Description

Technical Field

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

[0002] During operation, air conditioners typically use a temperature sensor installed at the return air vent to detect the return air temperature, which characterizes the indoor temperature, in order to control the air conditioner's operation and regulate the indoor temperature. However, the return air vent, corresponding to the indoor unit, is usually located at a high position. During operation, due to the density difference between hot and cold air, the hot air continuously rises, causing it to accumulate at the high-positioned return air vent. This results in a significant difference between the detected return air temperature and the actual indoor temperature, thus reducing the accuracy of the air conditioner's control. Summary of the Invention

[0003] This application provides an air conditioning control method, device, air conditioner, and storage medium, aiming to solve the problem in the prior art where the difference between the detected return air temperature and the actual indoor temperature is large, reducing the control accuracy of the air conditioner.

[0004] In a first aspect, this application provides an air conditioning control method, comprising:

[0005] In response to the heating operation command of the air conditioner, the first return air temperature, the first condensing temperature and the first outdoor ambient temperature of the air conditioner are obtained;

[0006] Based on the first return air temperature, the first condensing temperature, and the first outdoor ambient temperature, determine the first heat load corresponding to at least two time points, and determine the first theoretical temperature change parameter based on the change information of the first heat load;

[0007] The air conditioner is controlled to adjust its operating state based on the relationship between the first theoretical temperature change parameter and the first temperature change parameter of the first return air temperature.

[0008] In one possible implementation of this application, after determining the first theoretical temperature change parameter based on the first heat load change information, the method further includes:

[0009] The first theoretical temperature change parameter is corrected according to the preset change correction parameter;

[0010] Based on the relationship between the corrected first theoretical temperature change parameter and the first temperature change parameter of the first return air temperature, the air conditioner is controlled to adjust its operating state.

[0011] The preset change correction parameter is determined according to the following steps:

[0012] The second return air temperature, the second condensing temperature, and the second outdoor ambient temperature are obtained when the air conditioner is running in cooling mode.

[0013] The second heat load of the air conditioner is calculated based on the second return air temperature, the second condensing temperature, and the second outdoor ambient temperature, and the second theoretical temperature change parameter is determined based on the change information of the second heat load.

[0014] The preset change correction parameter is determined based on the second theoretical temperature change parameter and the second temperature change parameter of the second return air temperature.

[0015] In one possible implementation of this application, the first condensation temperature includes the inlet temperature and outlet temperature of the condenser.

[0019] The first heat load corresponding to the time point is determined based on the heat load correction coefficient, the temperature difference between the inlet temperature and the outlet temperature.

[0020] In one possible implementation of this application, determining the first heat load corresponding to the time point based on the heat load correction coefficient, the temperature difference between the inlet temperature and the outlet temperature includes:

[0021] The heat load correction coefficient, the inlet temperature, and the outlet temperature are input into a preset heat load calculation formula to obtain the first heat load corresponding to the time point;

[0022] The formula for calculating the heat load is as follows:

[0023] Wherein, Q is the first heat load, c is the heat load correction coefficient, T3B is the inlet temperature, T3A is the outlet temperature, and L is the preset system flow parameter corresponding to the air conditioner.

[0024] In one possible implementation of this application, controlling the air conditioner to adjust its operating state based on the magnitude relationship between the modified first theoretical temperature change parameter and the first temperature change parameter of the first return air temperature includes:

[0025] Calculate the first temperature change parameter based on the first return air temperature obtained within a preset time period;

[0026] If the first temperature change parameter is greater than the first theoretical temperature change parameter, the air conditioner is controlled to exit the preset temperature-reaching shutdown control logic, and the internal fan speed of the air conditioner is controlled to increase.

[0027] In one possible implementation of this application, after controlling the air conditioner to exit the preset temperature-reaching shutdown control logic and controlling the indoor fan speed of the air conditioner to increase, the method further includes:

[0028] Reacquire the first return air temperature and calculate the new temperature change parameters based on the reacquired first return air temperature;

[0029] If the new temperature change parameter is less than or equal to the first theoretical temperature change parameter, the air conditioner is controlled to re-enter the preset temperature-reaching shutdown control logic, and the internal fan speed of the air conditioner is controlled to resume.

[0030] In one possible implementation of this application, the step of responding to the heating operation command of the air conditioner and obtaining the first return air temperature, the first condensing temperature, and the first outdoor ambient temperature of the air conditioner includes:

[0031] In response to the heating operation command of the air conditioner, the indoor fan of the air conditioner is controlled to run at maximum speed for a preset time, and the first return air temperature and the first outdoor ambient temperature at each time point are obtained according to the preset acquisition frequency.

[0032] When the difference between the first return air temperature and the set temperature corresponding to the heating operation command is less than a preset temperature difference threshold, the first condensing temperature of the air conditioner at each time point is obtained.

[0033] Secondly, this application provides an air conditioning control device, the device comprising:

[0034] The response acquisition module is used to respond to the heating operation command of the air conditioner and acquire the first return air temperature, the first condensing temperature and the first outdoor ambient temperature of the air conditioner.

[0035] The determination module is used to determine the first heat load corresponding to at least two time points based on the first return air temperature, the first condensing temperature and the first outdoor ambient temperature, and to determine the first theoretical temperature change parameter based on the change information of the first heat load.

[0036] The control module is used to control the air conditioner to adjust its operating state based on the relationship between the first theoretical temperature change parameter and the first temperature change parameter of the first return air temperature.

[0037] Thirdly, this application provides an air conditioner, the air conditioner comprising:

[0038] One or more processors;

[0039] Memory; and

[0040] One or more applications, wherein the one or more applications are stored in the memory and configured to be executed by the processor to implement the steps in any of the air conditioning control methods described above.

[0041] Fourthly, this application provides a computer-readable storage medium having a computer program stored thereon, the computer program being loaded by a processor to perform the steps in any of the air conditioning control methods described herein.

[0042] This application provides an air conditioning control method, device, air conditioner, and storage medium. By responding to the air conditioner's heating operation command, it acquires the first return air temperature, first condensing temperature, and first outdoor ambient temperature of the air conditioner. Based on these three temperatures, it determines a first heat load corresponding to at least two time points, and determines a first theoretical temperature change parameter based on the change information of the first heat load. Based on the relationship between the first theoretical temperature change parameter and the first temperature change parameter of the first return air temperature, it controls the air conditioner to adjust its operating state. This solution calculates the first heat load of the air conditioner during heating operation and determines the theoretical change parameter corresponding to the indoor ambient temperature based on the change. Furthermore, it compares the actual return air temperature (i.e., the first return air temperature, representing the indoor ambient temperature) with the theoretical change parameter. Specifically, it determines whether the air conditioner's detected return air temperature accurately represents the actual indoor ambient temperature, and whether the deviation between the return air temperature and the actual ambient temperature is large. This allows for the determination of whether heat accumulation occurs at the return air vent, enabling adaptive adjustments to the air conditioner. This avoids the accumulation of hot air at the return air vent affecting indoor temperature detection during heating operation, thus improving the accuracy of air conditioning control.

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.

[0056] This application provides an air conditioning control method, device, air conditioner, and computer-readable storage medium (hereinafter referred to as storage medium), which will be described in detail below.

[0057] The air conditioning control method in this embodiment of the invention is applied to an air conditioning control device, which is installed in an air conditioner. The air conditioner is equipped with one or more processors, a memory, and one or more application programs. The one or more application programs are stored in the memory and configured to be executed by the processor to implement the air conditioning control method. The air conditioner can be a system, such as an air conditioning system including an indoor unit and an outdoor unit, or a terminal, such as a window air conditioner.

[0058] like Figure 1 As shown, Figure 1 This is a schematic diagram of a scenario for an air conditioning control method according to an embodiment of this application. The air conditioning control scenario in this embodiment includes an air conditioner 100 (which integrates an air conditioning control device). The air conditioner 100 runs a computer-readable storage medium corresponding to the air conditioning control to execute the steps of the air conditioning control.

[0059] Understandable, Figure 1 The air conditioners in the scenario of the air conditioning 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 conditioning 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.

[0060] In this embodiment of the invention, the air conditioner 100 is mainly used for: responding to the air conditioner's heating operation command, acquiring the air conditioner's first return air temperature, first condensing temperature, and first outdoor ambient temperature; determining a first heat load corresponding to at least two time points based on the first return air temperature, the first condensing temperature, and the first outdoor ambient temperature, and determining a first theoretical temperature change parameter based on the change information of the first heat load; and controlling the air conditioner to adjust its operating state based on the magnitude relationship between the first theoretical temperature change parameter and the first temperature change parameter of the first return air temperature.

[0061] 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.

[0062] Furthermore, in the scenario of the air conditioning control method of this application, the air conditioner 100 may be equipped with a display device, or the air conditioner 100 may not have a display device but may communicate with an external display device 200. The display device 200 is used to output the results of the air conditioning control method executed in the air conditioner. The air conditioner 100 can access the background database 300 (the background database may be in the local storage of the air conditioner or it may be located in the cloud). The background database 300 stores information related to air conditioning control, such as the initial image in the background database 300 or pre-set filtering parameters.

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

[0064] Based on the scenarios described above for air conditioning control methods, an embodiment of the air conditioning control method is proposed.

[0065] like Figure 2 The diagram shown is a flowchart of an embodiment of the air conditioning control method in this application. The air conditioning control method includes steps S201-S203:

[0066] S201. Responding to the heating operation command of the air conditioner, obtain the first return air temperature, the first condensing temperature and the first outdoor ambient temperature of the air conditioner.

[0067] The first return air temperature, that is, the temperature of the return air vent detected by the air conditioner during heating operation, can be obtained by installing a temperature detection device at the air conditioner return air vent.

[0068] The first condensing temperature includes the temperature of the refrigerant in the air conditioner before and after passing through the condenser for heat exchange. For example, the first condensing temperature can be obtained by detecting the inlet pipe temperature and the outlet pipe temperature by a temperature detection device installed at the condenser inlet and the condenser outlet, or by detecting the inlet pipe temperature of the condenser by a temperature detection device installed at any position between the compressor outlet and the condenser inlet. This application does not make any specific limitations.

[0069] The first outdoor ambient temperature refers to the outdoor ambient temperature of the environment in which the outdoor unit of the air conditioner is installed. For example, the first outdoor ambient temperature can be obtained by a temperature detection device installed on the outdoor unit of the air conditioner.

[0070] It is understood that the first return air temperature, the first condensing temperature, and the first outdoor ambient temperature can be obtained according to a preset temperature acquisition frequency. That is, the first return air temperature, the first condensing temperature, and the first outdoor ambient temperature are not limited to a certain temperature detected at a certain moment, and can be updated according to the heating operation process of the air conditioner.

[0071] S202. Based on the first return air temperature, the first condensing temperature and the first outdoor ambient temperature, determine the first heat load corresponding to at least two time points, and determine the first theoretical temperature change parameter based on the change information of the first heat load.

[0072] The first heat load is used to characterize the heat exchange of the indoor environment corresponding to the operation of the air conditioner. However, the change in indoor temperature during the heating operation of the air conditioner is affected by the outdoor environment, which means that the change in indoor temperature cannot purely characterize the change in indoor temperature. Therefore, when calculating the first heat load corresponding to the indoor temperature, the first return air temperature, the first condensing temperature and the first outdoor temperature are combined to obtain the first heat load.

[0073] It is understood that the first heat load may include heat loads at multiple time points. It is also understood that the first heat load corresponding to each time point is determined based on the first return air temperature, the first condensing temperature, and the first outdoor ambient temperature at that time point. The specific calculation is not specifically limited in this application; an example is provided:

[0074] In one embodiment of this application, the air conditioner is equipped with a pre-trained load calculation model. The air conditioner inputs the first return air temperature, the first condensing temperature and the first outdoor ambient temperature of the air conditioner at a certain time point into the load calculation model to calculate the first heat load corresponding to that time point. Furthermore, based on the first return air temperature, the first condensing temperature and the first outdoor ambient temperature corresponding to multiple time points, the first heat load corresponding to multiple time points is determined.

[0075] In another embodiment of this application, the first return air temperature, the first condensing temperature and the first outdoor ambient temperature of the air conditioner at a certain time point can be input into a preset calculation formula to calculate the first heat load at a certain time point.

[0076] Specifically, one type of air conditioner in this application collects the first condensing temperature, or the first condensing temperature and the first return air temperature, at different time points during heating operation to calculate the first heat load at the corresponding time point, and determines the temperature change parameter within the preset time period based on each heat load at different time points within the preset time period. That is, it can be understood that in some embodiments, the theoretical temperature change parameter is continuously updated as the heating operation time is updated, so as to be compared with the first temperature change parameter of the first return air temperature corresponding to the heating operation time.

[0077] The first theoretical temperature change parameter is a parameter used to characterize the change information of the corresponding first heat load and the theoretical change information of the indoor ambient temperature. For example, the first theoretical temperature change parameter can be the theoretical temperature change rate, the theoretical temperature change difference, etc.

[0078] It is understood that, based on the change information of the first heat load, the first theoretical temperature change parameter can be determined by looking up a preset correspondence or by using a preset calculation formula. For example, in one embodiment of this application, after determining the first heat load, the air conditioner inputs the first heat load into a preset calculation formula to calculate the first theoretical temperature corresponding to the first heat load, and determines the first theoretical temperature change parameter by using the first theoretical temperature obtained within a preset time period.

[0079] Furthermore, it can be understood that in some other embodiments of this application, the first theoretical temperature change parameter corresponding to the temperature change of the first condensing temperature during the heating stable mode within a preset time period can also be used as the first theoretical temperature change parameter in the heating stable mode to evaluate the first temperature change parameter of the first return air temperature at each time point in the heating stable mode.

[0080] S203. Based on the relationship between the first theoretical temperature change parameter and the first temperature change parameter of the first return air temperature, control the air conditioner to adjust its operating state.

[0081] The first temperature change parameter of the first return air temperature is used to characterize the temperature change information of the first return air temperature. For example, the first temperature change parameter, corresponding to the first theoretical temperature change parameter, can be the amount of temperature change (difference) or the rate of temperature change.

[0082] Specifically, in one embodiment of this application, the air conditioner responds to the heating operation of the air conditioner by controlling the activation of the heating mode, acquiring the first return air temperature, the first condensing temperature, and the first outdoor ambient temperature of the air conditioner, calculating the first heat load corresponding to each time point, and finding the preset correspondence between the preset heat load and temperature to obtain the first theoretical temperature corresponding to the first heat load. Based on the historical first theoretical temperature and the first theoretical temperature acquired within a preset time period, the corresponding first theoretical temperature change rate (first theoretical temperature change parameter) is calculated; and the first temperature change rate (first temperature change parameter) corresponding to the first return air temperature within the preset time period is calculated. The first temperature change rate is compared with the first theoretical temperature change rate, and the magnitude is determined based on the magnitude relationship to determine whether heat accumulation occurs at the return air vent in the heating mode.

[0083] For example, if the comparison shows that the first theoretical temperature change parameter is greater than the first temperature change parameter of the first return air temperature, it indicates that the temperature rise rate at the return air vent is slow and the hot air has not accumulated at the return air vent, i.e., no heat accumulation has occurred. Conversely, it is determined that heat accumulation is occurring, and the air conditioner is adjusted accordingly. For example, the indoor unit fan speed of the air conditioner is increased to accelerate indoor airflow circulation and reduce heat accumulation.

[0084] Specifically, in one embodiment of this application, the air conditioning control method is applied to an air conditioning control device, which is installed in the air conditioner. The user can input the air conditioner's heating command through a remote control or mobile terminal that communicates with the air conditioner. After receiving the air conditioner's heating operation command, the air conditioner controls the air conditioner to respond to the heating operation and collects the first return air temperature, the first condensing temperature, and the first outdoor ambient temperature of the air conditioner through a temperature sensor installed at the corresponding position of the air conditioner.

[0085] Based on the above implementation scheme, this application also provides a method for obtaining temperature, specifically including the following steps:

[0086] (1) Responding to the heating operation command of the air conditioner, the indoor fan of the air conditioner is controlled to run at the maximum speed for a preset time, and the first return air temperature and the first outdoor ambient temperature at each time point are obtained according to the preset acquisition frequency.

[0087] (2) When the difference between the first return air temperature and the set temperature corresponding to the heating operation command is less than the preset temperature difference threshold, the first condensing temperature of the air conditioner at each time point is obtained.

[0088] It is understood that the first outdoor ambient temperature can be collected only once within a preset time period, or it can be collected in real time at a preset collection frequency. The collection frequency of the first condensing temperature can be the same as that of the first return air temperature, that is, the time point corresponding to the first return air temperature and the time point corresponding to the first condensing temperature are the same; or the collection frequencies can be different, and the time points are aligned after collection. This application does not limit the specifics.

[0089] It is understood that in some embodiments of this application, the initial acquisition time of the first return air temperature, the first condensing temperature, and the first outdoor ambient temperature can be limited to ensure the accuracy of the acquired first return air temperature, first condensing temperature, and first outdoor ambient temperature. For example, in some embodiments of this application, after the air conditioning system starts operating in heating mode, the indoor unit of the air conditioner operates at maximum fan speed for 2 minutes (preset duration) before acquiring the current first outdoor ambient temperature T4o and the first return air temperature T4i. After detecting that the system has entered a stable heating operation mode, the current condenser outlet pipe temperature T3A and condenser inlet pipe temperature T3B are acquired. Regarding the condensing temperature, it can be understood that the system can determine whether it has entered the stable heating operation mode based on the duration or the compressor frequency. For example, when the difference between the first return air temperature and the set temperature is less than the preset temperature difference threshold, it indicates that the air conditioning system has entered the stable heating operation mode. Alternatively, the air conditioning system can enter the stable heating operation mode after a second preset heating operation duration. That is, after the air conditioning heating operation duration reaches the preset time, the current condenser outlet pipe temperature T3A and condenser inlet pipe temperature T3B are collected. Or, after the air conditioning compressor speed stabilizes, it is determined that the air conditioning system has entered the stable heating operation mode, and the current condenser outlet pipe temperature T3A and condenser inlet pipe temperature T3B are collected.

[0090] Specifically, in the implementation scheme of this application, when the unit is in heating mode, the indoor side, being the heating side, experiences significant temperature variations. Therefore, this invention uses the relatively stable outdoor side as the calculation object, with the condenser's inlet and outlet pipe temperatures as the main calculation parameters. A correction coefficient is calculated using the outdoor ambient temperature, indoor ambient temperature, and set temperature to determine the current heat load of the system. This is used as the indoor and outdoor heat load, thus obtaining the first heat load and enhancing the calculation accuracy of the first heat load. Simultaneously, the first return air temperature is monitored in real time as the indoor ambient temperature. The rate of change of the first ambient temperature corresponding to the first return air temperature is compared with the rate of change of the first theoretical temperature corresponding to the first heat load. If the former is significantly greater than the latter, it can be preliminarily determined that heat accumulation has occurred in the system. This approach avoids the low air conditioning control accuracy caused by controlling the air conditioner based on the return air temperature in related technologies, and eliminates the need for any additional temperature detection components to monitor heat accumulation, improving the accuracy of indoor temperature detection and thus enhancing the air conditioning control accuracy.

[0091] Furthermore, based on the above implementation plan, see [link to relevant documentation]. Figure 3 , Figure 3 This is a schematic flowchart of another embodiment of the air conditioning control method provided in this application, specifically including steps S301-S304:

[0092] S301. Responding to the heating operation command of the air conditioner, obtain the first return air temperature, the first condensing temperature and the first outdoor ambient temperature of the air conditioner.

[0093] S302. Based on the first return air temperature, the first condensing temperature and the first outdoor ambient temperature, determine the first heat load corresponding to at least two time points, and determine the first theoretical temperature change parameter based on the change information of the first heat load.

[0094] The specific implementation methods of steps S301-S302 are described in any of the above implementation schemes.

[0095] S303. Correct the first theoretical temperature change parameter according to the preset change correction parameter.

[0096] It is understandable that, due to the diverse installation environments of air conditioners, there will always be some discrepancy between the actual installation environment and the standard heat exchange volume. To reduce the impact of this factor, this invention will perform a calibration in cooling mode during the system debugging phase. Since cold air automatically dissipates downwards, heat accumulation is not likely to occur at the air conditioner's return air vent. Therefore, in cooling mode, the theoretical temperature change rate is calculated based on the standard volume, and then compared with the actual temperature change rate to obtain an installation environment correction coefficient. This coefficient serves as a preset change correction parameter, used to correct the first theoretical temperature change parameter calculated in heating mode, reducing the error of the first theoretical temperature change parameter and thus improving its accuracy.

[0097] Specifically, in one embodiment of this application, the preset change correction parameter is determined according to the following steps:

[0098] (1) Obtain the second return air temperature, the second condensing temperature and the second outdoor ambient temperature of the air conditioner when it is running in cooling mode;

[0099] (2) Calculate the second heat load of the air conditioner based on the second return air temperature, the second condensing temperature and the second outdoor ambient temperature, and determine the second theoretical temperature change parameter based on the change information of the second heat load;

[0100] (3) Determine the preset change correction parameter based on the second theoretical temperature change parameter and the second temperature change parameter of the second return air temperature.

[0101] Specifically, in one embodiment of this application, the determination of preset change correction parameters is applied in the scenario of the air conditioner's first power-on cooling operation, controlling the air conditioner system to enter calibration mode. This includes:

[0102] (a) In cooling mode, the current outdoor ambient temperature T4o is collected as the second outdoor ambient temperature, and the second return air temperature is collected as the indoor ambient temperature T4i. Furthermore, the set temperature Ts corresponding to the air conditioning cooling is collected, and then the cooling heat load correction coefficient a is calculated. The calculation formula is as follows:

[0103] ;

[0104] Wherein, K is an empirical coefficient, which is derived from experimental data statistics for a specific model.

[0105] (b) When the compressor frequency remains constant within 1 minute, it indicates that the system has entered a stable operating phase. The current [compressor discharge temperature TP] and [condenser outlet pipe temperature T3A] are collected as the second condensing temperature. Combined with the heat load correction factor a, the current heat load of the system can be calculated. See the specific formula:

[0106] ;

[0107] Where L is a preset coefficient for a specific model, which includes parameters such as system refrigerant quantity and flow rate.

[0108] (c) For indoor units of different capacities, the temperature change rate under theoretical conditions can be calculated based on their preset [rated capacity], and used as the second theoretical temperature change parameter m;

[0109] (d) Furthermore, during the 10-minute cooling operation, the second return air temperature is collected every 1 minute as the [indoor ambient temperature T4i], and the current actual [indoor temperature change rate n] is calculated as the second temperature change parameter;

[0110] (5) Further, based on the calculation formula, the system's installation environment correction coefficient b is calculated and stored as a preset change correction parameter. The calculation formula is as follows:

[0111]

[0112] Where J is an empirical coefficient for the rated capacity of different models.

[0113] Specifically, this application does not limit the implementation scheme of correcting the first theoretical temperature change parameter according to the preset change correction parameter. It can be addition, subtraction, multiplication, etc. For example, in one embodiment of this application, the first theoretical temperature change parameter is x, then the first theoretical temperature change parameter is corrected according to the formula b×x.

[0114] S304. Based on the relationship between the corrected first theoretical temperature change parameter and the first temperature change parameter of the first return air temperature, control the air conditioner to adjust its operating state.

[0115] Specifically, after obtaining the corrected first theoretical temperature change parameter, the corrected first theoretical temperature change is compared with the first temperature change parameter of the first return air temperature. For example, the first temperature change rate y of the first return air temperature is calculated as the first temperature change parameter. Furthermore, the relationship between y and the corrected first theoretical temperature change parameter b×x is compared. If y > b×x, it is determined that heat accumulation has occurred in the current environment, and the system enters the heat accumulation control mode; if y ≤ b×x, it is determined that no heat accumulation has occurred, and the unit operates normally.

[0116] It is understandable that when the heat concentration control mode is detected, the corresponding preset control logic is invoked. For example, the preset control logic for heat concentration control is to increase the indoor fan speed or switch to the air swing mode.

[0117] It is understood that the preset change correction parameters can be updated and optimized according to the actual situation in accordance with the above implementation scheme.

[0118] Specifically, in this implementation plan, considering the diverse installation environments of air conditioners, in order to reduce the impact of the air conditioning environment, an installation environment correction coefficient is calculated as a preset change correction parameter. This parameter is used to correct the first theoretical temperature change parameter calculated in heating mode, thereby reducing the error of the first theoretical temperature change parameter and improving its accuracy.

[0119] Furthermore, based on the above implementation plan, see [link to relevant documentation]. Figure 4 , Figure 4 This is a flowchart illustrating one implementation scheme of the air conditioning control method provided in this application, which determines the first heat load at any given time point. In this implementation scheme, the condensing temperature includes the inlet and outlet temperatures of the condenser. Steps S401-S402 are executed for the first return air temperature, the first condensing temperature, and the first outdoor ambient temperature at any given time point.

[0120] S401. Determine the heat load correction coefficient based on the first temperature difference between the first return air temperature and the first outdoor ambient temperature, and the second temperature difference between the first return air temperature and the target temperature corresponding to the heating operation.

[0121] Specifically, in one embodiment of this application, the system activates the heating mode, and the indoor unit of the air conditioner runs at its maximum fan speed for 2 minutes by default. It collects the [first outdoor ambient temperature T4o], the [first return air temperature] as the [indoor ambient temperature T4i], and the [set temperature Ts] corresponding to the air conditioner's heating mode. Then, it calculates the heating load correction coefficient c. The formula for calculating the heat load correction coefficient is as follows:

[0122] ;

[0123] S402. Determine the first heat load corresponding to the time point based on the heat load correction coefficient, the temperature difference between the inlet temperature and the outlet temperature.

[0124] For example, in one embodiment of this application, the temperature difference between the inlet temperature and the outlet temperature is calculated, and the first heat load corresponding to the temperature difference and the heat load correction factor is found according to the temperature difference, the heat load correction factor and the mapping table corresponding to the heat load.

[0125] Furthermore, in some other embodiments of this application, the first heat load of the air conditioner is determined based on the heat load correction coefficient, the temperature difference between the inlet temperature and the outlet temperature, specifically including the following steps:

[0126] The first heat load is obtained by inputting the heat load correction coefficient, the inlet temperature, and the outlet temperature into a preset heat load calculation formula;

[0127] The formula for calculating the heat load is as follows:

[0128]

[0129] Wherein, Q is the first heat load, c is the heat load correction coefficient, T3B is the inlet temperature, T3A is the outlet temperature, and L is the preset system flow parameter corresponding to the air conditioner.

[0130] It is understandable that if the input is the heat load correction coefficient, the inlet temperature, and the outlet temperature at a certain point in time, then the output is the first heat load at that point in time.

[0131] Furthermore, based on the above implementation plan, see [link to relevant documentation]. Figure 5 , Figure 5 This is a flowchart illustrating one embodiment of the air conditioning control method provided in this application, which involves adjusting the air conditioner, including steps S501-S502:

[0132] S501. Calculate the first temperature change parameter based on the first return air temperatures obtained within a preset time period.

[0133] Specifically, during the operation of the air conditioner, the air conditioner acquires the first return air temperature within a preset time period and calculates the first temperature change parameter. For example, during 20 minutes of heating operation, the first return air temperature is collected every 1 minute to obtain 20 first return air temperatures. Then, the temperature change rate of the first return air temperature is calculated to obtain the indoor temperature change rate within 20 minutes.

[0134] S502. If the first temperature change parameter is greater than the first theoretical temperature change parameter, then control the air conditioner to exit the preset temperature-reaching shutdown control logic and control the speed of the air conditioner's internal fan to increase.

[0135] Specifically, if the first temperature change parameter is greater than the first theoretical temperature change parameter, it indicates that heat accumulation is occurring. In this case, the air conditioner exits the preset temperature-reaching shutdown control logic, meaning the air conditioner will not stop when the temperature is reached. At the same time, the speed of the air conditioner's indoor fan is increased to enhance indoor air circulation, increase indoor air heat exchange, thereby reducing the indoor temperature difference and preventing heat accumulation at the return air vent.

[0136] Furthermore, in one embodiment of this application, the air conditioner responds to the heating operation command of the air conditioner, acquires the first return air temperature, the first condensing temperature, and the first outdoor ambient temperature of the air conditioner; calculates the first heat load of the air conditioner based on the first return air temperature, the first condensing temperature, and the first outdoor ambient temperature, and determines the first theoretical temperature change parameter based on the change information of the first heat load; calculates the first temperature change parameter based on each of the first return air temperatures acquired within a preset time period; if the first temperature change parameter is greater than the first theoretical temperature change parameter, the air conditioner is controlled to exit the preset temperature-reaching shutdown control logic, and the speed of the air conditioner's indoor fan is controlled to increase.

[0137] Furthermore, based on the above implementation plan, see [link to relevant documentation]. Figure 6 , Figure 6 This is a schematic flowchart of another embodiment of the air conditioning control method provided in this application, including steps S601-S607:

[0138] S601. Responding to the heating operation command of the air conditioner, obtain the first return air temperature, the first condensing temperature and the first outdoor ambient temperature of the air conditioner;

[0139] S602. Based on the first return air temperature, the first condensing temperature and the first outdoor ambient temperature, determine the first heat load corresponding to at least two time points, and determine the first theoretical temperature change parameter based on the change information of the first heat load.

[0140] S603. Correct the first theoretical temperature change parameter according to the preset change correction parameter;

[0141] S604. Calculate the first temperature change parameter based on the first return air temperature obtained within the preset time period;

[0142] S605. If the first temperature change parameter is greater than the corrected first theoretical temperature change parameter, then control the air conditioner to exit the preset temperature-reaching shutdown control logic and control the speed of the air conditioner's internal fan to increase.

[0143] The specific implementation methods of steps S601-S605 are described in any of the above implementation schemes.

[0144] S606. Reacquire the first return air temperature and calculate the new temperature change parameters based on the reacquired first return air temperature.

[0145] Specifically, after controlling the air conditioner to exit the preset temperature-reaching shutdown control logic and controlling the speed of the air conditioner's indoor fan to increase, the first return air temperature is reacquired, and a new temperature change rate is calculated based on the reacquired first return air temperature.

[0146] S607. If the new temperature change parameter is less than or equal to the first theoretical temperature change parameter, control the air conditioner to re-enter the preset temperature-reaching shutdown control logic and control the internal fan speed of the air conditioner to resume.

[0147] Furthermore, the recalculated new temperature change rate is compared with the first theoretical temperature change parameter. If the new temperature change parameter is less than or equal to the first theoretical temperature change parameter, it indicates that the heat accumulation at the return air vent has been eliminated. In this case, the internal fan speed of the air conditioner is restored, and the air conditioner is controlled to return to the temperature-reaching shutdown control logic. If the recalculated new temperature change parameter is greater than the first theoretical temperature change parameter, the first return air temperature is re-acquired, and the new temperature change rate is recalculated until the new temperature change parameter is less than or equal to the first theoretical temperature change parameter.

[0148] It is understood that in some embodiments of this application, if the new temperature change parameter is less than or equal to the first theoretical temperature change parameter within a preset time period, the air conditioner is controlled to stop and feedback is provided, or the lockable unit is controlled to stop for a preset time period, and the indoor fan runs at maximum speed for a preset time period.

[0149] This application provides an air conditioning control method. By responding to the air conditioner's heating operation command, the method acquires the first return air temperature, the first condensing temperature, and the first outdoor ambient temperature. Based on these three temperatures, it determines a first heat load corresponding to at least two time points and, based on the change information of the first heat load, determines a first theoretical temperature change parameter. Based on the relationship between the first theoretical temperature change parameter and the first temperature change parameter of the first return air temperature, it controls the air conditioner to adjust its operating state. This solution calculates the first heat load of the air conditioner during heating operation and determines the theoretical change parameter corresponding to the indoor ambient temperature based on the change. Furthermore, it compares the actual return air temperature (i.e., the first return air temperature, representing the indoor ambient temperature) with the theoretical change parameter. That is, it determines whether the air conditioner's detected return air temperature accurately represents the actual indoor ambient temperature and whether the deviation between the return air temperature and the actual ambient temperature is large, thus further adapting the air conditioner. This avoids the accumulation of hot air at the return air vent during heating operation, which could affect indoor temperature detection and improve the accuracy of air conditioning control.

[0150] It is understandable that, due to the higher density of cold air, the ambient temperature readings in cooling mode are generally quite accurate. This invention performs parameter judgment in cooling mode to calculate the coefficient of influence of the installation environment on the current air conditioner. Furthermore, without adding an ambient temperature sensor, this application can automatically determine whether there is a heat accumulation state in the system based on the existing parameters of the air conditioning system. Also, because indoor ambient temperature varies greatly, the system heat load is calculated using the relatively stable operating parameters of the outdoor unit, supplemented and corrected by the indoor and outdoor ambient temperatures and the set temperature. Furthermore, when heat accumulation is detected in the system, the temperature-reaching shutdown control is canceled while the fan speed is increased, avoiding the poor user experience caused by periodically operating the fan without judgment.

[0168] The formula for calculating the heat load is as follows:

[0169]

[0170] Wherein, Q is the first heat load, c is the heat load correction coefficient, T3B is the inlet temperature, T3A is the outlet temperature, and L is the preset system flow parameter corresponding to the air conditioner.

[0172] Calculate the first temperature change parameter based on the first return air temperature obtained within a preset time period;

[0173] If the first temperature change parameter is greater than the first theoretical temperature change parameter, the air conditioner is controlled to exit the preset temperature-reaching shutdown control logic, and the internal fan speed of the air conditioner is controlled to increase.

[0174] In one embodiment of this application, the control module 703, after controlling the air conditioner to exit the preset temperature-reaching shutdown control logic and controlling the indoor fan speed of the air conditioner to increase, specifically further includes:

[0175] Reacquire the first return air temperature and calculate the new temperature change parameters based on the reacquired first return air temperature;

[0176] If the new temperature change parameter is less than or equal to the first theoretical temperature change parameter, the air conditioner is controlled to re-enter the preset temperature-reaching shutdown control logic, and the internal fan speed of the air conditioner is controlled to resume.

[0177] In one embodiment of this application, the response acquisition module 701 is used to respond to the heating operation command of the air conditioner and acquire the first return air temperature, the first condensing temperature, and the first outdoor ambient temperature of the air conditioner, specifically including:

[0178] In response to the heating operation command of the air conditioner, the indoor fan of the air conditioner is controlled to run at maximum speed for a preset time, and the first return air temperature and the first outdoor ambient temperature at each time point are obtained according to the preset acquisition frequency.
