[0035] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0036] 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.

[0037] The operating principle of the air conditioner involved in the embodiment of the present application is described in detail below:

[0038] like Figure 1 As shown in the figure, the compressor compresses the refrigerant (coolant) and transports it to the condenser through a pipeline. The high-temperature and high-pressure gaseous refrigerant releases heat in the condenser and becomes a medium-temperature and high-pressure liquid refrigerant. After that, the medium-temperature and high-pressure liquid refrigerant is depressurized by a capillary tube (throttling unit) and becomes a low-temperature and low-pressure liquid refrigerant. The low-temperature and low-pressure liquid refrigerant is transported to the evaporator to evaporate from liquid to gas, and absorbs a large amount of heat during the evaporation process. Finally, the low-temperature and low-pressure gaseous refrigerant in the evaporator is transported to the compressor to participate in the next cycle. When the air conditioner is cooling, the heat exchanger of the outdoor unit is the condenser, and the heat exchanger of the indoor unit is the evaporator; conversely, when the air conditioner is heating, the heat exchanger of the outdoor unit is the evaporator, and the heat exchanger of the indoor unit is the condenser.

[0039] According to the above content, since the compressor is installed in the outdoor unit, when the air conditioner is running in cooling or heating mode, the outdoor unit will inevitably produce a lot of noise, especially in summer when many families will open windows for ventilation, and the impact will be greater.

[0040] In response to the above-mentioned technical problems existing in the related art, the embodiments of the present application conceive of dividing a day into multiple time periods according to the different tolerance levels of the human body (including users and other neighbors) to noise in different time periods, and setting different maximum allowable noise values ​​for each time period, so as to adjust the operating parameters of the air conditioner, which can not only reduce the impact on neighbors, but also ensure the user experience to a certain extent.

[0041] The control method for reducing the noise of an air conditioner outdoor unit provided in the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0042] like Figure 2 As shown, an embodiment of the present application provides a control method for reducing the noise of an air conditioner outdoor unit, and the method may include the following steps 201 and 202:

[0043] Step 201: Acquire the current time, and determine the target time period to which the current time belongs and the target noise value corresponding to the target time period.

[0044] The target noise value is the maximum allowable noise value corresponding to the target time period.

[0045] For example, since the control method for reducing the noise of the air conditioner outdoor unit provided in the embodiment of the present application is based on the different tolerance of the human body to noise in different time periods, a day is divided into multiple different time periods, and a different maximum allowable noise value is set for each time period. Therefore, when judging whether the noise value at the current moment will affect the neighbors, it is necessary to first obtain the current time and determine the current time period based on the current time.

[0046] Exemplarily, after determining the time period to which the current moment belongs, the maximum allowable noise value corresponding to the current time period, ie, the above-mentioned target noise value, can be determined by querying a database or the like.

[0047] It is understandable that cooking at noon, children playing and fighting, watching TV, etc. will generate a lot of living noise. At this time, the user is not sensitive to the noise generated by the air conditioner, that is, the noise generated by the air conditioner at this time has little impact on other neighbors. Therefore, the maximum allowable noise value corresponding to this time period can be set to be slightly larger; after lunch or at night is the time for rest and sleep. At this time, the user is not more sensitive to the noise generated by the air conditioner, that is, the noise generated by the air conditioner at this time has a greater impact on other neighbors. Therefore, the maximum allowable noise value corresponding to this time period can be set to be slightly smaller.

[0048] Step 202: determine a target operating parameter according to the target noise value, and control the operation of the air conditioner according to the target operating parameter, so that the noise value generated by the outdoor unit of the air conditioner is less than or equal to the target noise value.

[0049] The target operating parameter includes at least one of the following: an operating frequency of the compressor and a fan speed of the outdoor unit.

[0050] For example, after obtaining the target noise value, the operating parameters of the air conditioner can be adjusted based on the target noise value so that the noise value generated by the outdoor unit of the air conditioner is reduced to below the target noise value.

[0051] Optionally, in the embodiment of the present application, a day can be divided into multiple different time periods according to the different tolerance levels of the human body to noise in different time periods, and a different maximum noise allowable value can be set for each time period.

[0052] Exemplarily, before the above step 201, the control method for reducing the noise of the air conditioner outdoor unit provided in the embodiment of the present application may further include the following step 203:

[0053] Step 203: Divide the time periods into different time periods according to the human body's tolerance to noise, obtain multiple time periods, and determine the maximum noise allowable value corresponding to each of the multiple time periods.

[0054] The target time period is one of the multiple time periods.

[0055] It should be noted that the above time period division results can be obtained by questionnaire survey or by collected historical complaint data. At the same time, the user can also manually set it according to the actual situation of the neighbors. For example, a neighbor works in the middle shift and needs to rest at home when other neighbors go out to work. At this time, the user can adjust the above time period division results according to the actual situation of the neighbor and set the corresponding maximum noise allowable value to avoid a greater impact on the neighbor.

[0056] Optionally, in an embodiment of the present application, in order to avoid interference of the alarm sound of outdoor vehicles or other loud sounds in the judgment of the outdoor unit noise, the noise value of the outdoor unit can be judged by collecting the vibration signal of the outdoor unit.

[0057] For example, before the above step 202, the control method for reducing the noise of the outdoor unit of the air conditioner provided in the embodiment of the present application may further include the following steps 204 and 205:

[0058] Step 204: Acquire a vibration signal collected by a vibration signal sensor provided on the outdoor unit.

[0059] Wherein, the vibration signal includes: vibration amplitude and vibration frequency;

[0060] Step 205: determine the current noise value of the outdoor unit according to the vibration signal, and determine whether an adjustment condition is met according to the current noise value and the target noise value.

[0061] For example, the noise value of the outdoor unit can be determined based on the vibration signal collected by the vibration signal sensor provided on the outdoor unit. Specifically, the corresponding relationship between the vibration signal and the noise value of the outdoor unit can be obtained by experiment, that is, after obtaining the target relationship comparison table of the vibration signal and the noise value by experiment, the noise value matching the collected vibration signal can be queried based on the target relationship comparison table.

[0062] For example, after obtaining the noise value of the outdoor unit, it can be determined whether the noise value generated by the outdoor unit at the current time will have a greater impact on neighbors.

[0063] Furthermore, in a possible implementation, since various components of the outdoor unit will generate greater noise as the usage time increases, the usage time of the air conditioner also needs to be considered in the process of determining the noise value of the outdoor unit.

[0064] Specifically, the above step 205 may further include the following steps 205a1 and 205a2:

[0065] Step 205a1: Obtain the total operating time of the air conditioner, and determine the noise adjustment coefficient according to the operating time.

[0066] Step 205a2: determining a noise value to be adjusted according to the vibration signal, and adjusting the noise value to be adjusted using the noise adjustment coefficient to obtain the current noise value;

[0067] When the total operating time is less than or equal to a preset threshold, the noise adjustment coefficient is 1; when the total operating time is greater than the preset threshold, the noise adjustment coefficient is greater than 1 and is positively correlated with the total operating time.

[0068] It is understandable that when the air conditioner is used for a certain number of years, although the various components of the outdoor unit will age, it will not have any impact on the operation of the air conditioner, nor will it increase the noise generated by the outdoor unit. When the air conditioner is used for more than a certain number of years, it will generate greater noise as the usage time increases.

[0069] Specifically, based on the current noise value determined in the above step, the above step 202 may include the following steps 202a:

[0070] Step 202a: when the current noise value is greater than the target noise value, determine that the adjustment condition is met, determine target operating parameters according to the target noise value, and control the operation of the air conditioner according to the target operating parameters.

[0071] For example, after determining the current noise value of the outdoor unit, it can be determined whether the operating parameters of the air conditioner need to be adjusted based on the current noise value and the target noise value corresponding to the target time period to which the current time belongs.

[0072] Specifically, the above step 202a may include the following steps 202a1 and 202a2:

[0073] Step 202a1, determining an operating parameter adjustment value according to a target difference between the current noise value and the target noise value, current operating parameters of the air conditioner, and current environmental parameters.

[0074] Step 202a2: Adjust the current operating parameter according to the operating parameter adjustment value to obtain the target operating parameter.

[0075] Among them, the current environmental parameters include: outdoor ambient temperature, indoor ambient temperature; the current operating parameters include at least one of the following: the set temperature of the air conditioner, the operating mode of the air conditioner; the operating parameter adjustment value is used to adjust each operating parameter in the current operating parameters.

[0076] For example, the larger the target difference is, the larger the adjustment of the air conditioner's operating parameters is; when the air conditioner is used in summer (when the outdoor ambient temperature is high), the higher the outdoor ambient temperature is, the larger the adjustment of the air conditioner's operating parameters is; similarly, when the air conditioner is used in summer, the higher the indoor ambient temperature is, the larger the adjustment of the air conditioner's operating parameters is. Since most doors and windows are closed in winter (when the outdoor ambient temperature is low), the noise generated by the outdoor unit during operation has little impact on neighbors and no additional control is required.

[0077] Specifically, the above step 202a1 may include the following steps 202a11 and 202a12:

[0078] Step 202a11: when the outdoor ambient temperature is greater than the first preset temperature, or the indoor ambient temperature is greater than the second preset temperature, determine the first parameter adjustment value according to the target difference and the current operating parameter.

[0079] Step 202a12: determine the first parameter adjustment value as the operating parameter adjustment value.

[0080] The first parameter adjustment value is used to reduce the operating frequency of the compressor and the fan speed of the outdoor unit.

[0081] Exemplarily, when the outdoor ambient temperature is greater than a first preset temperature, or the indoor ambient temperature is greater than a second preset temperature, it means that the air conditioner must lower the indoor ambient temperature by cooling. At this time, the noise generated by the outdoor unit can be reduced by reducing the operating frequency of the compressor and / or reducing the speed of the outdoor unit fan.

[0082] Specifically, the above step 202a1 may include the following steps 202a13 and 202a14:

[0083] Step 202a13: when the outdoor ambient temperature is less than or equal to the first preset temperature and the indoor ambient temperature is less than or equal to the second preset temperature, if the target difference is greater than the preset difference, determine the second operating parameter.

[0084] Step 202a12: determine the second parameter adjustment value as the operating parameter adjustment value.

[0085] The second parameter adjustment value is used to adjust the operation mode of the air conditioner to an air supply mode.

[0086] For example, when the outdoor ambient temperature is less than or equal to the first preset temperature, or the indoor ambient temperature is less than or equal to the second preset temperature, it means that the air conditioner can reduce the indoor ambient temperature by cooling or by supplying air.

[0087] At this time, if the target difference is greater than 0 and less than the preset difference, it means that the noise value generated by the outdoor unit is small, and the noise generated by the outdoor unit can be reduced by reducing the operating frequency of the compressor and / or reducing the speed of the outdoor fan; if the target difference is greater than the preset difference, it means that the noise value generated by the outdoor unit is large, and the effect of reducing the noise generated by the outdoor unit by reducing the operating frequency of the compressor and / or reducing the speed of the outdoor fan is not obvious enough, and the working mode of the air conditioner needs to be adjusted to the air supply mode to significantly reduce the noise value generated by the outdoor unit.

[0088] It should be noted that after the air conditioner is controlled to run for a preset time according to the target operating parameters, if the noise value of the outdoor unit is still greater than the maximum allowable noise value corresponding to the time period to which the current time belongs, it is necessary to further reduce the operating parameters of the compressor and the fan speed of the outdoor unit, that is, to reduce the operating parameters of the compressor and the fan speed of the outdoor unit at the same time.

[0089] For example, Figure 3As shown, it is a complete flow chart of the control method for reducing the noise of the outdoor unit of the air conditioner provided by the embodiment of the present application. First, the vibration signal of the outdoor unit is collected, and the noise value P1 of the outdoor unit is calculated according to the collected vibration signal; then, the maximum noise allowable value P0 corresponding to the current time period is obtained, and the magnitude relationship between P1 and P0 is determined. When P1>P0, the difference P2 of P1-P0 is calculated, and the operating parameter Q of the air conditioner is determined according to P2. Finally, the operation of the air conditioner is controlled according to the operating parameter Q to reduce the noise generated by the outdoor unit.

[0090] The control method for reducing the noise of the outdoor unit of the air conditioner provided in the embodiment of the present application first obtains the current time, and determines the target time period to which the current time belongs and the target noise value corresponding to the target time period; then, determines the target operating parameters according to the target noise value, and controls the operation of the air conditioner according to the target operating parameters, so that the noise value generated by the outdoor unit of the air conditioner is less than or equal to the target noise value; wherein the target noise value is the maximum noise allowable value corresponding to the target time period; the target operating parameters include at least one of the following: the operating frequency of the compressor, the fan speed of the outdoor unit. In this way, the impact of the outdoor unit noise on the surrounding neighbors when the air conditioner is running can be significantly reduced.

[0091] It should be noted that the control method for reducing the noise of the air conditioner outdoor unit provided in the embodiment of the present application can be executed by a control device for reducing the noise of the air conditioner outdoor unit, or a control module in the control device for reducing the noise of the air conditioner outdoor unit for executing the control method for reducing the noise of the air conditioner outdoor unit.
