Description

Technical Field

[0001] This application relates to the field of air conditioning control, specifically to an air conditioning control method, apparatus, equipment, and storage medium. Background Technology

[0002] Currently, with the rapid development of air conditioners, more and more users are using air conditioners for cooling or heating. However, in existing air conditioning refrigeration systems, high-temperature and high-pressure refrigerant is discharged from the compressor and then throttled into a low-temperature and low-pressure liquid through a throttling device. This liquid then enters the indoor pipes through the indoor unit connecting pipes. After passing through the indoor evaporator, the evaporator absorbs heat and transforms the low-temperature and low-pressure liquid into a low-temperature and low-pressure gas. After passing through the distributor, some refrigeration systems, in order to meet specific operating conditions, often charge too much refrigerant, resulting in failure to meet low-load cooling conditions. Under low-load conditions, this leads to a large amount of refrigerant entering the indoor unit evaporator. Incomplete refrigerant evaporation produces a large number of bubbles. These bubbles absorb heat and burst, resulting in liquid flow noise on the indoor side of the air conditioner, which makes the comfort and stability of the air conditioner poor. Summary of the Invention

[0010] If the indoor unit noise data is greater than the preset noise value, then the noise type of the indoor unit noise data is determined to be liquid flow noise type;

[0011] If the indoor unit noise data is less than the preset noise value, then the noise type of the indoor unit noise data is determined to be non-fluid flow noise type.

[0012] In one possible implementation of this application, the step of determining the noise type of the indoor unit noise data as liquid flow noise type if the indoor unit noise data is greater than the preset noise value includes:

Therefore, the invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0052] Currently, with the rapid development of air conditioners, more and more users are using air conditioners for cooling or heating. However, in existing air conditioning refrigeration systems, high-temperature and high-pressure refrigerant is discharged from the compressor and then throttled into a low-temperature and low-pressure liquid through a throttling device. This liquid then enters the indoor pipes through the indoor unit connecting pipes. After passing through the indoor evaporator, the evaporator absorbs heat and transforms the low-temperature and low-pressure liquid into a low-temperature and low-pressure gas. After passing through the distributor, some refrigeration systems, in order to meet specific operating conditions, often charge too much refrigerant, resulting in failure to meet low-load cooling conditions. Under low-load conditions, this leads to a large amount of refrigerant entering the indoor unit evaporator. Incomplete refrigerant evaporation produces a large number of bubbles. These bubbles absorb heat and burst, resulting in liquid flow noise on the indoor side of the air conditioner, which makes the comfort and stability of the air conditioner poor.

[0053] Based on this, this application proposes an air conditioning control method, apparatus, device, and computer-readable storage medium to solve the technical problem in the prior art where air conditioning generates liquid flow noise during operation, resulting in poor air conditioning comfort and stability.

The air conditioning control equipment can be an intelligent terminal or MCU for controlling various types of air conditioners such as portable air conditioners, window air conditioners, wall-mounted air conditioners, and floor-standing air conditioners.

[0055] like Figure 1 As shown, Figure 1This is a schematic diagram of a scenario illustrating the air conditioning control method according to an embodiment of this application. The air conditioning control scenario in this embodiment includes an air conditioning control device 100 (which integrates an air conditioning control unit) and a target air conditioner 200. The air conditioning control device 100 has a computer-readable storage medium corresponding to the air conditioning control method running to execute the steps of the air conditioning control method. The target air conditioner can be various types of air conditioners, such as portable air conditioners, window air conditioners, wall-mounted air conditioners, and floor-standing air conditioners.

[0056] Understandable, Figure 1 The air conditioning control device in the air conditioning control method scenario shown, or the device included in the air conditioning control device, does not constitute a limitation on the embodiments of the present invention. That is, the number or type of air conditioning control device included in the air conditioning control method scenario, or the number or type of device included in each device, does not affect the overall implementation of the technical solution in the embodiments of the present invention, and can all be considered as equivalent substitutions or derivatives of the technical solutions claimed in the embodiments of the present invention.

[0057] In this embodiment of the invention, the air conditioning control device 100 is mainly used to: respond to an air conditioning control request and obtain the target air conditioning setting of the target air conditioner corresponding to the air conditioning control request;

[0058] Collect indoor unit noise data corresponding to the target air conditioner setting, and determine the noise type of the indoor unit noise data based on the indoor unit noise data and a preset noise value;

[0059] If the noise type is a liquid flow noise type, then obtain the noise cancellation strategy corresponding to the liquid flow noise type, and correct the target air conditioning setting of the target air conditioner according to the noise cancellation strategy.

[0060] The air conditioning control device 100 in this embodiment of the invention can be an independent air conditioning control device, such as a mobile phone, tablet computer, network device and smart computer, or it can be a processing module built into the air conditioner.

[0061] This application provides an air conditioning control method, apparatus, air conditioner, and computer-readable storage medium, which will be described in detail below.

[0062] It will be understood by those skilled in the art that Figure 1 The application environment shown is only one application scenario related to the solution of this application and does not constitute a limitation on the application scenario of this application. Other application environments may include more than one application scenario.

It can be understood that the scenario of the air conditioning control method may also include one or more air conditioning control devices, which are not limited here. The air conditioning control device 100 may also include a memory for storing preset noise values ​​and other data.

[0063] It should be noted that, Figure 1 The schematic diagram of the air conditioning control method shown is merely an example. The scenarios of the air conditioning control method described in the embodiments of the present invention are intended to more clearly illustrate the technical solutions of the embodiments of the present invention and do not constitute a limitation on the technical solutions provided in the embodiments of the present invention.

[0064] Based on the scenarios described above for air conditioning control methods, various embodiments of the air conditioning control method disclosed in this invention are proposed.

[0065] like Figure 2 As shown, Figure 2 This is a flowchart illustrating one embodiment of the air conditioning control method in this application. The air conditioning control method includes the following steps 201 to 203:

[0066] 201. Respond to the air conditioning control request and obtain the target air conditioning setting of the target air conditioner corresponding to the air conditioning control request;

[0067] The air conditioning control method in this embodiment is applied to an air conditioning control device. The type and number of air conditioning control devices are not specifically limited. That is, the air conditioning control device can be an intelligent terminal for controlling the operating status of one or more portable air conditioners, window air conditioners, wall-mounted air conditioners, and cabinet air conditioners. Optionally, the air conditioning control device can also be a control module built into the air conditioner.

[0068] Specifically, the air conditioning control equipment is configured to detect noise in the target air conditioner when it is running, and to adjust the operating level of the target air conditioner based on the noise detection results, thereby reducing the air conditioning liquid flow noise caused by incomplete refrigerant evaporation during the operation of the target air conditioner.

[0069] Specifically, during operation, the air conditioning control equipment responds to air conditioning control requests, which are operational instructions that drive the air conditioning control equipment to eliminate noise from the target air conditioner. Optionally, the triggering method for this air conditioning control request is not specifically limited. For example, the air conditioning control request can be triggered actively by the user, such as when the user notices liquid flow noise and actively triggers the air conditioning control request to the air conditioning control equipment. Optionally, the air conditioning control request can also be automatically triggered by the air conditioning control equipment, for example, the air conditioning control equipment can be pre-set with a timed detection process to automatically trigger the air conditioning control request within a preset time period or preset operating mode.

[0070] Specifically, after receiving an air conditioning control request, the air conditioning control device parses the request and obtains the target air conditioning setting of the target air conditioner corresponding to the request.

[0071] Specifically, to avoid the refrigerant in the target air conditioner from incompletely evaporating and generating a large number of bubbles that absorb heat and burst, resulting in liquid flow noise, the air conditioning control equipment detects the target air conditioning setting after detecting it. It then detects the fan speed at that target setting and compares it with the preset silent speed threshold to determine if the target air conditioning setting corresponds to the low-load cooling condition.

[0072] Optionally, if the fan speed of the target air conditioner setting is greater than the silent speed threshold, the air conditioning control device determines that the operating condition of the target air conditioner setting is a medium-high load cooling condition. Under this medium-high load cooling condition, the user cannot perceive most of the liquid flow noise, and there is no need to adjust the target air conditioner setting.

[0073] Optionally, if the fan speed of the target air conditioner setting is less than or equal to the silent speed threshold, the air conditioning control equipment determines that the operating condition of the target air conditioner setting is a low-load cooling condition, and it is necessary to detect and eliminate the liquid flow noise of the target air conditioner setting.

[0074] After the air conditioning control equipment detects that the fan speed of the target air conditioner is less than or equal to the silent speed threshold, it calls the preset audio detection module to detect the noise of the target air conditioner in order to obtain the noise data of the indoor unit of the target air conditioner.

[0075] 202. Collect the indoor unit noise data corresponding to the target air conditioner setting, and determine the noise type of the indoor unit noise data based on the indoor unit noise data and the preset noise value;

[0076] Specifically, after the target air conditioner is powered on and started, the air conditioning control equipment responds in advance to the fan speed control request, drives the target air conditioner to operate at the test air conditioning setting corresponding to the fan speed control request, and collects the test noise data and test liquid flow noise data corresponding to the test air conditioning setting to generate a preset noise value for the test air conditioning setting, and stores the preset noise value in a preset liquid flow noise database. In one specific embodiment, the liquid flow noise data is 3dB (unit: decibel), and the test noise data is the air supply noise data of the target air conditioner under test conditions.

[0077] Specifically, after receiving an air conditioning control request, the air conditioning control device collects the compressor start-up time of the target air conditioner. If the compressor start-up time exceeds a preset start-up time threshold, it calls a preset audio detection module to perform noise detection on the target air conditioner. This collects indoor unit noise data corresponding to the target air conditioning setting and determines the noise type of the indoor unit noise data based on the indoor unit noise data and a preset noise value corresponding to the target air conditioning setting in the liquid flow noise database. The preset start-up time threshold is a start-up duration threshold set to avoid false detections; in one specific embodiment, the preset start-up time threshold is 180 seconds. The preset noise value is the audio data threshold for detecting whether the noise type of the target air conditioning setting is a liquid flow noise type.

[0078] Specifically, after obtaining the indoor noise data corresponding to the target air conditioner at the target air conditioning setting, the air conditioning control equipment compares the indoor noise data with the preset noise value to determine the noise type of the indoor unit.

[0079] Optionally, if the indoor unit noise data is less than the preset noise value, the air conditioning control device determines that the indoor noise data is not liquid flow noise caused by the bursting of bubbles due to incomplete refrigerant evaporation. The air conditioning control device determines that the noise type of the indoor unit noise data is non-liquid flow noise and determines that there is no need to perform noise cancellation operation on the target air conditioning setting.

[0080] Optionally, if the indoor unit noise data is greater than or equal to the preset noise value, the air conditioning control device determines that the target air conditioner has liquid flow noise caused by incomplete refrigerant evaporation leading to bubble rupture under the target air conditioning setting. Therefore, the air conditioning control device determines that the noise type of the indoor unit noise data is liquid flow noise and needs to perform liquid flow noise elimination processing on the target air conditioner.

[0081] 203. If the noise type is a liquid flow noise type, then obtain the noise cancellation strategy corresponding to the liquid flow noise type, and correct the target air conditioning setting of the target air conditioner according to the noise cancellation strategy.

[0082] After the air conditioning control equipment detects that the noise data of the indoor unit is greater than or equal to the preset noise value and determines that the noise type is liquid flow noise, it also obtains the noise cancellation strategy corresponding to the liquid flow noise type, and corrects the opening degree of the electronic expansion valve and the angle of the air guide plate in the target air conditioning setting of the target air conditioner according to the noise cancellation strategy, thereby reducing the liquid flow noise of the target air conditioner in the target air conditioning setting.

[0083] Specifically, the air conditioning control equipment accesses a preset database, inputs the liquid flow noise type and the target air conditioning setting into the preset database for strategy query, and obtains the noise cancellation strategy in the preset database that matches the liquid flow noise type and the target air conditioning setting.

[0084] Specifically, after acquiring the noise cancellation strategy, the air conditioning control device obtains the opening correction frequency and preset correction time in the noise cancellation strategy, and corrects the opening of the electronic expansion valve and the angle of the air guide plate of the target air conditioner according to the opening correction frequency and preset correction time. Optionally, in a specific embodiment, the opening correction frequency in the noise cancellation strategy is 10B / 60s, and the preset correction time is 60 seconds. The air conditioning control device reduces the opening of the electronic expansion valve of the target air conditioner at a frequency of 10B / 60s, thereby controlling the amount of refrigerant flowing into the indoor side, increasing the evaporative superheat, and allowing the liquid refrigerant to completely evaporate in the evaporator of the target air conditioner, thereby reducing the liquid flow noise.

[0085] Specifically, the air conditioning control equipment also controls the angle of the air guide vane of the target air conditioner, thereby further reducing the liquid flow noise of the target air conditioner.

[0086] In this embodiment, the air conditioning control device responds to an air conditioning control request and obtains the target air conditioning setting of the target air conditioner corresponding to the control request; it collects indoor unit noise data corresponding to the target air conditioning setting, and determines the noise type of the indoor unit noise data based on the indoor unit noise data and a preset noise value; if the noise type is a liquid flow noise type, it obtains the noise cancellation strategy corresponding to the liquid flow noise type, and corrects the target air conditioning setting of the target air conditioner according to the noise cancellation strategy. This achieves the goal of accurately determining the noise type of the target air conditioner by detecting its operating noise, and promptly correcting the air conditioning setting based on the noise type, thereby reducing air conditioning operating noise and improving air conditioning comfort and stability.

[0087] like Figure 3 As shown, Figure 3 This is a flowchart illustrating an embodiment of the air conditioning control method provided in this application for correcting the target air conditioning setting. Specifically, it includes steps 301 to 303:

[0088] 301. Correct the opening of the electronic expansion valve of the target air conditioner according to the opening correction frequency and the preset correction time, and collect the correction noise data of the target air conditioner;

[0089] 302. If the corrected noise data is greater than the preset corrected noise threshold and the opening of the electronic expansion valve of the target air conditioner is the preset minimum opening, then obtain the preset fan speed and guide vane correction angle corresponding to the corrected noise data.

[0090] 303. Noise correction is performed on the target air conditioner based on the preset fan speed and the correction angle of the air guide plate.

[0091] Based on the above embodiments, in this embodiment, the air conditioning control device corrects the noise of the electronic expansion valve opening of the target air conditioner according to the opening correction frequency and preset correction time. After correction, it also calls the preset audio detection module to collect the corrected noise data of the target air conditioner and detects the corrected noise data to determine the noise correction result of the target air conditioner.

[0092] Specifically, after acquiring the corrected noise data, the air conditioning control equipment compares the corrected noise data with the preset corrected noise threshold to determine the noise correction result of the target air conditioner.

[0093] Optionally, if the corrected noise data is less than the preset corrected noise threshold, the air conditioning control device determines that the air supply noise of the target air conditioner can cover the liquid flow noise, and the air conditioning control device outputs a correction completion notification.

[0094] Optionally, if the corrected noise data is greater than or equal to the preset corrected noise threshold, the air conditioning control device determines that the target air conditioner still has liquid flow noise. The air conditioning control device then performs a second correction on the target air conditioner according to the opening correction frequency and the preset correction time, until the opening of the electronic expansion valve of the target air conditioner is the preset minimum opening.

[0095] Specifically, if the corrected noise data is still greater than the corrected noise threshold, and the electronic expansion valve opening of the target air conditioner is the preset minimum opening, the air conditioning control device obtains the preset fan speed and air guide plate correction angle corresponding to the corrected noise data, and performs noise correction on the target air conditioner according to the preset fan speed and air guide plate correction angle.

[0096] Specifically, the air conditioning control equipment increases the current fan speed of the target air conditioning setting according to the preset fan speed, and drives the air guide plate to close upward according to the correction angle of the air guide plate, so as to reduce the air outlet angle, accelerate the evaporation of refrigerant on the indoor side, so that the refrigerant on the indoor side becomes as gaseous as possible, reduce liquid flow noise, and reduce the noise of the fan deflector.

[0097] Specifically, after the air conditioning control equipment corrects the noise by setting the fan speed and the air guide plate angle, it also detects the comparison between the corrected noise data and the corrected noise threshold. If the corrected noise data is less than the corrected noise threshold, it outputs a correction completion notification.

[0098] In this embodiment, the air conditioning control device corrects the opening of the electronic expansion valve of the target air conditioner according to the opening correction frequency and the preset correction time, and collects the corrected noise data of the target air conditioner. If the corrected noise data is greater than a preset corrected noise threshold and the opening of the electronic expansion valve of the target air conditioner is a preset minimum opening, then a preset fan speed and guide vane correction angle corresponding to the corrected noise data are obtained. Noise correction is performed on the target air conditioner according to the preset fan speed and guide vane correction angle. This reduces the operating noise of the air conditioner and improves its comfort and stability.

[0099] like Figure 4 As shown, Figure 4 This is a flowchart illustrating an embodiment of the air conditioning control method for determining the noise type of indoor unit noise data provided in this application, specifically including steps 401 to 403:

[0100] 401. If the indoor unit noise data is greater than the preset noise value, then perform audio analysis on the indoor unit noise data to obtain the noise characteristic spectrum;

[0101] 402. Match the noise characteristic spectrum with the preset liquid flow noise spectrum range to obtain the target indoor unit noise data whose noise characteristic spectrum falls within the liquid flow noise spectrum range;

[0102] 403. Mark the noise type of the target indoor unit noise data as liquid flow noise type.

[0103] Based on the above embodiments, in this embodiment, after comparing the indoor unit noise data with the preset noise value, the air conditioning control device also performs noise type detection based on the comparison result and the noise characteristic spectrum.

[0104] Specifically, after detecting that the indoor unit noise data exceeds the preset noise value, the air conditioning control equipment determines that the indoor unit noise data also includes other interfering noises besides the air supply noise. The air conditioning control equipment performs audio analysis on the indoor unit noise data to obtain the noise characteristic spectrum of the indoor unit noise data.

[0105] After acquiring the noise characteristic spectrum of the indoor unit noise data, the air conditioning control equipment matches the noise characteristic spectrum with the preset liquid flow noise spectrum range to determine whether liquid flow noise exists in the indoor unit noise data.

[0106] Optionally, if the noise characteristic spectrum of the indoor unit noise data does not match the liquid flow noise spectrum range, that is, the noise characteristic spectrum does not fall within the liquid flow noise spectrum range, the air conditioning control device determines that the noise type of the indoor unit noise data is a non-liquid flow noise type.

[0107] Optionally, if the noise characteristic spectrum of the indoor unit noise data matches the liquid flow noise spectrum range, that is, the noise characteristic spectrum falls within the liquid flow noise spectrum range, then the air conditioning control device determines that the noise type of the indoor unit noise data is the liquid flow noise type, and it is necessary to perform liquid flow noise correction on the target air conditioner to eliminate the liquid flow noise.

[0108] Specifically, the air conditioning control equipment accesses a preset database, inputs the liquid flow noise type and the target air conditioning setting into the database for strategy query, and retrieves the noise cancellation strategy that matches the liquid flow noise type and the target air conditioning setting from the preset database. Noise correction is then performed on the target air conditioner at the target air conditioning setting according to this noise cancellation strategy.

[0109] In this embodiment, the air conditioning control device detects that if the indoor unit noise data exceeds a preset noise value, it performs audio analysis on the indoor unit noise data to obtain a noise characteristic spectrum. The noise characteristic spectrum is then matched with a preset liquid flow noise spectrum range to obtain target indoor unit noise data whose noise characteristic spectrum falls within the liquid flow noise spectrum range. The noise type of the target indoor unit noise data is then labeled as a liquid flow noise type. This achieves accurate identification of air conditioning noise types, enabling targeted reduction of air conditioning operating noise and improving air conditioning comfort and stability.

[0110] To better implement the air conditioning control method in the embodiments of this application, an air conditioning control device is also provided in the embodiments of this application, such as...

[0113] The noise correction module 503 is configured to, if the noise type is a liquid flow noise type, obtain the noise cancellation strategy corresponding to the liquid flow noise type, and correct the target air conditioning setting of the target air conditioner according to the noise cancellation strategy.

[0114] In one possible implementation of this embodiment, the air conditioning control device collects indoor unit noise data corresponding to the target air conditioning setting, and determines the noise type of the indoor unit noise data based on the indoor unit noise data and a preset noise value, including:

[0115] Collect the indoor unit noise data of the target air conditioner at the target air conditioning setting, and compare the indoor unit noise data with the preset noise value corresponding to the target air conditioning setting;

[0116] If the indoor unit noise data is greater than the preset noise value, then the noise type of the indoor unit noise data is determined to be liquid flow noise type;

[0117] If the indoor unit noise data is less than the preset noise value, then the noise type of the indoor unit noise data is determined to be non-fluid flow noise type.

[0118] In one possible implementation of this embodiment, if the noise data of the indoor unit is greater than the preset noise value, the air conditioning control device determines that the noise type of the indoor unit noise data is a liquid flow noise type, including:

[0121] The noise type of the target indoor unit noise data is labeled as liquid flow noise type.

[0134] The fan speed of the target air conditioner setting is compared with the silent speed threshold of the preset silent setting.

[0135] If the fan speed of the target air conditioner is less than or equal to the silent speed threshold, then the preset audio detection module is invoked to detect the noise of the target air conditioner and obtain the noise data of the indoor unit.

This achieves the goal of accurately determining the noise type of the target air conditioner by detecting its operating noise, and promptly correcting the air conditioning setting based on the noise type, thereby reducing air conditioning operating noise and improving air conditioning comfort and stability.
