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.
Further, after the air conditioner enters the energy-saving mode, the indoor environment temperature in the air conditioner acting space can be acquired, and when the difference value 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 limiting stages limit the frequency sequentially according to the execution sequence. Therefore, the air conditioner can carry out operation frequency control in advance before the ambient temperature reaches the set temperature.
it should be noted that, the frequency limiting stage means that the operating frequency of the air conditioner can be limited not to exceed the limiting frequency corresponding to the current frequency limiting stage in different frequency limiting stages. 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 this embodiment is not limited thereto. 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 will be explained based on an air conditioner including four frequency limiting stages.
For example, when the air conditioner enters the energy saving mode, the air conditioner may be controlled to enter a first frequency limiting phase. After the air conditioner enters the first frequency limiting stage, a first limiting frequency corresponding to the first frequency limiting stage can be acquired. And monitoring the current operating frequency of the air conditioner in real time. When the air conditioner operates in the first frequency limiting stage, whether the current operating frequency is greater than a first limiting frequency or not is judged, and when the current operating frequency is greater than the first limiting frequency, the air conditioner is controlled to adjust the operating frequency to the first limiting frequency and operate at the first limiting frequency.
the air conditioner can further obtain a first operation time length of the air conditioner in the first frequency limiting stage, and a difference value between the indoor environment temperature and the set temperature. When the first operation time length is greater than or equal to the first time length associated with the first frequency limiting stage, the air conditioner can be controlled to enter a second frequency limiting stage. Or, when the difference is smaller than a preset difference associated with the first stage, the air conditioner may be controlled to enter the second frequency limiting stage.
after the air conditioner enters the second frequency limiting stage, the operating frequency of the air conditioner can be controlled according to a second limiting frequency corresponding to the second frequency limiting stage. And controlling the air conditioner to exit the second frequency limiting stage and enter a third frequency limiting stage when detecting that the exit condition of the second frequency limiting stage is met. The exit condition of the second frequency limiting stage comprises that a second operation time length of the air conditioner in the second frequency limiting stage is greater than or equal to a second time length associated with the second frequency limiting stage, or the difference is less than or equal to a preset difference associated with the second frequency limiting stage.
After the air conditioner enters the third frequency limiting stage, the operating frequency of the air conditioner is controlled according to the third limiting frequency corresponding to the third frequency limiting stage, and when the exit condition of the third frequency limiting stage is met, the air conditioner exits the third frequency limiting stage and enters the fourth frequency limiting stage.
the exit condition of the third frequency limiting stage includes that a third operating time length of the air conditioner operating in the third frequency limiting stage is greater than or equal to a third time length associated with the third frequency limiting stage, or the difference is less than or equal to a preset difference associated with the third frequency limiting stage.
and when the air conditioner enters a fourth frequency limiting stage, controlling the operating frequency of the air conditioner according to a fourth limiting frequency corresponding to the fourth frequency limiting stage. And when the energy-saving mode exit condition is met, exiting the energy-saving mode. The exit condition of exiting the energy saving mode may be that an accumulated operating time of the air conditioner in the energy saving mode is longer than a preset accumulated time (for example, 10 h).
Optionally, the energy-saving mode can be exited when a mode switching instruction is received, an energy-saving mode exiting instruction is received, and/or a fault of an air conditioner component is detected.
it should be noted that the values of the preset difference values associated with the first frequency limiting stage, the second frequency limiting stage and the third frequency limiting stage are sequentially decreased. The first duration, the second duration and the third duration associated with the first frequency limiting stage, the second frequency limiting stage and the third frequency limiting stage may be set to the same value or may be set to different values, which is not limited in the embodiments.
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 limit the frequency sequentially according to an execution sequence, the air conditioner is controlled to operate according to the limiting frequency of the current frequency limiting stage under each frequency limiting stage, so that the operating frequency of the current frequency limiting stage is smaller than or equal to the limiting frequency of the current frequency limiting stage, and the energy-saving mode is exited after all the frequency limiting stages are operated. Thus, the effects of reducing the energy consumption of the air conditioner and saving energy are achieved.
referring to fig. 3, based on the foregoing embodiment, in another embodiment, before the step S20, the method further includes:
Step S40, acquiring indoor temperature at regular time;
step S50, the indoor temperature does not meet the frequency reduction condition, and the first frequency associated with the current frequency limiting stage is obtained as the limiting frequency; and the indoor temperature meets the frequency reduction condition, and the limiting frequency is determined according to the current operating frequency of the air conditioner and the preset frequency modulation parameter.
In this embodiment, before entering each frequency limiting stage, the air conditioner may determine a limiting frequency corresponding to the frequency limiting stage.
As an implementation scheme, each of the frequency limiting stages may associate a fixed frequency as a limiting frequency corresponding to the frequency limiting stage. Therefore, before entering each frequency limiting stage, the preset frequency associated with the frequency limiting stage may be obtained as the limiting frequency, and the operating frequency of the air conditioner may be controlled according to the limiting frequency in the frequency limiting stage.
as another implementation scheme, when the air conditioner enters a frequency limiting stage, a preset frequency associated with the frequency limiting stage may be acquired as the limiting frequency. And then acquiring the indoor temperature in the frequency limiting stage, and judging whether the indoor temperature meets the frequency reduction condition. And when the indoor temperature meets the frequency reduction condition, determining the limit frequency according to the current operating frequency of the air conditioner and a preset frequency modulation parameter. The frequency reduction condition can be set to be that the indoor temperature is in a descending trend, and the difference value between the indoor temperature and the set temperature is smaller than the frequency reduction difference value associated with the current frequency reduction stage.
specifically, when the air conditioner enters a frequency limiting stage, a first frequency associated with the frequency limiting stage may be acquired as the limiting frequency. And then the air conditioner operates for a detection time period in the current frequency limiting stage, and then the indoor temperature in the detection time period is obtained. And judging whether the indoor temperature is in a descending trend within the detection duration according to the indoor temperature within the detection duration. And when the indoor temperature is in a descending trend in the detection time length, acquiring a difference value between the indoor temperature and the set temperature at the end of the detection time length. And if the indoor temperature does not trend downwards in the detection duration, continuing to use the first frequency as the limiting frequency.
And when the indoor temperature is in a descending trend in the detection time length and the difference value is obtained, judging whether the difference value is smaller than a frequency reduction difference value associated with the current frequency limiting stage. When the difference is smaller than the downconversion difference, the downconversion coefficient associated with the current limiting stage may be obtained. Wherein the downconversion coefficient is less than 1. And obtains the current operating frequency.
then, a target frequency is calculated according to the frequency reduction coefficient and the current operating frequency, and the target frequency can be calculated according to the following formula:
M=Ds
wherein D is the target frequency, D is the current operating frequency, and s is the frequency reduction coefficient.
And after the target frequency is obtained through calculation, acquiring a second frequency associated with the next frequency limiting stage. And comparing the magnitude relationship between the target frequency and the second frequency. If the target frequency is greater than or equal to the second frequency, the target frequency is used as the limiting frequency, and if the second frequency is greater than the target frequency, the second frequency is used as the limiting frequency of the current frequency limiting stage.
it should be noted that the first frequency associated with the current frequency limiting stage is greater than the limiting frequency associated with the next frequency limiting stage. When the indoor temperature meets the frequency reduction condition, the refrigerating capacity of the air conditioner is larger than the environmental temperature returning capacity, so that the limiting frequency of the current frequency limiting stage can be reduced, the maximum value of the working frequency of the air conditioner is further limited, and the energy consumption of the air conditioner is limited.
In this embodiment, an indoor temperature is obtained, and when the indoor temperature does not satisfy a frequency reduction condition, a first frequency associated with the current frequency limiting stage is obtained as the limiting frequency; when the indoor temperature meets the frequency reduction condition, the limiting frequency is determined according to the current operating frequency of the air conditioner and the preset frequency modulation parameter, so that the energy consumption of the air conditioner can be further limited, the phenomenon of supercooling of the air conditioner is avoided, and the effect of saving energy is achieved.
based on the foregoing embodiment, in another embodiment, after the step S10, the method further includes:
acquiring a wind speed mode of the air conditioner, wherein the wind speed mode comprises an automatic mode and a set mode; the wind speed mode is an automatic mode, the running wind speed of the air conditioner is determined according to the preset wind speed associated with the current frequency limiting stage, and the air conditioner is controlled to run at the running wind speed; the wind speed mode is a set mode, and the air conditioner is controlled to operate at a preset set wind speed.
In this embodiment, when the air conditioner enters the energy saving mode, the frequency limiting stage where the air conditioner is located and the current wind speed mode of the air conditioner may be determined first. The wind speed mode comprises an automatic mode and a setting mode. The automatic mode refers to that a user sets the air conditioner to be capable of automatically adjusting the wind speed grade, and the setting mode refers to that the user sets the air conditioner to be at a fixed wind speed and the air conditioner cannot be adjusted by itself.
And when the wind speed mode is a set mode, controlling the air conditioner to operate at a preset set wind speed.
and when the wind speed mode is the automatic mode, judging whether the air conditioner operates in the last frequency limiting stage. And if so, controlling the air conditioner to operate at the preset wind speed. And if not, controlling the air conditioner to set the preset wind speed as a wind speed lower limit value. Even if the actual operating wind speed of the air conditioner is greater than or equal to the preset wind speed.
In the embodiment, a wind speed mode of the air conditioner is acquired, wherein the wind speed mode comprises an automatic mode and a setting mode; the wind speed mode is an automatic mode, the running wind speed of the air conditioner is determined according to the preset wind speed associated with the current frequency limiting stage, and the air conditioner is controlled to run at the running wind speed; the wind speed mode is a set mode, and the air conditioner is controlled to operate at a preset set wind speed. Thus, the purpose of ensuring the refrigeration effect of the air conditioner is achieved.
