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.

[0054] Currently, with the rapid development of air conditioners, more and more users are adopting energy-saving inverter fresh air conditioners for cooling or heating, ensuring sufficient fresh air is supplied from the outside to the inside even in a closed indoor environment. However, existing fresh air conditioners, when introducing fresh air from the outside, can lead to excessively high positive and negative pressure levels indoors, and the large heat and humidity loads of the fresh air result in excessive energy consumption, affecting the operating performance of the air conditioner.

[0055] Based on this, this application proposes an air conditioning control method, device, equipment, and computer-readable storage medium to solve the technical problem in the prior art where the indoor positive and negative pressure of the air conditioner is too high in the fresh air mode, and the fresh air heat load and humidity load are large, resulting in excessive air conditioning energy consumption.

[0056] 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 smart fresh air conditioner, such as a portable air conditioner, window air conditioner, wall-mounted air conditioner, or floor-standing air conditioner installed in each room. Optionally, the air conditioner can also be an air conditioning cluster composed of multiple air conditioners.

[0057] 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 the present application. The air conditioning control scenario in this embodiment includes an air conditioner 100 (the air conditioner 100 integrates an air conditioning control device), and the air conditioner 100 has a computer-readable storage medium corresponding to the air conditioning control method running in it to execute the steps of the air conditioning control method.

[0058] Understandable, Figure 1 The air conditioner in the air conditioning control method scenario shown, or the device contained in the air conditioner, does not constitute a limitation on the embodiments of the present invention. That is, the number or type of air conditioner in the air conditioning control method scenario, or the number or type of device contained in each device, does 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 can be an independent air conditioner, such as a portable air conditioner, window air conditioner, wall-mounted air conditioner, or cabinet air conditioner installed in each room, or it can be an air conditioning control network or air conditioning control cluster composed of multiple air conditioners.

[0061] This application provides an air conditioning control method, apparatus, device, and computer-readable storage medium, which will be described in detail below.

[0062] It will be understood by those skilled in the art that Figure 1 The application environment shown is only one application scenario related to the solution of this application and does not constitute a limitation on the application scenario of this application. Other application environments may include more than one application scenario. Figure 1 The number of more or fewer air conditioners shown, or the air conditioning control network connections, for example Figure 1 Only one air conditioner is shown in the figure. It is understood that the scenario of the air conditioning control method may also include one or more air conditioners, which is not limited here. The air conditioner may also include a memory for storing the fresh air temperature and exhaust air temperature of the target air conditioner.

[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, various embodiments of the air conditioning control method disclosed in this invention are proposed.

[0065] like Figure 2 As shown, Figure 2 This is a flowchart illustrating one embodiment of the air conditioning control method in this application. The air conditioning control method includes the following steps 201 to 203:

[0066] 201. Respond to the air conditioning control request and obtain the target air conditioner corresponding to the air conditioning control request;

[0067] The air conditioning control method in this embodiment is applied to an air conditioner. The type and number of air conditioners are not specifically limited; that is, the air conditioner can be one or more smart air conditioners, such as portable air conditioners, window air conditioners, wall-mounted air conditioners, and floor-standing air conditioners installed in various rooms. In one specific embodiment, the air conditioner is a target air conditioner, which is a smart window air conditioner.

[0068] Specifically, the air conditioner responds to the air conditioning control request, obtains the target air conditioner corresponding to the air conditioning control request, detects the fresh air temperature and exhaust air temperature of the target air conditioner, determines the fresh air heat load and indoor air pressure status based on the fresh air temperature and exhaust air temperature, and adjusts the fresh air operation status of the target air conditioner based on the fresh air heat load and indoor air pressure status.

[0069] Specifically, during operation, the air conditioner responds to air conditioning control requests. These requests are operational instructions that drive the air conditioner to adjust its fresh air operation based on the fresh air temperature and exhaust air temperature. The triggering method for these control requests is not specifically limited; they can be actively triggered by the user, for example, by clicking the air conditioning control button on a remote control device connected to the air conditioner. Optionally, the control requests can also be automatically triggered by the air conditioner, for example, by pre-setting a fresh air control process that automatically triggers the control requests within a preset time.

[0070] Specifically, after receiving an air conditioning control request, the air conditioner parses the request and obtains the target air conditioner corresponding to it. Optionally, if the air conditioner is a standalone smart air conditioner, then that air conditioner is the target air conditioner corresponding to the control request. If the air conditioner contains several sub-air conditioners, the air conditioner obtains the air conditioner identifier from the control request, iterates through the sub-air conditioners based on the identifier, and obtains the target air conditioner corresponding to that identifier.

[0071] Specifically, after acquiring the target air conditioner to be adjusted, the air conditioner also acquires the fresh air temperature and exhaust air temperature of the target air conditioner, and determines the fresh air operation status of the target air conditioner based on the fresh air temperature and exhaust air temperature.

[0072] 202. Obtain the fresh air temperature and exhaust air temperature of the target air conditioner, and determine the fresh air heat load and indoor air pressure state based on the fresh air temperature and the exhaust air temperature;

[0073] Specifically, after responding to the air conditioning control request, the air conditioner collects the fresh air temperature and exhaust air temperature of the target air conditioner through a preset temperature difference sensor, and determines the fresh air heat load and indoor air pressure status corresponding to the target air conditioner after turning on the fresh air mode based on the fresh air temperature and exhaust air temperature.

[0074] Specifically, such as Figure 3 As shown, Figure 3 This is a schematic diagram of the structure of one embodiment of the target air conditioner in this application. Specifically, the target air conditioner includes an evaporator 1, a centrifugal fan 2, a dual-shaft motor 3, a compressor 4, an axial fan 5, a condenser 6, an exhaust valve 7, a fresh air valve 8, and a shell-and-tube heat exchanger 9. The target air conditioner is equipped with a fresh air system, which includes a fresh air duct and an exhaust duct, and the shell-and-tube heat exchanger 9 is fitted onto the fresh air duct and the exhaust duct.

[0075] Specifically, the target air conditioner is also equipped with a pre-installed temperature difference sensor, which is a multi-directional temperature difference sensor. The air conditioner obtains the temperature data from this sensor to determine the temperatures at various points in the fresh air inlet and outlet and the exhaust air inlet and outlet, thus obtaining the fresh air temperature and exhaust air temperature. The fresh air temperature includes both the fresh air inlet and outlet temperatures. The exhaust air temperature includes both the exhaust air inlet and outlet temperatures.

[0076] Specifically, the air conditioner uses the temperature difference sensor to collect the fresh air inlet temperature and the fresh air outlet temperature of the target air conditioner. It also uses the temperature difference sensor to collect the exhaust air inlet temperature and the exhaust air outlet temperature of the target air conditioner, and uses these temperatures to determine the fresh air heat load and indoor air pressure status under the target air conditioner's fresh air operation mode.

[0077] Specifically, the air conditioner obtains the temperature difference relationship between the fresh air inlet and outlet and the exhaust air inlet and outlet based on the obtained fresh air temperature and exhaust air temperature, and determines the fresh air heat load and indoor air pressure status when the target air conditioner fresh air mode is started based on the obtained temperature difference relationship.

[0078] Specifically, the air conditioner calculates the temperature difference between the fresh air inlet temperature and the fresh air outlet temperature to obtain the first temperature difference of the target air conditioner. This first temperature difference is the temperature difference data that characterizes the temperature difference relationship between the fresh air duct inlet and the fresh air duct outlet.

[0079] Specifically, the air conditioner calculates the temperature difference between the exhaust inlet temperature and the exhaust outlet temperature to obtain the second temperature difference of the target air conditioner. This second temperature difference is the temperature difference data that characterizes the temperature difference relationship between the exhaust duct inlet and the exhaust duct outlet.

[0080] Specifically, the air conditioner also calculates the temperature difference between the fresh air outlet temperature and the exhaust air inlet temperature to obtain the third temperature difference of the target air conditioner. This third temperature difference is the temperature difference data that characterizes the temperature difference relationship between the fresh air duct outlet and the exhaust air duct inlet.

[0081] Specifically, the air conditioner calculates the temperature difference between the fresh air inlet temperature and the exhaust air outlet temperature to obtain the fourth temperature difference of the target air conditioner. This fourth temperature difference is the temperature difference data that characterizes the temperature difference relationship between the fresh air duct inlet and the exhaust air outlet.

[0082] After obtaining the first temperature difference, the second temperature difference, the third temperature difference, and the fourth temperature difference, the air conditioner determines the fresh air heat load of the target air conditioner based on the first and second temperature differences, determines the indoor air pressure status of the target air conditioner based on the third and fourth temperature differences, and adjusts the fresh air operation status of the target air conditioner based on the fresh air heat load and the indoor air pressure status.

[0083] 203. Adjust the fresh air operation status of the target air conditioner according to the fresh air heat load and the indoor air pressure status.

[0084] Specifically, after acquiring the fresh air heat load and indoor air pressure status of the target air conditioner, the air conditioner adjusts the fresh air operation status of the target air conditioner according to the fresh air heat load and indoor air pressure status. In one specific embodiment, the fresh air heat load of the target air conditioner includes low heat load and high heat load.

[0085] Specifically, after determining the fresh air heat load and indoor air pressure status of the target air conditioner, the air conditioner obtains the exhaust adjustment parameters corresponding to the fresh air heat load and the fresh air adjustment parameters corresponding to the indoor air pressure status. Based on the exhaust adjustment parameters, the air conditioner adjusts the operating status of the exhaust valve and the fresh air valve, thereby controlling the fresh air volume and exhaust volume of the target air conditioner. This, in turn, adjusts the fresh air heat load and indoor air pressure status of the target air conditioner, ensuring that the indoor heat load is moderate and that the compressor of the target air conditioner can operate at a good working frequency, thus reducing the energy consumption of the air conditioner.

[0086] Optionally, the air conditioner can also determine the fresh air adjustment parameters of the target air conditioner based on the fresh air heat load and the fresh air temperature and exhaust air temperature of the target air conditioner, and can also determine the fresh air adjustment parameters of the target air conditioner based on the indoor air pressure state and the fresh air temperature and exhaust air temperature of the target air conditioner, so as to improve the adjustment accuracy.

[0087] In this embodiment, the air conditioner responds to an air conditioning control request, obtains the target air conditioner corresponding to the control request, acquires the fresh air temperature and exhaust air temperature of the target air conditioner, determines the fresh air heat load and indoor air pressure state based on the fresh air temperature and exhaust air temperature, and adjusts the fresh air operation state of the target air conditioner according to the fresh air heat load and indoor air pressure state. This achieves the goal of determining the air conditioner's heat load and indoor air pressure state by collecting the fresh air inlet and outlet temperatures and the exhaust air inlet and outlet temperatures, thereby adjusting the air conditioner's fresh air state based on the heat load and air pressure state, improving the air conditioning's fresh air effect, and reducing air conditioning energy consumption.

[0088] like Figure 4 As shown, Figure 4 A flowchart illustrating one embodiment of the air conditioning control method for determining the fresh air heat load provided in this application is shown, specifically including steps 301 to 303:

[0089] 301. If the first temperature difference between the first temperature difference and the second temperature difference is greater than a preset heat load threshold, then compare the first temperature difference and the second temperature difference;

[0090] 302. If the first temperature difference is greater than the second temperature difference, then the fresh air heat load of the target air conditioner is determined to be a low heat load;

[0091] 303. If the first temperature difference is less than the second temperature difference, then the fresh air heat load of the target air conditioner is determined to be a high heat load.

[0092] Based on the above embodiments, in this embodiment, after the air conditioner obtains the first temperature difference, the second temperature difference, the third temperature difference, and the fourth temperature difference, it determines the fresh air heat load and indoor air pressure status of the target air conditioner according to the first temperature difference, the second temperature difference, the third temperature difference, and the fourth temperature difference.

[0093] Specifically, the air conditioner is pre-set with a preset heat load threshold for judging the fresh air heat load status, and the target air conditioner's fresh air heat load is judged by the preset heat load threshold, the first temperature difference, and the second temperature difference.

[0094] Specifically, the air conditioner obtains the first temperature difference between the first temperature difference and the second temperature difference, and compares the first temperature difference with a preset heat load threshold. If the first temperature difference is greater than the preset heat load threshold, the fresh air heat load of the target air conditioner is determined by comparing the first temperature difference and the second temperature difference.

[0095] Optionally, if the first temperature difference is greater than the preset heat load threshold and the first temperature difference is greater than the second temperature difference, that is, the current fresh air inlet and outlet temperature difference of the target air conditioner is greater than the exhaust air inlet and outlet temperature difference, then the air conditioner determines that the fresh air heat load of the target air conditioner is a low heat load.

[0096] Optionally, if the first temperature difference is greater than the preset heat load threshold and the first temperature difference is less than the second temperature difference, that is, the current fresh air inlet and outlet temperature difference of the target air conditioner is less than the exhaust air inlet and outlet temperature difference, then the air conditioner determines that the fresh air heat load of the target air conditioner is a high heat load.

[0097] Specifically, the air conditioner is pre-set with a preset air pressure threshold to determine the indoor air pressure status, and the indoor air pressure status of the target air conditioner is determined based on the third temperature difference, the fourth temperature difference and the preset air pressure threshold.

[0098] Specifically, the air conditioner obtains the second temperature difference between the third and fourth temperature differences, and compares the second temperature difference with a preset air pressure threshold. If the second temperature difference is greater than the preset air pressure threshold, the third and fourth temperature differences are compared, and the indoor air pressure status of the target air conditioner is determined based on the comparison result.

[0099] Optionally, if the second temperature difference is greater than the preset air pressure threshold and the third temperature difference is greater than the fourth temperature difference, meaning the fresh air volume of the target air conditioner is greater than the exhaust air volume of the target air conditioner and the difference is too large, thus causing excessive positive pressure in the room, then the air conditioner determines that the indoor air pressure state of the target air conditioner is a positive pressure state. Here, the positive pressure state is a status indicator representing excessive positive pressure in the operating area of ​​the target air conditioner.

[0100] Optionally, if the second temperature difference is greater than the preset air pressure threshold and the third temperature difference is less than the fourth temperature difference, that is, the fresh air volume of the target air conditioner is less than the exhaust air volume of the target air conditioner and the difference is too large, thus causing the indoor negative pressure to be too large, then the air conditioner determines that the indoor air pressure state of the target air conditioner is a negative pressure state.

[0101] After obtaining the fresh air heat load and indoor air pressure status of the target air conditioner, the air conditioner controls the fresh air volume and exhaust volume of the target air conditioner according to the fresh air heat load and indoor air pressure status, thereby adjusting the fresh air heat load and indoor air pressure status of the target air conditioner to ensure that the indoor heat load is moderate and that the compressor of the target air conditioner can operate at a good working frequency, thereby reducing the energy consumption of the air conditioner.

[0102] In this embodiment, the air conditioner compares a first temperature difference value with a preset heat load threshold. If the first temperature difference value between the first temperature difference and the second temperature difference is greater than the preset heat load threshold, then the first temperature difference and the second temperature difference are compared. If the first temperature difference is greater than the second temperature difference, then the fresh air heat load of the target air conditioner is determined to be a low heat load. If the first temperature difference is less than the second temperature difference, then the fresh air heat load of the target air conditioner is determined to be a high heat load. This effectively determines the fresh air heat load and indoor air pressure status of the target air conditioner based on the temperature difference at various locations in the exhaust duct and fresh air duct.

[0103] like Figure 5 As shown, Figure 5 A flowchart illustrating an embodiment of the air conditioning control method provided in this application for adjusting the fresh air operation state of the target air conditioner according to the fresh air heat load and the indoor air pressure state, specifically including steps 401 to 403:

[0104] 401. Determine the exhaust adjustment parameters of the target air conditioner based on the fresh air heat load and the fresh air temperature and exhaust air temperature of the target air conditioner;

[0105] 402. Determine the fresh air adjustment parameters of the target air conditioner based on the indoor air pressure status and the fresh air temperature and exhaust air temperature of the target air conditioner;

[0106] 403. Adjust the fresh air operation status of the target air conditioner according to the exhaust adjustment parameters and the fresh air adjustment parameters.

[0107] Based on the above embodiments, in this embodiment, after the air conditioner obtains the fresh air heat load and indoor air pressure status of the target air conditioner, it adjusts the fresh air operation status of the target air conditioner according to the fresh air heat load and indoor air pressure status.

[0108] Specifically, after obtaining the fresh air heat load of the target air conditioner, the air conditioner determines the exhaust adjustment parameters of the target air conditioner based on the fresh air heat load and the fresh air temperature and exhaust air temperature of the target air conditioner.

[0109] Specifically, the air conditioner determines the first temperature difference, second temperature difference, third temperature difference, and fourth temperature difference of the target air conditioner based on the fresh air temperature and the exhaust air temperature, calculates the temperature difference between the first temperature difference and the second temperature difference to obtain the first temperature difference value, and determines the exhaust air adjustment parameters of the target air conditioner based on the first temperature difference value and the fresh air heat load.

[0110] Specifically, if the fresh air heat load is a low heat load, the air conditioner obtains the low heat load database corresponding to the low heat load, and obtains the exhaust adjustment parameters corresponding to the first temperature difference value in the low heat load database. The air conditioner adjusts the exhaust valve operation status of the target air conditioner according to the exhaust adjustment parameters, that is, adjusts the opening degree of the exhaust valve to control the exhaust volume of the target air conditioner.

[0111] Specifically, if the fresh air heat load is a high heat load, the air conditioner obtains the high heat load database corresponding to the high heat load, and obtains the exhaust adjustment parameters corresponding to the first temperature difference value in the high heat load database. The air conditioner then adjusts the exhaust valve operation state of the target air conditioner according to these exhaust adjustment parameters, i.e., adjusts the exhaust valve opening degree to control the exhaust volume of the target air conditioner. The low heat load database and the high heat load database are preset heat load databases in the air conditioner.

[0112] Specifically, the air conditioner also calculates the second temperature difference between the third and fourth temperature differences, and determines the fresh air adjustment parameters of the target air conditioner based on this second temperature difference and the indoor air pressure status.

[0113] Specifically, if the indoor air pressure is positive, the air conditioner accesses the positive pressure database corresponding to the positive pressure state, obtains the fresh air adjustment parameters corresponding to the second temperature difference value in the positive pressure database, and adjusts the opening degree of the fresh air valve of the target air conditioner according to the fresh air adjustment parameters, thereby controlling the fresh air volume of the target air conditioner.
