[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0025] Silencing components reduce the sound energy radiated outwards by relying on abrupt changes in the cross-section or length of the component's pipes to alter impedance during sound propagation. This results in sound energy reflection, interference, and resonant sound absorption, thus achieving noise reduction. Based on the aforementioned principles, this invention adjusts the length of the silencer component according to refrigerant temperature, pressure, and the frequency of abnormal noise. This allows for the silencing of different frequencies of operating noise generated by the air conditioner, thereby improving user experience and satisfaction.

[0026] Figure 1 This is one of the flowcharts illustrating the personalized noise reduction control method for air conditioners provided by this invention.

[0027] The following will combine Figure 1 The process of personalized noise reduction control methods for air conditioners is explained.

[0028] In an exemplary embodiment of the present invention, the air conditioner may include an exhaust pipe connected in series with a silencer assembly, wherein the silencer assembly is expandable, thereby ensuring that the silencer assembly can extend or retract. Combined with Figure 1 As can be seen, the personalized noise reduction control method for air conditioners may include steps 110 and 120, which will be described in detail below.

[0029] In step 110, the refrigerant temperature and pressure value in the exhaust pipe are obtained.

[0030] In step 120, when abnormal noise is detected during the operation of the air conditioner, the length of the noise-reducing component is adjusted in a personalized manner based on the refrigerant temperature and pressure value, and the noise is eliminated based on the noise-reducing component after the length adjustment.

[0031] In one embodiment, after the air conditioner has been running stably for a preset time according to a preset operating mode, the refrigerant temperature T and the pressure P in the exhaust pipe can be obtained. It should be noted that the exhaust pipe mainly contains refrigerant; therefore, the pressure value in the exhaust pipe can be considered primarily related to the pressure of refrigerant formation.

[0032] Furthermore, if abnormal noise is detected during the operation of the air conditioner, the length of the muffler component can be adjusted based on the refrigerant temperature T and pressure value P to cause a sudden change in the length of the muffler component. This causes a change in impedance during the propagation of the abnormal noise, resulting in sound energy reflection, interference, and resonance absorption. This reduces the sound energy radiated outward by the muffler component after the length adjustment, thereby eliminating the abnormal noise.

[0033] The abnormal noise can be a sound with a frequency value exceeding a frequency threshold. This abnormal noise can be operating noise generated by the air conditioner during operation, including refrigerant noise. The frequency value of the abnormal noise can change during the operation of the air conditioner. In another embodiment, the frequency value of the abnormal noise can be obtained from a sound sensor installed on the air conditioner. In this embodiment, since the abnormal noise has different frequency values, a silencing component with a personalized adjustable length is used to eliminate abnormal noises with different frequency values, thereby achieving noise reduction processing for different frequencies of operating noise generated by the air conditioner, and improving the user experience and satisfaction.

[0034] This invention provides a personalized noise reduction control method for air conditioners. The air conditioner includes an exhaust pipe connected in series with a retractable silencer assembly. The method includes: acquiring the refrigerant temperature and pressure value within the exhaust pipe; and, upon detecting abnormal noise generated by the air conditioner during operation, adjusting the length of the silencer assembly based on the refrigerant temperature and pressure value, and then eliminating the abnormal noise based on the adjusted length of the silencer assembly. Since abnormal noises have different frequency values, eliminating noises with different frequency values ​​through a personalized, length-adjustable silencer assembly achieves noise reduction for different frequencies of operating noise generated by the air conditioner, thereby improving user experience and satisfaction.

[0035] Figure 2 This is a schematic diagram of the process for customizing the length of the silencer component based on refrigerant temperature and pressure values, as provided by the present invention.

[0036] To further introduce the personalized noise reduction control method for air conditioners provided by this invention, the following will be combined with... Figure 2 Please provide an explanation.

[0037] In an exemplary embodiment of the present invention, combined with Figure 2 As can be seen, based on the refrigerant temperature and pressure value, the personalized adjustment of the length of the muffler component may include steps 210 to 230, which will be described in detail below.

[0038] In step 210, the frequency value of the abnormal sound is obtained.

[0039] In step 220, the speed of sound of the refrigerant is determined based on the refrigerant temperature and pressure values.

[0040] In step 230, the target length of the silencing component is determined based on the heterophonic frequency value and the sound velocity of the refrigerant, and the length of the silencing component is adjusted individually based on the target length.

[0041] In one embodiment, the abnormal sound frequency value H can be obtained. This abnormal sound frequency value can be obtained using a sound sensor installed on the air conditioner. Further, the sound velocity V of the refrigerant in the exhaust pipe can be determined based on the refrigerant temperature T and pressure P. Then, based on the obtained abnormal sound frequency value H and the refrigerant sound velocity V, a target length L of the muffler assembly is determined, and the length of the muffler assembly is adjusted based on the target length L to effectively eliminate the abnormal sound. It should be noted that the target length is different for different abnormal sound frequency values ​​H and different refrigerant sound velocities V; therefore, the length of the muffler assembly can be individually adjusted based on the target length L to effectively eliminate abnormal sounds of different frequencies.

[0042] In yet another exemplary embodiment of the present invention, the target length of the silencing component is determined based on the heterophonic frequency value and the sound velocity of the refrigerant, which can be achieved in the following manner:

[0043] The target length of the noise reduction component is determined by the quotient of the sound velocity and the different frequency values ​​of the sound at a preset multiple.

[0044] In one embodiment, the target length of the noise reduction assembly can be determined using formula (1):

[0045] L=V\aH (1)

[0046] Where L represents the target length; a represents the preset multiple; V represents the speed of sound of the refrigerant; and H represents the heterophonic frequency value. a can be adjusted according to actual conditions, for example, it can be 4. In this embodiment, a is not specifically limited.

[0047] It should be noted that, in this embodiment, since the abnormal noise includes refrigerant noise and other operating noise generated by the air conditioner during operation, when abnormal noise is detected, the target length L of the noise-reducing component is determined based on the refrigerant sound velocity V and the abnormal noise frequency value H. Changing the length of the noise-reducing component abruptly to the target length L can simultaneously eliminate the operating noise generated by the air conditioner during operation, including refrigerant noise. Through this embodiment, noise reduction processing can be achieved for operating noise of different frequencies generated by the air conditioner, thereby improving the user experience and satisfaction.

[0048] In yet another exemplary embodiment of the present invention, the personalized adjustment of the length of the noise-reducing component based on the target length can be achieved in the following manner:

[0049] If the target length is greater than the initial length of the muffler assembly, the muffler assembly is extended based on its scalability so that the length of the extended muffler assembly is equal to the target length.

[0050] When the target length is less than the initial length of the muffler assembly, the muffler assembly is controlled to shrink based on its scalability so that the length of the shrunken muffler assembly is equal to the target length.

[0051] In one example, when it is determined that the target length is greater than the initial length of the muffler component, the scalability of the muffler component is used to control the muffler component to be extended so that the length of the extended muffler component is equal to the target length, thereby enabling the adjusted length of the muffler component to effectively eliminate abnormal noise.

[0052] In another example, when it is determined that the target length is less than the initial length of the muffler component, the scalability of the muffler component is used to control the muffler component to shrink so that the length of the shrunken muffler component is equal to the target length, thereby enabling the adjusted length of the muffler component to effectively eliminate abnormal noise.

[0053] In yet another exemplary embodiment of the present invention, the speed of sound of the refrigerant can be determined based on the refrigerant temperature and pressure values ​​in the following manner:

[0054] Based on the refrigerant temperature and pressure values, the speed of sound of the refrigerant corresponding to the refrigerant temperature and pressure values ​​is determined through a pre-maintained mapping table. The mapping table includes the correspondence between the refrigerant temperature and pressure values ​​and the speed of sound of the refrigerant.

[0055] In one embodiment, the velocity of sound of the refrigerant corresponding to its temperature and pressure values ​​can be determined using a pre-maintained mapping table. In another embodiment, the correspondence between the refrigerant temperature and pressure values ​​and the velocity of sound of the refrigerant in the mapping table can be determined using refrigerant property calculation formulas.

[0056] The mapping table can also be determined in other ways, which will be discussed below. Figure 3 The process of determining the mapping table is explained.

[0057] Figure 3 This is a flowchart illustrating the process of determining the mapping table provided by the present invention.

[0058] In an exemplary embodiment of the present invention, combined with Figure 3 As can be seen, determining the mapping table may include steps 310 to 330, and each step will be described below.

[0059] In step 310, based on the historical refrigerant temperature, historical pressure value and historical sound velocity of the refrigerant, the initial correspondence between the refrigerant temperature, pressure value and sound velocity of the refrigerant is determined;

[0060] In step 320, the initial correspondence is updated based on the latest obtained refrigerant temperature, the latest obtained pressure value, and the latest obtained refrigerant sound velocity to obtain the updated correspondence.

[0061] In step 330, a mapping table is determined based on the updated correspondence.

[0062] In one embodiment, an initial correspondence between refrigerant temperature, pressure, and sound velocity can be determined based on previously acquired historical refrigerant temperatures, pressure values, and sound velocities. Since new refrigerant temperatures, pressure values, and sound velocities will occur during application, to ensure the accuracy of the correspondence in the mapping table, the initial correspondence needs to be updated in real-time based on the latest acquired refrigerant temperatures, pressure values, and sound velocities, resulting in an updated correspondence. The mapping table is then determined based on this updated correspondence. Through this embodiment, the correspondence in the mapping table is updated each time a new refrigerant temperature, pressure value, and sound velocity are generated, ensuring the accuracy of the sound velocity determined based on the mapping table, refrigerant temperature, and pressure values. This lays the foundation for obtaining the accurate target length of the silencer assembly, thus more effectively eliminating abnormal noise generated by the air conditioner during operation.

[0063] Figure 4 This is the second flowchart of the personalized noise reduction control method for air conditioners provided by the present invention.

[0064] To further introduce the personalized noise reduction control method for air conditioners provided by this invention, the following will be combined with... Figure 4 Please provide an explanation.

[0065] In an exemplary embodiment of the present invention, combined with Figure 4As can be seen, the personalized noise reduction control method for air conditioners may include steps 410 to 440. Steps 410 and 420 are the same as or similar to steps 110 and 120. For specific implementation methods and beneficial effects, please refer to the previous description. They will not be repeated in this embodiment. Steps 430 and 440 will be introduced below.

[0066] In step 430, the air conditioner continues to be monitored for any abnormal noises during operation.

[0067] In step 440, if abnormal noise is detected in the air conditioner during operation, the step of individually adjusting the length of the silencer assembly based on the refrigerant temperature and pressure value is repeated until the air conditioner no longer produces abnormal noise during operation.

[0068] In one embodiment, after the air conditioner has been running for a preset period of time until its power stabilizes, such as 10 minutes, the compressor discharge temperature T and pressure P (corresponding to the refrigerant temperature and pressure in the discharge pipe) can be read. Based on the discharge temperature T and pressure P, the refrigerant sound velocity V can be calculated using refrigerant property calculation formulas for different refrigerants. Furthermore, a sound sensor can be used to detect the presence of an abnormal noise frequency H. When frequency H is greater than or equal to a frequency threshold, it indicates that an abnormal noise frequency H has been detected. If no abnormal noise frequency H is detected, it means that the length of the silencer assembly is appropriate and does not require adjustment.

[0069] In another example, if the frequency H of the abnormal noise is detected, the target length L1 of the muffler assembly can be determined based on the quotient of the refrigerant sound velocity V and the frequency H of the abnormal noise at a preset multiple. The length L of the muffler assembly is then adjusted based on the target length L1. If L1 is greater than L, the muffler assembly is extended based on its scalability control, so that the extended length L of the muffler assembly is equal to the target length L1. If L1 is less than L, the muffler assembly is contracted based on its scalability control, so that the contracted length L of the muffler assembly is equal to the target length L1.

[0070] In another embodiment, the presence of the abnormal noise frequency H can be detected again using a sound sensor. If the frequency H is not present, it indicates that the length of the noise-absorbing component has been adjusted correctly. If the frequency H is present, it indicates that the length of the noise-absorbing component has not been adjusted correctly and needs further adjustment. In this embodiment, the length of the noise-absorbing component can be automatically adjusted according to actual conditions, such as the frequency value of the abnormal noise, thereby eliminating abnormal noise of any frequency. This is suitable for different cooling and heating conditions, and can significantly improve the user experience and satisfaction.

[0071] As described above, the personalized noise reduction control method for air conditioners provided by this invention includes an air conditioner with an exhaust pipe connected in series with a retractable silencer assembly. The method includes: acquiring the refrigerant temperature and pressure value within the exhaust pipe; and, upon detecting abnormal noise generated by the air conditioner during operation, adjusting the length of the silencer assembly based on the refrigerant temperature and pressure value, and eliminating the abnormal noise based on the length-adjusted silencer assembly. Since abnormal noises have different frequency values, eliminating abnormal noises with different frequency values ​​through a personalized length-adjustable silencer assembly achieves noise reduction processing for different frequencies of operating noise generated by the air conditioner, thereby improving user experience and satisfaction.

[0072] Based on the same concept, the present invention also provides a personalized noise reduction control device for air conditioners.

[0080] Obtain the frequency value of the unusual sound;

[0081] The speed of sound of the refrigerant is determined based on the refrigerant temperature and pressure values.

[0082] Based on the different frequency values ​​and the speed of sound of the refrigerant, the target length of the silencing component is determined, and the length of the silencing component is adjusted in a personalized manner based on the target length.

[0083] In an exemplary embodiment of the present invention, the processing module 520 may implement personalized adjustment of the length of the muffler component based on the target length in the following manner:

[0084] If the target length is greater than the initial length of the muffler assembly, the muffler assembly is extended based on its scalability so that the length of the extended muffler assembly is equal to the target length.

[0085] When the target length is less than the initial length of the muffler assembly, the muffler assembly is controlled to shrink based on its scalability so that the length of the shrunken muffler assembly is equal to the target length.

[0093] Based on the updated correspondence, the mapping table is determined.

[0094] In an exemplary embodiment of the present invention, the processing module 520 may further be configured to:

[0095] Continue to monitor the air conditioner for any unusual noises during operation;

[0096] If abnormal noise is detected in the air conditioner during operation, repeat the step of adjusting the length of the silencer component based on the refrigerant temperature and pressure value until the air conditioner no longer produces abnormal noise during operation.
