[0035] In order to make the purposes, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be described clearly and completely below in conjunction with the drawings in the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort belong to the scope of protection of the present 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 interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally a category and do not limit the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / ", generally indicates that the objects before and after are in a "or" relationship.

[0037] The operation principle of the air conditioner related to the embodiments of the present application is described in detail as follows:

[0038] As shown in Figure 1 , the compressor compresses the refrigerant (cooling medium) and delivers it to the condenser through the pipeline. The high-temperature and high-pressure gaseous refrigerant releases heat in the condenser and becomes a medium-temperature and high-pressure liquid refrigerant. Then, the medium-temperature and high-pressure liquid refrigerant is depressurized by the capillary tube (throttling unit) and becomes a low-temperature and low-pressure liquid refrigerant. The low-temperature and low-pressure liquid refrigerant is delivered to the evaporator and evaporated into a 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 delivered to the compressor and participates 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; on the contrary, 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 arranged in the outdoor unit, when the air conditioner is running in the cooling or heating mode, the outdoor unit will inevitably produce a large noise, especially in summer, many families will open the window for ventilation, and the influence is more.

[0040] In view of the above-mentioned technical problems in related technologies, the embodiments of this application conceive of dividing a day into multiple time periods based on the different tolerance levels of human beings (including users and other neighbors) to noise at different times, and setting different maximum allowable noise values ​​for each time period, thereby adjusting the operating parameters of the air conditioner. This can not only reduce the impact on neighbors, but also ensure the user experience to a certain extent.

[0041] The following description, in conjunction with the accompanying drawings, details the control method for reducing noise from an outdoor air conditioning unit provided in this application through specific embodiments and application scenarios.

[0042] like Figure 2 As shown in the embodiment of this application, a control method for reducing the noise of an outdoor air conditioning unit is provided. The method may include the following steps 201 and 202:

[0043] Step 201: Obtain 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 permissible noise value corresponding to the target time period.

[0045] For example, since the control method for reducing the noise of the outdoor unit of an air conditioner provided in this application embodiment is based on the different tolerance levels of the human body to noise at different times, the day is divided into multiple different time periods, and different maximum noise allowable values ​​are set for each time period, when determining 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] For example, after determining the time period to which the current moment belongs, the maximum allowable noise value corresponding to the current time period, i.e. the target noise value mentioned above, can be determined by querying a database or other means.

[0047] It's understandable that cooking at lunchtime, children playing, and watching TV generate significant household noise. During these times, users are not very sensitive to the noise from the air conditioner, meaning the noise has a relatively small impact on other neighbors. Therefore, the maximum allowable noise level for these time periods can be set higher. Conversely, after lunch or at night, when people are resting and sleeping, users are less sensitive to the noise from the air conditioner, meaning the noise has a greater impact on other neighbors. Therefore, the maximum allowable noise level for these time periods can be set lower.

[0048] In step 202, a target operation parameter is determined according to the target noise value, and the operation of the air conditioner is controlled according to the target operation 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 operation parameter includes at least one of the following: the operation frequency of the compressor, and the fan rotating speed of the outdoor unit.

[0050] For example, after obtaining the target noise value, the operation parameter 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, different time periods can be divided according to different noise tolerance of human body in different time periods, and different maximum noise allowed values can be set for each time period.

[0052] For example, before step 201, the control method for reducing the noise of the outdoor unit of the air conditioner provided by the embodiment of the present application can further include the following step 203.

[0053] In step 203, different time periods are divided according to the noise tolerance of human body in different time periods, a plurality of time periods are obtained, and the maximum noise allowed value corresponding to each time period in the plurality of time periods is determined.

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

[0055] It should be noted that the division result of the time period can be obtained by questionnaire survey, or can also be obtained according to the collected historical complaint data. At the same time, the division result of the time period can also be manually set by the user according to the actual situation of the neighbors, for example, a neighbor works in the morning, and other neighbors go out to work and need to rest at home at this time. At this time, the user can adjust the division result of the time period according to the actual situation of the neighbor, and set the corresponding maximum noise allowed value, so as to avoid great influence on the neighbor.

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

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

[0058] In step 204, a vibration signal collected by a vibration signal sensor arranged on the outdoor unit is obtained.

[0059] wherein the vibration signal comprises a vibration amplitude and a vibration frequency;

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

[0061] Exemplarily, the noise value of the outdoor unit can be determined according to the vibration signal collected by the vibration signal sensor arranged on the outdoor unit. Specifically, the corresponding relationship between the vibration signal and the noise value of the outdoor unit can be obtained through experiments, that is, after the target relationship table of the vibration signal and the noise value is obtained through experiments, the noise value matched with the collected vibration signal can be queried based on the target relationship table.

[0062] Exemplarily, after the noise value of the outdoor unit is obtained, it can be judged whether the noise value generated by the outdoor unit at the current time will have a greater impact on the neighbors.

[0063] Further, in a possible implementation, since each component of the outdoor unit will generate greater noise as the use time increases, the use 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 can further include the following steps 205a1 and 205a2:

[0065] Step 205a1, obtaining a total running time of the air conditioner, and determining a noise adjustment coefficient according to the running 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] Wherein, in the case that the total running time is less than or equal to a preset threshold, the noise adjustment coefficient is 1; in the case that the total running time is greater than the preset threshold, the noise adjustment coefficient is greater than 1 and positively correlated with the total running time.

[0068] It can be understood that when the use time of the air conditioner is within a certain period of time, although each component of the outdoor unit will also age, it will not have any impact on the operation of the air conditioner and will not additionally increase the noise generated by the outdoor unit; when the use time of the air conditioner exceeds a certain period of time, greater noise will be generated as the use time increases.

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

[0070] Step 202a, in the case that the current noise value is greater than the target noise value, it is determined that the adjustment condition is met, and a target operation parameter is determined according to the target noise value, and the operation of the air conditioner is controlled according to the target operation parameter.

[0071] For example, after the current noise value of the outdoor unit is determined, it can be determined whether the operation parameter of the air conditioner needs 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 can include the following step 202a1 and step 202a2:

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

[0074] Step 202a2, adjusting the current operation parameter according to the operation parameter adjustment value to obtain the target operation parameter.

[0075] The current environment parameter includes an outdoor environment temperature and an indoor environment temperature, and the current operation parameter includes at least one of a set temperature of the air conditioner and an operation mode of the air conditioner, and the operation parameter adjustment value is used to adjust each of the current operation parameters.

[0076] For example, the larger the target difference value is, the larger the adjustment amount of the operation parameter of the air conditioner is; when the air conditioner is used in summer (high outdoor environment temperature), the higher the outdoor environment temperature is, the larger the adjustment amount of the operation parameter of the air conditioner is; similarly, when the air conditioner is used in summer, the higher the indoor environment temperature is, the larger the adjustment amount of the operation parameter of the air conditioner is. Since the doors and windows are mostly closed in winter (low outdoor environment temperature), the noise generated by the outdoor unit has less impact on the neighbors, and no additional control is needed.

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

[0078] Step 202a11, in the case that the outdoor environment temperature is greater than a first preset temperature or the indoor environment temperature is greater than a second preset temperature, determining the first parameter adjustment value according to the target difference value and the current operation parameter.

[0079] Step 202a12, determining the first parameter adjustment value as the operation 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] For example, when the outdoor ambient temperature is greater than the first preset temperature, or the indoor ambient temperature is greater than the second preset temperature, it means that the air conditioner must reduce the indoor ambient temperature by cooling. At this time, the noise generated by the outdoor unit can be reduced by reducing the compressor operating frequency and / or reducing the outdoor unit fan speed.

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

[0083] Step 202a13: If the target difference is greater than the preset difference 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, then 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 operating mode of the air conditioner to the 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 blowing air.

[0087] If the target difference is greater than 0 and less than the preset difference, it means that the noise level generated by the outdoor unit is relatively low. The noise can be reduced by lowering the compressor operating frequency and / or lowering the outdoor unit fan speed. If the target difference is greater than the preset difference, it means that the noise level generated by the outdoor unit is relatively high. Lowering the compressor operating frequency and / or lowering the outdoor unit fan speed will not be effective enough in reducing the noise. The air conditioner's operating mode needs to be adjusted to the fan-only mode to significantly reduce the noise level generated by the outdoor unit.

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

[0089] For example, such as Figure 3As shown in the complete flowchart of the control method for reducing noise of an outdoor unit of an air conditioner provided by the embodiment of the present application, first, a vibration signal of the outdoor unit is collected, and a noise value P1 of the outdoor unit is calculated according to the collected vibration signal; then, a maximum noise allowed value P0 corresponding to a current time period is obtained, and a size relationship between P1 and P0 is determined. When P1>P0, a difference value P2 of P1-P0 is calculated, and a running parameter Q of the air conditioner is determined according to the P2. Finally, the running of the air conditioner is controlled according to the running parameter Q, so as to reduce the noise generated by the outdoor unit.

[0090] The control method for reducing noise of an outdoor unit of an air conditioner provided by the embodiment of the present application first obtains a current time, and determines a target time period to which the current time belongs and a target noise value corresponding to the target time period; then, a target running parameter is determined according to the target noise value, and the running of the air conditioner is controlled according to the target running 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; wherein the target noise value is a maximum noise allowed value corresponding to the target time period; the target running parameter includes at least one of the following: a running frequency of a compressor, a fan rotating speed of the outdoor unit. In this way, the influence 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 noise of an outdoor unit of an air conditioner provided by the embodiment of the present application can be executed by a control device for reducing noise of an outdoor unit of an air conditioner, or a control module in the control device for reducing noise of an outdoor unit of an air conditioner for executing the control method for reducing noise of an outdoor unit of an air conditioner.
