Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in this application.

[0059] At present, with the rapid development of the field of air-conditioning technology, more and more users have higher requirements for the installation space and energy saving of air conditioners. Therefore, air-conditioning systems such as one-to-many air conditioners have emerged to save installation space and improve energy-saving effects. Among them, a one-to-many air conditioner is an air-conditioning system that can connect multiple indoor units at the same time, usually consisting of an outdoor unit and multiple indoor units. The refrigerant can be transmitted to each indoor unit through a pipe to achieve cooling or heating of multiple rooms. However, the existing one-to-many air conditioners have the problem that when users choose to turn on different numbers of indoor units and different capacities of indoor units, because the total capacity of the indoor units is different and the capacity of each indoor unit is also different, the output cooling capacity (heating capacity) is different, it is difficult to quickly achieve stable operation of the compressor, and it is difficult for indoor units of each capacity to quickly reach the target capacity output.

[0060] Based on this, the present application proposes an air conditioning control method, device, equipment and computer-readable storage medium to solve the technical problem in the prior art that the air conditioning output effect of a one-to-many air conditioner is poor when different indoor units are turned on.

[0061] The air conditioning control method in the embodiment of the present invention is applied to an air conditioning control device, which is arranged in an air conditioner, and one or more processors, memories, and one or more applications are arranged in the air conditioner, wherein the one or more applications are stored in the memories and are configured to be executed by the processor to implement the air conditioning control method; wherein the air conditioner can be a one-to-many air conditioner. Among them, the one-to-many air conditioner is an air conditioning system that can simultaneously connect multiple indoor units, usually consisting of an outdoor unit and multiple indoor units. The refrigerant can be transmitted to each indoor unit through a pipeline to realize the air conditioning equipment of cooling or heating multiple rooms.

[0062] like Figure 1 As shown, Figure 1 This is a scene diagram of the air-conditioning control method of an embodiment of the present application. The air-conditioning control scene in the embodiment of the present invention includes an air conditioner 100 (an air-conditioning control device is integrated in the air conditioner 100), and a computer-readable storage medium corresponding to the air-conditioning control method is running in the air conditioner 100 to execute the steps of the air-conditioning control method.

[0063] Understandably, Figure 1 The air conditioner in the air conditioning control method scenario shown, or the devices included in the air conditioner, does not constitute a limitation on the embodiments of the present invention, that is, the number of air conditioner devices and types of devices included in the air conditioning control method scenario, or the number of devices and types of devices included in each device, do not affect the overall implementation of the technical solution in the embodiments of the present invention, and can all be regarded as equivalent replacements or derivatives of the technical solution claimed to be protected in the embodiments of the present invention.

[0064] The air conditioner 100 in the embodiment of the present invention is mainly used for: responding to a one-to-many air conditioner control request, obtaining the capacity ratio of the indoor unit of the air conditioner in operation and the target outdoor unit, and determining the initial compressor frequency and the initial expansion valve opening according to the indoor unit capacity ratio; calculating the operating temperature difference corresponding to each of the air conditioner operating indoor units according to the inner ring temperature of the target operating area and the set temperature of each of the air conditioner operating indoor units; correcting the initial compressor frequency, the initial expansion valve opening and / or the initial operating gear of the air conditioner operating indoor unit according to the operating temperature difference to obtain target operating parameters; and driving the air conditioner operating indoor unit and / or the target outdoor unit to operate according to the target operating parameters.

[0065] The embodiments of the present application provide an air conditioning control method, an apparatus, an air conditioner, and a computer-readable storage medium, which are described in detail below.

[0066] It can be understood by those skilled in the art that Figure 1 The application environment shown in is only one of the application scenarios related to the present application solution and does not constitute a limitation on the application scenario of the present application solution. Other application environments may also include Figure 1 More or fewer air conditioners, or air conditioner control network connections, are shown, for example Figure 1 Only one air conditioner is shown in the figure. It can be understood that the scenario of the air conditioning control method can also include multiple air conditioner indoor units, which is not specifically limited here; the air conditioner 100 can also include a memory for storing air conditioning capacity data and other data.

[0067] It should be noted that Figure 1 The scene diagram of the air-conditioning control method shown is only an example. The scene of the air-conditioning control method described in the embodiment of the present invention is to more clearly illustrate the technical solution of the embodiment of the present invention, and does not constitute a limitation on the technical solution provided by the embodiment of the present invention.

[0068] Based on the scenario of the above air-conditioning control method, various embodiments of the air-conditioning control method disclosed in the present invention are proposed.

[0069] like Figure 2 As shown, Figure 2 This is a flow chart of an embodiment of an air conditioning control method in an embodiment of the present application. The air conditioning control method includes the following steps 201 to 204:

[0070] 201. In response to a one-to-many air conditioner control request, obtain a capacity ratio of the indoor unit of the air conditioner in operation to the target outdoor unit, and determine an initial compressor frequency and an initial expansion valve opening according to the capacity ratio of the indoor unit;

[0071] The air conditioning control method in this embodiment is applied to air conditioners, and the type and number of air conditioners are not specifically limited, that is, the air conditioner can be a one-to-many air conditioner, wherein the one-to-many air conditioner is an air conditioning system that can simultaneously connect multiple indoor units, usually consisting of an outdoor unit and multiple indoor units. The refrigerant can be transmitted to each indoor unit through a pipeline to achieve cooling or heating or other air conditioning of multiple rooms.

[0072] Specifically, the existing one-to-many air conditioner has a problem that when the user chooses to turn on different numbers of indoor units and different capacities of indoor units, the output cooling capacity (heating capacity) is different because the total capacity of the indoor units is different and the capacity of each indoor unit is also different, which makes it difficult to quickly achieve the stable operation of the compressor and the indoor units of each capacity are difficult to quickly reach the target capacity output. Based on this, the air conditioner responds to the one-to-many air conditioner control request during operation, wherein the one-to-many air conditioner control request is an operation event that drives the air conditioner to control the operation of multiple air conditioner indoor units and associated target outdoor units to quickly achieve the stable operation of the one-to-many air conditioner and reach the target output capacity. Among them, the triggering method of the one-to-many air conditioner control request is not specifically limited here, that is, the one-to-many air conditioner control request can be actively triggered by the user, for example, the user actively triggers the one-to-many air conditioner control request by clicking the air conditioner or the air conditioner control button in the remote control device (such as a remote control or a smart phone, etc.) that is connected to the air conditioner. In addition, the air conditioning control request can also be automatically triggered by the air conditioner. For example, a one-to-many air conditioning control process is set in the air conditioning master control of the air conditioner. When it is detected that multiple indoor units are in operation at the same time, the one-to-many air conditioning control request is automatically triggered.

[0073] Specifically, after obtaining the one-to-many air conditioning control request, the air conditioner also obtains the ratio of the indoor unit capacity between the running indoor unit of the air conditioner and the target outdoor unit, and determines the initial compression frequency and initial expansion valve opening of the air conditioner through the ratio of the indoor unit capacity. Wherein, the running indoor unit is the indoor unit of the air conditioner that is in the running state. The target outdoor unit is the outdoor unit of the air conditioner connected to the pipes of each indoor unit of the air conditioner. Wherein, the air conditioner includes multiple indoor units and one outdoor unit of the air conditioner, and the outdoor unit of the air conditioner is connected to the pipes of multiple indoor units of the air conditioner through a pipe. Wherein, the ratio of the indoor unit capacity is the ratio of the indoor unit capacity of the running indoor unit currently started by the air conditioner to the outdoor unit capacity. Wherein, the ratio of the indoor unit capacity includes the ratio of the total running capacity and the ratio of the independent indoor unit capacity, wherein the total running capacity ratio is the ratio of the total indoor unit capacity of the running indoor unit currently started by the air conditioner to the capacity of the outdoor unit, and the total indoor unit capacity can reflect the cooling capacity or heating capacity occupied by all the running indoor units currently started by the air conditioner. The independent indoor unit capacity ratio is used to characterize the cooling capacity or heating capacity of the target outdoor unit occupied by a specified individual air-conditioning indoor unit. The indoor unit capacities of the air-conditioning indoor units in the air conditioner can be the same or different, so as to meet the air conditioning needs of different operating areas.

[0074] Specifically, after determining each air-conditioning running indoor unit currently started, the air conditioner obtains the air-conditioning indoor unit capacity of each air-conditioning running indoor unit stored in the information storage unit and the outdoor unit capacity of the target outdoor unit in the air conditioner by reading the designated information storage unit. And the indoor unit capacity ratio between each air-conditioning running indoor unit in the air conditioner and the target outdoor unit is calculated according to the air-conditioning indoor unit capacity and the air-conditioning outdoor unit capacity. That is, the air conditioner determines the independent indoor unit capacity ratio of the air-conditioning running indoor unit by calculating the ratio between the air-conditioning indoor unit capacity of each air-conditioning running indoor unit and the air-conditioning outdoor unit capacity of the target outdoor unit. And, the air conditioner can also obtain the total operating capacity ratio of the air conditioner by calculating the ratio between the sum of the air-conditioning indoor unit capacities of all the air-conditioning running indoor units in the air conditioner and the air-conditioning outdoor unit capacity of the target outdoor unit, and determine the independent indoor unit capacity ratio and the total operating capacity ratio as the indoor unit capacity ratio.

[0075] Specifically, after determining the capacity ratio of the indoor unit, the air conditioner also determines the initial compressor frequency of the air conditioner and the initial expansion valve opening corresponding to each indoor unit of the air conditioner according to the total operating capacity ratio and the independent indoor unit capacity ratio.

[0076] Specifically, after obtaining the total operating capacity ratio of the air conditioner, the air conditioner determines the initial compressor frequency of the target outdoor unit in the air conditioner through the total operating capacity ratio and the preset frequency mapping data table. The preset mapping data table is shown in Table 1:

[0077]

[0078] Table 1 Preset frequency mapping data table

[0079] Specifically, after determining the total operating capacity ratio of the air conditioner, the air conditioner inputs the total operating capacity ratio into the preset frequency mapping data table to determine the initial compressor frequency of the target outdoor unit in the air conditioner. The preset frequency mapping data table is a mapping data table obtained by performing a working condition experiment on the air conditioner to obtain the mapping relationship between the compressor frequency and the total operating capacity in a better operating state under different total operating capacities. The larger the total operating capacity ratio, the larger the corresponding initial compressor frequency.

[0080] Specifically, after obtaining the independent indoor unit capacity ratio corresponding to each running indoor unit in the air conditioner, the air conditioner also determines the initial expansion valve opening corresponding to each running indoor unit of the air conditioner according to the independent indoor unit capacity ratio corresponding to each running indoor unit of the air conditioner and the preset opening mapping data table. The preset opening mapping data table is shown in Table 2:

[0081]

[0082] Specifically, after the air conditioner obtains the independent indoor unit capacity ratio of each operating indoor unit, it queries the expansion valve opening corresponding to the independent indoor unit capacity ratio in the preset opening mapping data table, and sets the expansion valve opening to the initial expansion valve opening of the operating indoor unit corresponding to the independent indoor unit capacity ratio. Among them, the preset opening mapping data table is a mapping data table of the mapping relationship between the expansion valve opening of the optimal working condition corresponding to different independent indoor unit capacity ratios obtained by delaying the working condition of each air-conditioning indoor unit in the air conditioner and the independent indoor unit capacity ratio. Among them, the preset independent indoor unit capacity ratio of the operating indoor unit increases successively, and the corresponding target opening decreases successively.

[0083] 202. Calculate the operating temperature difference corresponding to each of the operating indoor units of the air conditioner according to the inner ring temperature of the target operating area and the set temperature of each of the operating indoor units of the air conditioner;

[0084] Specifically, after the air conditioner determines the initial compressor frequency of the target outdoor unit and the initial expansion valve opening of each operating indoor unit, it drives the target outdoor unit of the air conditioner according to the initial compressor frequency, and drives the operating indoor unit to operate for the first operating time according to the initial expansion valve opening, and then collects the inner ring temperature of the target operating area associated with each air conditioner operating indoor unit, and after obtaining the inner ring temperature of the target operating area, it also calculates the operating temperature difference of each air conditioner indoor unit according to the inner ring temperature in the target operating area associated with each air conditioner operating indoor unit and the set temperature of each air conditioner operating indoor unit. Among them, the operating temperature difference is the temperature difference between the inner ring temperature in the target operating area and the indoor unit of the air conditioner operating indoor unit after the specified air conditioner operating indoor unit has been running for a certain period of time at the initial expansion valve opening and the initial compressor frequency. Among them, the inner ring temperature of each target air conditioner operating area can be detected by the temperature sensor in the corresponding air conditioner operating indoor unit, and this embodiment does not make specific limitations.

[0085] Specifically, after obtaining the inner loop temperature of the target operating area, the air conditioner also obtains the set temperature of the air conditioner operating indoor unit corresponding to each target operating area, and calculates the temperature difference between the inner loop temperature and the set temperature, and determines the temperature difference between the inner loop temperature and the set temperature as the operating temperature difference corresponding to the air conditioner operating indoor unit.

[0086] 203. Correct the initial compressor frequency, the initial expansion valve opening and / or the initial operating gear of the air conditioner indoor unit according to the operating temperature difference to obtain target operating parameters;

[0087] Specifically, after obtaining the operating temperature difference value of each air-conditioning indoor unit, the air conditioner also corrects the initial compressor frequency and initial expansion valve opening of the air conditioner and / or the initial operating gear of each air-conditioning indoor unit in the air conditioner according to the operating temperature difference value, so as to obtain the target operating parameters that can quickly adjust the operating effect of each air-conditioning indoor unit or the target outdoor unit. The initial operating gear is a gear that represents the current indoor unit operating gear of the air-conditioning indoor unit. For example, the initial operating gear can be the current fan gear, the current cooling gear, and other current operating gears of the air-conditioning indoor unit.

[0088] Specifically, after obtaining the operating temperature difference value of each air-conditioning running indoor unit, the air conditioner determines whether the operating temperature difference value is within a preset target temperature difference interval, wherein the target temperature difference interval is a temperature difference interval that characterizes whether the operating state of the air-conditioning running indoor unit is stable. If the operating temperature difference value is within the target temperature difference interval, the air conditioner determines that the operating state of the air-conditioning running indoor unit corresponding to the operating temperature difference value is stable, and there is no need to correct the control parameters of the air-conditioning running indoor unit. Optionally, in a specific embodiment, the target temperature difference interval is {|△T||0≤|△T|≤0.5}. That is, when the absolute value of the operating temperature difference value of the air-conditioning running indoor unit is greater than or equal to 0, and less than or equal to 0.5, the air conditioner determines that the operating state of the air-conditioning running indoor unit corresponding to the operating temperature difference value is stable, and there is no need to correct the control parameters of the air-conditioning running indoor unit.

[0089] Specifically, when the air conditioner determines that the operating temperature difference value of any air conditioner operating indoor unit is not within the target temperature difference interval, it determines that the parameters of the air conditioner operating indoor unit corresponding to the operating temperature difference value need to be corrected, thereby improving the operating stability of the air conditioner operating indoor unit. That is, after determining that the operating temperature difference value is not within the target temperature difference interval, the air conditioner further compares the operating temperature difference values ​​of each air conditioner operating indoor unit to determine a target temperature difference value among the operating temperature difference values, wherein the target temperature difference value is the minimum operating temperature difference value among the operating temperature difference values ​​that are not within the target temperature difference interval.

[0090] Specifically, after determining the target temperature difference value in the operating temperature difference value, the air conditioner also corrects the initial compressor frequency, the initial expansion valve opening and / or the initial operating gear of the air conditioner indoor unit according to the target temperature difference value and a preset temperature difference threshold to obtain target operating parameters, wherein the target operating parameters include any one or more of the target compressor frequency, the target expansion valve opening and the target operating gear.

[0091] Specifically, after obtaining the target temperature difference value, the air conditioner obtains a temperature difference comparison result by comparing the target temperature difference value with a preset temperature difference threshold value. The initial compressor frequency, the initial expansion valve opening and / or the initial operating gear of the air conditioner indoor unit are adjusted according to the temperature difference comparison result to obtain the target operating parameters.

[0092] 204. Drive the air conditioner indoor unit and / or the target outdoor unit to operate according to the target operating parameters.

[0093] Specifically, after determining the target compressor frequency, target expansion valve opening and target operating gear in the target operating parameters, the air conditioner drives the air conditioner to control the air conditioner indoor unit and / or the target outdoor unit to operate according to the target compressor frequency, target expansion valve opening and target operating gear, thereby reducing the difficulty of controlling the indoor units of a one-to-many air conditioner and optimizing the control logic of the indoor units to quickly achieve stable operation of the air conditioner and improve energy-saving effects.

[0094] Specifically, after determining the target compressor frequency, target expansion valve opening and target operating gear, the air conditioner drives the target outdoor unit to operate according to the target compressor frequency, and correspondingly adjusts the target expansion valve opening and target operating gear of each air-conditioning operating indoor unit, so that the operating temperature difference of each air-conditioning operating indoor unit can be within the target temperature difference range, thereby enabling the target outdoor unit and the air-conditioning operating indoor unit to operate quickly and stably.

[0095] In this embodiment, the air conditioner obtains the capacity ratio of the indoor unit between the operating indoor unit of the air conditioner and the target outdoor unit by responding to the control request of the one-to-many air conditioner, determines the initial compressor frequency and the initial expansion valve opening according to the capacity ratio of the indoor unit; calculates the operating temperature difference corresponding to each operating indoor unit of the air conditioner according to the inner ring temperature of the target operating area and the set temperature of each operating indoor unit of the air conditioner; corrects the initial compressor frequency, the initial expansion valve opening and / or the initial operating gear of the operating indoor unit of the air conditioner according to the operating temperature difference to obtain the target operating parameters; drives the operating indoor unit of the air conditioner and / or the target outdoor unit to operate according to the target operating parameters. The initial operating parameters of the one-to-many air conditioner are determined according to the capacity ratio of the indoor units in the one-to-many air conditioner, wherein the initial operating parameters include the initial compressor frequency, the initial expansion valve opening and the initial operating gear, and during the operation, the initial operating parameters are corrected according to the operating temperature difference of each operating indoor unit of the air conditioner, and the one-to-many air conditioner is driven to operate according to the corrected target operating parameters, so as to reduce the control difficulty of the indoor units of the one-to-many air conditioner and improve the operating stability and energy saving effect of the one-to-many air conditioner.

[0096] like Figure 3 As shown, Figure 3 This is a flow chart of an embodiment of performing parameter correction in the air conditioning control method provided in the embodiment of the present application. Specifically, in this embodiment, the air conditioning control method further includes steps 301 to 304:

[0097] 301. If the first target temperature difference value is greater than a first temperature difference threshold, the initial compressor frequency is increased according to a preset frequency correction function to obtain a target compressor frequency;

[0098] 302. If the first target temperature difference value is within the target temperature difference range, adjusting the initial expansion valve opening according to the second target temperature difference value to obtain a target expansion valve opening;

[0099] 303. Correcting the initial operating gear of each of the air conditioner indoor units according to the target expansion valve opening and the first temperature difference threshold to obtain a target operating gear;

[0100] 304. Determine the target compressor frequency, the target expansion valve opening and / or the target operating gear as the target operating parameters.

[0101] Based on the above embodiments, in this embodiment, after the air conditioner determines that the operating temperature difference value is not within the target temperature difference range, it also compares the operating temperature difference values ​​of each air conditioner's operating indoor units to determine the target temperature difference value in the operating temperature difference value, and uses the target temperature difference value to perform parameter correction on the air conditioner's initial compressor frequency, initial expansion valve opening and / or initial operating gear to obtain target operating parameters.

[0102] Specifically, the air conditioner obtains the first target temperature difference value in the operating temperature difference value, and compares the first target temperature difference value with the preset first temperature difference threshold value, and corrects the initial compressor frequency according to the comparison result to obtain the target compressor frequency. Wherein, the first target temperature difference value is the minimum operating temperature difference value among the current operating temperature difference values ​​when the air conditioner is in cooling mode. Wherein, the first temperature difference threshold value is a temperature difference threshold value for determining whether the initial compressor frequency needs to be corrected. Optionally, the first temperature difference threshold value may be the maximum interval threshold value of the target temperature difference interval. For example, in a specific embodiment, the target temperature difference interval is [0, 0.5], and the first temperature difference threshold value is 0.5. Optionally, in other embodiments, the first temperature difference threshold value may also be other threshold parameters except the maximum interval threshold value.

[0103] Optionally, if the comparison result is that the first target temperature difference value is greater than the first temperature difference threshold, the air conditioner increases the initial compressor frequency of the target outdoor unit according to a preset frequency correction function to obtain a target compressor frequency.

[0104] In a specific embodiment, the expression of the preset frequency correction function is:

[0105] f 目标 =f 初始 +y(y>0Hz)

[0106] Among them, f 目标 is the target compressor frequency, f 初始 is the initial compressor frequency, and y is the frequency correction coefficient.

[0107] That is, after determining that the first target temperature difference value is greater than the first temperature difference threshold, the air conditioner obtains the target compressor frequency by calculating the sum of the initial compressor frequency and the frequency correction coefficient, and drives the air conditioner to operate for the second operating time at the target compressor frequency, and then detects the updated first target temperature difference value. The updated first target temperature difference value is the current operating temperature difference value of the air conditioner operating indoor unit corresponding to the first target temperature difference value after the air conditioner operates for the second operating time at the target compressor frequency.

[0108] Optionally, if the updated first temperature difference value is not within the target temperature difference range, the air conditioner determines that the operating state of the air conditioner indoor unit corresponding to the updated target temperature difference value is an unstable operating state, and the air conditioner corrects the target compressor frequency again according to the preset frequency correction function until the updated target temperature difference value is within the target temperature difference range to obtain the final target compressor frequency, otherwise, continue to perform frequency correction according to the preset frequency correction function.

[0109] Optionally, if the updated first target temperature difference value is within the target temperature difference range, the air conditioner determines that the operating state of the air conditioner indoor unit corresponding to the updated first target temperature difference value tends to be stable, and stops updating and correcting the compressor frequency parameters.

[0110] Specifically, after determining that the updated first target temperature difference value is within the target temperature difference interval, the air conditioner also obtains a second target temperature difference value in the target temperature difference value, and adjusts the initial expansion valve opening associated with the air conditioner operating indoor unit corresponding to the second target temperature difference value according to the second target temperature difference value to obtain the target expansion valve opening. The second target temperature difference value is the minimum temperature difference value among the remaining operating temperature difference values ​​except the first target temperature difference value. That is, after the air conditioner uses the first target temperature difference value and / or the second target temperature difference value to adjust the parameters, the minimum temperature difference value among the current remaining operating temperature difference values ​​is set as the second target temperature difference value, so that the expansion valve opening of the remaining air conditioner operating indoor units in the air conditioner is corrected according to the second target temperature difference value.

[0111] Specifically, after the air conditioner obtains the second target temperature difference value in the operating temperature difference value, it also obtains the target operating indoor unit corresponding to the second target temperature difference value, and obtains the first expansion valve opening associated with the target operating indoor unit in the initial expansion valve opening, and uses the preset first opening correction function to reduce the first expansion valve opening until the updated second target temperature difference value is within the target temperature difference interval, and the expansion valve opening that makes the updated second target temperature difference value within the target temperature difference interval is determined as the target expansion valve opening of the air conditioner operating indoor unit corresponding to the second target temperature difference value. The expression of the opening correction function is as follows:

[0112] p 目标 =p 初始 -z(p 目标 ≥p min )

[0113] Among them, p 目标 is the target expansion valve opening, p 初始 is the initial expansion valve opening, z is the opening correction coefficient, p min It is the minimum expansion valve opening of the indoor unit of the air conditioner.

[0114] Optionally, after obtaining the target expansion valve opening, the air conditioner uses the target expansion valve opening to drive the air conditioner operating indoor unit corresponding to the second target temperature difference to operate for a third operating time, and collects an updated second target temperature difference value. When the updated second target temperature difference value is within the target temperature difference range, the target expansion valve opening is determined to be the target expansion valve opening of the air conditioner operating indoor unit. If the updated second target temperature difference value is not within the target temperature difference range, the first opening correction function is continued to be used to perform the opening correction operation until the updated second target temperature difference value is within the target temperature difference range.

[0115] Optionally, in other embodiments, after the air conditioner corrects the opening of the air conditioner operating indoor unit corresponding to the second target temperature difference value, the air conditioner also corrects the initial operating gear of each of the air conditioner operating indoor units according to the target expansion valve opening and the first temperature difference threshold to obtain the target operating gear. That is, when the target expansion valve opening of the air conditioner operating indoor unit is equal to the minimum expansion valve opening and the updated second target temperature difference value obtained after the third operating time according to the target expansion valve opening is still greater than the first temperature difference threshold, the air conditioner obtains the initial operating gear of the air conditioner operating indoor unit, and corrects the initial operating gear to obtain the target operating gear.

[0116] That is, when the air conditioner determines that the target expansion valve opening of the air conditioner running indoor unit is equal to the preset first opening threshold value and the updated second target temperature difference value is still greater than the first temperature difference threshold value after running for the third running time according to the target expansion valve opening, the air conditioner obtains the initial running gear of the air conditioner running indoor unit, and when it is determined that the initial running gear is greater than the first gear threshold value, the initial running gear is successively increased by one gear to obtain the target running gear, and the air conditioner running indoor unit is driven to run according to the target running gear, and each updated running temperature difference value is detected, and when the running temperature difference value is still greater than the first temperature difference threshold value, the target compressor frequency and the target expansion valve opening are corrected again until the running temperature difference value corresponding to each air conditioner running indoor unit is in the target temperature difference range. Among them, the first opening threshold value is the minimum expansion valve opening corresponding to the air conditioner running indoor unit. The first gear threshold value is the minimum running gear corresponding to the air conditioner running indoor unit.

[0117] Specifically, after obtaining the target compressor frequency, the target expansion valve opening and the target operating gear, the air conditioner determines the target compressor frequency, the target expansion valve opening and / or the target operating gear as the target operating parameter.

[0118] In this embodiment, the air conditioner determines that if the first target temperature difference value is greater than the first temperature difference threshold, the initial compressor frequency is increased according to the preset frequency correction function to obtain the target compressor frequency; if the first target temperature difference value is in the target temperature difference range, the initial expansion valve opening is adjusted according to the second target temperature difference value to obtain the target expansion valve opening; and / or, the initial operating gear of each air conditioner operating indoor unit is corrected according to the target expansion valve opening and the first temperature difference threshold to obtain the target operating gear; the target compressor frequency, the target expansion valve opening and / or the target operating gear are determined as the target operating parameters. The operating parameters in the air conditioner are corrected by the difference between the inner ring temperature and the set temperature in the operating area, the control logic of multiple air conditioners is optimized, and the operating stability of one-to-many air conditioners is improved.

[0119] like Figure 4 As shown, Figure 4 This is a flow chart of an embodiment of performing parameter correction in the air conditioning control method provided in the embodiment of the present application. Specifically, in this embodiment, the air conditioning control method further includes steps 401 to 404:

[0120] 401. If the operating temperature difference is less than a second temperature difference threshold, increasing the initial expansion valve opening corresponding to the operating temperature difference according to a preset second opening correction function to obtain a target expansion valve opening;

[0121] 402. If the target expansion valve opening is equal to a preset second opening threshold, and the target temperature difference value in the operating temperature difference value is less than the first temperature difference threshold, the initial operating gear is lowered according to a preset gear correction strategy to obtain a target operating gear;

[0122] 403. Drive the air conditioner to operate the indoor unit and / or the target outdoor unit according to the target expansion valve opening and the target operating gear to obtain an updated temperature difference value, and adjust the initial compressor frequency according to the updated temperature difference value to obtain a target compressor frequency;

[0123] 404. Determine the target compressor frequency, the target expansion valve opening and / or the target operating gear as the target operating parameters.

[0124] Based on the first embodiment, in this embodiment, after the air conditioner determines that the operating temperature difference value is not within the target temperature difference range, it also compares the operating temperature difference values ​​of each air-conditioning indoor unit to determine the target temperature difference value in the operating temperature difference value, and uses the target temperature difference value to perform parameter correction on the initial compressor frequency, initial expansion valve opening and / or initial operating gear of the air conditioner to obtain the target operating parameters.

[0125] Optionally, after the air conditioner determines the operating temperature difference value of the air conditioner running indoor unit, the operating temperature difference value is compared with the second temperature difference threshold value. If the operating temperature difference value is less than the second temperature difference threshold value, the initial expansion valve opening corresponding to the first target temperature difference value is increased according to the preset second opening correction function to obtain the target expansion valve opening, wherein the second temperature difference threshold value is a threshold parameter characterizing the degree to which the inner ring temperature is less than the set temperature. In a specific embodiment, the second temperature difference threshold value is -0.5 degrees Celsius.

[0126] That is, when the operating temperature difference is less than the second temperature difference threshold, the air conditioner performs an opening correction on the initial expansion valve opening of the air conditioner operating indoor unit corresponding to the operating temperature difference, and increases the initial expansion valve opening corresponding to the first target temperature difference according to the preset second opening correction function to obtain the target expansion valve opening. The expression of the second opening correction function is as follows:

[0127] P 目标 =p 初始 +z(P 目标 ≤p max )

[0128] Among them, P 目标 is the target expansion valve opening, p 初始 is the initial expansion valve opening, p max It is the maximum expansion valve opening of the indoor unit of the air conditioner.

[0129] Specifically, after the air conditioner corrects the initial expansion valve opening of each air conditioner running indoor unit, it also obtains each operating temperature difference value updated after the opening correction, and the target temperature difference value in each updated operating temperature difference value. If the target temperature difference value is in the preset target temperature difference interval, the initial expansion valve opening correction is stopped. If the target temperature difference value is not in the preset target temperature difference interval, the initial expansion valve opening correction is continued until the target temperature difference value is in the target temperature difference interval or the target expansion valve is equal to the preset second opening threshold. The second opening threshold is the maximum expansion valve opening of the air conditioner running indoor unit.

[0130] Optionally, if the target expansion valve opening of the air-conditioning indoor unit is equal to a preset second opening threshold, and the target temperature difference value in the operating temperature difference value is less than the first temperature difference threshold, the initial operating gear is lowered according to the preset gear correction strategy to obtain the target operating gear. That is, when the air conditioner determines that the target expansion valve opening of the air-conditioning indoor unit after opening correction is equal to the preset second opening threshold, and the target temperature difference value in the operating temperature difference value is less than the first temperature difference threshold, the air conditioner obtains the initial operating gear of the air-conditioning indoor unit, and when it determines that the initial operating gear is less than the maximum operating gear, it lowers the initial operating gear by one gear according to the gear correction strategy to obtain the target operating gear.

[0131] Specifically, after obtaining the target operating gear and the target expansion valve opening, the air conditioner drives the air conditioner to operate the indoor unit and / or the target outdoor unit according to the target expansion valve opening and the target operating gear, obtains an updated temperature difference value, and adjusts the initial compressor frequency according to the updated temperature difference value to obtain the target compressor frequency. That is, after obtaining the updated temperature difference value, the air conditioner determines whether the updated temperature difference value is in the target temperature difference range. If the updated temperature difference value is not in the target temperature difference range, the initial compressor frequency is further adjusted until the updated temperature difference value is in the target temperature difference range, and the operating compressor frequency of the air conditioner when the updated temperature difference value is in the target operating range is determined as the target compressor frequency.

[0132] Specifically, after obtaining the target compressor frequency, the target expansion valve opening and the target operating gear, the air conditioner determines the target compressor frequency, the target expansion valve opening and / or the target operating gear as the target operating parameter.

[0133] In this embodiment, the air conditioner determines that if the operating temperature difference value is less than the second temperature difference threshold value, then the initial expansion valve opening corresponding to the operating temperature difference value is increased according to the preset second opening correction function to obtain the target expansion valve opening; if the target expansion valve opening is equal to the preset second opening threshold value, and the target temperature difference value in the operating temperature difference value is less than the first temperature difference threshold value, then the initial operating gear is lowered according to the preset gear correction strategy to obtain the target operating gear; the air conditioner operating indoor unit and / or the target outdoor unit are driven to operate according to the target expansion valve opening and the target operating gear to obtain an updated temperature difference value, and the initial compressor frequency is adjusted according to the updated temperature difference value to obtain the target compressor frequency; the target compressor frequency, the target expansion valve opening and / or the target operating gear are determined as the target operating parameters. The operating parameters in the air conditioner are corrected by the difference between the inner ring temperature and the set temperature in the operating area, the control logic of multiple air conditioners is optimized, and the operating stability of one-to-many air conditioners is improved.
