Description

[0001] The present invention relates to the technical field of air conditioners, and particularly to a control method for an air conditioner unit and an air conditioner unit. Background Art

[0002] In the related art, in order to avoid a large noise generated by an air conditioner unit during user use and affect the user experience, a noise test is usually performed on the outdoor unit of the air conditioner unit, and the air conditioner unit can be sold only when it is determined that the maximum intensity noise generated during the operation of the outdoor unit is lower than the noise intensity threshold (a noise intensity higher than the noise intensity threshold has a greater stimulus to the human ear). However, the air conditioner unit is usually used in noisy environments such as shopping malls and office buildings, so that the ambient noise of the environment where the outdoor unit is actually used is greater than the ambient noise of the environment where it is tested. As a result, when the air conditioner unit is actually used, the noise generated when the compressor of the outdoor unit operates at a certain operating frequency still exceeds the noise intensity threshold after being superimposed with the ambient noise, affecting the user experience. Summary of the Invention

[0003] In view of the above problems, the present invention is proposed to provide a control method for a compressor and an air conditioner unit that can overcome or at least partially solve the above problems. The control method of the compressor of the present invention can avoid excessive noise during the operation of the outdoor unit, thereby improving the user experience.

[0004] Specifically, the present invention discloses a control method for an air conditioner unit.

[0005] The control method for the air conditioner unit of the present invention includes: controlling the compressor to operate at a plurality of operating frequencies respectively, and detecting the superimposed noise value corresponding to each of the operating frequencies; wherein, the superimposed noise value reflects the noise intensity after the operating noise of the compressor and the ambient noise of the target space are superimposed; determining at least one of the superimposed noise values that is greater than or equal to the noise threshold from the plurality of superimposed noise values, and recording it as the target noise value; determining at least one of the operating frequencies corresponding to the target noise value, and recording it as the target operating frequency; generating a frequency hopping parameter according to the target operating frequency, and the frequency hopping parameter describes the operating frequency to be skipped during the operation state of the compressor.

[0006] In some embodiments, the step of controlling the compressor to operate at multiple operating frequencies respectively and detecting the superimposed noise value corresponding to each operating frequency includes: increasing the operating frequency of the compressor based on a frequency adjustment strategy; the frequency adjustment strategy is a strategy for adjusting the operating frequency executed after detecting the operating frequency of the compressor and the corresponding superimposed noise value; wherein, the frequency adjustment strategy includes controlling the operating frequency of the compressor to increase by a first preset value; obtaining the operating frequency of the compressor after the frequency increase and the corresponding superimposed noise value. In some embodiments, before the step of obtaining the operating frequency of the compressor after the frequency increase and the corresponding superimposed noise value, it further includes: controlling the operating frequency of the compressor to remain unchanged within a first preset time period.

[0007] In some embodiments, before the step of obtaining the operating frequency of the compressor after the frequency increase and the corresponding superimposed noise value, it further includes: judging whether the operating parameters of the compressor are less than or equal to a second preset value every first preset time period; if so, executing the step of obtaining the current operating frequency of the compressor and the corresponding superimposed noise value.

[0008] In some embodiments, the step of obtaining the operating frequency of the compressor after the frequency increase and the corresponding superimposed noise value further includes: obtaining the noise intensity value reflecting the superimposed operating noise of the compressor and the environmental noise of the target space every set time value within a second preset time period to obtain a plurality of noise intensity values; wherein, the second preset time period has at least two set time values; taking the maximum value among the plurality of noise intensity values as the superimposed noise value corresponding to the operating frequency of the compressor after the frequency increase.

[0009] In some embodiments, before the step of controlling the compressor to operate at multiple operating frequencies respectively, it further includes: controlling the indoor unit to enter the high wind mode; wherein, the high wind mode includes: controlling the fan of the indoor unit to operate; controlling the air deflector at the air outlet of the indoor unit to open a preset opening degree to block the air flow blown out from the air outlet.

[0010] In some embodiments, before the step of controlling the compressor to operate at multiple operating frequencies respectively, it further includes: adjusting the frequency limit of the compressor to the rated maximum frequency limit.

[0011] In some embodiments, before the step of controlling the compressor to operate at multiple operating frequencies respectively, it further includes: in response to a startup instruction, judging whether the air conditioner unit is starting up for the first time; if so, executing the step of controlling the compressor to operate at multiple operating frequencies respectively.

[0012] In some embodiments, the noise threshold is the intensity threshold of the noise.

[0013] The air conditioner unit of the present invention includes a controller, and the controller includes a memory, a processor, and a machine-executable program stored on the memory and running on the processor. When the processor executes the machine-executable program, the control method described in any one of the above is implemented.

[0014] The control method of the air conditioner unit according to the embodiment of the present invention controls the compressor of the outdoor unit to operate at multiple operating frequencies respectively, and records the corresponding superimposed noise values when the compressor operates at multiple operating frequencies. Then, by judging each of the multiple superimposed noise values one by one, the target operating frequency corresponding to the superimposed noise value greater than the noise threshold among the multiple superimposed noise values is detected, and further, the compressor of the outdoor unit skips the target operating frequency during normal operation. Since the superimposed noise value detected from the target space will not be greater than the noise threshold when the compressor of the outdoor unit operates at an operating frequency other than the target operating frequency, the noise during the operation of the air conditioner unit is small, thereby improving the user experience.

In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0029] The air conditioner unit of the embodiment of the present invention includes an indoor unit and an outdoor unit 100, wherein the indoor unit and the outdoor unit 100 are connected. The outdoor unit 100 includes a compressor 120. The compressor 120 of the outdoor unit 100 is used to compress the refrigerant into a high-temperature and high-pressure gas during the refrigeration process, and then send it into the condenser for cooling.

[0030] During the operation of the compressor 120 of the outdoor unit 100, certain noise will be generated. When the compressor 120 of the outdoor unit 100 operates at certain frequencies, the noise generated and the ambient noise may overlap and exceed the sound intensity threshold. That is to say, the noise of the outdoor unit 100 during operation at this frequency is too large, which will affect the user experience.

[0031] The control method of the air conditioner unit of the embodiment of the present invention can avoid excessive noise during the operation of the outdoor unit 100, thereby improving the user experience.

[0032] The following describes the control method of the air conditioner unit of the embodiment of the present invention with reference to the accompanying drawings.

[0033] As Figure 1 shown, the control method of the air conditioner unit of the embodiment of the present invention includes the following steps:

[0034] S120. Control the compressor 120 to operate at multiple operating frequencies respectively, and detect the superimposed noise value corresponding to each operating frequency. That is to say, control the compressor 120 to operate at multiple different operating frequencies respectively, detect and record the superimposed noise value corresponding to the compressor 120 at each operating frequency, so as to obtain multiple superimposed noise values.

[0035] Among them, the superimposed noise value reflects the noise intensity after the operating noise of the compressor 120 and the ambient noise of the target space are superimposed. That is to say, the superimposed noise value does not reflect the noise value generated when the compressor 120 operates, but reflects the noise value in the target space when the compressor 120 operates in the target space.

[0036] S200. Determine at least one superimposed noise value greater than or equal to the noise threshold from multiple superimposed noise values, and denote it as the target noise value; determine at least one operating frequency corresponding to the target noise value, and denote it as the target operating frequency. That is to say, judge whether each of the multiple superimposed noise values is greater than or equal to the noise threshold, denote the superimposed noise value greater than or equal to the noise threshold as the target noise value, and denote the operating frequency corresponding to the target noise value as the target operating frequency.

[0037] It can be understood that when the compressor 120 operates at the target operating frequency, the combined noise intensity of the operating noise of the compressor 120 and the ambient noise in the target space will be greater than or equal to the noise threshold, affecting the user experience.

[0038] S300. Generate a frequency hopping parameter according to the target operating frequency. The frequency hopping parameter describes the operating frequency to be skipped during the operation of the compressor 120. That is to say, when the air conditioner unit operates normally in the embodiment of the present invention, the compressor 120 of the outdoor unit 100 operates at an operating frequency other than the target operating frequency.

[0039] Compared with the related art, the control method of the air conditioner unit in the embodiment of the present invention controls the compressor 120 of the outdoor unit 100 to operate at multiple operating frequencies respectively, and records the corresponding superimposed noise values when the compressor 120 operates at multiple operating frequencies. Then, by judging each of the multiple superimposed noise values one by one, the target operating frequency corresponding to the superimposed noise value greater than the noise threshold among the multiple superimposed noise values is detected, so that the compressor 120 of the outdoor unit 100 skips the target operating frequency during normal operation. Since the superimposed noise value detected from the target space will not be greater than the noise threshold when the compressor 120 of the outdoor unit 100 operates at an operating frequency other than the target operating frequency, the noise during the operation of the air conditioner unit is small, thus improving the user experience.

[0040] In some optional embodiments, a noise spectrum analyzer 110 is provided on the outdoor unit 100. Among them, the noise spectrum analyzer 110 can detect the noise in the surrounding environment to obtain the corresponding superimposed noise values when the compressor 120 of the outdoor unit 100 operates at multiple operating frequencies.

[0041] In some optional embodiments, the noise threshold is the intensity threshold of the noise.

[0042] In some embodiments, as Figure 2 shown, step S120, the step of controlling the compressor 120 to operate at multiple operating frequencies respectively, further includes the following steps:

[0043] S121. Increase the operating frequency of the compressor 120 based on the frequency adjustment strategy; the frequency adjustment strategy is a strategy for adjusting the operating frequency executed after detecting the operating frequency of the compressor 120 and the corresponding superimposed noise value; wherein, the frequency adjustment strategy includes controlling the operating frequency of the compressor 120 to increase by a first preset value.

[0044] S123. Obtain the operating frequency of the compressor 120 after frequency increase and the corresponding superimposed noise value.

[0045] That is to say, by controlling the frequency increase of the compressor 120, the compressor 120 operates at multiple operating frequencies. And after the operating frequency of the compressor 120 increases by the first preset value, obtain the operating frequency of the compressor 120 after frequency increase and the corresponding superimposed noise value, and after obtaining the operating frequency and the superimposed noise value, control the compressor 120 to continue to increase the frequency until the operating frequency of the compressor 120 rises to the maximum frequency limit allowed.

[0046] Since when the compressor 120 increases the frequency, its operating frequency increases by the first preset value each time, enabling the compressor 120 to increase the frequency evenly. When the compressor 120 executes step S120, the working condition of the compressor 120 conforms to its working condition during normal operation, so that the sound emitted by the compressor 120 during operation is more in line with the sound emitted during normal operation, and thus the detected superimposed noise value is more representative.

[0047] Preferably, the first preset value is 1 Hz. That is to say, when the compressor 120 increases the frequency, its operating frequency increases by 1 Hz each time.

[0048] In some embodiments, as Figure 2 shown, before step S123, obtaining the operating frequency of the compressor 120 after frequency increase and the corresponding superimposed noise value, the following steps are further included:

[0049] S122. Control the operating frequency of the compressor 120 to remain unchanged within a first preset time period. That is to say, after the compressor 120 increases the frequency and before obtaining the operating frequency of the compressor 120 after frequency increase and the corresponding superimposed noise value, control the compressor 120 to maintain the operating frequency after frequency increase for a certain period of time.

[0050] After the compressor 120 increases its frequency, the compressor 120 is maintained at the increased operating frequency for a certain period of time, so that after the compressor 120 operates stably, the superimposed noise value corresponding to the compressor 120 at this operating frequency is obtained. In other words, after the compressor 120 is stabilized, the superimposed noise value corresponding to the compressor 120 at this operating frequency is obtained, so that the obtained superimposed noise value can more truly reflect the noise situation in the target space when the compressor 120 operates at this operating frequency, and avoid the impact on the detection result of the superimposed noise value caused by the fluctuation of the operation of the compressor 120 during the transient process of frequency increase.

[0051] Optionally, the first preset time period is 2 min.

[0052] In some other embodiments, as Figure 3 shown, before step S123, obtaining the operating frequency of the compressor 120 after frequency increase and the corresponding superimposed noise value, the following steps are further included:

[0053] At every interval of the first preset time period, it is judged whether the operating parameters of the compressor 120 are less than or equal to the second preset value.

[0054] If so, the steps of obtaining the current operating frequency of the compressor 120 and the corresponding superimposed noise value are executed.

[0055] That is to say, before obtaining the operating frequency of the compressor 120 after frequency increase and the corresponding superimposed noise value, first control the compressor 120 to maintain the increased operating frequency for a certain period of time to make the operating state of the compressor 120 tend to be stable, and then detect the operating parameters of the compressor 120 to determine whether the compressor 120 is in a stable operating state.

[0056] When the operating parameters of the compressor 120 meet the preset conditions, that is, the compressor 120 is in a stable operating state, the steps of obtaining the current operating frequency of the compressor 120 and the corresponding superimposed noise value are executed; when the operating parameters of the compressor 120 do not meet the preset conditions, that is, the compressor 120 is not yet in a stable operating state, the steps of obtaining the current operating frequency of the compressor 120 and the corresponding superimposed noise value are not executed, the compressor 120 continues to maintain the current operating frequency to operate, and the operating parameters of the compressor 120 are detected again after the first preset time, and it is judged again whether the preset conditions are met until the operating parameters of the compressor 120 meet the preset conditions.

[0057] That is to say, it is determined whether the compressor 120 reaches a stable operating state through the operating parameters of the compressor 120, so as to ensure that the superimposed noise value corresponding to the compressor 120 at this operating frequency is obtained after the compressor 120 is stable, thereby further avoiding the impact on the detection result of the superimposed noise value caused by the fluctuation of the operation of the compressor 120 during the transient process of frequency increase.

[0058] For example, the operating parameter of the compressor 120 is the current change rate of the compressor 120, and the second preset value is 0.5 A / min. When the current change rate of the compressor 120 is less than 0.5 A / min, the steps of obtaining the current operating frequency of the compressor 120 and the corresponding superimposed noise value are executed.

[0059] In some other embodiments, as Figure 3 shown, step S123, obtaining the operating frequency after the compressor 120 increases its frequency and the corresponding superimposed noise value further includes the following steps:

[0060] S126. Obtain the noise intensity values after superimposing the operating noise of the compressor 120 and the ambient noise of the target space at intervals of a set duration value within a second preset time period to obtain a plurality of noise intensity values; wherein, the second preset time period has at least two set duration values. That is to say, a plurality of noise intensity values are obtained within the second preset time period.

[0061] S127. Take the maximum value among the plurality of noise intensity values as the superimposed noise value corresponding to the operating frequency after the compressor 120 increases its frequency.

[0062] It can be understood that, on the premise of ensuring that the compressor 120 is already in a stable operating state, if the maximum value among the plurality of noise intensity values in the detected target space is less than the noise threshold, it means that the superimposed noise value corresponding to the compressor 120 operating at this operating frequency will not exceed the noise threshold. Obtaining a plurality of noise intensity values within the second preset time period makes the obtained superimposed noise value more representative.

[0063] In some embodiments, as Figure 5 shown, before step S120, controlling the compressor 120 to operate at a plurality of operating frequencies respectively, the following steps are further included:

[0064] S111. Control the indoor unit to enter the high wind mode; wherein, the high wind mode includes: controlling the fan of the indoor unit to operate; controlling the air deflector at the air outlet of the indoor unit to open a preset opening degree to block the air flow blown out from the air outlet.

[0065] That is to say, before executing the control of the compressor 120 to operate at a plurality of operating frequencies respectively, first open the air deflector to a preset opening degree, so that the indoor unit has a smaller air output volume, thereby making the operating load of the outdoor unit 100 smaller, and avoiding the problem that the compressor 120 of the outdoor unit 100 runs unstably when the outdoor unit 100 operates under a large load condition. On the one hand, it can greatly reduce the time for obtaining a plurality of superimposed noise values and improve the detection efficiency; on the other hand, it makes the detected superimposed noise value more representative.

[0066] In some embodiments, before the step S120 of controlling the compressor 120 to operate at multiple operating frequencies respectively, the following steps are further included:

[0067] S112. Adjust the frequency limit of the compressor 120 to the rated maximum frequency limit. Thus, the frequency range in which the compressor 120 can operate is larger, so that the noise conditions corresponding to the compressor 120 at its respective operating frequencies can be detected more comprehensively, thereby ensuring that the compressor 120 of the outdoor unit 100 does not generate excessive noise during operation.

[0068] In some embodiments, before the step S120 of controlling the compressor 120 to operate at multiple operating frequencies respectively, the following steps are further included:

[0069] S101. Obtain a startup instruction.

[0070] S102. In response to the startup instruction, determine whether the air conditioner unit is starting up for the first time.

[0071] S120. If so, execute the step of controlling the compressor 120 to operate at multiple operating frequencies respectively.

[0072] That is to say, the control method of the air conditioner unit in the embodiments of the present invention is executed through the initialization program of the first startup of the air conditioner unit, rather than being controlled and executed by the user through the control panel of the air conditioner unit.

[0073] When the air conditioner unit is starting up for the first time, the control method of the air conditioner unit in the embodiments of the present invention is executed. Thus, the target operating frequencies of the compressor 120 that need to be skipped can be detected before the normal operation of the air conditioner unit, so that the subsequent operation of the air conditioner unit will not have a situation of excessive noise.

[0074] Next, the specific implementation process of the control method of the air conditioner unit in the embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0075] S101. Obtain a startup instruction.

[0076] S102. In response to the startup instruction, determine whether the air conditioner unit is starting up for the first time.

[0077] S120. If so, execute step 120.

[0078] Step 120 includes controlling the compressor 120 to operate at multiple operating frequencies respectively, and detecting the superimposed noise value corresponding to each operating frequency.

[0079] Among them, before executing step 120, step S111 and step S112 are executed first. Step S111 includes controlling the indoor unit to enter the high wind mode. Step S112 includes adjusting the frequency limit of the compressor 120 to the rated maximum frequency limit.

[0080] S200. Determine at least one superimposed noise value greater than or equal to the noise threshold from multiple superimposed noise values, denoted as the target noise value; determine at least one operating frequency corresponding to the target noise value, denoted as the target operating frequency.

[0081] S300. Generate a frequency hopping parameter according to the target operating frequency, where the frequency hopping parameter describes the operating frequencies to be skipped during the operation of the compressor 120.
