The present invention provides a method for controlling an operating frequency of an air conditioner, and fig. 2 is a flowchart of a first embodiment of the method for controlling an operating frequency of an air conditioner according to the present invention. In this embodiment, the operation frequency control method of the air conditioner includes the steps of:
step S10, acquiring the current ambient temperature;
the current ambient temperature is the current indoor ambient temperature. The current ambient temperature can be obtained in real time, or can be obtained at regular time or at preset time intervals, or can be triggered to be obtained when the change of the ambient temperature is detected, and the method is not limited.
The current ambient temperature may be obtained by detecting the indoor ambient temperature by an ambient temperature detecting device, such as a temperature sensor or a temperature sensing bulb, provided in the air conditioner, or may be obtained by indirectly detecting the indoor ambient temperature by a remote controller, or may be obtained by detecting the first ambient temperature obtained by the ambient temperature detecting device of the air conditioner, and determining the average value of the first ambient temperature and the second ambient temperature as the ambient temperature by detecting the second ambient temperature obtained by the indoor ambient temperature by the remote controller.
Step S20, determining a target operating frequency according to the environment temperature, wherein the target operating frequency is determined based on a history adjustment parameter corresponding to the environment temperature;
and step S30, controlling the compressor of the air conditioner to run according to the target running frequency.
The historical adjustment parameters comprise frequency adjustment parameters, the frequency adjustment parameters comprise up-adjustment times and down-adjustment times, wherein the up-adjustment times can be understood as times of up-adjustment performed by a user when the current environment temperature corresponds to the temperature value, and similarly, the down-adjustment times can be understood as times of down-adjustment performed by the user when the current environment temperature corresponds to the temperature value.
As an optional implementation manner, referring to fig. 3, fig. 3 is a flow chart illustrating a method for controlling an operating frequency of an air conditioner according to the present invention, in this embodiment, determining a target operating frequency according to an ambient temperature, step S20 includes:
step S21, acquiring historical adjustment parameters corresponding to the ambient temperature, wherein the historical adjustment parameters comprise frequency adjustment parameters;
and S22, acquiring a target operating frequency according to the history adjustment parameters.
It should be noted that in this embodiment, different environmental temperatures are all corresponding to historical adjustment parameters, which may also be understood that different environmental temperatures are all corresponding to frequency adjustment parameters, when an up-adjustment instruction or a down-adjustment instruction of a user is received at an environmental temperature, the stored up-adjustment times or down-adjustment times may be updated, and the environmental temperature, the down-adjustment times and the up-adjustment times are stored in an associated manner, that is, the association between the environmental temperature and the frequency adjustment parameters or the historical adjustment parameters is achieved, and optionally, the operation mode, the environmental temperature and the historical adjustment parameters are associated based on the operation mode in which the current environmental temperature is located. Based on the associated environmental temperature and the historical adjustment parameters, the historical adjustment parameters corresponding to the environmental temperature can be obtained, and in this embodiment, obtaining the historical adjustment parameters corresponding to the environmental temperature can be understood as obtaining the frequency adjustment parameters, i.e. the up-adjustment times and the down-adjustment times, in the historical adjustment parameters corresponding to the environmental temperature.
The method comprises the steps of obtaining historical adjustment parameters corresponding to the current environment temperature, wherein the historical adjustment parameters comprise frequency adjustment parameters, the frequency adjustment parameters in the environment temperature can be obtained through the historical adjustment parameters, the historical adjustment parameters are obtained through statistics based on adjustment operation performed by a user in the environment temperature, and the target operation frequency of the compressor of the air conditioner is obtained according to the historical adjustment parameters comprising the frequency adjustment parameters, namely, the operation frequency of the compressor of the air conditioner is determined based on the adjustment behavior habit of the user in the environment temperature, so that the purpose of adapting to the adjustment requirement of the user can be achieved.
As an alternative embodiment, step S21 includes:
acquiring a current operation mode;
and acquiring a history adjusting parameter corresponding to the ambient temperature in the operation mode.
The operating modes include, but are not limited to, a cooling mode and a heating mode. It is easy to understand that, corresponding to the operation modes including the cooling mode and the heating mode, after the air conditioner is turned on, since the purposes of the user's requirement for the adjustment of the ambient temperature are different, the historical adjustment parameters of the same ambient temperature in the cooling mode or the heating mode may be the same or different. Based on the associated operating mode, ambient temperature, and historical adjustment parameters, historical adjustment parameters corresponding to the ambient temperature in an operating mode, such as a heating mode or a cooling mode, may be obtained.
It should be noted that, the specific implementation of obtaining the target operating frequency according to the history adjusting parameter may be through presetting a corresponding relationship between the history adjusting parameter and the target operating frequency, where the corresponding relationship may be obtained by a calculation equation including the history adjusting parameter, or may be other manners; frequency adjustment parameters in the history adjustment parameters can also be obtained; wherein the frequency adjustment parameters comprise the number of up-adjustments and the number of down-adjustments; determining an adjustment coefficient according to the current operation mode and the frequency adjustment parameter; the target operating frequency is determined according to the adjustment coefficient, the maximum operating frequency and the minimum operating frequency of the compressor, which is not limited. And finally, controlling the compressor of the air conditioner to operate according to the target operating frequency.
As an optional implementation manner, step S20 may be performed by updating the target operating frequency according to the environmental temperature, that is, after updating the historical adjustment parameter corresponding to the environmental temperature, that is, detecting that the temperature value of the environmental temperature receives the up-adjustment instruction or the down-adjustment instruction, updating the up-adjustment frequency or the down-adjustment frequency corresponding to the environmental temperature, and obtaining the target operating frequency corresponding to the environmental temperature according to the updated historical adjustment parameter, so as to directly associate the environmental temperature with the target operating frequency, thereby realizing that the target operating frequency is directly determined according to the environmental temperature, and realizing simpler implementation.
In the technical scheme disclosed in this embodiment, the target operating frequency of the compressor of the air conditioner is determined according to the ambient temperature, and because the target operating frequency is determined based on the historical adjustment parameter corresponding to the ambient temperature, and the historical adjustment parameter is obtained by statistics based on the adjustment operation performed by the user at the ambient temperature, the target operating frequency of the compressor of the air conditioner is obtained according to the historical adjustment parameter including the frequency adjustment parameter, that is, the operating frequency of the compressor of the air conditioner is determined based on the adjustment behavior habit performed by the user at the ambient temperature, so as to achieve the purpose of adapting to the adjustment requirement of the user.
Referring to fig. 4, fig. 4 is a flowchart illustrating a second embodiment of the operation frequency control method of the air conditioner according to the present invention, which is based on the second embodiment of the operation frequency control method of the air conditioner according to the present invention. In this embodiment, step S21 is preceded by:
step S40, comparing the ambient temperature with a pre-stored expected temperature; wherein the expected temperature is a temperature corresponding to the preset difference between the up-regulation times and the down-regulation times of the frequency regulation parameters when the difference is the minimum;
step S50, when the operation mode is a refrigeration mode and the ambient temperature is greater than the expected temperature, executing step S21 to obtain the history adjustment parameters corresponding to the ambient temperature; or,
step S60, when the operation mode is the heating mode and the ambient temperature is less than or equal to the desired temperature, step S21 is also executed to obtain the historical adjustment parameter corresponding to the ambient temperature.
The expected temperature is the temperature corresponding to the time when the difference between the up-regulation times and the down-regulation times of the pre-stored frequency regulation parameters is the minimum. Alternatively, the desired temperature is a temperature at which the difference between the number of up-adjustments and the number of down-adjustments is zero, i.e., the up-adjustment probability and the down-adjustment probability are equal. The pre-stored frequency adjustment parameters comprise frequency adjustment parameters corresponding to different environmental temperatures respectively. In the actual application process, when the frequency adjustment parameter is at the first ambient temperature, when an up-adjustment instruction or a down-adjustment instruction of a user is received, the frequency adjustment parameter corresponding to the first ambient temperature may be updated, that is, the up-adjustment frequency or the down-adjustment frequency corresponding to the first ambient temperature is updated, where the first ambient temperature may be an ambient temperature associated with any one of the pre-stored frequency adjustment parameters. It can be understood that, because the user is in the up-regulation instruction or the down-regulation instruction of the first ambient temperature, the frequency regulation parameters corresponding to the different ambient temperatures respectively are in an updatable state, that is, the frequency regulation parameters corresponding to the different ambient temperatures respectively can be dynamically changed along with the adjustment operation performed by the user, such as the up-regulation instruction or the down-regulation instruction. As such, it is readily understood that the desired temperature is not the only one, and as such, the desired temperature may vary with the adjustment operation performed by the user.
In order to facilitate understanding of the present embodiment, the following description will be given by way of example of a change in the operating frequency of the compressor of the air conditioner when a desired temperature is changed in the cooling mode. For example: the outdoor temperature is 32 degrees, the indoor environment temperature is 30 degrees, the air conditioner A is started for refrigeration, the set temperature is 22 degrees, and the expected temperatures of users today/tomorrow/postnatal are respectively as follows: 24 °, 24.5 °, and 25 °. Where T1 is denoted as the indoor ambient temperature, the target operating frequency=minimum operating frequency+the adjustment coefficient (maximum operating frequency-minimum operating frequency), where the adjustment coefficient may be understood as the cooling probability.
Today:
t1>24.5 °, target operating frequency=minimum operating frequency+t1 corresponds to the adjustment coefficient (maximum operating frequency-minimum operating frequency);
t1< = 24.5 °, target operating frequency = lowest frequency;
tomorrow:
when T1>25.0 °, the target operating frequency=minimum operating frequency+t1 corresponds to the adjustment coefficient (maximum operating frequency-minimum operating frequency);
t1< = 25.0 °, target operating frequency = lowest operating frequency;
postamble:
when T1>25.5 °, the target operating frequency=minimum operating frequency+t1 corresponds to the adjustment coefficient (maximum operating frequency-minimum operating frequency);
at T1< = 25.5 °, the target operating frequency = lowest operating frequency.
In the actual application process, as the obtained operation data of the adjustment operation performed by the user increases in the number of up-adjustments and/or down-adjustments, the expected temperature is taken as the temperature corresponding to the time when the difference between the up-adjustments and the down-adjustments of the pre-stored frequency adjustment parameters is the minimum, that is, the up-adjustments and the down-adjustments corresponding to the expected temperature are relatively balanced. It should be noted that, in the refrigeration mode, when the current ambient temperature is greater than the expected temperature, the current ambient temperature can be simply understood as the number of times of down-regulation is greater than the number of times of up-regulation, that is, the probability of down-regulation is greater; when the current ambient temperature is smaller than the expected temperature, the current ambient temperature can be simply understood as the current ambient temperature is lower in the number of times of being adjusted down than the number of times of being adjusted up, namely the probability of being adjusted up is high. In the heating mode, when the current ambient temperature is smaller than the expected temperature, the current ambient temperature can be simply understood as the up-regulation times of the current ambient temperature is larger than the down-regulation times, namely the up-regulation probability is larger; when the current ambient temperature is greater than the expected temperature, the current ambient temperature can be simply understood as having a smaller number of times of up-regulation than the number of times of down-regulation, i.e. a larger probability of down-regulation. The up-regulation probability and/or down-regulation probability corresponding to the environmental temperature are determined according to the number of times of the adjustment operation, such as the up-regulation instruction or the down-regulation instruction, performed by the user at the environmental temperature, and the up-regulation probability and/or the down-regulation probability can be regarded as the adjustment requirement or the adjustment tendency of the user at the environmental temperature.
In addition, in different operation modes, no matter whether the ambient temperature is higher than the expected temperature or lower than or equal to the expected temperature, the absolute value corresponding to the difference value between the up-adjustment times and the down-adjustment times is in a gradually decreasing trend when the ambient temperature is closer to the expected temperature, the corresponding down-adjustment probability of the down-adjustment times is in a gradually decreasing trend when the ambient temperature is in a refrigeration mode, and the adjustment coefficient is in a gradually decreasing trend; in a heating mode, the corresponding up-regulation probability of the up-regulation times at the ambient temperature is gradually reduced, and the regulation coefficient is gradually reduced, so that when the ambient temperature is gradually close to the expected temperature, the operation frequency of the compressor of the air conditioner is gradually reduced, the compressor of the air conditioner gradually reduces the frequency until the minimum operation frequency is reached, the energy consumption is effectively reduced, and the operation frequency of the compressor can be dynamically regulated according to the ambient temperature.
In the practical application process, when the air conditioner just starts to operate, and the acquired operation data of the adjustment operation performed by the user are less, the acquired frequency adjustment parameters of the expected temperature and other environment temperatures except the expected temperature are not regular, and in order to avoid errors caused by the determined expected temperature, the historical adjustment parameters corresponding to the environment temperature can be acquired to control the compressor of the air conditioner to operate according to the target operation frequency acquired according to the historical adjustment parameters. Namely:
when the operation mode is a refrigeration mode and the ambient temperature is greater than the expected temperature, namely, the down-regulation probability is larger, the step S21 is executed, namely, the history regulation parameters corresponding to the ambient temperature are obtained; or,
when the operation mode is the heating mode and the ambient temperature is less than or equal to the expected temperature, that is, the up-regulation probability is high, the step S21 is executed, that is, the history regulation parameter corresponding to the ambient temperature is obtained.
Optionally, after step S40, the method includes:
when the operation mode is a refrigeration mode and the ambient temperature is less than or equal to the expected temperature, controlling a compressor of the air conditioner to operate according to the minimum operation frequency; or,
and when the operation mode is a heating mode and the ambient temperature is greater than the expected temperature, controlling the compressor of the air conditioner to operate according to the minimum operation frequency.
It should be noted that, in the refrigeration mode, when the ambient temperature is less than or equal to the desired temperature, that is, when the current ambient temperature with a higher up-regulation probability is supercooled, the compressor of the air conditioner can be controlled to operate according to the minimum operating frequency, so as to avoid discomfort to the user caused by further supercooling of the ambient temperature when the air conditioner is operated with the operating frequency greater than the minimum operating frequency. In the heating mode, when the ambient temperature is greater than the expected temperature, that is, when the current ambient temperature with a higher down-regulation probability is overheated, the compressor of the air conditioner can be controlled to operate according to the minimum operating frequency, so that discomfort of a user caused by the overheat of the ambient temperature when the air conditioner is operated with the operating frequency greater than the minimum operating frequency is avoided.
In the technical scheme disclosed in the embodiment, by comparing the ambient temperature with a pre-stored expected temperature, wherein the expected temperature is a temperature corresponding to the time when the difference between the up-adjustment times and the down-adjustment times of the pre-stored frequency adjustment parameters is the minimum, that is, the up-adjustment times and the down-adjustment times corresponding to the expected temperature are relatively balanced, the compressor operation modes of the air conditioner are controlled by directly comparing the ambient temperature with the expected temperature in different operation modes, for example, when the operation mode is a refrigeration mode and the ambient temperature is less than or equal to the expected temperature, the compressor of the air conditioner is controlled to operate according to the minimum operation frequency; or when the operation mode is a heating mode and the environmental temperature is greater than the expected temperature, controlling the compressor of the air conditioner to operate according to the minimum operation frequency, so that the adjustment of the operation frequency of the compressor of the air conditioner is more flexible.
Referring to fig. 5, fig. 5 is a flowchart illustrating a third embodiment of an operation frequency control method of an air conditioner according to the present invention. In this embodiment, step S22 includes:
step S221, obtaining the frequency adjustment parameters in the history adjustment parameters; wherein the frequency adjustment parameters comprise up-regulation times and down-regulation times;
step S222, determining an adjustment coefficient according to the current operation mode and the frequency adjustment parameter;
and step S223, determining the target operating frequency according to the adjusting coefficient, the maximum operating frequency and the minimum operating frequency of the compressor.
And acquiring frequency adjustment parameters in the historical adjustment parameters, namely acquiring the up-regulation times and the down-regulation times of the current ambient temperature. The adjustment coefficient is determined according to the current operation mode and the frequency adjustment parameter, and is substantially determined according to the current operation mode, the number of times of up-regulation and the number of times of down-regulation, and it should be noted that in different operation modes, the number of times of up-regulation and the number of times of down-regulation of the same environmental temperature are generally different, but when in different operation modes, the number of times of up-regulation and the number of times of down-regulation of the same environmental temperature are the same. In general, the different operating modes differ from each other in the adjustment coefficient determined by the same ambient temperature.
Optionally, referring to fig. 6, fig. 6 is a flow chart illustrating a method for controlling an operation frequency of an air conditioner according to the present invention, in which the determining of the adjustment coefficient in the cooling mode in the present embodiment, step S222 includes:
step S2221, when the operation mode is a cooling mode and the number of up-adjustments is greater than the number of down-adjustments, determining that the adjustment coefficient is a preset value;
step S2222, when the operation mode is a cooling mode and the number of up-adjustments is less than or equal to the number of down-adjustments, determining the adjustment coefficient according to a down-adjustment probability corresponding to the number of down-adjustments.
In the practical application process, in different operation modes, determining that the correlation between the adjustment coefficient of the ambient temperature and the up-adjustment times and down-adjustment times under the ambient temperature is large, if in a refrigeration mode, determining that the adjustment coefficient of the ambient temperature can be obtained by determining the up-adjustment times and down-adjustment times under the ambient temperature according to the up-adjustment times and the down-adjustment times, further determining the up-adjustment probability and the down-adjustment probability corresponding to the ambient temperature according to the up-adjustment times and the down-adjustment times, and when the down-adjustment probability is larger than the up-adjustment probability, indicating that the ambient temperature does not reach the refrigeration requirement required by a user, obtaining the adjustment coefficient corresponding to the preset probability interval through the preset probability interval where the down-adjustment probability is located, for example, determining that the adjustment coefficient is 0 when the down-adjustment probability is smaller than or equal to 0.5 and the down-adjustment probability is larger than 0; when the down-regulation probability is greater than 0.5 and the down-regulation probability is less than 1, determining that the regulation coefficient is greater than 0 and less than or equal to 1, wherein the down-regulation probability can be further set in multiple probability intervals, setting corresponding regulation coefficients for all probability intervals, determining that the regulation coefficient is 0.6 when the down-regulation probability is greater than 0.5 and less than 0.7, and determining that the regulation coefficient is 0.8 when the down-regulation probability is greater than or equal to 0.7 and less than 1.
It will be appreciated that when the mode of operation is a cooling mode and the number of turnups is greater than the number of turndowns, indicating that the ambient temperature is perceived by the user as overcooled, the adjustment factor may be determined to be a preset value, optionally zero.
Optionally, referring to fig. 7, fig. 7 is a flowchart illustrating a method for controlling an operation frequency of an air conditioner according to the present invention, in which the step S222 includes:
step S2223, when the operation mode is a heating mode and the number of times of up-regulation is greater than or equal to the number of times of down-regulation, determining the adjustment coefficient according to the up-regulation probability corresponding to the number of times of up-regulation;
step S2224 is to determine that the adjustment coefficient is a preset value when the operation mode is a heating mode and the up-adjustment number is smaller than the down-adjustment number.
Similarly, in the heating mode, the adjustment coefficient of the ambient temperature can be determined by acquiring the up-adjustment times and the down-adjustment times when the ambient temperature is up-adjusted, the up-adjustment probability and the down-adjustment probability corresponding to the ambient temperature are further determined according to the up-adjustment times and the down-adjustment times, the up-adjustment probability is larger than the up-adjustment probability, and when the ambient temperature does not reach the heating requirement required by a user, the adjustment coefficient corresponding to the preset probability interval can be acquired through the preset probability interval where the up-adjustment probability is located.
It will be appreciated that when the operating mode is a heating mode and the number of turnups is less than the number of turndowns, indicating that the ambient temperature is causing the user to feel excessive heat, the adjustment factor may be determined to be a preset value, optionally zero.
Determining a target operating frequency according to the adjustment coefficient, the maximum operating frequency of the compressor and the minimum operating frequency, wherein the relationship between the target operating frequency and the adjustment coefficient, the maximum operating frequency of the compressor and the minimum operating frequency can be defined through calculation, for example, the target operating frequency=minimum operating frequency+adjustment requirement coefficient (maximum operating frequency-minimum operating frequency), and it is noted that the adjustment requirement coefficient can be the adjustment coefficient; the expression may be a algebraic expression including the adjustment coefficient, and is not limited thereto. Optionally, the adjustment demand coefficient is an adjustment coefficient, and when the operation mode is a refrigeration mode and the number of up-adjustments is greater than the number of down-adjustments, the preset value of the adjustment coefficient is determined to be zero, so that the compressor of the air conditioner operates according to the minimum operation frequency; or when the operation mode is a heating mode and the up-regulation times are smaller than the down-regulation times, determining that the preset value of the regulation coefficient is zero so that the compressor of the air conditioner operates according to the minimum operation frequency.
In addition, the target operating frequency may be determined according to the adjustment coefficient, the maximum operating frequency and the minimum operating frequency of the compressor, or the target operating frequency may be determined directly by the adjustment coefficient, the corresponding relationship between the adjustment coefficient interval and the operating frequency may be set on the basis of determining the operating frequency based on the adjustment coefficient, the maximum operating frequency and the minimum operating frequency of the compressor, and after the adjustment coefficient is obtained, the operating frequency corresponding to the adjustment coefficient interval is determined as the target operating frequency by obtaining the adjustment coefficient interval in which the adjustment coefficient is located.
In the technical scheme disclosed in the embodiment, the historical adjustment parameters corresponding to the current environment temperature are obtained to obtain the frequency adjustment parameters, namely the up-adjustment times and the down-adjustment times of the user at the environment temperature, and the adjustment coefficients of the target operation frequency of the compressor are determined and obtained based on the current operation mode by the adjustment frequency parameters of the user, namely the up-adjustment and the down-adjustment can be performed according to the adjustment operation of the user at the environment temperature, so that the operation frequency of the compressor is dynamically adjusted, and the purpose of self-adapting to the user requirement is achieved.
Referring to fig. 8, fig. 8 is a flowchart illustrating a fourth embodiment of an operation frequency control method of an air conditioner according to the present invention. In this embodiment, step S10 is followed by:
step S70, detecting whether the ambient temperature changes;
step S80, when the ambient temperature changes, step S20 is performed, that is, the target operating frequency is determined according to the ambient temperature.
Whether the ambient temperature changes or not is detected, the ambient temperature can be detected in real time through the ambient temperature detection device, and the ambient temperature can also be detected through the ambient temperature detection device at preset time intervals, so that the method is not limited. Detecting whether the environmental temperature changes or not can be achieved by comparing the environmental temperatures detected twice continuously, and when the two detected environmental temperatures are unequal, the environmental temperature can be judged to change; the environmental temperature detected twice continuously can be obtained, the difference value between the two environmental temperatures is obtained, and when the difference value is not zero, the change of the environmental temperature can be judged. When the ambient temperature changes, step S20 is performed to determine the target operating frequency according to the ambient temperature.
In order to facilitate understanding of the present embodiment, the following description will exemplify the change in the operating frequency of the compressor of the air conditioner when the change in the ambient temperature is detected in the cooling mode. The outdoor temperature is 32 degrees, the indoor environment temperature is 30 degrees, the air conditioner is started for refrigeration, the set temperature is 22 degrees, and the expected temperature of a user is 25 degrees. The expected temperature is a temperature corresponding to the preset frequency adjustment parameter when the difference between the up-adjustment frequency and the down-adjustment frequency is the minimum, and the up-adjustment frequency or the down-adjustment frequency is positively related to an adjustment operation of a user at an ambient temperature, such as an up-adjustment instruction or a down-adjustment instruction.
When the high-frequency refrigeration operation is started and the change of the ambient temperature is detected, if the indoor temperature is reduced by 1 degree, the current adjusting coefficient of the ambient temperature is determined through the frequency adjusting parameter, and the adjusting coefficient can be understood as the cooling probability so as to control the compressor to run in a cooling mode until the lowest running frequency is reached. Where target operating frequency = lowest operating frequency + adjustment factor (highest operating frequency-lowest operating frequency), for example:
when the indoor environment temperature is 29 °, the target operating frequency=minimum operating frequency+0.95 (maximum operating frequency-minimum operating frequency);
when the indoor environment temperature is 28 °, the target operating frequency=minimum operating frequency+0.85 (maximum operating frequency-minimum operating frequency);
when the indoor environment temperature is 27 °, the target operating frequency=minimum operating frequency+0.60 (maximum operating frequency-minimum operating frequency);
when the indoor environment temperature is 26 °, the target operating frequency=minimum operating frequency+0.25 (maximum operating frequency-minimum operating frequency);
when the indoor ambient temperature is less than or equal to 25 °, the target operating frequency=the lowest operating frequency.
It should be noted that, in the application scenario in the cooling mode, when the operation data of the adjustment operation performed by a large number of users is obtained, such as the up-adjustment frequency and/or the down-adjustment frequency, the desired temperature is taken as the temperature corresponding to the time when the difference between the up-adjustment frequency and the down-adjustment frequency in the pre-stored frequency adjustment parameters is the minimum, that is, the up-adjustment frequency and the down-adjustment frequency corresponding to the desired temperature are at the relatively balanced position. The absolute value corresponding to the difference between the up-regulation times and the down-regulation times is gradually reduced when the ambient temperature is closer to the expected temperature, the corresponding down-regulation probability of the down-regulation times at the ambient temperature is gradually reduced, and the regulating coefficient is gradually reduced, so that the operating frequency of the compressor of the air conditioner is gradually reduced when the ambient temperature is gradually close to the expected temperature, and the compressor of the air conditioner gradually reduces the frequency until the lowest operating frequency is reached.
In the technical scheme disclosed in the embodiment, as long as the temperature is detected to change, the corresponding historical adjustment parameters of the changed environmental temperature are determined based on the changed environmental temperature, and the adjustment coefficient of the target operating frequency of the compressor is determined and obtained according to the adjustment frequency parameters of the user, namely the frequency adjustment parameters, of the historical adjustment parameters, and the adjustment operation performed by the user at the environmental temperature is adjusted up and down according to the adjustment operation performed by the user, so that the dynamic adjustment of the operating frequency of the compressor is realized, and the purpose of self-adapting to the user requirement is achieved.
