Referring to fig. 1, an embodiment of the present disclosure provides a control method for an air conditioner, including the following steps:
s101, obtaining a first temperature difference value of the outdoor environment temperature and the indoor environment temperature.
The outdoor environment temperature is obtained through a network access weather forecast mode, the indoor environment temperature of the environment where the air conditioner is located and detected by the temperature sensor is obtained, and then a first temperature difference value between the outdoor environment temperature and the indoor environment temperature is obtained.
And S102, determining the target operation frequency of the air conditioner compressor corresponding to the first temperature difference value.
In the early test process, under the condition that different temperature differences exist between the outdoor environment temperature and the indoor environment temperature, the operation frequency of the compressor is determined by adjusting the operation frequency of the air-conditioning compressor when the indoor environment temperature can reach the target temperature at the fastest speed under the condition of different first temperature differences, the operation frequency is determined as the target operation frequency of the air-conditioning compressor corresponding to the current first temperature difference, and a first association relation table of the first temperature difference between the outdoor environment temperature and the indoor environment temperature and the target operation frequency of the compressor is established. And determining the target operation frequency of the air conditioner compressor corresponding to the first temperature difference value by searching the first association relation table based on the obtained first temperature difference value of the outdoor environment temperature and the indoor environment temperature.
And S103, controlling the compressor to operate according to the target operation frequency.
And after the target operation frequency is obtained, controlling the compressor to operate according to the target operation frequency, thereby realizing the indoor environment temperature regulation.
S104: and under the condition that the indoor environment temperature reaches the preset temperature, controlling the compressor to maintain the target operation frequency, and adjusting the rotating speed of a fan of the air conditioner so as to adjust the heat exchange quantity of the air conditioner.
The preset temperature is a target ambient temperature set by a user. Under the condition that the indoor environment temperature reaches the preset temperature, the compressor is controlled to maintain the running frequency without frequency release, the air conditioner heat exchange amount is adjusted by adjusting the rotating speed of the fan, the indoor environment temperature is further maintained stable, the compressor frequency does not need to be switched continuously to maintain the indoor environment temperature stable, and the generated noise is small.
Optionally, adjusting the rotation speed of the fan of the air conditioner to adjust the heat exchange amount of the air conditioner includes: obtaining the temperature change rate of the indoor environment temperature within a preset time period after the indoor environment temperature reaches a preset temperature; and adjusting the rotating speed of the fan according to the target operating frequency and the temperature change rate.
The preset time period may be a preset time period after the indoor ambient temperature reaches the preset temperature, for example, within three minutes after the indoor ambient temperature reaches the preset temperature. The target operation frequency of the compressor (i.e., the current operation frequency of the compressor) is related to the heating or cooling capacity of the air conditioner, and generally, the larger the target operation frequency of the compressor is, the larger the heating or cooling capacity of the air conditioner is, the stronger the capacity of changing the indoor ambient temperature is, whereas, the smaller the target operation frequency of the compressor is, the smaller the heating or cooling capacity of the air conditioner is, the weaker the capacity of changing the indoor ambient temperature is. The rotating speed of the fan is adjusted according to the target operating frequency of the compressor and the actual temperature change rate of the indoor environment temperature, so that the heat exchange quantity is adjusted, the indoor environment can be maintained more stably under the condition that the operating frequency of the compressor is not changed, and the user experience is improved.
Optionally, adjusting the rotation speed of the fan according to the target operating frequency and the temperature change rate includes: obtaining a rotating speed change value corresponding to the target operation frequency and the temperature change rate; and on the basis of the current rotating speed of the fan, reducing the rotating speed of the fan according to the rotating speed change value.
And pre-establishing a second incidence relation table of the target operation frequency and the temperature change rate and the rotating speed change value of the fan. In the second incidence relation table, the rotating speed change value of the fan is positively correlated with the target operating frequency and the temperature change rate of the compressor, namely, the larger the target operating frequency and the temperature change rate of the compressor are, the larger the rotating speed change value of the fan is; the smaller the target operation frequency and the temperature change rate of the compressor are, the smaller the change value of the rotating speed of the fan is. Based on the determined target operating frequency and the temperature change rate of the compressor, the rotating speed change value of the fan is determined by searching the second incidence relation table, the rotating speed of the fan is adjusted according to the rotating speed change value, the heat exchange quantity is adjusted, the stability of the indoor environment can be better maintained under the condition that the operating frequency of the compressor is not changed, meanwhile, the noise caused by continuous frequency conversion of the compressor can be avoided, and the user experience is improved.
By adopting the control method for the air conditioner provided by the embodiment of the disclosure, the target operation frequency corresponding to the first temperature difference value between the outdoor environment temperature and the indoor environment temperature is determined, the compressor of the air conditioner is controlled to operate according to the target operation frequency, the compressor is controlled to maintain the target operation frequency under the condition that the indoor environment temperature reaches the preset temperature, and the rotating speed of the fan of the air conditioner is adjusted to adjust the heat exchange capacity of the air conditioner. Like this, give an operating frequency of compressor according to current outdoor ambient temperature condition and indoor temperature condition to reach under the condition of predetermineeing the temperature at indoor ambient temperature, control compressor maintains this operating frequency, realize the regulation of air conditioner heat transfer volume through the rotational speed of adjusting the fan, and then maintain indoor ambient temperature's stability, need not to constantly switch compressor frequency and maintain indoor ambient temperature's stability, the noise of production is less, and user experience is better.
In some embodiments, the control method for an air conditioner further includes: detecting a first vibration frequency of a compressor and a second vibration frequency of a panel of an air conditioner; obtaining a vibration frequency difference value between the first vibration frequency and the second vibration frequency; and under the condition that the vibration frequency difference is smaller than or equal to the preset vibration frequency difference, controlling the compressor to operate at a reduced frequency on the basis of the target operation frequency.
The first vibration frequency of the compressor is used for representing the physical vibration speed of the compressor, and the second vibration frequency of the panel of the air conditioner is used for representing the physical vibration speed of the panel of the air conditioner. The preset vibration frequency difference value is the vibration frequency difference value of the first vibration frequency and the second vibration frequency measured when the panel is loosened in the early test process. When the panel is installed insecure, the air conditioner panel can generate resonance phenomenon along with the vibration of the compressor, and the noise generated by the panel vibration is larger than the noise generated when the compressor is operated at the switching frequency. Therefore, the installation condition of the air conditioner panel is known through the relation between the vibration frequency difference value of the first vibration frequency and the second vibration frequency and the preset vibration frequency difference value, when the vibration frequency difference value is smaller than or equal to the preset vibration frequency difference value, the fact that the air conditioner panel and the compressor have a resonance phenomenon is shown, the problem that the air conditioner panel is likely to be installed and loosened is solved, the compressor is controlled to operate at a target operation frequency, the frequency is reduced, noise generated by the air conditioner panel under strong vibration is avoided, and the risk that the air conditioner panel continuously vibrates at high frequency and falls is reduced.
Optionally, controlling the compressor to operate at a reduced frequency based on the target operating frequency comprises: obtaining a second temperature difference value between the indoor environment temperature and the preset temperature; determining a compressor frequency reduction value corresponding to the second temperature difference value; and controlling the compressor to operate at the reduced frequency value on the basis of the target operation frequency.
Here, the compressor step-down value is inversely related to the second temperature difference, i.e. the larger the second temperature difference, the smaller the compressor step-down value; the smaller the second temperature difference, the greater the compressor droop. When the compressor executes frequency reduction operation, a second temperature difference value between the indoor environment temperature and the preset temperature is obtained, the current refrigeration or heating condition of the air conditioner is known through the second temperature difference value, when the second temperature difference value is large, the indoor environment temperature is indicated to be far from the target temperature (preset temperature) required by a user, the frequency reduction value of the compressor is small, the compressor is controlled to operate at a certain frequency on the basis of the target operation frequency, when the second temperature difference value is small, the indoor environment temperature is indicated to be about to reach the target temperature (preset temperature) required by the user, the frequency reduction value of the compressor is large, the compressor is controlled to operate at a large frequency on the basis of the target operation frequency, the noise generated by the air conditioner panel under strong vibration is reduced, meanwhile, normal air conditioning of the air conditioner is guaranteed to the greatest extent, and the user experience is improved.
Optionally, the control method for an air conditioner further includes: sending out prompt information under the condition that the vibration frequency difference is smaller than or equal to a preset vibration frequency difference; wherein the prompt message is used for prompting the user of the panel installation fault.
When the vibration frequency difference is smaller than or equal to the preset vibration frequency difference, the resonance phenomenon of the air conditioner panel and the compressor is indicated, the air conditioner panel is likely to be installed and loosened, a user is timely reminded of processing, and the life and property safety of the user is guaranteed.
In some embodiments, the control method for an air conditioner further includes: obtaining a noise value generated by an indoor unit of an air conditioner; and controlling the opening angle of the microporous air deflector of the air conditioner according to the noise value.
When the sound wave passes through the microporous air deflector of the air conditioner, the sound wave is continuously reflected in the irregular microporous structure of the air deflector, and the intensity of the sound wave can be reduced. Therefore, the opening angle of the microporous air deflector can be controlled according to the noise value of the indoor unit of the air conditioner, the normal heating or refrigerating operation of the air conditioner is not influenced, the noise value generated in the air conditioner can be properly reduced, and the user experience is improved.
Optionally, the controlling the opening angle of the micro-porous air deflector of the air conditioner according to the noise value includes: controlling the micropore air deflector to be closed under the condition that the noise value is greater than or equal to a first preset noise value; and controlling the micropore air deflector to be opened to a preset angle under the condition that the noise value is greater than or equal to a second preset noise value and smaller than a first preset noise value.
The first preset noise value may be a relatively large noise value set by the user, and the noise value has a relatively large influence on the daily activities of the user; the second noise value may be a small noise value set by the user, which has a small influence on the daily activities of the user. When the noise value is greater than or equal to the first preset noise value, controlling the micropore air deflector to be closed in order to better reduce the noise of the indoor unit of the air conditioner; under the condition that the noise value is greater than or equal to the second preset noise value and smaller than the first preset noise value, the micropore air deflector is controlled to be opened to a preset angle (for example, the opening angle is 30 degrees), noise of the indoor unit of the air conditioner is reduced, and meanwhile the air output of the air conditioner can be better guaranteed (the air output of the micropores of the air conditioner is smaller than the air output of the air deflector of the air conditioner when the air deflector of the air conditioner is opened), so that heating or refrigerating operation of the air conditioner is better maintained, and user experience is improved.
