[0035] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0037] The operating principle of the air conditioner involved in the embodiments of this application is described in detail below:

[0038] like Figure 1As shown, the compressor compresses the refrigerant and delivers it through pipes to the condenser. The high-temperature, high-pressure gaseous refrigerant releases heat in the condenser, transforming into a medium-temperature, high-pressure liquid refrigerant. Then, the medium-temperature, high-pressure liquid refrigerant is depressurized through a capillary tube (throttling unit) to become a low-temperature, low-pressure liquid refrigerant. This low-temperature, low-pressure liquid refrigerant is then delivered to the evaporator, where it evaporates into a gas, absorbing a large amount of heat during the evaporation process. Finally, the low-temperature, low-pressure gaseous refrigerant in the evaporator is delivered to the compressor to participate in the next cycle. When the air conditioner is cooling, the outdoor unit's heat exchanger acts as the condenser, and the indoor unit's heat exchanger acts as the evaporator; conversely, when the air conditioner is heating, the outdoor unit's heat exchanger acts as the evaporator, and the indoor unit's heat exchanger acts as the condenser.

[0039] To address the technical problem in related technologies where the energy-saving mode operation is singular and cannot simultaneously consider energy consumption and cooling / heating effects, the energy-saving control method for air conditioners provided in this application determines the energy-saving coefficient based on the difference between the set temperature and the ambient temperature, calculates a target reference value based on the energy-saving coefficient and the average operating current, and then compares the target reference value with a minimum energy-saving current value. If the target reference value is greater than the minimum energy-saving current value, the air conditioner is controlled to operate according to the energy-saving control strategy. In this way, the air conditioner can adjust the energy-saving coefficient according to changes in the indoor ambient temperature and control the operation of the energy-saving mode based on the energy-saving coefficient, enabling the air conditioner to simultaneously consider energy consumption and cooling / heating effects, achieving energy-saving goals while ensuring a good user experience.

[0040] The energy-saving control method for air conditioners provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0041] like Figure 2 As shown in the embodiment of this application, an energy-saving control method for an air conditioner is provided, which may include the following steps 201 and 202:

[0042] Step 201: When the air conditioner is in energy-saving mode, obtain the energy-saving coefficient and the average operating current, and determine the target reference value based on the energy-saving coefficient and the average operating current.

[0043] The energy-saving coefficient is determined based on the difference between the set temperature and the indoor ambient temperature.

[0044] For example, the energy-saving control method provided in this application embodiment can be executed after the air conditioner is triggered to enter energy-saving mode. Users can control the air conditioner to operate in energy-saving mode through an air conditioner remote control or an application (app).

[0045] For example, in order to determine whether it is necessary to limit the operating current of the air conditioner, and the range of the operating current limit, it is first necessary to obtain the energy-saving coefficient and average operating current of the air conditioner, and then make judgments and calculations based on the obtained energy-saving coefficient and average operating current.

[0046] Specifically, the step of obtaining the energy-saving coefficient in step 201 above may include the following steps 201a1 and 201a2:

[0047] Step 201a1: Obtain the set temperature of the air conditioner and the indoor ambient temperature of the area where the air conditioner is located, and calculate the target temperature difference between the set temperature and the indoor ambient temperature.

[0048] Step 201a2: Determine the energy-saving coefficient based on the target temperature difference.

[0049] The energy-saving coefficient is positively correlated with the target temperature difference.

[0050] For example, such as Figure 3 As shown, before determining whether to implement an energy-saving control strategy, it is first necessary to obtain the air conditioner's set temperature T0 and the current indoor ambient temperature T1, and calculate the difference ΔT between the set temperature T0 and the current indoor ambient temperature T1 (i.e., the target temperature difference mentioned above). Then, based on this difference ΔT, the energy-saving coefficient is determined. For example, when ΔT ≥ 4℃, an 80% energy-saving control strategy is implemented, i.e., the energy-saving coefficient a = 0.8; when 4℃ > ΔT ≥ 2℃, a 60% energy-saving control strategy is implemented, i.e., the energy-saving coefficient a = 0.6; when 2℃ > ΔT, a 40% energy-saving control strategy is implemented, i.e., the energy-saving coefficient a = 0.4.

[0051] For example, the energy-saving coefficient mentioned above is mainly used to determine the operating current of the air conditioner in energy-saving mode. The higher the energy-saving coefficient, the greater the operating current of the air conditioner in energy-saving mode.

[0052] Specifically, the step of obtaining the average current in step 201 above may include the following steps: 201b1 value step 201b3:

[0053] Step 201b1: Obtain the first current set.

[0054] The first current set includes current values ​​recorded at multiple times.

[0055] Step 201b2: Sequentially remove the extreme values ​​of the current in the first current set until the mean square error of the multiple current values ​​contained in the first current set is less than a preset threshold.

[0056] The current extreme values ​​include: maximum value and minimum value.

[0057] Step 201b3: Calculate the average value of the multiple current values ​​contained in the first current set to obtain the average operating current.

[0058] For example, in order to obtain the average current of the air conditioner, it is necessary to collect the operating current of the air conditioner at multiple time points to obtain the aforementioned first current set. For instance, the operating current of the air conditioner can be collected at 1-minute intervals over 1 hour, and the average operating current of the air conditioner over 1 hour can be calculated.

[0059] For example, since the current of an air conditioner may fluctuate during operation, in order to improve the accuracy of the average operating current, it is necessary to determine the dispersion of the current data contained in the first current set by using the mean square error of the multiple current values ​​included in the first current set. If the dispersion of the current data contained in the first current set is high (mean square error greater than or equal to the aforementioned preset threshold), the dispersion of the current data contained in the first current set can be reduced by removing the current extreme values ​​in the first current set until its mean square error is less than the preset threshold.

[0060] It should be noted that when removing current extreme values ​​from the first current set each time, you can remove one maximum value or one minimum value individually, or you can remove one maximum value and one minimum value at the same time.

[0061] Furthermore, when calculating the average operating current, weights can be assigned to each current value based on the recording time of each current value in the second current set, and a weighted calculation can be performed on each current value in the second current set.

[0062] Specifically, step 201b3 above may also include the following step 201b31:

[0063] Step 201b31: Based on the weight corresponding to each current value in the second current set, calculate the weighted average of the multiple current values ​​contained in the second current set to obtain the average operating current.

[0064] Among them, the closer the recording time is to the current time, the greater the weight of the current value.

[0065] It is understandable that current values ​​closer to the current time are better able to reflect the current operating status, and therefore, their weight is greater than that of current values ​​farther away from the current time.

[0066] For example, after obtaining the energy-saving coefficient and average operating current, a target reference value can be calculated based on the energy-saving coefficient and average operating current, and a decision can be made based on the target reference value to determine whether an energy-saving control strategy needs to be implemented.

[0067] Specifically, step 201 above may also include the following steps 201c1 and 201c2:

[0068] Step 201c1: Calculate the product of the energy-saving coefficient and the average operating current to obtain a first reference value, and calculate the difference between the first reference value and the preset current adjustment value to obtain a second reference value.

[0069] Step 201c2: Determine the second reference value as the target reference value.

[0070] For example, after obtaining the energy-saving coefficient and the average operating current, a simple mathematical operation needs to be performed based on the energy-saving coefficient and the average operating current to obtain the first reference value and the second reference value, wherein the second reference value is less than the first reference value.

[0071] For example, the first reference value and the second reference value are used to limit the operating current of the air conditioner in subsequent steps, and the second reference value is also used to determine whether to implement an energy-saving control strategy.

[0072] For example, such as Figure 3 As shown, after obtaining the energy-saving coefficient a and the operating current c, we can calculate a*c=b1 (i.e. the first reference value mentioned above) and b1-0.5=b2 (i.e. the second reference value mentioned above).

[0073] Step 202: If the target reference value is greater than the minimum energy-saving current value corresponding to the air conditioner, control the air conditioner to operate according to the energy-saving control strategy.

[0074] The energy-saving control strategy is used to limit the operating current of the air conditioner.

[0075] For example, if the target reference value is greater than the minimum energy-saving current value corresponding to the air conditioner, it can be determined that the operating current of the air conditioner can be further reduced. At this time, the air conditioner can be controlled to implement an energy-saving control strategy.

[0076] Specifically, the step of implementing the energy-saving control strategy in step 202 above may include the following steps 202a1 and 202a2:

[0077] Step 202a1: Limit the operating current of the air conditioner between the first reference value and the second reference value, and control the air conditioner to run for a first preset time.

[0078] Step 202a2: Remove the restriction on the operating current of the air conditioner, and control the air conditioner to run for a second preset duration according to the operating mode before the operating current was restricted.

[0079] For example, such as Figure 3As shown, when b2 > A (i.e., the minimum energy-saving current mentioned above), the air conditioner is controlled to implement an energy-saving limiting strategy, that is, the operating current is limited to [b2, b1], and it runs continuously for 20 to 60 minutes (i.e., the first preset duration mentioned above); after that, the operating current limit is lifted, and it runs continuously for 5 to 10 minutes (i.e., the second preset duration mentioned above).

[0080] For example, during the process of limiting the operating current of the air conditioner, the operating current is not recorded. Therefore, in order for the air conditioner to accurately calculate the energy-saving coefficient in the next stage, after limiting the operating current, it is necessary to remove the operating current limit and continue to run for a second preset time so that the air conditioner can restore all operating parameters to normal and record the operating current to facilitate the calculation of the energy-saving coefficient in the subsequent process.

[0081] Optionally, in this embodiment of the application, the minimum energy-saving current value can be determined based on the actual capacity of the air conditioner.

[0082] For example, prior to step 202 above, the energy-saving control method for air conditioners provided in this application embodiment may further include the following step 203:

[0083] Step 203: Obtain the maximum operating power of the air conditioner, and determine the minimum energy-saving current value of the air conditioner based on the maximum operating power.

[0084] The minimum energy-saving current value is positively correlated with the maximum operating power of the air conditioner.

[0085] Understandably, the greater the cooling capacity (maximum operating power) of an air conditioner, the greater the minimum operating current required for its compressor. When the compressor's operating current is less than this minimum operating current, the compressor will not function properly. Therefore, the minimum operating current of the air conditioner needs to be set based on its maximum operating power, which is the aforementioned minimum energy-saving current value. When the air conditioner is running in energy-saving mode, its operating current cannot be lower than this minimum energy-saving current value.

[0086] Optionally, in the embodiments of this application, when it is determined that the target reference value is less than or equal to the minimum energy-saving current value, the energy-saving control strategy may not be executed.

[0087] For example, after step 201 above, the energy-saving control method for air conditioners provided in this application embodiment may further include the following step 204:

[0088] Step 204: If the target reference value is less than or equal to the minimum energy-saving current value corresponding to the air conditioner, output a target reminder message and exit the energy-saving mode.

[0089] The target reminder information is used to indicate that the air conditioner is in its most energy-efficient state.

[0090] For example, such as Figure 3 As shown, when b2≤A, the air conditioner can output "Already in the most energy-efficient state" (i.e. the target reminder information mentioned above) to remind the user that it is currently in the most energy-efficient state.

[0091] For example, after outputting the target reminder information, the air conditioner may exit the energy-saving mode or not, and determine the relationship between the target reference value and the minimum energy-saving current value according to a preset cycle.

[0092] The energy-saving control method for air conditioners provided in this application first obtains an energy-saving coefficient and an average operating current when the air conditioner is in energy-saving mode, and determines a target reference value based on the energy-saving coefficient and the average operating current. Then, if the target reference value is greater than the minimum energy-saving current value corresponding to the air conditioner, the air conditioner is controlled to operate according to an energy-saving control strategy. The energy-saving coefficient is determined based on the difference between the set temperature and the indoor ambient temperature; the energy-saving control strategy is used to limit the operating current of the air conditioner. In this way, while reducing energy consumption, the user's cooling and heating needs are fully considered, simultaneously balancing energy consumption and user experience.

[0093] It should be noted that the energy-saving control method for air conditioners provided in this application embodiment can be executed by an energy-saving control device for air conditioners, or by a control module within that energy-saving control device for executing the energy-saving control method for air conditioners. This application embodiment uses the example of an energy-saving control device for air conditioners executing the energy-saving control method for air conditioners to illustrate the energy-saving control device for air conditioners provided in this application embodiment.
