Description

TECHNICAL FIELD

Air conditioning systems adjust and control parameters such as temperature, humidity, and flow rate of air in the environment of a building or structure, meeting people's needs for the surrounding environment.

[0003] When the air conditioning system is running, the compressor promotes the circulation of refrigerant in the pipeline, and the fan guides the heat exchange between the refrigerant in the pipeline and the air to achieve the adjustment of parameters such as air temperature, humidity, and flow rate. 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 running, such as vibration noise when the compressor is running, or noise when the fan rotates to blow air, which disturbs the user.

Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0043] Please see Figure 1 , Figure 1 This is a schematic diagram of an air conditioning system provided as a feasible embodiment.

[0044] like Figure 1 As shown, the air conditioning system may include: outdoor unit 10, controller ( Figure 1 (Not shown in the image) and indoor unit 20. Outdoor unit 10 and indoor unit 20 can be connected via pipes, etc.

[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 shut-off valve 16, a gas-side shut-off 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 This is merely an illustrative example of an air conditioning system including one indoor unit. In actual applications, this application does not impose a specific limitation on the number of indoor units included in an air conditioning system.

[0047] In some embodiments, the compressor 11 is arranged between the four-way reversing valve 12 and the gas-liquid separator 18, for compressing the refrigerant and inputting 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 heat exchanger 13, the gas-liquid separator 18, and the indoor heat exchanger 22 of each indoor unit.

[0049] The four-way reversing valve 12 is used to realize 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 temperature adjustment.

[0051] In some embodiments, the outdoor fan 14 is connected to the outdoor fan (not shown in the figure), for driving or changing the rotating speed of the outdoor fan, to promote the heat exchange between the refrigerant flowing in the heat transfer pipe of the outdoor heat exchanger 13 and the outdoor air, to achieve the purpose of auxiliary temperature adjustment.

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

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

[0054] In some embodiments, the gas-side stop valve 17 is arranged between the compressor 11 and the indoor 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 heat exchanger 22 is used to exchange heat between the refrigerant flowing in the heat transfer pipe of the indoor heat exchanger 22 and the indoor air.

[0057] In some embodiments, the indoor fan 23 is connected with an indoor fan (not shown in the figure) for driving or changing the rotating speed of the indoor fan to promote heat exchange between the refrigerant flowing in the heat transfer pipe of the indoor 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 operation control signals according to instruction operation codes and timing signals to instruct the outdoor unit 10 and the indoor unit 20 to execute control instructions. For example, the controller can be a central processing unit (CPU), a general processor network processor (NP), a digital signal processing (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 make any limitation thereto.

[0060] Those skilled in the art can understand that, Figure 1 The hardware structure shown in the figure does not constitute a limitation on the air conditioning system, and the air conditioning system can include more or fewer components than the figure, or combine certain components, or different component arrangements, and the present application does not make any specific limitation thereto.

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

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

[0063] Based on this, the air conditioning system provided in the embodiments of the present application further comprises a first noise sensor for detecting an ambient noise value of an environment in which the air conditioning system is located, and a second noise sensor for detecting an air conditioning noise value emitted by 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 ambient noise value, the first noise sensor can be arranged at a position away from the outdoor unit and the indoor unit of the air conditioning system, so as to avoid the influence of the air conditioning noise value on the measured ambient noise value.

[0065] In some embodiments, referring to 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 noise. When an object produces 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 according to the voltage, realizing the conversion from an optical signal to an electrical signal.

[0066] In this way, the air conditioning system provided in the embodiments of the present application can adjust the running state of the compressor and / or the fan according to the detected ambient noise value and 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 ambient noise value. That is, the noise emitted by the air conditioning system is lower than the ambient noise value and the environmental requirement value of the environment in which the air conditioning system is located, thereby helping to reduce the influence of the air conditioning noise value emitted by the air conditioning system on the user, and thereby improving the user's experience.

[0067] Referring to Figure 3 , the air conditioning system provided in the embodiments of the present application, the controller is configured to perform S301-S304:

[0068] S301, obtaining an ambient noise value and an air conditioning noise value.

[0069] Obtaining the ambient 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 detected by the second noise sensor.

[0070] As a feasible implementation manner, referring to Figure 4 , S301 can be specifically implemented as:

[0071] S401, in response to receiving an intelligent noise start instruction, obtaining an ambient noise value and an air conditioning noise value.

[0072] That is, the air conditioning system provided by the embodiments of the present application can be used by the user to select the fan speed of the indoor fan or the frequency of the compressor according to the autonomous needs in normal operation. 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 only after receiving the instruction of the user needing to reduce noise, and then performs control of the air conditioning system to reduce noise.

[0073] In this way, the user can autonomously control the operation of the air conditioning system, and the user experience can be improved.

[0074] It should be understood that the manner of obtaining the environmental noise value and the air conditioning noise value in the embodiments of the present application can be set according to needs, and the embodiments of the present application do not make any limitation in this regard.

[0075] In some embodiments, since the air conditioning noise value is not changed in real time with the adjustment of the compressor and / or the fan, after the adjustment of the state of the compressor and / or the fan, it can take a period of time for the air conditioning noise value to stabilize.

[0076] As a feasible implementation manner, S401 can be specifically implemented as: in response to receiving the intelligent noise opening instruction, obtaining the environmental noise value and the air conditioning noise value every interval preset period.

[0077] The preset period is set by the system in advance, and in the actual application process, it can be set according to needs, and the embodiments of the present application do not make any limitation in this regard.

[0078] Since the air conditioning system needs to adjust the running state of the compressor and / or the fan according to the environmental noise value and the air conditioning noise value to adjust the air conditioning noise value, and the air conditioning noise value is not changed in real time with the adjustment of the compressor and / or the fan. Therefore, the air conditioning system obtains the environmental noise value and the air conditioning noise value every interval preset period after receiving the instruction of the user needing to reduce noise, which can avoid the problem that the obtained air conditioning noise value is inaccurate due to the unstable operation of the air conditioning system.

[0079] S302, obtaining the location where the air conditioning system is located and the current time.

[0080] S303, determining the environmental requirement value corresponding to the air conditioning system according to the location where the air conditioning system is located and the current time.

[0081] It can be understood that the user has different requirements for noise at different locations of the air conditioning system, such as in a sanatorium, a high-grade villa area, a high-grade hotel area, etc. The user's noise requirement standard will be higher, and in a shopping mall, a school, etc. The user's noise requirement standard will be lower. At the same time, since the user's noise requirement standard is different with time, such as at night when the user needs to rest, the user is more sensitive to noise, and the noise requirement standard will be higher.

[0082] Based on this, the air conditioning system provided by the embodiments of the present application needs to determine the environment requirement value according to the location and the current time, and then control the running state of the air conditioner based on the environment requirement value.

[0083] In some embodiments, the correspondence between the environment requirement value and the location and the time can be pre-stored in the memory of the air conditioning system, so that the environment requirement value needed to be used can be determined according to the correspondence during running.

[0084] For example, as shown in Table 1, Table 1 is a classification table of the environment requirement value provided by the embodiments of the present application.

[0085] Table 1

[0086] Figure 5 Ambient noise value (dB) Air conditioning noise value (dB) Le1 1 Ld1 50 40 2 Le2 55 45 3 Ld2 60 50 4 Le3 64 55 5 Ld3 70 55 … … …

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

[0088] S304, when the air conditioning noise value is higher than the environment noise value or the environment requirement value, the running frequency of the compressor is reduced by a preset frequency, and / or the rotating speed of the fan is reduced by a preset rotating speed.

[0089] It should be understood that in the embodiments of the present application, the preset frequency and the preset rotating speed are pre-set by the system, which can be set according to the needs in the actual application, and the embodiments of the present application do not make any limitation on this. For example, as a feasible implementation manner, the preset frequency is 100HZ, and the preset rotating speed is 50r / min.

[0090] So that the air conditioning noise value is lower than the environment requirement value and the environment noise value.

[0091] In some embodiments, referring to Le4 The running state of the air conditioning system can be adjusted according to the following steps:

[0092] S501, obtaining the environment noise value and the air conditioning noise value, and determining the environment requirement value.

[0093] The environment noise value and the air conditioning noise value are obtained in real time during the running of the air conditioning system, and the corresponding environment requirement value is calculated based on Table 1 according to the location information and the current time.

[0094] S502, judging whether the environment noise value is greater than the environment requirement value.

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

[0096] S5031, determining whether the air conditioner noise value is greater than the environment requirement value.

[0097] If the air conditioner noise value is greater than the environment requirement value, S5032 is executed; if the air conditioner noise value is less than or equal to the environment requirement value, S505 is executed.

[0098] S5032, adjusting the running state of the compressor and / or the fan, so that the air conditioner noise value is less than the environment requirement value.

[0099] Controlling the running frequency of the compressor to reduce a preset frequency, and / or controlling the rotating speed of the fan to reduce a preset rotating speed, so that the air conditioner noise value is less than the environment requirement value.

[0100] S5041, determining whether the air conditioner noise value is greater than the environment noise value.

[0101] If the air conditioner noise value is greater than the environment noise value, S5042 is executed; if the air conditioner noise value is less than or equal to the environment noise value, S505 is executed.

[0102] S5042, adjusting the running state of the compressor and / or the fan, so that the air conditioner noise value is less than the environment noise value.

[0103] Controlling the running frequency of the compressor to reduce a preset frequency, and / or controlling the rotating speed of the fan to reduce a preset rotating speed, so that the air conditioner noise value is less than the environment noise value.

[0104] S505, keeping the existing working condition running.

[0105] It should be understood that the manner of obtaining the environment noise value and the air conditioner noise value in the embodiments of the present application can be obtained every interval preset period or obtained in real time, and the embodiments of the present application do not make any limitation thereto.

[0106] In some embodiments, the obtained environment noise value and the air conditioner noise value after adjusting the running state of the compressor and / or the fan can be recorded. Please refer to Table 2, which is a corresponding table of environment noise value and air conditioner noise value provided by the embodiments of the present application.

[0107] Table 2

[0108] Ld4 Le5 Ld5 1 Figure 6 Figure 7 2 Figure 8 Figure 9 3 Figure 10 Figure 11 4 Figure 12 Figure 13 5 Figure 14 Figure 15 … … …

[0109] It can be understood that the environment noise values Le1, Le2…… will change constantly over time, and the air conditioner system will also constantly adjust the running state to make the air conditioner noise values reach the corresponding Ld1, Ld2……

[0110] It can be seen that the air conditioning system provided by the embodiment of the present application can adjust the running state of the compressor and / or the fan according to the detected environmental noise value and the air conditioning noise value, and the environmental requirement value related to the location and the current time of the air conditioning system, 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 air conditioning system is lower than the environmental noise value and the environmental requirement value of the environment where the air conditioning system is located, thereby helping to reduce the influence of the air conditioning noise value emitted by the air conditioning system on the user, and thereby improving the user's experience.

[0111] In some embodiments, since the user usually needs to rest at night, the user's requirement for noise will be higher when the user is resting. Therefore, the user usually turns on the noise control mode when sleeping, and the air conditioning system controls the air conditioning system to reduce noise after receiving the instruction of the user to reduce noise.

[0112] As a feasible implementation manner, please refer to Figure 16 The air conditioning system provided by the embodiment of the present application can also perform the following steps:

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

[0114] It should be understood that the embodiment of the present application does not specifically limit the way of obtaining data related to the user's living habits. For example, as a feasible implementation manner, the air conditioning system can determine the user's living habit data according to the user's operation of the air conditioning system.

[0115] As another feasible implementation manner, the air conditioning system can obtain the data sent by the sensor for detecting the sleep time and sleep stage of the human body as the user's living habit data.

[0116] As another feasible implementation manner, the air conditioning system can be connected with the terminal device of the user for data interaction, so that the user can set his / her sleep time, wake-up time, acceptable noise value, etc. on the terminal device, and then the air conditioning system obtains the data related to the user's living habits through the terminal device.

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

[0118] It can be understood that the sleep noise value is the maximum noise that the user can accept when sleeping, that is, if the air conditioning noise value exceeds the sleep noise value corresponding to the user, it will have a certain influence on the user.

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

[0120] Table 3

[0121]

[0122] It should be understood that the sleep time and the wake-up time shown in Table 3 are the corresponding sleep time period.

[0123] S603, when in the sleep time period corresponding to the user, determining whether the air conditioner noise value is above the sleep noise value.

[0124] When in the sleep time period corresponding to the user, it indicates that the user needs to sleep, and if the air conditioner noise value is too large, it will affect the user's rest. Therefore, it is determined whether the air conditioner noise value is above the sleep noise value, if yes, S704 is executed; if no, no processing is performed.

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

[0126] The operating frequency of the compressor is controlled to reduce a preset frequency, and / or the rotating speed of the fan is controlled to reduce a preset rotating speed, so that the air conditioner noise value is less than the sleep noise value corresponding to the user.

[0127] When in the sleep time period corresponding to the user, it indicates that the user needs to sleep, and if the air conditioner noise value is too large, it will affect the user's rest. Therefore, the operating frequency of the compressor is controlled to reduce a preset frequency, and / or the rotating speed of the fan is controlled to reduce a preset rotating speed, so that the air conditioner noise value is less than the sleep noise value corresponding to the user, avoiding that the air conditioner noise value affects the user's rest.

[0128] Since the rotating speed of the fan and the frequency of the compressor are the main factors affecting the air conditioner noise value, the air conditioner noise value can be reduced by reducing the rotating speed of the fan and the frequency of the compressor, so that the noise generated by the air conditioning system running is less than the sleep noise value corresponding to the user. The effect of air conditioning is taken into account while the air conditioner noise value does not affect the user.

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

[0130] Therefore, as a feasible implementation manner, the air conditioning system provided by the embodiment of the present application further comprises a temperature sensor for detecting the indoor temperature.

[0131] Please refer to​ The air conditioning system provided by the embodiments of the present application is further configured to:

[0132] S701, determining a time difference between a current time and a sleep time of a user.

[0133] The sleep time is a start time of a sleep time period corresponding to the user.

[0134] The time difference between the current time and the sleep time of the user is determined, that is, how long it is to the sleep time of the user.

[0135] S702, obtaining an indoor temperature when the time difference is less than or equal to a preset time.

[0136] It should be understood that the preset time is set by the system in advance, which can be set according to the needs in the actual application, and the embodiments of the present application do not make any limitation on this. For example, as a feasible implementation manner, the preset time is 30 minutes, and the indoor temperature is obtained when the time difference between the current time and the sleep time of the user is less than or equal to 30 minutes.

[0137] S703, if a temperature difference between the indoor temperature and a user-set temperature is greater than or equal to a preset temperature difference threshold, increasing a preset frequency of a running frequency of a compressor and / or increasing a preset rotating speed of a fan.

[0138] It should be understood that the preset temperature difference threshold is set by the system in advance, which can be set according to the needs in the actual application, and the embodiments of the present application do not make any limitation on this. For example, as a feasible implementation manner, the preset temperature difference threshold is 5 degrees Celsius, and the preset frequency of the running frequency of the compressor and / or the preset rotating speed of the fan are increased if the temperature difference between the indoor temperature and the user-set temperature is greater than or equal to 5 degrees Celsius.

[0139] When the distance to the sleep time period corresponding to the user is the preset time, if the temperature difference between the indoor temperature and the user-set temperature is greater than or equal to the preset temperature difference threshold, it indicates that the temperature (indoor temperature) of the space where the user is located cannot meet the user's demand, and the air conditioning system needs to speed up the refrigeration / heat to make the user space quickly reach the comfortable temperature required at the sleep time.

[0140] In this way, when the sleep time is reached, the temperature of the user space is still at the comfortable temperature, and the user will not immediately reduce the noise due to the sleep time, resulting in an uncomfortable temperature, thereby improving the user's experience.

[0141] In some embodiments, increasing the preset frequency of the operating frequency of the compressor and / or increasing the preset speed of the rotating speed of the fan may cause the air conditioner noise value to increase, and the increased noise value may affect the user experience, especially when the user is about to fall asleep (the time difference between the current time and the sleep time of the user is less than the preset time), the air conditioner noise value may affect the user's mood more.

[0142] As a feasible implementation manner, please refer to ​ The air conditioner system provided by the embodiment of the present application is further configured to, after S703:

[0143] S801, according to the air conditioner noise value and the environmental requirement value, adjusting the operating frequency of the compressor and / or the rotating 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 the preset noise threshold.

[0144] It should be understood that the preset noise threshold is pre-set by the system, which can be set according to the demand in the actual application, and the embodiment of the present application does not make any limitation.

[0145] As a feasible implementation manner, 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 reduced by the preset frequency, and / or the rotating speed of the fan is reduced by the preset speed. 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 manner, 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 increased by the preset frequency, and / or the rotating speed of the fan is increased by the preset speed. To improve the refrigeration / heating capacity of the air conditioner system, so that the indoor temperature quickly reaches the comfortable temperature required at the sleep time.

[0147] It should be understood that, as a feasible implementation manner, please refer to ​ After S604, the air conditioner system provided by the embodiment of the present application is further configured to:

[0148] S901, when reaching the getting-up time, adjusting the air conditioner operation state according to the environmental noise value and the air conditioner noise value.

[0149] When reaching the getting-up time of the user, the user's requirement for noise may be slightly lower, and the slightly larger air conditioner noise value will not affect the user, so the air conditioner operation state is adjusted according to the environmental noise value and the air conditioner noise value, so that the air conditioner system restores the normal refrigeration / heating capacity.
