[0002] In modern buildings, central air conditioning systems play a crucial role in indoor environmental comfort and are developing towards multi-unit collaboration and intelligence. However, current systems have many problems, such as most air conditioning units operating independently, lacking multi-unit topology association, and having a high risk of single-point failure. Once a unit fails, neighboring units cannot compensate, and temperature control in local areas will fail, affecting the user experience. Summary of the Invention

[0003] This application provides a control method and electronic device for an air conditioning unit. By combining topology model information to calculate the effective heat exchange quantity, the operating parameters of the auxiliary air conditioner are controlled based on the effective heat exchange quantity, thereby optimizing the operating strategy and realizing efficient linkage control of the air conditioner.

[0004] Firstly, a control method for an air conditioning unit is provided, including: Obtain the topology model information between the first air conditioner and the second air conditioner, wherein the topology model information includes: the air guide angle of the first air conditioner's blower, the azimuth angle of the second air conditioner's air receiving surface, and the distance information between the first air conditioner and the second air conditioner; Based on the air supply fan guide angle, the wind receiving surface azimuth angle and the distance information, the effective heat exchange amount between the first air conditioner and the second air conditioner is obtained. The effective heat exchange amount represents the heat that the first air conditioner can transfer to the working area of ​​the second air conditioner. Based on the effective heat exchange volume, an auxiliary air conditioner is determined to assist the second air conditioner. The operating parameters of the auxiliary air conditioner are obtained based on the operating parameters of the second air conditioner and environmental information; The operation of the auxiliary air conditioner is controlled based on its operating parameters.

[0005] The method provided in this application obtains topology model information between the first and second air conditioners, including the air supply fan guide angle, the azimuth angle of the air receiving surface, and distance information, and calculates the effective heat exchange volume accordingly. By quantifying the spatial relationship between units through topology modeling, it achieves multi-unit collaborative control, breaking the traditional "isolated unit" mode. It selects the auxiliary air conditioner based on the effective heat exchange volume and determines the operating parameters of the auxiliary air conditioner to control the operation of the auxiliary unit. Since the auxiliary unit can assist in adjusting the working area of ​​the second air conditioner, it can avoid local temperature control failure, achieve more precise and effective collaborative work between multiple units, and improve the overall operating efficiency and reliability of the air conditioning system.

[0006] In some embodiments, obtaining the effective heat exchange amount of the first air conditioner to the second air conditioner based on the air supply fan guide angle, the azimuth angle of the air receiving surface, and the distance information includes: The angle deviation is calculated based on the air guide angle of the blower and the azimuth angle of the wind-receiving surface. Based on the distance information, the distance decay effect parameters are calculated using an exponential decay model. The effective heat exchange between the first air conditioner and the second air conditioner is calculated based on the angle deviation and the distance attenuation effect.

[0007] The method provided in this application first calculates the angle deviation, which accurately measures the impact of the difference between the supply and receiving air directions on heat exchange. It then uses an exponential decay model to calculate the distance decay effect, consistent with the physical law that heat exchange decreases with increasing distance. By combining the angle deviation and distance decay effect to calculate the effective heat exchange volume, the calculation results are more consistent with reality, providing a reliable basis for subsequent precise linkage control.

[0008] In some embodiments, determining the auxiliary air conditioner that assists the second air conditioner based on the effective heat exchange capacity includes: Based on the distance information, the distance attenuation factor is calculated using a logarithmic attenuation model. Calculate the air guide angle matching degree based on the effective heat exchange amount; The weight of the first air conditioner is calculated based on the distance attenuation factor and the air guide angle matching degree; An auxiliary air conditioner is obtained based on the weights to assist the second air conditioner.

[0009] The method provided in this application uses a logarithmic decay model to calculate the distance attenuation factor, which more accurately reflects the impact of distance on air conditioning linkage; calculating the air guide angle matching degree can assess the degree of matching between the air supply angle and the air receiving demand. Combining the distance attenuation factor and the air guide angle matching degree to calculate the weight of the first air conditioner comprehensively considers multiple key factors, making the weight calculation more scientific and reasonable, and providing a basis for selecting the auxiliary air conditioner.

[0010] In some embodiments, obtaining the auxiliary air conditioner that assists the second air conditioner based on the weight includes: The first air conditioner with a weight less than a preset weight threshold is determined as the first air conditioner that does not receive assistance. The first air conditioner with a weight greater than or equal to a preset weight threshold is identified as the auxiliary air conditioner that assists the second air conditioner.

[0011] The method provided in this application uses a preset weight threshold to screen whether the first air conditioner participates in the linkage control, thereby avoiding interference to the system caused by the participation of the first air conditioner with too low a weight. This improves the efficiency and accuracy of the linkage control, ensures that the air conditioners participating in the linkage can truly play an effective role, and enhances the overall temperature control effect.

[0012] In some embodiments, the method further includes: The weights corresponding to each auxiliary air conditioner are sorted to obtain the sorting results; The auxiliary air conditioner with the highest weight in the ranking results is determined as the main auxiliary air conditioner that assists the second air conditioner. The auxiliary air conditioners other than the main and auxiliary air conditioners are defined as secondary auxiliary air conditioners that assist the second air conditioner.

[0013] The method provided in this application sorts auxiliary air conditioners by weight, determines the primary and secondary auxiliary air conditioners, and clarifies the role and status of each air conditioner in the linkage control. The primary and secondary air conditioners undertake the main auxiliary tasks, and the auxiliary units work together. This hierarchical control method can allocate resources more rationally, improve the flexibility and effectiveness of linkage control, and better meet the temperature control needs of the secondary air conditioner.

[0014] In some embodiments, obtaining the operating parameters of the auxiliary air conditioner based on the operating parameters of the second air conditioner and environmental information includes: The operating power of the auxiliary air conditioner is determined based on the operating parameters of the second air conditioner and environmental information. The operating power is allocated to the main auxiliary air conditioner and the secondary auxiliary air conditioner, wherein the operating power of the main auxiliary air conditioner is the highest.

[0015] The method provided in this application allocates operating power to the main and auxiliary air conditioners and specifies that the main and auxiliary air conditioners have the highest operating power, ensuring that the main and auxiliary air conditioners play a leading role in the control. At the same time, it rationally allocates the power of the auxiliary air conditioners, so that the entire linkage control process can proceed in an orderly manner. This can effectively assist the second air conditioner, avoid energy waste, and improve energy utilization efficiency.

[0016] In some embodiments, calculating the weight of the first air conditioner based on the distance attenuation factor and the air guide angle matching degree includes: The equipment power factor is obtained based on the equipment power of the first air conditioner and a pre-established first correspondence relationship, wherein the first correspondence relationship includes the correspondence relationship between the equipment power and the equipment power factor; The environmental thermal resistance factor is obtained based on the building structure between the second air conditioner and the first air conditioner and a pre-established second correspondence, wherein the second correspondence includes: the correspondence between the environmental thermal resistance factors of the building structure domain; Calculate the running time correction factor based on the running time of the first air conditioner; The weight of the first air conditioner is obtained by multiplying the distance attenuation factor, the air guide angle matching degree, the equipment power factor, the environmental thermal resistance factor, and the operating time correction factor.

[0017] The method provided in this application comprehensively considers multiple factors such as equipment power factor, environmental thermal resistance factor, and operating time correction factor to calculate the weight of the first air conditioner. It fully considers the influence of various factors such as equipment performance, environmental conditions, and operating history on the air conditioner linkage control, making the weight calculation more comprehensive and accurate, thereby providing a more reliable decision basis for linkage control.

[0018] In some embodiments, the method further includes: when a performance degradation or malfunction of the second air conditioner is detected, selecting the first air conditioner with the highest weight to compensate for the environmental conditioning capability caused by the performance degradation or malfunction of the second air conditioner.

[0019] The method provided in this application embodiment, when a performance degradation or malfunction of the second air conditioner is detected, selects the first air conditioner with the highest weight to compensate for the environmental regulation capability caused by the performance degradation or malfunction of the second air conditioner. This method can quickly and effectively utilize the optimal resources within the system to solve the problem, improve the system's emergency response capability and reliability, ensure that the indoor ambient temperature returns to normal as soon as possible, and reduce the impact on users.

[0020] Secondly, embodiments of this application further provide a control method for an air conditioning unit, including: Obtain the topology model information between the first air conditioner and the second air conditioner, wherein the topology model information includes: the air guide angle of the first air conditioner's blower, the azimuth angle of the second air conditioner's air receiving surface, and the distance information between the first air conditioner and the second air conditioner; Based on the air supply fan guide angle, the wind receiving surface azimuth angle and the distance information, the effective heat exchange amount between the first air conditioner and the second air conditioner is obtained. The effective heat exchange amount represents the heat that the first air conditioner can transfer to the working area of ​​the second air conditioner. If the effective heat exchange amount is less than a preset threshold, adjust the air guide angle of the first air conditioner's blower, or control the operation of other air conditioners besides the first air conditioner, or increase the operating time of the first air conditioner.

[0021] The method provided in this application offers various countermeasures when the effective heat exchange volume is less than a preset threshold. For example, adjusting the air guide angle of the blower can directly change the air supply direction and improve heat exchange efficiency; switching to other air conditioning auxiliary systems can quickly introduce a more suitable heat exchange source; and increasing the operating time can increase the total heat exchange volume. These measures provide flexible and diverse options for solving the problem of insufficient heat exchange, enhancing the adaptability and stability of the system.

The topology model information includes: the air guide angle of the first air conditioner's blower, the azimuth angle of the second air conditioner's air receiving surface, and the distance information between the first air conditioner and the second air conditioner. The module is used to obtain the effective heat exchange amount of the first air conditioner to the second air conditioner based on the air guide angle of the blower, the azimuth angle of the air receiving surface and the distance information. The effective heat exchange amount represents the heat that the first air conditioner can transfer to the working area of ​​the second air conditioner. A determining module is used to determine an auxiliary air conditioner that assists the second air conditioner based on the effective heat exchange volume.

[0034] Based on the problems in related technologies, this application provides a control method for an air conditioning unit that can be applied to electronic devices. The electronic devices may include: mobile phones, tablets, wearable devices, augmented reality (AR) / virtual reality (VR) devices, laptops, ultra-mobile personal computers (UMPCs), netbooks, personal digital assistants (PDAs), etc. This application does not impose any restrictions on the specific type of electronic device, and the electronic device can be used as the control system of the air conditioning system.

[0035] Figure 1 This is a schematic diagram illustrating the implementation flow of a control method for an air conditioning unit provided in an embodiment of this application, as shown below. Figure 1 As shown, it includes: Step S101: Obtain the topology model information between the first air conditioner and the second air conditioner. The topology model information includes: the air guide angle of the first air conditioner's blower, the azimuth angle of the second air conditioner's air receiving surface, and the distance information between the first air conditioner and the second air conditioner.

[0036] In this embodiment, the first and second air conditioners are interconnected and controlled in an air conditioning system. They can be air conditioning devices with different functions located in the same building, or different models and specifications of air conditioning devices in the same area. They influence each other through a specific topological relationship, jointly regulating indoor environmental parameters such as temperature and humidity. The first and second air conditioners can be units in a central air conditioning system, and there can be multiple first air conditioners. The topology model information describes the spatial position and angular relationship between the first and second air conditioners, including the air supply fan guide angle, the azimuth angle of the air receiving surface, and the distance between them. The topology model information can accurately depict the relative position of the two air conditioners in space and the geometric relationship of air supply and air receiving, providing basic data for subsequent calculation of effective heat exchange and realization of linkage control. In this embodiment, the air supply fan guide angle refers to the angle between the direction of the airflow delivered by the first air conditioner's air supply fan and a certain reference direction (such as the horizontal direction or a specific coordinate axis direction). This angle determines the directionality of the airflow. Different guide angles will cause the delivered airflow to reach different areas, affecting the heat exchange effect with the second air conditioner. The azimuth angle of the receiving surface is the angle of the surface of the second air conditioner receiving the airflow relative to a certain reference direction, reflecting the orientation of the receiving surface of the second air conditioner. It works in conjunction with the guide angle of the first air conditioner's blower to jointly affect the effective heat exchange between the two air conditioners. If the azimuth angle of the receiving surface and the guide angle of the blower are well matched, the heat exchange efficiency will be higher. Distance information is the straight-line distance or actual spatial distance between the first and second air conditioners. Distance is one of the important factors affecting heat exchange. Generally speaking, the greater the distance, the more heat is lost during the heat exchange process, and the smaller the effective heat exchange volume will be. In some embodiments, the topology model information may also include the air conditioner position, which can be represented as XYZ. Then the topology model information can be represented as: M=(X, Y, Z, θ1, θ2, d), where (X, Y, Z) is the position; θ1 is the guide angle of the blower; θ2 is the azimuth angle of the receiving surface; and d is the distance information.

[0037] In this embodiment, an angle sensor can be installed at the blower of the first air conditioner to measure the blower's guide angle in real time; an azimuth sensor can be installed on the windward surface of the second air conditioner to measure the azimuth angle of the windward surface; simultaneously, distance measuring devices (such as laser rangefinders, ultrasonic rangefinders, etc.) can be installed on both air conditioners to measure the distance information between them. These sensors transmit the collected data to the central control system.

[0038] In some cases, if sensor installation costs are too high or environmental conditions do not allow for sensor installation, this information can be obtained manually and then input into the control system through an interface. Indoor positioning technology can be used to obtain the three-dimensional coordinates (X, Y, Z) of each air conditioning unit. Simultaneously, the straight-line distance d between units can be collected. An air guide angle sensor (such as a Hall encoder / gyroscope) can be installed on each air conditioner to obtain the air supply angle θ1 in real time. The azimuth angle θ2 of the air-receiving surface of adjacent units can be determined through modeling or camera visual calibration.

[0039] Step S102: Based on the air supply fan guide angle, the azimuth angle of the air receiving surface and the distance information, the effective heat exchange amount between the first air conditioner and the second air conditioner is obtained. The effective heat exchange amount represents the amount of heat that the first air conditioner can transfer to the working area of ​​the second air conditioner.

[0040] In this embodiment, the effective heat exchange capacity represents the amount of heat that the first air conditioner can actually transfer to the area of ​​action of the second air conditioner under specific conditions (considering factors such as the air guide angle of the blower, the azimuth angle of the air receiving surface, and the distance). It is a key indicator for measuring the heat exchange effect between the two air conditioners. The larger the effective heat exchange capacity, the stronger the auxiliary effect of the first air conditioner on the second air conditioner, and the more conducive it is to achieving the linkage control target.

[0041] In this embodiment, an effective heat exchange calculation model can be established based on thermodynamic and fluid mechanics principles, comprehensively considering the fan guide angle, the azimuth angle of the receiving surface, and distance information. For example, a composite model based on angle deviation and distance attenuation can be used. First, the angle deviation between the fan guide angle and the azimuth angle of the receiving surface is calculated. Then, based on the distance information, an exponential attenuation model is used to calculate the distance attenuation effect. Finally, the angle deviation and distance attenuation effect are comprehensively calculated to obtain the effective heat exchange. The collected fan guide angle, azimuth angle of the receiving surface, and distance information can be substituted into the established mathematical model, and the effective heat exchange from the first air conditioner to the second air conditioner can be calculated.

[0042] Step S103: Determine an auxiliary air conditioner to assist the second air conditioner based on the effective heat exchange amount.

[0043] In this embodiment, the auxiliary air conditioner is a unit selected based on effective heat exchange capacity that can provide heat compensation for the second air conditioner. The auxiliary unit can be further divided into a main auxiliary air conditioner and a secondary auxiliary air conditioner.

[0044] In this embodiment of the application, an effective heat exchange threshold can be set, and only the first air conditioner with a value greater than the effective heat exchange threshold can be retained as an auxiliary unit.

[0045] Step S104: Obtain the operating parameters of the auxiliary air conditioner based on the operating parameters of the second air conditioner and environmental information.

[0046] In this embodiment, operating parameters may include: temperature setpoint, fan speed, operating power, compressor frequency, etc., which directly determine the air conditioner's output capacity. Environmental information may include: indoor and outdoor temperature and humidity, light intensity, personnel density, etc., which affect the parameter adjustment strategy of the auxiliary air conditioner.

[0047] In this embodiment, the heat gap of the second air conditioner can be determined based on its current operating parameters and environmental information, and the operating parameters of the auxiliary air conditioner can be obtained through the heat gap. If there is a single auxiliary air conditioner, its operating power is directly adjusted to meet the heat gap. If there are multiple auxiliary air conditioners, the power can be allocated according to a set weight to obtain the operating parameters of the auxiliary air conditioners. For example, the heat gap of the second air conditioner is 2kW, and there are two auxiliary air conditioners (effective heat exchange capacity of 1.5kW and 1.2kW): the operating power of the main auxiliary air conditioner (1.5kW) is set to 1.4kW, the operating power of the secondary auxiliary air conditioner (1.2kW) is set to 0.6kW, and the total compensation is 1.4 + 0.6 = 2kW.

[0048] Step S105: Control the operation of the auxiliary air conditioner based on its operating parameters.

[0049] In this embodiment, control commands can be generated based on operating parameters and sent to the auxiliary air conditioner to adjust its operating parameters, such as adjusting the temperature setpoint and compressor frequency.

[0050] The method provided in this application obtains topology model information between the first and second air conditioners, including the air supply fan guide angle, the azimuth angle of the air receiving surface, and distance information. Based on this, it calculates the effective heat exchange volume. By quantifying the spatial relationship between units through topology modeling, it achieves multi-unit collaborative control, breaking the traditional "isolated unit" mode. By selecting the auxiliary air conditioner based on the effective heat exchange volume and determining the operating parameters of the auxiliary air conditioner to control the operation of the auxiliary unit, it can avoid local temperature control failure, reduce ineffective energy consumption, and achieve more precise and effective collaborative work between multiple units, thereby improving the overall operating efficiency and reliability of the air conditioning system. In addition, by considering spatial factors such as air supply angle, distance, and room layout for linkage control, it can avoid some units from operating under unbalanced or full load for a long time, reducing equipment aging.

[0051] In some embodiments, step S102 can be implemented by the following steps: Step S1021: Calculate the angle deviation based on the air supply fan guide angle and the azimuth angle of the wind-receiving surface.

[0052] In this embodiment, the angle deviation is calculated from the air supply fan guide angle and the azimuth angle of the air receiving surface, representing the degree of deviation between the air supply direction of the first air conditioner and the orientation of the air receiving surface of the second air conditioner. The larger the angle deviation, the worse the match between the air supply direction and the orientation of the air receiving surface, and the lower the heat exchange efficiency may be.

[0053] In this embodiment of the application, the wind guide angle of the blower is θ1, the azimuth angle of the wind-receiving surface is θ2, and the angle deviation Δθ can be obtained by simple mathematical calculation, for example, Δθ = |θ1- θ2|. The absolute value is taken to eliminate the positive and negative influence of the direction, and only the magnitude of the deviation is considered.

[0054] Step S1022: Calculate the distance decay effect parameters using an exponential decay model based on the distance information.

[0055] In this embodiment, the distance attenuation effect parameter is calculated using an exponential attenuation model based on distance information. It describes the phenomenon that the effective heat exchange decreases exponentially as the distance between the first and second air conditioners increases. The distance attenuation effect parameter reflects the hindering effect of distance on heat exchange; the greater the distance, the more significant the attenuation effect.

[0056] In this embodiment, the general form of the exponential decay model is y=e -kd , where y represents the distance attenuation effect, d represents the distance information, and k can be the environmental attenuation coefficient.

[0057] Step S1023: Calculate the effective heat exchange between the first air conditioner and the second air conditioner based on the angle deviation and distance attenuation effect parameters.

[0058] In this embodiment of the application, the influence of angle deviation and distance attenuation effect parameters on the effective heat exchange can be comprehensively considered to establish a comprehensive calculation model. For example, the effective heat exchange can be calculated using the following formula: ; The heat exchange efficiency is highest when the air guide angle of the blower is perfectly matched with the azimuth angle of the air receiving surface (Δθ=0); the larger Δθ is, the lower the Q value; the larger d is, the exponential decay leads to a decrease in thermal efficiency.

[0059] The method provided in this application, by calculating the angle deviation and distance attenuation effect parameters separately and comprehensively considering their impact on the effective heat exchange, can more accurately describe the heat exchange process between the first and second air conditioners. Accurate calculation results of the effective heat exchange can lead to more precise linkage control. The central control system can adjust the operating parameters of the first and second air conditioners, such as air volume and temperature settings, more rationally based on the calculated effective heat exchange, thereby achieving better collaborative performance and improving the comfort and stability of the indoor environment.

[0060] In some embodiments, Figure 2 FIG. is a schematic diagram of the implementation process of step S103 provided by an embodiment of the present application. As Figure 2 shown, step S103 can be implemented through the following steps: Step S1031, calculate the distance attenuation factor based on the distance information using a logarithmic attenuation model.

[0061] In an embodiment of the present application, the distance attenuation factor is calculated based on the distance information using a logarithmic attenuation model, and is a parameter used to describe that as the distance between the first air conditioner and the second air conditioner increases, the influence degree of the first air conditioner on the second air conditioner decreases logarithmically. The distance attenuation factor reflects the degree of weakening of the effect of the distance on the first air conditioner in the air conditioner linkage control. The distance attenuation factor can be calculated using the following formula: W_d = e (-0.05d) , where W_d is the distance attenuation factor.

[0062] Step S1032, calculate the air deflector angle matching degree based on the effective heat exchange amount.

[0063] In an embodiment of the present application, the air deflector angle matching degree can be obtained by calculating based on the effective heat exchange amount, and is an index used to measure the matching degree between the air deflector angle of the first air conditioner's blower and the azimuth angle of the wind-receiving surface of the second air conditioner. The higher the air deflector angle matching degree, the more the air supply direction of the first air conditioner matches the wind-receiving surface orientation of the second air conditioner, the higher the heat exchange efficiency, and the more important the role of the first air conditioner in the linkage control.

[0064] In an embodiment of the present application, the air deflector angle matching degree Wangle = f(Q), and different Q values can correspond to different air deflector angle matching degrees. For example, when Q≥0.8, f(Q) = 1.5, that is, Wangle is 1.5; when 0.3<Q<0.8, Wangle = 1.0; when Q≤0.3, Wangle = 0.3. Of course, in some embodiments, it can also be set to different values.

[0065] Step S1033, calculate the weight of the first air conditioner based on the distance attenuation factor and the air deflector angle matching degree.

[0066] In an embodiment of the present application, the weight is calculated based on the distance attenuation factor and the air deflector angle matching degree, and is used to represent the importance or influence degree of the first air conditioner in the linkage control. The greater the weight, the greater the contribution of the first air conditioner to the adjustment of the operating parameters of the second air conditioner in the linkage control.

[0067] In an embodiment of the present application, the influence of the distance attenuation factor and the air deflector angle matching degree on the weight of the first air conditioner can be comprehensively considered, and a weight calculation model can be established. The weight calculation model can be the multiplication of two weights.

[0068] Step S1034: Based on the weights, obtain the auxiliary air conditioner that assists the second air conditioner.

[0069] In this embodiment of the application, a first air conditioner with a weight less than a preset weight threshold can be determined as a first air conditioner that does not provide assistance; and a first air conditioner with a weight greater than or equal to a preset weight threshold can be determined as an auxiliary air conditioner that assists the second air conditioner.

[0070] The method provided in this application, by calculating the distance attenuation factor and the air guide angle matching degree, and calculating the weight of the first air conditioner based on them, can more accurately consider the influence of distance and air guide angle on the air conditioner linkage control, and accurately calculate the weight. Accurate weight calculation can make the linkage control more reasonable and avoid unnecessary energy waste.

[0071] In some embodiments, Figure 3 This application provides a flowchart illustrating the process of determining the main auxiliary air conditioner and the secondary auxiliary air conditioner, as shown in the embodiments of this application. Figure 3 As shown, after step S1034, the method further includes: Step S341: Sort the weights corresponding to each auxiliary air conditioner to obtain the sorting result.

[0072] In this embodiment, quicksort or bubble sort is used to arrange the auxiliary air conditioners from high to low according to their weight values, thereby obtaining the sorting result.

[0073] Step S342: The auxiliary air conditioner with the highest weight in the sorting results is determined as the main auxiliary air conditioner that assists the second air conditioner.

[0074] In this embodiment, the main and auxiliary air conditioners are the units that undertake the main heat compensation task among multiple auxiliary air conditioners, and usually have the highest weight.

[0075] In this embodiment of the application, the auxiliary air conditioner with the largest weight in the sorting results can be directly selected as the main and auxiliary air conditioners.

[0076] Step S343: The auxiliary air conditioner other than the main auxiliary air conditioner is identified as the secondary auxiliary air conditioner that assists the second air conditioner.

[0077] In this embodiment, the auxiliary air conditioner is any other air conditioner that participates in the auxiliary process besides the main auxiliary air conditioner, and undertakes the task of compensating for residual heat.

[0078] In this embodiment of the application, all auxiliary air conditioners other than the main auxiliary air conditioner in the sorting result can be marked as secondary auxiliary air conditioners.

[0079] For example, the second air conditioner is A, and the first air conditioner includes B, C, and D, with B having a weight of 2.04, C having a weight of 1.65, and D having a weight of 0.98. B is preferentially selected as the main auxiliary unit for A, C is selected as the secondary auxiliary unit for A, and D is not selected as an auxiliary unit due to insufficient weight.

[0080] The method provided in this application divides auxiliary air conditioners into primary and secondary auxiliary air conditioners, clarifying their different roles and tasks in the linkage control according to their weights. The primary auxiliary air conditioner undertakes the main auxiliary tasks, fully leveraging its advantages to provide the most effective support to the secondary air conditioner; the secondary auxiliary air conditioner collaborates with the main unit to complete auxiliary work. This reasonable allocation method avoids all air conditioners exerting equal effort, improving the execution efficiency of auxiliary tasks.

[0081] In some embodiments, step S104 can be implemented by the following steps: determining the operating power of the auxiliary air conditioner based on the operating parameters and environmental information of the second air conditioner; allocating operating power to the main auxiliary air conditioner and the secondary auxiliary air conditioner, wherein the main auxiliary air conditioner has the highest operating power.

[0082] In this embodiment, the operating parameters of the second air conditioner reflect the quantitative indicators of the current working state of the second air conditioner and are used to calculate its heat gap or performance requirements. The operating power of the auxiliary air conditioner is the electrical or thermal power that the auxiliary air conditioner needs to output to meet the requirements of the second air conditioner.

[0083] In this embodiment, the first step is to obtain the current operating status and environmental information of the second air conditioner, such as temperature, humidity, and cooling / heating load. This data can be collected in real time by sensors installed on the second air conditioner and transmitted to the air conditioning control system. Based on the equipment parameters of the main and auxiliary air conditioners, such as rated power and energy efficiency ratio, and their current operating status (e.g., whether they are operating at full load or experiencing malfunctions), their auxiliary capabilities are assessed. Combining the operating parameters and environmental information of the second air conditioner, the operating power of the auxiliary air conditioners is determined, and a reasonable power allocation strategy is formulated. Generally, the main and auxiliary air conditioners undertake the primary auxiliary tasks and are therefore allocated higher operating power; the auxiliary air conditioners are allocated relatively lower operating power based on their capacity and remaining auxiliary needs. For example, a weighted allocation method can be used, with the main unit having the highest weight and receiving the largest power allocation; the auxiliary units are allocated their remaining power according to their weights. In the air conditioning control system, according to the formulated power allocation strategy, corresponding power control commands are sent to the main and auxiliary air conditioners to adjust their operating power. After receiving the operating power control commands from the air conditioning control system, the main and auxiliary air conditioners parse them into specific control parameters. Based on control parameters, the main and auxiliary air conditioning units adjust their operating states, such as compressor speed and fan speed, to achieve the allocated operating power. For example, if the main unit is allocated a higher operating power, it will increase the compressor speed and the refrigerant circulation, thereby increasing the cooling or heating capacity.

[0084] The method provided in this application, by rationally allocating the operating power of the main and auxiliary air conditioners, can fully leverage the advantages of the main and auxiliary air conditioners, enabling them to provide the most effective auxiliary support to the second air conditioner in the linkage control. Simultaneously, the auxiliary air conditioner can also work in coordination with the main unit according to its own capabilities to jointly meet the operating needs of the second air conditioner, thereby improving the overall auxiliary effect of the linkage control and enabling the second air conditioner to operate more stably and efficiently. Allocating operating power to the main and auxiliary air conditioners based on the operating parameters and environmental information of the second air conditioner avoids unnecessary energy waste. The main and auxiliary air conditioners will not over-operate but will operate at the most appropriate power, improving energy utilization efficiency, reducing the energy consumption of the air conditioning system, and meeting the requirements of energy conservation and emission reduction.

[0085] In some embodiments, Figure 4 A flowchart illustrating step S1033 provided in an embodiment of this application is shown below. Figure 4 As shown, step S1033 can be achieved through the following steps: Step S331: Obtain the equipment power factor based on the equipment power of the first air conditioner and the pre-established first correspondence relationship, wherein the first correspondence relationship includes the correspondence relationship between the equipment power and the equipment power factor.

[0086] In this embodiment, the device power factor is a parameter obtained based on the device power of the first air conditioner through a pre-established first correspondence relationship. It reflects the impact of the first air conditioner's device power on its auxiliary capability in linkage control; the higher the device power, the higher the device power factor, indicating that the air conditioner is more advantageous in providing cooling or heating capabilities. The first correspondence relationship is the relationship between device power and device power factor. This relationship is established through extensive experimental data, theoretical analysis, or practical operating experience, and is used to convert the device power of the first air conditioner into a device power factor that reflects its auxiliary capability in linkage control.

[0087] In this embodiment, the device power information of the first air conditioner can be retrieved, and a pre-established first correspondence relationship can be found. This correspondence relationship can be in tabular form, listing the device power factors corresponding to different device power ranges; or it can be in mathematical function form, directly calculating the device power factor by inputting the device power value. Based on the device power of the first air conditioner, the corresponding device power factor is found in the first correspondence relationship.

[0088] Step S332: Based on the building structure between the second air conditioner and the first air conditioner and the pre-established second correspondence, the environmental thermal resistance factor is obtained, wherein the second correspondence includes: the correspondence between the environmental thermal resistance factors of the building structure domain.

[0089] In this embodiment, the building structure is a comprehensive reflection of factors such as the architectural layout, wall materials, and the location and size of doors and windows in the spaces where the second and first air conditioners are located. Different building structures affect heat transfer and distribution, thus affecting the auxiliary effect of the first air conditioner on the second air conditioner. The environmental thermal resistance factor is a parameter obtained through a pre-established second correspondence based on the building structure between the second and first air conditioners. It reflects the degree to which the building structure hinders heat transfer; the larger the environmental thermal resistance factor, the greater the obstruction to heat transfer by the building structure, and the greater the difficulty for the first air conditioner to assist the second air conditioner. If there is a thick solid wall between the first and second air conditioners, heat transfer is difficult, and the environmental thermal resistance factor obtained according to the second correspondence will be larger; if there is a transparent glass partition between them, heat transfer is relatively easy, and the environmental thermal resistance factor will be smaller. The second correspondence is the correspondence between the building structure and the environmental thermal resistance factor. By studying the heat transfer characteristics under different building structures, this correspondence is established to quickly determine the environmental thermal resistance factor based on the actual building structure.

[0090] In this embodiment, a detailed analysis of the building structure between the second air conditioner and the first air conditioner is performed, including determining structural features such as wall material, door and window types and locations, and partition details. The building structure can be pre-stored in an electronic device. A pre-established second correspondence is searched; this correspondence may be a database containing various building structure types and their corresponding environmental thermal resistance factors, or a mathematical model for calculating environmental thermal resistance factors based on building structure characteristic parameters. Based on the analyzed building structure features, the corresponding environmental thermal resistance factor is queried or calculated from the second correspondence.

[0091] Step S333: Calculate the running time correction factor based on the running time of the first air conditioner.

[0092] In this embodiment, the running time correction factor is a parameter calculated based on the running time of the first air conditioner, used to correct the weight of the first air conditioner. The longer the running time of the first air conditioner, the more wear and aging its components may occur, and its performance may decline. The running time correction factor can quantify and adjust this impact.

[0093] In this embodiment, the operating time information of the first air conditioner can be obtained through the operating time data recorded by the air conditioning control system. The operating time correction factor is calculated according to a pre-set relationship rule between operating time and operating time correction factor. Based on the actual operating time of the first air conditioner, the operating time correction factor is calculated according to the aforementioned rule.

[0094] Step S334: Multiply the distance attenuation factor, air guide angle matching degree, equipment power factor, environmental thermal resistance factor and running time correction factor to obtain the weight of the first air conditioner.

[0095] In this embodiment, it is ensured that the values ​​of five parameters—distance attenuation factor, air guide angle matching degree, equipment power factor, environmental thermal resistance factor, and operating time correction factor—have been obtained. These five parameters are then simply added together: the weight of the first air conditioner = distance attenuation factor + air guide angle matching degree + equipment power factor + environmental thermal resistance factor + operating time correction factor.

[0096] In this embodiment, Wtotal can be expressed by the following formula: Wtotal = Wpower * Wangle * Wdistance * Wthermal * Wruntime; where Wpower: equipment power factor; Wangle: airflow angle matching degree; Wdistance: distance attenuation factor; Wthermal: environmental thermal resistance (solid wall, glass partition, open space); Wruntime: running time correction factor. In some embodiments, regional heat load demand can also be considered when calculating the weights.

[0097] Table 1 is a definition table of influence factors and parameters provided in the embodiments of this application, as shown in Table 1:

[0098] The method provided in this application comprehensively considers multiple factors affecting the ability of the first air conditioner to assist the second air conditioner, such as distance, airflow angle, equipment power, building structure, and operating time. By quantifying these factors into different elements and calculating their weights, the auxiliary capability of the first air conditioner in the linkage control can be evaluated more comprehensively and accurately, avoiding the one-sidedness of single-factor evaluation. Since the weight calculation considers multiple key factors, the auxiliary tasks of the first air conditioner to the second air conditioner can be more rationally selected and allocated in the linkage control. The first air conditioner with a higher weight can better leverage its advantages, providing more effective assistance to the second air conditioner, thereby improving the linkage control effect of the entire air conditioning system and making the indoor environment more comfortable and stable. The degree of influence of each factor may vary under different building environments and air conditioning usage scenarios. This method, by establishing correspondences and calculating factors, can flexibly adjust the weight calculation according to the actual situation, adapting to various building structures and usage conditions. For example, in buildings of different materials, the environmental thermal resistance factor will accurately reflect the influence of the building structure on heat transfer according to the actual situation, making the weight calculation more in line with actual needs.

[0099] In some embodiments, the method further includes: Step S106: If the performance of the second air conditioner is detected to be degraded or malfunctioning, the first air conditioner with the highest weight is selected to compensate for the environmental regulation capability caused by the performance degradation or malfunction of the second air conditioner.

[0100] In this embodiment, the environmental regulation capability to compensate for the performance degradation or malfunction of the second air conditioner is achieved by the first air conditioner adjusting its own operating parameters (such as air volume, temperature setting, operating mode, etc.) to provide additional cooling or heating capacity to the area served by the second air conditioner when the performance degradation or malfunction of the second air conditioner occurs, so as to compensate for the insufficient environmental regulation capability caused by the performance degradation or malfunction of the second air conditioner and restore the indoor environmental parameters (temperature, humidity, etc.) to a suitable range.

[0101] In this embodiment, the air conditioning control system monitors the operating parameters of the second air conditioner in real time, such as cooling capacity, heating capacity, supply air temperature, return air temperature, and compressor operating status. These real-time parameters are compared with a pre-set range of normal performance parameters. For example, for the second air conditioner in cooling mode, if the outlet air temperature is higher than the upper limit of the set normal outlet air temperature range, or the cooling capacity is lower than the normal cooling capacity by a certain percentage (e.g., 80%), it is determined that the air conditioner's performance has deteriorated. The fault diagnosis function built into the air conditioning system or additional fault detection sensors can be used to detect whether the second air conditioner has malfunctioned. Common fault detection methods include checking whether the compressor current and voltage are normal, whether the sensors are malfunctioning, and whether the refrigerant is leaking. When fault signals such as compressor stoppage, abnormal sensor data, or low refrigerant pressure are detected, it is determined that the second air conditioner has malfunctioned. The weight data of all first air conditioners can be read from the database, and the first air conditioner with the highest weight can be found through a comparison algorithm (e.g., simple numerical comparison). The control system sends control commands to the first air conditioner with the highest weight, adjusting the operating parameters of the first air conditioner according to the performance degradation or malfunction of the second air conditioner. If the performance of the second air conditioner deteriorates, for example, due to insufficient cooling capacity, the first air conditioner can appropriately increase its cooling power, increase airflow, and lower the outlet air temperature to supplement the cooling capacity of the area served by the second air conditioner. If the second air conditioner malfunctions and stops operating, the first air conditioner needs to take over the environmental conditioning tasks originally handled by the second air conditioner, adjusting its operating mode (such as switching from partial load operation to full load operation), temperature settings, and other parameters according to the needs of that area to ensure that indoor environmental parameters are maintained within a comfortable range.

[0102] The method provided in this application can quickly detect and immediately activate a linkage control mechanism when the second air conditioner experiences performance degradation or malfunction, selecting the first air conditioner with the highest weight for compensation. This rapid response can prevent indoor environmental deterioration caused by problems with the second air conditioner, maintain indoor comfort in a timely manner, and improve the user experience. By selecting the first air conditioner for compensation based on weight, it ensures that the most capable (highest weight) first air conditioner is assigned to the second air conditioner task requiring compensation. This fully utilizes the advantages of the first air conditioner, avoids resource waste, and improves the operating efficiency of the entire air conditioning system. Timely compensation for the second air conditioner can reduce equipment damage or other losses that may be caused by environmental deterioration, and reduce the frequency of equipment repair and replacement.

[0103] Based on the foregoing embodiments, this application further provides a control method for an air conditioning unit. Figure 5 This is a schematic diagram illustrating the implementation flow of a control method for an air conditioning unit provided in an embodiment of this application, as shown below. Figure 5 As shown, it includes: Step S501: Obtain the topology model information between the first air conditioner and the second air conditioner, wherein the topology model information includes: the air guide angle of the first air conditioner's blower, the azimuth angle of the second air conditioner's air receiving surface, and the distance information between the first air conditioner and the second air conditioner.

[0104] Step S502: Based on the air guide angle of the blower, the azimuth angle of the air receiving surface and the distance information, the effective heat exchange amount between the first air conditioner and the second air conditioner is obtained. The effective heat exchange amount represents the amount of heat that the first air conditioner can transfer to the working area of ​​the second air conditioner. Step S503: If the effective heat exchange amount is less than a preset threshold, adjust the air guide angle of the first air conditioner's blower, or control the operation of other air conditioners besides the first air conditioner, or increase the operating time of the first air conditioner.

[0105] In this embodiment, the preset threshold is a pre-set critical value used to determine whether the effective heat exchange capacity meets the requirements. When the effective heat exchange capacity is less than this threshold, it means that the current air conditioner does not meet the auxiliary requirements; when the effective heat exchange capacity is greater than or equal to this threshold, the auxiliary requirements are met.

[0106] In this embodiment of the application, when the effective heat exchange amount is detected to be less than a preset threshold, the control system determines the size of the air guide angle that needs to be adjusted according to the actual indoor environment and the preset control strategy, so as to increase the effective heat exchange amount and meet the auxiliary requirements, thereby enabling the second air conditioner to provide assistance.

[0107] In this embodiment, the control system first evaluates other air conditioners in the system to obtain weights, and then selects other air conditioners to assist the second air conditioner based on these weights.

[0108] For example, there are two air conditioners, A and B. When θ1=30° and θ2=30°, they are perfectly matched. d=10m and k=0.05, and Q=0.606 is calculated. At this time, Q is greater than the preset threshold, so the auxiliary requirements are met and it can be used for auxiliary purposes. However, when Q is less than the threshold, it is determined that the auxiliary conditions are not met. At this time, Δθ may be too large, so the air guide plate is automatically adjusted or the unit is switched to another unit.

[0109] In this embodiment, when the effective heat exchange rate is detected to be less than a preset threshold, the air conditioning control system calculates the required increase in operating time based on factors such as the difference between the current effective heat exchange rate and the threshold, and the needs of the indoor environment. For example, if the difference is large, a longer operating time may be required; if the difference is small, the increased operating time will be relatively short. For instance, θ1 = 30°, θ2 = 60° (deviation 30°), Q value ≈ 0.8 (partial air supply effective). In this case, the operating time can be extended to compensate.

[0110] In the method provided by the embodiment of the present application, when the effective heat exchange amount is less than the preset threshold, by adjusting the air deflector angle of the blower of the first air conditioner, the air supply can act more precisely on the area to be adjusted, improving the heat exchange efficiency of this area; switching to other air conditioners for assistance can increase the overall cooling or heating capacity; increasing the operating duration of the first air conditioner can increase the time for heat exchange. The combined effect of these measures can effectively improve the adjustment effect of the indoor environment. Multiple linkage control methods (adjusting the air deflector angle, switching the auxiliary air conditioner, increasing the operating duration) can be flexibly selected and combined according to different actual situations.

[0111] Based on the foregoing embodiments, the embodiment of the present application provides a specific example. When there are four units A, B, C, and D in the air conditioning system, the relationship table between the units is as follows: , Figure 6 FIG. is a schematic diagram of the distance between units provided by the embodiment of the present application. As Figure 6 shown, Room 101: Air conditioner A (air deflector 1) and air conditioner B (air deflector 3): 8 meters; Room 101: Air conditioner A (air deflector 1) and air conditioner C (air deflector 3): 10 meters; Room 101: Air conditioner A (air deflector 1) and air conditioner D (air deflector 3): 14 meters; Room 101: Air conditioner B (air deflector 3) and air conditioner A (air deflector 1): 8 meters; Room 101: Air conditioner B (air deflector 2) and air conditioner C (air deflector 4): 5 meters; Room 101: Air conditioner B (air deflector 1) and air conditioner D (air deflector 3): 10 meters; Room 101: Air conditioner C (air deflector 3) and air conditioner A (air deflector 1): 10 meters; Room 101: Air conditioner C (air deflector 4) and air conditioner B (air deflector 2): 5 meters; Room 101: Air conditioner C (air deflector 1) and air conditioner D (air deflector 3): 8 meters; Room 101: Air conditioner D (air deflector 3) and air conditioner A (air deflector 1): 14 meters; Room 101: Air conditioner D (air deflector 3) and air conditioner B (air deflector 1): 10 meters; Room 101: Air conditioner D (air deflector 3) and air conditioner C (air deflector 1): 8 meters. Substitute the parameters into the calculation respectively. Taking A and B as an example, known conditions: Air conditioner A: high-power unit (1.2), air deflector blowing directly (1.5), 8 meters away from air conditioner B; partition type: solid wall (0.5); operating status: Air conditioner A has been running for 6 hours (W_t = 1 - 0.02×6 = 0.88); temperature control requirement: high-temperature area (1.3); comprehensive weight calculation: W_total (AB) = 1.2 (equipment power factor) × 1.5 (air guide plate matching degree) × [1 - (8 × 0.05 × 0.5)] (distance & thermal resistance attenuation factor) × 0.88 (running time correction factor) × 1.3 (heat load) = 1.2 × 1.5 × (1 - 0.2) × 0.88 × 1.3 = 1.2 × 1.5 × 0.8 × 0.88 × 1.3 = 2.04.

[0112] Each pair is calculated and its node weight is integrated (comprehensive for each unit). Then, it is judged. If W_total = 2.04 ≥ 2.0 (maximum), then the thermal impact path of air conditioner A on air conditioner B is "strongly correlated," and A is prioritized as the host unit. Next, the system considers two dimensions: Real-time temperature feedback: If the temperature rise rate in area B is less than the expected value of 15%, the air guide vane weight is automatically increased by 0.2, further increasing A's priority. Angle matching check: If Δθ > 15°, the system will attempt to fine-tune the angle of A's air guide vane to make it closer to B's airflow direction; if Δθ > 45°, it is determined as an invalid path, and other nearby units are selected instead. In normal mode, more load is allocated to B, and C and D bear the remaining load according to their weights.

[0113] The method provided in this application, for the first time, combines the air supply fan guide angle, the air receiving surface azimuth angle, and spatial distance to establish a six-dimensional spatial relationship model (XYZ coordinates + air supply fan guide angle + air receiving surface azimuth angle + distance), thereby achieving a precise characterization of the thermal effect between air conditioners. By defining the angle difference (Δθ) between the air supply angle and the air receiving angle, an angle matching threshold (≤15° for effective air supply) is proposed, significantly improving the air supply coverage and heat exchange efficiency. By comprehensively considering multiple factors such as equipment power, guide angle matching degree, distance attenuation, regional heat load, and environmental thermal resistance, a thermal influence weight table is established to achieve more refined multi-machine collaborative control. The method provided in this application embodiment only requires adding an air guide angle detection device (such as a Hall encoder or gyroscope) to the existing air conditioner, which can be embedded into the existing controller firmware. The modification cost is low and it is suitable for large-scale application.
