[0041] Some embodiments of this application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this application and are not intended to limit the scope of protection of this application.

A module can include hardware circuitry, various suitable sensors, communication ports, and memory, and may also include software components, such as program code, or a combination of software and hardware. The term "A and / or B" means all possible combinations of A and B, such as only A, only B, or A and B. The terms "at least one A or B" or "at least one of A and B" have a similar meaning to "A and / or B" and can include only A, only B, or A and B. The singular forms of the terms "a" and "this" can also include plural forms.

[0043] See appendix Figure 1 , Figure 1 This is a schematic flowchart illustrating the main steps of an air conditioner control method according to an embodiment of this application. Figure 1 As shown, in this embodiment of the application, the air conditioner is communicatively connected to the cloud server. The control method of the air conditioner in this embodiment mainly includes the following steps S101 to S102.

[0044] Step S101: In response to receiving the demand response command issued by the cloud server, obtain the total current value of the air conditioner.

[0045] In this embodiment, if the air conditioner receives a demand response command from the cloud server, it can obtain the total current value of the air conditioner.

[0046] In one implementation, the air conditioner can be a multi-split air conditioner, a heating, ventilation and air conditioning system, etc.

[0047] In one implementation, the cloud server could be a U.S. power company server.

[0048] Step S102: Control the power consumption of the air conditioner according to the total current value and the demand response command.

[0049] In this embodiment, the power consumption control of the air conditioner can be achieved by combining the total current value and the demand response command.

[0050] In one embodiment of this application, the demand response command may include a first demand response command (DR1), a second demand response command (DR2), and a third demand response command (DR3). Each demand response command is associated with a threshold current to determine how to control the power consumption of the air conditioner. The threshold current corresponding to the first demand response command is a first threshold current, the threshold current corresponding to the second demand response command is a second threshold current, and the threshold current corresponding to the third demand response command is a third threshold current; the first threshold current is greater than the third threshold current, which is greater than the second threshold current.

[0051] In one implementation, a programmed current can be set, and a threshold current can be set as a percentage of the programmed current. For example, the first threshold current is 70% of the programmed current, the second threshold current is 40% of the programmed current, and the third threshold current can be 45% of the programmed current.

[0052] The following describes the power consumption control process for the first demand response instruction (DR1), the second demand response instruction (DR2), and the third demand response instruction (DR3).

[0053] 1. When the demand response instruction is the first demand response instruction (DR1), such as Figure 2 As shown, step S102 may further include steps S1021 to S1024:

[0054] Step S1021: Compare the total current value with the first threshold current.

[0055] Step S1022: If the total current value is less than the first threshold current, then control the air conditioner to operate according to the current state.

[0056] Step S1023: If the total current value is greater than or equal to the first threshold current and less than or equal to the fourth threshold current, then control the air conditioner compressor to reduce the frequency according to the first frequency reduction speed.

[0057] Step S1024: If the total current value is greater than the fourth threshold current, control the air conditioner compressor to reduce its frequency according to the second frequency reduction rate. The first frequency reduction rate is less than the second frequency reduction rate.

[0058] In one implementation, the fourth threshold current can be 75% of the programmed current.

[0059] In one implementation, the first down-frequency rate is 1Hz / 10s, and the second down-frequency rate is 1Hz / s.

[0060] In a specific example, when the air conditioner receives the first demand response command (DR1), it can compare the total current value of the air conditioner with 70% of the program-set current. If the total current value is less than 70% of the program-set current, the air conditioner can be controlled to operate according to the current state. If the total current value is greater than or equal to 70% of the program-set current and less than or equal to 75% of the program-set current, the air conditioner's compressor can be controlled to reduce its frequency at a rate of 1Hz / 10s. If the total current value is greater than 75% of the program-set current, the air conditioner's compressor can be controlled to reduce its frequency at a rate of 1Hz / s.

[0061] 2. When the demand response instruction is the second demand response instruction (DR2), such as Figure 3 As shown, step S102 may further include steps S1025 to S1028:

[0062] Step S1025: Compare the total current value with the second threshold current.

[0063] Step S1026: If the total current value is less than the second threshold current, control the air conditioner to operate according to the current state.

[0064] Step S1027: If the total current value is greater than or equal to the second threshold current and less than or equal to the fifth threshold current, then control the air conditioner compressor to reduce the frequency according to the first frequency reduction speed.

[0065] Step S1028: If the total current value is greater than the fifth threshold current, control the air conditioner compressor to reduce the frequency according to the second frequency reduction speed.

[0066] In one implementation, the fifth threshold current can be 45% of the programmed current.

[0067] In a specific example, when the air conditioner receives a second demand response command (DR2), it can compare the total current value with a second threshold current. If the total current value is less than 40% of the programmed current, the air conditioner can be controlled to exit demand response mode. If the total current value is greater than or equal to 40% of the programmed current and less than or equal to 45% of the programmed current, the air conditioner's compressor can be controlled to reduce its frequency at a rate of 1 Hz / 10 s. If the total current value is greater than 45% of the programmed current, the air conditioner's compressor can be controlled to reduce its frequency at a rate of 1 Hz / s.

[0068] 3. When the demand response instruction is the third demand response instruction (DR3), such as Figure 4 As shown, step S102 may further include steps S1029 to S1031:

[0069] Step S1029: Compare the total current value with the third threshold current.

[0070] Step S1030: If the total current value is greater than the third threshold current, control the air conditioner compressor to reduce the frequency according to the second frequency reduction speed.

[0071] Step S1031: If the total current value is less than or equal to the third threshold current, control the air conditioner compressor to reduce the frequency according to the first frequency reduction speed, and control the air conditioner to stop after reducing the frequency to the minimum frequency of the air conditioner.

[0072] In a specific example, when the air conditioner receives a third demand response command (DR3), it can compare the total current value with 45% of the program-set current. If the total current value is greater than 45% of the program-set current, the air conditioner can be controlled to reduce its frequency at a rate of 1 Hz / s. If the total current value is less than or equal to 45% of the program-set current, the air conditioner can be controlled to reduce its frequency at a rate of 1 Hz / 10s. After reaching the minimum operating frequency of the air conditioner, the air conditioner can be shut down.

[0073] In one embodiment of this application, the demand response command may further include a zero demand response command (DR0). When the air conditioner receives a zero demand response command (DR0), it controls the air conditioner to exit the demand response mode.

[0074] In one embodiment of this application, the air conditioner can communicate with a terminal device (such as a mobile phone, tablet computer, smart wearable device, etc.). Users can select to enter or exit demand response mode via an app on the terminal device. When a user selects to enter demand response mode, the air conditioner will control its power consumption according to the demand response command, following the aforementioned steps. When a user inputs an exit command through the app, the air conditioner can exit demand response mode and resume normal operation.

[0075] In one embodiment of this application, during the power consumption control process of the air conditioner based on demand response commands, such as Figure 5 As shown, the control method for the air conditioner may further include the following steps S103 to S105:

[0076] Step S103: Obtain the indoor ambient temperature corresponding to the indoor unit of the air conditioner and the set temperature of the air conditioner.

[0077] Step S104: Compare the indoor ambient temperature with the set temperature to obtain the comparison result.

[0078] Step S105: Based on the comparison results and the air conditioner's operating mode, determine whether the air conditioner should exit demand response mode.

[0079] In this embodiment, the indoor ambient temperature and the set temperature of the air conditioner can be obtained. Based on the comparison between the indoor ambient temperature and the set temperature and the operating mode of the air conditioner, it is determined whether it is necessary to exit the demand response mode.

[0080] Specifically, such as Figure 6 As shown, step S105 may further include the following steps S1051 and S1052:

[0081] Step S1051: If the air conditioner is in heating mode and the difference between the set temperature and the indoor ambient temperature is greater than the preset maximum indoor temperature deviation, control the air conditioner to exit demand response mode.

[0082] Step S1052: If the air conditioner is in cooling mode and the difference between the indoor ambient temperature and the set temperature is greater than the maximum indoor temperature deviation, control the air conditioner to exit demand response mode.

[0083] In this embodiment, the maximum indoor temperature deviation can be preset by the user. For example, the user can set the maximum indoor temperature deviation on a terminal device that communicates with the air conditioner. The maximum indoor temperature deviation can also be a system default setting. The maximum indoor temperature deviation can be a non-negative integer, such as 0 degrees, 2 degrees, etc.

[0084] In heating mode, if the difference between the set temperature of the air conditioner and the indoor ambient temperature is greater than the maximum indoor temperature deviation, the air conditioner will be controlled to exit demand response mode.

[0085] In cooling mode, if the difference between the indoor ambient temperature and the air conditioner's set temperature is greater than the maximum indoor temperature deviation, the air conditioner will exit demand response mode.

[0086] Based on the methods described in steps S101 to S102 above, this embodiment of the application responds to a demand response command issued by a cloud server, obtains the total current value of the air conditioner, and performs power consumption control on the air conditioner according to the total current value and the demand response command. Through the above configuration method, this embodiment of the application can achieve power consumption control of the air conditioner based on the total current value after receiving a demand response command issued by the cloud service, thereby enabling the air conditioner to better meet the requirements of the US 1380-Demand Response (DR) standard.

[0087] The following is combined with Figures 7 to 9 The specific process of receiving a demand response command by an air conditioner according to an embodiment of this application will be described.

[0088] In one implementation, such as Figure 7 As shown, the indoor unit of the air conditioner is connected to the cloud server.

[0089] In one specific example, the indoor unit can communicate with the cloud server via Wi-Fi (mobile hotspot).

[0090] The indoor unit can receive demand response commands (DR) from the cloud server. The indoor unit then sends the demand response commands to the outdoor unit. Upon receiving the demand response commands, the outdoor unit can control the compressor to reduce its frequency based on the total current value, thereby controlling the power consumption of the air conditioner.

[0091] The demand response command can be sent to the outdoor unit through the communication interface between the indoor unit and the outdoor unit.

[0092] In a specific example, the communication interface can be an RS485 interface.

[0093] For multi-split air conditioners, which consist of one outdoor unit and multiple indoor units, one indoor unit can be selected as the master indoor unit. Based on the communication connection between the master indoor unit and the cloud server, after receiving a demand response command, the master indoor unit can send the command to the outdoor unit via the communication interface between the master indoor unit and the outdoor unit (e.g., an RS485 interface). Upon receiving the demand response command, the outdoor unit can control the compressor to reduce its frequency based on the total current value, thereby controlling the power consumption of the air conditioner. The specific control method for reducing the compressor frequency based on the total current value can be found in the aforementioned embodiments, and will not be repeated here for simplicity.

[0094] For multi-split air conditioners, in addition to the main indoor unit, the outdoor unit can send centralized control commands to the other indoor units, so that the other indoor units can determine whether they need to exit demand response mode based on the centralized control commands.

[0095] Specifically, after receiving the central control command, the indoor unit can obtain the indoor ambient temperature and the air conditioner's set temperature, compare the indoor ambient temperature with the set temperature, and obtain the comparison result; based on the comparison result, it can determine whether to exit the demand response mode.

[0096] When the indoor unit determines that it needs to exit demand response mode based on the comparison results, or when the indoor unit receives a demand response exit command from the cloud server, the indoor unit can send a demand response exit command to the outdoor unit to exit demand response mode.

[0097] In another implementation, for air conditioners where the indoor and outdoor units cannot communicate, such as... Figure 8 As shown, an air conditioner may include a central controller, an indoor unit, and an outdoor unit. The central controller communicates with a cloud server. It can receive demand response commands from the cloud server. The central controller can send these demand response commands to the outdoor unit, enabling the outdoor unit to control the air conditioner's power consumption accordingly. Specifically, the demand response commands can be sent to the outdoor unit via a communication interface between the indoor and outdoor units.

[0098] In a specific example, the communication interface can be an RS485 interface.

[0099] The system can obtain the indoor ambient temperature and the air conditioner's set temperature from the central controller. Based on these two temperatures, it can determine whether the air conditioner needs to exit demand response mode. Specifically, the indoor ambient temperature and the set temperature can be compared. Based on the comparison result and the air conditioner's operating mode, it can be determined whether the air conditioner needs to exit demand response mode. For example, if the air conditioner is operating in heating mode and the difference between the set temperature and the indoor ambient temperature is greater than the preset maximum indoor temperature deviation, the air conditioner is determined to exit demand response mode. If the air conditioner is operating in cooling mode and the difference between the indoor ambient temperature and the set temperature is greater than the maximum indoor temperature deviation, the air conditioner is determined to exit demand response mode.

[0100] If it is determined that the air conditioner needs to exit demand response mode, or if the central controller receives a demand response exit command from the cloud server, the central controller can send a demand response exit command to the outdoor unit to exit demand response mode.

[0101] In the third embodiment, for air conditioners where the indoor and outdoor units cannot communicate, such as... Figure 9 As shown, an air conditioner may include an indoor unit and an outdoor unit. A communication module may be installed on the outdoor unit. The outdoor unit can communicate with a cloud server through this module. It can receive demand response commands from the cloud server via the outdoor unit's communication module. The outdoor unit can then control the air conditioner's power consumption based on these demand response commands.

[0102] In a specific example, the communication module can be a 4G (the 4th generation mobile communication technology) communication module.

[0103] Specifically, the indoor unit can obtain the total current value of the air conditioner and control the compressor of the outdoor unit to reduce its frequency based on the total current value, so as to achieve power consumption control of the air conditioner.

[0104] After receiving a demand response command, the outdoor unit can send a centralized control command to the indoor unit, allowing the indoor unit to determine whether to withdraw from the demand response command based on the centralized control command. The centralized control command can be sent to the indoor unit through the communication interface between the indoor and outdoor units.

[0105] In a specific example, the communication interface can be an RS485 interface.

[0106] Specifically, in response to a central control command, the indoor unit can acquire the indoor ambient temperature and the air conditioner's set temperature. Based on these two temperatures, it determines whether to exit the demand response mode. Specifically, the indoor ambient temperature and the set temperature can be compared. Based on the comparison result and the air conditioner's operating mode, it is determined whether the air conditioner needs to exit the demand response mode. For example, if the air conditioner is operating in heating mode and the difference between the set temperature and the indoor ambient temperature is greater than the preset maximum indoor temperature deviation, the air conditioner is determined to exit the demand response mode. If the air conditioner is operating in cooling mode and the difference between the indoor ambient temperature and the set temperature is greater than the maximum indoor temperature deviation, the air conditioner is determined to exit the demand response mode.

[0107] If it is determined that the air conditioner needs to exit demand response mode, or if the outdoor unit receives a demand response exit command from the cloud server, the outdoor unit can exit demand response mode.

[0108] Through the above configuration, this embodiment of the application receives demand response commands from the cloud server based on the communication module installed on the outdoor unit, and controls the outdoor unit to control the power consumption of the air conditioner according to the demand response commands. Based on this, this embodiment of the application can realize the communication connection between the communication module of the outdoor unit and the cloud server, thereby obtaining demand response commands. The outdoor unit controls the power consumption of the air conditioner according to the demand response commands, thereby enabling the air conditioner to better meet the requirements of the US 1380-Demand Response (DR) standard.
