[0002] With the development of air-conditioning technology and the improvement of people's living standards, air conditioners have become essential household appliances. Air conditioners can provide various functions such as cooling, heating, air supply, and dehumidification to meet the different needs of users, which also makes the noise problem generated during the operation of the air conditioner more complicated and difficult to deal with. The relevant solution is to adjust the noise by setting the noise threshold, but this only considers the noise volume, and does not consider the impact of the noise quality. As a result, the noise volume may meet the nominal requirements, but the actual sound quality is very poor, which has a significant impact on the user's experience and comfort. In particular, the user's installation and use conditions are more stringent and complex than the development and testing conditions. Therefore, even if noise shielding is performed according to the test results during development, the user is still prone to poor noise quality and affect the user experience during actual use.

[0030] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0031] According to an embodiment of the present invention, a method for controlling air conditioning noise is provided, wherein the air conditioner includes an indoor unit and an outdoor unit, wherein the indoor unit has an internal fan, and the outdoor unit has a compressor. When a user uses the air conditioner, the noise level in the room will be affected by the noise generated by the air conditioner. Noise is generated during the rotation of the internal fan, and the noise generated when the compressor is running will be transmitted to the room through the pipeline, which not only increases the total value of indoor noise, but also may generate abnormal noise with special sound quality such as specific frequencies, resulting in a poor user experience. In addition to reducing the impact of the air conditioner on the total value of environmental noise, this solution also analyzes the sound quality of the noise generated by the air conditioner, and specifically adjusts the internal fan speed and compressor frequency, thereby improving the sound quality of the noise while ensuring that the air conditioner works stably and effectively, reducing the impact of air conditioning noise on users, improving the comfort of the indoor environment, and improving the user experience. Figure 1 The flowchart of an embodiment of the method of the present invention is shown in FIG. The air conditioner noise control method may include: steps S110 to S140.

[0032] In step S110, the indoor environmental noise when the air conditioner is turned off and the indoor environmental noise when the air conditioner is running are obtained, which are recorded as environmental noise and operating noise respectively; the indoor environmental temperature and the operating frequency of the outdoor unit are obtained.

[0033] The indoor unit is equipped with components such as microphones that can collect indoor environmental noise. When the air conditioner is in standby mode, the microphone will collect the indoor environmental noise in the current state and record it as environmental noise. After the air conditioner is turned on and reaches a stable state, the microphone will collect the indoor environmental noise in the current state again and record it as operating noise. Compared with environmental noise, operating noise includes the noise generated during the operation of the air conditioner, mainly the noise generated when the internal fan and compressor are running.

[0034] In some embodiments, the air conditioner has a sound collecting component; the sound collecting component is arranged at the air outlet or air duct outlet of the indoor unit, and can collect indoor environmental noise, so as to better characterize the noise characteristics transmitted to the indoor side by the air conditioner.

[0035] When the air conditioner is running, the large vibration generated by the outdoor unit is transmitted to the room through the connecting pipe or through the refrigerant, and resonates with the indoor unit structure. The sound collection component is set at the air outlet of the indoor unit to better identify the noise impact of the vibration on the indoor side. Optionally, the indoor environmental noise can be obtained in real time and displayed on the display screen of the indoor unit, so that users can better understand the noise level of the indoor environment.

[0036] In step S120, the environmental noise and the operating noise are analyzed respectively to obtain environmental noise analysis data and operating noise analysis data.

[0037] In some embodiments, the environmental noise analysis data includes the total environmental noise energy value; the operating noise analysis data includes the total operating noise energy value and the operating noise peak value. In step S120, the specific process of analyzing the environmental noise and the operating noise respectively to obtain the environmental noise analysis data and the operating noise analysis data includes: performing Fourier transform on the time domain data of the environmental noise to obtain the frequency domain data of the environmental noise; performing integral operation on the frequency domain data of the environmental noise to obtain the total environmental noise energy value; performing Fourier transform on the time domain data of the operating noise to obtain the frequency domain data of the operating noise; performing integral operation on the frequency domain data of the operating noise to obtain the total operating noise energy value; and determining the maximum value in the frequency domain data of the operating noise as the operating noise peak value.

[0038] Environmental noise and operating noise include the time domain data of the decibel value in the sound signal. After Fourier transform or fast Fourier transform of the time domain data, the frequency domain data is obtained. The frequency domain data represents the amplitude and phase information of different frequency components in the time domain data. In the frequency domain, the total noise energy is the total energy of all peaks in the full frequency range. The peak of operating noise is the frequency point with the highest energy in the frequency domain data of operating noise.

[0039] In step S130, target components for noise adjustment on the air conditioner are determined according to the environmental noise analysis data and the operating noise analysis data; the target components include at least the compressor and the indoor fan.

[0040] In some implementations, in step S130, the specific process of determining the target component for noise adjustment on the air conditioner according to the environmental noise analysis data and the operating noise analysis data includes: steps S210 to S230.

[0041] Step S210, determining the absolute value of the difference between the total energy value of the operating noise and the total energy value of the environmental noise.

[0042] Step S220: If the absolute value of the difference between the total energy value of the operating noise and the total energy value of the environmental noise is greater than or equal to a preset first difference, a target component for noise adjustment is determined according to the peak value of the operating noise.

[0043] Step S230, if the absolute value of the difference between the total operating noise energy value and the total ambient noise energy value is less than the preset first difference, and if the absolute value of the difference between the total operating noise energy value and the operating noise peak value is less than the preset second difference, the target component for noise adjustment is determined according to the operating noise peak value.

[0044] Total operating noise energy value P 运行 and the total environmental noise energy P环境 The difference between |P indicates the influence of the noise generated by the air conditioner operation on the indoor environmental noise. 运行 -P 环境 |≥preset first difference Δ1, indicating that the noise generated by the current air conditioner has a greater impact on the indoor environmental noise, and the air conditioner noise will significantly increase the indoor noise level. At this time, the noise generated by the air conditioner needs to be reduced. 运行 -P 环境 |<Δ1, indicating that the noise generated by the current air conditioner has little impact on the indoor environmental noise. 运行 The peak value of the operating noise P 峰值 The difference in value is used to analyze the impact of air conditioning noise on the sound quality of indoor environmental noise.

[0045] Specifically, P 运行 With P 峰值 The difference between |P indicates whether the noise peak is prominent. 运行 -P 峰值 |≥The preset second difference Δ2 indicates that the noise peak is not prominent in the current total value of the running noise energy, and the contribution of each peak to the total value of the running noise energy is relatively even, without an overly prominent peak. At this time, the noise is relatively soft to the ear, and there will be no obvious abnormal sound quality. 运行 -P 峰值 |<Δ2, which means that the noise peak is prominent under the current total noise energy value, and the peak contributes a lot to the total energy value, while other peaks contribute less. At this time, more obvious single-frequency noise may be generated, which will affect the sound quality of indoor ambient noise. For example, if the frequency of the noise peak is low, it will appear as a dull noise, and if the frequency is high, it will appear as a harsh noise. At this time, it is necessary to reduce the noise peak and reduce the proportion of the noise peak to the total energy value, so that the ambient noise can be heard relatively softly.

[0046] In some embodiments, in step S220 and step S230, the specific process of determining the target component for noise adjustment based on the operating noise peak includes: determining whether the frequency value corresponding to the operating noise peak is a multiple of the frequency of the internal fan, and determining whether the frequency value corresponding to the operating noise peak is a multiple of the frequency of the compressor; if the frequency value corresponding to the operating noise peak is a multiple of the frequency of the internal fan, determining that the target component for noise adjustment is the internal fan; if the frequency value corresponding to the operating noise peak is a multiple of the frequency of the compressor, determining that the target component for noise adjustment is the compressor.

[0047] In order to reduce the noise generated by the air conditioner and reduce the noise peak while ensuring the comfort of the indoor environment, it is necessary to determine the target component for adjustment based on the noise peak, whether it is the indoor fan or the compressor, and then adjust the noise level generated by the air conditioner by changing the indoor fan speed or the compressor frequency to improve the comfort of the indoor environment.

[0048] Peak value of operating noise P 峰值 The corresponding frequency value f 峰频 If it is a multiple of the internal fan frequency or the compressor frequency, P can be reduced by controlling the speed of the internal fan or the frequency of the compressor. 峰值 The size of the fan can reduce the noise level of the air conditioner and improve the sound quality of the noise. 内风机 =R*n / 60, R is the speed of the internal fan, n is the number of blades of the internal fan. 峰频 =i*f 内风机 (i=1, 2, 3……), then determine f 峰频 f 内风机 The target component for noise regulation is the internal fan. 峰频 =i*f 压缩机 , then determine f 峰频 f 压缩机 The target component for noise adjustment is the compressor.

[0049] Figure 3 FIG. 1 is a flow chart of another embodiment of the method for controlling air conditioner noise of the present invention. Figure 3 As shown, the method includes:

[0050] Step 1: When the air conditioning system is powered on and enters standby mode, obtain the total noise value P of the current ambient noise. 环境 After the user sends the power-on command, the total noise value p of the current ambient noise is obtained when the air conditioning system is running normally and stably. 运行 .

[0051] Step 2: Determine whether |P 运行 -P 环境 |<Δ1. If |P 运行 -P 环境 |≥Δ1, then proceed to step 3. If |P 运行 -P 环境 |<Δ1, then obtain the noise peak value P of the current environmental noise 峰值 , determine whether |P 运行 -P 峰值 |<Δ2. If |P 运行 -P 峰值 |≥Δ2, the air conditioner will keep running in the current state; if |P 运行 -P 峰值 |<Δ2, execute step 3.

[0052] Step 3: Get the peak noise value P of the current environment noise 峰值 The corresponding peak frequency f 峰频 , determine f 峰频 Is it the frequency multiple of the internal fan or the compressor? 峰频 If f is the multiple of the internal fan frequency, adjust the internal fan speed. 峰频 If it is a multiple of the compressor frequency, adjust the compressor frequency.

[0053] In step S140, the frequency of the compressor and / or the speed of the indoor fan are controlled according to the indoor ambient temperature and the operating frequency of the outdoor unit, thereby reducing the noise generated during the operation of the air conditioner and improving the sound quality of the noise.

[0054] In some embodiments, in step S140, the specific process of controlling the frequency of the compressor and / or the speed of the indoor fan according to the indoor ambient temperature and the operating frequency of the outdoor unit includes: when the target component for noise adjustment is the indoor fan, judging the absolute value of the difference between the indoor ambient temperature and the set temperature; if the absolute value of the difference between the indoor ambient temperature and the set temperature is greater than a first preset temperature difference, increasing the speed of the indoor fan; if the absolute value of the difference between the indoor ambient temperature and the set temperature is less than or equal to the first preset temperature difference, judging the difference between the operating frequency of the outdoor unit and the set operating frequency; if the difference between the operating frequency of the outdoor unit and the set operating frequency is greater than the first preset frequency difference, reducing the speed of the indoor fan; if the difference between the operating frequency of the outdoor unit and the set operating frequency is less than or equal to the first preset frequency difference, increasing the speed of the indoor fan.

[0055] When adjusting the speed of the indoor fan, first adjust the indoor ambient temperature T 环境 With the set temperature T 设定 The difference in value determines whether the indoor temperature meets the user's requirements, and then determines whether to increase or decrease the speed of the indoor fan. 环境 -T 设定 |>first preset temperature difference ΔT1, it means that the indoor ambient temperature has not reached the temperature range expected by the user. At this time, the speed of the indoor fan is increased. The frequency of the indoor fan is staggered with the frequency of the noise peak, the noise peak is reduced, and the user comfort is ensured while improving the sound quality of the noise. If |T 环境 -T 设定 |≤ΔT1, it means that the indoor ambient temperature is close to the temperature range expected by the user. At this time, the speed control strategy of the indoor fan is further determined according to the operating frequency of the outdoor unit.

[0056] Specifically, the operating frequency of the outdoor unit is 运行 With the set operating frequency f 设定The difference in value can determine whether the compressor is running at a high power. 运行 -f 设定 |>first preset frequency difference Δf1, it means that the compressor is running at a high power. At this time, reducing the speed of the indoor fan will have a relatively small impact on the indoor ambient temperature. 运行 -f 设定 |≤Δf1, it means that the compressor operates at a low power. In order to avoid a greater impact on the indoor ambient temperature, the speed of the indoor fan is increased.

[0057] Figure 4 FIG. 1 is a flow chart of an embodiment of the control logic of the internal fan speed. Figure 4 As shown, the method includes:

[0058] Step 11: Get the indoor ambient temperature T 环境 and user set temperature T 设定 , determine whether |T 环境 -T 设定 |≤Δ3. If |T 环境 -T 设定 |>Δ3, then increase the internal fan speed; if |T 环境 -T 设定 |≤Δ3, execute step 12.

[0059] Step 12: Get the outdoor unit operating frequency f 运行 and set frequency f 设定 , determine whether |f 运行 -f 设定 |≤Δ4. If |f 运行 -f 设定 |≤Δ4, increase the internal fan speed. If |f 运行 -f 设定 |>Δ4, the internal fan speed is reduced.

[0060] By determining whether to increase or decrease the speed of the internal fan according to the indoor ambient temperature and the operating frequency of the outdoor unit, the noise generated by the operation of the air conditioner can be reduced, the sound quality of the noise can be improved, and the user experience can be enhanced while ensuring a comfortable indoor ambient temperature.

[0061] In some embodiments, in step S140, the specific process of controlling the frequency of the compressor and / or the speed of the indoor fan according to the indoor ambient temperature and the operating frequency of the outdoor unit also includes: when the target component for noise adjustment is the compressor, judging the absolute value of the difference between the indoor ambient temperature and the set temperature; if the absolute value of the difference between the indoor ambient temperature and the set temperature is greater than the second preset temperature difference, increasing the frequency of the compressor; if the absolute value of the difference between the indoor ambient temperature and the set temperature is less than or equal to the second preset temperature difference, judging the difference between the operating frequency of the outdoor unit and the set operating frequency; if the difference between the operating frequency of the outdoor unit and the set operating frequency is greater than the second preset frequency difference, reducing the frequency of the compressor; if the difference between the operating frequency of the outdoor unit and the set operating frequency is less than or equal to the second preset frequency difference, increasing the frequency of the compressor.

[0062] When adjusting the compressor frequency, first adjust the indoor ambient temperature T 环境 With the set temperature T 设定 The difference between |T determines whether the indoor temperature meets the user's requirements, and then determines whether to increase or decrease the compressor frequency. 环境 -T 设定 |>the second preset temperature difference ΔT2, it means that the indoor ambient temperature has not reached the temperature range expected by the user. At this time, the operating frequency of the compressor is increased. The frequency of the compressor is staggered with the frequency of the noise peak, the noise peak is reduced, and the user comfort is ensured while improving the sound quality of the noise. If |T 环境 -T 设定 |≤ΔT1, it means that the indoor ambient temperature is close to the temperature range expected by the user. At this time, the compressor operating frequency control strategy is further determined according to the relationship between the operating frequency of the outdoor unit and the set operating frequency.

[0063] Specifically, the operating frequency of the outdoor unit is 运行 With the set operating frequency f 设定 The difference in value can determine whether the compressor is running at a high power. 运行 -f 设定 |>the second preset frequency difference Δf2, it means that the compressor operating power is high. At this time, reducing the compressor operating frequency will have a relatively small impact on the indoor ambient temperature. 运行 -f 设定 |≤Δf2, it means that the compressor operating power is low. In order to avoid a greater impact on the indoor ambient temperature, the compressor operating frequency is increased.

[0064] Figure 5 FIG. 1 is a flow chart of an embodiment of the control logic of the compressor frequency. Figure 5 As shown, the method includes:

[0065] Step 21, obtain the indoor ambient temperature T 环境 and user set temperature T 设定 , determine whether |T 环境 -T 设定 |≤Δ5. If |T 环境 -T 设定 |>Δ5, then increase the compressor frequency; if |T 环境 -T 设定 |≤Δ3, execute step 22.

[0066] Step 22: Get the outdoor unit operating frequency f 运行 and set frequency f 设定 , determine whether |f 运行 -f 设定 |≤Δ6. If |f 运行 -f 设定 |≤Δ6, then increase the compressor frequency. If |f 运行 -f 设定 |>Δ6 reduces or increases the compressor frequency.

[0067] By determining whether to increase or decrease the operating frequency of the compressor based on the indoor ambient temperature and the operating frequency of the outdoor unit, the noise generated by the air conditioner operation can be reduced, the sound quality of the noise can be improved, and the user experience can be enhanced while ensuring a comfortable indoor ambient temperature.

[0068] By adopting the technical solution of this embodiment, when the air conditioner is running, the ambient noise when the air conditioner is turned off and the operating noise when the air conditioner is running are analyzed to determine the target components for noise adjustment, including the compressor and the indoor fan; the indoor fan speed and the compressor frequency are controlled according to the indoor ambient temperature and the operating frequency of the outdoor unit. By analyzing the ambient noise and the operating noise to determine the target components for noise adjustment, and determining the adjustment strategy according to the indoor ambient temperature and the operating frequency of the compressor, the noise generated by the air conditioner is reduced while ensuring a comfortable indoor ambient temperature, the sound quality of the noise is improved, and the user experience is enhanced.

[0069] According to an embodiment of the present invention, there is also provided an air conditioner noise control device corresponding to the air conditioner noise control method. The air conditioner includes an indoor unit and an outdoor unit, the indoor unit having an internal fan, and the outdoor unit having a compressor. When a user uses the air conditioner, the noise level in the room will be affected by the noise generated by the air conditioner. Noise is generated during the rotation of the internal fan, and the noise generated when the compressor is running will be transmitted to the room through the pipeline, which not only increases the total value of the indoor noise, but also may generate abnormal noise with special sound quality such as specific frequencies, resulting in a poor user experience. In addition to reducing the impact of the air conditioner on the total value of environmental noise, this solution also analyzes the sound quality of the noise generated by the air conditioner, and specifically adjusts the internal fan speed and compressor frequency, thereby improving the sound quality of the noise while ensuring that the air conditioner works stably and effectively, reducing the impact of air conditioner noise on users, improving the comfort of the indoor environment, and improving the user experience. See. Figure 2 The structure diagram of an embodiment of the device of the present invention is shown in FIG. The air conditioner noise control device may include: an acquisition unit 102 and a control unit 104 .

[0070] The acquisition unit 102 is configured to acquire the indoor environmental noise when the air conditioner is turned off and the indoor environmental noise when the air conditioner is running, which are recorded as environmental noise and operating noise respectively; and acquire the indoor environmental temperature and the operating frequency of the outdoor unit. The specific functions and processing of the acquisition unit 102 refer to step S110.

[0071] The indoor unit is equipped with components such as microphones that can collect indoor environmental noise. When the air conditioner is in standby mode, the microphone will collect the indoor environmental noise in the current state and record it as environmental noise. After the air conditioner is turned on and reaches a stable state, the microphone will collect the indoor environmental noise in the current state again and record it as operating noise. Compared with environmental noise, operating noise includes the noise generated during the operation of the air conditioner, mainly the noise generated when the internal fan and compressor are running.

[0072] In some embodiments, the air conditioner has a sound collecting component; the sound collecting component is arranged at the air outlet or air duct outlet of the indoor unit, and can collect indoor environmental noise, so as to better characterize the noise characteristics transmitted to the indoor side by the air conditioner.

[0073] When the air conditioner is running, the large vibration generated by the outdoor unit is transmitted to the indoor through the connecting pipe or through the refrigerant, and resonates with the indoor unit structure. The sound collection component is set at the air outlet of the indoor unit to better identify the noise impact of vibration noise on the indoor side. Optionally, the indoor environmental noise can be obtained in real time and displayed on the display screen of the indoor unit, so that users can better understand the noise level of the indoor environment.

[0074] The control unit 104 is configured to analyze the environmental noise and the operating noise respectively to obtain environmental noise analysis data and operating noise analysis data. The specific functions and processing of the control unit 104 refer to step S120.

[0075] In some embodiments, the environmental noise analysis data includes the total environmental noise energy value; the operating noise analysis data includes the total operating noise energy value and the operating noise peak value. The control unit 104 analyzes the environmental noise and the operating noise respectively to obtain environmental noise analysis data and operating noise analysis data, including: performing Fourier transform on the time domain data of the environmental noise to obtain the frequency domain data of the environmental noise; performing integral operation on the frequency domain data of the environmental noise to obtain the total environmental noise energy value; performing Fourier transform on the time domain data of the operating noise to obtain the frequency domain data of the operating noise; performing integral operation on the frequency domain data of the operating noise to obtain the total operating noise energy value; and determining the maximum value in the frequency domain data of the operating noise as the operating noise peak value.

[0076] Environmental noise and operating noise include the time domain data of the decibel value in the sound signal. After Fourier transform or fast Fourier transform of the time domain data, the frequency domain data is obtained. The frequency domain data represents the amplitude and phase information of different frequency components in the time domain data. In the frequency domain, the total noise energy is the total energy of all peaks in the full frequency range. The peak of operating noise is the frequency point with the highest energy in the frequency domain data of operating noise.

[0077] The control unit 104 is further configured to determine a target component for noise adjustment on the air conditioner according to the environmental noise analysis data and the operating noise analysis data; the target component includes at least the compressor and the indoor fan. The specific functions and processing of the control unit 104 refer to step S130.

[0078] In some implementations, the control unit 104 determines the target component for noise adjustment on the air conditioner according to the environmental noise analysis data and the operating noise analysis data, including:

[0079] The control unit 104 is further configured to determine the absolute value of the difference between the total energy value of the operating noise and the total energy value of the environmental noise. The specific functions and processing of the control unit 104 refer to step S210.

[0080] The control unit 104 is further configured to determine a target component for noise adjustment according to the operating noise peak value if the absolute value of the difference between the total energy value of the operating noise and the total energy value of the ambient noise is greater than or equal to a preset first difference. The specific functions and processing of the control unit 104 refer to step S220.

[0081] The control unit 104 is further configured to determine the target component for noise adjustment according to the running noise peak value if the absolute value of the difference between the running noise energy total value and the environmental noise energy total value is less than a preset first difference, and if the absolute value of the difference between the running noise energy total value and the running noise peak value is less than a preset second difference. The specific functions and processing of the control unit 104 refer to step S230.

[0082] Total operating noise energy value P 运行 and the total environmental noise energy P 环境 The difference between |P indicates the influence of the noise generated by the air conditioner operation on the indoor environmental noise. 运行 -P 环境 |≥preset first difference Δ1, indicating that the noise generated by the current air conditioner has a greater impact on the indoor environmental noise, and the air conditioner noise will significantly increase the indoor noise level. At this time, the noise generated by the air conditioner needs to be reduced. 运行 -P 环境 |<Δ1, indicating that the noise generated by the current air conditioner has little impact on the indoor environmental noise. 运行 The peak value of the operating noise P 峰值 The difference in value is used to analyze the impact of air conditioning noise on the sound quality of indoor environmental noise.

[0083] Specifically, P 运行 With P 峰值 The difference between |P indicates whether the noise peak is prominent. 运行 -P 峰值 |≥The preset second difference Δ2 indicates that the noise peak is not prominent in the current total value of the running noise energy, and the contribution of each peak to the total value of the running noise energy is relatively even, without an overly prominent peak. At this time, the noise is relatively soft to the ear, and there will be no obvious abnormal sound quality. 运行 -P 峰值 |<Δ2, which means that the noise peak is prominent under the current total noise energy value, and the peak contributes a lot to the total energy value, while other peaks contribute less. At this time, more obvious single-frequency noise may be generated, which will affect the sound quality of indoor ambient noise. For example, if the frequency of the noise peak is low, it will appear as a dull noise, and if the frequency is high, it will appear as a harsh noise. At this time, it is necessary to reduce the noise peak and reduce the proportion of the noise peak to the total energy value, so that the ambient noise can be heard relatively softly.

[0084] In some embodiments, the control unit 104 determines the target component for noise adjustment based on the operating noise peak, including: determining whether the frequency value corresponding to the operating noise peak is a multiple of the frequency of the internal fan, and determining whether the frequency value corresponding to the operating noise peak is a multiple of the frequency of the compressor; if the frequency value corresponding to the operating noise peak is a multiple of the frequency of the internal fan, then determining that the target component for noise adjustment is the internal fan; if the frequency value corresponding to the operating noise peak is a multiple of the frequency of the compressor, then determining that the target component for noise adjustment is the compressor.

[0085] In order to reduce the noise generated by the air conditioner and reduce the noise peak while ensuring the comfort of the indoor environment, it is necessary to determine the target component for adjustment based on the noise peak, whether it is the indoor fan or the compressor, and then adjust the noise level generated by the air conditioner by changing the indoor fan speed or the compressor frequency to improve the comfort of the indoor environment.

[0086] Peak value of operating noise P 峰值 The corresponding frequency value f 峰频 If it is a multiple of the internal fan frequency or the compressor frequency, P can be reduced by controlling the speed of the internal fan or the frequency of the compressor. 峰值 The size of the fan can reduce the noise level of the air conditioner and improve the sound quality of the noise. 内风机 =R*n / 60, R is the speed of the internal fan, n is the number of blades of the internal fan. 峰频 =i*f 内风机 (i=1, 2, 3……), then determine f 峰频 f 内风机 The target component for noise regulation is the internal fan. 峰频 =i*f 压缩机 , then determine f 峰频 f 压缩机 The target component for noise adjustment is the compressor.

[0087] Figure 3 FIG. 1 is a flow chart of another embodiment of the method for controlling air conditioner noise of the present invention. Figure 3 As shown, the method includes:

[0088] Step 1: When the air conditioning system is powered on and enters standby mode, obtain the total noise value P of the current ambient noise. 环境 After the user sends the power-on command, the total noise value p of the current ambient noise is obtained when the air conditioning system is running normally and stably. 运行 .

[0089] Step 2: Determine whether |P 运行 -P 环境 |<Δ1. If |P 运行 -P环境 |≥Δ1, then proceed to step 3. If |P 运行 -P 环境 |<Δ1, then obtain the noise peak value P of the current environmental noise 峰值 , determine whether |P 运行 -P 峰值 |<Δ2. If |P 运行 -P 峰值 |≥Δ2, the air conditioner will keep running in the current state; if |P 运行 -P 峰值 |<Δ2, execute step 3.

[0090] Step 3: Get the peak noise value P of the current environment noise 峰值 The corresponding peak frequency f 峰频 , determine f 峰频 Is it the frequency multiple of the internal fan or the compressor? 峰频 If f is the multiple of the internal fan frequency, adjust the internal fan speed. 峰频 If it is a multiple of the compressor frequency, adjust the compressor frequency.

[0091] The control unit 104 is further configured to control the frequency of the compressor and / or the speed of the indoor fan according to the indoor ambient temperature and the operating frequency of the outdoor unit, thereby reducing the noise generated during the operation of the air conditioner and improving the sound quality of the noise. The specific functions and processing of the control unit 104 refer to step S140.

[0092] In some embodiments, the control unit 104 controls the frequency of the compressor and / or the speed of the indoor fan according to the indoor ambient temperature and the operating frequency of the outdoor unit, including: when the target component for noise adjustment is the indoor fan, judging the absolute value of the difference between the indoor ambient temperature and the set temperature; if the absolute value of the difference between the indoor ambient temperature and the set temperature is greater than a first preset temperature difference, increasing the speed of the indoor fan; if the absolute value of the difference between the indoor ambient temperature and the set temperature is less than or equal to the first preset temperature difference, judging the difference between the operating frequency of the outdoor unit and the set operating frequency; if the difference between the operating frequency of the outdoor unit and the set operating frequency is greater than the first preset frequency difference, reducing the speed of the indoor fan; if the difference between the operating frequency of the outdoor unit and the set operating frequency is less than or equal to the first preset frequency difference, increasing the speed of the indoor fan.

[0093] When adjusting the speed of the indoor fan, first adjust the indoor ambient temperature T 环境 With the set temperature T 设定 The difference in value determines whether the indoor temperature meets the user's requirements, and then determines whether to increase or decrease the speed of the indoor fan. 环境 -T 设定|>first preset temperature difference ΔT1, it means that the indoor ambient temperature has not reached the temperature range expected by the user. At this time, the speed of the indoor fan is increased. The frequency of the indoor fan is staggered with the frequency of the noise peak, the noise peak is reduced, and the user comfort is ensured while improving the sound quality of the noise. If |T 环境 -T 设定 |≤ΔT1, it means that the indoor ambient temperature is close to the temperature range expected by the user. At this time, the speed control strategy of the indoor fan is further determined according to the operating frequency of the outdoor unit.

[0094] Specifically, the operating frequency of the outdoor unit is 运行 With the set operating frequency f 设定 The difference in value can determine whether the compressor is running at a high power. 运行 -f 设定 |>first preset frequency difference Δf1, it means that the compressor is running at a high power. At this time, reducing the speed of the indoor fan will have a relatively small impact on the indoor ambient temperature. 运行 -f 设定 |≤Δf1, it means that the compressor operates at a low power. In order to avoid a greater impact on the indoor ambient temperature, the speed of the indoor fan is increased.

[0095] Figure 4 FIG. 1 is a flow chart of an embodiment of the control logic of the internal fan speed. Figure 4 As shown, the method includes:

[0096] Step 11: Get the indoor ambient temperature T 环境 and user set temperature T 设定 , determine whether |T 环境 -T 设定 |≤Δ3. If |T 环境 -T 设定 |>Δ3, then increase the internal fan speed; if |T 环境 -T 设定 |≤Δ3, execute step 12.

[0097] Step 12: Get the outdoor unit operating frequency f 运行 and set frequency f 设定 , determine whether |f 运行 -f 设定 |≤Δ4. If |f 运行 -f 设定 |≤Δ4, increase the internal fan speed. If |f 运行 -f 设定 |>Δ4, the internal fan speed is reduced.

[0098] By determining whether to increase or decrease the speed of the internal fan according to the indoor ambient temperature and the operating frequency of the outdoor unit, the noise generated by the operation of the air conditioner can be reduced, the sound quality of the noise can be improved, and the user experience can be enhanced while ensuring a comfortable indoor ambient temperature.

[0099] In some embodiments, the control unit 104 controls the frequency of the compressor and / or the speed of the indoor fan according to the indoor ambient temperature and the operating frequency of the outdoor unit, and also includes: when the target component for noise adjustment is the compressor, judging the absolute value of the difference between the indoor ambient temperature and the set temperature; if the absolute value of the difference between the indoor ambient temperature and the set temperature is greater than a second preset temperature difference, increasing the frequency of the compressor; if the absolute value of the difference between the indoor ambient temperature and the set temperature is less than or equal to the second preset temperature difference, judging the difference between the operating frequency of the outdoor unit and the set operating frequency; if the difference between the operating frequency of the outdoor unit and the set operating frequency is greater than the second preset frequency difference, reducing the frequency of the compressor; if the difference between the operating frequency of the outdoor unit and the set operating frequency is less than or equal to the second preset frequency difference, increasing the frequency of the compressor.

[0100] When adjusting the compressor frequency, first adjust the indoor ambient temperature T 环境 With the set temperature T 设定 The difference in value determines whether the indoor temperature meets the user's requirements, and then determines whether to increase or decrease the operating frequency of the compressor. 环境 -T 设定 |>the second preset temperature difference ΔT2, it means that the indoor ambient temperature has not reached the temperature range expected by the user. At this time, the operating frequency of the compressor is increased. The frequency of the compressor is staggered with the frequency of the noise peak, the noise peak is reduced, and the user comfort is ensured while improving the sound quality of the noise. If |T 环境 -T 设定 |≤ΔT1, it means that the indoor ambient temperature is close to the temperature range expected by the user. At this time, the compressor operating frequency control strategy is further determined according to the relationship between the operating frequency of the outdoor unit and the set operating frequency.

[0101] Specifically, the operating frequency of the outdoor unit is 运行 With the set operating frequency f 设定 The difference in value can determine whether the compressor is running at a high power. 运行 -f 设定 |>the second preset frequency difference Δf2, it means that the compressor operating power is high. At this time, reducing the compressor operating frequency will have a relatively small impact on the indoor ambient temperature. 运行 -f 设定|≤Δf2, it means that the compressor operating power is low. In order to avoid a greater impact on the indoor ambient temperature, the compressor operating frequency is increased.

[0102] Figure 5 FIG. 1 is a flow chart of an embodiment of the control logic of the compressor frequency. Figure 5 As shown, the method includes:

[0103] Step 21, obtain the indoor ambient temperature T 环境 and user set temperature T 设定 , determine whether |T 环境 -T 设定 |≤Δ5. If |T 环境 -T 设定 |>Δ5, then increase the compressor frequency; if |T 环境 -T 设定 |≤Δ3, execute step 22.

[0104] Step 22: Get the outdoor unit operating frequency f 运行 and set frequency f 设定 , determine whether |f 运行 -f 设定 |≤Δ6. If |f 运行 -f 设定 |≤Δ6, then increase the compressor frequency. If |f 运行 -f 设定 |>Δ6 reduces or increases the compressor frequency.

[0105] By determining whether to increase or decrease the operating frequency of the compressor based on the indoor ambient temperature and the operating frequency of the compressor, the noise generated by the air conditioner operation can be reduced, the sound quality of the noise can be improved, and the user experience can be enhanced while ensuring a comfortable indoor ambient temperature.
