Description

Technical Field

[0001] The present disclosure relates to the field of smart home technology, and in particular to a control method, system, air conditioner, device and medium for an air conditioner. Background Art

[0002] As energy-saving requirements continue to increase, the demand for peak-shifting response in the power grid is also becoming higher and higher. For example, the purpose of energy consumption control can be achieved by limiting the output of the outdoor unit of the air conditioner and the set temperature of the indoor unit.

[0003] However, during the peak-shifting response of the power grid, the set temperature of the indoor unit and the output of the outdoor unit of the air conditioner are usually controlled according to the peak-shifting demand index, which may easily lead to large temperature changes in the process of energy-saving control of the air conditioner (such as temperature rise in cooling mode, such as temperature drop in heating mode), thereby reducing comfort. In addition, when the indoor temperature cannot meet the user's needs, the energy-saving response state will be jumped out and the indoor temperature control will be prioritized. In this way, the indoor temperature may fluctuate in a large range, which may cause the air conditioner to repeatedly switch between different states, and thus not only cannot meet the comfort requirements well, but the frequent switching will also affect the user experience of the air conditioner.

[0042] The present application is further described in detail below in conjunction with the embodiments and drawings. It is to be understood that the specific embodiments described herein are only used to explain the relevant application, rather than to limit the application. It is also necessary to explain that, for ease of description, only the parts related to the application are shown in the drawings.

[0043] It should be noted that, in the absence of conflict, the embodiments of the present application, that is, the features of the embodiments, can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0044] The following describes in detail the control method, system, air conditioner, device and medium of the air conditioner according to the embodiments of the present application in conjunction with the accompanying drawings.

[0045] Before describing the control method of the air conditioner in the embodiment of the present invention, the air conditioner is first explained. The air conditioner, that is, the air conditioning system, usually includes two parts: an indoor unit and an outdoor unit. Of course, it can also be an integrated indoor and outdoor unit air conditioner, that is, the indoor unit and the outdoor unit are integrated. The air conditioner includes a compressor, an evaporator, a condenser, a throttling component, etc., and the compressor, evaporator, condenser, throttling component, etc. constitute the refrigeration system of the air conditioner. Of course, the air conditioner in the embodiment of the present application can also refer to a heat pump system that can both cool and cool. The air conditioner usually also includes a four-way valve, which controls the direction of the condenser so that the heat pump system can operate in heating or cooling mode.

[0046] Figure 1 FIG. 1 is a flow chart of a method for controlling an air conditioner according to an embodiment of the present application. Figure 1 As shown, a method for controlling an air conditioner according to an embodiment of the present application includes the following steps:

[0047] S101: When the operation state of the air conditioner enters the energy consumption reduction response state, the indoor temperature is obtained.

[0048] In a specific example, when the air conditioner is operating normally according to the user's setting, if a power reduction command is received, the operating state of the air conditioner is switched to the power reduction response state, and after entering the power reduction response state, the indoor temperature is obtained in real time. The operating state of the air conditioner when operating normally according to the user's setting can be named the normal operating state. That is, when the air conditioner is in the normal operating state, if a power reduction command is received, it is switched from the normal operating state to the power reduction response state. The way to obtain the indoor temperature is that the air conditioner can detect the indoor temperature through the built-in temperature sensor, that is, the ambient temperature of the room where the indoor unit of the air conditioner is located.

[0049] In this example, the operating state of the air conditioner includes an energy-reduction response state and a non-energy-reduction response state, wherein the non-energy-reduction response state refers to other operating states except the energy-reduction response state, such as a normal operating state.

[0050] The energy consumption reduction response state can be achieved by receiving an energy consumption response command sent from the outside, so that the air conditioner's operating state enters the energy consumption reduction response state. For example: according to the increasing demand for peak-shifting response of the power grid, an energy consumption response command issued by the power grid will be received during a certain period of time.

[0051] The air conditioner may include a communication module for communicating with the outside, and receive the energy consumption response command issued by the power grid through the communication module. The communication module generally refers to a network interconnection device that can access the Internet.

[0052] In the above description, the energy consumption reduction response state refers to an operating mode that reduces the energy consumption of the air conditioner. For example, as the demand for peak-shifting response of the power grid increases, it is usually necessary to ensure that the air conditioner can achieve sufficient peak-shifting response effect. In the energy consumption reduction response state, the output of the outdoor unit of the air conditioner can be directly limited, for example, reducing the compressor frequency of the outdoor unit, the wind speed of the outdoor unit, etc., so that the overall energy consumption of the air conditioner reaches the corresponding index, for example, it is necessary to reach a target value for energy consumption reduction, that is, the actual power of the air conditioner needs to be reduced to a certain extent to reduce the overall energy consumption of the air conditioner to the target value for energy consumption reduction. Of course, in some scenarios, it may be difficult to achieve this indicator for the control of the outdoor unit. For example, when the user has more stringent requirements for the indoor environment and the indoor unit of the air conditioner consumes more energy. The purpose of reducing energy consumption can also be achieved by adjusting the set temperature.

[0053] S102: Determine whether the comfort index is met according to the indoor temperature.

[0054] In one embodiment of the present invention, judging whether the comfort index is met according to the current indoor temperature may specifically include: obtaining the comfort control index temperature and the hysteresis control temperature; obtaining the comfort threshold temperature according to the set temperature of the air conditioner and the comfort control index temperature; obtaining the comfort transition temperature according to the set temperature of the air conditioner, the comfort control index temperature and the hysteresis control temperature; finally, determining whether the comfort index is met according to the relationship between the indoor temperature and the comfort threshold temperature and the comfort transition temperature.

[0055] Among them, the comfort control index temperature and the hysteresis control temperature can be preset, and the comfort control index temperature refers to the comfort control index, which is usually set to any temperature value between 0℃ and 5℃. The hysteresis control temperature can effectively prevent the air conditioner from frequently switching between different states, and usually, it can be set to any temperature value between 0.5℃ and 3℃.

[0056] It should be noted that when the air conditioner is cooling or heating, the comfort threshold temperature is determined in different ways according to the air conditioner's set temperature and the comfort control index temperature; the comfort transition temperature is determined in different ways based on the air conditioner's set temperature, the comfort control index temperature, and the hysteresis control temperature; and the way to determine whether the comfort index is met is also different based on the size relationship between the indoor temperature and the comfort threshold temperature and the comfort transition temperature. The following describes how to determine the comfort threshold temperature, the comfort transition temperature, and whether the comfort index is met in the two operating modes of the air conditioner in the cooling mode and the heating mode.

[0057] Taking the cooling mode as an example, when the air conditioner is in cooling mode, assuming that T1 is the indoor temperature, Ts is the set temperature, that is, the indoor set temperature, ΔT_DRcool is the comfort control index temperature, and A is the hysteresis control temperature. Then: according to the relationship between the indoor temperature T1 and the comfort threshold temperature and the comfort transition temperature, determine whether the comfort index is met, which can specifically include:

[0058] (1) If the indoor temperature T1 is lower than the comfort transition temperature, it is determined that the comfort index is satisfied. In this example, the comfort transition temperature = the set temperature Ts of the air conditioner + the comfort control index temperature ΔT_DRcool - the hysteresis control temperature A.

[0059] That is: comfort transition temperature = Ts + ΔT_DRcool – A. If T1 < Ts + ΔT_DRcool – A, it is determined that the comfort index is met.

[0060] (2) If the indoor temperature T1 is greater than or equal to the comfort transition temperature and is less than the comfort threshold temperature, it is determined to be close to the comfort index. In this example, the comfort threshold temperature = the set temperature TS of the air conditioner + the comfort control index temperature ΔT_DRcool.

[0061] That is, if Ts+ΔT_DRcool−A≤T1<TS+ΔT_DRcool, it is judged to be close to the comfort index.

[0062] (3) If the indoor temperature T1 is greater than or equal to the comfort threshold temperature, it is judged that the comfort index is not met.

[0063] That is, if T1≥TS+ΔT_DRcool, it is determined that the comfort index is not satisfied.

[0064] In specific applications, taking cooling as an example, when the indoor temperature T1 is far from the comfort index, that is: T1<Ts+ΔT_DRcool–A℃, it means that the current comfort level in the room is very high and meets the comfort index. In other words, the cooling can easily reach the user-set temperature and can easily meet the user's cooling needs. Therefore, in this case, the air conditioner is allowed to execute the energy-reducing response state, that is, the air conditioner is allowed to execute the energy-reducing control; and as the energy-reducing control proceeds, it will move more and more towards the direction of failing to meet the user's cooling needs, that is: the indoor temperature T1 will usually increase gradually. When the indoor temperature is already close to When the comfort index is met, that is: Ts+ΔT_DRcool–A≤T1<Ts+ΔT_DRcool, it means that it is in a state close to the comfort index. At this time, it is necessary to restrict the air conditioner from further energy reduction control, for example: prohibiting the air conditioner compressor from further reducing the frequency, prohibiting the reduction of the wind speed, and other controls that reduce the air conditioner refrigeration output capacity; if the comfort index cannot be met, that is: Ts+ΔT_DRcool≤T1, it enters a special state of energy reduction response, that is: restore the normal cooling of the air conditioner, that is, give priority to comfort control according to the set temperature to ensure that the cooling demand can be met.

[0065] It should be noted that when the air conditioner is in cooling mode, after entering the special state of energy reduction response, it will not exit this state until the corresponding exit condition of the special state of energy reduction response is met. Otherwise, in this state, while giving priority to comfort control according to the set temperature to ensure that the cooling demand can be met, it will no longer respond to energy reduction commands. That is to say, in this state, even if an energy reduction command is received, it will not respond to the energy reduction command.

[0066] In another example, taking the heating mode as an example, when the air conditioner is in the heating mode, assuming that T1 is the indoor temperature, Ts is the set temperature, that is, the indoor set temperature, ΔT_DRheat is the comfort control index temperature, and B is the hysteresis control temperature. Then: according to the relationship between the indoor temperature T1 and the comfort threshold temperature and the comfort transition temperature, it is determined whether the comfort index is met, which may specifically include:

[0067] (1) If the indoor temperature T1 is greater than the comfort level transition temperature, it is determined that the comfort level index is satisfied. In this example, the comfort level transition temperature = the air conditioner set temperature Ts - the comfort level control index temperature ΔT_DRheat + the hysteresis control temperature B.

[0068] That is: comfort transition temperature = Ts - ΔT_DRheat + B. If T1 > Ts - ΔT_DRheat + B, it is determined that the comfort index is met.

[0069] (2) If the indoor temperature T1 is less than or equal to the comfort transition temperature, and the indoor temperature T1 is greater than the comfort threshold temperature, it is determined to be close to the comfort index. In this example, the comfort threshold temperature = the set temperature TS of the air conditioner - the comfort control index temperature ΔT_DRheat.

[0070] That is, if Ts-ΔT_DRheat<T1≤Ts-ΔT_DRheat+B, it is judged to be close to the comfort index.

[0071] (3) If the indoor temperature T1 is less than or equal to the comfort threshold temperature, it is judged that the comfort index is not met.

[0072] That is, if T1≤TS-ΔT_DRheat, it is determined that the comfort index is not met.

[0073] In a specific application, taking heating as an example, when the indoor temperature T1 is far from the comfort index, that is: T1>Ts-ΔT_DRheat+B℃, it means that the current comfort level in the room is very high and meets the comfort index. In other words, heating can easily reach the user-set temperature and can easily meet the user's heating needs. Therefore, in this case, the air conditioner is allowed to execute the energy-reducing response state, that is, the air conditioner is allowed to execute the energy-reducing control; and as the energy-reducing control proceeds, it will move more and more towards the direction of failing to meet the user's heating needs, that is: the indoor temperature T1 will usually decrease gradually. When the indoor temperature is already close to the comfort index, the air conditioner will be cooled. When the comfort index is met, that is: Ts-ΔT_DRheat<T1≤Ts-ΔT_DRheat+B, it means that the state is close to the comfort index. At this time, it is necessary to restrict the air conditioner from further energy-saving control, for example: prohibiting the air conditioner compressor from further reducing the frequency, prohibiting the reduction of the wind speed, prohibiting the shutdown of the electric auxiliary heating, etc., which will reduce the air conditioner heating output capacity; if the comfort index cannot be met, that is: T1≤TS-ΔT_DRheat, then enter the special state of energy-saving response, that is: restore the normal heating of the air conditioner, that is, give priority to comfort control according to the set temperature to ensure that the cooling demand can be met.

[0074] It should be noted that when the air conditioner is in heating mode, after entering the special state of energy reduction response, it will not exit this state until the corresponding exit condition of the special state of energy reduction response is met. Otherwise, in this state, while giving priority to comfort control according to the set temperature to ensure that the heating demand can be met, it will not respond to energy reduction commands. That is to say, in this state, even if an energy reduction command is received, it will not respond to the energy reduction command.

[0075] S103: If it is determined that the indoor temperature does not meet the comfort index, the operating state of the air conditioner is controlled to switch from the energy reduction response state to the energy reduction response special state, wherein after the operating state of the air conditioner enters the energy reduction response special state from the energy reduction response state, the air conditioner operation is preferentially controlled according to the comfort index until the exit condition of the energy reduction response special state is met.

[0076] That is, after entering the special state of energy-saving response, the normal cooling or heating mode is used according to the set temperature to make the indoor temperature close to the set temperature, thereby meeting the comfort index. For example, according to the difference between the set temperature TS and the current indoor temperature T1, the cooling or heating is performed normally without considering the energy consumption, so that the current indoor temperature T1 can be close to the set temperature TS, thereby meeting the normal cooling or heating needs of the user. In this state, if the energy-saving command is received again, the energy-saving command is not responded to, and the cooling or heating is performed with the priority of meeting the user's comfort.

[0077] In one embodiment of the present invention, the energy consumption reduction response special state exit condition is satisfied, and at least one of the following conditions is included, that is, when at least one of the following conditions is satisfied, the energy consumption reduction response special state is exited:

[0078] (1) receiving a command to cancel energy reduction;

[0079] (2) receiving other peak reduction commands other than the energy consumption reduction command;

[0080] (3) The duration of the special state of energy consumption reduction response reaches the predetermined time.

[0081] That is to say, after entering the special state of energy consumption reduction response, if a command to cancel energy consumption reduction is received, that is, the air conditioner no longer needs to be controlled to reduce energy consumption, the special state of energy consumption reduction response can be exited and the normal operation state can be switched. Alternatively, when other peak reduction commands other than the energy consumption reduction command are received, other peak reduction commands are responded to, and the air conditioner operation is controlled according to the requirements of other peak reduction commands. Alternatively, when the duration of the special state of energy consumption reduction response reaches a predetermined time, the special state of energy consumption reduction response is automatically exited, wherein the predetermined time can be any time from 0.5 hours to 24 hours, for example, if it is set to 4 hours, the special state of energy consumption reduction response is automatically exited after 4 hours.

[0082] Since the energy-saving response is in a special state, the air conditioner will no longer respond to the energy-saving command, but will control the air conditioner operation with comfort as the priority. This can avoid frequent switching of the air conditioner in different operating states.

[0083] For example: In the related art, when the air conditioner is in a normal operating state, if it receives an energy consumption reduction response command, it enters the energy consumption reduction response state and controls the air conditioner to reduce energy consumption. As the process continues, the indoor temperature may not meet the needs of the user. At this time, it will automatically switch to the normal operating state to make the temperature better meet the user's needs. After the indoor temperature meets the user's needs, it will switch to the energy consumption reduction response state again. The indoor temperature fluctuates over a large range, resulting in frequent switching between the two operating states, which not only affects the user's comfort, but also causes the frequent switching of the operating state to fail to better meet the energy consumption reduction needs.

[0084] However, by using the method of the embodiment of the present invention, when the comfort requirements are not met, the energy-reducing response special state is entered. In this state, the energy-reducing response state or the normal operation state can be switched only after receiving a command to cancel the energy-reducing response, or receiving other peak-shaving commands other than the energy-reducing response, or the duration of the energy-reducing response special state reaches, for example, 4 hours. In this way, the system can run for a long time in a state such as the energy-reducing response special state, avoiding frequent switching of different operation states due to temperature fluctuations. Furthermore, it can not only better meet the user's comfort requirements, but also effectively avoid frequent switching of different operation states that affects the user experience of the air conditioner. That is, the user experience of the air conditioner is effectively improved.

[0085] According to the control method of the air conditioner of the embodiment of the present invention, during the operation of the air conditioner in the energy-reducing response state, it is determined in real time based on the indoor temperature whether the comfort index is met. When the comfort index is not met, it is switched to the special state of energy-reducing response and maintained in this state for continuous operation, thereby controlling the air conditioner with comfort as the priority. In this way, it can operate for a long time in the special state of energy-reducing response, avoiding frequent switching of different operating states caused by temperature fluctuations. Furthermore, it can not only better meet the user's comfort, but also effectively avoid frequent switching of different operating states that affects the use experience of the air conditioner.

[0086] In one embodiment of the present invention, when the comfort index is met, the control method of the air conditioner may further include: maintaining the operating state of the air conditioner as an energy reduction response state until the exit condition of the energy reduction response state is met; when the comfort index is close to the comfort index, the control method of the air conditioner may further include: limiting the energy reduction control of the air conditioner until the restriction exit condition is met. For example, taking the cooling mode as an example, when the air conditioner is operating in the energy-reducing response state, the comfort index is always met, that is, when T1 is less than Ts+ΔT_DRcool–A, for example, if no cancellation of the energy-reducing response instruction is received, the air conditioner is maintained in this state to achieve the purpose of reducing energy consumption and meet the peak shifting requirements of the power grid; when the air conditioner is operating in the energy-reducing response state, if it has slowly reached a level close to the comfort index, that is, when Ts+ΔT_DRcool–A≤T1<TS+ΔT_DRcool, the air conditioner is restricted from further energy-reducing control, for example, the air conditioner compressor is prohibited from further reducing the frequency, the wind speed is prohibited from being lowered, and other controls that reduce the air conditioning output capacity, thereby avoiding further increases in indoor temperature and further decreases in comfort, thereby achieving a balance between reducing energy consumption and satisfying user comfort.

[0087] Through the above steps S101 to S103, frequent switching of different operating states caused by temperature fluctuations can be avoided. As a specific application, combined with Figure 2 As shown, during the normal operation of the system (i.e., the air conditioner), if an energy reduction command is received, the system enters an energy reduction response state and operates. During operation in this state, it continuously determines whether the current comfort index meets the standard. If so, the energy reduction control is continued until the exit condition of the energy reduction response state is reached. If it is determined that the current comfort index does not meet the standard, for example, when it is close to the comfort index, the energy reduction control is no longer responded to but the energy reduction control of the air conditioner is restricted. During this process, if the indoor temperature does not deteriorate (such as the indoor temperature does not continue to rise in cooling mode, and the indoor temperature does not continue to drop in heating mode), the operation is maintained in this state. If the indoor temperature continues to deteriorate, that is, when the comfort index is not met, the energy reduction response special state is entered to improve the comfort and maintain it until a certain period of time has passed or a command to cancel the energy reduction response is received, that is, when condition B or condition C is met. As a result, it can run for a long time in a special state of energy-saving response, avoiding frequent switching of different operating states caused by temperature fluctuations. Furthermore, it can not only better meet the user's comfort, but also effectively avoid frequent switching of different operating states affecting the user experience of the air conditioner.

[0088] When the system enters the energy reduction response state, if the exit condition is met, such as condition A, it will switch back to the normal operation state. Among them, conditions A and B are but not limited to: receiving a cancel energy reduction response command, or receiving other peak shaving commands, or after a period of time, the time can usually be selected between 0.5 hours and 24 hours. Condition C is receiving other peak shaving commands, or after a period of time, the time can usually be selected between 0.5 hours and 24 hours.

[0089] Figure 3 FIG. 1 is a structural block diagram of an air conditioning control system according to an embodiment of the present application. Figure 3 As shown, the air conditioner control system according to an embodiment of the present application includes: an acquisition module 310, a judgment module 320 and a control module 330, wherein:

[0090] The acquisition module 310 is used to obtain the indoor temperature when the operation state of the air conditioner enters the energy consumption reduction response state;

[0091] A judgment module 320, used to judge whether the comfort index is met according to the indoor temperature;

[0092] The control module 330 is used to control the operating state of the air conditioner to switch from the energy reduction response state to the energy reduction response special state when the judgment module 320 determines that the comfort index is not met, wherein, in the energy reduction response special state, the air conditioner is controlled to operate according to the comfort index until the exit condition of the energy reduction response special state is met.

[0093] According to the control system of the air conditioner of the embodiment of the present invention, when the air conditioner is running in the energy-reducing response state, it is judged in real time based on the indoor temperature whether the comfort index is met. When the comfort index is not met, it will switch to the special state of energy-reducing response and maintain continuous operation in this state, so as to control the air conditioner with comfort as the priority. In this way, it can run for a long time in the special state of energy-reducing response, avoiding frequent switching of different operating states caused by temperature fluctuations. Furthermore, it can not only better meet the user's comfort, but also effectively avoid frequent switching of different operating states to affect the use experience of the air conditioner.

[0094] For the specific definition of the control system of the air conditioner, please refer to the definition of the control method of the air conditioner above, which will not be repeated here. The various modules of the control system of the air conditioner can be implemented in whole or in part by software, hardware and a combination thereof.
