the temperature falling interval B to the temperature rising interval A, the above steps S500 to S620 are executed, which is described below by taking a specific example.

[0122] Step S810, when T1>T 1A , the air conditioner is switched from the energy saving mode to the cooling mode, the temperature rising interval is switched to the temperature falling interval;

[0123] Step S820, when T1 1B , the cooling mode is switched to the energy saving mode;

[0124] Step S830, the running frequency is adjusted according to the current outdoor temperature, the current running frequency F n is calculated.

[0125] Step S840, the current running frequency F n is compared with the last adjusted running frequency K*F n-1 , the larger one is taken as the target running frequency of the energy saving mode.

[0126] It is to be noted that in step S830, the step of adjusting the running frequency according to the current outdoor temperature can be realized by executing the above steps S210 to S230, for example, when T2≥43℃, the first preset frequency 30Hz is taken as the current running frequency of the energy saving mode; when T2≤30℃, the second preset frequency 5Hz is taken as the current running frequency of the energy saving mode; when 30℃ n2 <T n1 <T n2 , the running frequency F0 is calculated according to the above formula, for example, when T2=38℃, the running frequency F0=20.4Hz.

[0127] Through steps S621 to S6222 above, the corrected operating frequency K*F from the previous adjustment can be obtained. n-1 Then, the current operating frequency F n Compared to the previous operating frequency K*F (after correction) n-1 By comparing the two values, the larger value is selected as the target operating frequency. By dynamically adjusting the operating frequency, it is ensured that the operating frequency is adjusted more appropriately each time the indoor temperature moves from the temperature drop range B to the temperature rise range A. This more accurately determines the balance point between cooling capacity output and room heat load, greatly reducing the situation where the indoor temperature exceeds the comfortable temperature range and effectively improving user comfort.

[0128] It should be noted that since the indoor temperature is at its initial state when the air conditioner is turned on, if the indoor temperature is lower than the set temperature at the time of startup, it indicates that the air conditioner has entered energy-saving mode for the first time. This can easily lead to a slow temperature rise, affecting user comfort. In some embodiments, when the air conditioner is turned on and enters energy-saving mode for the first time, the operating frequency of the air conditioner is adjusted according to the current outdoor temperature. This process can be achieved by executing steps S210 to S230 above. The adjusted operating frequency is obtained and used as the initial operating frequency of the energy-saving mode. The air conditioner operates at the initial operating frequency in energy-saving mode. Therefore, when entering energy-saving mode, the operating frequency of the energy-saving mode can be adjusted according to the outdoor temperature. Compared to starting the energy-saving mode at a lower fixed frequency, the embodiments of this application can adjust the operating frequency more flexibly, ensuring better cooling effect during startup and effectively improving user comfort.

[0129] Referring to FIG12, the air conditioner control method of this application is described with a specific overall example, which includes, but is not limited to, the following steps:

[0130] Step S1000: Activate energy-saving mode;

[0131] Step S1100: Determine the initial operating frequency according to steps S1200 to S1400, and determine whether the indoor temperature is greater than or equal to 28℃ after running for 30 minutes.

[0132] Step S1200: When the outdoor temperature is less than or equal to 30℃, the operating frequency is set to F2.

[0133] Step S1300: When the outdoor temperature is greater than or equal to 43℃, the operating frequency shall be set according to F1.

[0134] Step S1400: When the outdoor temperature is between 30℃ and 43℃, the operating frequency is calculated according to the following formula:

[0135] F0=(F1-F2)*(T1-Tn2 ) / (T n1 -T n2 )+F2;

[0136] Step S1500, when the indoor temperature is greater than or equal to 28℃, switching from the energy-saving mode to the refrigeration mode until the indoor temperature is less than 28℃, then performing step S1700;

[0137] Step S1600, when the indoor temperature is less than 28℃, then performing step S1700;

[0138] Step S1700, recalculating the operating frequency according to step S1200 to step S1400, and after continuing to operate for 30 minutes, performing step S1800;

[0139] Step S1800, when the indoor temperature is in the temperature rising interval A, then continuing to recalculate the operating frequency F n-1 every 30 minutes according to the above step S1200 to step S1400;

[0140] Step S1900, when the indoor temperature enters the temperature falling interval B, then switching from the energy-saving mode to the refrigeration mode until entering the temperature rising interval A;

[0141] Step S2000, when the indoor temperature enters the temperature rising interval A from the temperature falling interval B, recalculating the current operating frequency F n according to the above step S1200 to step S1400, and comparing the current operating frequency F n with the corrected last operating frequency K*F n-1 , and taking the larger value as the target operating frequency of the energy-saving mode.

[0142] The air conditioner control method of the embodiment of the present application can realize dynamic searching of the balance point of the refrigeration capacity output and the room heat load, effectively improving the user use comfort; and through dynamic adjustment of the operating frequency, the energy-saving mode operation is more reasonable, without frequent switching to the refrigeration mode, effectively reducing the indoor temperature rising speed, avoiding frequent switching to the refrigeration mode, and being beneficial to reducing the energy consumption.
