[0049] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0050] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0051] Figure 1 This is an air conditioning control method provided by this embodiment, referring to Figure 1 , the method may include the following steps:

[0052] Step 101, obtaining the operating frequency and operating time of the compressor of the air conditioner.

[0053] In the embodiment of the present application, the operation frequency and operation time of the compressor of the air conditioner can be obtained periodically in step 101. Optionally, the acquisition period can be 120 seconds (s), the acquisition period can also be 60s, and the acquisition period of the operation frequency and the operation time can also be different.

[0054] In the embodiment of the present application, the running time in step 101 may be the running time for maintaining the current running frequency, or the running time may be the running time after the air conditioner is started.

[0055] In some embodiments, in step 101, the operating frequency of the compressor of the air conditioner can also be obtained through a preset operating frequency calculation formula.

[0056] Exemplarily, the operating frequency calculation formula is as follows:

[0057] F 运行 =Δn×ΔT×F 设定

[0058] Among them, F 运行 represents the operating frequency of the compressor, Δn is the fan speed parameter calculated based on the current speed of the outdoor fan, ΔT is the heating temperature parameter calculated based on the indoor temperature during heating operation, or the cooling temperature parameter calculated based on the indoor temperature during cooling operation, F 设定 Indicates the set frequency.

[0059] Step 102: When the operating frequency and the operating time meet the stable operating conditions, the outdoor ambient temperature of the external fan of the air conditioner is obtained.

[0060] In the embodiment of the present application, in step 102, the outdoor ambient temperature can be obtained by a temperature detection unit pre-set at a preset position of the outdoor fan.

[0061] In some embodiments, the stable operation condition includes: the frequency difference between the operation frequency of the current cycle and the operation frequency of the previous cycle is less than or equal to a frequency difference threshold, and the operation time is greater than or equal to a preset duration.

[0062] Optionally, the frequency difference threshold may be 4 Hertz (Hz).

[0063] Exemplarily, the acquisition cycle of the operating frequency and the operating time is 120 seconds, and judging whether the operating frequency and the operating time meet the stable operation condition may include: recording the operating frequency once every 120 seconds and calculating the frequency difference ΔF between the operating frequency of the current cycle and the operating frequency of the previous cycle, and if the frequency difference ΔF is less than or equal to 4 Hz within every 120 seconds and the operating time t of the operating frequency is maintained ≥ 120 seconds, then determining that the operating frequency and the operating time meet the stable operation condition. That is, at this time, the compressor of the air conditioner is in a stable operation stage.

[0064] In this way, by setting the trigger condition of the stable operation condition, the outdoor ambient temperature can be obtained when the compressor of the air conditioner is in a stable operation stage, which not only improves the accuracy of the determined resonant speed, but also reduces meaningless calculation processes.

[0065] In some embodiments, after step 102 , the air conditioning control method may further include: controlling the air conditioning to enter an external fan adaptive frequency mode, where the external fan adaptive frequency mode is used to execute the following steps 103 to 105 .

[0066] Step 103: determining the resonant speed of the outdoor fan of the air conditioner according to the operating frequency of the air conditioner.

[0067] It is understandable that when the variable frequency air conditioner is in operation, resonance noise is likely to be generated when the frequency of the outdoor fan is close to that of the compressor. In the embodiment of the present application, the speed at which the outdoor fan is likely to generate resonance noise is referred to as the "resonance speed". The resonance speed may be a certain speed value or a certain speed range, which is not specifically limited in the present embodiment.

[0068] In some embodiments, step 103 may include: determining the resonant speed of the outdoor fan of the air conditioner according to the operating frequency and the hardware parameters of the outdoor fan, wherein the hardware parameters of the outdoor fan may include the fundamental frequency coefficient of the air conditioner and the number of blades of the outdoor fan.

[0069] In other embodiments, step 103 may also include: determining the resonant speed of the outdoor fan of the air conditioner according to the correspondence between the preset operating frequency and the speed range that produces the resonance effect, and the above correspondence may be pre-stored in the memory of the air conditioner.

[0070] Step 104: Determine a first initial speed range of the outdoor fan according to the outdoor ambient temperature.

[0071] Among them, the initial speed ranges corresponding to different outdoor ambient temperatures are different.

[0072] In the embodiment of the present application, the initial speed range corresponding to different outdoor ambient temperatures can be pre-set.

[0073] It can be understood that the first initial speed range is a speed range calculated in order to ensure the cooling effect or heating effect of the air conditioner without considering whether resonance occurs.

[0074] In some embodiments, step 104 may include: determining a first initial speed range of the outdoor fan according to a correspondence between the outdoor ambient temperature and a preset outdoor ambient temperature and an initial speed range.

[0075] Optionally, the correspondence between the outdoor ambient temperature and the initial rotational speed range includes a correspondence between the outdoor ambient temperature and the initial rotational speed range in a cooling mode and / or a heating mode.

[0076] For example, the corresponding relationship between the outdoor ambient temperature and the initial speed range in the heating mode is shown in Table 1:

[0077] Table 1

[0078] Outdoor temperature (Celsius) Initial speed range (rpm) Less than or equal to 25℃ 300 to 450 Greater than 25℃ and less than or equal to 35℃ 451 to 600 Greater than 35℃ and less than or equal to 43℃ 601 to 750 More than 43℃ 751 to 860

[0079] Similarly, the corresponding relationship between the outdoor ambient temperature and the initial speed range in cooling mode is shown in Table 2:

[0081] Table 2

[0082] Outdoor temperature (Celsius) Initial speed range (rpm) Less than or equal to -5℃ 751 to 860 Greater than -5℃ and less than or equal to 7℃ 601 to 750 Greater than 7℃ and less than or equal to 13℃ 451 to 600 More than 20℃ 300 to 450

[0083] Step 105 : determining a target speed of the air conditioner according to the resonance speed and the first initial speed range, and controlling the air conditioner to operate at the target speed.

[0084] In the embodiment of the present application, the target rotation speed is obtained by shielding the resonant rotation speed in the first initial rotation speed range.

[0085] In some embodiments, step 105 may include using the speed intervals other than the resonance speed interval in the first initial speed range as the non-resonance speed interval of the air conditioner; and using any speed value in the non-resonance speed interval as the target speed of the air conditioner.

[0086] In other embodiments, step 105 may also include: determining the resonant speed range of the air conditioner based on the resonant speed and a preset error value; using the speed range other than the resonant speed range in the first initial speed range as the non-resonant speed range of the air conditioner; and using any speed value in the non-resonant speed range as the target speed of the air conditioner.

[0087] For example, the resonant speed may be 400 revolutions per minute (rpm), and the preset error value may be 10 rpm. Based on the resonant speed and the preset error value, determining the resonant speed range of the air conditioner may include: taking 400±10 rpm as the resonant speed range of the air conditioner; that is, the resonant speed range of the air conditioner is 390 rpm to 410 rpm; and taking any speed between 390 rpm and 410 rpm as the target speed of the air conditioner.

[0088] In summary, in this embodiment, when the air conditioner is running stably, the speed of the outdoor fan that is prone to resonance is first determined by the operating frequency of the air conditioner, and then the first initial speed range corresponding to different gears is determined in advance by the outdoor ambient temperature. Finally, according to the speed range that is prone to resonance and the initial speed range, the target speed is obtained and the air conditioner is controlled to run at this speed. Since the speed of the outdoor fan that is prone to resonance is shielded in the first initial speed range, the frequencies of the compressor and the outdoor fan will not be similar, and resonance noise will not be generated. In addition, the obtained target speed does not contain a large number of continuous speed shielding points, and running at the target speed will not affect the load of the air conditioner. In other words, the method provided by the present application can not only avoid the occurrence of resonance and achieve the purpose of reducing the noise of the outdoor fan, but also improve the continuity and stability of the frequency output of the compressor, thereby ensuring the stable operation of the air conditioner and further ensuring the cooling and heating effects of the air conditioner.

[0089] Figure 2 is a flowchart of the specific steps of an air conditioning control method provided in an embodiment of the present application, refer to Figure 2 , the air conditioning control method may include the following steps:

[0090] Step 201, obtaining the operating frequency and operating time of the compressor of the air conditioner.

[0091] The method of this step has been described in the aforementioned step 101 and will not be repeated here.

[0092] In some embodiments, after step 201, the air conditioning control method may further include the following steps:

[0093] When the operating frequency and operating time do not meet the stable operating conditions, the air conditioner is controlled to operate at a preset speed.

[0094] In a possible implementation, when the operating frequency difference is greater than the frequency difference threshold and the operating frequency is greater than or equal to the upper frequency limit, the first rotation speed is used as the target rotation speed of the air conditioner.

[0095] Optionally, the upper frequency limit may be 35 Hz, and the first rotational speed may be the maximum rotational speed of the air conditioner.

[0096] For example, the first rotation speed may be 860 rpm.

[0097] In another possible implementation, when the operating frequency difference is greater than the frequency threshold and the operating frequency is less than the frequency upper limit, the second rotation speed is used as the target rotation speed of the air conditioner.

[0098] It is understandable that when the operating frequency and operating time do not meet the stable operating conditions, it means that the air conditioner has just been started or is in other unstable stages. At this time, it runs at a preset speed and waits for the air conditioner to enter a stable operating stage.

[0099] By using the above-mentioned technical means and setting the trigger condition of stable operation condition, the outdoor ambient temperature can be obtained when the compressor of the air conditioner is in a stable operation stage, which not only improves the accuracy of the determined resonant speed, but also reduces meaningless calculation processes.

[0100] Step 202: When the operating frequency and the operating time meet the stable operating conditions, the outdoor ambient temperature of the external fan of the air conditioner is obtained.

[0101] The method of this step has been described in the aforementioned step 102 and will not be repeated here.

[0102] Step 203, determining the resonant rotation speed according to the operating frequency, the fundamental frequency coefficient, the number of blades and the preset coefficient.

[0103] In the embodiment of the present application, the fundamental frequency refers to the lowest frequency generated by an object when it vibrates, and the fundamental frequency coefficient refers to the coefficient between the lowest frequency of resonance generated by the outdoor fan and the operating frequency of the compressor.

[0104] For example, the base frequency coefficient may be 1, 2, or 2 / 3.

[0105] In the embodiment of the present application, the number of blades refers to the number of blades of the outdoor fan, for example, the number of blades may be 3, 6, etc.

[0106] In the embodiments of the present application, the preset coefficients are coefficients calibrated based on a large number of experiments in order to reduce calculation errors.

[0107] For example, the preset coefficient may be 60.

[0108] In some embodiments, the resonant speed may be determined by a preset resonant speed calculation formula.

[0109] Exemplarily, the resonant speed calculation formula is as follows:

[0110]

[0111] In the above formula, F 运行 represents the operating frequency of the compressor, X represents the number of blades of the outdoor fan, and p n Indicates the fundamental frequency coefficient of the air conditioner.

[0112] Through the above technical means, the resonant speed of the outdoor fan is calculated based on the operating frequency of the compressor, which is beneficial to shielding the resonant speed of the outdoor fan and thus avoiding the generation of noise.

[0113] Step 204: Determine a first initial speed range of the outdoor fan according to the outdoor ambient temperature.

[0114] The method of this step has been described in the aforementioned step 204 and will not be repeated here.

[0115] For example, step 204 may include the following sub-steps:

[0116] Sub-step A1, determining a first wind speed level of the air conditioner according to the outdoor ambient temperature and the first corresponding relationship.

[0117] The first corresponding relationship is the corresponding relationship between different outdoor ambient temperatures and different wind speed levels.

[0118] In this embodiment, the first corresponding relationship includes the corresponding relationship between the outdoor ambient temperature and the wind speed level in the cooling mode and the heating mode.

[0119] Exemplarily, the first corresponding relationship is shown in Table 3:

[0120] Table 3

[0121]

[0122] Sub-step A2, determining a first initial speed range of the outdoor fan according to the first wind speed level and the second corresponding relationship.

[0123] The second corresponding relationship is the corresponding relationship between different wind speed gears and different initial rotation speed ranges.

[0124] In this embodiment, the second corresponding relationship includes the corresponding relationship between the wind speed level and the initial rotation speed range in the cooling mode and the heating mode.

[0125] Exemplarily, the second corresponding relationship is shown in Table 4:

[0126] Table 4

[0127]

[0128] Through the above technical means, the wind speed level adopted by the air conditioner is first determined according to the outdoor ambient temperature, and then the initial speed range is determined according to the wind speed level adopted by the air conditioner, which is conducive to the subsequent shielding of the resonant speed in the initial speed range, thereby reducing the generation of resonant noise.

[0129] Step 205: The speed interval except the resonance speed in the first initial speed range is used as the non-resonance speed of the air conditioner.

[0130] In the embodiment of the present application, the non-resonant speed of the air conditioner can be obtained by shielding the resonant speed in the first initial speed range.

[0131] In some embodiments, step 205 may include: determining the resonant speed of the air conditioner according to the resonant speed and a preset error value; and using the speed range other than the resonant speed in the first initial speed range as the non-resonant speed of the air conditioner.

[0132] For example, the resonant speed range may be 400 revolutions per minute (rpm), and the preset error value may be 10 rpm. Based on the resonant speed range and the preset error value, determining the resonant speed range of the air conditioner may include: taking 400±10 rpm as the resonant speed range of the air conditioner; that is, the resonant speed range of the air conditioner is 390 rpm to 410 rpm.

[0133] Step 206 , taking the maximum value of the non-resonance speed as the target speed of the air conditioner and controlling the air conditioner to operate at the target speed.

[0134] Through the above-mentioned technical means, not only can the resonance be avoided and the purpose of outdoor fan noise reduction be achieved, but also the maximum value of non-resonance speed can be adopted to improve the operating efficiency of the air conditioner, thereby improving the efficiency of air conditioning heating or cooling and ensuring the cooling and heating effects of the air conditioner.

[0135] In some embodiments, after step 206, the air conditioning control method may further include the following sub-steps:

[0136] Sub-step B1, obtaining the indoor ambient temperature of the indoor unit of the air conditioner.

[0137] In the embodiment of the present application, the indoor ambient temperature can be obtained by a temperature detection unit pre-set at a preset position of the indoor unit.

[0138] In an embodiment of the present application, the indoor ambient temperature may be acquired periodically, wherein the acquisition period of the indoor ambient temperature may be the same as the acquisition period of the outdoor ambient temperature, or the acquisition period of the indoor ambient temperature may be different from the acquisition period of the outdoor ambient temperature.

[0139] For example, the acquisition period of the indoor ambient temperature may be 60 seconds.

[0140] Sub-step B2, determining the indoor ambient temperature difference between the indoor ambient temperature of the current cycle and the indoor ambient temperature of the previous cycle.

[0141] In the embodiment of the present application, if the air conditioner is in heating mode, the indoor environment temperature difference represents the cooling rate of the indoor environment, and if the air conditioner is in cooling mode, the indoor environment temperature difference represents the heating rate of the indoor environment.

[0142] Exemplarily, when the air conditioner is controlled to run at the maximum value of the non-resonance speed range, the indoor ambient temperature difference is calculated every 60 seconds.

[0143] Sub-step B31, when the indoor ambient temperature difference is greater than or equal to the first temperature difference threshold, controlling the air conditioner to reduce the current speed by a preset speed value.

[0144] In an embodiment of the present application, the first temperature difference threshold in the heating mode and in the heating mode may be different, and the first temperature difference threshold in the heating mode and in the heating mode may also be the same; the first temperature difference threshold may be a specific value, and the first temperature difference threshold may also be a temperature change value.

[0145] In the embodiment of the present application, the preset speed value can be obtained based on a large number of experimental calibrations.

[0146] For example, the first temperature difference threshold may be 5° C., and the preset rotation speed value may be 20 rpm.

[0147] It is understandable that when the indoor ambient temperature difference is greater than or equal to the first temperature difference threshold, it means that the current operating frequency can meet the required heating or cooling effect. However, from the perspective of saving energy consumption, the current speed can be appropriately reduced.

[0148] Through the above technical means, under the premise of ensuring the heating or cooling effect, when the indoor ambient temperature difference is greater than or equal to the first temperature difference threshold, the air conditioner is controlled to reduce the current speed to a preset speed value, which can save energy and extend the service life of the air conditioner.

[0149] Sub-step B32, when the indoor ambient temperature difference is less than the first temperature difference threshold, changing the first wind speed gear to the second wind speed gear; wherein, when the air conditioner is in cooling mode, the second wind speed gear is greater than the first wind speed gear, and when the air conditioner is in heating mode, the second wind speed gear is less than the first wind speed gear;

[0150] According to the second wind speed level, a second initial speed range of the outdoor fan is determined.

[0151] The target speed of the air conditioner is determined according to the resonance speed and the second initial speed range.

[0152] It is understandable that when the indoor ambient temperature difference is less than the first temperature difference threshold, it means that the current operating frequency cannot meet the required heating or cooling effect, and therefore, the wind force needs to be increased to improve the current rotation speed.

[0153] In the embodiment of the present application, the second initial speed range of the outdoor fan can be determined based on the second corresponding relationship and according to the second wind speed level.

[0154] In one possible implementation, determining the target speed of the air conditioner based on the resonant speed and the second initial speed range may include: redetermining the non-resonant speed range of the air conditioner based on the resonant speed and the second initial speed range; using the maximum value of the redetermined non-resonant speed range as the target speed of the air conditioner and controlling the air conditioner to operate at the target speed.

[0155] In a possible implementation, after the first wind speed level is changed to the second wind speed level, the air conditioning control method may further include: recalculating the indoor ambient temperature difference; when the indoor ambient temperature difference is less than the first temperature difference threshold, changing the second wind speed level to the third wind speed level; wherein, when the air conditioner is in cooling mode, the third wind speed level is greater than the second wind speed level, and when the air conditioner is in heating mode, the third wind speed level is less than the second wind speed level. Similarly, the indoor ambient temperature is continuously obtained until the wind speed level is changed to the fourth wind speed level.

[0156] In a possible implementation, after sub-step B2, the air conditioning control method may further include: calculating the temperature change rate of the indoor ambient temperature based on the indoor ambient temperature difference and the acquisition period of the indoor ambient temperature; when the temperature change rate is greater than or equal to the speed threshold, controlling the air conditioner to reduce the current speed by a preset speed value; when the temperature change rate is less than the speed threshold, changing the first wind speed gear to the second wind speed gear.

[0157] For example, the speed threshold may be 2 degrees Celsius per minute (° C. / min).

[0158] Through the above technical means, when the indoor ambient temperature difference is less than the first temperature difference threshold, in order to ensure the heating or cooling effect, the target speed of the air conditioner is re-determined, and adaptive adjustment of the air conditioner is achieved, providing users with a more intelligent usage experience.

[0159] In some embodiments, after step 206, the air conditioning control method may further include the following steps:

[0160] Acquiring a heat dissipation temperature of a heat dissipation detection unit, wherein the heat dissipation detection unit is arranged on an air conditioner radiator;

[0161] Determine the heat dissipation temperature difference between the heat dissipation temperature of the current cycle and the heat dissipation temperature of the previous cycle;

[0162] When the heat dissipation temperature is greater than the preset heat dissipation temperature threshold and the heat dissipation temperature difference is less than or equal to the second temperature difference threshold, the air conditioner is controlled to operate according to the ambient temperature.

[0163] In the embodiment of the present application, the heat dissipation temperature threshold may be 60° C., and the second temperature difference threshold may be 2° C.

[0164] In a possible implementation, the ambient temperature and controlling the operation of the air conditioner include: determining a first initial speed range of the outdoor fan according to the outdoor ambient temperature; and controlling the air conditioner to operate at a minimum value of the first initial speed range.

[0165] It can be understood that when the heat dissipation temperature is greater than the preset temperature threshold and the heat dissipation temperature difference is less than or equal to the second temperature difference threshold, it means that the temperature of the radiator is high and the high temperature has lasted for a period of time. At this time, the current speed of the air conditioner cannot meet the heat dissipation requirements of the air conditioner. In order to ensure the safety of the air conditioner equipment, lowering the radiator temperature is the primary requirement. At this time, the problem of resonance noise is not considered, and the air conditioner operation is controlled only at the minimum value of the speed range corresponding to the ambient temperature.

[0166] Through the above technical means, when the radiator of the air-conditioning equipment is overheated, the current speed can be reduced in time, thereby ensuring the safe operation of the air-conditioning.

[0167] In summary, in this embodiment, when the air conditioner is operating stably, first, the rotation speed range where the outdoor fan is prone to resonance is determined through the operating frequency, fundamental frequency coefficient, number of blades, and preset coefficient. Then, based on the outdoor ambient temperature, the wind force gear adopted by the air conditioner is obtained. Next, the initial rotation speed range corresponding to different preset wind force gears is determined. Finally, according to the rotation speed range where resonance is prone to occur and the initial rotation speed range, the non-resonant rotation speed interval of the air conditioner is obtained, and the air conditioner is controlled to operate at the maximum value of the non-resonant rotation speed interval. Since the non-resonant rotation speed interval that does not include the rotation speed at which the outdoor fan is prone to resonance is determined first, the frequencies of the compressor and the outdoor fan will not be close to each other, and thus resonance noise will not be generated. Moreover, the target rotation speed is the maximum value of the resonant rotation speed interval, and operating at a higher rotation speed can improve the heating or cooling efficiency of the air conditioner. That is to say, the method provided in this embodiment can not only avoid resonance and achieve the purpose of reducing noise of the outdoor fan, but also improve the efficiency of the frequency output of the compressor, ensure the efficient operation of the air conditioner, and further ensure the refrigeration and heating effects of the air conditioner.

[0168] Figure 3 is a specific step flowchart of another air conditioner control method provided by an embodiment of the present application. Referring to Figure 3 , taking the air conditioner in the cooling mode as an example, the above air conditioner control method may include the following steps:

[0172] Step 3041, operate at the highest rotation speed corresponding to the wind force gear K4.

[0173] In this embodiment, operating at the highest rotation speed corresponding to a certain wind force gear may include: based on the second correspondence relationship, determining the initial rotation speed range of the outdoor fan according to the wind force gear; operating at the highest rotation speed in the initial rotation speed range.

[0174] Step 3042, operate at the highest rotation speed corresponding to the wind force gear K2.

[0175] Step 305, calculate the resonant rotation speed.

[0176] In this embodiment, the method for calculating the resonant rotation speed is similar to Step 203 and will not be elaborated here.

[0177] Step 306, detect the outdoor ambient temperature T外环 .

[0178] Step 3071, determine whether T 外环 ≤T1. If yes, execute step 3081; if no, execute step 3072.

[0179] In this embodiment, T1 may be 5°C.

[0180] Step 3072, determine whether T1 <T 外环 ≤T2. If yes, execute step 3082; if no, execute step 3073.

[0181] In this embodiment, T2 may be 35°C.

[0182] Step 3073, determine whether T2 <T 外环 ≤T3. If yes, execute step 3083; if no, execute step 3074.

[0183] In this embodiment, T3 may be 43°C.

[0184] Step 3074, determine whether T 外环 >T3. If yes, execute step 3084; if no, end.

[0185] Step 3081, the wind speed level enters K1.

[0186] Step 3082, the wind speed level enters K2.

[0187] Step 3083, the wind speed level enters K3.

[0188] Step 3084, the wind speed level enters K4.

[0189] Step 309: operating at the highest speed in the non-resonant speed range corresponding to the wind power gear.

[0190] In this embodiment, the method for determining the non-resonance speed range is similar to step 205 and will not be described in detail here.

[0191] Step 310, record the indoor ambient temperature every 60 seconds and calculate the indoor ambient temperature cooling rate V.

[0192] In this embodiment, the cooling speed V is calculated by the indoor ambient temperature difference between the indoor ambient temperature of the current cycle and the indoor ambient temperature of the previous cycle.

[0193] Step 311, determine whether V ≥ V set If yes, execute step 3121; if no, execute step 3122.

[0194] In this embodiment, V set The speed threshold indicating the cooling speed, for example, V set It can be 2°C / min.

[0195] Step 3121, reduce the current rotation speed by 20 rpm.

[0196] Step 3122, wind speed level enters K N+1 .

[0197] In this embodiment, the wind speed level enters K N+1 Indicates increasing the current wind speed by one level.

[0198] Step 313, record the heat dissipation temperature every 60 seconds and calculate the heat dissipation temperature difference.

[0199] Step 314 , determining whether the heat dissipation temperature difference is ≥ 2° C. If yes, executing step 315 ; if not, returning to executing step 310 .

[0200] Step 315, exit the adaptive frequency control mode of the outdoor fan.

[0201] In this embodiment, exiting the adaptive frequency control mode of the outdoor fan means that only the outdoor ambient temperature is used to determine the target speed of the outdoor fan without considering the noise reduction issue.

[0202] In summary, in this embodiment, when the air conditioner is running stably, the speed of the outdoor fan that is prone to resonance is first determined by the operating frequency of the air conditioner, and then the first initial speed range corresponding to different gears is determined in advance by the outdoor ambient temperature. Finally, according to the speed range that is prone to resonance and the initial speed range, the target speed is obtained and the air conditioner is controlled to run at this speed. Since the speed of the outdoor fan that is prone to resonance is shielded in the first initial speed range, the frequencies of the compressor and the outdoor fan will not be similar, and resonance noise will not be generated. In addition, the obtained target speed does not contain a large number of continuous speed shielding points, and running at the target speed will not affect the load of the air conditioner. In other words, the method provided by the present application can not only avoid the occurrence of resonance and achieve the purpose of reducing the noise of the outdoor fan, but also improve the continuity and stability of the frequency output of the compressor, thereby ensuring the stable operation of the air conditioner and further ensuring the cooling and heating effects of the air conditioner.
