Technical Field

[0001] This application relates to the field of air conditioning, and more particularly to a control method, apparatus, air conditioning unit, and storage medium for an air conditioning unit. Background Technology

[0002] With the development of artificial intelligence technology and the continuous innovation of home appliance technology, people's demands for comfort and cost-effectiveness are constantly increasing. To achieve this while increasing intelligent functions, there are currently two extreme design approaches: one is to keep the number of operation buttons on the handheld device unchanged and add more buttons to activate corresponding functions; the other is to add more buttons to the handheld device, making the operation appear cluttered and disorganized.

[0003] The original purpose of air conditioners was to solve people's cooling and heating needs. As air conditioners have been upgraded and replaced, they are becoming more and more intelligent, but the way they are operated has also become more and more complicated, resulting in cumbersome control methods. Summary of the Invention

[0005] In a first aspect, this application provides a control method for an air conditioning unit, the method comprising:

[0006] After detecting that the unit is powered on, the control unit enters the initialization mode, which includes either the cooling mode or the heating mode.

[0007] During the initialization mode operation, the unit switches to the control mode corresponding to the single button selected by the user. The control mode includes comfort mode, energy-saving mode or custom mode. During the operation of comfort mode or energy-saving mode, the unit automatically adjusts the parameters.

[0008] Optionally, the automatic parameter adjustment of the comfort mode includes:

[0009] Obtain the user-set temperature in the comfort mode;

[0010] Determine whether the set temperature is within the range of human comfort.

[0011] If the position is within the range of human comfort, the unit parameters are adjusted according to the first adjustment scheme.

[0012] If the parameters are not within the range of human comfort, the unit parameters will be adjusted according to the second adjustment scheme.

[0013] Optionally, adjusting the unit parameters according to the first adjustment scheme includes:

[0014] In cooling mode, the temperature difference between the current ambient temperature and the set temperature is determined;

[0015] If the temperature difference remains greater than the first cooling temperature threshold for a set period of time, the low pressure correction value is adjusted, wherein adjusting the low pressure correction value refers to reducing the current evaporator-side refrigerant saturation temperature.

[0016] If the temperature difference remains between the second cooling temperature threshold and the first cooling temperature threshold for a set period of time, the adjusted low-pressure correction value is maintained.

[0017] If the temperature difference remains below the second cooling temperature threshold for a set period of time, the low-pressure correction value is reset to zero.

[0018] Optionally, adjusting the unit parameters according to the first adjustment scheme includes:

[0019] In heating mode, the temperature difference between the current ambient temperature and the set temperature is determined;

[0020] If the temperature difference remains below the first heating temperature threshold for a set period of time, the high pressure correction value is adjusted, wherein adjusting the high pressure correction value refers to increasing the current refrigerant saturation temperature on the condensing side.

[0021] If the temperature difference remains between the first heating temperature threshold and the second heating temperature threshold for a set period of time, the adjusted high pressure correction value is maintained.

[0022] If the temperature difference remains greater than the second heating temperature threshold for a set period of time, the high pressure correction value is reset to zero.

[0023] Optionally, adjusting the unit parameters according to the second adjustment scheme includes:

[0024] In cooling mode, the temperature difference between the current ambient temperature and the set temperature is determined;

[0025] If the temperature difference remains greater than the third cooling temperature threshold for a set period of time, the first unit parameter is controlled to be output with an increased amplitude, wherein the first unit parameter is used to reduce the current ambient temperature.

[0026] If the temperature difference remains within the preset temperature range for a set period of time, the parameters of the first unit are maintained.

[0027] If the temperature difference remains less than the fourth cooling temperature threshold for a set period of time, the parameters of the first unit are controlled to be output with a reduced amplitude, wherein the third cooling temperature threshold is greater than the value in the preset temperature range, and the value in the preset temperature range is greater than the fourth cooling temperature threshold.

[0033] Optionally, the parameter adjustment of the energy-saving mode includes:

[0034] Determine the temperature difference between the current ambient temperature and the set temperature;

[0035] In cooling mode, if the temperature difference is continuously less than the minimum cooling difference, the low pressure correction value is increased. The increase of the low pressure correction value refers to increasing the current refrigerant saturation temperature on the evaporator side.

[0036] Once the ambient temperature reaches the set temperature, the increased low-pressure correction value is reset to zero.

[0037] Optionally, the parameter adjustment of the energy-saving mode includes:

[0038] Determine the temperature difference between the current ambient temperature and the set temperature;

[0039] In heating mode, if the temperature difference is continuously less than the minimum heating difference, the high pressure correction value is reduced. The reduction of the high pressure correction value refers to reducing the current refrigerant saturation temperature on the condensing side.

[0040] Once the ambient temperature reaches the set temperature, the reduced high-pressure correction value is reset to zero.

[0041] Optionally, the control unit entering the initialization mode includes:

[0042] If the unit is detected to be powered on for the first time, it will enter the initialization mode based on the current season and the current outdoor temperature.

[0049] The switching module is used to switch to the control mode corresponding to a single button selected by the user during the operation of the initialization mode. The control mode includes a comfort mode, an energy-saving mode, or a custom mode. During the operation of the comfort mode or the energy-saving mode, the unit automatically adjusts the parameters.

[0050] Thirdly, this application provides a terminal / device / server for adjusting the opening degree of an air conditioning electronic expansion valve, comprising: at least one communication interface; at least one bus connected to the at least one communication interface; at least one processor connected to the at least one bus; and at least one memory connected to the at least one bus.

[0052] Compared with the prior art, the above-mentioned technical solution provided in this application has the following advantages: the air conditioning unit first enters the cooling or heating mode, and performs cooling or heating in advance. Then, according to the user's habits, the control mode can be switched with one key, which is convenient to operate. There is no need to operate multiple buttons on the hand controller, nor is it necessary to increase the number of buttons on the hand controller. This solves the problems of complex, inhumane and unintelligent operation of the hand controller. This application simplifies the operation of the air conditioner. Attached Figure Description

[0063] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0064] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0065] This application provides a control method for an air conditioning unit, which can be applied to servers, such as... Figure 1 As shown, the method includes:

[0066] Step 101: After detecting that the unit is powered on, control the unit to enter the initialization mode. The initialization mode includes either cooling mode or heating mode.

[0067] After the server detects that the air conditioning unit is powered on, it first controls the unit to enter either cooling or heating mode. Whether it is cooling or heating can be determined according to the specific situation, and the determination method will be described below, so it will not be repeated here.

[0068] Step 102: During the initialization mode operation, switch to the control mode corresponding to the single button selected by the user.

[0069] The control modes include comfort mode, energy-saving mode, or custom mode. During operation in comfort mode or energy-saving mode, the unit automatically adjusts the parameters.

[0070] During the initialization mode operation, users can switch control modes with one click according to their habits. That is, they can switch from the initialization mode to comfort mode, energy-saving mode or custom mode with one click.

[0071] During operation in either Comfort or Energy-Saving mode, the unit automatically adjusts its parameters. Comfort mode controls the unit to rapidly heat up or cool down when the current ambient temperature differs significantly from the set temperature, and maintains minimal temperature fluctuations when the difference is small, ensuring user comfort. Energy-Saving mode aims to conserve energy while maintaining user comfort.

[0072] User needs are diverse, and if the above two functions are not met, a custom mode can be activated with one click. Custom mode allows users to choose their own operating control mode. When a user selects custom mode, a control operation page appears, allowing the user to select and confirm the settings for each function to meet their customized needs.

[0073] Figure 2The diagram shows the interface for switching air conditioning control modes. As you can see, in custom mode, you can continue to adjust the temperature, mode, and fan speed, while in energy-saving mode, only the operating parameters are displayed.

[0074] In this application, the air conditioning unit first enters the cooling or heating mode to pre-cool or heat, and then switches the control mode with one key according to the user's habits. This makes the operation convenient and does not require the operation of multiple buttons on the hand controller, nor does it require increasing the number of buttons on the hand controller. This solves the problems of complicated, unintuitive, and unintelligent operation of the hand controller. This application simplifies the operation of the air conditioner.

[0075] There are two scenarios when the control unit enters the initialization mode.

[0076] In the first scenario, when the unit is powered on for the first time, which is the first time the intelligent selection (AI mode) of the control mode is used, the server controls the unit to enter the initialization mode based on the current season and the current outdoor temperature.

[0077] For example, seasonal determination: a. Cooling season: June 1st - September 31st; b. Heating season: December 1st - March 31st; c. Transitional season: other months. Generally, heating mode should be activated during the cooling season and cooling mode during the heating season. However, due to the different seasons in different regions, such as the different hot and cold months in the Northern and Southern Hemispheres, and even the different hot and cold months in different provinces and cities, it is necessary to combine the current season and the current outdoor temperature to determine whether to use heating or cooling.

[0078] In the second scenario, if the unit is not being powered on for the first time, meaning it is not using the intelligent selection (AI mode) of this control mode for the first time, the system will determine the current season. If it is summer (cooling season) or winter (heating season), it will enter the initialization mode based on the historical operating mode of the same season in the previous year.

[0079] The historical operating mode of the same season in the previous year can be the operating mode of the last unit used in the same season in the previous year, the operating mode at a similar temperature in the same season in the previous year, or the operating mode on the same day in the same season in the previous year. This application does not limit this.

[0080] If it is spring or autumn (transitional season), determine whether the user turned on the air conditioner before the preset time period. For example, if the user turned on the air conditioner 5 days ago, if so, maintain the previous operating mode; if not, enter the initialization mode based on the current outdoor temperature.

[0081] Figure 3This is a flowchart illustrating the cooling or heating process of the unit. It shows that during the cooling or heating season, if the unit is using AI mode for the first time, it will directly switch to cooling or heating. If this is not the first time the unit has used AI mode, it will maintain the previous control mode. During transitional seasons, it is necessary to determine whether the air conditioner was turned on 5 days prior. If it was, the original mode will be maintained; if not, the outdoor ambient temperature will determine whether to cool or heat.

[0082] This solution can be applied to multi-split air conditioners. Generally, the control mode of each indoor unit in a multi-split air conditioner is the same as that of the main indoor unit. If the indoor unit used in the current solution is not the main indoor unit, then if there is no conflict between the initialization mode and the main indoor unit mode, the initialization mode will be used. If there is a conflict between the initialization mode and the main indoor unit mode, the initialization mode will be used, and the main indoor unit mode will be changed to be consistent with the initialization mode.

[0083] As an optional implementation, the automatic parameter adjustment in comfort mode includes: acquiring the user-set temperature in comfort mode; determining whether the set temperature is within the human comfort range; if it is within the human comfort range, adjusting the unit parameters according to a first adjustment scheme; if it is not within the human comfort range, adjusting the unit parameters according to a second adjustment scheme. By operating comfort mode, the user's environmental comfort requirements can be met as quickly as possible.

[0084] The user sets the set temperature, and the unit determines whether the set temperature is within the range where the human body feels comfortable. Generally speaking, the range where the human body feels comfortable is between 23℃ and 26℃.

[0085] If the set temperature is within the range of human comfort, for example, a set temperature of 25℃, the unit parameters will be adjusted according to the first adjustment scheme. The first adjustment scheme is further divided into cooling mode or heating mode.

[0086] First adjustment plan:

[0087] 1. In cooling mode, determine the temperature difference between the current ambient temperature and the set temperature; if the temperature difference is continuously greater than the first cooling temperature threshold within the set time, adjust the low-pressure correction value, where adjusting the low-pressure correction value refers to lowering the current evaporator-side refrigerant saturation temperature; if the temperature difference is continuously between the second cooling temperature threshold and the first cooling temperature threshold within the set time, maintain the adjusted low-pressure correction value; if the temperature difference is continuously less than the second cooling temperature threshold within the set time, reset the low-pressure correction value to zero.

[0088] The evaporator is where the refrigerant absorbs heat and evaporates from a liquid state to a gaseous state. The saturation temperature of the evaporator is when its temperature drops below a certain threshold, preventing further evaporation. If the temperature difference Δt remains greater than the first cooling temperature threshold for a set period, it indicates that the current ambient temperature is too high. Lowering the refrigerant saturation temperature on the evaporator side can increase the cooling rate, ensuring rapid cooling to reach the user's set temperature and meet their needs.

[0089] If the temperature difference Δt remains between the second and first cooling temperature thresholds within the set time period, it indicates that the current ambient temperature and the set temperature are not significantly different, and the cooling can continue according to the low-pressure correction value.

[0090] If the temperature difference Δt remains less than the second cooling temperature threshold within the set time, it indicates that the current ambient temperature and the set temperature are very close. At this time, the correction value can be reset to zero, and the ambient temperature can be brought up to the set temperature according to the conventional evaporator-side refrigerant saturation temperature.

[0091] For example, in cooling mode, if Δt ≥ 5℃ is detected for 8 minutes, the target low pressure is corrected by -1 each time; if 2℃ ≤ Δt < 5℃ is detected for 8 minutes, the current low pressure correction value is maintained and no further correction is allowed; if Δt < 2℃ is detected for 8 minutes, the low pressure correction value is reset to zero. If the target low pressure is detected to be ≤ 0℃ during the initial detection or operation, no correction is allowed.

[0092] 2. In heating mode, determine the temperature difference between the current ambient temperature and the set temperature; if the temperature difference remains less than the first heating temperature threshold within the set time, adjust the high-pressure correction value, where adjusting the high-pressure correction value refers to increasing the current condenser side refrigerant saturation temperature; if the temperature difference remains between the first heating temperature threshold and the second heating temperature threshold within the set time, maintain the adjusted high-pressure correction value; if the temperature difference remains greater than the second heating temperature threshold within the set time, reset the high-pressure correction value to zero.

[0093] The condenser is where the refrigerant releases heat and condenses from a gaseous state into a liquid state. The condenser's saturation temperature is the temperature at which the refrigerant can no longer condense. If the temperature difference remains below the first heating temperature threshold for a set period, it indicates that the current ambient temperature is too low. By increasing the current refrigerant saturation temperature on the condenser side, the heating rate can be increased, ensuring the air conditioner quickly reaches the user's set temperature and meets their needs.

[0094] If the temperature difference remains between the first heating temperature threshold and the second heating temperature threshold within the set time period, it indicates that the current ambient temperature and the set temperature are not significantly different, and the temperature can continue to rise according to the high-pressure correction value.

[0095] If the temperature difference remains greater than the second heating temperature threshold for a set period of time, it indicates that the current ambient temperature and the set temperature are very close. At this time, the correction value can be reset to zero, and the ambient temperature can be brought up to the set temperature according to the conventional condenser side refrigerant saturation temperature.

[0096] For example, in heating mode, if Δt ≤ -5℃ is detected for 8 minutes, the target high pressure is corrected by +1 each time; if -5℃ ≤ Δt < -2℃ is detected for 8 minutes, the high pressure correction value is maintained and cannot be corrected further; if Δt > -2℃ is detected for 8 minutes, the high pressure correction value is reset to zero. If the target high pressure is detected to be ≥ 51℃ during the first detection or during operation, it cannot be revised.

[0097] Figure 4 This is a flowchart illustrating the comfort mode.

[0098] If the set temperature is not within the range of human comfort, the unit parameters will be adjusted according to the second adjustment scheme. The second adjustment scheme is further divided into cooling mode or heating mode.

[0099] Second adjustment plan:

[0100] 1. In cooling mode, determine the temperature difference between the current ambient temperature and the set temperature; if the temperature difference is continuously greater than the third cooling temperature threshold within the set time, control the first unit parameter to output with an increased amplitude, wherein the first unit parameter is used to lower the current ambient temperature; if the temperature difference is continuously within the preset temperature range within the set time, maintain the first unit parameter; if the temperature difference is continuously less than the fourth cooling temperature threshold within the set time, control the first unit parameter to output with a decreased amplitude, wherein the third cooling temperature threshold is greater than the value in the preset temperature range, and the value in the preset temperature range is greater than the fourth cooling temperature threshold.

[0101] For example, the current ambient temperature is 34°C, and the set temperature is 18°C. 18°C ​​is below the range of human comfort. If the current ambient temperature drops to 30°C, the indoor comfort is still poor. Increase the parameters of the first unit to maintain rapid and continuous cooling. When the temperature drops to between 23°C and 26°C, the comfort level meets the user's needs. Maintain the parameters of the first unit. If the temperature drops further to 20°C, the room is too cold, resulting in over-cooling output. Reduce the parameters of the first unit to avoid further cooling.

[0102] 2. In heating mode, determine the temperature difference between the current ambient temperature and the set temperature; if the temperature difference remains below the third heating temperature threshold for a set period of time, control the second unit parameters to output with an increased amplitude, wherein the second unit parameters are used to increase the current ambient temperature; if the temperature difference remains within the preset temperature range for a set period of time, maintain the second unit parameters; if the temperature difference remains below the fourth heating temperature threshold for a set period of time, control the second unit parameters to output with a decreased amplitude, wherein the third heating temperature threshold is less than the value in the preset temperature range, and the value in the preset temperature range is less than the fourth heating temperature threshold.

[0103] For example, if the current ambient temperature is 20°C and the set temperature is 30°C, which is above the range of human comfort, and the current ambient temperature rises to 22°C, indoor comfort is still poor. Therefore, the parameters of the second unit are increased to maintain rapid and continuous heating. Once the temperature reaches between 23°C and 26°C, the comfort level meets the user's needs. The parameters of the second unit are then maintained. If the temperature is further increased to 28°C, the room becomes too hot, resulting in overheating. Therefore, the parameters of the second unit are reduced to prevent further heating.

[0104] In this application, each high-pressure or low-pressure correction, or unit parameter adjustment, will be identified and relevant control commands will be issued through the mobile communication system installed on the unit side. The system will automatically adjust the ambient temperature to meet the requirements in comfort mode and maintain operation within the temperature range, providing users with a more comfortable environment.

[0105] Energy-saving mode settings: While meeting basic user comfort requirements, settings are adjusted to make the unit operate more cost-effectively. Currently, cost-saving methods in the air conditioning industry fall into three categories: First, the unit side, mainly through control to ensure the unit operates in its high-efficiency range and in harmony with the environment, reducing energy waste; second, peak-valley electricity pricing, which is influenced by policy; and third, user behavior habits, adjusting controls based on user behavior habits to achieve energy savings. This solution primarily focuses on controlling from the perspective of user habits.

[0106] Energy-saving modes include the following two situations:

[0107] In the first scenario, the temperature difference between the current ambient temperature and the set temperature is determined. In cooling mode, if the temperature difference remains less than the minimum cooling difference, the low-pressure correction value is increased. Increasing the low-pressure correction value means raising the current saturation temperature of the refrigerant on the evaporator side. After detecting that the current ambient temperature has reached the set temperature, the increased low-pressure correction value is reset to zero.

[0108] For example, in cooling mode, if Δt≤2℃ is detected for 8 minutes, the target low pressure is increased by 1. After the current ambient temperature reaches the temperature point and the machine stops, the low pressure correction value is cleared.

[0109] In heating mode, if the temperature difference remains less than the minimum heating difference, the high-pressure correction value is reduced. This reduction refers to lowering the current refrigerant saturation temperature on the condenser side. Once the ambient temperature reaches the set temperature, the reduced high-pressure correction value is reset to zero.

[0110] In heating mode, if Δt≤-2℃ is detected for 8 minutes, the target high pressure is -1. After the current ambient temperature reaches the temperature point and the machine stops, the high pressure correction value is cleared.

[0111] Figure 5 This is a flowchart illustrating the energy-saving mode.

[0112] In the second scenario, a. if the user sets a shutdown time in the custom mode, then that shutdown time can be considered as the user having no need for air conditioning, and the energy-saving mode can also automatically shut down at that shutdown time.

[0113] b. If the user sets a fixed departure time in the custom mode, such as working hours from 9 am to 6 pm on weekdays, then it is assumed that the user has no need for air conditioning during this time period, and the energy-saving mode can also automatically shut down during this time period.

[0114] If both a and b are satisfied, then b takes precedence.

[0115] The server sends a shutdown command to the unit based on the time when there is no demand for air conditioning.

[0116] By automating the control of air conditioning operation through energy-saving modes, the unit can reduce its energy consumption to some extent.

[0117] The temperature difference mentioned above can be the difference between the current ambient temperature and the set temperature, or it can be the average of n current ambient temperatures collected at set intervals within a set time period.

[0118] In this solution, the air conditioning unit integrates with data analysis and artificial intelligence technologies to enable convenient operation based on scenarios and needs. This makes the air conditioning unit smarter, more user-aware, and provides more precise service to users. It eliminates the existing air conditioning control methods and opens up new control methods. At the same time, it can solve the problems of manual controllers being complicated, user-unfriendly, unintelligent, and failing to understand the actual needs of customers.

[0119] This application also provides a control device for an air conditioning unit, such as... Figure 6 As shown, the device includes:

[0120] The control module 601 is used to control the unit to enter the initialization mode after detecting that the unit is powered on, wherein the initialization mode includes cooling mode or heating mode.

[0121] The switching module 602 is used to switch to the control mode corresponding to a single button selected by the user during the initialization mode operation. The control mode includes comfort mode, energy-saving mode or custom mode. During the operation of comfort mode or energy-saving mode, the unit automatically adjusts the parameters.

[0122] Optionally, the device is also used for:

[0123] Get the user-set temperature in Comfort Mode;

[0124] Determine if the set temperature is within the range of human comfort.

[0125] If the parameters are within the range of human comfort, the unit parameters will be adjusted according to the first adjustment scheme.

[0126] If the parameters are not within the range of human comfort, the unit parameters will be adjusted according to the second adjustment scheme.

[0128] In cooling mode, determine the temperature difference between the current ambient temperature and the set temperature;

[0129] If the temperature difference remains greater than the first cooling temperature threshold within a set time period, the low-pressure correction value will be adjusted. Adjusting the low-pressure correction value means reducing the current evaporator-side refrigerant saturation temperature.

[0130] If the temperature difference remains between the second cooling temperature threshold and the first cooling temperature threshold within the set time period, the adjusted low pressure correction value will be maintained.

[0131] If the temperature difference remains below the second cooling temperature threshold for an extended period of time, the low-pressure correction value will be reset to zero.

[0132] Optionally, the device is also used for:

[0133] In heating mode, determine the temperature difference between the current ambient temperature and the set temperature;

[0134] If the temperature difference remains below the first heating temperature threshold for a set period of time, the high pressure correction value will be adjusted. Adjusting the high pressure correction value means increasing the current refrigerant saturation temperature on the condenser side.

[0135] If the temperature difference remains between the first heating temperature threshold and the second heating temperature threshold within the set time period, the adjusted high pressure correction value will be maintained.

[0136] If the temperature difference remains greater than the second heating temperature threshold for an extended period of time, the high-pressure correction value will be reset to zero.

[0137] Optionally, the device is also used for:

[0138] In cooling mode, determine the temperature difference between the current ambient temperature and the set temperature;

[0139] If the temperature difference remains greater than the third cooling temperature threshold for a set period of time, the first unit parameter is controlled to be output with an increased amplitude. The first unit parameter is used to reduce the current ambient temperature.

[0140] If the temperature difference remains within the preset temperature range for a set period of time, the parameters of the first unit will be maintained.

[0141] If the temperature difference remains below the fourth cooling temperature threshold for a set period of time, the parameters of the first unit will be controlled to be output with a reduced amplitude. The third cooling temperature threshold is greater than the value in the preset temperature range, and the value in the preset temperature range is greater than the fourth cooling temperature threshold.

[0142] Optionally, the device is also used for:
