Description

[0002] With the development of society, people's living standards are constantly improving, and air-conditioning systems have become commonly used electrical equipment in people's daily lives. Air-conditioning systems meet people's needs for the surrounding environment by adjusting and controlling parameters such as the temperature, humidity, and flow rate of the ambient air in buildings or structures.

[0003] When the air conditioning system is running, the compressor will cause the refrigerant to circulate in the pipeline, and the fan will guide the refrigerant in the pipeline to exchange heat with the air to adjust the air temperature, humidity, flow rate and other parameters. The higher the frequency of the compressor and the faster the speed of the fan, the faster the indoor environment requirements can be met.

[0004] However, the air conditioning system generates noise when it is running, such as the vibration noise when the compressor is running, or the noise generated when the fan rotates to blow air, which causes noise interference to users.

Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0043] See also Figure 1 , Figure 1 A schematic structural diagram of an air conditioning system provided in a feasible embodiment.

[0044] like Figure 1 As shown, the air conditioning system may include: an outdoor unit 10, a controller ( Figure 1 The outdoor unit 10 and the indoor unit 20 may be connected by a pipeline or the like.

[0045] The outdoor unit 10 includes: a compressor 11, a four-way reversing valve 12, an outdoor unit heat exchanger 13, an outdoor fan 14, an outdoor unit electronic expansion valve 15, a liquid side stop valve 16, a gas side stop valve 17, and a gas-liquid separator 18. The indoor unit 20 includes: an indoor unit electronic expansion valve 21, an indoor unit heat exchanger 22, and an indoor fan 23.

[0046] It is worth noting that Figure 1 The case where the air-conditioning system includes one indoor unit is merely shown for example. In actual application, the embodiment of the present application does not specifically limit the number of indoor units included in the air-conditioning system.

[0047] In some embodiments, the compressor 11 is disposed between the four-way reversing valve 12 and the gas-liquid separator 18 to compress the refrigerant and input the compressed refrigerant into the circulation system through the four-way reversing valve 12 to provide power for the circulation of the refrigerant.

[0048] In some embodiments, the four ports (C, D, S, E) of the four-way reversing valve 12 are respectively connected to the exhaust port of the compressor 11 (not shown in the figure), the outdoor unit heat exchanger 13, the gas-liquid separator 18 and the indoor unit heat exchanger 22 of each indoor unit.

[0049] The four-way reversing valve 12 is used to achieve the mutual conversion between the cooling mode and the heating mode of the air-conditioning system by changing the flow direction of the refrigerant in the system pipeline.

[0050] In some embodiments, one end of the outdoor heat exchanger 13 is connected to the compressor 11 through the four-way reversing valve 12, and the other end is connected to the indoor heat exchanger 22. The outdoor heat exchanger 13 is used to exchange heat between the refrigerant flowing in the heat transfer pipe of the outdoor heat exchanger 13 and the outdoor air to achieve the purpose of regulating the temperature.

[0051] In some embodiments, the outdoor fan 14 is connected to an outdoor fan (not shown in the figure) and is used to drive or change the speed of the outdoor fan to promote heat exchange between the refrigerant flowing in the heat transfer pipe of the outdoor unit heat exchanger 13 and the outdoor air, thereby achieving the purpose of auxiliary temperature regulation.

[0052] In some embodiments, the outdoor unit electronic expansion valve 15 and the indoor unit electronic expansion valve 21 are arranged between the indoor unit heat exchanger 22 and the outdoor unit heat exchanger 13. The outdoor unit electronic expansion valve 15 has the function of expanding and reducing the pressure of the refrigerant flowing through the outdoor unit electronic expansion valve 15, and can be used to adjust the flow rate of the refrigerant in the pipeline. In the same principle, the indoor unit electronic expansion valve 21 has the function of expanding and reducing the pressure of the refrigerant flowing through the outdoor unit electronic expansion valve 21, and can be used to adjust the flow rate of the refrigerant in the pipeline.

[0053] In some embodiments, the liquid-side stop valve 16 is disposed between the outdoor unit electronic expansion valve 15 and the indoor unit electronic expansion valve 21 .

[0054] In some embodiments, the gas-side stop valve 17 is disposed between the compressor 11 and the indoor unit heat exchanger 22 .

[0055] In some embodiments, the gas-liquid separator 18 is connected to the compressor 11 for separating the gaseous refrigerant and the liquid refrigerant.

[0056] In some embodiments, the indoor unit heat exchanger 22 is used to perform heat exchange between the refrigerant flowing in the heat transfer pipe of the indoor unit heat exchanger 22 and the indoor air.

[0057] In some embodiments, the indoor blower 23 is connected to an indoor fan (not shown) and is used to drive or change the speed of the indoor fan to promote heat exchange between the refrigerant flowing in the heat transfer pipe of the indoor unit heat exchanger 22 and the indoor air.

[0058] The controller is the control center of the air conditioning system 100 , and can be used to control the operation of various components in the air conditioning system 100 , so that the various components of the air conditioning system 100 operate to realize various functions of the air conditioning system 100 .

[0059] In some embodiments, the controller refers to a device that can generate an operation control signal according to an instruction operation code and a timing signal to instruct the outdoor unit 10 and the indoor unit 20 to execute the control instruction. Exemplarily, the controller can be a central processing unit (CPU), a general-purpose processor network processor (NP), a digital signal processor (DSP), a microprocessor, a microcontroller, a programmable logic device (PLD), or any combination thereof. The controller can also be other devices with processing functions, such as circuits, devices, or software modules, and the embodiments of the present application do not impose any restrictions on this.

[0060] Those skilled in the art will understand that Figure 1 The hardware structure shown in the figure does not constitute a limitation on the air-conditioning system. The air-conditioning system may include more or fewer components than shown in the figure, or a combination of certain components, or a different arrangement of components. This application does not make specific limitations on this.

[0061] When the air conditioning system is in operation, the compressor will cause the refrigerant to circulate in the pipeline, and the fan (outdoor fan 14 and indoor fan 22) will guide the refrigerant in the pipeline to exchange heat with the air to achieve the adjustment of air temperature, humidity, flow rate and other parameters. The higher the frequency of the compressor and the faster the speed of the fan, the faster the indoor environmental requirements can be met.

[0062] However, the air conditioning system generates noise when it is running, such as the vibration noise when the compressor is running, or the noise generated when the fan rotates to blow air, which causes noise interference to users. It is difficult for existing air conditioning systems to achieve a balance between normal operation and noise reduction when they are running, resulting in a poor user experience. If the air conditioner is turned off, users cannot enjoy the comfort brought by the air conditioner, resulting in a poor user experience.

[0063] Based on this, the air-conditioning system provided in the embodiment of the present application also includes a first noise sensor for detecting the ambient noise value of the environment in which the air-conditioning system is located, and a second noise sensor for detecting the air-conditioning noise value emitted by the operation of the air-conditioning system.

[0064] It should be understood that in order to avoid the influence of the air conditioning noise value emitted by the air conditioning system on the environmental noise value, the first noise sensor can be set at a position away from the outdoor unit and indoor unit of the air conditioning system to avoid the measured environmental noise value being affected by the air conditioning noise value.

[0065] In some embodiments, see Figure 2 The noise sensor (the first noise sensor and the second noise sensor) is equipped with a sound-sensitive capacitive electret microphone 201, which can measure the intensity of the noise. When an object makes a sound, the sound wave vibrates and displaces the electret film in the microphone, causing the capacitor to change, thereby generating a small voltage corresponding to the change, and then the conversion module 202 can determine the intensity of the noise based on the voltage, realizing the conversion from optical signal to electrical signal.

[0066] In this way, the air conditioning system provided in the embodiment of the present application can adjust the operating state of the compressor and / or the fan according to the detected environmental noise value and the air conditioning noise value, as well as the environmental requirement value related to the location of the air conditioning system and the current time, so that the air conditioning noise value is below the environmental requirement value and the environmental noise value. That is, the noise emitted by the operation of the air conditioning system is lower than the environmental noise value and the environmental requirement value of the environment in which the air conditioning system is located, thereby helping to reduce the impact of the air conditioning noise value emitted by the operation of the air conditioning system on the user, thereby improving the user experience.

[0067] See also Figure 3 In the air conditioning system provided in the embodiment of the present application, the controller is configured to execute S301-S304:

[0068] S301: Obtain environmental noise value and air conditioning noise value.

[0069] The environmental noise value of the environment in which the air-conditioning system is located detected by the first noise sensor and the air-conditioning noise value emitted by the air-conditioning system during operation detected by the second noise sensor are obtained.

[0070] As a possible implementation, see Figure 4 , S301 can be specifically implemented as follows:

[0071] S401. In response to receiving an intelligent noise on instruction, obtaining an environmental noise value and an air conditioning noise value.

[0072] That is to say, in the air conditioning system provided in the embodiment of the present application, when operating normally, the user can select the wind speed of the indoor fan or the frequency of the compressor according to their own needs. When the user turns on the noise control mode, the air conditioning system starts to obtain the environmental noise value and the air conditioning noise value after receiving the user's instruction to reduce noise, and then executes the control of the air conditioning system to reduce noise.

[0073] In this way, users can independently control the operation of the air-conditioning system and improve the user experience.

[0074] It should be understood that the method of obtaining the environmental noise value and the air-conditioning noise value in the embodiment of the present application can be set according to needs, and the embodiment of the present application does not impose any limitation on this.

[0075] In some embodiments, since the air conditioning noise value does not change in real time with the adjustment of the compressor and / or the fan, it may take some time for the air conditioning noise value to stabilize after the status of the compressor and / or the fan is adjusted.

[0076] As a feasible implementation method, S401 may be specifically implemented as follows: in response to receiving the intelligent noise start instruction, obtaining the ambient noise value and the air-conditioning noise value at every preset period.

[0077] Among them, the preset period is pre-set by the system and can be set according to needs during actual application. The embodiment of the present application does not impose any restrictions on this.

[0078] Since the air conditioning system needs to adjust the operating status of the compressor and / or the fan according to the ambient noise value and the air conditioning noise value to adjust the air conditioning noise value, and the air conditioning noise value does not change in real time with the adjustment of the compressor and / or the fan, after receiving the user's instruction to reduce noise, the air conditioning system obtains the ambient noise value and the air conditioning noise value at a preset interval, which can avoid the problem of unstable operation of the air conditioning system and inaccurate air conditioning noise value.

[0079] S302: Obtain the location and current time of the air conditioning system.

[0080] S303: Determine an environmental requirement value corresponding to the air conditioning system according to the location of the air conditioning system and the current time.

[0081] It is understandable that users have different requirements for noise depending on where the air conditioning system is located. For example, users in areas such as sanatoriums, high-end villas, and high-end hotels will have higher requirements for noise, while users in areas such as shopping malls and schools will have lower requirements for noise. At the same time, users' requirements for noise vary with time. For example, at night when users need to rest, they are more sensitive to noise and thus have higher requirements for noise.

[0082] Based on this, the air-conditioning system provided in the embodiment of the present application needs to first determine the environmental requirement value according to its own location and the current time, and then control the operating state of the air-conditioning based on the environmental requirement value.

[0083] In some embodiments, the correspondence between the environmental requirement value and the place and time may be pre-stored in the memory of the air conditioning system, so that during operation, the environmental requirement value to be used may be determined based on the correspondence.

[0084] Exemplarily, as shown in Table 1, Table 1 is a classification table of environmental requirement values ​​provided in an embodiment of the present application.

[0085] Table 1

[0086] Serial number place Daylight(dB) Night(dB) 1 Rehabilitation facilities 50 40 2 Residential Places 55 45 3 Supermarkets 60 50 4 industry 64 55 5 Traffic artery. 70 55 … … …

[0087] In this way, the air conditioning system can determine the corresponding place according to its own location, and determine whether the current time corresponds to day or night according to the current time and the location. Then, the current noise requirement value can be determined according to the corresponding relationship in Table 1.

[0088] S304: When the air conditioner noise value is above the environmental noise value or the environmental requirement value, control the operating frequency of the compressor to be lowered by a preset frequency, and / or control the speed of the fan to be lowered by a preset speed.

[0089] It should be understood that in the embodiment of the present application, the preset frequency and the preset speed are both preset by the system, and can be set according to the needs in the actual application process, and the embodiment of the present application does not make any limitation on this. For example, as a feasible implementation method, the preset frequency is 100HZ and the preset speed is 50r / min.

[0090] Make the air conditioning noise value below the environmental requirement value and the environmental noise value.

[0091] In some embodiments, see Figure 5 , you can adjust the operating status of the air conditioning system according to the following steps:

[0092] S501, obtaining an environmental noise value and an air conditioning noise value, and determining an environmental requirement value.

[0093] The air conditioning system obtains the environmental noise value and air conditioning noise value in real time during operation, and calculates the corresponding environmental requirement value based on Table 1, its own location information and current time.

[0094] S502: Determine whether the environmental noise value is greater than the environmental requirement value.

[0095] If the obtained environmental noise value Le1 is greater than the environmental requirement value, execute S5031; if the obtained environmental noise value Le1 is less than or equal to the environmental requirement value, execute S5041.

[0096] S5031. Determine whether the air conditioner noise value is greater than the environmental requirement value.

[0097] If the air conditioning noise value is greater than the environmental requirement value, execute S5032; if the air conditioning noise value is less than or equal to the environmental requirement value, execute S505.

[0098] S5032. Adjust the operating status of the compressor and / or the fan so that the air conditioning noise value is less than the environmental requirement value.

[0099] The operating frequency of the compressor is controlled to be lowered to a preset frequency, and / or the speed of the fan is controlled to be lowered to a preset speed, so that the air conditioning noise value is less than the environmental requirement value.

[0100] S5041. Determine whether the air conditioner noise value is greater than the ambient noise value.

[0101] If the air conditioning noise value is greater than the ambient noise value, execute S5042; if the air conditioning noise value is less than or equal to the ambient noise value, execute S505.

[0102] S5042: Adjust the operating status of the compressor and / or the fan so that the air conditioning noise value is smaller than the ambient noise value.

[0103] The operating frequency of the compressor is controlled to be lowered to a preset frequency, and / or the speed of the fan is controlled to be lowered to a preset speed, so that the air conditioning noise value is lower than the environmental noise value.

[0104] S505. Maintain the current operating conditions.

[0105] It should be understood that the method for obtaining the environmental noise value and the air-conditioning noise value in the embodiment of the present application can be to obtain them at every preset period or to obtain them in real time, and the embodiment of the present application does not impose any limitation on this.

[0106] In some embodiments, the obtained environmental noise value and the air conditioner noise value after adjusting the operating state of the compressor and / or the fan can be recorded. Please refer to Table 2, which is a correspondence table of environmental noise values ​​and air conditioner noise values ​​provided in an embodiment of the present application.

[0107] Table 2

[0108] Serial number Environmental noise level (dB) Air conditioning noise level (dB) 1 Le1 Ld1 2 Le2 Ld2 3 Le3 Ld3 4 Le4 L4 5 Le5 Ld5 … … …

[0109] It is understandable that the environmental noise values ​​Le1, Le2, etc. will continue to change over time, and the air conditioning system will also continuously adjust its operating state to make the air conditioning noise value reach the corresponding Ld1, Ld2, etc.

[0110] It can be seen that the air conditioning system provided in the embodiment of the present application can adjust the operating state of the compressor and / or the fan according to the detected environmental noise value and the air conditioning noise value, as well as the environmental requirement value related to the location of the air conditioning system and the current time, so that the air conditioning noise value is below the environmental requirement value and the environmental noise value. That is, the noise emitted by the operation of the air conditioning system is lower than the environmental noise value and the environmental requirement value of the environment in which the air conditioning system is located, thereby helping to reduce the impact of the air conditioning noise value emitted by the operation of the air conditioning system on the user, thereby improving the user experience.

[0111] In some embodiments, since users usually need to rest at night and have higher requirements for noise when resting, users usually turn on the noise control mode when sleeping, and the air conditioning system controls the noise reduction after receiving the user's instruction to reduce noise.

[0112] As a possible implementation, see Figure 6 The air conditioning system provided in the embodiment of the present application may further perform the following steps:

[0113] S601. Acquire data related to the user's living habits.

[0114] It should be understood that the embodiments of the present application do not specifically limit the method of obtaining data related to the user's living habits. For example, as a feasible implementation method, the air conditioning system can determine the user's living habit data based on the user's operation of the air conditioning system.

[0115] As another feasible implementation method, the air-conditioning system can obtain data sent by sensors that detect human sleep time and sleep stages, and use it as the user's living habit data.

[0116] As another feasible implementation method, the air-conditioning system can be connected to the user's terminal device for data exchange, so that the user can set his or her own sleeping time, waking time, acceptable noise level, etc. on the terminal device, and then the air-conditioning system obtains data related to the user's living habits through the terminal device.

[0117] S602: Determine a sleep time period and a sleep noise value corresponding to the user according to data related to the user's living habits.

[0118] It is understandable that the sleeping noise value is the maximum noise that the user can accept when sleeping, that is, if the air-conditioning noise value exceeds the user's corresponding sleeping noise value, it will have a certain impact on the user.

[0119] For example, please refer to Table 3, which is a user living habit table provided in an embodiment of the present application.

[0120] Table 3

[0121]

[0122] It should be understood that the sleeping time and waking time shown in Table 3 are the corresponding sleeping time periods.

[0123] S603: During the sleep time period corresponding to the user, determine whether the air conditioning noise value is above the sleep noise value.

[0124] When the user is in the sleep time period corresponding to the user, it indicates that the user needs to sleep. If the air conditioning noise value is too high, it will affect the user's rest. Therefore, it is determined whether the air conditioning noise value is above the sleep noise value. If so, execute S704; if not, do nothing.

[0125] S704: Control the operating frequency of the compressor to reduce a preset frequency, and / or control the speed of the fan to reduce a preset speed.

[0126] The operating frequency of the compressor is controlled to be lowered to a preset frequency, and / or the speed of the fan is controlled to be lowered to a preset speed, so that the air conditioning noise value is less than the sleeping noise value corresponding to the user.

[0127] When the user is in the sleep time period corresponding to the user, it indicates that the user needs to sleep. If the air conditioner noise value is too high, it will affect the user's rest. Therefore, the compressor operating frequency is controlled to be lowered to a preset frequency, and / or the fan speed is controlled to be lowered to a preset speed, so that the air conditioner noise value is less than the user's corresponding sleep noise value, thereby preventing the air conditioner noise value from affecting the user's rest.

[0128] Since the fan speed and compressor frequency are the main factors affecting the air conditioning noise value, the air conditioning noise value can be reduced by reducing the fan speed and compressor frequency, so that the noise generated by the air conditioning system is less than the corresponding sleeping noise value of the user. The air conditioning noise value has been achieved without affecting the user, while taking into account the air conditioning effect.

[0129] In some embodiments, since the air conditioning noise value is related to the cooling / heating capacity of the air conditioning system, reducing the air conditioning noise value, that is, reducing the operating frequency of the compressor and / or reducing the speed of the fan, will cause the cooling / heating capacity of the air conditioning system to decrease. Therefore, when the air conditioning system adjusts the operating state so that the air conditioning noise value is lower than the sleeping noise value during the user's corresponding sleep time period, the immediate noise reduction will cause the air conditioning cooling / heating to attenuate, which will in turn affect the user's experience.

[0130] Based on this, as a feasible implementation method, the air-conditioning system provided in the embodiment of the present application also includes a temperature sensor for detecting the indoor temperature.

[0131] See also Figure 7 , the air conditioning system provided in the embodiment of the present application is also configured as follows:

[0132] S701: Determine the time difference between the current time and the sleep time corresponding to the user.

[0133] The sleeping time is the starting time of the sleeping time period corresponding to the user.

[0134] Determine the time difference between the current time and the sleep time corresponding to the user, that is, determine how long it will take to reach the sleep time of the user.

[0135] S702: When the time difference is less than or equal to the preset time, obtain the indoor temperature.

[0136] It should be understood that the preset time is pre-set by the system and can be set according to needs in actual application. The embodiment of the present application does not impose any restrictions on this. For example, as a feasible implementation method, the preset time is 30 minutes, and the indoor temperature is obtained when the time difference between the current time and the sleep time corresponding to the user is less than or equal to 30 minutes.

[0137] S703: If the temperature difference between the indoor temperature and the temperature set by the user is greater than or equal to a preset temperature difference threshold, control the operating frequency of the compressor to increase by a preset frequency, and / or control the speed of the fan to increase by a preset speed.

[0138] It should be understood that the preset temperature difference threshold is pre-set by the system and can be set according to needs in the actual application process, and the embodiment of the present application does not impose any restrictions on this. For example, as a feasible implementation method, the preset temperature difference threshold is 5 degrees Celsius. If the temperature difference between the indoor temperature and the user-set temperature is greater than or equal to 5 degrees Celsius, the operating frequency of the compressor is controlled to increase the preset frequency, and / or the speed of the fan is controlled to increase the preset speed.

[0139] When there is still a preset time left before the user's corresponding sleep time period, if the temperature difference between the indoor temperature and the temperature set by the user is greater than or equal to the preset temperature difference threshold, it indicates that the temperature of the space where the user is located (indoor temperature) cannot meet the user's needs, and the air-conditioning system needs to speed up cooling / heating so that the user's space can quickly reach the comfortable temperature required for sleeping.

[0140] In this way, when it is time to go to sleep, the temperature of the user's space is still at a comfortable temperature, and the user will not feel uncomfortable due to immediate noise reduction during sleep, which can improve the user experience.

[0141] In some embodiments, since the operating frequency of the compressor is controlled to increase by a preset frequency, and / or the speed of the fan is controlled to increase by a preset speed, the air conditioning noise value will increase, and the increased noise value will affect the user's experience, especially when the user is about to fall asleep (the time difference between the current time and the user's corresponding sleeping time is less than the preset time), the air conditioning noise value will affect the user's mood even more.

[0142] As a possible implementation, see Figure 8 In the air conditioning system provided in the embodiment of the present application, after S703, the controller is further configured to:

[0143] S801. According to the air conditioner noise value and the environmental requirement value, adjust the operating frequency of the compressor and / or the speed of the fan so that the difference between the air conditioner noise value and the environmental requirement value is less than or equal to a preset noise threshold.

[0144] It should be understood that the preset noise threshold is pre-set by the system and can be set according to needs during actual application. The embodiments of the present application do not impose any limitations on this.

[0145] As a feasible implementation method, if the air conditioner noise value is greater than the environmental requirement value, and the difference between the air conditioner noise value and the environmental requirement value is greater than the preset noise threshold, the operating frequency of the compressor is controlled to be reduced by a preset frequency, and / or the speed of the fan is controlled to be reduced by a preset speed, so as to reduce the air conditioner noise value, so that the difference between the air conditioner noise value and the environmental requirement value is less than or equal to the preset noise threshold.

[0146] As another feasible implementation method, if the air conditioner noise value is less than the environmental requirement value, and the difference between the air conditioner noise value and the environmental requirement value is greater than the preset noise threshold, the operating frequency of the compressor is controlled to increase by a preset frequency, and / or the speed of the fan is controlled to increase by a preset speed, so as to improve the cooling / heating capacity of the air conditioner system and quickly reach the comfortable temperature required for sleeping.

[0147] It should be understood that as a feasible implementation method, please refer to Fig. 9 After S604, the air conditioning system provided in the embodiment of the present application is further configured as follows:

[0148] S901. When it is time to get up, adjust the air conditioner operation state according to the ambient noise value and the air conditioner noise value.

[0149] When it is time for the user to get up, the user's requirement for noise will be slightly lower, and a slightly higher air-conditioning noise value will not affect the user. Therefore, the air-conditioning operating state is adjusted according to the environmental noise value and the air-conditioning noise value to restore the air-conditioning system to normal cooling / heating capacity.
