Description

Technical Field

[0001] This invention relates to the field of air conditioner technology, and in particular to a method for displaying energy-saving features of an air conditioner, an operation control device, and an air conditioner. Background Technology

[0002] With the development of air conditioner technology, the energy-saving capability of air conditioners has gradually become a concern for users. To meet users' energy-saving needs, current air conditioners all have energy-saving modes. Although air conditioners offer energy-saving modes, users cannot check in real time whether the air conditioner is running in energy-saving mode or how much electricity it can save when running in energy-saving mode, resulting in a lack of real-time perception of the air conditioner's energy-saving effect. Summary of the Invention

[0003] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a method for displaying the power saving of an air conditioner, an operation control device and an air conditioner, which can simplify the operation path for users to know the power saving of the air conditioner and make it convenient for users to perceive the energy saving effect of the air conditioner in real time.

[0004] In a first aspect, embodiments of the present invention provide a method for displaying energy-saving information in an air conditioner, wherein the display panel of the air conditioner is provided with an energy-saving indicator light, and the method includes:

[0005] When the air conditioner is running in energy-saving mode, the power-saving indicator light is controlled to display a running light pattern to indicate that the air conditioner is performing power-saving statistics;

[0006] When the air conditioner exits the energy-saving mode, the power-saving indicator light exits the sequential light mode and displays the first lighting mode to indicate the power saving of the air conditioner in the energy-saving mode.

[0007] The air conditioner power saving display method provided by the embodiments of the present invention has at least the following beneficial effects: When the air conditioner is in energy-saving mode, the air conditioner controls the power saving indicator light to display in a running light pattern to indicate that the air conditioner is performing power saving statistics. Thus, when the user sees the power saving indicator light on the air conditioner's display panel displaying in a running light pattern, they can know that the air conditioner is operating in energy-saving mode. When the air conditioner exits energy-saving mode, the air conditioner controls the power saving indicator light to exit the running light pattern and display in a first-light pattern to indicate the power saving in energy-saving mode. Thus, when the user sees the power saving indicator light on the air conditioner's display panel displaying in the first-light pattern, they can know how much power the air conditioner has saved in energy-saving mode. In this way, the user can know whether the air conditioner is operating in energy-saving mode and the power saved when the air conditioner is operating in energy-saving mode without performing overly cumbersome and complex operations, thereby simplifying the user's operation path to know the air conditioner's power saving and enabling the user to conveniently perceive the energy-saving effect of the air conditioner in real time.

[0010] Control the power saving indicator light to exit the continuous light mode and display the first lighting mode in the target gear indicator area to indicate power saving.

[0075] This section will describe in detail specific embodiments of the present invention. Preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention.

[0076] In the description of this invention, "several" means one or more, "multiple" means two or more, "greater than," "less than," "exceeding," etc. are understood to exclude the number itself, while "above," "below," "within," etc. are understood to include the number itself. "Any one" refers to one or more, and "at least one of the following" and similar expressions refer to any combination of these items, including any combination of single or multiple items. If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of indicated technical features or the order of the indicated technical features.

[0077] It should be noted that the terms "setting," "installing," and "connecting" in the embodiments of this invention should be interpreted broadly. Those skilled in the art can reasonably determine the specific meaning of the above terms in the embodiments of this invention in conjunction with the specific content of the technical solution. For example, the term "connection" can be a mechanical connection, an electrical connection, or a connection that allows for mutual communication; it can be a direct connection or an indirect connection through an intermediate medium.

[0078] It should be noted that the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0079] Currently, to meet users' energy-saving needs for air conditioners, an energy-saving mode has been added to the existing standard mode. While air conditioners operating in energy-saving mode can effectively reduce electricity consumption, most users lack a direct understanding of the energy-saving capabilities. They typically rely on smart meters or home energy management systems to check past months' electricity consumption and bills, comparing them to the current month's usage to determine the effectiveness of energy savings. However, when an air conditioner is running in energy-saving mode, users cannot directly monitor whether it is truly in this mode or how much electricity is being saved, resulting in a lack of real-time perception of the air conditioner's energy-saving performance.

[0080] To simplify the user's process of knowing whether an air conditioner is saving energy and to facilitate real-time perception of its energy-saving effect, this invention provides a method for displaying air conditioner energy saving. When the air conditioner is in energy-saving mode, the energy-saving indicator light will display in a sequential light pattern to indicate that the air conditioner is performing energy-saving statistics. Thus, when the user sees the energy-saving indicator light on the air conditioner's display panel in the sequential light pattern, they know that the air conditioner is operating in energy-saving mode. When the air conditioner exits energy-saving mode, the energy-saving indicator light will exit the sequential light pattern and display in the first illuminated mode to indicate the energy saved during energy-saving mode. Thus, when the user sees the energy-saving indicator light on the air conditioner's display panel in the first illuminated mode, they know how much energy the air conditioner has saved in energy-saving mode. In this way, users can know whether the air conditioner is operating in energy-saving mode and the energy saved when the air conditioner is operating in energy-saving mode without going through an overly cumbersome process, achieving the goal of simplifying the user's process of knowing whether the air conditioner is saving energy and thus facilitating real-time perception of the air conditioner's energy-saving effect.

[0081] Reference Figure 1 As shown, Figure 1 This is a flowchart of a power saving display method for an air conditioner provided by an embodiment of the present invention. The display method includes, but is not limited to, steps S100 to S200.

[0082] Step S100: When the air conditioner is running in energy-saving mode, the power-saving indicator light is set to a running light pattern to indicate that the air conditioner is performing power-saving statistics.

[0083] Step S200: When the air conditioner exits the energy-saving mode, the power-saving indicator light exits the sequential light mode and displays the first illuminated mode to indicate the power saving of the air conditioner in the energy-saving mode.

[0084] In some embodiments, energy-saving mode is an operating mode that saves electricity compared to normal mode. Normal mode refers to the mode in which the air conditioner operates without energy saving. When a user turns on the air conditioner, it operates in normal mode. The air conditioner only switches to energy-saving mode under user control. For example, the air conditioner will only operate in energy-saving mode when the user presses the energy-saving mode button on the air conditioner remote control.

[0085] In some embodiments, the air conditioner's display panel may be equipped with a power-saving indicator light. This indicator light may include multiple LEDs, which can form various shapes, such as the shape of a battery, a tree, etc. That is, the power-saving indicator light can have many different shapes, and this embodiment does not specifically limit this. For example... Figure 2 As shown, the power-saving indicator light 210 can be shaped like a battery. The power-saving indicator light 210 includes multiple LEDs 211 arranged sequentially within the battery outline of the power-saving indicator light 210. When the air conditioner is operating in energy-saving mode, the multiple LEDs 211 inside the power-saving indicator light 210 can display a sequential light pattern, that is, the multiple LEDs 211 light up and turn off in sequence to indicate that the air conditioner is performing power-saving statistics. Thus, when the user sees the power-saving indicator light 210 displaying a sequential light pattern, they can know that the air conditioner is operating in energy-saving mode, thereby simplifying the user's operation.

[0086] In some embodiments, when the power-saving indicator light is in a running light mode, it indicates that the air conditioner is performing power-saving statistics. When the air conditioner exits energy-saving mode, it controls the power-saving indicator light to exit the running light mode and display the first illumination mode based on the statistically obtained power savings, thereby indicating the amount of power saved by the air conditioner in energy-saving mode. Thus, when a user sees the power-saving indicator light on the air conditioner's display panel in the first illumination mode, they can know how much power the air conditioner has saved in energy-saving mode. Therefore, the power-saving display method of this embodiment allows users to know whether the air conditioner is running in energy-saving mode and the amount of power saved when running in energy-saving mode without performing overly cumbersome operations. This simplifies the user's process for knowing the air conditioner's power-saving performance and allows users to perceive the energy-saving effect of the air conditioner in real time.

[0087] In some embodiments, the first lighting mode can be a constant-on mode or a flashing mode, which can be appropriately set according to the actual application situation, and is not specifically limited here. The constant-on mode means that the power-saving indicator light is always on. The flashing mode means that the power-saving indicator light is in a state of alternating on and off, or that the multiple LEDs inside the power-saving indicator light are in a state of alternating on and off sequentially.

[0088] In some embodiments, the power-saving indicator light can have multiple different levels of indicator areas, each corresponding to a different range of power savings. Based on the statistically obtained power savings, the air conditioner can control the power-saving indicator light to display in the first illumination mode in the corresponding level of indicator area, thereby more conveniently indicating the power saved by the air conditioner and allowing users to better perceive the energy-saving effect of the air conditioner in real time.

[0089] In some embodiments, the process of controlling the power-saving indicator light to exit the sequential light mode and display a first lighting mode in step S200 to indicate the power saving of the air conditioner in energy-saving mode may include the following steps: first, determining the target level indicator area for the corresponding level among multiple level indicator areas based on the statistically obtained power saving; then, controlling the power-saving indicator light to exit the sequential light mode and displaying a first lighting mode in the target level indicator area to indicate power saving. For example Figure 3 As shown, assume that the power-saving indicator light 210 has a low-level indicator area 310, a medium-level indicator area 320, and a high-level indicator area 330. When the power saving calculated by the air conditioner is within the power saving range corresponding to the low-level indicator area 310, the air conditioner will control the power-saving indicator light 210 to exit the running light mode and display the first lighting mode in the low-level indicator area 310; when the power saving calculated by the air conditioner is within the power saving range corresponding to the medium-level indicator area 320, the air conditioner will control the power-saving indicator light 210 to exit the running light mode and display the first lighting mode in the medium-level indicator area 320; and so on.

[0090] In some embodiments, in the multiple different levels of the power saving indicator light, a higher-level indicator area includes a lower-level indicator area. For example... Figure 3 As shown, the intermediate gear indicator area 320 includes the low gear indicator area 310, and the high gear indicator area 330 includes the intermediate gear indicator area 320 and the low gear indicator area 310.

[0091] In some embodiments, among the multiple different levels of the power-saving indicator light, a higher level of the indicator light indicates greater energy savings by the air conditioner. For example, assuming the power-saving indicator light has low-level, medium-level, and high-level indicator areas, in one embodiment, the power-saving range corresponding to the low-level indicator area can be less than or equal to 0.5 kWh, the power-saving range corresponding to the medium-level indicator area can be greater than 0.5 kWh to less than or equal to 1 kWh, and the power-saving range corresponding to the high-level indicator area can be greater than 1 kWh. If the power saving calculated by the air conditioner is 0.7 kWh, it can be determined that this power saving falls within the power saving range corresponding to the medium-level indicator area, so the air conditioner can control the power-saving indicator light to display a first lighting mode in the medium-level indicator area. Similarly, if the power saving calculated by the air conditioner is 1.5 kWh, the power-saving indicator light can be controlled to display a first lighting mode in the high-level indicator area.

[0092] It should be noted that the process of the air conditioner performing energy-saving statistics in this embodiment will be described in detail in subsequent embodiments, and will not be described here.

[0093] Reference Figure 4 As shown, Figure 4 This is a flowchart of a power saving display method for an air conditioner provided in another embodiment of the present invention. The display method includes, but is not limited to, step S300.

[0094] Step S300: In response to the touch operation of the energy-saving mode activation control in the air conditioning control application interface, the current power saving of the air conditioner in energy-saving mode is displayed in the air conditioning control application interface, and the new power saving is updated and displayed in the air conditioning control application interface at preset intervals.

[0095] In some embodiments, the air conditioner is equipped with a corresponding air conditioning control application running on the user terminal. When the user clicks to enter the air conditioning control application, the air conditioning control application interface is displayed. This interface includes a control to activate the energy-saving mode. When the user locates and touches the energy-saving mode activation control in the air conditioning control application interface, the air conditioner responds to the user's action, operates in energy-saving mode, and calculates the energy savings during this mode. After completing the energy-saving calculation, the air conditioner can directly send the calculated energy savings to the user terminal, or send the calculated energy savings to the user terminal via a cloud server. Once the user terminal receives the energy savings data, it will display the current energy savings of the air conditioner in energy-saving mode in the air conditioning control application interface.

[0096] In some embodiments, after the user terminal receives power saving data from the air conditioner and displays it in the air conditioner control application interface, it can continue to receive subsequent power saving data sent by the air conditioner, and update the display of new power saving data in the air conditioner control application interface at preset intervals. This allows the user to promptly view the power savings achieved by the air conditioner through the air conditioner control application interface on the user terminal. It should be noted that the preset time can be the period during which the air conditioner calculates power saving data, or the period during which the air conditioner reports power saving statistics to the cloud server, etc. For example, the preset time could be 10 minutes or 15 minutes, etc., and this embodiment does not impose a specific limitation.

[0097] In some embodiments, the air conditioning control application interface also displays a power saving statistics control. In this case, when the user finds and touches the power saving statistics control in the air conditioning control application interface, the air conditioner will respond to the user's touch operation on the power saving statistics control, obtain the historical power saving of the air conditioner, and display the historical power saving in a graphical manner in the air conditioning control application interface. When displaying historical power saving in a graphical manner in the air conditioning control application interface, various different charts such as bar charts or pie charts can be used to display historical power saving.

[0098] In some embodiments, historical power saving data may include daily power saving and monthly power saving. Different graphs may be used to display daily and monthly power saving, or the same graph may be used; this embodiment does not impose a specific limitation. For example, different bar charts may be used to display daily and monthly power saving, or a bar chart may be used to display daily power saving, and a pie chart may be used to display monthly power saving, etc. In this way, users can easily obtain daily and monthly power saving data through simple graphs, thereby simplifying the user's process for understanding the air conditioner's power saving and allowing users to perceive the air conditioner's energy-saving effect in real time.

[0099] In some embodiments, the electricity saved by the air conditioner can be converted into reward points in the air conditioner control application. Each time the electricity saved by the air conditioner is tallied, corresponding points are awarded in the air conditioner control application. The more electricity saved, the more reward points are earned. Furthermore, on the last day of each month, the air conditioner control application can rank users based on their total reward points earned that month, allowing for comparison of the energy-saving performance of air conditioners among different users.

[0100] In some embodiments, the air conditioner control application interface also displays a monthly report control. In this case, when the user finds and touches the monthly report control in the air conditioner control application interface, the air conditioner will respond to the user's touch operation and display a monthly power saving report page. The monthly power saving report page displays the total monthly power saving, the total monthly electricity cost saving, and the target date with the greatest power saving. The total monthly power saving is converted from historical power saving data, the total monthly electricity cost saving is determined based on the total monthly power saving, and the target date is determined based on historical power saving. In this way, users can learn about the monthly power saving and the electricity cost saving through simple report content. This not only simplifies the user's operation path to understand the power saving effect of the air conditioner, but also allows users to easily perceive the energy-saving effect of the air conditioner in real time.

[0101] Reference Figure 5 As shown, Figure 5 This is a flowchart of a method for calculating energy-saving statistics in an air conditioner according to an embodiment of the present invention. This method is the same as the energy-saving display method for any of the preceding embodiments (e.g., the one described earlier). Figure 1 or Figure 4 The method for calculating energy saving statistics for an air conditioner (shown in the air conditioner energy saving display method) may include, but is not limited to, steps S500 to S800.

[0102] Step S500: When the air conditioner is in energy-saving mode, determine the first total power of the air conditioner, the first compressor operating frequency, the first indoor fan speed and the first outdoor temperature;

[0103] Step S600: Predict the operating frequency of the second compressor, the speed of the second indoor fan, and the second outdoor temperature when the air conditioner is in normal mode;

[0104] Step S700: Based on the first difference between the operating frequency of the first compressor and the operating frequency of the second compressor, the second difference between the speed of the first indoor fan and the speed of the second indoor fan, the third difference between the first outdoor temperature and the second outdoor temperature, and the first total power, predict the second total power of the air conditioner in normal mode;

[0105] Step S800: Determine the first power consumption corresponding to the first total power and the second power consumption corresponding to the second total power, and predict the power saving of the energy-saving mode relative to the normal mode based on the first power consumption and the second power consumption.

[0106] In some embodiments, normal mode refers to the mode in which the air conditioner operates in non-energy-saving mode. When a user turns on the air conditioner, it operates in normal mode. The air conditioner only switches to energy-saving mode under user control. For example, the air conditioner will only operate in energy-saving mode when the user presses the energy-saving mode button on the air conditioner remote control.

[0107] In some embodiments, since the air conditioner operates only in energy-saving mode, its various parameters in normal mode are predicted when it operates in energy-saving mode. The first outdoor temperature in energy-saving mode and the second outdoor temperature in normal mode both refer to the outdoor temperature. Therefore, it can be assumed that the first outdoor temperature in energy-saving mode and the second outdoor temperature in normal mode are equal. For example, suppose the first outdoor temperature in energy-saving mode is T. 4_save (k), while the second outdoor temperature under normal mode is T. 4_normal (k), then T can be obtained. 4_save (k)=T 4_normal (k).

[0108] In some embodiments, when the air conditioner is in energy-saving mode, it can be allowed to run for a period of time until it reaches a stable state before determining its first total power, first compressor operating frequency, and first indoor fan speed. This ensures the accuracy of the obtained first total power, first compressor operating frequency, and first indoor fan speed, thereby improving the accuracy of predicting the second total power when the air conditioner is in normal mode, and consequently improving the accuracy of predicting the air conditioner's energy savings. The initial running time can be appropriately selected based on the actual application, such as 1 hour or 0.5 hours, etc., without specific limitations.

[0109] In some embodiments, a stable state for an air conditioner means that the temperature of the space in which the air conditioner is located is stable. For example, if the temperature of the space in which the air conditioner is located at the previous moment is equal to the temperature at the current moment, or the difference between the two is less than or equal to a preset temperature difference, then the air conditioner can be considered to be in a stable state. It should be noted that the preset temperature difference can be appropriately selected according to the actual application, for example, the preset temperature difference can be 1℃ or 0.5℃, etc., and is not specifically limited here.

[0110] In some embodiments, the first total power of the air conditioner in energy-saving mode can be calculated based on the total current and voltage of the air conditioner in energy-saving mode. For example, after the air conditioner reaches a stable state in energy-saving mode, the total current and voltage of the air conditioner can be detected first, and then multiplied by the total current and voltage to obtain the first total power of the air conditioner in energy-saving mode. In addition, the first compressor operating frequency and the first indoor fan speed of the air conditioner in energy-saving mode can be detected by corresponding sensors. The detection process can be referred to the relevant processing procedures in related technologies, and will not be elaborated further here.

[0111] In some embodiments, such as Figure 6 As shown, the operating frequency of the second compressor and the speed of the second indoor fan in normal mode of the air conditioner can be predicted through the following steps S610 to S620:

[0112] Step S610: Predict the second indoor temperature when the air conditioner is in normal mode;

[0113] Step S620: Based on the second indoor temperature, predict the operating frequency of the second compressor and the speed of the second indoor fan when the air conditioner is in normal mode.

[0114] In some embodiments, when predicting the operating frequency of the second compressor and the speed of the second indoor fan in normal mode based on the second indoor temperature, a corresponding preset function or preset model can be invoked to make the prediction. For example, a formula can be invoked. and formula This is used to predict the operating frequency of the second compressor and the speed of the second indoor fan when the air conditioner is in normal mode. In these two formulas, This refers to the predicted second indoor temperature when the air conditioner is in normal mode. This refers to the speed of the second indoor fan when the air conditioner is in normal mode. This refers to the operating frequency of the second compressor when the air conditioner is in normal mode. f1() is a preset function used to calculate the speed of the second indoor fan, and f2() is a preset function used to calculate the operating frequency of the second compressor. Both functions f1() and f2() can be selected or adjusted according to actual application needs; no specific limitations are specified here.

[0115] In some embodiments, such as Figure 7 As shown, the process of predicting the second indoor temperature when the air conditioner is in normal mode may include, but is not limited to, the following steps S611 to S614.

[0116] Step S611: Determine the first heat load of the air conditioner at the previous operating moment in energy-saving mode;

[0117] Step S612: Determine the initial indoor temperature of the air conditioner in normal mode, and predict the second cooling capacity of the air conditioner at the current operating moment in normal mode based on the initial indoor temperature.

[0118] Step S613: Based on the first heat load, predict the second heat load of the air conditioner at the current operating moment in normal mode;

[0119] Step S614: Based on the second cooling capacity and the second heat load, predict the second indoor temperature at the next operating moment of the air conditioner in normal mode.

[0120] In some embodiments, when determining the first heat load of the air conditioner at the previous operating moment in energy-saving mode, the first cooling capacity of the air conditioner at the previous operating moment in energy-saving mode and the first indoor temperature difference from the previous operating moment to the current operating moment can be determined first. Then, the first heat load of the air conditioner at the previous operating moment can be determined based on the first cooling capacity and the first indoor temperature difference. Specifically, in determining the first cooling capacity of the air conditioner at the previous operating moment in energy-saving mode, the first indoor temperature, the first indoor heat exchanger temperature, the first compressor operating frequency, and the first indoor fan speed of the air conditioner at the previous operating moment in energy-saving mode can be obtained first. Then, the first cooling capacity can be determined based on the first indoor temperature, the first indoor heat exchanger temperature, the first compressor operating frequency, and the first indoor fan speed. For example, the first heat load of the air conditioner at the previous operating moment in energy-saving mode can be calculated using the following formula (1):

[0121] Q _save (k-1)=Q[T 1_save (k-1),T 2_save (k-1),Fr _save (k-1),W _save [(k-1)]*1000 (1)

[0122] In formula (1), Q _save (k-1) refers to the first cooling capacity of the air conditioner at the previous operating moment in energy-saving mode, T 1_save (k-1) refers to the first indoor temperature at the previous operating moment of the air conditioner in energy-saving mode, T. 2_save (k-1) refers to the first indoor heat exchanger temperature at the previous operating moment of the air conditioner in energy-saving mode, Fr _save (k-1) refers to the operating frequency of the first compressor at the previous operating moment in energy-saving mode of the air conditioner, W. _save(k-1) refers to the speed of the first indoor fan at the previous operating moment of the air conditioner in energy-saving mode, *1000 indicates unit conversion, and Q() refers to the function for calculating the first cooling capacity. Therefore, when the first indoor temperature, the first indoor heat exchanger temperature, the first compressor operating frequency, and the first indoor fan speed at the previous operating moment of the air conditioner in energy-saving mode are obtained, the first indoor temperature, the first indoor heat exchanger temperature, the first compressor operating frequency, and the first indoor fan speed are input as parameters into formula (1), and the first cooling capacity of the air conditioner at the previous operating moment in energy-saving mode can be calculated.

[0123] In some embodiments, the function Q() can take the following form:

[0124] Q()=(1-k1*(T1-T2-T mean ))*(1-k2*Vol+α)C*ρ*V room (T1-T2)

[0125] Where k1, k2, and α are the correlation coefficients of the function Q(), which can be determined based on empirical information; T1 refers to the temperature of the first indoor unit, T2 refers to the temperature of the heat exchanger in the first indoor unit, and T... mean This refers to the average indoor temperature from the previous operating time to the current operating time; Vol refers to the speed of the first indoor fan; C refers to the specific heat capacity of the air in the space where the air conditioner is located; ρ refers to the air density in the space where the air conditioner is located; V room This refers to the volume of the space where the air conditioner is located. Under normal conditions, C can be 1.005 kJ / kg-k, and ρ can be 1.16 kg / m³, but this embodiment does not impose specific limitations. In other words, in determining the first cooling capacity based on the first indoor temperature, the first indoor heat exchanger temperature, the first compressor operating frequency, and the first indoor fan speed, the volume of the space where the air conditioner is located, the specific heat capacity of the air, and the air density can be obtained first. Then, the first indoor temperature, the first indoor heat exchanger temperature, the average first indoor temperature from the previous operating time to the current operating time, the first compressor operating frequency, the first indoor fan speed, the space volume, the specific heat capacity of the air, and the air density are input as parameters into the function Q(), thus calculating the first cooling capacity of the air conditioner in energy-saving mode at the previous operating time.

[0126] In some embodiments, the formula ΔT can be used. 1_save (k-1)=T 1_save (k-1)-T 1_save (k) Calculate the first indoor temperature difference from the previous operating time to the current operating time, where ΔT 1_save (k-1) refers to the first indoor temperature difference, T 1_save(k-1) refers to the first indoor temperature at the previous operating time, T 1_save (k) refers to the first indoor temperature at the current operating moment.

[0127] In some embodiments, after calculating the first cooling capacity and the first indoor temperature difference of the air conditioner in energy-saving mode at the previous operating time, the first heat load of the air conditioner at the previous operating time can be determined by the following formula (2):

[0128]

[0129] In formula (2), This refers to the first heat load of the air conditioner at the previous operating moment; Q _save (k-1) refers to the initial cooling capacity of the air conditioner at the previous operating moment; dt refers to the energy-saving prediction update cycle of the air conditioner in energy-saving mode; ΔT 1_save (k-1) refers to the first indoor temperature difference from the previous operating time to the current operating time; C refers to the specific heat capacity of the air in the space where the air conditioner is located; ρ refers to the air density in the space where the air conditioner is located; V room *1000 indicates the volume of the space where the air conditioner is located. In some embodiments, the value of dt can be 60 seconds, but this embodiment does not specify a value. Therefore, after obtaining the first cooling capacity and the first indoor temperature difference, and determining the power saving prediction update cycle, the first cooling capacity, the first indoor temperature difference, and the power saving prediction update cycle are input into formula (2) as input parameters to calculate the first heat load of the air conditioner at the previous operating moment.

[0130] In some embodiments, such as Figure 8 As shown, the process of predicting the second cooling capacity of the air conditioner at the current operating moment in normal mode based on the initial indoor temperature may include, but is not limited to, the following steps S6121 to S6124.

[0131] Step S6121: Based on the initial indoor temperature, predict the third indoor temperature at the current operating moment of the air conditioner in normal mode;

[0132] Step S6122: Based on the third indoor temperature, predict the operating frequency of the third compressor and the speed of the third indoor fan at the current operating moment in normal mode of the air conditioner;

[0133] Step S6123: Based on the third indoor temperature, the third compressor operating frequency, and the third indoor fan speed, predict the temperature of the third indoor heat exchanger at the current operating moment in normal mode.

[0134] Step S6124: Based on the temperature of the third indoor heat exchanger, the temperature of the third indoor unit, the operating frequency of the third compressor, and the speed of the third indoor fan, predict the second cooling capacity of the air conditioner at the current operating moment in normal mode.

[0135] In some embodiments, the initial indoor temperature refers to the indoor temperature at the initial moment, for example, it can be expressed as T. 1_save (0) is represented. Since the air conditioner only operates in energy-saving mode, its various parameters in normal mode are predicted when it is operating in energy-saving mode. Therefore, it can be assumed that the initial indoor temperature of the air conditioner in normal mode is equal to the initial indoor temperature in energy-saving mode. Therefore, by detecting the initial indoor temperature of the air conditioner in energy-saving mode, the initial indoor temperature of the air conditioner in normal mode can be obtained.

[0136] In some embodiments, in the process of predicting the third indoor temperature at the current operating moment of the air conditioner in normal mode based on the initial indoor temperature, the formula can be used first. and formula The compressor operating frequency and indoor fan speed at the initial moment (k=0) are predicted. Then, based on the initial indoor temperature, initial outdoor temperature, compressor operating frequency, and indoor fan speed in normal mode, and the initial indoor temperature, initial outdoor temperature, compressor operating frequency, and indoor fan speed in energy-saving mode, the initial indoor heat exchanger temperature in normal mode is predicted. Next, based on the initial indoor temperature, initial indoor heat exchanger temperature, compressor operating frequency, and indoor fan speed in normal mode, the initial cooling capacity in normal mode is predicted. At this time, the initial heat load in energy-saving mode is also calculated, and the initial heat load in normal mode is predicted based on the initial heat load in energy-saving mode. Finally, based on the initial heat load and initial cooling capacity in normal mode, the indoor temperature at the first moment (k=1) in normal mode is predicted. Next, based on the indoor temperature at the first moment (i.e., k=1) of the air conditioner in normal mode, the above operation is repeated to obtain the indoor temperature at each moment of the air conditioner in normal mode, which is also the third indoor temperature at the current operating moment of the air conditioner in normal mode.

[0137] In some embodiments, after predicting the third indoor temperature at the current operating moment of the air conditioner in normal mode based on the initial indoor temperature, the temperature can be determined according to the formula. and formula This is used to predict the operating frequency of the third compressor and the speed of the third indoor fan at the current operating moment of the air conditioner in normal mode. For explanations of these two formulas, please refer to the previous descriptions; they will not be repeated here.

[0138] In some embodiments, in the process of predicting the temperature of the third indoor heat exchanger at the current operating moment of the air conditioner in normal mode based on the third indoor temperature, the third compressor operating frequency, and the third indoor fan speed, the first indoor temperature, the first outdoor temperature, the first compressor operating frequency, the first indoor fan speed, and the first indoor heat exchanger temperature at the current operating moment of the air conditioner in energy-saving mode can be determined first; then, based on the difference between the first indoor temperature and the third indoor temperature, the difference between the first outdoor temperature and the third outdoor temperature, the difference between the first compressor operating frequency and the third compressor operating frequency, the difference between the first indoor fan speed and the third indoor fan speed, and the first indoor heat exchanger temperature, the temperature of the third indoor heat exchanger at the current operating moment of the air conditioner in normal mode can be predicted. In the process of predicting the temperature of the third indoor heat exchanger in normal mode at the current operating moment based on the differences between the first and third indoor temperatures, the first and third outdoor temperatures, the differences between the operating frequencies of the first and third compressors, the differences between the speeds of the first and third indoor fans, and the temperature of the first indoor heat exchanger, the process can first predict the temperature difference between the energy-saving mode and normal mode at the current operating moment based on these differences. Then, based on the temperature of the first indoor heat exchanger and the temperature difference between the third and fourth indoor temperatures, the first and third outdoor temperatures, the differences between the operating frequencies of the first and third compressors, the differences between the speeds of the first and third indoor fans, and the temperature of the first indoor heat exchanger, the process can predict the temperature of the third indoor heat exchanger in normal mode at the current operating moment. For example, assuming the first indoor temperature is T... 1_save (k), the first outdoor temperature is T 4_save (k), the operating frequency of the first compressor is Fr _save (k), the speed of the first indoor fan is W _save (k), the third indoor temperature is The third outdoor temperature is T. 4_normal (k), the operating frequency of the third compressor is The speed of the third indoor fan is Then we can first calculate the differences according to the following formulas (3) to (6):

[0139]

[0140] In formulas (3) to (6), ΔFr is the difference between the operating frequency of the first compressor and the operating frequency of the third compressor, ΔW is the difference between the speed of the first indoor fan and the speed of the third indoor fan, ΔT4 is the difference between the first outdoor temperature and the third outdoor temperature, and ΔT1 is the difference between the first indoor temperature and the third indoor temperature. After calculating these differences, these differences and the temperature of the first indoor heat exchanger at the current operating moment of the air conditioner in energy-saving mode are input as parameters into a pre-trained first machine learning model for predicting the temperature difference between the indoor heat exchanger in energy-saving mode and normal mode. The temperature difference between the indoor heat exchanger in energy-saving mode and normal mode output by this first machine learning model can then be obtained. In some embodiments, the first machine learning model can be represented as:

[0141]

[0142] Among them, T 2_save (k) refers to the temperature of the first indoor heat exchanger, and model1() represents the first machine learning model. This first machine learning model can be trained using historical experimental data, which will not be elaborated here.

[0143] When the temperature difference of the indoor heat exchanger between energy-saving mode and normal mode is predicted by the first machine learning model Then, the temperature T of the first indoor heat exchanger was set. 2_save (k) and the temperature difference of the indoor heat exchanger Subtracting the two values ​​yields the temperature of the third indoor heat exchanger at the current operating moment of the air conditioner in normal mode. For example, this can be achieved using the formula... The formula calculates the temperature of the third indoor heat exchanger at the current operating moment of the air conditioner in normal mode. This represents the temperature of the third indoor heat exchanger at the current operating moment of the air conditioner in normal mode.

[0144] In some embodiments, in the process of predicting the second cooling capacity of the air conditioner at the current operating moment in normal mode based on the temperature of the third indoor heat exchanger, the temperature of the third indoor room, the operating frequency of the third compressor and the speed of the third indoor fan, the temperature of the third indoor heat exchanger, the temperature of the third indoor room, the operating frequency of the third compressor and the speed of the third indoor fan can be used as input parameters and input into the previous formula (1) to predict the second cooling capacity of the air conditioner at the current operating moment in normal mode.

[0145] In some embodiments, such as Figure 9 As shown, the process of predicting the second heat load of the air conditioner at the current operating moment in normal mode based on the first heat load may include, but is not limited to, the following steps S6131 to S6134.

[0146] Step S6131: Determine the first indoor-outdoor temperature difference at the previous operating moment when the air conditioner is in energy-saving mode;

[0147] Step S6132: Determine the third outdoor temperature at the current operating moment when the air conditioner is in normal mode;

[0148] Step S6133: Based on the third outdoor temperature and the third indoor temperature, determine the third indoor-outdoor temperature difference at the current operating moment of the air conditioner in normal mode;

[0149] Step S6134: Based on the first heat load, the first indoor-outdoor temperature difference, and the third indoor-outdoor temperature difference, predict the second heat load of the air conditioner at the current operating moment in normal mode.

[0150] In some embodiments, since the air conditioner only operates in energy-saving mode, its various parameters in normal mode are predicted when it operates in energy-saving mode. The first outdoor temperature when the air conditioner is in energy-saving mode and the second and third outdoor temperatures when it is in normal mode all refer to the outdoor temperature. Under normal circumstances, the outdoor temperature does not change much. Therefore, it can be considered that the first outdoor temperature when the air conditioner is in energy-saving mode and the second and third outdoor temperatures when it is in normal mode are equal.

[0151] In some embodiments, in determining the third indoor-outdoor temperature difference at the current operating time of the air conditioner in normal mode based on the third outdoor temperature and the third indoor temperature, the third indoor temperature can be subtracted from the third outdoor temperature to obtain the third indoor-outdoor temperature difference at the current operating time of the air conditioner in normal mode.

[0152] In some embodiments, when predicting the second heat load of the air conditioner at the current operating moment in normal mode based on the first heat load, the first indoor-outdoor temperature difference, and the third indoor-outdoor temperature difference, it can be achieved by the following formula (7):

[0153]

[0154] In formula (7), This refers to the second heat load of the air conditioner at the current operating moment in normal mode; This refers to the third indoor temperature, T. 4_normal (k) refers to the third outdoor temperature. This refers to the third indoor-outdoor temperature difference; T 1_save (k-1)-T 4_save (k-1) refers to the first indoor-outdoor temperature difference; Q load_save (k-1) refers to the first heat load; K loadThis refers to the load correction coefficient, which can be selected or adjusted according to different environments and operating conditions, and is not specifically limited here. Therefore, after obtaining the first heat load, the first indoor-outdoor temperature difference, and the third indoor-outdoor temperature difference, the first heat load, the first indoor-outdoor temperature difference, and the third indoor-outdoor temperature difference are input into formula (7) as input parameters, and the second heat load of the air conditioner at the current operating time in normal mode can be predicted.

[0155] In some embodiments, in the process of predicting the second indoor temperature of the air conditioner at the next operating moment in normal mode based on the second cooling capacity and the second heat load, the indoor temperature difference of the air conditioner at the current operating moment in normal mode can be predicted first based on the second cooling capacity and the second heat load, and then the second indoor temperature of the air conditioner at the next operating moment in normal mode can be predicted based on the third indoor temperature and the indoor temperature difference. The indoor temperature difference of the air conditioner at the current operating moment in normal mode can be predicted using the following formula (8):

[0156]

[0157] In formula (8), This refers to the indoor temperature difference at the current operating moment of the air conditioner in normal mode; This refers to the second cooling capacity; dt refers to the power saving prediction update cycle. This refers to the second heat load; C refers to the specific heat capacity of the air in the space where the air conditioner is located; ρ refers to the air density in the space where the air conditioner is located; V room This refers to the spatial volume of the space where the air conditioner is located; *1000 indicates unit conversion. Therefore, after obtaining the second cooling capacity and the second heat load, the second cooling capacity and the second heat load are input into formula (8) as input parameters, and the indoor temperature difference at the current operating time of the air conditioner in normal mode can be predicted.

[0158] In some embodiments, after predicting the indoor temperature difference at the current operating moment of the air conditioner in normal mode, the formula can be used to... The second indoor temperature at the next operating moment of the air conditioner in normal mode is predicted. This refers to the second indoor temperature at the next operating moment of the air conditioner in normal mode. This refers to the third indoor temperature. This refers to the indoor temperature difference at the current operating moment of the air conditioner in normal mode.

[0159] In addition, it should be noted that the above methods and formulas can be continuously iterated and updated to predict the indoor temperature, indoor heat exchanger temperature, indoor fan speed and compressor operating frequency of the air conditioner at each operating moment in normal mode in real time. This helps to predict the power saving of the energy-saving mode compared to the normal mode.

[0160] In some embodiments, when predicting the second total power of the air conditioner in normal mode based on the first difference between the operating frequencies of the first and second compressors, the second difference between the speeds of the first and second indoor fans, the third difference between the first and second outdoor temperatures, and the first total power, the total power deviation between the energy-saving mode and the normal mode can be predicted first based on the first difference between the operating frequencies of the first and second compressors, the second difference between the speeds of the first and second indoor fans, the third difference between the first and second outdoor temperatures, and the first total power. Then, the second total power of the air conditioner in normal mode can be obtained based on the first total power and the total power deviation. Specifically, the first difference between the operating frequencies of the first and second compressors, the second difference between the speeds of the first and second indoor fans, the third difference between the first and second outdoor temperatures, and the first total power can be input as parameters into a pre-trained second machine learning model for predicting the total power deviation between the energy-saving mode and the normal mode. This yields the total power deviation between the energy-saving mode and the normal mode output by the second machine learning model. In some embodiments, the second machine learning model can be represented as:

[0161]

[0162] Among them, P _save (k) refers to the first total power, ΔFr is the difference between the operating frequency of the first compressor and the operating frequency of the third compressor, ΔW is the difference between the speed of the first indoor fan and the speed of the third indoor fan, ΔT4 is the difference between the first outdoor temperature and the third outdoor temperature, and model2() represents the second machine learning model. This second machine learning model can be trained using historical experimental data, which will not be elaborated here.

[0163] When the power deviation between energy-saving mode and normal mode is predicted by the second machine learning model Then, the first total power P of the machine was... _save (k) Deviation value from the overall power of the machine Subtracting the two values ​​will give you the second total power of the air conditioner in normal mode. For example, you can use the formula... The second total power of the air conditioner in normal mode is calculated using this formula. This represents the second total power of the air conditioner in normal mode.

[0164] In some embodiments, in determining the first power consumption corresponding to the first overall power and the second power consumption corresponding to the second overall power, a preset power saving prediction update cycle can be obtained first. Then, based on the first overall power and the power saving prediction update cycle, the first power consumption corresponding to the first overall power is determined, and based on the second overall power and the power saving prediction update cycle, the second power consumption corresponding to the second overall power is determined. The first power consumption corresponding to the first overall power and the second power consumption corresponding to the second overall power can be obtained using the following formula (9):

[0165]

[0166] In formula (9), E _ (k) refers to the power consumption corresponding to the total power of the machine, such as the first power consumption corresponding to the first total power, or the second power consumption corresponding to the second total power; P _ (k) refers to the total power, such as the first total power or the second total power; dt refers to the power saving prediction update cycle, and k refers to the number of moments within the power saving prediction update cycle. Therefore, after determining the number of moments within the power saving prediction update cycle and the first total power and the second total power, the first power consumption corresponding to the first total power and the second power consumption corresponding to the second total power can be determined by formula (9).

[0167] In some embodiments, after determining the first power consumption corresponding to the first overall power and the second power consumption corresponding to the second overall power through formula (9), the formula can be used to... The predicted power savings of the energy-saving mode compared to the normal mode are obtained. This refers to the power saving of the energy-saving mode compared to the normal mode. E refers to the second power consumption corresponding to the second total power of the machine. _save (k) refers to the first power consumption corresponding to the first total power of the machine.

[0168] In some embodiments, after the air conditioner predicts the power saving in energy-saving mode compared to normal mode, the air conditioner can report the predicted power saving to the cloud server. At this time, the cloud server can send the received power saving to the air conditioner control application on the user terminal for display. The user can conveniently know the power saving of the air conditioner in energy-saving mode compared to normal mode through the information displayed by the air conditioner control application.

[0169] The power saving prediction method for air conditioners provided by the embodiments of the present invention can determine the first total power, first compressor operating frequency, first indoor fan speed, and first outdoor temperature of the air conditioner when it is in energy-saving mode, and predict the second compressor operating frequency, second indoor fan speed, and second outdoor temperature when the air conditioner is in normal mode. Then, based on the first difference between the first compressor operating frequency and the second compressor operating frequency, the second difference between the first indoor fan speed and the second indoor fan speed, the third difference between the first outdoor temperature and the second outdoor temperature, and the first total power, the second total power of the air conditioner in normal mode is predicted. Then, the first power consumption corresponding to the first total power and the second power consumption corresponding to the second total power are determined. Finally, based on the first power consumption and the second power consumption, the power saving of the energy-saving mode relative to the normal mode can be predicted. Since the second total power of the air conditioner in normal mode is predicted when it is in energy-saving mode, the second total power of the air conditioner in normal mode and the first total power in energy-saving mode can correspond to the same operating environment. Therefore, the deviation between the first power consumption corresponding to the first total power and the second power consumption corresponding to the second total power can be reduced, thereby improving the prediction accuracy of power saving in energy-saving mode compared to normal mode.

[0170] The following describes the process of calculating energy-saving statistics and displaying energy-saving data of the air conditioner provided in this embodiment of the invention, using specific examples.

[0171] Reference Figure 10The process of energy-saving statistics for the air conditioner shown is as follows: When the user controls the air conditioner to operate in energy-saving mode, the air conditioner first obtains the compressor operating frequency and indoor fan speed in energy-saving mode. Then, based on the compressor operating frequency and indoor fan speed, it calculates the cooling capacity at time K-1. Next, it calculates the indoor temperature difference at this time and, based on the cooling capacity and indoor temperature difference, calculates the heat load of the air conditioner at time K-1 in energy-saving mode. At this point, the air conditioner, based on the indoor and outdoor temperature difference and the heat load at time K-1 in energy-saving mode, combined with the predicted indoor and outdoor temperature difference in normal mode, predicts the heat load of the air conditioner at time K in normal mode. In addition, the air conditioner also predicts the indoor heat exchanger temperature (e.g., evaporator temperature) at time K in normal mode based on its compressor operating frequency, indoor fan speed, and outdoor temperature in energy-saving mode, as well as the predicted compressor operating frequency, indoor fan speed, and outdoor temperature in normal mode. Combined with the indoor heat exchanger temperature (e.g., evaporator temperature) at time K in energy-saving mode, the air conditioner predicts the indoor heat exchanger temperature (e.g., evaporator temperature), compressor operating frequency, and indoor fan speed at time K in normal mode. Then, based on the predicted indoor heat exchanger temperature (e.g., evaporator temperature), compressor operating frequency, and indoor fan speed at time K in normal mode, the air conditioner predicts the cooling capacity at time K in normal mode. Next, based on the predicted heat load and cooling capacity at time K in normal mode, the air conditioner predicts the indoor temperature at time K+1 in normal mode. This process is repeated to predict the indoor temperature at each time in normal mode. Furthermore, based on the predicted indoor temperature at each time in normal mode, the corresponding compressor operating frequency, indoor fan speed, and outdoor temperature in normal mode can be predicted. At this point, based on the air conditioner's total power, compressor operating frequency, indoor fan speed, and outdoor temperature in energy-saving mode, combined with the predicted compressor operating frequency, indoor fan speed, and outdoor temperature in normal mode, a pre-trained power prediction model (i.e., the second machine learning model mentioned earlier) is invoked to predict the deviation of the air conditioner's total power between energy-saving and normal modes. Then, based on the predicted total power deviation and the air conditioner's total power in energy-saving mode, the total power of the air conditioner in normal mode can be predicted. Next, based on these two total power values, the power consumption of the air conditioner in energy-saving mode and in normal mode can be determined respectively. Finally, based on the power consumption in energy-saving mode and in normal mode, the power saving of the air conditioner in energy-saving mode compared to normal mode can be predicted.

[0172] Reference Figure 11 As shown, when the air conditioner operates as follows Figure 10During the energy-saving statistics process, the air conditioner controls the energy-saving indicator light on its display panel to display in a running light mode to indicate that the air conditioner is performing energy-saving statistics. Once the air conditioner exits energy-saving mode and the predicted energy savings are obtained, the air conditioner controls the energy-saving indicator light to exit the running light mode and display in the first illuminated mode to indicate the energy savings in energy-saving mode. Simultaneously, the air conditioner also sends the predicted energy savings directly to the air conditioner control application on the user's terminal, or sends the calculated energy savings to the air conditioner control application on the user's terminal via a cloud server. At this time, the air conditioner control application on the user's terminal will display the current energy savings of the air conditioner in energy-saving mode on the application interface.
