In an embodiment of the present application, referring to fig. 1, a control device of an air conditioner includes: a processor 1001 (e.g., CPU), a memory 1002, a timer 1003, and the like. The components in the control device are connected through a communication bus. The memory 1002 may be a high-speed RAM memory or a stable memory (non-volatile memory), such as a disk memory. The memory 1002 may alternatively be a storage device separate from the processor 1001 described above.
It will be appreciated by those skilled in the art that the device structure shown in fig. 1 is not limiting of the device and may include more or fewer components than shown, or may be combined with certain components, or a different arrangement of components.
As shown in fig. 1, a control program of an air conditioner may be included in a memory 1002 as one type of storage medium. In the apparatus shown in fig. 1, a processor 1001 may be used to call a control program of an air conditioner stored in a memory 1002 and perform the relevant step operations of the control method of the air conditioner of the following embodiment.
The embodiment of the application also provides a control method of the air conditioner, which is applied to the air conditioner.
Referring to fig. 2, an embodiment of a control method of an air conditioner according to the present application is provided. In this embodiment, the control method of the air conditioner includes:
step S10, receiving a starting instruction of a compressor of an air conditioner, and acquiring indoor environment temperature and outdoor environment temperature;
the starting instruction can be generated according to the instruction input by the user, and can also be generated according to the actual scene condition of the indoor environment monitored by the air conditioner. For example, the start-up command may be generated when the indoor unit of the air conditioner receives a start-up command, and for example, the start-up command may be generated when the air conditioner detects that the indoor environment temperature deviates from a preset comfort temperature interval.
In this embodiment, after receiving a start instruction of the compressor, the compressor may be controlled to maintain a closed state and acquire an indoor environment temperature and an outdoor environment temperature. In other embodiments, the compressor can be controlled to raise the frequency at a rate smaller than the set rate, and the indoor environment temperature and the outdoor environment temperature are obtained in the raising process; the compressor may also be controlled to operate at an initial frequency (e.g., a preset minimum frequency, etc., mentioned later) that is less than the set frequency, and the indoor ambient temperature and the outdoor ambient temperature are obtained when the compressor operates at the initial frequency.
In this embodiment, the data detected in real time by the ambient temperature detection module is acquired as the indoor ambient temperature and the outdoor ambient temperature. In other embodiments, the indoor environment temperature and the outdoor environment temperature may be determined by acquiring a plurality of data detected by the environment temperature detection module within a preset time period after receiving the start command of the compressor.
Step S20, determining a first temperature difference value between the indoor environment temperature and a set temperature;
the set temperature is a target value which is required to be reached by presetting the temperature of the indoor environment where the air conditioner is located.
In this embodiment, the first temperature difference value is a calculation result obtained by subtracting the set temperature from the indoor environment temperature. In other embodiments, the first temperature difference may also be an absolute value of a calculation result obtained by subtracting the indoor environment temperature from the set temperature; the first temperature difference value may be an absolute value of a calculation result obtained by subtracting the set temperature from the indoor environment temperature.
Specifically, when the air conditioner is in a heating mode, the first temperature difference value is a calculation result obtained by subtracting the set temperature from the indoor environment temperature; when the air conditioner is in a refrigeration mode, the first temperature difference value is a calculated result obtained by subtracting the indoor environment from the set temperature.
Step S30, determining a target frequency of the compressor according to the first temperature difference value and the outdoor environment temperature;
the different first temperature differences and the different outdoor ambient temperatures may correspond to different target frequencies. In this embodiment, the target frequency is positively correlated with the first temperature difference and with the outdoor ambient temperature. The corresponding relation among the first temperature difference value, the outdoor environment temperature and the target frequency can be a preset fixed relation, and can also be a target corresponding relation selected from at least two preset corresponding relations according to the actual running condition of the air conditioner. The correspondence may have the form of a calculation formula, a mapping relation, or the like.
In this embodiment, when the current operation modes of the air conditioner are different, the corresponding relationship between the first temperature difference value, the outdoor environment temperature and the target frequency is different. Specifically, when the air conditioner is in the refrigeration mode, the target frequency corresponding to the first temperature difference value and the outdoor environment temperature can be determined based on the first corresponding relation; when the air conditioner is in the heating mode, the target frequency corresponding to the first temperature difference value and the outdoor environment temperature can be determined based on the second corresponding relation.
Wherein, when the indoor environment temperature and the outdoor environment temperature are detected in the process that the compressor is increased in frequency at an initial frequency or at a rate less than a set rate, the target frequency can be determined according to the indoor environment temperature and the outdoor environment temperature in a frequency range greater than or equal to the initial frequency or greater than or equal to a critical frequency corresponding to the frequency increasing rate.
And step S40, controlling the compressor to be up-converted to the target frequency.
Specifically, when the compressor is currently maintained in a closed state, the compressor can be lifted from the frequency of 0 to the target frequency for operation; when the compressor is currently in an on state, the compressor can be lifted from the current frequency to the target frequency for operation.
According to the control method of the air conditioner, when the compressor is started, the target frequency which is needed to be reached after the compressor is started is determined based on the first temperature difference value between the indoor environment temperature and the set temperature and the outdoor environment temperature, the compressor is controlled to be increased to the target frequency for operation, the first temperature difference value can accurately reflect the actual heat exchange requirement of an indoor user, and based on the method, the starting frequency of the compressor is not regulated and controlled based on the outdoor environment temperature alone, and the starting frequency of the compressor is regulated and controlled by further combining the actual heat exchange requirement of the indoor user, so that the matching of the heat exchange quantity input into the room by the air conditioner and the actual requirement of the user is ensured, and the regulation accuracy of the heat exchange quantity input into the room by the air conditioner when the compressor is started is effectively improved, so that the comfort of the indoor environment user is improved.
Further, based on the above embodiment, another embodiment of the control method of the air conditioner of the present application is provided. In this embodiment, referring to fig. 3, the step S30 includes:
step S31, determining the reference frequency of the compressor according to the outdoor environment temperature;
different outdoor ambient temperatures correspond to different reference frequencies. The reference frequency is positively correlated with the outdoor ambient temperature. Specifically, the reference frequency can be obtained by substituting the outdoor environment temperature into a preset functional relation between the outdoor temperature and the frequency, or the result of matching a preset mapping table between the outdoor temperature and the frequency can be queried through the outdoor environment temperature to serve as the reference frequency.
Step S32, determining the target frequency according to the first temperature difference value and the reference frequency;
specifically, the first temperature difference value can determine an adjustment value of the reference frequency, and the frequency adjustment value is obtained after the reference frequency is adjusted according to the adjustment value; the first temperature difference value can also be used as an initial adjustment value according to the difference value between the reference frequency and the preset frequency, and the initial adjustment value is adjusted to serve as the target frequency.
In this embodiment, the reference frequency includes a maximum frequency that the compressor is allowed to operate, where the maximum frequency is specifically an upper limit frequency of the compressor when the compressor is reliably operating under the current working condition. The preset frequency includes a preset minimum frequency of the compressor. The preset minimum frequency may be a preset fixed frequency, or may be a frequency selected from a plurality of preset minimum frequencies according to a current indoor fan rotation speed of the air conditioner. Determining a frequency difference value between the maximum frequency and a preset minimum frequency of the compressor, and determining a correction value according to the first temperature difference value and a set temperature difference value; correcting the frequency difference value according to the correction value to obtain a frequency adjustment value; and adjusting the preset minimum frequency according to the frequency adjustment value to obtain the target frequency.
The frequency difference is understood here to be the amplitude that the compressor allows to adjust, the amplitude being different with the outdoor ambient temperature.
The correction value can reflect the heat exchange quantity required by the current indoor environment. In this embodiment, the ratio of the first temperature difference value to the set temperature difference value is used as the correction value. In other embodiments, the difference between the first temperature difference and the set temperature difference may be used as the correction value.
In this embodiment, the product of the ratio of the first temperature difference value to the set temperature difference value and the frequency difference value is used as the frequency adjustment value, and the sum of the frequency adjustment value and the preset minimum frequency is used as the target frequency. In other embodiments, the preset adjustment value associated with the numerical interval between the difference between the first temperature difference value and the set temperature difference value may be used as the frequency adjustment value; in addition, a product or quotient between the preset minimum frequency and the frequency adjustment value can be used as the target frequency.
In addition to determining the target frequency by combining the maximum frequency, the minimum preset frequency and the first temperature difference value, in other embodiments, the adjustment coefficient may also be determined according to the first temperature difference value, and the target frequency may be obtained after adjustment directly according to the maximum frequency that the adjustment coefficient compressor is allowed to operate.
In this embodiment, the target frequency after the compressor is started is determined by combining the first temperature difference value and the reference frequency corresponding to the outdoor environment temperature, so that the reference frequency (such as the maximum frequency allowed to run) required by the current working condition can be corrected by combining the indoor actual heat exchange requirement, thereby further being beneficial to ensuring the accuracy of the obtained target frequency and improving the indoor comfort. The target frequency is determined by combining the maximum frequency, the preset minimum frequency and the set temperature difference value, so that the accuracy of the determined target frequency is improved, and the comfort of indoor users is improved further.
Further, in this embodiment, the target frequency is linearly and positively correlated with the first temperature difference value. The vertical axis deltat is defined to represent the first temperature difference value and the horizontal axis represents the target frequency. As shown in fig. 4 (a), the linear change relationship between the target frequency and the first temperature difference value during the heating operation of the air conditioner is shown, wherein the heating Fmax is the reference frequency determined based on the outdoor environment temperature during the heating operation; as shown in fig. 4 (b), the target frequency and the first temperature difference value are linearly changed when the air conditioner is in refrigeration operation, wherein the refrigeration Fmax is a reference frequency determined based on the outdoor environment temperature when the air conditioner is in refrigeration operation. Specifically, a linear positive correlation relationship between the target frequency and the first temperature difference value may be constructed according to the reference frequency, and if the reference frequency is different, the linear positive correlation relationship between the target frequency and the first temperature difference value is different. Specifically, in the linear positive correlation, the larger the reference frequency is, the larger the variation amount of the target frequency along with the variation of the first temperature difference value is, and the smaller the reference frequency is, the smaller the variation amount of the target frequency along with the variation of the first temperature difference value is. Based on this, can ensure that the target frequency of compressor can be with the accurate matching of the indoor comfortable heat transfer volume of demand that first difference in temperature value corresponds to further improve indoor environment's travelling comfort.
In other embodiments, the target frequency and the first temperature difference value may also be exponentially related.
In order to better understand the scheme related to the embodiment, a specific implementation manner of the air conditioner during heating operation is described below, specifically, the target frequency of starting the compressor may be determined by the first temperature difference and the following preset formula:
wherein Fmax1 is the target frequency, T1 is the indoor environment temperature, tsc is the set temperature, T1-Tsc is the first temperature difference value,to set the temperature difference value, < >>The correction value Fmax is the reference frequency (i.e. the maximum frequency), fmin is the preset minimum frequency, and Fmax-Fmin is the frequency difference;
the target frequency can be directly calculated by substituting the first temperature difference value into the preset formula, and other corresponding relations meeting the law represented by the preset formula can be used for determining the target frequency. It should be noted that the above formula is only used to explain the present embodiment, and is not intended to limit the scope of the present application, and any corresponding relationship between the target frequency and any other first temperature difference value conforming to the law shown by the above formula is within the description range of the present embodiment, for example, any mapping relationship, chart, algorithm model, etc. conforming to the law shown by the above formula.
Further, based on any one of the above embodiments, a further embodiment of the control method of the air conditioner of the present application is provided. In this embodiment, referring to fig. 5, the step S30 includes:
step S301, determining a second temperature difference value between the indoor environment temperature and the outdoor environment temperature;
the second temperature difference value is a calculated result obtained by subtracting the indoor environment temperature from the outdoor environment temperature when the air conditioner is in refrigeration operation; the second temperature difference value is a calculated result obtained by subtracting the outdoor environment temperature from the indoor environment temperature when the air conditioner is in heating operation.
Step S302, obtaining a target corresponding relation according to the second temperature difference value, wherein the target corresponding relation is a corresponding relation among the first temperature difference value, the outdoor environment temperature and the target frequency;
the different second temperature difference values correspond to different target corresponding relations, and the target corresponding relations can comprise a calculation formula, a mapping relation and other forms. In this embodiment, when the second temperature difference value is greater than the target temperature difference, a first preset corresponding relationship is obtained as the target corresponding relationship; when the second temperature difference value is smaller than or equal to a target temperature difference value, a second preset corresponding relation is obtained as the target corresponding relation; the first target frequency is greater than the second target frequency, the first target frequency is a target frequency corresponding to the first temperature difference value and the outdoor environment temperature in the first preset corresponding relation, and the second target frequency is a target frequency corresponding to the first temperature difference value and the outdoor environment temperature in the second preset corresponding relation. The target temperature difference may be a preset fixed temperature difference, or may be a temperature difference determined according to an actual operation condition of the air conditioner, for example, the first temperature difference value may be used as the target temperature difference.
In other embodiments, a plurality of value intervals may be preset, each value interval is associated with a first temperature difference value, a preset corresponding relationship between the outdoor environment temperature and the target frequency, and the preset corresponding relationship associated with different value intervals is different.
