DETAILED DESCRIPTION

[0047] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0048] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are intended to fall within the scope of protection of the present invention.

[0049] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0050] In addition, the terms "first", "second", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0051] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0052] like Figure 1 Figure 2 shows a schematic diagram of the structure of a common air conditioner 01, which includes an indoor unit 10 and an outdoor unit 20. The indoor unit 10 and the outdoor unit 20 are connected by pipelines to transmit refrigerant. The indoor unit 10 includes an indoor heat exchanger 101 and an indoor fan 102. The outdoor unit 20 includes a compressor 201, a four-way valve 202, an outdoor heat exchanger 203, an outdoor fan 204, and an expansion valve 205. The compressor 201, the outdoor heat exchanger 203, the expansion valve 205, and the indoor heat exchanger 101, connected in sequence, form a refrigerant circuit. The refrigerant circulates in the refrigerant circuit, exchanging heat with the air through the outdoor heat exchanger 203 and the indoor heat exchanger 101, respectively, to achieve cooling mode or heating mode of the air conditioner 01.

[0053] The compressor 201 is used to compress the refrigerant so that the low-pressure refrigerant is compressed to form a high-pressure refrigerant.

[0054] Outdoor heat exchanger 203 is used to exchange heat between outdoor air and the refrigerant flowing through outdoor heat exchanger 203. For example, in cooling mode of air conditioner 01, outdoor heat exchanger 203 operates as a condenser, causing the refrigerant compressed by compressor 201 to condense by dissipating heat to the outdoor air through outdoor heat exchanger 203. In heating mode of air conditioner 01, outdoor heat exchanger 203 operates as an evaporator, causing the decompressed refrigerant to absorb heat from the outdoor air through outdoor heat exchanger 203 and evaporate.

[0055] The outdoor fan 204 is used to draw outdoor air into the air-conditioning outdoor unit 20 through the outdoor air inlet of the air-conditioning outdoor unit 20, and send the outdoor air after heat exchange with the outdoor heat exchanger 203 out through the outdoor air outlet of the air-conditioning outdoor unit 20. The outdoor fan 204 provides power for the flow of outdoor air.

[0056] The expansion valve 205 is connected between the outdoor heat exchanger 203 and the indoor heat exchanger 101. The opening of the expansion valve 205 regulates the pressure of the refrigerant flowing through the outdoor heat exchanger 203 and the indoor heat exchanger 101, thereby adjusting the refrigerant flow rate between the outdoor heat exchanger 203 and the indoor heat exchanger 101. The flow rate and pressure of the refrigerant flowing between the outdoor heat exchanger 203 and the indoor heat exchanger 101 will affect the heat exchange performance of the outdoor heat exchanger 203 and the indoor heat exchanger 101. The expansion valve 205 can be an electronic valve. The opening of the expansion valve 205 is adjustable to control the flow rate and pressure of the refrigerant flowing through the expansion valve 205.

[0057] The four-way valve 202 is connected to the refrigerant circuit and is used to switch the flow direction of the refrigerant in the refrigerant circuit so that the air conditioner 01 can perform cooling mode or heating mode.

[0058] The indoor heat exchanger 101 is used to exchange heat between indoor air and the refrigerant flowing through the indoor heat exchanger 101. For example, in the cooling mode of the air conditioner 01, the indoor heat exchanger 101 operates as an evaporator, causing the refrigerant, after dissipating heat through the outdoor heat exchanger 203, to absorb heat from the indoor air through the indoor heat exchanger 101 and evaporate. In the heating mode of the air conditioner 01, the indoor heat exchanger 101 operates as a condenser, causing the refrigerant, after absorbing heat through the outdoor heat exchanger 203, to dissipate heat to the indoor air through the indoor heat exchanger 101 and condense.

[0059] The indoor fan 102 is used to draw indoor air into the air conditioner indoor unit 10 through the indoor air inlet of the air conditioner indoor unit 10, and send the indoor air after heat exchange with the indoor heat exchanger 101 out through the indoor air outlet of the air conditioner indoor unit 10. The indoor fan 102 provides power for the flow of indoor air.

[0060] Air conditioner 01 also includes a controller 30. This controller is used to control the operation of compressor 201. It also controls the opening of expansion valve 205, the speed of outdoor fan 204, and the speed of indoor fan 102. Controller 30 is connected to compressor 201, expansion valve 205, outdoor fan 204, and indoor fan 102 via data cables for communication.

[0061] The controller 30 includes a processor. The processor may include a central processing unit (CPU), a microprocessor, or an application specific integrated circuit (ASIC), and may be configured to perform the corresponding operations described in the controller 30 when the processor executes a program stored in a non-transitory computer-readable medium coupled to the controller 30. The non-transitory computer-readable storage medium may include a magnetic storage device (e.g., a hard disk, a floppy disk, or a magnetic tape), a smart card, or a flash memory device (e.g., an erasable programmable read-only memory (EPROM), a card, a stick, or a keyboard drive).

[0062] When a temperature sensor is provided in the air conditioner 01 , the controller 30 is further configured to obtain the temperature measured by the temperature sensor and control various structures of the air conditioner 01 according to the obtained temperature value.

[0063] Air conditioners are becoming increasingly common, becoming an indispensable appliance in our daily lives. Summer is particularly peak season for air conditioning use. Under current energy conservation and emission reduction policies, reducing the energy consumption of air conditioners at the source is crucial. How to maintain energy-saving features while minimizing the impact on air conditioner performance and ensuring user comfort is a pressing challenge in air conditioning technology.

[0064] Based on the above situation, the embodiments of this specification provide an air conditioner current control method, device, air conditioner and storage medium, which can effectively alleviate the above technical problems.

[0065] An embodiment of the present invention provides an air conditioner current control method, the method comprising: Figure 2 The following steps are shown:

[0066] Step S110: obtaining the current parameter of the air conditioner, and obtaining the temperature change value of the first inner ring temperature within a first preset time period.

[0067] Step S120: Determine the magnitude relationship between the temperature change value and a preset change value to obtain a determination result.

[0068] Step S130: Based on the determination result, adjusting the current parameter according to a preset current control strategy.

[0069] Step S140: controlling the air conditioner to operate according to the adjusted current parameters.

[0070] In step S110 , the current parameter of the air conditioner is obtained, and the temperature change value of the first inner loop temperature within a first preset time period is obtained.

[0071] The current parameter can be the system current of the air conditioner when it is running, and the first inner loop temperature can be the indoor ambient temperature obtained when the air conditioner is running. When the air conditioner is in normal cooling operation, the current parameter of the air conditioner is first obtained, and then the first inner loop temperature is obtained through a sensing device such as a temperature sensor. The first inner loop temperature is obtained again after a first preset time, thereby calculating the temperature change value of the air conditioner within the first preset time. For example, when the air conditioner starts running, the first inner loop temperature is obtained as 30°C. After the first preset time of 5 minutes, the first inner loop temperature is obtained again and is 27°C. In this case, the temperature change value is 3°C.

[0072] Step S120 is executed to determine the magnitude relationship between the temperature change value and the preset change value to obtain a determination result.

[0073] The preset change value can be a pre-set temperature value determined by the developer based on experience or multiple tests. In step S120, after calculating the temperature change value, the temperature change value can be compared with the preset change value to obtain a judgment result. For example, if the temperature change value is 5°C and the preset change value is 2°C, the judgment result is that the temperature change value is greater than the preset change value.

[0074] Step S130 is executed to adjust the current parameter according to a preset current control strategy based on the determination result.

[0075] In an optional embodiment, different preset current control strategies can be set for different judgment results, and then the current parameters of the air conditioner can be adjusted based on the judgment results. For example, if the judgment results can be three types: the temperature change value is greater than the preset change value, the temperature change value is equal to the preset change value, and the temperature change value is less than the preset change value, then three different preset current control strategies can be set for the three judgment results.

[0076] The relationship between the temperature change value and the preset change value can reflect the air conditioner's ability to regulate the room temperature. The larger the temperature change value, the stronger the air conditioner's ability to regulate the room temperature. Therefore, if the temperature change value is greater than the preset change value, the preset current control strategy can be set to significantly reduce the air conditioner's current parameters; if the temperature change value is less than the preset change value, the preset current control strategy can be set to slightly reduce the air conditioner's current parameters; if the temperature change value is equal to the preset change value, the preset current control strategy can be set to operate the air conditioner normally according to the current current parameters without making any adjustments.

[0077] Optionally, adjusting the current parameter according to a preset current control strategy based on the judgment result includes:

[0078] The set temperature and the second inner ring temperature of the air conditioner are obtained, where the second inner ring temperature is the currently detected indoor ambient temperature.

[0079] The temperature difference between the set temperature and the second inner ring temperature is calculated.

[0080] The temperature range within which the temperature difference lies is determined.

[0081] The current parameter is adjusted based on the temperature range and the determination result.

[0082] After determining the relationship between the temperature change value and the preset change value, the indoor ambient temperature (i.e., the second inner ring temperature) is re-acquired, and the temperature difference between the temperature set by the user through the terminal device (i.e., the set temperature) and the second inner ring temperature is calculated. Furthermore, the preset temperature range within which this temperature difference falls is determined. The determination result and the temperature range are used together to determine how to adjust the current parameters.

[0083] For example, if the temperature change is less than the preset change, the set temperature is 25°C, the second inner loop temperature is 28°C, and the calculated temperature difference is 3°C. If the preset temperature range is (-∞, 1°C], (1, 3), [3, +∞), then the temperature range is determined to be [3, +∞). The current parameter adjustment is determined based on the judgment result and the temperature range.

[0084] Optionally, adjusting the current parameter based on the temperature range and the judgment result includes:

[0085] If the judgment result is that the temperature change value is greater than or equal to the preset change value and the temperature range is the first temperature range, then after a second preset time, the current value of the air conditioner is controlled to decrease by a first preset ampere.

[0086] The temperature difference is re-detected after a third preset time. If the temperature difference is still within the first temperature range, the current value of the air conditioner is continued to be controlled to decrease by the first preset ampere after the second preset time until the temperature range within which the temperature difference is located is the second temperature range.

[0087] If the temperature change value is greater than or equal to the preset change value, indicating that the current air conditioner has a strong ability to regulate the room temperature, and the temperature range is determined to be within the first temperature range, the air conditioner can be controlled to maintain the current operating state for a second preset time period. If the temperature range has not changed, the air conditioner current value is controlled to decrease by a first preset ampere. After a third preset time period, the temperature range within which the temperature difference value falls is determined again. If the temperature difference value is still within the first temperature range, the air conditioner current value is further reduced by the first preset ampere until the temperature difference value falls within the second temperature range.

[0088] For example, if the first temperature range is less than or equal to 1°C, the second temperature range is greater than 1°C and less than 2°C, the second preset time is 1 minute, the third preset time is 10 minutes, and the first preset ampere is 8% of the current parameter, the current parameter is 5A. If the temperature difference is within the first temperature range and remains within it for 1 minute, the air conditioner's current value is adjusted from 5A to 4.6A. If, after 10 minutes, the temperature difference is still within the first temperature range, the air conditioner's current value is adjusted from 4.6A to 4.2A. After 10 minutes, the temperature difference is continuously tested in the same temperature range until the temperature difference is within the second temperature range.

[0089] Optionally, if the temperature range is the first temperature range, when the current value of the air conditioner drops to a first lower limit current, the current value of the air conditioner is no longer adjusted.

[0090] If the temperature difference remains within the first temperature range during the adjustment process, the air conditioner current will no longer be adjusted after the air conditioner current drops to the first lower current limit, so that the air conditioner maintains operation at the first lower current limit.

[0091] Optionally, adjusting the current parameter based on the temperature range and the judgment result further includes:

[0092] If the temperature difference falls within the second temperature range, then after the second preset time period, the current value of the air conditioner is controlled to decrease by a second preset ampere.

[0093] The temperature difference is re-detected after the third preset time. If the temperature difference is still within the second temperature range, the current value of the air conditioner is continued to be controlled to decrease by the second preset ampere after the second preset time until the temperature range within which the temperature difference is located is the third temperature range.

[0094] When the temperature difference falls within the second temperature range and remains within the second preset time period, the air conditioner current may be controlled to decrease by a second preset ampere. After a third preset time period, the temperature difference is again determined to be within the second temperature range. If the temperature difference remains within the second temperature range, the air conditioner current may be further decreased by the second preset ampere until the temperature difference falls within the third temperature range.

[0095] For example, if the second temperature range is greater than 1°C and less than 3°C, the third temperature range is greater than or equal to 3°C and less than or equal to 5°C, the second preset time is 2 minutes, the third preset time is 5 minutes, and the second preset ampere is 5% of the current parameter, which is 4A. If the temperature difference is within the second temperature range and remains within it for 2 minutes, the air conditioner's current value is adjusted from 5A to 3.8A. If, after 5 minutes, the temperature difference is still within the second temperature range, the air conditioner's current value is adjusted from 3.8A to 3.6A. After 5 minutes, the temperature difference is continuously tested in the same temperature range until the temperature difference is within the third temperature range.

[0096] Optionally, if the temperature range is the second temperature range, when the current value of the air conditioner drops to a second lower limit current, the current value of the air conditioner is no longer adjusted.

[0097] If the temperature difference remains within the second temperature range during the adjustment process, the air conditioner current will no longer be adjusted after the air conditioner current drops to the second lower current limit, and the air conditioner will maintain operation at the second lower current limit.

[0098] Optionally, adjusting the current parameter based on the temperature range and the judgment result further includes:

[0099] If the temperature difference is within the third temperature range and is maintained for the second preset time period, the air conditioner is controlled to maintain the current value.

[0100] If the temperature difference is within a fourth temperature range and is maintained for the second preset time period, the current value of the air conditioner is controlled to be adjusted to an initial current value for operation.

[0101] When the temperature difference is in the third temperature range and maintained for the second preset time, the air conditioner is controlled to maintain the current current parameters; if the temperature difference is in the fourth temperature range and maintained for the second preset time, the air conditioner is controlled to return to the initial current value set by the system.

[0102] Optionally, adjusting the current parameter based on the temperature range and the judgment result further includes:

[0103] If the judgment result is that the temperature change value is less than the preset change value, the first preset ampere is replaced with the third preset ampere, and the second preset ampere is replaced with the fourth preset ampere; the first lower limit current is replaced with the third lower limit current, and the second lower limit current is replaced with the fourth lower limit current.

[0104] The first preset ampere is greater than the third preset ampere, the second preset ampere is greater than the fourth preset ampere, the first lower limit current is less than the third lower limit current, and the second lower limit current is less than the fourth lower limit current.

[0105] The current parameter of the air conditioner is controlled based on the third preset ampere, the fourth preset ampere, the third lower limit current, and the fourth lower limit current.

[0106] If the temperature change is less than the preset change, the air conditioner's room temperature regulation capability is weak. Therefore, a smaller adjustment range can be used when adjusting the air conditioner current parameter. Accordingly, the lower limit of the air conditioner current parameter can also be lowered, thereby ensuring the minimum operating performance of the air conditioner using a smaller lower limit current.

[0107] Step S140 is executed to control the air conditioner to operate according to the adjusted current parameters.

[0108] After the current parameter adjustment of the air conditioner is completed, the air conditioner is controlled to operate according to the adjusted current parameters.

[0109] In order to better explain the solution of this application, the present specification also provides the following examples: Figure 3 The flowchart shown is used to illustrate this solution.

[0110] like Figure 3 First, the air conditioner current parameter i and the temperature change value △T0 are obtained, and it is determined whether △T0 is greater than or equal to the preset change value T1. If the judgment result is yes, the air conditioner current parameter is controlled using the first preset ampere, the second preset ampere, the first lower limit current, and the second lower limit current set of ① preset values; if the judgment result is no, the air conditioner current parameter is controlled using the third preset ampere, the fourth preset ampere, the third lower limit current, and the fourth lower limit current set of ② preset values.

[0111] The temperature difference △T1 between the set temperature and the currently detected second inner ring temperature is calculated, and it is determined whether △T1 is in the first temperature range (-∞, T3] and reaches the second preset time t1. If so, the current parameter i is controlled to decrease by the first preset ampere / the third preset ampere A1, and the temperature range in which the temperature difference △T1 is located is re-determined after the third preset time t2 until △T1 is in the second temperature range (T3, T4]. If the current parameter i reaches the first lower limit current / the third lower limit current i1min during the adjustment process, the air conditioner is kept running for i1min.

[0112] If △T1 is within the second temperature range (T3, T4) and reaches the second preset time t1, the current parameter i is controlled to decrease by the second preset ampere / fourth preset ampere A2, and the temperature range within which the temperature difference △T1 is located is re-determined after the third preset time t2, until △T1 is within the third temperature range (T4, T5). If the current parameter i reaches the second lower current limit / fourth lower current limit i2min during the adjustment process, the air conditioner is kept running for i2min.

[0113] If ΔT1 is within the third temperature range (T4, T5) and reaches the second preset time t1, the air conditioner is controlled to maintain the current parameter i.

[0114] If ΔT1 is within the fourth temperature range (T5, +∞] and reaches the second preset time t1, the air conditioner is controlled to maintain the initial current parameter i initial operation.

[0115] Based on the same inventive concept, Figure 4 As shown, the embodiment of the present invention provides an air conditioner current control device 300, and the air conditioner current control device 300 includes:

[0116] The data acquisition unit 301 is used to acquire the current parameters of the air conditioner and the temperature change value of the first inner ring temperature within a first preset time period.
