Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention.

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0050] In this embodiment, "and / or" describes the relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. Additionally, the character " / ", unless otherwise specified, generally indicates that the preceding and following associated objects have an "or" relationship.

[0051] In this application, the term "exemplary" is used to mean "serving as an example, illustration, or description." Any embodiment described as "exemplary" in this application is not necessarily to be construed as being more preferred or advantageous than other embodiments. The following description is provided to enable any person skilled in the art to make and use the invention. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the invention can be made without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the invention with unnecessary detail. Therefore, the invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0052] Currently, intelligent control systems are widely used in various air conditioning fields, but they still lack the ability to intelligently prevent condensation in base station air conditioners. Most base station indoor anti-condensation solutions mainly involve increasing fan speed, and research on this is still needed. At present, most base station air conditioners have both indoor and outdoor unit boards installed in the indoor unit, and the refrigerant pipes are close to the back of the electronic control board. When the electronic control system is running, the temperature is easy to rise, while the refrigerant temperature is low, which can easily cause condensation on the electronic control board. In order to prevent condensation in base station air conditioners, most methods rely on high air volume output from the indoor unit, which is generally ineffective. It can only dry the condensate at the air outlet of the indoor unit, but ignores the condensation potential of the indoor electronic control board. Especially under prolonged low-temperature cooling, base station air conditioners, operating within the high-temperature environment of the base station, are more prone to condensation, affecting circuit board stability. To address this issue, this invention proposes a method to infer the condensation prevention temperature on the indoor unit based on the internal ambient temperature and internal pipe temperature. This ensures the cooling effect of the entire base station air conditioner while maintaining low-temperature cooling, and simultaneously adjusts the fan speed and electronic expansion valve opening in real time to prevent frequency drops that could impact cooling efficiency and prevent condensation. An intelligent control scheme for electronically controlled condensation under low-temperature cooling is established. This significantly impacts the stability of base station air conditioner operation; therefore, this invention proposes an intelligent control method that indirectly controls the internal electronic control system to avoid approaching the dew point under low-temperature cooling conditions, thus preventing the stability issues caused by electronically controlled condensation.

[0053] To address the issue that condensation can easily occur in the indoor electrical control components of base station air conditioners under excessively low outdoor temperatures, thus affecting the stability of the air conditioner's operation, this invention proposes a method based on an internal sensor to infer the temperature of the condensation inside. This avoids the waste of unnecessary increased fan power without achieving good anti-condensation effects, thereby improving the stability and safety of the base station air conditioner.

[0054] Specifically, this application provides an air conditioning anti-condensation control method, device, air conditioner, and computer-readable storage medium (the computer-readable storage medium may be referred to as the storage medium), which will be described in detail below.

[0055] The air conditioning anti-condensation control method in this embodiment of the invention is applied to an air conditioning anti-condensation control device, which is installed in an air conditioner. The air conditioner includes one or more processors, a memory, and one or more application programs, wherein the one or more application programs are stored in the memory and configured to be executed by the processor to implement the air conditioning anti-condensation control method; the air conditioner can be an indoor unit, or an air conditioning system including an indoor unit.

[0056] like Figure 1 As shown, Figure 1 This is a schematic diagram of a scenario for an air conditioner anti-condensation control method according to an embodiment of this application. The air conditioner anti-condensation control scenario in this embodiment includes an air conditioner 100 (which integrates an air conditioner anti-condensation control device). The air conditioner 100 runs a computer-readable storage medium corresponding to the air conditioner anti-condensation control to execute the steps of the air conditioner anti-condensation control.

[0057] Understandable, Figure 1 The air conditioners in the scenario of the air conditioner anti-condensation control method shown, or the devices contained in the air conditioners, do not constitute a limitation on the embodiments of the present invention. That is, the number or type of air conditioners in the scenario of the air conditioner anti-condensation control method, or the number or type of devices contained in each air conditioner, do not affect the overall implementation of the technical solution in the embodiments of the present invention, and can all be considered as equivalent substitutions or derivatives of the technical solutions claimed in the embodiments of the present invention.

[0058] In this embodiment of the invention, the air conditioner 100 is mainly used for: acquiring the ambient temperature, inner pipe temperature, outer pipe temperature, and exhaust temperature corresponding to the internal environment of the air conditioner; predicting the target ambient temperature within a preset distance of the electronic control board in the air conditioner based on the ambient temperature, the inner pipe temperature, and the exhaust temperature; and adjusting the operating parameters of the air conditioner based on the outer pipe temperature and the temperature difference between the target ambient temperature and the preset dew point temperature to prevent condensation on the electronic control board.

[0059] Those skilled in the art will understand that Figure 1 The application environment shown is merely one application scenario of the solution in this application and does not constitute a limitation on the application scenario of the solution in this application. Other application environments may include those that are more specific to this application. Figure 1 The number of more or fewer air conditioners shown, or the air conditioner network connection relationship, for example Figure 1Only one air conditioner is shown in the diagram. It is understood that the scenario of the air conditioner anti-condensation control method may also include one or more other air conditioners, which are not specifically limited here. The air conditioner 100 may also include a memory for storing data, such as storing image information acquired by shooting.

[0060] Furthermore, in the scenario of the air conditioner anti-condensation control method of this application, the air conditioner 100 can be equipped with a display device, or the air conditioner 100 can be connected to an external display device 200 without a built-in display device. The display device 200 is used to output the results of the air conditioner anti-condensation control method execution. The air conditioner 100 can access the background database 300 (the background database can be in the local storage of the air conditioner, or it can be located in the cloud). The background database 300 stores information related to air conditioner anti-condensation control, such as the initial image in the background database 300, or pre-set filtering parameters.

[0061] It should be noted that, Figure 1 The schematic diagram of the air conditioning anti-condensation control method shown is merely an example. The scenarios of the air conditioning anti-condensation control method described in the embodiments of the present invention are for the purpose of more clearly illustrating the technical solutions of the embodiments of the present invention, and do not constitute a limitation on the technical solutions provided in the embodiments of the present invention.

[0062] Based on the scenario of the above-mentioned air conditioning anti-condensation control method, an embodiment of the air conditioning anti-condensation control method is proposed.

[0063] like Figure 2 The diagram shown is a flowchart of an embodiment of the air conditioning anti-condensation control method in this application. The air conditioning anti-condensation control method includes steps S201-S203:

[0064] S201. Obtain the ambient temperature, inner pipe temperature, outer pipe temperature and exhaust temperature corresponding to the internal environment of the air conditioner.

[0065] The ambient temperature refers to the ambient temperature of the environment corresponding to the air conditioner's control board, for example, the internal temperature of the base station air conditioner's enclosure.

[0066] The inner pipe temperature refers to the refrigerant pipe temperature corresponding to the indoor unit of the air conditioner.

[0067] The external pipe temperature refers to the refrigerant pipe temperature corresponding to the outdoor unit of the air conditioner.

[0068] Among them, exhaust temperature refers to the exhaust temperature of the air conditioner compressor.

[0069] It is understandable that ambient temperature, inner pipe temperature, outer pipe temperature, and exhaust temperature can be collected by temperature sensors installed at their respective locations.

[0070] Specifically, in one embodiment of this application, the air conditioning anti-condensation control method is applied to a base station air conditioner. When the base station air conditioner is detected to have run for a longer than a preset duration, the ambient temperature, inner pipe temperature, outer pipe temperature, and exhaust temperature corresponding to the internal environment of the air conditioner are obtained.

[0071] S202. Based on the ambient temperature, the inner pipe temperature, and the exhaust temperature, predict the target ambient temperature within a preset distance of the air conditioner's control board.

[0072] Specifically, after obtaining the ambient temperature, the inner pipe temperature, and the exhaust temperature, the air conditioner predicts the target ambient temperature within a preset distance of the air conditioner's control board based on these parameters. This application does not impose specific limitations on this prediction; an example is provided:

[0073] In one embodiment of this application, after obtaining the ambient temperature, the inner pipe temperature and the exhaust temperature, the air conditioner searches a preset mapping table to obtain the target ambient temperature corresponding to the ambient temperature, the inner pipe temperature and the exhaust temperature.

[0074] In another embodiment of this application, after obtaining the ambient temperature, the inner pipe temperature and the exhaust temperature, the air conditioner calculates the target ambient temperature corresponding to the ambient temperature, the inner pipe temperature and the exhaust temperature according to a preset calculation formula.

[0075] S203. Adjust the operating parameters of the air conditioner according to the temperature of the outer pipe and the temperature difference between the target ambient temperature and the preset dew point temperature to prevent condensation on the electronic control board.

[0076] The preset dew point temperature is a preset temperature threshold for the air conditioner circuit board where condensation may occur. It can be understood that the preset dew point temperature can be a general temperature or different temperatures can be set for different temperature difference ranges. This application does not make any specific limitations.

[0077] Specifically, after determining the target ambient temperature, the air conditioner calculates the temperature difference between the target ambient temperature and the preset dew point temperature, and adjusts the air conditioner operation in conjunction with the external pipe temperature. This application does not specifically limit the specific implementation method. For example, the air conditioner operation can be controlled by looking up a preset table to obtain the air conditioner operation parameters corresponding to the temperature difference and external pipe temperature, or by adjusting the air conditioner operation parameters using the temperature difference and external pipe temperature in conjunction with a preset analysis and control model to prevent condensation on the electronic control board.

[0078] It is understandable that by combining ambient temperature, inner pipe temperature, and exhaust temperature to predict the temperature near the electronic control board, and then combining this with the outer pipe temperature to adjust the air conditioning operating parameters, the ambient temperature, exhaust temperature, inner pipe temperature, and outer pipe temperature are affected, thereby adjusting the temperature near the electronic control board and achieving the purpose of preventing condensation on the electronic control board.

[0079] Furthermore, based on the above implementation scheme, this application also provides a specific implementation scheme for predicting the target ambient temperature, specifically including:

[0080] The ambient temperature, the inner pipe temperature, and the exhaust temperature are input into a preset calculation formula, and the target ambient temperature within a preset distance of the air conditioner's electronic control board is output.

[0081] The preset calculation formula is: T1=a1T2+a2T3+a3T4+β, where T1 is the target ambient temperature, T2 is the ambient temperature, T3 is the inner tube temperature, T4 is the exhaust temperature, and a1, a2, a3 and β are constants.

[0082] It is understandable that the condensation temperature near the indoor unit's control board, rather than the condensation temperature of the indoor unit itself, could easily lead to significant errors in estimating the condensation temperature under extreme conditions, such as low-temperature cooling or high-load defrosting. This solution uses experimental statistical methods to first record various operating conditions: the indoor ambient temperature, indoor pipe temperature, exhaust temperature, and the control board condensation temperature (measured by sensors during formula fitting; the control board condensation temperature is not required in actual operation) under high / low / cooling conditions. Then, a linear function difference fitting is used to derive the mathematical correspondence between the three indoor unit temperatures and the control board condensation temperature. This yields the preset calculation formula.

[0083] Further, see Figure 3 , Figure 3 This is a flowchart illustrating one implementation of the air conditioner anti-condensation control method provided in this application, specifically including steps S301-S303:

[0084] S301. Calculate the temperature difference between the target ambient temperature and the preset dew point temperature.

[0085] Specifically, after predicting the target ambient temperature within a preset distance of the electronic control board (i.e., the temperature near the electronic control board, where condensation is generally related to temperature changes near the electronic control board), the air conditioner calculates the temperature difference between the target ambient temperature and the preset dew point temperature.

[0086] S302. Based on the temperature range of the external pipe temperature, determine the control parameters, input the control parameters and the temperature difference value into a preset controller, and output the operating parameters of the air conditioner.

[0087] The control parameters are at least one of the proportional, derivative, and integral parameters of a preset controller, the preset controller includes a PI controller and / or a PID controller, and the operating parameters include the fan speed and / or the target valve opening.

[0088] Specifically, after obtaining the temperature of the outer pipe, the air conditioner determines the temperature range in which the outer pipe temperature is located, and further determines the corresponding control parameters based on the temperature range. The control parameters can be proportional parameters, derivative parameters, or integral parameters, or proportional parameters and integral parameters, or proportional parameters, integral parameters, and derivative parameters.

[0089] S303. Control the operation of the air conditioner according to its operating parameters.

[0090] Specifically, after acquiring the operating parameters of the air conditioner, the air conditioner controls its operation based on those operating parameters.

[0091] Specifically, based on the above-described implementation methods, this application also provides an implementation method for determining control parameters. In this implementation method, the preset controller includes a PI controller, and the operating parameters of the air conditioner include fan operating parameters. See also Figure 4 , Figure 4 A flowchart illustrating one implementation scheme for determining control parameters in the air conditioning anti-condensation control method provided in this application is shown, specifically including steps S401-S403:

[0092] S401. Based on the temperature range of the outer pipe temperature, determine the target PI control parameter and the fan adjustment rate corresponding to the target PI control parameter.

[0093] Specifically, after obtaining the external pipe temperature, the air conditioner determines the preset temperature range of the external pipe temperature, and further looks up the target table to determine the target PI control parameters and the fan adjustment rate corresponding to the target PI control parameters. The target table is shown below:

[0094]

[0095]

[0096] S402. Input the target PI control parameters and the temperature difference value into a preset PI controller, and output the target fan speed.

[0097] The target PI control parameters include the proportional parameter P and the integral parameter I.

[0098] For details, see Figure 5 After the air conditioner obtains the target PI control parameters, it updates the proportional parameter P and integral parameter I of the PI controller according to the proportional parameter P and integral parameter I, and inputs the temperature difference value as the input value into the PI controller to obtain the target fan speed. The target fan speed is then input into the corresponding control system (system) of the air conditioner to control the air conditioner fan speed adjustment.

[0099] S403. Execute the step of obtaining the ambient temperature, inner pipe temperature, outer pipe temperature and exhaust temperature corresponding to the internal environment of the air conditioner according to the fan adjustment rate, so as to update the target fan speed.

[0100] Specifically, after obtaining the target fan speed, the ambient temperature, inner pipe temperature, outer pipe temperature, and exhaust temperature corresponding to the internal environment of the air conditioner are further obtained according to the fan adjustment rate. Based on the newly obtained ambient temperature, inner pipe temperature, and exhaust temperature, the target ambient temperature within the preset distance of the air conditioner's control board is re-predicted. Based on the new outer pipe temperature and the temperature difference between the new target ambient temperature and the preset dew point temperature, a new target fan speed is determined, thereby updating the target fan speed and preventing condensation on the control board.

[0101] It is understood that this invention uses an intelligent fuzzy control system with stepless speed regulation and single closed-loop control (PI control) to control the ventilation volume (fan speed) of the inner unit (inside the base station air conditioner, or the indoor unit corresponding to a regular air conditioner). It analyzes how to obtain the temperature near the inner control unit by measuring the inner pipe temperature, inner ambient temperature, and exhaust temperature. Then, it calculates the difference between this temperature and the standard condensation temperature measured in the laboratory, and continuously adjusts the fan speed to influence the inner ambient temperature, exhaust temperature, and pipe temperature. This ensures that the temperature near the control unit and the condensation temperature differ by a preset temperature difference or more, thus achieving the aforementioned purpose of preventing condensation. The fan speed adjustment rate can be determined based on the fan adjustment rate corresponding to the ambient temperature of the outer pipe.

[0102] Furthermore, based on the listed implementation scheme, this application also provides another implementation scheme for determining the operating parameters of an air conditioner, wherein the preset controller includes a PID controller, and the operating parameters of the air conditioner include the opening degree of the compressor's solenoid valve; the step of determining control parameters according to the temperature range of the external pipe temperature, inputting the control parameters and the temperature difference value into the preset controller, and outputting the operating parameters of the air conditioner specifically includes the following steps:

[0103] (1) Determine the target PID control parameters based on the temperature range of the outer tube temperature;

[0104] (2) Input the target PID control parameters and the temperature difference value into a preset PID controller, and output the target valve opening.

[0105] The target PID control parameters include proportional parameter P, integral parameter I, and derivative parameter D.

[0106] For details, see Figure 6 After acquiring the target PI control parameters, the air conditioner updates the proportional parameter P, integral parameter I, and derivative parameter D of the PID controller according to the proportional parameter P, integral parameter I, and derivative parameter D. The temperature difference value is then input to the PI controller to obtain the target valve opening. This target valve opening is then input to the corresponding control system (system) of the air conditioner to adjust the opening of the air conditioner's solenoid valve. It is understood that the solenoid valve opening can also be updated according to a preset adjustment frequency or fan adjustment rate, or the opening adjustment frequency corresponding to the external pipe temperature (i.e., the update frequency of the target valve opening). The update method is described in the above implementation scheme for fan speed updating.

[0107] Furthermore, based on the above implementation scheme, this application also provides an implementation scheme for correcting the target valve opening degree, specifically including the following steps:

[0108] (1) Determine the target PID control parameters based on the temperature range of the outer tube temperature;

[0109] (2) Input the target PID control parameters and the temperature difference value into a preset PID controller, and output the target valve opening.

[0110] (3) Find the preset relationship table between temperature range and opening compensation value, and obtain the target opening compensation value corresponding to the ambient temperature and the external ambient temperature corresponding to the external environment of the air conditioner.

[0111] (4) Correct the target valve opening based on the target opening compensation value, and control the air conditioner operation based on the corrected target valve opening.

[0112] For details, please refer to the preset relationship table between temperature ranges and opening compensation values ​​as follows:

[0113]

[0114] Specifically, the air conditioner obtains the ambient temperature corresponding to the internal environment (inside the base station air conditioner casing) and the external ambient temperature corresponding to the external environment (outside the base station air conditioner casing), and obtains the temperature range corresponding to the ambient temperature and the target opening compensation value corresponding to the temperature range corresponding to the external ambient temperature according to a preset relationship table. The target opening compensation value is used to correct the target valve opening, and the air conditioner is controlled to operate according to the corrected target valve opening.

[0115] Furthermore, based on the above implementation scheme, this application also provides a specific implementation scheme for obtaining the ambient temperature, inner pipe temperature, outer pipe temperature, and exhaust temperature corresponding to the internal environment of the air conditioner, including the following steps:

[0116] (1) Collect the initial ambient temperature, initial inner pipe temperature, initial outer pipe temperature and initial exhaust temperature of the environment corresponding to the air conditioner's electronic control board within a preset time period.

[0117] (2) The initial ambient temperature, initial inner tube temperature, initial outer tube temperature and initial exhaust temperature are filtered respectively;

[0118] (3) The initial ambient temperature, initial inner tube temperature, initial outer tube temperature and initial exhaust temperature after filtering are averaged to obtain the ambient temperature, inner tube temperature, outer tube temperature and exhaust temperature.

[0119] Specifically, sensors installed at corresponding locations collect the initial ambient temperature, initial inner pipe temperature, initial outer pipe temperature, and initial exhaust temperature of the air conditioner's control board within a preset time period.

This ensures the accuracy of the temperature data collection.

[0120] Existing air conditioners cannot directly reflect changes in humidity inside the unit by judging changes in indoor humidity, and increase humidity penetration. In contrast, the method proposed in this invention can avoid increased costs and the irrationality of simply increasing the speed of the indoor unit's fan to achieve the goal of preventing condensation. It also improves the intelligence of base station air conditioners and the research on new technologies for base station air conditioner controllers.

[0121] This application provides an air conditioning anti-condensation control method. It acquires the ambient temperature, inner pipe temperature, outer pipe temperature, and exhaust temperature corresponding to the internal environment of the air conditioner. Based on the ambient temperature, inner pipe temperature, and exhaust temperature, it predicts the target ambient temperature within a preset distance of the air conditioner's control board. Based on the outer pipe temperature and the temperature difference between the target ambient temperature and the preset dew point temperature, it adjusts the air conditioner's operating parameters to prevent condensation on the control board. It is understood that condensation on the control board occurs when the control board heats up and encounters nearby cold air, causing condensation. This method collects the ambient temperature, inner pipe temperature, and exhaust temperature during air conditioner operation, and combines these to predict the actual ambient temperature (target ambient temperature) within a preset distance of the control board. Furthermore, it adjusts the air conditioner's operating parameters based on the outer pipe temperature and the difference between the actual ambient temperature and the dew point temperature, thereby preventing condensation on the control board, avoiding frost formation, and improving the operational stability of the air conditioner's control board.
