and step S30, controlling the air conditioner to operate according to the target limiting frequency, wherein the target limiting frequency is the maximum operating frequency of the air conditioner in the current frequency limiting stage.
In this embodiment, the air conditioner may be provided with an energy saving mode. The air conditioner can receive a control instruction sent by the control terminal, and when the air conditioner receives the control instruction entering the energy receiving mode, the air conditioner can be controlled to enter the energy saving mode.
Optionally, after receiving a control instruction for entering an energy saving mode, the air conditioner may further obtain a control parameter set by the user, and when the control parameter meets the energy saving mode entry condition, the air conditioner is controlled to enter the energy saving mode. Otherwise, outputting prompt information that the set control parameters are unreasonable to prompt the user to modify the set control parameters. Wherein the control parameters may include a set temperature and an operation mode. The saving mode entering condition may include that the set temperature is greater than a preset temperature (e.g., 24 degrees) and/or that the operation mode is a cooling mode.
After the air conditioner enters the energy-saving mode, the indoor environment temperature in the air conditioner acting space can be obtained, and when the difference value between the indoor environment temperature and the set temperature is larger than a preset value (the preset value can be set to [4-8], for example, can be set to 5), the air conditioner firstly carries out a pre-cooling mode. In the cooling mode, the air conditioner may limit the maximum cooling power according to the energy saving mode, so that the difference between the indoor ambient temperature and the set temperature is less than or equal to a preset value. And the maximum refrigerating power corresponding to the energy-saving mode is a preset numerical value. The air conditioner can be set by self-definition according to the type, the refrigerating power and the like of the air conditioner.
Further, when the difference between the indoor environment temperature and the set temperature is smaller than or equal to a preset value, the air conditioner is sequentially controlled to enter each frequency limiting stage, wherein the frequency of each frequency limiting stage is sequentially reduced according to an execution sequence.
And then acquiring outdoor temperature, determining a frequency modulation coefficient of each frequency limiting stage according to the outdoor temperature, determining a target limiting frequency of each frequency limiting stage according to the frequency modulation coefficient of each frequency limiting stage and the limiting frequency corresponding to each stage, and limiting the frequency of the air conditioner according to the target limiting frequency corresponding to each frequency limiting stage, so that the air conditioner can control the operating frequency in advance before the ambient temperature reaches the set temperature and ensure the comfort of the air conditioner.
It should be noted that the target limiting frequency is used to limit the maximum value of the operating frequency of the air conditioner in the daily frequency limiting phase. The frequency limiting stage can be set to be multiple. The number of the frequency limiting stages can be set by a manufacturer in a customized manner, and the embodiment is not limited herein. To better understand the present invention, this example provides an alternative embodiment in which the air conditioner includes four frequency limiting stages. The present invention is explained below based on an air conditioner including four frequency-limited stages.
For example, when the air conditioner enters the energy saving mode, it may be determined whether a condition for entering a frequency limiting stage is currently met, where the condition for entering the frequency limiting stage is that a difference between an indoor temperature and a set temperature is smaller than or equal to the preset difference.
If yes, entering each frequency limiting stage in sequence, otherwise, executing the precooling stage, and entering the frequency limiting stage after the precooling stage is finished. When the difference value between the indoor temperature and the set temperature is smaller than or equal to the preset difference value, the precooling stage is ended; or the operation time of the precooling stage is longer than the preset time, and the precooling stage is ended.
After the air conditioner enters the first frequency limiting stage, the limiting frequency corresponding to the first frequency limiting stage and the outdoor environment temperature can be obtained. And then determining a temperature interval where the outdoor environment temperature is located, and acquiring a frequency modulation coefficient associated with the temperature interval. The larger the temperature value corresponding to the temperature interval is, the larger the frequency modulation coefficient is. For example, the temperature range may be set to three ranges of (-infinity, 35 ℃), [35 ℃,43 ℃ ], (43 ℃,) and the like, and the frequency modulation coefficient associated with the range of (-infinity, 35 ℃) is 1; the frequency modulation coefficient related to the interval of [35 ℃,43 ℃) is 1.3; the frequency modulation factor associated with the (43 ℃ C., ∞) interval is 1.5.
It is understood that the outdoor temperature may be obtained according to a temperature sensor disposed outdoors, and the temperature sensor may be connected with the air conditioner in a wired and/or wireless manner. The current weather parameters can be acquired through the server by communicating with the server, so that the current outdoor temperature can be determined according to the weather parameters.
When the frequency modulation coefficient is obtained, a target limit frequency may be determined according to the frequency modulation coefficient and a limit frequency associated with a current limit frequency interval, where the target frequency may be calculated according to the following formula:
M=Xs
wherein, M is the target frequency, X is the limiting frequency corresponding to the current limiting frequency stage, and s is the frequency modulation coefficient.
After the target frequency corresponding to the current frequency limiting stage is determined, the air conditioner can be controlled to operate according to the target frequency corresponding to the current frequency limiting stage.
Specifically, when the target frequency corresponding to the current frequency limiting stage is determined, the actual operating frequency of the air conditioner is obtained in the current frequency limiting stage, and when the actual operating frequency of the current operating stage is greater than the target limiting frequency, the air conditioner is controlled to adjust the operating frequency to the target limiting frequency. And when the target limit frequency is greater than the actual operating frequency, controlling the air conditioner to operate according to the actual operating frequency.
It can be understood that, when the air conditioner is provided with 4 frequency limiting stages, if the air conditioner operates in the energy saving mode, it is first determined whether the current indoor environment temperature meets the condition of entering the frequency limiting stage. And when the indoor temperature meets the condition of entering the frequency limiting stage, controlling the air conditioner to sequentially enter a first frequency limiting stage, a second frequency limiting stage, a third frequency limiting stage and a fourth frequency limiting stage. And when the indoor temperature does not meet the condition of entering the frequency limiting stage, controlling the air conditioner to enter a precooling stage, and when the precooling stage exits, controlling the air conditioner to enter the first frequency limiting stage, the second frequency limiting stage, the third frequency limiting stage and the fourth frequency limiting stage in sequence.
It should be noted that, after the air conditioner enters the frequency limiting stage, the operating duration, the indoor ambient temperature and the set temperature corresponding to the current frequency limiting stage may be obtained, then, a difference between the indoor ambient temperature and the set temperature is determined, and when the difference is less than or equal to a preset difference corresponding to the current frequency limiting stage, or the operating duration is greater than a preset duration corresponding to the current frequency limiting stage, the next frequency limiting stage is entered.
In the technical scheme disclosed in the implementation, when the air conditioner operates in an energy-saving mode, the air conditioner is sequentially controlled to enter each frequency limiting stage, the frequency limiting stages sequentially reduce the limiting frequency according to an execution sequence, a target limiting frequency is determined according to the outdoor ambient temperature and the limiting frequency of the current frequency limiting stage in each frequency limiting stage, the air conditioner is controlled to operate according to the target limiting frequency, so that the operating frequency of the current frequency limiting stage is smaller than or equal to the target limiting frequency, and the energy-saving mode is exited after all the frequency limiting stages are operated. The target limit frequency can be adjusted according to the outdoor environment temperature, so that the effect of improving the comfort of the air conditioner while reducing the energy consumption of the air conditioner is achieved.
Referring to fig. 3, based on the above embodiment, in another embodiment, the step S20 includes:
step S21, determining a target limiting frequency according to the outdoor environment temperature, the limiting frequency indoor temperature and the outdoor temperature of the current frequency limiting stage at each frequency limiting stage;
and step S22, controlling the air conditioner to operate according to the target limit frequency, so that the operating frequency of the current frequency limiting stage is less than or equal to the target limit frequency.
In this embodiment, after the air conditioner enters the current frequency limiting stage, the target limiting frequency corresponding to the current frequency limiting stage may be determined according to the outdoor environment temperature and the limiting frequency associated with the current frequency limiting stage. The difference between the indoor environment temperature and the set temperature can be obtained first, and when the difference is greater than or equal to a preset difference, the target limiting frequency corresponding to the last frequency limiting stage is used as the target limiting frequency corresponding to the current frequency limiting stage, that is, the operating frequency of the air conditioner in the current frequency limiting stage is controlled through the target limiting frequency corresponding to the last frequency limiting stage. And when the difference is smaller than the preset difference, controlling the operating frequency of the air conditioner in the current frequency limiting stage through the target limiting frequency corresponding to the current frequency limiting stage.
Illustratively, the preset difference value is a fixed numerical value set by a user. For example, it may be set to 2. According to the limiting frequency and the outdoor temperature corresponding to the current frequency limiting stage, the first target limiting frequency corresponding to the current frequency limiting stage can be determined. And acquiring a second target limiting frequency corresponding to the last frequency limiting stage. And when the difference is more than or equal to 2, limiting the air conditioner operation parameters in the current frequency limiting stage through the second target limiting frequency. And when the difference is less than 2, limiting the air conditioner operation parameters in the current frequency limiting stage through the first target limiting frequency.
In the technical solution disclosed in this embodiment, a target limit frequency for limiting the operating frequency of the air conditioner at the current frequency limit stage may be determined according to the outdoor environment temperature and the indoor environment, so as to further achieve the effect of improving the comfort of the air conditioner.
Based on the foregoing embodiment, in another embodiment, after the step S10, the method further includes:
acquiring the running time length and the time length interval of the energy-saving mode;
determining the operating wind speed and the angle of an air deflector of the air conditioner according to the operating duration and the duration interval of the energy-saving mode, wherein the larger the operating duration of the energy-saving mode is, the smaller the operating wind speed is;
and controlling the air conditioner to operate according to the operating wind speed and the angle of the air deflector.
In this embodiment, after the air conditioner enters the energy saving mode, the running time of the air conditioner running in the energy saving mode can be obtained in real time, and then the angle of the air deflector and the running wind speed of the air conditioner are determined according to the running time.
Specifically, a time interval corresponding to the operated time may be determined, and each time interval is associated with a corresponding operating wind speed and an angle of the air deflector. And further acquiring the associated wind guide angle and the operating wind speed according to the time interval of the operating time corresponding to the current time. And controlling the air conditioner according to the acquired air guide angle and the operating air speed.
Illustratively, the operation time period may be divided into three time period intervals of (0min, 30min), [30min,60min ], and (60min, ∞). And the three intervals of (0min, 30min), [30min,60min ] and (60min, ∞) are respectively associated with a first operation wind speed, a second operation wind speed and a third operation wind speed. Wherein the first operating wind speed may be calculated according to the following formula:
D1=dq
wherein D is1For a first operating wind speed, d is a set wind speed for the current wind speed, q is a wind adjustment parameter, wherein the wind adjustment parameter is greater than 1 constant, which may be set to 1.2, for example. Alternatively, the first operating wind speed D1It can also be calculated according to the following formula:
D1=d+p
d is the current wind speed set wind speed, and q is the wind speed increment.
Thus, when the running time is (0min, 30min), the wind speed running parameter can be determined according to the current set wind speed and the formula.
Second operating wind speed D2Can be calculated according to the following formula:
where d is the current wind speed set wind speed, c is a fixed constant, T is the elapsed time period, T1 is the start value of the current time period (30 in this example), and T2 is the end value of the current time period (60 in this example).
The third operating wind speed may be set to a fixed constant.
It should be noted that the greater the running time of the energy saving mode, the smaller the running wind speed. The duration interval can be associated with a fixed air deflector angle to achieve the effect of avoiding people from wind.
In the technical scheme disclosed in this embodiment, the running duration and the duration interval of the energy-saving mode are obtained; determining the operating wind speed and the angle of an air deflector of the air conditioner according to the operating duration and the duration interval of the energy-saving mode, wherein the larger the operating duration of the energy-saving mode is, the smaller the operating wind speed is; and controlling the air conditioner to operate according to the operating wind speed and the angle of the air deflector, so that the effect of improving the comfort of the air conditioner is achieved while the energy consumption of the air conditioner is reduced.
