Detailed Implementation

[0034] Embodiments of this disclosure are described in detail below, with examples of embodiments illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting this disclosure.

[0035] In related technologies, when multi-split air conditioners operate in cooling mode, the common methods for obtaining room temperature parameters include: Method 1: obtaining the air temperature of the area where the configured wired controller / smart screen / remote control is installed, and the control algorithm uses the wired controller temperature to represent the room temperature; Method 2: obtaining the air temperature at the return air vent of the air conditioner through a temperature sensor placed at the return air vent, and the control algorithm uses the return air temperature to represent the room temperature; Method 3: obtaining the air temperature at the location of a smart device through a linkage setting, and the control algorithm uses the smart device temperature to represent the room temperature. In cooling operation scenarios, the air temperature collected by multi-split air conditioners at the return air vent is generally higher than the average room temperature. The air temperature collected by the wired controller is limited by the installation location of the controller and may not necessarily represent the average room temperature. Furthermore, the temperature collected by smart devices can be changed at any time, resulting in uncertainty. Clearly, none of the methods used by multi-split air conditioners to obtain room temperature can cover the actual user's usage scenario, resulting in large temperature control deviations, affecting the user experience, and also leading to energy waste and increased financial expenditure for users.

[0036] Therefore, in order to solve the above-mentioned technical problems, this disclosure proposes a control method for air conditioning equipment, which improves room temperature control accuracy, enhances user experience, and optimizes air conditioning energy efficiency by fully considering the hardware conditions and usage scenarios of multi-split air conditioners.

[0037] The control method disclosed herein is applied to multi-split air conditioning systems. A multi-split air conditioning system is a centralized air conditioning system consisting of one or more outdoor units connected to multiple indoor units. Refrigerant serves as the heat transfer medium, circulating directly between the indoor and outdoor units. By controlling the refrigerant flow rate of the compressor and the heat exchange status of the indoor units, the real-time cooling / heating requirements of each indoor unit's area are precisely matched. Each indoor unit can be installed in a different room to independently adjust and correct the temperature of different room areas.

[0038] Specifically, the control method disclosed herein is executed by the main controller of the outdoor unit. Each indoor unit collects operating parameters in real time through its own sensors and control board. The main controller of the outdoor unit, as the main body for formulating temperature control strategies, periodically collects the control parameters and operating parameters of all indoor units through the communication network.

[0039] Furthermore, the outdoor unit can perform comprehensive calculations based on the control and operating parameters of each indoor unit using an operational control algorithm to determine the temperature control strategy for each indoor unit. Based on the temperature control strategies of all indoor units, system-level and device-level instructions are formulated. The system-level instructions determine the target operating frequency of the outdoor unit's inverter compressor, while the device-level instructions calculate the target opening degree of the electronic expansion valve for each indoor unit. The target opening degree thus corrects the operating temperature of each indoor unit.

[0040] Furthermore, each indoor unit receives device-level instructions and is executed by a local controller, which drives its own electronic expansion valve to precisely control the refrigerant flow into the unit.

[0041] For example, when the indoor unit's temperature control strategy is to lower the temperature, the device-level command can instruct the electronic expansion valve of the indoor unit to open wider, allowing more refrigerant liquid to flow into the evaporator of the indoor unit, enhancing the evaporation heat absorption capacity, resulting in a lower outlet air temperature and faster cooling.

[0042] For example, when the temperature in the area where the indoor unit is located is close to the set value, the device-level command can instruct the electronic expansion valve of the indoor unit to reduce the opening, limit the refrigerant flow, so that the cooling capacity is precisely matched with the current temperature, avoid overcooling, and achieve temperature stability.

[0043] The control method and apparatus for the air conditioning equipment proposed in this application will be described in detail below with reference to the accompanying drawings.

[0044] Figure 1 This is a flowchart of a method for controlling an air conditioning device according to an embodiment of the present disclosure, as shown below. Figure 1 As shown, the method includes the following steps.

[0045] Step 101: Determine the control parameters corresponding to the control mode of each indoor unit among the multiple indoor units of the air conditioning equipment.

[0046] In some embodiments, the control modes include custom modes and / or smart modes.

[0047] In some embodiments, each indoor unit can be individually controlled by the user, meaning that based on the user's selection, the control parameters of each indoor unit in the corresponding control mode can be determined separately.

[0048] In some embodiments, different control parameter sets can be configured for different control modes. Based on the user's specific selection among the options provided by the system in the selected control mode, the control parameters corresponding to the control mode of each indoor unit can be determined.

[0049] In some embodiments, the system provides selectable control modes for each indoor unit, which can be selected by the user using a control terminal such as a remote control or a display screen.

[0050] Specifically, the custom mode can be a mode that supports user-defined adjustment types. In custom mode, users can customize settings for different heating and cooling needs, and the system will run according to the parameters input by the user, providing predictable and stable environmental control.

[0051] Specifically, intelligent mode allows air conditioning equipment to automatically find and maintain the optimal comfort level based on sensor data and intelligent algorithms, while also saving energy. Intelligent mode is an adaptive mode based on artificial intelligence or advanced control algorithms. Users typically only need to activate the adjustment type in intelligent mode with one click, and the system will automatically determine the optimal parameters such as temperature and fan speed, without requiring users to manually set specific values.

[0052] In some embodiments, under different control modes, users can actively select different control types so that the main controller can determine the corresponding control parameters.

[0053] In some embodiments, the control parameters can be relevant calculation parameters used to generate temperature control strategies. For different control modes and different adjustment types, the corresponding control parameters are determined from the configured parameter set to achieve targeted determination of control parameters for different indoor unit control modes.

[0054] Step 102: During the operation of the air conditioning equipment in the control mode, obtain the air conditioning operating parameters, which include the operating parameters of each of the at least two indoor units.

[0055] In some embodiments, each indoor unit of the air conditioning equipment linkage control operates in the corresponding control mode. During operation, each indoor unit can send operating parameters to the main controller through a communication link, so that the main controller can apply the operating parameters of all indoor units to generate corresponding system-level instructions and device-level instructions.

[0056] In some embodiments, during the operation of the air conditioning equipment in the control mode, obtaining air conditioning operating parameters includes: obtaining operating parameters corresponding to the first indoor unit among at least two indoor units, the operating parameters including at least one of the set temperature, inner loop temperature, return air vent temperature, control terminal temperature, and linkage equipment temperature.

[0057] In some embodiments, the first indoor unit is any one of a plurality of indoor units controlled in conjunction with the air conditioning equipment.

[0058] In some embodiments, the air conditioning equipment can acquire the operating parameters of each indoor unit in real time, thereby using the operating parameters of all indoor units as the air conditioning operating parameters.

[0059] In some embodiments, the operating parameters of the indoor unit can be multiple temperatures corresponding to the indoor unit.

[0060] In some embodiments, the operating parameters may also include parameters such as exhaust, subcooling, actual noise level (via built-in or associated microphones), and swing angle, which are not limited in this disclosure.

[0061] In some embodiments, the air conditioning equipment outputs capacity based on user demand under the control mode.

[0062] In some embodiments, the inner ring temperature can be the core temperature of the area where the first indoor unit is located.

[0063] In some embodiments, the set temperature may be the desired temperature set by the user for the first indoor unit.

[0064] In some embodiments, the temperature of the control terminal can be the temperature of a device such as a wired controller, smart screen, or remote control. For example, it can be the temperature at the location of the wired controller.

[0065] In some embodiments, the temperature of the linked devices can be the temperature of at least one linked device associated with the first indoor unit. The linked device can be a smart device with temperature acquisition capabilities, which is bound to the first indoor unit. In other words, the first indoor unit can be bound to multiple linked devices.

[0066] In some embodiments, the temperature of the linkage device can be the ambient temperature around the linkage device, which is collected in real time by a sensor configured on the linkage device.

[0067] For example, if a user selects the "cooler" setting in the custom mode, the system will determine that a "rapid cooling" requirement is needed. The outdoor unit's inverter compressor will increase its frequency to operate at high load, all indoor unit fans will switch to their highest fan speed, and the electronic expansion valve will increase its opening to increase refrigerant flow. During this process, the operating parameters of each indoor unit will be collected in real time.

[0068] For example, the user selected the "Comfort" level custom mode, which aims to maintain a constant temperature with minimal noise. The outdoor unit compressor maintains low-frequency operation, all indoor unit fans are forced to the lowest fan speed or silent mode, and the inner ring temperature of each indoor unit and the temperature at the location of the wired controller are collected in real time.

[0069] For example, in the "linked intelligent type" intelligent mode, the air conditioning and fresh air system operate in conjunction. When the fresh air system introduces outdoor air, the air conditioning system dynamically adjusts its output capacity to compensate for the heat load brought by the fresh air. The system acquires the linked fresh air supply temperature and air volume signals, quantifying the impact of the linked equipment into parameters that can be understood by the air conditioning control system, providing a direct basis for dynamically correcting the air conditioning target temperature or output capacity.

[0070] In the above embodiments, multiple parameters, including the temperature of the inner loop, return air, wired controller, and linked equipment, are clearly collected, providing a multi-dimensional data foundation that is closer to the actual thermal environment state for subsequent control strategies, thereby improving the accuracy of state judgment and decision-making.

[0071] Step 103: Based on the control parameters corresponding to the control mode and the air conditioner operating parameters, determine the temperature control strategy to correct the operating temperature of each indoor unit of the air conditioning equipment.

[0072] In some embodiments, the main controller determines the temperature control strategy for each indoor unit based on the control parameters and operating parameters corresponding to the control mode of each indoor unit, and controls the controller of each indoor unit to execute the corresponding temperature control strategy through instructions, so as to correct the operating temperature of each indoor unit, thereby achieving coordinated control of the temperature correction of multiple indoor units.

[0073] In some embodiments, the main controller can generate a centralized temperature control strategy based on regulation parameters and air conditioning operating parameters, and each indoor unit can individually execute the corresponding temperature control strategy. Specifically, the outdoor unit's main controller calculates the opening command of the electronic expansion valve, and each indoor unit executes the command to achieve independent and precise control of its own room temperature by adjusting the refrigerant flow through it.

[0074] Furthermore, the outdoor compressor can adjust its operating frequency based on the temperature control strategies of all indoor units to match the total demand, thus forming a highly efficient, flexible, and precise core control closed loop for the multi-split air conditioning system. The specific implementation method of the outdoor compressor adjusting its operating frequency based on the temperature control strategies of all indoor units can adopt the decision-making method of current multi-split air conditioning systems, or it can adopt the specific implementation method of future multi-split air conditioning systems that generates total demand based on the needs of each indoor unit; this disclosure does not limit this approach.

[0075] In some embodiments, based on the control parameters and operating parameters corresponding to the control mode of each indoor unit, it is possible to determine whether the actual operating temperature in the current operating parameters has reached the temperature set by the user. If the temperature has not been reached, a temperature correction value is generated based on the control parameters. The temperature correction value is the main determining factor of the temperature control strategy, and the main controller generates the strategy for the opening degree of the electronic expansion valve of the indoor unit.

[0076] In some embodiments, the temperature control strategy for each indoor unit based on the control parameters and operating parameters can be formulated using a pre-trained temperature control model, which is trained using historical temperature control data.

[0077] Specifically, the training method for the temperature control model is not limited in this disclosure. The temperature control model can be trained using historical temperature control data in the cloud and deployed in the main controller of the air conditioning equipment, or it can be trained within the main controller of the air conditioning equipment. The temperature control model can use a neural network model to learn the mapping relationship of historical temperature control data. Based on forward and backward propagation, the parameters of each network layer in the neural network model are gradually adjusted through a set loss function and optimizer. The temperature control model is obtained when the number of iterations or the loss function is minimized.

[0078] In some embodiments, the neural network model may be a concatenated convolutional neural network-recurrent neural network (CNN-RNN), a Transformer model, a CNN-Transformer model, a graph neural network (GNN) model, a multilayer perceptron (MLP), etc., and this disclosure does not limit it.

[0079] Furthermore, any future neural network model can be used to train the temperature control model.

[0080] In some embodiments, the optimizer is, for example, any one of Adam, AdaGrad, RMSProp, etc., which is not limited in this disclosure.

[0081] In some embodiments, the temperature control strategy for each indoor unit can be formulated based on the control parameters and operating parameters by using a lookup table generated from historical control data to generate the temperature control strategy.

[0082] For example, such as Figure 8A The schematic diagram shows that in a multi-split air conditioner temperature control device, the temperature control input module and the control mode module acquire the control mode set by the user, the data acquisition module acquires the corresponding operating parameters, completes the calculation, and delivers them to the temperature control execution module to output specific control instructions. The control mode module allows users to set the specific operating control mode of the air conditioner; the data acquisition module acquires / calculates the operating parameters of the air conditioner and the operating parameters of the intelligent devices linked to the air conditioner for control; the temperature control execution module, based on the operating control parameters set by the user in the control mode module and the air conditioner operating parameters acquired by the data acquisition module, formulates specific control strategies according to the temperature control model and outputs them to the air conditioner's control center.

[0083] In some embodiments, if the user selects a custom mode and a smart mode for the first indoor unit, the temperature control strategy is determined to be a first temperature control strategy of the adjustment type corresponding to the custom mode and a second temperature control strategy of the adjustment type corresponding to the smart mode. In other words, the main controller generates a first device-level instruction based on the first temperature control strategy and a second device-level instruction based on the second temperature control strategy. These instructions are then sent to the execution module of the first indoor unit, which performs a temperature correction process based on the two device-level instructions.

[0084] In the above embodiments, a unified control framework of user-defined custom mode and intelligent mode is used to dynamically generate temperature control strategies based on the overall control mode and the operating data of multiple indoor units, thereby optimizing the overall temperature control accuracy and energy efficiency of the multi-split system while meeting personalized needs.

[0085] Figure 2 This is a schematic flowchart illustrating another control method for an air conditioning device proposed in an embodiment of this disclosure. Based on Figure 1 The embodiment shown, Figure 2 Step 101 is further defined, such as... Figure 2 As shown, the method includes the following steps.

[0086] Step 201: In response to the triggering operation of the custom mode, determine the adjustment type corresponding to the custom mode.

[0087] In some embodiments, the adjustment type is any one of warmer, slightly warmer, comfortable, slightly colder, and cooler, and the parameter of the adjustment type includes a first correction value corresponding to the first state and a range of second correction values ​​corresponding to the second state.

[0088] In some embodiments, in response to a user selecting a custom mode, the system provides multiple adjustment types for the user to choose from. The user makes the selection via a control terminal such as a remote control or a display screen. The main controller, in response to the user's selection command, determines the corresponding adjustment type in the custom mode.

[0089] In some embodiments, the system provides two states for each adjustment type for the user to choose from, and the value or range of the correction value provided by the system may be different in different states.

[0090] In some embodiments, the first state can be a default state, and the second state can be a custom state. In the first state, the system provides a default first correction value, and in the second state, the system provides a custom range of correction values, i.e., a second correction value range, within which the user can select a specific second correction value.

[0091] For example, for a warmer adjustment type, the first correction value in the first state is T. 设定修正_偏暖_默认 The range of the second correction value in the second state is T. 设定修正_偏暖_自定义 For example, the second correction value ranges from 2℃ to 3℃, with a minimum accuracy of 0.1℃, meaning it can take values ​​of 2.1℃, 2.2℃, ..., 2.9℃, and 3.0℃. Users can select from this range, causing the main controller to respond to the user's selection and determine the second correction value.

[0092] For example, for a slightly warmer adjustment type, the first correction value in the first state is T. 设定修正_稍暖_默认 The range of the second correction value in the second state is T. 设定修正_稍暖_自定义 For example, the second correction value ranges from 0.8℃ to 1.9℃, with a minimum accuracy of 0.1℃. Therefore, possible values ​​are 0.8℃, 0.9℃, ..., 1.8℃, and 1.9℃. Users can select from this range, causing the main controller to determine the second correction value in response to the user's selection.

[0093] For example, for the comfort adjustment type, the first correction value in the first state is T. 设定修正_舒适_默认 The range of the second correction value in the second state is T. 设定修正_舒适_自定义 For example, the second correction value ranges from -0.5℃ to 0.5℃, with a minimum accuracy of 0.1℃. Examples of possible values ​​are -0.5℃, -0.4℃, ..., 0.4℃, and 0.5℃. Users can select from this range, causing the main controller to determine the second correction value in response to the user's selection.

[0094] For example, for a slightly colder adjustment type, the first correction value in the first state is T. 设定修正_稍冷_默认The range of the second correction value in the second state is T. 设定修正_稍冷_自定义 For example, the second correction value ranges from -0.8℃ to -1.9℃, with a minimum accuracy of 0.1℃. Therefore, possible values ​​are -0.8℃, -0.9℃, ..., -1.8℃, and -1.9℃. Users can select from this range, causing the main controller to determine the second correction value in response to the user's selection.

[0095] For example, for a cooling-type adjustment, the first correction value in the first state is T. 设定修正_偏冷_默认 The range of the second correction value in the second state is T. 设定修正_偏冷_自定义 For example, the second correction value ranges from -2℃ to -3℃, with a minimum accuracy of 0.1℃, meaning possible values ​​are -2.0℃, -2.1℃, ..., -2.9℃, and -3.0℃. Users can select from this range, causing the main controller to determine the second correction value in response to the user's selection.

[0096] Step 202: In response to the user's parameter selection instruction, determine the correction temperature and temperature adjustment amount corresponding to the adjustment type in the parameters of the adjustment type.

[0097] In some embodiments, the control parameters include at least one of the correction temperature and the temperature adjustment amount.

[0098] In some embodiments, in response to a user's parameter selection instruction, determining the correction temperature corresponding to the adjustment type from the parameters of the adjustment type includes any one of the following: in response to a user's parameter selection instruction, determining a first correction value corresponding to a first state as the correction temperature; in response to a user's parameter selection instruction, determining a second correction value within the range of second correction values ​​corresponding to a second state, and determining the second correction value as the correction temperature.

[0099] In some embodiments, in response to a user's parameter selection instruction, a first correction value can be determined in a first state selected by the user, or a second correction value can be determined in a second state.

[0100] For example, when a user sets the temperature control parameter to "warmer" and selects the default setting, the default T... 设定修正_偏暖_默认 The temperature was set at 2℃.

[0101] For example, when a user sets the temperature control parameter to "warmer" and selects a custom setting, the system provides multiple T... 设定修正_偏暖_自定义 The value is available for the user to select, with a specific range of 2℃ to 3℃. The user selects a specific value, such as T. 设定修正_偏暖_自定义 The temperature was set at 2.2℃.

[0102] Specifically, for adjustment types such as slightly warm, comfortable, slightly cool, and slightly cold, the temperature correction value can be determined within the range of the first correction value of the first state or the second correction value of the second state corresponding to the adjustment type, based on the user's selection. The specific implementation method is the same as the example of the slightly warm type, and will not be repeated here.

[0103] In some embodiments, the temperature adjustment amount is the step size for successive corrections in a pre-defined temperature control strategy for each type of regulation.

[0104] In some embodiments, the temperature adjustment amount of different adjustment types may be the same or different, and can be customized according to the scenario or needs. This disclosure does not limit this.

[0105] Specifically, for the adjustment type of warm, the temperature adjustment amount can be 0.2℃; for the adjustment type of slightly warm, the temperature adjustment amount can be 0.1℃; for the adjustment type of comfortable, the temperature adjustment amount can be 0.1℃; for the adjustment type of cool, the temperature adjustment amount can be -0.2℃; and for the adjustment type of slightly cool, the temperature adjustment amount can be -0.1℃.

[0106] In the above embodiments, two determination methods are provided: "directly adopting the preset correction value" and "selecting within the preset range". This balances the convenience and precision of control, meeting the user's need for quick setting and providing more personalized fine-tuning space for advanced users.

[0107] In the above embodiments, by refining the custom mode into multiple adjustment types from "warmer" to "cooler", and presetting different correction parameters for each type, users can express their body preferences in an intuitive and hierarchical manner. At the same time, it provides the system with a structured basis for parameter adjustment, thereby improving the flexibility and user-friendliness of the control.

[0108] Figure 3 This is a schematic flowchart illustrating another control method for an air conditioning device proposed in an embodiment of this disclosure. Based on Figures 1-2 The embodiment shown, Figure 3 right Figure 1 Step 101 further defines the terms, such as... Figure 3 As shown, it includes the following steps.

[0109] Step 301: In response to the triggering operation of the smart mode, determine the adjustment type corresponding to the smart mode.

[0110] In some embodiments, the adjustment type is either a standard intelligent type or a linkage intelligent type.

[0111] In some embodiments, when a user selects the intelligent mode, the system provides the user with two adjustment types to choose from. The user can select the adjustment type corresponding to the intelligent mode through a control terminal such as a remote control or a display screen.

[0112] In some embodiments, the standard intelligent type means that the air conditioning device performs intelligent control based solely on its own operating parameters, while the linked intelligent type means that the air conditioning device requires intelligent control based on the operating parameters of at least one linked device. In other words, if the user selects the linked intelligent type, the corresponding indoor unit is associated with at least one linked device, and the temperature detected by the sensors of each linked device can be used as the linked device temperature for intelligent control of that indoor unit.

[0113] For example, users can set specific air conditioning temperature control parameters according to their personal preferences or actual experience when the air conditioning unit is in standby or running state, and set the air conditioning temperature control mode to smart mode; the smart mode provides users with two smart modes, specifically including: standard smart mode and linkage smart mode.

[0114] Furthermore, in the standard intelligent mode, the control mode module obtains the return air temperature of the air conditioner and the temperature parameters of the wired controller, processes them through an algorithm, and outputs specific temperature adjustment parameters as control parameters.

[0115] Furthermore, in the intelligent linkage mode, the control mode module requires users to bind a smart device with temperature acquisition capabilities to the air conditioner. The control mode module obtains the return air temperature of the air conditioner and the temperature parameters of the linked device, processes them through an algorithm, and outputs specific temperature adjustment parameters.

[0116] Step 302: Determine the first parameter set and the second parameter set corresponding to the adjustment type.

[0117] In some embodiments, the control parameters include a first set of parameters and a second set of parameters.

[0118] In some embodiments, the first parameter set and the second parameter set may be a set of value ranges for the first and second parameters used to calculate the temperature regulation parameters in intelligent mode.

[0119] For example, the first set of parameters can be the set of values ​​for α, the second set of parameters can be the set of values ​​for β, and α and β can be calculated parameters used to generate temperature control parameters in intelligent mode.

[0120] Specifically, the system can set different sets of first and second parameters for the return air temperature. For example, when the return air temperature is greater than or equal to 30℃, the first and second parameter sets can include the value ranges of α and β under different operating parameter conditions. For example, in the first case, α... 1.1 The preferred value range for β is: 0.60 ~ 0.70. 1.1 The preferred value range is 0.75 ~ 0.85; in the second case, α 1.2 The preferred value range for β is 0.55 ~ 0.65. 1.2 The preferred value range is 0.80 ~ 0.90; in the third case, α 1.3 The preferred value range for β is 0.50 ~ 0.60. 1.3 The preferred value range is 0.85 ~ 0.95; in the fourth case, α 1.4 The preferred value range for β is 0.45 ~ 0.55. 1.4 The preferred value range is 0.90 ~ 1.00.

[0121] Specifically, when the return air temperature is less than 30℃ and greater than or equal to 25℃, the first parameter set and the second parameter set can include the range of values ​​for α and β under different operating parameter conditions. For example, in the first case, α 2.1 The preferred value range for β is: 0.90 ~ 1.00. 2.1 The preferred value range is 0.10 ~ 0.20; in the second case, α 2.2 The preferred value range for β is 0.80 ~ 0.90. 2.2 The preferred value range is 0.20 ~ 0.30; in the third case, α 2.3 The preferred value range for β is 0.70 ~ 0.80. 2.3 The preferred value range is 0.30 ~ 0.40; in the fourth case, α 2.4 The preferred value range is: 0.65 ~ 0.75, β 2.4 The preferred value range is 0.40 ~ 0.50.

[0122] Specifically, when the return air temperature is less than 25℃, the first parameter set and the second parameter set can include the value ranges of α and β under different operating parameter conditions. For example, in the first and second cases, the first and second parameters do not need to be configured; in the third case, α... 3.1 The preferred value range is: 0.85 ~ 0.95, β 3.1 The preferred value range is 0.10~0.20; in the fourth case, α 3.2The preferred value range for β is: 0.75 ~ 0.85. 3.2 The preferred value range is 0.25 ~ 0.35.

[0123] In the above embodiments, by distinguishing between two types, "standard intelligence" and "linked intelligence," and presetting corresponding parameter sets, the intelligent control can adapt to different application scenarios (such as conventional room control and linkage control with fresh air / underfloor heating equipment), thereby enhancing the system's adaptability to complex environments.

[0124] Figure 4 This is a schematic flowchart illustrating another control method for an air conditioning device proposed in an embodiment of this disclosure. Based on Figures 1-3 The embodiment shown, Figure 4 right Figure 1 Step 101 further defines the terms, such as... Figure 4 As shown, it includes the following steps.

[0125] Step 401: In response to the triggering operations of custom mode and smart mode, determine the adjustment type corresponding to custom mode and the adjustment type corresponding to smart mode.

[0126] In some embodiments, in response to a user selecting a custom mode and an intelligent mode via a control terminal, the system provides the user with a corresponding adjustment type for each adjustment mode. The user selects the mode via the control terminal, and the main controller determines the adjustment type corresponding to the custom mode and the adjustment type corresponding to the intelligent mode, respectively.

[0127] In some embodiments, after the user selects a custom mode and a smart mode, the main controller needs to generate a temperature control strategy for the custom mode and a temperature control strategy for the smart mode. The indoor unit needs to execute the temperature control strategies corresponding to the two modes simultaneously.

[0128] In some embodiments, the specific implementation of determining the adjustment type corresponding to the custom mode can be found in [reference needed]. Figure 2 The optional implementation methods of step 201 will not be elaborated here.

[0129] In some embodiments, the specific implementation of determining the adjustment type corresponding to the intelligent mode can be found in [reference needed]. Figure 3 The optional implementation methods of step 301 will not be elaborated here.

[0130] Specifically, when both custom mode and smart mode are enabled, the system provides users with two specific control modes: custom + standard smart mode and custom + linked smart mode.

[0131] For example, when a user simultaneously activates both custom mode and smart mode, the control mode module implements the control logic of smart mode while also taking into account the user's custom temperature control needs.

[0132] Step 402: Determine the control parameters for the control type corresponding to the custom mode and the control parameters for the control type corresponding to the smart mode.

[0133] In some embodiments, the master controller determines the control parameters corresponding to the control type of the custom mode based on the control type selected by the user. For details on the implementation, please refer to [link / reference needed]. Figure 2 The specific implementation method of step 202 will not be described here.

[0134] In some embodiments, the master controller determines the control parameters corresponding to the intelligent mode based on the adjustment type selected by the user. For details on the implementation, please refer to [link to relevant documentation]. Figure 3 The specific implementation of step 302 will not be elaborated here.

[0135] In the above embodiments, it is supported that the custom mode and the intelligent mode are triggered simultaneously and the parameters are determined separately, realizing the integration of user subjective preferences and system objective intelligent adjustment, laying the foundation for the generation of composite control strategies, and improving the overall performance of the system under different operating conditions.

[0136] Figure 5 This is a schematic flowchart illustrating another control method for an air conditioning device proposed in an embodiment of this disclosure. Based on Figures 1-4 The embodiment shown, Figure 5 right Figure 1 Step 103 in the text is further defined, such as Figure 5 As shown, it includes the following steps.

[0137] Step 501: In response to the trigger operation of the custom mode, determine the operating status of the first indoor unit based on the first operating parameters of the first indoor unit in the air conditioner operating parameters.

[0138] In some embodiments, when the user selects a custom mode, it is first necessary to determine the current operating status of the first indoor unit based on the first operating parameters of the first indoor unit, so as to generate logic for adopting corresponding temperature control strategies based on different operating statuses.

[0139] In some embodiments, the operating state of the first indoor unit is determined based on the first operating parameter of the first indoor unit in the air conditioning operating parameters, including any one of the following: when the difference between the inner ring temperature and the set temperature is greater than or equal to a first value and less than or equal to a second value, the operating state of the first indoor unit is determined to be a stable state; when the difference between the inner ring temperature and the set temperature is less than the first value or greater than the second value, the operating state of the first indoor unit is determined to be an unstable state.

[0140] In some embodiments, the current operating status of the first indoor unit can be determined based on the first operating parameters of the first indoor unit. This can be done by comparing the difference between the inner ring temperature and the set temperature with a preset judgment threshold to determine the operating status of the first indoor unit.

[0141] In some embodiments, the first value and the second value can be preset temperature values, and their specific values ​​can be customized according to the scenario or requirements.

[0142] For example, the first value is -1.0℃, and the second value is 1.0℃.

[0143] In some embodiments, a stable state may be characterized by a small difference between the current inner ring temperature of the first indoor unit and the set temperature set by the user, i.e., the first indoor unit is operating in the temperature control stage; an unstable state may be characterized by a large difference between the current inner ring temperature of the first indoor unit and the set temperature set by the user, i.e., the first indoor unit is operating in the temperature control stage before reaching the temperature.

[0144] Specifically, the generation logic of the temperature control strategy can be different in stable and unstable states. The main controller adopts the corresponding generation logic to generate the temperature control strategy for different states.

[0145] For example, during the temperature control stage, the specific technical specifications are: -1.0℃≤T 内环 –T 设定 ≤1.0℃; Temperature control stage not reached. Specific technical specifications are: T 内环 –T 设定 >1.0℃ or T 内环 –T 设定 <-1.0℃.

[0146] In the above embodiments, a clear and quantifiable stable state determination criterion based on the difference range between the inner ring temperature and the set temperature is provided, which makes the control logic deterministic and repeatable, and provides clear triggering conditions for the subsequent implementation of differentiated control strategies.

[0147] Step 502: Based on the operating status of the first indoor unit and the control parameters corresponding to the custom mode, determine the first temperature control strategy of the first indoor unit under the control type corresponding to the custom mode.

[0148] In some embodiments, the generation logic of the first temperature control strategy is determined based on the operating state of the first indoor unit, and the corresponding generation logic is used to determine the first temperature control strategy based on the control parameters.

[0149] Option 1: The operating state is stable.

[0150] In some embodiments, based on the operating state of the first indoor unit and the control parameters corresponding to the custom mode, a first temperature control strategy for the first indoor unit under the control type corresponding to the custom mode is determined, including: in response to the first indoor unit's operating state being a stable state, determining a preset control cycle corresponding to the control type; determining the number of corrections based on the correction temperature and temperature adjustment amount in the control parameters corresponding to the control type; and determining the first temperature control strategy as increasing or decreasing the temperature adjustment amount sequentially according to the preset control cycle and with the number of corrections as the number of executions.

[0151] In some embodiments, in response to the first indoor unit being in a stable operating state, a preset control cycle corresponding to the adjustment type is determined. This can be done by first determining the preset control cycle of the stable state in the stable state.

[0152] In some embodiments, the preset control period is a pre-set correction period for temperature control strategies in a stable state, and its specific value can be customized according to the scenario or requirements.

[0153] Specifically, different preset control cycles can be set for different types of adjustment.

[0154] For example, the preset adjustment cycle is 2 minutes for the warm setting; 1.5 minutes for the slightly warm setting; 2 minutes for the comfortable setting; 2.5 minutes for the cool setting; and 2 minutes for the slightly cool setting.

[0155] In some embodiments, the number of corrections is determined based on the correction temperature and temperature adjustment amount in the control parameters corresponding to the control type. The number of corrections can be determined by the ratio of the absolute values ​​of the correction temperature and the temperature adjustment amount.

[0156] Specifically, the adjustment type is set to warmer, and the number of corrections can be T. 设定修正_偏暖 / 0.2℃; Adjustment type is slightly warmer, correction number can be T 设定修正_稍暖 / 0.1℃; Adjustment type is comfort, correction times can be T. 设定修正_舒适 / 0.1℃; the adjustment type is set to slightly cool, and the correction count can be T. 设定修正_偏冷 / 0.2℃; Adjustment type is slightly cooler, correction number can be T 设定修正_稍冷 / 0.1℃.

[0157] In some embodiments, the first temperature control strategy is determined to increase or decrease the temperature adjustment amount successively according to a preset control cycle and with the number of corrections as the number of executions. This can be achieved by generating a first temperature control strategy based on a preset control cycle, the number of corrections, and the temperature adjustment amount for different control types under different operating conditions.

[0158] Specifically, the adjustment type is either warmer, slightly warmer, or comfortable. The first temperature control strategy is to follow a preset control cycle, with the number of corrections as the number of executions, and to gradually increase the temperature adjustment amount based on the set temperature.

[0159] Specifically, the adjustment type is slightly cooler or cooler. The first temperature control strategy is to follow the preset control cycle, with the number of corrections as the number of executions, and to gradually reduce the temperature adjustment amount based on the set temperature.

[0160] For example, when the air conditioner is in the temperature control stage, if the control mode module receives a user-selected custom mode and sets it to one of the control parameters of "warmer", "slightly warmer", or "comfortable", the following control strategy is executed, and the control effect is as follows: Figure 8B As shown: When the control parameter is set to "warmer", T 设定_修正 = T 设定_初始 + [0.2℃ / 2min]^(T 设定修正_偏暖 / 0.2℃); When the control parameter is set to "slightly warm", T 设定_修正 = T 设定_初始 + [0.1℃ / 1.5min]^(T 设定修正_稍暖 / 0.1℃); when the control parameter is set to "comfort", T 设定_修正 = T 设定_初始 + [0.1℃ / 2min]^(T 设定修正_舒适 / 0.1℃).

[0161] Among them, T 设定_初始 The definition refers to the initial target indoor ambient temperature set by the user on the air conditioner via a wired controller / central control screen / remote control, used to regulate room temperature; the unit is ℃; T. 设定_修正 The interpretation of "0.2℃ / 2min" is that after the control mode module processes the corresponding correction logic according to the control parameters, it is used to adjust the corrected set temperature for room temperature, in °C; the interpretation of "0.2℃ / 2min" is that when the control parameter is set to "warmer", the control mode module adjusts every 2 minutes, at T 设定_初始 Increase the temperature correction by 0.2℃ based on the existing value; ^(T 设定修正_偏暖 The interpretation of " / 0.2℃" refers to the number of temperature corrections the control mode module needs to perform when the control parameter is set to "warm". Specifically, the control mode module operates on a 2-minute control cycle, with T... 设定_初始 Based on this, an increase of 0.2℃ in temperature correction is required, and the total number of executions is (T). 设定修正_偏暖 / 0.2℃); 【0.1℃ / 1.5min】 means that when the control parameter is set to "slightly warm", the control mode module adjusts every 1.5 minutes, at T 设定_初始Increase the temperature correction by 0.1℃ based on the existing temperature range; ^(T 设定修正_稍暖 The interpretation of " / 0.1℃" refers to the number of temperature corrections the control mode module needs to perform when the control parameter is set to "slightly warm". Specifically, the control mode module operates on a 1.5-minute control cycle, with T... 设定_初始 To increase the temperature correction by 0.1℃ based on the existing parameters, the total number of executions required is (T). 设定修正_稍暖 / 0.1℃); 【0.1℃ / 2min】 means that when the control parameter is set to "comfort", the control mode module adjusts every 2 minutes, at T 设定_初始 Increase / decrease the temperature correction by 0.1℃ based on the existing temperature range; ^(T 设定修正_舒适 The interpretation of " / 0.1℃" is that when the control parameter is set to "comfort", the control mode module needs to perform temperature corrections a certain number of times. Specifically, the control mode module operates on a 2-minute control cycle, and the temperature correction is performed at T... 设定_初始 Based on the above, increasing / decreasing the temperature correction by 0.1℃, the total number of times this operation needs to be performed is (T). 设定修正_舒适 / 0.1℃).

[0162] For example, when the air conditioner is in the temperature control stage, if the control mode module receives a user-selected custom mode and sets it to one of the control parameters "too cool" or "slightly cool", the following control strategy is executed, and the control effect is as follows: Figure 8D As shown: When the control parameter is set to "cool", T 设定_修正 = T 设定_初始 - [0.2℃ / 2.5min]^(T 设定修正_偏冷 / 0.2℃); When the control parameter is set to "slightly cool", T 设定_修正 = T 设定_初始 - [0.1℃ / 2min]^(T 设定修正_稍冷 / 0.1℃). The interpretation of 【0.2℃ / 2.5min】 is that when the control parameter is set to "slightly cool", the control mode module adjusts every 2.5 minutes, at T 设定_初始 The temperature correction is reduced by 0.2℃ from the base temperature; ^(T 设定修正_偏冷 The interpretation of " / 0.2℃" is that when the control parameter is set to "slightly cold", the control mode module needs to perform temperature corrections several times. Specifically, the control mode module operates on a 2.5-minute control cycle, with T... 设定_初始 Based on this, a temperature correction of 0.2℃ is reduced. The total number of executions required is (T...). 设定修正_偏冷 The interpretation of 【0.1℃ / 2min】 is that when the control parameter is set to "slightly cool", the control mode module adjusts every 2 minutes, at T设定_初始 The temperature correction is reduced by 0.1℃ from the base temperature; ^(T 设定修正_稍冷 The interpretation of " / 0.1℃" is that when the control parameter is set to "slightly cool", the control mode module needs to perform temperature corrections a certain number of times. Specifically, the control mode module operates on a 2-minute control cycle, with T... 设定_初始 Based on this, a temperature correction of 0.1℃ is reduced. The total number of executions required is (T...). 设定修正_稍冷 / 0.1℃).

[0163] In the above embodiments, after the system stabilizes, a fixed cycle, fixed adjustment amount, and gradual adjustment method is adopted to smoothly and accurately correct the indoor temperature to the user's preferred temperature, avoiding sudden temperature changes and significantly improving comfort.

[0164] Option 2: The operating state is unstable.

[0165] In some embodiments, based on the operating state of the first indoor unit and the control parameters corresponding to the custom mode, a first temperature control strategy for the first indoor unit under the control type corresponding to the custom mode is determined, including: in response to the first indoor unit's operating state being unstable, determining a preset control cycle corresponding to the control type; determining a first coefficient corresponding to the control type based on the difference between the inner loop temperature and the set temperature; determining the number of corrections based on the correction temperature and temperature adjustment amount in the control parameters corresponding to the control type, and the first coefficient; and determining the first temperature control strategy as follows: according to the preset control cycle, with the number of corrections as the execution number, the first adjustment amount is successively increased or decreased, where the first adjustment amount is the calculated value of the temperature adjustment amount and the first coefficient.

[0166] In some embodiments, in response to the first indoor unit being in an unstable operating state, determining the preset control cycle corresponding to the adjustment type can be done by first determining the preset control cycle corresponding to the adjustment type in the unstable state.

[0167] In some embodiments, the preset control period is a pre-set correction period for temperature control strategies in unstable states, and its specific value can be customized according to the scenario or requirements.

[0168] Specifically, different preset control cycles can be set for different types of adjustment.

[0169] Specifically, the preset control cycles for the same control type can be the same or different for stable and unstable states.

[0170] For example, the preset adjustment cycle is 1 minute for the warmer setting; 2 minutes for the slightly warmer setting; 3 minutes for the comfortable setting; 1 minute for the cooler setting; and 2 minutes for the slightly cooler setting.

[0171] In some embodiments, the first coefficient corresponding to the adjustment type is determined based on the difference between the inner ring temperature and the set temperature. This can be achieved by pre-setting the value of the first coefficient under different difference conditions, so that the value of the first coefficient is determined based on the real-time difference between the inner ring temperature and the set temperature.

[0172] In some embodiments, the adjustment type is warmer. When the difference between the inner ring temperature and the set temperature is greater than the first preset value, the value range of the first coefficient is [0.9, 1.1]; when the difference between the inner ring temperature and the set temperature is greater than the second preset value and less than or equal to the first preset value, the value range of the first coefficient is [1.2, 1.4]; when the difference between the inner ring temperature and the set temperature is less than or equal to the second preset value, the value range of the first coefficient is [1.4, 1.8].

[0173] Specifically, the first preset value can be 3℃, and the second preset value can be 1℃. The first coefficient is, for example, δ1.

[0174] In some embodiments, the adjustment type is slightly warm. When the difference between the inner ring temperature and the set temperature is greater than the first preset value, the value range of the first coefficient is [0.8, 0.9]; when the difference between the inner ring temperature and the set temperature is greater than the second preset value and less than or equal to the first preset value, the value range of the first coefficient is [1.0, 1.1]; when the difference between the inner ring temperature and the set temperature is less than or equal to the second preset value, the value range of the first coefficient is [1.2, 1.3].

[0175] Specifically, the first preset value can be 3℃, and the second preset value can be 1℃. The first coefficient is, for example, δ2.

[0176] In some embodiments, the adjustment type is comfort. When the difference between the inner ring temperature and the set temperature is greater than a first preset value, the value range of the first coefficient is [0.7, 0.8]; when the difference between the inner ring temperature and the set temperature is greater than a second preset value and less than or equal to the first preset value, the value range of the first coefficient is [0.9, 1.0]; when the difference between the inner ring temperature and the set temperature is less than or equal to the second preset value, the value range of the first coefficient is [1.1, 1.2].

[0177] Specifically, the first preset value can be 3℃, and the second preset value can be 1℃. The first coefficient is, for example, δ3.

[0178] In some embodiments, the adjustment type is cooling. When the difference between the inner ring temperature and the set temperature is greater than a first preset value, the value range of the first coefficient is [1.0, 1.2]; when the difference between the inner ring temperature and the set temperature is greater than a second preset value and less than or equal to the first preset value, the value range of the first coefficient is [1.2, 1.6]; when the difference between the inner ring temperature and the set temperature is less than or equal to the second preset value, the value range of the first coefficient is [1.6, 2.0].

[0179] Specifically, the first preset value can be 3℃, and the second preset value can be 1℃. The first coefficient is, for example, δ4.

[0180] In some embodiments, the adjustment type is slightly cooler. When the difference between the inner ring temperature and the set temperature is greater than the first preset value, the value range of the first coefficient is [0.9, 1.0]; when the difference between the inner ring temperature and the set temperature is greater than the second preset value and less than or equal to the first preset value, the value range of the first coefficient is [1.0, 1.2]; when the difference between the inner ring temperature and the set temperature is less than or equal to the second preset value, the value range of the first coefficient is [1.3, 1.5].

[0181] Specifically, the first preset value can be 3℃, and the second preset value can be 1℃. The first coefficient is, for example, δ5.

[0182] In some embodiments, the number of corrections is determined based on the correction temperature and temperature adjustment amount in the control parameters corresponding to the control type, as well as the first coefficient. This can be achieved by multiplying the temperature adjustment amount and the first coefficient as the denominator and the correction temperature as the numerator, and then performing a division operation to obtain the number of corrections.

[0183] For example, the adjustment type is warmer, and the number of corrections is T. 设定修正_偏暖 / 0.2℃*δ1; Adjustment type is slightly warmer, correction number is T 设定修正_稍暖 / 0.1℃*δ2; Adjustment type is comfort, correction times are T 设定修正_舒适 / 0.1℃*δ3; Adjustment type is slightly cool, correction times are T 设定修正_偏冷 / 0.2℃*δ4; Adjustment type is slightly cool, correction times are T 设定修正_稍冷 / 0.1℃*δ5.

[0184] In some embodiments, the first temperature control strategy is determined to be to increase or decrease the first adjustment amount successively according to a preset control cycle, with the number of corrections as the number of executions, wherein the first adjustment amount is the calculated value of the temperature adjustment amount and the first coefficient.

[0185] Specifically, the first adjustment amount is the product of the temperature adjustment amount and the first coefficient.

[0186] Specifically, when the control parameter is set to "warmer", T 设定_修正 = T 设定_初始 + [0.2℃*δ1 / 1min]^(T 设定修正_偏暖 / 0.2℃*δ1); When the control parameter is set to "slightly warm", T 设定_修正 = T 设定_初始 + [0.1℃*δ2 / 2min]^(T 设定修正_稍暖 / 0.1℃*δ2); When the control parameter is set to "comfort", T 设定_修正 = T 设定_初始 + [0.1℃*δ3 / 3min]^(T 设定修正_舒适 / 0.1℃*δ3). Where, when T 内环 - T 设定_初始 When the temperature is greater than 3℃, the preferred value range for δ1 is 0.9 ~ 1.1, the preferred value range for δ2 is 0.8 ~ 0.9, and the preferred value range for δ3 is 0.7 ~ 0.8; when the temperature is less than 1℃, the preferred value range for δ3 is 0.9 ~ 1.1. 内环 -T 设定_初始 ≤ 3℃, the preferred value range for δ1 is 1.2 ~ 1.4, the preferred value range for δ2 is 1.0 ~ 1.1, and the preferred value range for δ3 is 0.9 ~ 1.0; when T 内环 -T 设定_初始 <1℃, the preferred value range for δ1 is 1.4 ~ 1.8, the preferred value range for δ2 is 1.2 ~ 1.3, and the preferred value range for δ3 is 1.1 ~ 1.2.

[0187] Specifically, when the control parameter is set to "slightly cool", T 设定_修正 = T 设定_初始 + [0.2℃*δ4 / 1min]^(T 设定修正_偏冷 / 0.2℃*δ4); When the control parameter is set to "slightly cool", T 设定_修正 = T 设定_初始 +【0.1℃*δ5 / 2min】^(T 设定修正_稍冷 / 0.1℃*δ5). Wherein, when T 内环 - T 设定_初始 When the temperature is greater than 3℃, the preferred value range for δ4 is 1.0 ~ 1.2, and the preferred value range for δ5 is 0.9 ~ 1.0; when 1℃ < T 内环 -T 设定_初始 ≤ 3℃, the preferred value range for δ4 is 1.2 ~ 1.6, and the preferred value range for δ5 is 1.0 ~ 1.2; when T 内环 -T 设定_初始 <1℃, the preferred value range for δ4 is 1.6 ~ 2.0, and the preferred value range for δ5 is 1.3 ~ 1.5.

[0188] In some embodiments, the first temperature control strategy is defined as increasing or decreasing the first adjustment amount successively according to a preset control cycle and with the number of corrections as the number of executions. This can be achieved by generating a first temperature control strategy based on a preset control cycle, the number of corrections, and the first adjustment amount for different control types under different operating conditions.

[0189] Specifically, the adjustment type is either warmer, slightly warmer, or comfortable. The first temperature control strategy is to follow a preset control cycle, with the number of corrections as the number of executions, and to gradually increase the first adjustment amount based on the set temperature.

[0190] Specifically, the adjustment type is slightly cooler or cooler. The first temperature control strategy is to follow a preset control cycle, with the number of corrections as the number of executions, and to gradually reduce the first adjustment amount based on the set temperature.

[0191] In the above embodiments, when the system is unstable, a first coefficient based on the temperature difference is introduced to dynamically adjust the correction amount each time, so that the control intensity is proportional to the current temperature deviation, thereby making more active intervention in the rapid temperature adjustment phase, accelerating the system to reach the stable range, and improving the adjustment efficiency.

[0192] In the above embodiments, by first determining whether the indoor unit is operating stably, the control strategy of the custom mode is dynamically associated with the actual operating status of the equipment, avoiding improper intervention when the system is not yet stable, and ensuring the effectiveness of the control action and the smooth operation of the system.

[0193] Figure 6 This is a schematic flowchart illustrating another control method for an air conditioning device proposed in an embodiment of this disclosure. Based on Figures 1-5 The embodiment shown, Figure 6 right Figure 1 Step 103 in the text is further defined, such as Figure 6 As shown, it includes the following steps.

[0194] Step 601: In response to the adjustment type of the smart mode being the standard smart type, a first parameter is determined from the first set of adjustment parameters and a second parameter is determined from the second set of adjustment parameters based on the return air temperature of the first indoor unit and the temperature of the control terminal.

[0195] In some embodiments, when the user selects the standard smart type in smart mode, the main controller determines a first parameter from a first parameter set and a second parameter from a second parameter set based on the different conditions of the return air temperature of the first indoor unit and the temperature of the control terminal.

[0196] In some embodiments, the main controller can adaptively select the first parameter set and the second parameter set based on the real-time temperature, which correspond to different ranges of the difference between the preset return air temperature and the control terminal temperature.

[0197] The following explanation uses a wired controller as the control terminal.

[0198] Specifically, when T 回风 When ≥ 30℃: If T 回风 -T 线控器 When the temperature is ≥5℃, determine the first parameter α. 1.1 Second parameter β 1.1 If 3℃≤T 回风 -T 线控器 When <5℃, determine the first parameter α. 1.2 Second parameter β 1.2 If 1℃≤T 回风 -T 线控器 <3℃, determine the first parameter α 1.3 Second parameter β 1.3 If T 回风 -T 线控器 <1℃, determine the first parameter α 1.4 Second parameter β 1.4 α 1.1 The preferred value range is: 0.60 ~ 0.70; α 1.2 The preferred value range is: 0.55 ~ 0.65; α 1.3 The preferred value range is: 0.50 ~ 0.60; α 1.4 The preferred value range is: 0.45 ~ 0.55; β 1.1 The preferred value range is: 0.75 ~ 0.85; β 1.2 The preferred value range is: 0.80 ~ 0.90; β 1.3 The preferred value range is: 0.85 ~ 0.95; β 1.4 The preferred value range is 0.90 ~ 1.00.

[0199] Specifically, when 25℃ ≤ T 回风 When < 30℃: Determine the first parameter α 2.1 Second parameter β 2.1 If 3℃≤T 回风 -T 线控器 <5℃, determine the first parameter α 2.2 Second parameter β 2.2 If 1℃≤T 回风 -T 线控器 <3℃, determine the first parameter α 2.3Second parameter β 2.3 If T 回风 -T 线控器 <1℃, determine the first parameter α 2.4 Second parameter β 2.4 Where α 2.1 The preferred value range is: 0.90 ~ 1.00; α 2.2 The preferred value range is: 0.80 ~ 0.90; α 2.3 The preferred value range is: 0.70 ~ 0.80; α 2.4 The preferred value range is: 0.65 ~ 0.75; β 2.1 The preferred value range is: 0.10 ~ 0.20; β 2.2 The preferred value range is: 0.20 ~ 0.30; β 2.3 The preferred value range is: 0.30 ~ 0.40; β 2.4 The preferred value range is 0.40 ~ 0.50.

[0200] Specifically, when T 回风 When < 25℃: If 1℃ ≤ T 回风 -T 线控器 <3℃, determine the first parameter α 3.1 Second parameter β 3.1 If T 回风 -T 线控器 <1℃, determine the first parameter α 3.2 Second parameter β 3.2 Where α 3.1 The preferred value range is: 0.85 ~ 0.95; α 3.2 The preferred value range is: 0.75 ~ 0.85; β 3.1 The preferred value range is: 0.10 ~ 0.20; β 3.2 The preferred value range is 0.25 ~ 0.35.

[0201] Step 602: Determine the target inner loop temperature based on at least two of the return air temperature, control terminal temperature, set temperature, first parameter, and second parameter.

[0202] In some embodiments, the target inner loop temperature is determined based on at least two of the return air temperature, control terminal temperature, set temperature, first parameter, and second parameter. This can be achieved by calculating the target inner loop temperature using the following formula when the return air temperature is greater than or equal to 25°C: Target inner loop temperature = return air temperature - [first parameter × (return air temperature + control terminal temperature) - set temperature] × second parameter.

[0203] In some embodiments, the target inner ring temperature can be calculated using the following formula when the return air temperature is less than 25°C: Return air temperature - control terminal temperature ≥ 5℃, target inner loop temperature = return air temperature - 0.5℃.

[0204] 3℃≤Return air temperature - control terminal temperature<5℃, target inner loop temperature=Return air temperature-1.5℃.

[0205] 1℃≤Return air temperature - control terminal temperature<3℃, target inner loop temperature = return air temperature - [first parameter × (return air temperature + control terminal temperature) - set temperature] × second parameter.

[0206] Return air temperature - control terminal temperature < 1℃, target inner loop temperature = return air temperature - [first parameter × (return air temperature + control terminal temperature) - set temperature] × second parameter.

[0207] Step 603: Determine the second temperature control strategy under the standard intelligent type corresponding to the intelligent mode as adjusting the inner ring temperature of the first indoor unit to the target inner ring temperature.

[0208] In some embodiments, the second temperature control strategy under the standard intelligent type can be to set the target value of the inner ring temperature of the first indoor unit to the target inner ring temperature calculated in step 603. During the process of the first indoor unit performing temperature control based on the second temperature control strategy, the inner ring temperature can be raised or lowered to the target inner ring temperature by adjusting the opening of the solenoid valve.

[0209] In the above embodiments, the target inner loop temperature is calculated by combining the return air temperature, the wired controller temperature, and preset intelligent parameters. This allows the control target to comprehensively consider the actual temperature of the space and the temperature set by the user, intelligently eliminating the difference between the two and achieving more uniform temperature control that better matches the user's actual experience.

[0210] Figure 7 This is a schematic flowchart illustrating another control method for an air conditioning device proposed in an embodiment of this disclosure. Based on Figures 1-6 The embodiment shown, Figure 7 right Figure 1 Step 103 in the text is further defined, such as Figure 7 As shown, it includes the following steps.

[0211] Step 701: In response to the intelligent mode adjustment type being the linkage intelligent type, based on the return air temperature of the first indoor unit and the temperature of the linkage equipment, a first parameter is determined from the first parameter set of the control parameters, and a second parameter is determined from the second parameter set of the control parameters.

[0212] In some embodiments, when the first indoor unit is bound to one linkage device, the temperature of the linkage device can be the temperature collected by the linkage device; when the first indoor unit is bound to at least two linkage devices, the temperature of the linkage device can be the average of the temperatures collected by at least two linkage devices.

[0213] In some embodiments, when the user selects the smart linkage type, the specific implementation of determining the first parameter and the second parameter based on the return air temperature of the first indoor unit and the temperature of the linked equipment is as follows: Specifically, when T 回风 When ≥ 30℃: If T 回风 -T 联动 When the temperature is ≥5℃, determine the first parameter α. 1.1 Second parameter β 1.1 If 3℃≤T 回风 - T 联动 When <5℃, determine the first parameter α. 1.2 Second parameter β 1.2 If 1℃≤T 回风 - T 联动 <3℃, determine the first parameter α 1.3 Second parameter β 1.3 If T 回风 - T 联动 <1℃, determine the first parameter α 1.4 Second parameter β 1.4 α 1.1 The preferred value range is: 0.60 ~ 0.70; α 1.2 The preferred value range is: 0.55 ~ 0.65; α 1.3 The preferred value range is: 0.50 ~ 0.60; α 1.4 The preferred value range is: 0.45 ~ 0.55; β 1.1 The preferred value range is: 0.75 ~ 0.85; β 1.2 The preferred value range is: 0.80 ~ 0.90; β 1.3 The preferred value range is: 0.85 ~ 0.95; β 1.4 The preferred value range is 0.90 ~ 1.00.

[0214] Specifically, when 25℃ ≤ T 回风 When < 30℃: Determine the first parameter α 2.1 Second parameter β 2.1 If 3℃≤T 回风 - T 联动 <5℃, determine the first parameter α 2.2 Second parameter β 2.2 If 1℃≤T回风 - T 联动 <3℃, determine the first parameter α 2.3 Second parameter β 2.3 If T 回风 - T 联动 <1℃, determine the first parameter α 2.4 Second parameter β 2.4 Where α 2.1 The preferred value range is: 0.90 ~ 1.00; α 2.2 The preferred value range is: 0.80 ~ 0.90; α 2.3 The preferred value range is: 0.70 ~ 0.80; α 2.4 The preferred value range is: 0.65 ~ 0.75; β 2.1 The preferred value range is: 0.10 ~ 0.20; β 2.2 The preferred value range is: 0.20 ~ 0.30; β 2.3 The preferred value range is: 0.30 ~ 0.40; β 2.4 The preferred value range is 0.40 ~ 0.50.

[0215] Specifically, when T 回风 When < 25℃: If 1℃ ≤ T 回风 - T 联动 <3℃, determine the first parameter α 3.1 Second parameter β 3.1 If T 回风 - T 联动 <1℃, determine the first parameter α 3.2 Second parameter β 3.2 Where α 3.1 The preferred value range is: 0.85 ~ 0.95; α 3.2 The preferred value range is: 0.75 ~ 0.85; β 3.1 The preferred value range is: 0.10 ~ 0.20; β 3.2 The preferred value range is 0.25 ~ 0.35.

[0216] Step 702: Determine the linkage correction temperature based on the return air temperature and the temperature of the linked equipment.

[0217] In some embodiments, determining the linkage correction temperature based on the return air temperature and the linked device temperature includes: in response to the return air temperature being greater than or equal to a preset temperature, determining the linkage temperature drop rate based on the linkage temperature of at least one linked device associated with the first indoor unit at a historical time and the linkage temperature at the current time; and determining the linkage correction temperature based on the linkage temperature drop rate.

[0218] In some embodiments, the preset temperature may be a predetermined method for determining the linkage correction temperature by judging the return air temperature.

[0219] For example, the preset temperature is 25℃.

[0220] Specifically, when the return air temperature is greater than or equal to 25°C, the linkage correction temperature is determined based on the preset range of linkage correction temperature and the linkage temperature drop rate.

[0221] In some embodiments, the linkage temperature drop rate can be the rate of temperature change of at least one linkage device within a preset sampling time.

[0222] Specifically, when the first indoor unit is bound to a linked device, the linkage temperature drop rate can be the rate of change between the linkage temperature at a historical moment and the linkage temperature at the current moment.

[0223] For example, it could be the change between the temperature value collected by the linked device 3 minutes ago and the temperature value collected at the current moment.

[0224] For example, when the air conditioner is only paired with one linked device capable of collecting temperature data: T 联动温降速率 = (T) 联动_(t-3min) - T 联动_(t) ) / 3; where T 联动_(t-3min) This indicates the controlled temperature values ​​collected by the linkage device in the first 3 minutes, in °C (°C); T. 联动_(t) This indicates the air temperature value collected by the linkage device at the current moment, in °C.

[0225] For example, when the air conditioner is only linked to multiple interconnected devices capable of collecting temperature data: T 联动温降速率 = Ave(T) 联动_(t-3min)_i - T 联动_(t)_i ) / 3; where, T 联动_(t-3min)_i This indicates the air temperature value collected by the linkage device numbered i in the previous 3 minutes, in °C (°C); T. 联动_(t-3min)_i This indicates the air temperature value collected at the current moment by the linkage device numbered i, in °C; Ave (T 联动_(t-3min)_i - T 联动_(t)_i This represents the total average temperature change over the past 3 minutes for all linked devices connected to the air conditioner that have the ability to collect temperature data.

[0226] In some embodiments, the linkage correction temperature is determined based on the linkage temperature drop rate. This can be based on a pre-defined correspondence between the linkage temperature drop rate and the linkage correction temperature, or on the calculated linkage temperature drop rate.

[0227] Specifically, T 联动温降速率 ≥ 1.0℃ / min, T 联动修正_1 The preferred value range is: 1.0℃ ~ 1.5℃; 0.5℃ / min ≤T 联动温降速率 < 1.0℃ / min, T 联动修正_1 The preferred value range is: 0.8℃ ~ 1.2℃; T 联动温降速率 < 0.5℃ / min, T 联动修正_1 The preferred value range is 0.3℃ ~ 0.8℃.

[0228] In the above embodiments, the temperature drop rate is calculated by analyzing the historical and current temperatures of the linked equipment, and the target temperature is predicted and corrected accordingly. This enables the control system to have a certain learning and predictive ability, allowing it to respond to environmental changes in advance and improving the anticipation and stability of the control.

[0229] In some embodiments, determining the linkage correction temperature based on the return air temperature and the linked equipment temperature includes: determining a second coefficient and a third coefficient in response to the return air temperature being lower than a preset temperature; and determining the linkage correction temperature based on the return air temperature, the linked equipment temperature, the second coefficient, and the third coefficient.

[0230] In some embodiments, the preset temperature may be a predetermined method for determining the linkage correction temperature by judging the return air temperature.

[0231] For example, the preset temperature is 25℃.

[0232] Specifically, when the return air temperature is less than 25°C, the linkage correction temperature is calculated based on the determined second and third coefficients, combined with the return air temperature and the temperature of the linked equipment.

[0233] In some embodiments, when the return air temperature is less than a preset temperature, the second coefficient can be λ and the third coefficient can be μ. The second and third coefficients can be pre-set calculation parameters when the return air temperature is less than 25°C.

[0234] Specifically, the preferred value range for the second coefficient is 0.35 to 0.65, and the preferred value range for the second coefficient is -0.20 to -0.45.

[0235] In some embodiments, the linkage correction temperature is determined based on the return air temperature, the temperature of the linked equipment, the second coefficient, and the third coefficient. The linkage correction temperature can be calculated using the following formula: T 联动修正_3 =λ×( T 回风 -T 联动)+ μ, where the temperature of the linkage device can be the temperature collected by the linkage device when there is only one linkage device, or the average value of the temperatures collected by all linkage devices when there are multiple linkage devices.

[0236] In the above embodiments, under specific conditions (such as low return air temperature), second and third coefficients are introduced to calculate the linkage correction temperature, providing compensation logic under special operating conditions and enhancing the robustness and adaptability of linkage intelligent control under complex or extreme conditions.

[0237] Step 703: Determine the target inner loop temperature based on at least two of the following: return air temperature, linkage equipment temperature, set temperature, linkage correction temperature, first parameter, and second parameter.

[0238] In some embodiments, the target inner loop temperature is determined based on at least two of the return air temperature, the linkage equipment temperature, the set temperature, the linkage correction temperature, the first parameter, and the second parameter. This can be achieved by judging the difference between the return air temperature and the linkage equipment temperature, and using the first parameter and the second parameter determined in step 701 to calculate the target inner loop temperature based on the set temperature, the linkage correction temperature, the return air temperature, and the linkage equipment temperature.

[0239] Specifically, when T 回风 When ≥ 30℃: If T 回风 -T 联动 When the temperature is ≥5℃, use the corresponding first and second parameters and the linked correction temperature for calculation; if 3℃ ≤ T 回风 - T 联动 When <5℃, use the corresponding α 1.2 and β 1.2 And the linkage correction temperature calculation; if 1℃≤ T 回风 - T 联动 <3℃, use the corresponding α 1.3 and β 1.3 And linkage correction temperature calculation; if T 回风 -T 联动 <1℃, use the corresponding α 1.4 and β 1.4 And the linkage correction temperature calculation.

[0240] Specifically, when 25℃ ≤ T 回风 When < 30℃: Determine the first parameter α 2.1 Second parameter β 2.1 If 3℃≤T 回风 - T 联动 <5℃, use the corresponding α 2.2 Second parameter β 2.2 Calculations are performed using the linked correction temperature; if 1℃ ≤ T回风 -T 联动 <3℃, use the corresponding α 2.3 and β 2.3 Calculate the temperature and its correlation correction; if T 回风 - T 联动 <1℃, use the corresponding α 2.4 and β 2.4 Calculations are performed using the linkage correction temperature.

[0241] In the above cases, the calculation formula is as follows: Target inner loop temperature = return air temperature - [first parameter × (return air temperature + linked equipment temperature) - set temperature] × second parameter + linked correction temperature.

[0242] Specifically, when T 回风 When < 25℃: If 1℃ ≤ T 回风 - T 联动 <3℃, use the corresponding α 3.1 and β 3.1 Calculate the temperature and its correlation correction; if T 回风 - T 联动 <1℃, use the corresponding α 3.2 and β 3.2 The calculation is performed in conjunction with the linkage correction temperature. The calculation formula is as follows: Target inner loop temperature = return air temperature - [first parameter × (return air temperature + linked equipment temperature) - set temperature] × second parameter + linked correction temperature.

[0243] Specifically, when T 回风 When < 25℃: If T 回风 -T 联动 ≥5℃, target inner ring temperature = return air temperature - 0.5℃ + linkage correction temperature; if 3℃ ≤ T 回风 -T 联动 <5℃, target inner ring temperature = return air temperature - 1.5℃ + linkage correction temperature.

[0244] Step 704: Determine the second temperature control strategy under the linkage intelligent type corresponding to the intelligent mode as adjusting the inner ring temperature of the first indoor unit to the target inner ring temperature.

[0245] In some embodiments, by calculating the target inner ring temperature under the linkage intelligent type corresponding to the intelligent mode, the second temperature control strategy is determined to set the target value of the current inner ring temperature of the first indoor unit as the target inner ring temperature.

[0246] Specifically, the main controller will generate device-level instructions for the first indoor unit based on the second temperature control strategy, and the first indoor unit will then perform temperature correction with the target inner loop temperature as the target based on the instructions.

[0247] In the above embodiments, by introducing the temperature of linked devices (such as humidifiers and sensors) and calculating the linked correction temperature, the air conditioning equipment can sense and respond to changes in related environmental factors, realizing intelligent environmental regulation through cross-device collaboration, and improving the overall comfort and consistency of the environment.

[0248] In summary, the air conditioning equipment control method proposed in this disclosure can generate corresponding temperature control strategies for each indoor unit based on its control mode and operating parameters.

[0249] Specifically, when the user selects the custom mode for the first indoor unit, a first temperature control strategy corresponding to the adjustment type in the custom mode is generated. The main controller generates a first device-level instruction for the first temperature control strategy and sends it to the first indoor unit to perform temperature correction.

[0250] Specifically, when the user selects the smart mode for the first indoor unit, a second temperature control strategy corresponding to the adjustment type in the smart mode is generated. The main controller generates a second device-level instruction for the second temperature control strategy and sends it to the first indoor unit to perform temperature correction.

[0251] Specifically, when the user selects a custom mode + smart mode for the first indoor unit, a first temperature control strategy corresponding to the adjustment type in the custom mode and a second temperature control strategy corresponding to the adjustment type in the smart mode are generated. The main controller generates a first device-level instruction for the first temperature control strategy and a second device-level instruction for the second temperature control strategy, and sends them to the first indoor unit to perform temperature correction.

[0252] For example, when a user selects the custom + smart mode, the control mode module implements the control logic of the smart mode while also taking into account the user's custom temperature control needs. The smart mode provides the user with two smart modes, specifically: custom + standard smart mode and custom + linkage smart mode.

[0253] (1) Custom + Standard Intelligent Mode: When the user sets the custom + standard intelligent mode, the control mode module sends the T to the temperature control execution module. 自定义+标准智能 According to the following control model: T 自定义+标准智能 = T 自定义 + T 标准智能 In the formula, T 自定义 The value is determined based on the air conditioning temperature control parameters set by the user in the custom module, such as T. 设定_暖 T 设定_稍暖 T 设定_舒适 T 设定_稍冷 T 设定_偏冷 The specific parameters.

[0254] (2) Custom + Linkage Intelligent Mode: When the user sets the custom + linkage intelligent mode, the control mode module sends the T to the temperature control execution module. 自定义+联动智能 According to the following control model: T 自定义+联动智能 = T 自定义 + T 联动智能 In the formula, T 自定义 The value is determined based on the air conditioning temperature control parameters set by the user in the custom module, such as T. 设定_暖 T 设定_稍暖 T 设定_舒适 T 设定_稍冷 T 设定_偏冷 The specific parameters.

[0255] In summary, the air conditioning equipment control method proposed in this disclosure, through user-defined control modes and real-time collection of actual operating parameters of multiple indoor units of the air conditioning equipment, adaptively determines the temperature control strategy of each indoor unit to achieve coordinated temperature correction of multiple indoor units, thereby improving the adaptability and accuracy of temperature control.

[0256] The following are specific implementation methods for temperature control in multi-split air conditioning systems: Figure 8A This is a framework diagram of the application scenarios of this solution, such as... Figure 8A As shown, under the joint control of the temperature control input module and the temperature control execution module, the operating parameters of the air conditioning unit are obtained, and a specific temperature control strategy is formulated according to the temperature control mode selected by the user. The specific temperature control strategy is then output by the temperature control execution module.

[0257] The temperature control input module is used to: activate the control mode module to obtain the user-set control mode, then the data acquisition module acquires the corresponding operating parameters, completes the calculation, and delivers the specific control instructions to the temperature control execution module; the control mode module is used to: provide users with the option to set the specific operating mode of the air conditioner; the data acquisition module is used to: acquire / calculate the operating parameters of the air conditioner and the operating parameters of intelligent devices linked to the air conditioner, such as, but not limited to: T 内环 T 设定 T 回风 T 线控器 T 联动 T 排气 T 过冷度 Operating parameters; the temperature control execution module is used to: formulate specific control strategies based on the operating control parameters set by the user in the control mode module and the air conditioner operating parameters obtained by the data acquisition module, and output them to the air conditioner control center.

[0258] 1.

[0274] Second: Users can set specific air conditioning temperature control parameters according to their personal preferences or actual experience in the standby and running states of the air conditioning unit. The specific implementation method is as follows.

[0275] 1. Temperature control scenario 1.

[0276] Temperature control scenario 1: When the air conditioner is in the temperature control phase, if the control mode module receives a user-selected custom mode and sets it to one of the control parameters of "warmer", "slightly warmer", or "comfortable", the following control strategy will be executed, and the control effect will be as follows: Figure 8B As shown.

[0277] When the control parameter is set to "warmer", T 设定_修正 = T 设定_初始 + [0.2℃ / 2min]^(T 设定修正_偏暖 / 0.2℃).

[0278] When the control parameter is set to "slightly warm", T 设定_修正 = T 设定_初始 + [0.1℃ / 1.5min]^(T 设定修正_稍暖 / 0.1℃).

[0279] When the control parameter is set to "comfort", T 设定_修正 = T 设定_初始 + [0.1℃ / 2min]^(T 设定修正_舒适 / 0.1℃).

[0280] Specifically, during the temperature control phase, the specific technical specifications are: -1.0℃ ≤T 内环 – T 设定 ≤ 1.0℃.

[0281] Temperature control has not yet been achieved; specific technical specifications are as follows: T 内环 – T 设定 > 1.0℃ or T 内环 – T 设定 < -1.0℃.

[0282] T 设定_初始 This refers to the initial target indoor ambient temperature set by the user on the air conditioner via a wired controller / central control screen / remote control for room temperature regulation, measured in °C; T. 设定_修正This refers to the corrected set temperature used to regulate room temperature after the control mode module processes the control parameters according to the corresponding correction logic. The unit is ℃.

[0283] 【0.2℃ / 2min】 means that when the control parameter is set to "warmer", the control mode module adjusts every 2 minutes, at T 设定_初始 Increase the temperature correction by 0.2℃ based on the existing value; ^(T 设定修正_偏暖 / 0.2℃) refers to the number of temperature corrections the control mode module needs to perform when the control parameter is set to "warm". That is, the control mode module operates on a 2-minute control cycle, with T... 设定_初始 Based on this, an increase of 0.2℃ in temperature correction is required, and the total number of executions is (T). 设定修正_偏暖 / 0.2℃).

[0284] 【0.1℃ / 1.5min】 means that when the control parameter is set to "slightly warm", the control mode module adjusts every 1.5 minutes, at T 设定_初始 Increase the temperature correction by 0.1℃ based on the existing temperature range; ^(T 设定修正_稍暖 / 0.1℃) refers to the number of temperature corrections the control mode module needs to perform when the control parameter is set to "slightly warm".

[0285] 【0.1℃ / 2min】 means that when the control parameter is set to "comfort", the control mode module adjusts every 2 minutes, at T 设定_初始 Increase / decrease the temperature correction by 0.1℃ based on the existing temperature range; ^(T 设定修正_舒适 / 0.1℃) refers to the number of temperature corrections the control mode module needs to perform when the control parameter is set to "comfort". That is, the control mode module operates on a 2-minute control cycle, with T... 设定_初始 Based on the above, increasing / decreasing the temperature correction by 0.1℃, the total number of times this operation needs to be performed is (T). 设定修正_舒适 / 0.1℃).

[0286] 2. Temperature control scenario 2.

[0288] When the control parameter is set to "warmer", T 设定_修正 = T 设定_初始 + [0.2℃*δ1 / 1min]^(T 设定修正_偏暖 / 0.2℃*δ1).

[0289] When the control parameter is set to "slightly warm", T 设定_修正 = T 设定_初始 + [0.1℃*δ2 / 2min]^(T 设定修正_稍暖 / 0.1℃*δ2).

[0290] When the control parameter is set to "comfort", T 设定_修正 = T 设定_初始 + [0.1℃*δ3 / 3min]^(T 设定修正_舒适 / 0.1℃*δ3).

[0294] When the control parameter is set to "slightly cool", T 设定_修正 = T 设定_初始 - [0.2℃ / 2.5min]^(T 设定修正_偏冷 / 0.2℃).

[0295] When the control parameter is set to "slightly cool", T 设定_修正 = T 设定_初始 - [0.1℃ / 2min]^(T 设定修正_稍冷 / 0.1℃).

[0296] Specifically, 【0.2℃ / 2.5min】 means that when the control parameter is set to "slightly cool", the control mode module adjusts every 2.5 minutes, at T 设定_初始 The temperature correction is reduced by 0.2℃ from the base temperature; ^(T 设定修正_偏冷 / 0.2℃) refers to the number of temperature corrections the control mode module needs to perform when the control parameter is set to "slightly cool". That is, the control mode module operates on a 2.5-minute control cycle, with T... 设定_初始 Based on this, a temperature correction of 0.2℃ is reduced. The total number of executions required is (T...). 设定修正_偏冷 / 0.2℃).

[0297] 【0.1℃ / 2min】 means that when the control parameter is set to "slightly cool", the control mode module adjusts every 2 minutes, at T 设定_初始 The temperature correction is reduced by 0.1℃ from the base temperature; ^(T 设定修正_稍冷 / 0.1℃) refers to the number of temperature corrections the control mode module needs to perform when the control parameter is set to "slightly cool". That is, the control mode module operates on a 2-minute control cycle, with T... 设定_初始 Based on this, a temperature correction of 0.1℃ is reduced. The total number of executions required is (T...). 设定修正_稍冷 / 0.1℃).

[0298] 4. Temperature control scenario 4.

[0299] Temperature control scenario 4: When the air conditioner is in the temperature control stage before reaching the set temperature, if the control mode module receives a user-selected custom mode and sets it to one of the control parameters "too cool" or "slightly cool", the following control strategy will be executed, and the control effect will be as follows: Figure 8E As shown.

[0300] When the control parameter is set to "slightly cool", T 设定_修正 = T 设定_初始 + [0.2℃*δ4 / 1min]^(T 设定修正_偏冷 / 0.2℃*δ4).

[0301] When the control parameter is set to "slightly cool", T 设定_修正 = T 设定_初始 +【0.1℃*δ5 / 2min】^(T 设定修正_稍冷 / 0.1℃*δ5).

[0302] In particular, when T 内环 - T 设定_初始When the temperature is greater than 3℃, the preferred value range for δ4 is 1.0 ~ 1.2, and the preferred value range for δ5 is 0.9 ~ 1.0; when 1℃ < T 内环 -T 设定_初始 ≤ 3℃, the preferred value range for δ4 is 1.2 ~ 1.6, and the preferred value range for δ5 is 1.0 ~ 1.2; when T 内环 -T 设定_初始 <1℃, the preferred value range for δ4 is 1.6 ~ 2.0, and the preferred value range for δ5 is 1.3 ~ 1.5.

[0304] Specifically, users can set specific air conditioning temperature control parameters according to their personal preferences or actual experience when the air conditioning unit is in standby or running state, and set the air conditioning temperature control mode to smart mode.

[0305] The intelligent mode offers users two modes: standard intelligent mode and interconnected intelligent mode.

[0306] 1. Standard Intelligent Mode: In this mode, the control mode module obtains the return air temperature of the air conditioner and the temperature parameters of the wired controller, processes them through an algorithm, and outputs specific temperature adjustment parameters.

[0307] When the user selects to enable the standard smart mode, the specific control logic of the control mode module is as follows: When T 回风 When ≥ 30℃: If T 回风 -T 线控器 At ≥5℃, T 目标内环_标准智能 = T 回风 –

[0308] In particular, T 目标内环_标准智能 This refers to the target ambient temperature control value in the room under the execution standard intelligent mode, sent by the control mode module to the temperature control execution module. The unit is °C; T. 回风 This refers to the air temperature detected by the temperature sensor at the return air vent of the indoor unit of the air conditioner, in degrees Celsius (°C); t. 线控器 This refers to the air temperature detected by the central control screen, wired controller, remote control, etc. of the air conditioner, in °C.

[0310] When 25℃ ≤ T 回风 When < 30℃: If T 回风 -T 线控器 At ≥5℃, T 目标内环_标准智能 = T 回风 –

α 2.1 *(T 回风 +T 线控器 )- T 设定

α 2.2 *(T 回风 +T 线控器 )-T 设定

α 2.3 *(T 回风 +T 线控器 )- T 设定

α 2.4 *(T 回风 +T 线控器 )- T 设定

[0311] In particular, α 2.1 The preferred value range is: 0.90 ~ 1.00; α 2.2 The preferred value range is: 0.80 ~ 0.90; α 2.3 The preferred value range is: 0.70 ~ 0.80; α 2.4 The preferred value range is: 0.65 ~ 0.75; β 2.1 The preferred value range is: 0.10 ~ 0.20; β 2.2 The preferred value range is: 0.20 ~ 0.30; β 2.3 The preferred value range is: 0.30 ~ 0.40; β 2.4 The preferred value range is 0.40 ~ 0.50.

[0312] When T 回风 When < 25℃: If T 回风 -T 线控器 ≥5℃, T 目标内环_标准智能 = T 回风 - 0.5℃; if 3℃≤T 回风 -T 线控器 <5℃, T 目标内环_标准智能 = T 回风 – 1.5℃; if 1℃ ≤ T 回风 -T 线控器 <3℃, T 目标内环_标准智能 = T 回风 –

[0313] In particular, α 3.1 The preferred value range is: 0.85 ~ 0.95; α 3.2 The preferred value range is: 0.75 ~ 0.85; β 3.1 The preferred value range is: 0.10 ~ 0.20; β 3.2 The preferred value range is 0.25 ~ 0.35.

[0314] 2. Intelligent Linkage Mode: In this mode, the control mode module requires users to bind a smart device with temperature acquisition capabilities to the air conditioner. The control mode module obtains the return air temperature of the air conditioner and the temperature parameters of the linked device, processes them through an algorithm, and outputs specific temperature adjustment parameters.

[0315] Specifically, when a user selects the smart linkage mode, at least one smart device with temperature acquisition capabilities must be bound to the air conditioner, and multiple smart devices with temperature acquisition capabilities can be bound to the air conditioner.

[0316] When a user selects to enable the intelligent linkage mode, the specific control logic of the control mode module is as follows: When T 回风 When ≥ 30℃: If T 回风 -T 联动 ≥5℃, T 目标内环_联动智能 = T 回风 –

[0317] In particular, T 目标内环_联动智能 This refers to the target ambient temperature control value in the room under the intelligent linkage mode, sent from the control mode module to the temperature control execution module. The unit is °C; T. 联动温降速率 ≥ 1.0℃ / min, T 联动修正_1 The preferred value range is: 1.0℃ ~ 1.5℃; 0.5℃ / min ≤T 联动温降速率 < 1.0℃ / min, T 联动修正_1 The preferred value range is: 0.8℃~1.2℃; T 联动温降速率 < 0.5℃ / min, T 联动修正_1 The preferred value range is: 0.3℃ ~ 0.8℃; T 联动温降速率 The interpretation is that the rate of temperature change detected by the linkage device in the past 3 minutes is calculated as follows.

[0318] (1) When the air conditioner is only bound to one linkage device with temperature acquisition capability: T 联动温降速率 = (T) 联动_(t-3min) - T 联动_(t) ) / 3.

[0319] (2) When the air conditioner is only linked to multiple interconnected devices capable of collecting temperature data: T 联动温降速率 = Ave(T) 联动_(t-3min)_i - T 联动_(t)_i ) / 3.

[0320] In the formula, T 联动_(t-3min) This indicates the controlled temperature values ​​collected by the linkage device in the first 3 minutes, in °C (°C); T. 联动_(t) This indicates the current air temperature value collected by the linkage device, in degrees Celsius (°C); t. 联动_(t-3min)_i This indicates the air temperature value collected by the linkage device numbered i in the previous 3 minutes, in °C (°C); T. 联动_(t-3min)_iThis indicates the air temperature value collected at the current moment by the linkage device numbered i, in °C; Ave (T 联动_(t-3min)_i - T 联动_(t)_i This represents the total average temperature change over the past 3 minutes for all linked devices connected to the air conditioner that have the ability to collect temperature data.

[0321] When 25℃ ≤T 回风 When <30℃: If T 回风 -T 联动 ≥5℃, T 目标内环_联动智能 = T 回风 –

α 2.1 *(T 回风 +T 联动 )- T 设定

α 2.1 *(T 回风 +T 联动 )-T 设定

α 2.2 *(T 回风 +T 联动 )- T 设定

α 2.3 *(T 回风 +T 联动 )- T 设定

[0322] In particular, T 联动温降速率 ≥ 1.0℃ / min, T 联动修正_2 The preferred value range is 0.8℃ ~ 1.2℃; 0.5℃ / min ≤ T 联动温降速率 < 1.0℃ / min, T 联动修正_2 The preferred value range is 0.5℃ ~ 0.8℃; T 联动温降速率<0.5℃ / min, T 联动修正_2 The preferred value range is 0℃ ~ 0.5℃.

[0323] When T 回风 When < 25℃: If T 回风 -T 联动 ≥5℃, T 目标内环_联动智能 = T 回风 -0.5℃ +T 联动修正_3 If 3℃≤T 回风 -T 联动 <5℃, T 目标内环_联动智能 = T 回风 -1.5℃ +T 联动修正_3 If 1℃≤T 回风 -T 联动 <3℃, T 目标内环_联动智能 =T 回风 –

α 3.1 *(T 回风 +T 联动 )- T 设定

α 3.2 *(T 回风 +T 联动 )- T 设定

[0324] In particular, T 联动修正_3 The value of T is determined by the following control function: 联动修正_3 =λ*( T 回风 -T 联动 )+ μ.

[0325] In the formula, the preferred value range of λ is 0.35 ~ 0.65, and the preferred value range of μ is -0.20 ~ -0.45.

[0326] V. Custom + Smart Mode.

[0327] The user can simultaneously enable both Smart Mode and Smart Mode. When the user selects Custom + Smart Mode, the control mode module implements the control logic of Smart Mode while also taking into account the user's customized temperature control needs. Smart Mode provides the user with two modes: Custom + Standard Smart Mode and Custom + Linked Smart Mode.

[0328] (1) Custom + Standard Smart Mode.

[0329] When the user sets the custom + standard intelligent mode, the control mode module sends the T signal to the temperature control execution module. 自定义+标准智能 According to the following control model: T 自定义+标准智能 = T 自定义 + T 标准智能 .

[0330] In the formula, T 自定义 The value is determined based on the air conditioning temperature control parameters set by the user in the custom module, such as T. 设定_暖 T 设定_稍暖 T 设定_舒适 T 设定_稍冷 T 设定_偏冷 The specific parameters.

[0331] (2) Custom + Linkage Intelligent Mode.

[0332] When the user sets a custom + linked intelligent mode, the control mode module sends the T signal to the temperature control execution module. 自定义+联动智能 According to the following control model: T 自定义+联动智能 = T 自定义 + T 联动智能 .

[0333] In the formula, T 自定义 The value is determined based on the air conditioning temperature control parameters set by the user in the custom module, such as T. 设定_暖 T 设定_稍暖 T 设定_舒适 T 设定_稍冷 T 设定_偏冷 The specific parameters.

[0334] In summary, this solution has the following beneficial effects: 1. A target indoor ambient temperature intelligent control method based on return air temperature and wired controller temperature is proposed. By establishing a mathematical coupling model between wired controller temperature and return air outlet temperature, the ability of air conditioner to sense indoor temperature can be improved, and more precise temperature control can be achieved. 2. Users can adjust the temperature control effect according to their own temperature control preferences, which can make the air conditioner more suitable for the user's actual needs in actual operation scenarios; 3. A multimodal temperature control method that combines intelligent control and user-defined control is proposed, which can achieve precise temperature control while also taking into account the different needs of users.

[0336] The determination module is used to determine the control parameters corresponding to the control mode of each indoor unit among the multiple indoor units of the air conditioning equipment. The control mode includes custom mode and / or smart mode. The acquisition module is used to acquire air conditioning operating parameters during the operation of the air conditioning equipment in the control mode. The air conditioning operating parameters include the operating parameters of each of the at least two indoor units of the air conditioning equipment. The control module is used to determine the temperature control strategy based on the control parameters corresponding to the control mode and the air conditioner operating parameters, so as to correct the operating temperature of each indoor unit of the air conditioning equipment.

[0337] In some embodiments, the determining module is configured to determine the adjustment type corresponding to the custom mode in response to a triggering operation of the custom mode. The adjustment type is any one of warmer, slightly warmer, comfortable, slightly colder, and cooler. The parameters of the adjustment type include a first correction value corresponding to the first state and a range of second correction values ​​corresponding to the second state.
