[0002] With the increasing global energy tension, people's awareness of environmental protection and energy conservation is getting stronger. For household appliances in daily life, people also pay more and more attention to their environmental protection and energy conservation. As a high-power household appliance, people have higher and higher requirements for the energy consumption of air conditioners.

[0003] In order to actively follow up on energy consumption reduction measures, a scientific load management method can be adopted. By sending an energy consumption reduction instruction to the air conditioner on the user side, the energy consumption of the air conditioner can be reduced by reducing the operating power of the air conditioner. However, the currently available methods lack accuracy in this regard, resulting in the operating power of the air conditioner not being accurately reduced and unable to meet the requirements of energy consumption reduction.

[0041] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0042] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

The specific meaning needs to be understood in combination with the context.

[0045] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design solution described as "exemplary" or "for example" in the embodiments of the present application should not be construed as being more preferred or having more advantages than other embodiments or design solutions. Exactly speaking, using words such as "exemplary" or "for example" aims to present relevant concepts in a specific way.

[0046] Figure 1 This is a schematic diagram of an application scenario provided by the present application according to an exemplary embodiment. As Figure 1 shown, the application scenario includes an air conditioner 101, a cloud server 102, and a power grid system 103.

[0047] The air conditioner 101 is a device for adjusting and controlling parameters such as the temperature, humidity, and flow rate of the indoor air in a building or structure. The air conditioner 101 may be a floor-standing air conditioner, a wall-mounted air conditioner, a central air conditioner, etc. The present application does not impose special restrictions on the specific form of the air conditioner 101.

[0048] The cloud server 102 can be a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud storage, network services, cloud communications, middleware services, domain name services, security services, content delivery networks, big data servers, etc. The specific form of the cloud server 102 is not particularly limited in this application.

[0049] The power grid system 103 is used to transmit electric energy from the power plant to the user side. In terms of energy consumption management, the power grid system 103 can send energy consumption reduction instructions to the devices on the user side (such as the air conditioner 101) through intelligent technologies and load management means to achieve refined control of power consumption, so as to better cope with the balance between power supply and demand.

[0050] Optionally, the energy consumption reduction instruction can include the operating mode, operating time, energy consumption reduction value, energy consumption reduction strategy, etc. of the air conditioner 101 to reduce the overall energy consumption, improve the operating efficiency of the power grid, and meet the user's needs.

[0051] Figure 2 This is a schematic diagram of the composition of an air conditioner provided by an embodiment of this application. As Figure 2 shown, the air conditioner 101 includes an indoor unit 201, an outdoor unit 202, and a controller 203 ( Figure 2 not shown in the figure).

[0052] The indoor unit 201, taking the indoor wall-mounted unit as an example of the indoor unit 201, the indoor wall-mounted unit is usually installed on the indoor wall surface, etc. For another example, the indoor cabinet unit is also a form of the indoor unit.

[0053] The outdoor unit 202 is usually set outdoors and is used for heat exchange in the indoor environment. In addition, in Figure 2 the figure, since the outdoor unit 202 is located outdoors on the opposite side of the indoor unit 201 across the wall surface, the outdoor unit 202 is represented by a dashed line.

[0054] The controller 203 refers to a device that can generate operation control signals according to the instruction operation code and timing signals to direct the air conditioner to execute control instructions. Exemplarily, the controller can be a central processing unit (CPU), a general-purpose processor, a network processor (NP), a digital signal processor (DSP), a micro control unit (MCU), a microprocessor, a microcontroller, a programmable logic device (PLD), or any combination thereof. The controller 203 can also be other devices with processing functions, such as circuits, devices, or software modules, and the embodiments of the present application do not impose any restrictions thereon.

[0055] In addition, the controller 203 can be used to control the operation of each component inside the air conditioner 101, so that the operation of each component of the air conditioner 101 realizes each predetermined function of the air conditioner.

[0056] Figure 3 This is a schematic structural diagram of an air conditioner provided by an embodiment of the present application. As Figure 3 shown, the air conditioner 101 further includes a compressor 301, an outdoor heat exchanger 302, an expansion valve 303, a liquid receiver 304, and an indoor heat exchanger 305.

[0057] Among them, the indoor heat exchanger 305 belongs to a part of the indoor unit 201, and the compressor 301, the outdoor heat exchanger 302, and the liquid receiver 304 belong to a part of the outdoor unit 202.

[0058] In some embodiments, the compressor 301 sucks in the refrigerant from the suction port, compresses it, and discharges the compressed refrigerant inside it from the discharge port to the indoor heat exchanger 305. The compressor 301 can be a variable-capacity inverter compressor that performs inverter-based speed control.

[0059] In some embodiments, the outdoor heat exchanger 302 has a first inlet / outlet for allowing the refrigerant to flow between the outdoor heat exchanger 302 and the suction port of the compressor 301 via the liquid receiver 304, and has a second inlet / outlet for allowing the refrigerant to flow between the expansion valve 303. The outdoor heat exchanger 302 exchanges heat between the heat medium flowing in the heat transfer tubes connected between the first inlet / outlet and the second inlet / outlet and the outdoor air.

[0060] In some embodiments, the expansion valve 303 has the function of expanding and decompressing the refrigerant flowing through the expansion valve 303, and can be used to adjust the supply amount of the refrigerant in the pipeline. If the opening degree of the expansion valve 303 is reduced, the flow path resistance of the refrigerant passing through the expansion valve 303 increases. If the opening degree of the expansion valve 303 is increased, the flow path resistance of the refrigerant passing through the expansion valve 303 decreases. Thus, even if the states of other devices in the circuit do not change, when the opening degree of the expansion valve 303 changes, the refrigerant flow rate flowing into the indoor unit 201 also changes.

[0061] In some embodiments, one end of the accumulator 304 is connected to the compressor 301, and the other end is connected to the outdoor heat exchanger 302. In the accumulator 304, the refrigerant flowing from the outdoor heat exchanger 302 to the compressor 301 is separated into gaseous refrigerant and liquid refrigerant. And, mainly gaseous refrigerant is supplied from the accumulator 304 to the suction port of the compressor 301.

[0062] In some embodiments, the indoor heat exchanger 305 has a third inlet / outlet for allowing liquid refrigerant to flow between it and the expansion valve 303, and has a fourth inlet / outlet for allowing gaseous refrigerant to flow between it and the discharge port of the compressor 301. The indoor heat exchanger 305 exchanges heat between the refrigerant flowing in the heat transfer pipe connected between the third inlet / outlet and the fourth inlet / outlet and the indoor air.

[0063] Figure 4 This is a hardware configuration block diagram of an air conditioner provided by an embodiment of the present application. As Figure 4 shown, the air conditioner 101 may further include a communicator 401 and a memory 402.

[0064] In some embodiments, the communicator 401 is used to establish a communication connection with other network entities, such as establishing a communication connection with the terminal 104 and the air conditioner 101. The communicator 401 may include a radio frequency (RF) module, a cellular module, a wireless fidelity (WIFI) module, a GPS module, etc. Taking the RF module as an example, the RF module can be used for signal reception and transmission. In particular, the received information is sent to the controller 203 for processing; in addition, the signal generated by the controller 203 is sent out. Usually, the RF circuit may include but is not limited to an antenna, at least one amplifier, a transceiver, a coupler, a low noise amplifier (LNA), a duplexer, etc.

[0065] In some embodiments, the memory 402 is used to store application programs and data. The controller 203 executes various functions and data processing of the air conditioner 101 by running the application programs and data stored in the memory 402. The memory 402 mainly includes a program storage area and a data storage area. Among them, the program storage area can store an operating system and application programs required for at least one function (such as a voice prompt function, an information display function, etc.); the data storage area can store data created when using the air conditioner 101. In addition, the memory 402 may include a high-speed random access memory, and may also include a non-volatile memory, such as a disk storage device, a flash memory device, or other volatile solid-state storage devices, etc.

[0066] Those skilled in the art can understand that Figure 4 the hardware structure shown in does not constitute a limitation on the air conditioner. The air conditioner may include more or fewer components than shown in the figure, or combine certain components, or have different component arrangements.

[0067] Figure 5 is a hardware configuration block diagram of a cloud server provided by an embodiment of the present application. As Figure 5 shown, the cloud server 102 includes a processor 501, a memory 502, and a communicator 503.

[0068] The processor 501 may be a central processing unit (CPU), or an application specific integrated circuit (ASIC), or one or more integrated circuits configured to implement the embodiments of the present disclosure. For example: one or more digital signal processors (DSPs), or one or more field programmable gate arrays (FPGAs).

[0069] In addition, for the memory 502, reference may be made to the specific description of the memory 402 above, and for the communicator 203, reference may be made to the specific description of the communicator 401 above. The present application will not elaborate here.

[0070] Those skilled in the art can understand that Figure 5 the structure shown in does not constitute a limitation on the cloud server. The cloud server may include more or fewer components than shown in the figure, or combine certain components, or have different component arrangements.

[0071] Figure 6 is a schematic diagram of the composition of an energy consumption adjustment system provided by an embodiment of the present application. As Figure 6As shown, the energy consumption regulation system 600 includes an air conditioner 601, a cloud server 602, and a collection device 603.

[0072] In addition, for the air conditioner 601, reference can be made to the specific description of the air conditioner 101 in the above Figures 1 - 4 shown embodiment. For the cloud server 602, reference can be made to the specific description of the cloud server 102 in the above Figure 1 and Figure 5 . The present application will not elaborate here.

[0073] In some embodiments, the collection device 603 can be a collection device belonging to the energy consumption regulation system 600, or a collection device belonging to the cloud server 602, or a collection device belonging to the power grid system 103. The collection device 603 is used to collect the electricity consumption data of the air conditioner 601.

[0074] Next, with reference to the accompanying drawings of the specification, the embodiments provided by the present application will be specifically introduced.

[0075] As Figure 7 shown, an embodiment of the present application provides a control method for a cloud server. The method includes the following steps:

[0076] S101. After the cloud server sends a first energy consumption reduction instruction to the air conditioner, it obtains the actual operating power and the expected operating power of the air conditioner after executing the first energy consumption reduction strategy indicated by the first energy consumption reduction instruction.

[0077] Among them, the first energy consumption reduction strategy is used to indicate that when the operating current of the air conditioner is greater than or equal to the first current threshold, the operating frequency of the compressor is reduced. The expected operating power is the operating power that the air conditioner is expected to reach after executing the first energy consumption reduction strategy indicated by the energy consumption reduction instruction.

[0078] Exemplarily, as Figure 8 shown, the first current threshold is I2. If the operating current of the air conditioner is less than or equal to the first current threshold I2, that is, the operating current of the air conditioner is on the right side of the first current threshold I2 as shown in Figure 8 shown, the air conditioner can control the operating frequency of the compressor in the normal operating control manner. If the operating current of the air conditioner is greater than the first current threshold I2, that is, the operating current of the air conditioner is on the left side of the first current threshold I2 as shown in Figure 8 shown, for example, the operating current of the air conditioner is I2 + a, and the operating current I2 + a is greater than the first current threshold I2. In this case, the air conditioner needs to reduce the operating frequency of the compressor.

[0079] It should be noted that the energy consumption refers to the total amount of energy consumed by an air conditioner within a specific time period. The operating power refers to the energy consumed by the air conditioner per unit time. In an air conditioner, the operating power usually represents the electrical energy consumption during the operation of the air conditioner. Therefore, reducing the energy consumption of the air conditioner can be achieved by reducing the operating power of the air conditioner. Reducing the operating power of the air conditioner means reducing the energy consumed by the air conditioner per unit time, thereby reducing the total energy consumed during the operation of the air conditioner.

[0080] Exemplarily, the air conditioner can execute the first energy consumption reduction strategy by adjusting the inverter or frequency converter in the air conditioner control system. The inverter or frequency converter is a key component for controlling the operating frequency of the compressor in the air conditioner. When the operating current of the air conditioner is greater than or equal to the first current threshold, the inverter or frequency converter will automatically reduce the operating frequency of the compressor. Reducing the operating frequency will reduce the rotational speed and power consumption of the compressor, thereby reducing the energy consumption of the air conditioner. Additionally, reducing the operating frequency can also reduce the noise and vibration of the compressor, improving comfort.

[0081] In some embodiments, the cloud server can generate an energy consumption reduction instruction based on the power consumption data of the air conditioner and the energy consumption reduction requirement issued by the power grid system, so as to instruct the air conditioner to execute the energy consumption reduction strategy indicated by the energy consumption instruction, thereby reducing the energy consumption of the air conditioner. In addition, regarding the generation of the energy consumption reduction instruction, reference can specifically be made to the description in the embodiments shown below. Figure 12 This application will not elaborate here.

[0082] In some embodiments, the cloud server can establish a communication connection with the air conditioner, send a first energy consumption reduction instruction to the air conditioner through the remote control interface, and obtain the actual operating power and the expected operating power of the air conditioner after executing the first energy consumption reduction strategy indicated by the first energy consumption reduction instruction.

[0083] Exemplarily, the cloud server can be connected to sensors in the air conditioner, such as current sensors, voltage sensors, etc., to monitor the operating parameters of the air conditioner in real time. Furthermore, after the air conditioner executes the first energy consumption reduction strategy indicated by the first energy consumption reduction instruction, the cloud server can obtain the actual operating power of the air conditioner by reading the sensor data.

[0084] S102. The cloud server adjusts the first energy consumption reduction strategy indicated by the first energy consumption reduction instruction according to the difference between the actual operating power and the expected operating power, and obtains the target energy consumption reduction strategy indicated by the second energy consumption reduction instruction.

[0085] In some embodiments, the cloud server can directly determine the target energy consumption reduction strategy indicated by the second energy consumption reduction instruction based on the magnitude relationship between the difference and the preset difference, so as to adjust the first energy consumption reduction strategy indicated by the first energy consumption reduction instruction. This method can simplify the decision-making process of the energy consumption adjustment strategy, only need to judge the magnitude relationship between the difference and the preset difference, without complex calculations or analyses, and improve the decision-making efficiency.

[0086] Alternatively, the cloud server can also obtain the ratio between the difference and the expected operating power, and then determine the target energy consumption reduction strategy indicated by the second energy consumption reduction instruction based on the magnitude relationship between the ratio and the preset threshold, so as to adjust the first energy consumption reduction strategy indicated by the first energy consumption reduction instruction.

[0087] It can be understood that by using the ratio of the difference to the expected operating power for relative evaluation, the cloud server not only focuses on the actual difference but also considers the magnitude of the expected operating power. This method can better judge the gap between the actual operating power and the expected operating power, avoiding the limitation of making judgments only relying on the difference. In addition, it can also largely avoid misjudgments, especially when the expected operating power changes greatly. If judged only based on the absolute magnitude of the difference, it may lead to misjudgments and cannot accurately reflect the gap between the actual operating power and the expected operating power. In summary, by using the magnitude relationship between the ratio of the difference to the expected operating power and the preset threshold for judgment, the cloud server can more accurately judge the gap between the actual operating power and the expected operating power, thus better guiding the determination of the target energy consumption reduction strategy indicated by the second energy consumption reduction instruction.

[0088] In some embodiments, the cloud server can adjust the magnitude of the first current threshold in the first energy consumption reduction strategy according to the magnitude relationship between the ratio and the preset threshold, to obtain the target energy consumption reduction strategy indicated by the second energy consumption reduction instruction, thereby more accurately reducing the energy consumption of the air conditioner.

[0089] It can be understood that adjusting the magnitude of the first current threshold actually limits the maximum current value that the air conditioner can accommodate. When the voltage remains unchanged, that is, it adjusts the upper limit of the operating power of the air conditioner. By adjusting the current threshold, the operating power of the air conditioner is also dynamically adjusted. In this way, this dynamic adjustment method can make the actual operating power of the air conditioner close to or equal to the expected operating power, thereby more accurately reducing the energy consumption of the air conditioner.

[0090] In some embodiments, the cloud server sets a control accuracy, that is, if the ratio is equal to or close to the control accuracy, it is determined that the actual operating power is equal to or close to the expected operating power.

[0091] Exemplarily, regarding how to adjust the first current threshold, reference can be made to the specific description in the embodiments shown below. This application will not elaborate herein. Figure 9 Shown in the embodiments described below, this application will not elaborate herein.

[0092] S103. The cloud server sends a second energy consumption reduction instruction to the air conditioner so that the air conditioner executes the target energy consumption reduction strategy indicated by the second energy consumption reduction instruction.

[0093] In some embodiments, the cloud server sends a second energy consumption reduction instruction to the air conditioner through a communicator, and then the air conditioner executes the target energy consumption reduction strategy indicated by the second energy consumption reduction instruction to reduce its own energy consumption, so that the actual operating power after energy consumption reduction is close to or equal to the expected operating power.

[0094] In some embodiments, as Figure 9 shown, step S102 can be implemented as the following steps:

[0095] S201. When the actual operating power is less than the expected operating power and the ratio of the difference to the expected operating power reaches a preset threshold or more, the cloud server determines the second energy consumption reduction strategy as the target energy consumption reduction strategy indicated by the second energy consumption reduction instruction.

[0096] Among them, the second energy consumption reduction strategy is used to indicate that when the operating current of the air conditioner is greater than or equal to the second current threshold, the operating frequency of the compressor is reduced. The second current threshold is greater than the first current threshold.

[0097] Exemplarily, as Figure 10 shown, the second current threshold is I2 + b. If the operating current of the air conditioner is less than or equal to the second current threshold I2 + b, that is, the operating current of the air conditioner is on the right side of the second current threshold I2 + b as shown below, the air conditioner can control the operating frequency of the compressor in the normal operating control manner. If the operating current of the air conditioner is greater than the second current threshold I2 + b, that is, the operating current of the air conditioner is on the left side of the second current threshold I2 + b as shown below, for example, the operating current of the air conditioner is I2 + a + b, and the operating current I2 + a + b is greater than the second current threshold I2 + b. In this case, the air conditioner needs to reduce the operating frequency of the compressor. Figure 10 Shown below, if the operating current of the air conditioner is less than or equal to the second current threshold I2 + b, that is, the operating current of the air conditioner is on the right side of the second current threshold I2 + b as shown below, the air conditioner can control the operating frequency of the compressor in the normal operating control manner. If the operating current of the air conditioner is greater than the second current threshold I2 + b, that is, the operating current of the air conditioner is on the left side of the second current threshold I2 + b as shown below, for example, the operating current of the air conditioner is I2 + a + b, and the operating current I2 + a + b is greater than the second current threshold I2 + b. In this case, the air conditioner needs to reduce the operating frequency of the compressor. Figure 10 Shown below, for example, the operating current of the air conditioner is I2 + a + b, and the operating current I2 + a + b is greater than the second current threshold I2 + b. In this case, the air conditioner needs to reduce the operating frequency of the compressor.

[0098] In addition, regarding the air conditioner's execution of the second energy consumption reduction strategy, reference can be made to the specific description of the air conditioner's execution of the first energy consumption reduction strategy in step S101 above. This application will not elaborate herein.

[0099] It can be understood that if the actual operating power is less than the expected operating power, and the ratio of the difference to the expected operating power reaches or exceeds a preset threshold, it indicates that after the air conditioner executes the first energy consumption reduction strategy indicated by the first energy consumption reduction instruction, the degree of reduction in the operating power is relatively high, and the actual operating power after reduction is much lower than the expected operating power. In this case, the first energy consumption reduction instruction can be adjusted by increasing the current threshold to obtain the target energy consumption reduction strategy indicated by the second energy consumption reduction instruction, thereby avoiding excessive reduction in the operating power of the air conditioner.

[0100] When increasing the current threshold, in fact, the maximum current value that the air conditioner can accommodate is increased, that is, the upper limit of the operating current is increased. When the voltage remains unchanged, the increase in the current threshold enables the air conditioner to handle a higher current load and achieve a higher operating power. In this way, the actual operating power of the air conditioner can be closer to the expected operating power, thereby more accurately reducing the energy consumption of the air conditioner.

[0101] Optionally, the situation where the ratio of the difference to the expected operating power reaches or exceeds the preset threshold includes: the ratio of the difference to the expected operating power is greater than the preset threshold, or the ratio of the difference to the expected operating power is greater than or equal to the preset threshold.

[0102] S202. When the actual operating power is less than the expected operating power and the ratio of the difference to the expected operating power reaches or is less than the preset threshold, the cloud server determines the first energy consumption reduction strategy as the target control strategy indicated by the second energy consumption reduction instruction.

[0103] It can be understood that if the actual operating power is less than the expected operating power and the ratio of the difference to the expected operating power reaches or is less than the preset threshold, it indicates that after the air conditioner executes the first energy consumption reduction strategy indicated by the first energy consumption reduction instruction, the degree of reduction in the operating power is appropriate, and the actual operating frequency after reduction is close to the expected operating power. In this case, the first energy consumption reduction strategy can be kept unchanged, that is, there is no need to adjust the current threshold.

[0104] Optionally, the situation where the ratio of the difference to the expected operating power reaches or is less than the preset threshold includes: the ratio of the difference to the expected operating power is less than the preset threshold, or the ratio of the difference to the expected operating power is less than or equal to the preset threshold.

[0105] S203. When the actual operating power is greater than the expected operating power and the ratio of the difference to the expected operating power reaches or exceeds the preset threshold, the cloud server determines the third energy consumption reduction strategy as the target control strategy indicated by the second energy consumption reduction instruction.

[0106] Among them, the third energy consumption reduction strategy is used to indicate that when the operating current of the air conditioner is greater than or equal to the third preset threshold, the operating frequency of the compressor is reduced. The third preset threshold is less than the first preset threshold.

[0107] Exemplarily, as Figure 11 shown, the third current threshold is I2-b. If the operating current of the air conditioner is less than or equal to the third current threshold I2-b, that is, the operating current of the air conditioner is on the right side of the third current threshold I2-b as Figure 11 shown, the air conditioner can control the operating frequency of the compressor in the normal operating control manner. If the operating current of the air conditioner is greater than the third current threshold I2-b, that is, the operating current of the air conditioner is on the left side of the third current threshold I2-b as Figure 11 shown, for example, the operating current of the air conditioner is I2+a-b, and the operating current I2+a+b is greater than the third current threshold I2-b. In this case, the air conditioner needs to reduce the operating frequency of the compressor.

[0108] In addition, regarding the air conditioner's execution of the third energy consumption reduction strategy, reference can be made to the specific description of the air conditioner's execution of the first energy consumption reduction strategy in the above step S101, and this application will not elaborate here.

[0109] It can be understood that if the actual operating power is greater than the expected operating power, and the ratio of the difference to the expected operating power reaches above the preset threshold, it means that after the air conditioner executes the first energy consumption reduction strategy indicated by the first energy consumption reduction instruction, the degree of reduction in the operating power is low, and the actual operating power after reduction is much higher than the expected operating power. In this case, the first energy consumption reduction instruction can be adjusted by reducing the current threshold to obtain the target energy consumption reduction strategy indicated by the second energy consumption reduction instruction, so as to avoid too little reduction in the operating power of the air conditioner.

[0110] When reducing the current threshold, in fact, the maximum current value that the air conditioner can accommodate is reduced, that is, the upper limit of the operating current is reduced. When the voltage remains unchanged, the reduction of the current threshold enables the air conditioner to handle only a lower current load and achieve a lower operating power. In this way, the actual operating power of the air conditioner can be closer to the expected operating power, thereby more accurately reducing the energy consumption of the air conditioner.

[0111] S204. When the actual operating power is greater than the expected operating power and the ratio of the difference to the expected operating power reaches below the preset threshold, the cloud server determines the first energy consumption reduction strategy as the target control strategy indicated by the second energy consumption reduction instruction.

[0112] It can be understood that if the actual operating power is greater than the expected operating power, and the ratio of the difference to the expected operating power reaches below a preset threshold, it indicates that after the air conditioner executes the first energy consumption reduction strategy indicated by the first energy consumption reduction instruction, the degree of reduction in the operating power is appropriate, and the actual operating power after reduction is close to the expected operating power. In this case, the first energy consumption reduction strategy can be maintained unchanged, that is, there is no need to adjust the current threshold.

[0113] In some embodiments, when the actual operating power is equal to the expected operating power, the first energy consumption reduction strategy is determined as the target control strategy indicated by the second energy consumption reduction instruction.

[0114] It can be understood that if the actual operating power is equal to the expected operating power, it indicates that the operating power of the air conditioner has been accurately reduced. In this case, the first energy consumption reduction strategy can be maintained unchanged, that is, there is no need to adjust the current threshold.

[0115] In some embodiments, in order to determine the first energy consumption reduction strategy indicated by the first energy consumption reduction instruction, as Figure 12 shown, a control method for a cloud server provided in an embodiment of the present application may further include the following steps.

[0116] S301. The cloud server obtains the power consumption data of the air conditioner in the historical time period and the energy consumption reduction requirement sent by the power grid system.

[0117] In some embodiments, the power consumption data may include data such as energy consumption, power consumption, and operating current.

[0118] Optionally, the historical time period may be the last 1 day, the last 2 days, or the last 3 days.

[0119] In some embodiments, the cloud server may periodically obtain the power consumption data of the air conditioner in the historical time period through the acquisition device according to a preset period. Optionally, the preset period is A minutes.

[0120] Optionally, the acquisition device may be an acquisition device affiliated to the cloud server, an acquisition device affiliated to the power grid system, or an acquisition device affiliated to the energy consumption adjustment system. The present application does not make specific limitations on this.

[0121] In one example, when the acquisition device is an acquisition device affiliated to the cloud server, the cloud server can directly obtain the power consumption data of the air conditioner through the acquisition device.

[0122] In another example, when the acquisition device is an acquisition device affiliated to the power grid system, after the acquisition device acquires the power consumption data of the air conditioner, the power grid system sends the power consumption data to the cloud server through the communicator.

[0123] In another example, when the acquisition device belongs to the energy consumption adjustment system, after the acquisition device collects the power consumption data of the air conditioner, the energy consumption adjustment system sends the power consumption data to the cloud server and the power grid system respectively through the communicator.

[0124] In some embodiments, after obtaining the power consumption data of the air conditioner, the cloud server can also obtain a data curve corresponding to the power consumption data. For example, the data curve corresponding to the operating current of the air conditioner is as Figure 13 shown.

[0125] In some embodiments, the power grid system can determine the energy consumption reduction requirement according to the power consumption data of the air conditioner and the energy consumption reduction target.

[0126] Optionally, the energy consumption reduction requirement is usually expressed in the form of a percentage. Optionally, the energy consumption reduction target can be determined based on the load characteristics of the power grid system itself.

[0127] Exemplarily, in the high-temperature weather in summer, the usage of devices such as air conditioners will increase, resulting in an increase in the load of the power grid system. At this time, the energy consumption reduction target is set as: during the period from 2 pm to 6 pm, reduce the current energy consumption of the air conditioner by 5%. If the current energy consumption of the air conditioner is 1000 kWh, based on the above energy consumption reduction target, the energy consumption reduction requirement is to reduce the current energy consumption of the air conditioner by kWh during the period from 2 pm to 6 pm.

[0128] S302. The cloud server processes the power consumption data to obtain the processed power consumption data.

[0129] In some embodiments, the amount of data processed by the cloud server can be determined according to the amount of data used by the power grid system to set the energy consumption reduction requirement.

[0130] Exemplarily, if the power grid system needs to set the energy consumption reduction requirement according to the power consumption data of the air conditioner in the past 3 days, then the cloud server also needs to process the power consumption data of the air conditioner in the past 3 days.

[0131] It can be understood that processing the power consumption data can improve the stability and reliability of the power consumption data, so that the first energy consumption reduction strategy indicated by the first energy consumption reduction instruction can be determined more accurately, thereby improving the accuracy of reducing the energy consumption of the air conditioner.

[0132] In some embodiments, the cloud server's processing of the power consumption data includes interval division processing, data smoothing processing, etc. of the power consumption data.

[0133] Exemplarily, the cloud server's processing of the power consumption data includes the following steps a1-a3.

[0134] Step a1: The cloud server divides the electricity consumption data within the historical time period into electricity consumption data for multiple sub - time periods.

[0135] In some embodiments, the cloud server may divide the electricity consumption data within the historical time period into electricity consumption data for multiple sub - time periods according to a preset rule.

[0136] Exemplarily, the preset rule may be to divide the historical time period into five sub - time periods according to the change of electricity consumption data over time, namely the peak period, the high - peak period, the flat - period, the low - valley period, and the deep - valley period.

[0137] It can be understood that by dividing the historical time period into different sub - time periods, the problem of inaccurate value taking caused by spanning multiple time periods when calculating the average value can be avoided. Because the electricity consumption data may vary significantly within different sub - time periods, if the historical time period is not divided, averaging the electricity consumption data for the entire historical time period may lead to inaccurate calculation results. By clearly dividing the sub - time periods and obtaining the electricity consumption data within each sub - time period, accurate sub - time period average values can be calculated to better reflect the electricity consumption level within each sub - time period.

[0138] Among them, the peak period usually appears during the day, especially during high - temperature weather or when the electricity demand in office places is relatively large. During the peak period, due to the high demand for using air conditioners by users, the electricity consumption data of air conditioners usually remains at a relatively high value. For example, as Figure 14 shown, the operating current of the air conditioner usually remains between C5% of the rated current of the air conditioner and C6% of the rated current. Among them, C5 is less than C6.

[0139] The high - peak period also usually appears during the day and is a time period with relatively large electricity demand. This time period generally lasts for a relatively long time. Users usually use air conditioners to maintain a comfortable indoor temperature during the high - peak period. During the high - peak period, the electricity consumption data of air conditioners usually remains at a relatively high value. For example, as Figure 14 shown, the operating current of the air conditioner usually remains between C4% of the rated current of the air conditioner and C5% of the rated current. Among them, C4 is less than C5.

[0140] The flat - period is a time period with relatively stable electricity demand. The electricity load of the air conditioner is relatively stable during this time period. It is usually a non - peak or non - peak period at night, and the overall electricity load is relatively low. During the flat - period, the electricity consumption data of the air conditioner usually remains at a relatively medium value. For example, as Figure 14 shown, the operating current of the air conditioner usually remains between C3% of the rated current of the air conditioner and C4% of the rated current. Among them, C3 is less than C4.

[0141] The low-demand period is a time period with relatively low electricity demand, usually during the overnight hours at night, and the electricity load of the air conditioner is relatively low. During the low-demand period, the electricity consumption data of the air conditioner usually remains at a relatively low value. For example, as Figure 14 shown, the operating current of the air conditioner usually remains between C2% and C3% of the rated current of the air conditioner. Among them, C2 is less than C3.

[0142] The deep-valley period is the time period with the lowest electricity demand, usually occurring in the late night and early morning hours. During the deep-valley period, few people use the air conditioner, and the corresponding electricity load is extremely low. The electricity consumption data of the air conditioner usually remains at a low value. For example, as Figure 14 shown, the operating current of the air conditioner usually remains between C1% and C2% of the rated current of the air conditioner. Among them, C1 is less than C2.

[0143] In some embodiments, the rated current of the air conditioner is related to the capacity of the outdoor unit of the air conditioner. Air conditioners with outdoor units of different capacities have different rated currents.

[0144] Step a2: The cloud server calculates the average value of the electricity consumption data within a preset time period every preset time period in each sub-time period.

[0145] Among them, the duration of the preset time period is less than the duration of each sub-time period.

[0146] It can be understood that through averaging processing, the instability of electricity consumption data caused by factors such as instantaneous fluctuations and noise can be avoided as much as possible. This can improve the reliability and stability of electricity consumption data, ensure that the electricity consumption data at a certain moment can more accurately represent the electricity consumption data at that moment in the future, and provide a more accurate and stable reference for data analysis and decision-making.

[0147] Exemplarily, the curve of electricity consumption data before averaging is as Figure 15 shown, and the curve of electricity consumption data after averaging is as Figure 16 shown.

[0148] Optionally, the duration of the preset time period is less than 60 minutes and greater than the preset period in step S301 above. For example, if the preset period in step S301 above is 30 minutes, then the duration of the preset time period is a value in (30, 60).

[0149] Exemplarily, taking a sub - time period as the time period between 7 am and 9 am and the preset time period as 30 minutes. In this sub - time period, the cloud server starts calculating the average value of the electricity consumption data at the start time of this sub - time period (i.e., 7 am) for each 30 - minute time interval. The first calculation will be carried out at 7:30 am, calculating the average value of the electricity consumption data from 7 am to 7:30 am. Then, calculate the average value of the electricity consumption data from 7:30 am to 8 am, and then calculate the average value from 8 am to 8:30 am, and so on.

[0150] In some embodiments, there is a situation where the electricity consumption data within the preset time period collected every preset time period spans sub - time periods. In this case, only the electricity consumption data located within the current sub - time period needs to be collected.

[0151] Exemplarily, taking sub - time period 1 as the time period between 7 am and 9 am, sub - time period 2 as the time period between 9 am and 10 am, and the preset time period as 50 minutes. In sub - time period 1, the cloud server calculates the average value of the electricity consumption data from 7 am to 7:50 am. Then, calculate the average value of the electricity consumption data from 7:50 am to 8:40 am, and then calculate the average value of the electricity consumption data from 8:40 am to 9:20 am. However, the electricity consumption data from 8:40 am to 9:20 am includes both the electricity consumption data of sub - time period 1 and sub - time period 2. In this case, in sub - time period 1, only calculate the electricity consumption data from 8:40 am to 9 am.

[0152] S303. The cloud server determines the first energy consumption reduction strategy indicated by the first energy consumption reduction instruction according to the energy consumption reduction requirement and the processed electricity consumption data.

[0153] In some embodiments, the cloud server can calculate the electricity consumption data that meets the energy consumption reduction requirement according to the energy consumption reduction requirement and the processed electricity consumption data. Further, the cloud server can determine the electricity consumption data that meets the energy consumption reduction requirement as the current threshold in the first energy consumption reduction strategy indicated by the first energy consumption reduction instruction.

[0154] Exemplarily, taking the operating current of the electrical power consumption as an example, the operating current after data processing is [1.2, 1.4, 1.6, 1.8, 2.0], and the energy consumption reduction requirement is to reduce the operating current by 10%. In this case, the operating current at each moment is reduced by 10%, and the operating current that meets the energy consumption reduction requirement is [1.08, 1.26, 1.44, 1.62, 1.80]. Then the operating current [1.08, 1.26, 1.44, 1.62, 1.80] is the current threshold at each corresponding moment in the first energy consumption reduction strategy indicated by the first energy consumption reduction instruction, that is, if the actual operating current of the air conditioner at each moment is greater than the operating current that meets the energy consumption reduction requirement at that moment, the operating frequency of the compressor is reduced.

[0155] In some embodiments, the cloud server may also determine the ratio of the electrical power consumption data that meets the energy consumption reduction requirement to the rated electrical power consumption data of the air conditioner as the current threshold in the first energy consumption reduction strategy indicated by the first energy consumption reduction instruction.

[0156] Exemplarily, taking the operating current that meets the energy consumption reduction requirement as [1.08, 1.26, 1.44, 1.62, 1.80] and the rated current as 2.0 as an example, the ratio of the electrical power consumption data that meets the energy consumption reduction requirement to the rated electrical power consumption data of the air conditioner = [0.54, 0.63, 0.72, 0.81, 0.9]. Then the ratio [0.54, 0.63, 0.72, 0.81, 0.9] is the current threshold at each corresponding moment in the first energy consumption reduction strategy indicated by the first energy consumption reduction instruction, that is, if the ratio of the actual operating current of the air conditioner at each moment to the rated current is greater than the ratio at that corresponding moment, the operating frequency of the compressor is reduced.

[0157] In some embodiments, the ratio of the electrical power consumption data of the air conditioner after executing the first energy consumption reduction operation indicated by the first energy consumption reduction instruction to the rated electrical power consumption data of the air conditioner cannot be too low, for example, it cannot be lower than C1%, to ensure comfort during off-peak hours.

[0158] Exemplarily, as Figure 17 shown, a solid line is used to represent the electrical power consumption data of the air conditioner before executing the first energy consumption reduction instruction, and a dashed line is used to represent the expected operating data of the air conditioner after executing the first energy consumption reduction instruction.

[0159] It should be noted that Figure 7 、 Figure 9 and Figure 12 the control methods of the cloud server shown are all executed by the processor of the cloud server.

[0160] As Figure 18As shown in the figure, an embodiment of the present application provides a control method for a cloud server, which is applied to an air conditioner. The method includes the following steps:

[0161] S401. After the air conditioner receives the first energy consumption reduction instruction sent by the cloud server, it sends the actual operating power and the expected operating power after executing the first energy consumption reduction strategy indicated by the first energy consumption reduction instruction to the cloud server.

[0162] In addition, for the specific description, reference may be made to the above step S101, and the present application will not elaborate here.

[0163] S402. The air conditioner responds to the second energy consumption reduction instruction sent by the cloud server and executes the target energy consumption reduction strategy indicated by the second energy consumption reduction instruction.

[0164] In addition, for the specific description, reference may be made to the above step S103, and the present application will not elaborate here.

[0165] It should be noted that both step S401 and step S402 are executed by the controller of the air conditioner.

[0166] Next, as shown in Figure 19 the following embodiments, the complete process of the control method for the cloud server will be introduced exemplarily.

[0167] Step d1. The acquisition device acquires the power consumption data of the air conditioner.

[0168] Step d2. The acquisition device sends the power consumption data to the power grid system and the cloud server.

[0171] Step d5. The cloud server processes the power consumption data set and determines the first energy consumption reduction strategy indicated by the first energy consumption reduction instruction based on the energy consumption reduction demand and the processed power consumption data.

[0172] Step d6. The cloud server sends the first energy consumption reduction instruction to the air conditioner.

[0173] Step d7. The air conditioner executes the first energy consumption reduction strategy indicated by the first energy consumption reduction instruction.

[0174] Step d8. The air conditioner sends the actual operating power and the expected operating power after executing the first energy consumption reduction strategy to the cloud server.

[0175] Step d9: The cloud server adjusts the first energy consumption reduction strategy indicated by the first energy consumption reduction instruction according to the difference between the actual operating power and the expected operating power, and obtains the target energy consumption reduction strategy indicated by the second energy consumption reduction instruction.
