Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air conditioners, in particular to a control method of an air conditioner and the air conditioner. BACKGROUND

[0002] The large-scale use of air conditioners in high-temperature weather in summer is the main reason for power supply tension in summer. At present, there are some problems in the way of dealing with power supply tension in summer. For example, during the peak period of electricity consumption, the existing power tension relief means is usually concentrated on the supply side, which is manifested as artificial control of power distribution by the power transmission system, such as artificial power outage, time-limited electricity, peak-shaving electricity, etc. This control means is neither flexible nor humanized. Even in the case of introducing demand response mechanism, it still cannot be accurately controlled to the specific appliance level and cannot control the key appliances. For example, if the air conditioner and other household appliances can be accurately controlled to execute demand response during the peak period of electricity consumption in summer, the normal use of the refrigerator and other household appliances in the family will not be affected, the power tension can be relieved to the minimum, and the key appliances can be accurately controlled. Moreover, in the case of introducing demand response mechanism to the air conditioner, there is still a lack of control logic for special processing of individual functions of different air conditioners.

[0052] In the description of this embodiment, the terms "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0053] Figure 1 This is a schematic flowchart of an air conditioner control method according to an embodiment of the present invention, such as... Figure 1 As shown, for reference Figures 2 to 4 This invention provides a method for controlling an air conditioner, comprising the following steps:

[0054] Step S1: After receiving the demand response command, obtain the operating status of the compressor.

[0055] Step S2: If the compressor is working, obtain the air conditioner's set temperature and / or air conditioner's operating mode.

[0056] Step S3: According to the set temperature and / or air conditioner operation mode, it is judged whether the air conditioner enters the demand response state.

[0057] Specifically, demand response refers to the behavior of temporarily changing the user's inherent power consumption mode to adjust the power consumption when the power system safety and reliability is at risk, so as to promote the balance between power supply and demand and ensure the stable operation of the system. Through the implementation of demand response, users can be guided to improve the level of load management refinement, achieve peak load shifting, and effectively alleviate the contradiction between power supply and demand.

[0058] The demand response instruction refers to the demand response instruction issued by the upper computer to the air conditioner. After receiving the demand response instruction, the air conditioner will determine whether to enter the demand response state according to the set temperature and operation mode of the air conditioner when the compressor is working.

[0059] For example, the upper computer issues a forced demand response instruction to the air conditioner. The air conditioner is usually equipped with a WiFi module for connecting to the home network and accessing the whole-house smart home appliance system. In an apartment building, there is usually a home appliance control system, such as a hotel's back-end monitoring system for guest room electrical equipment. Such a system can be used as an upper computer to issue demand response instructions from the upper computer to the lower computer. During the period of tight electricity consumption, the upper computer issues demand response instructions to the controlled lower computer according to the upper demand. The air conditioner as a lower computer receives the instruction, and the air conditioner determines whether to enter the demand response state according to the set temperature and operation mode of the air conditioner.

[0060] In this embodiment, the "set temperature" and "air conditioner operation mode" are used as the judgment conditions for whether the air conditioner enters the demand response state. Using the "air conditioner operation mode" as one of the judgment conditions for whether the air conditioner enters the demand response state allows the air conditioner to enter different demand response states according to different air conditioner operation modes.

[0061] Alternatively, the "set temperature" is used as the judgment condition for whether the air conditioner enters the demand response state, allowing the air conditioner to enter different demand response states according to different set temperatures.

[0062] Alternatively, the "air conditioner operation mode" is used as the judgment condition for whether the air conditioner enters the demand response state, allowing the air conditioner to enter different demand response states according to different air conditioner operation modes.

[0063] On the one hand, the present application can alleviate the problem of tight power supply and achieve the effect of saving electricity. On the other hand, when the compressor is working, the set temperature and operation mode of the air conditioner are used to determine whether to enter the demand response state, so that the air conditioner can be precisely powered down to minimize the negative impact.

[0064] Further, the application can correspond to different demand response states according to different air conditioner operation modes, save electricity while maintaining the functions corresponding to the air conditioner operation modes.

[0065] In some embodiments of the application, determining whether the air conditioner enters the demand response state according to the set temperature and / or the air conditioner operation mode includes: in response to the air conditioner operation mode being the normal mode or the special mode, determining whether the set temperature meets the preset condition. If the preset condition is met, the air conditioner enters the demand response state.

[0066] In this embodiment, the air conditioner operation mode includes the normal mode and the special mode. When the air conditioner operation mode is the normal mode or the special mode, the air conditioner determines the relationship between the set temperature and the preset condition; if the set temperature meets the preset condition, the air conditioner enters the demand response state. When the air conditioner operation mode or the set temperature is different, the air conditioner enters different demand response states.

[0067] The application takes the air conditioner operation mode as one of the judgment conditions, so that the air conditioner can enter different demand response states in different air conditioner operation modes, save electricity while maintaining the functions corresponding to the air conditioner operation modes, such as the sleep mode corresponding to no sound, thereby avoiding reducing the user experience.

[0068] In some embodiments of the application, the preset condition includes a first preset condition, and the demand response state includes a first demand response state. Figure 2

[0069] If the preset condition is met, the air conditioner enters the demand response state, including:

[0070] If the set temperature is less than the first preset temperature and greater than or equal to the second preset temperature, the first preset condition is met, and the air conditioner enters the first demand response state.

[0071] The first demand response state includes the following steps:

[0072] Step S11: Assigning the set temperature to a first set value.

[0073] Step S12: Controlling the compressor and the outdoor fan to operate according to the first mode and repeating multiple cycles, the first mode including: after the compressor and the outdoor fan are stopped for a first preset time, the compressor and the outdoor fan are restarted and operated for a second preset time.

[0074] Step S13: When the cumulative time length of the first mode cycle operation reaches a first set time length, the air conditioner exits the first demand response state.

[0075] ​In the embodiment, the condition that the set temperature is less than the first preset temperature and greater than or equal to the second preset temperature is used as the judgment condition for the set temperature satisfying the first preset condition. The first preset temperature is greater than the second preset temperature, and the first preset temperature and the second preset temperature can be set according to actual conditions. The first set value, the first preset time length, the second preset time length, and the cumulative time length can be set according to actual conditions, and the cumulative time length is greater than the first preset time length and the second preset time length.

[0076] Specifically, the first demand response state is that the air conditioner forcibly assigns the set temperature to the first set value, and then controls the compressor and the outdoor fan to operate in the first mode and repeat multiple times, until the cumulative time length of the first mode repetition reaches the first set time length, the air conditioner exits the first demand response state. The first mode refers to that the compressor and the outdoor fan are stopped for a first preset time length, and then the compressor and the outdoor fan are restarted and run for a second preset time length. That is, the compressor and the outdoor fan are stopped for a period of time, and then started and run for a period of time. During the cycle operation of the compressor and the outdoor fan in the first mode, the set indoor fan speed is unchanged, and the outdoor fan speed when operating is unchanged.

[0077] In the embodiment, the air conditioner forcibly assigns the set temperature to the first set value, and the compressor and the outdoor fan are stopped for a first preset time length, which is a measure to alleviate power supply tension, achieving the effect of saving electricity; and the compressor and the outdoor fan are restarted and run for a second preset time length, which can allow the air conditioner to continue refrigeration, maintain the refrigeration effect in the room, and avoid reducing the user experience.

[0078] In some embodiments of the present application, the preset condition includes a second preset condition, and the demand response state includes a second demand response state. Figure 3

[0079] If the preset condition is met, the air conditioner is controlled to enter the demand response state, including that when the set temperature is less than the second preset temperature, the second preset condition is met, and the air conditioner enters the second demand response state.

[0080] The second demand response state includes the following steps:

[0081] Step S21: assigning the set temperature to the second set value.

[0082] Step S22: controlling the compressor and the outdoor fan to operate in the second mode and repeat multiple cycles, and the second mode is that the compressor and the outdoor fan are stopped for a third preset time length, and then the compressor and the outdoor fan are restarted and run for a fourth preset time length.

[0083] Step S23: when the cumulative time length of the second mode cycle operation reaches the second set time length, the air conditioner exits the second demand response state.

[0084] ​In the embodiment, the condition that the set temperature is less than the second preset temperature is used as the judgment condition for satisfying the second preset condition. The second preset temperature, the second set value, the third preset time length, the fourth preset time length, and the second set time length can be set according to actual conditions. The cumulative time length of the second mode cycle operation is greater than the third preset time length and the fourth preset time length.

[0085] Specifically, the second demand response state is that the air conditioner forcibly assigns the set temperature to the second set value, and then the air conditioner controls the compressor and the outdoor fan to operate in the second mode and repeats multiple times. When the cumulative time length of the second mode repeated multiple times reaches the second set time length, the air conditioner exits the second demand response state. The second mode is that the compressor and the outdoor fan are stopped for the third preset time length, and then the compressor and the outdoor fan are restarted and operated for the fourth preset time length. During the cycle operation of the compressor and the outdoor fan in the second mode, the set indoor fan speed is unchanged, and the outdoor fan speed when operating is unchanged.

[0086] Correspondingly, the first preset time length and the second preset time length in step S12 can be the same as or different from the third preset time length and the fourth preset time length in the embodiment, and can be set according to actual conditions.

[0087] In the embodiment, the air conditioner forcibly assigns the set temperature to the second set value and the compressor and the outdoor fan are stopped for the third preset time length, which are measures to alleviate the power supply tension and achieve the effect of saving electricity; and the compressor and the outdoor fan are restarted and operated for the fourth preset time length, which can make the air conditioner continue to cool and maintain the cooling effect in the room, avoiding reducing the user experience.

[0088] In some embodiments of the application, when the set temperature of the air conditioner is greater than the first preset temperature, the demand response instruction issued by the upper computer is ignored, and the demand response state is not entered. When the set temperature of the air conditioner is greater than the first preset temperature, the set power saving requirement of the air conditioner is met, and the air conditioner does not enter the demand response state.

[0089] In some optional embodiments of the application, when the air conditioner is in the air supply mode, the compressor does not work at this time, and the air conditioner ignores the demand response instruction issued by the upper computer and does not enter the demand response state. The current state of the air conditioner meets the set power saving requirement of the air conditioner, and there is no need to enter the demand response state.

[0090] In some embodiments of the application, the special mode includes a sleep mode and a timing shutdown mode, and the normal mode includes a cooling mode and a dehumidification mode.

[0091] In the embodiment, the special mode includes but is not limited to the sleep mode and the timing shutdown mode, and the normal mode includes but is not limited to the cooling mode and the dehumidification mode. The special mode and the normal mode in the embodiment both need the compressor to work.

[0092] The special mode has a special function, for example, the sleep mode has no sound and no light; the timing shutdown mode shuts down at the set time. When the air conditioner is in the special mode, the air conditioner selects different demand response states according to the special mode and adopts different measures.

[0093] In some embodiments of the present application, whether the air conditioner enters the demand response state is determined according to the set temperature and / or the air conditioner operation mode, including the following steps:

[0094] When the air conditioner operation mode is the sleep mode and the set temperature meets the preset condition, the set duration, the running duration and the remaining duration of the sleep mode of the demand response state are obtained.

[0095] When the remaining duration is less than the set duration, the air conditioner enters the demand response state; and during the running of the demand response state, when the running duration of the demand response state is less than or equal to the remaining duration, the air conditioner does not perform the prompt operation, and when the running duration of the demand response state is greater than the remaining duration, the air conditioner performs the special identification display operation.

[0096] When the remaining duration is greater than or equal to the set duration, the air conditioner enters the demand response state and does not perform the prompt operation. The prompt operation includes the special identification display operation.

[0097] In the present embodiment, the prompt operation includes but is not limited to the special identification display operation, voice prompt, LED flashing prompt, and the special identification display operation includes intelligent screen display and remote control display, which is determined by the actual function of the air conditioner. When the air conditioner operation mode of the air conditioner is the sleep mode and the set temperature meets the preset condition, the air conditioner enters the demand response state and performs different operations according to the relationship among the set duration, the running duration and the remaining duration of the sleep mode of the demand response state.

[0098] When the remaining duration is less than the set duration, the air conditioner enters the demand response state, and during the running of the demand response state, when the running duration of the demand response state is less than or equal to the remaining duration, the air conditioner does not perform the prompt operation to avoid disturbing the user's sleep; when the running duration of the demand response state is greater than the remaining duration, the air conditioner performs the special identification display operation to prompt that the air conditioner is in the demand response state, but does not perform other prompt operations to avoid disturbing the user's sleep.

[0099] When the remaining duration of the sleep mode is greater than or equal to the set duration of the demand response state, the air conditioner enters the demand response state and does not perform the prompt operation. The air conditioner does not disturb the user during the whole process of the sleep mode and the demand response state.

[0100] Correspondingly, when the air conditioner is in the sleep mode, the air conditioner enters the first demand response state or the second demand response state according to the preset condition satisfied by the set temperature; the set duration of the demand response state in the embodiment includes the first set duration in the step S13 and the second set duration in the step S23.

[0101] When the air conditioner is in the sleep mode, the air conditioner enters the first demand response state or the second demand response state according to the preset condition satisfied by the set temperature; the set duration of the demand response state in the embodiment includes the first set duration in the step S13 and the second set duration in the step S23.

[0102] When the air conditioner is in the sleep mode, the air conditioner enters the first demand response state or the second demand response state according to the preset condition satisfied by the set temperature; the set duration of the demand response state in the embodiment includes the first set duration in the step S13 and the second set duration in the step S23.

[0103] In some embodiments of the application, the control method further comprises: when the air conditioner is in the sleep mode and the air conditioner enters the demand response state, canceling the temperature change determination of the sleep mode.

[0104] In the embodiment, the temperature change determination is the temperature change determination in the sleep curve corresponding to the sleep mode. For example, the sleep mode of the air conditioner stipulates that, during the eight-hour sleep mode operation, the set target temperature T is divided into two-hour stages, and increases by 2℃ every stage, that is, T is assigned a value of T+2℃, and after reaching the set upper limit of temperature, the remaining time is operated at the set upper limit of temperature until the sleep mode is exited.

[0105] When the air conditioner is in the sleep mode and the air conditioner enters the demand response state, the temperature change determination of the sleep mode is canceled, avoiding the conflict between the demand response state and the temperature change determination of the sleep mode, thereby ensuring the effect of relieving power tension in the demand response state.

[0106] In some embodiments of the application, the reference Figure 4 , the control method further comprises the following steps:

[0107] Step S31: When the air conditioner is in the sleep mode and the set temperature satisfies the preset condition, the air conditioner enters the demand response state.

[0108] Step S32: Obtain the timing duration of the timing shutdown mode and the set duration of the demand response state.

[0109] Step S33: When the timing duration is less than the set duration, the air conditioner exits the demand response state when shutting down.

[0110] In the embodiment, when the air conditioner operating mode of the air conditioner is the timing shutdown mode, and the set temperature meets the first preset condition, the air conditioner enters the first demand response state; when the set temperature meets the second preset condition, the air conditioner enters the second demand response state. When the timing duration of the timing shutdown mode is less than the set duration of the demand response state, the air conditioner exits the demand response state when shutting down. The set duration of the demand response state in the embodiment includes the first set duration in the step S13 and the second set duration in the step S23.

[0111] In the timing shutdown mode state, when the air conditioner is restarted after shutting down at the timing time, the air conditioner does not continue to execute the demand response state. Instead, the air conditioner operates according to the mode after restarting.

[0112] In some embodiments of the application, if the demand response instruction is received when the air conditioner is executing the timing startup mode, the demand response instruction is ignored, and the response state is not entered. In the timing startup mode, the actual state of the air conditioner is shutdown, and the demand response does not need to be executed.

[0113] In some embodiments of the application, the control method further comprises:

[0114] After the air conditioner enters the demand response state, the air conditioner executes a prompt operation. And / or

[0115] After the air conditioner enters the demand response state, the air conditioner only responds to the shutdown instruction and the demand response cancellation instruction. And / or

[0116] After the air conditioner enters the demand response state, the air conditioner memorizes the current demand response state when shutting down, and continues to execute the demand response state after restarting.

[0117] In the embodiment, after the air conditioner enters the demand response state, the prompt operation of the air conditioner includes but is not limited to the display of a special identifier operation, voice prompt, LED flashing prompt, and the display of a special identifier operation includes the display on the smart screen and the display on the remote controller, which is determined by the actual function of the air conditioner to prompt the user that the air conditioner is currently in the demand response state.

[0118] After the air conditioner enters the demand response state, the air conditioner no longer accepts other normal instructions, unless the instruction is the shutdown instruction or the "cancel demand response" instruction issued by the upper computer; at the same time, the air conditioner that has entered the response state no longer accepts the new demand response instruction issued by the upper computer.

[0119] When the air conditioner enters the response state and has not reached the set time length, the user manually turns off the air conditioner, the air conditioner memorizes the current demand response state, and after restarting, the air conditioner still enters the demand response state until the set time length is reached to exit the demand response state.

[0120] After the default running time is reached, the demand response state is automatically exited; whether the demand response state is exited automatically or by the "cancel demand response" instruction issued by the upper computer, after the exit, if the air conditioner is turned off, the air conditioner remains turned off; if the air conditioner is turned on, the air conditioner is restored to the running state before entering the demand response state.

[0121] In some optional embodiments of the present application, the user can manually exit the demand response state, for example, a function button of the demand response state is added to the remote controller corresponding to the air conditioner, or a demand response state control switch is added to the APP end.

[0122] The user can manually select whether to enter the demand response state, instead of the air conditioner being forced to enter the demand response state after receiving the demand response instruction issued by the upper computer, and the user cannot control it.

[0123] In this embodiment, the user can manually select whether to enter the demand response state to adjust the running state of the air conditioner, thereby improving the user experience.

[0124] In some embodiments of the present application, for the air conditioner with an electricity accumulation function, the demand response state of the present application includes stopping the compressor and the outdoor fan for a period of time, restarting and running the compressor and the outdoor fan for a period of time, and repeating the above stopping and running processes of the compressor and the outdoor fan. The electricity accumulation function refers to that the air conditioner can detect the current running power in real time, and calculate the electricity of the air conditioner through the running power.
