The present application will be described in further detail with reference to the following drawings and examples.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
The embodiment of the application provides a control method of an air conditioner, and the air conditioner is used for adjusting the temperature, the humidity and the like of an environment. The air conditioner can be a single-cooling air conditioner or a cooling and heating dual-purpose air conditioner, and the air conditioner can be in the form of a wall-mounted air conditioner, a cabinet air conditioner, a window air conditioner or a ceiling air conditioner, and the like, and the embodiment of the application is not particularly limited to this.
It can be understood that the air conditioner includes an air conditioner external unit and an air conditioner internal unit, which may be separate structures, for example, the air conditioner internal unit is disposed indoors and the air conditioner external unit is disposed outdoors. The air conditioner external unit and the air conditioner internal unit can also be of integrated structures, namely the air conditioner internal unit and the air conditioner external unit are arranged together to form an integrated air conditioner such as a mobile air conditioner, a portable air conditioner, a window air conditioner and the like. It should be noted that, for the integrated air conditioner, it has advantages such as convenient installation and removal, but because the distance of condenser and evaporimeter is close, can only partially refrigerate or heat, in addition, because the structure size is little, is sensitive to system load fluctuation, and is close to the user, noise, vibration, refrigeration or heating volume change etc. often directly influence user's use impression.
The air conditioner according to the embodiment of the present application is an inverter air conditioner.
In the related art, the air conditioner often sets a fixed frequency increasing and decreasing speed of the compressor and the fan in the parameter table. In addition, considering the pressure of the air conditioning system, for the refrigerating system, the gear is switched every time, if the frequency is reduced, the frequency of the compressor is reduced firstly, and the frequency of the compressor is reduced after the fan. If the frequency is increased, the frequency of the fan is increased firstly, the frequency of the fan is increased after the compressor, and the frequency increasing and decreasing speeds of the compressor and the fan are fixed. So operate, though help to refrigerating system pressure reduction, owing to have the lift process of long-time compressor and fan, the complete machine changes the noise duration long, is unfavorable for user experience.
Based on this, the embodiment of the present application provides a control method of an air conditioner, as shown in fig. 1, the method including:
step 101, a gear shift instruction is obtained.
In the embodiment of the application, the air conditioner is provided with at least two gears, and each gear is provided with a corresponding target frequency and a corresponding target rotating speed.
Illustratively, the air conditioner has four gears, respectively: table 1 shows target frequencies and target rotational speeds corresponding to the high gear, the middle gear, and the low gear.
TABLE 1
Gear position Target frequency Target rotational speed
(Strong) Compressor frequency FR1 Fan speed PR1
Height of Compressor frequency FR2 Fan speed PR2
In Compressor frequency FR3 Fan speed PR3
Is low in Compressor frequency FR4 Fan speed PR4
It can be understood that FR1 > FR2 > FR3 > FR4, PR1 > PR2 > PR3 > PR4, i.e. the compressor frequency of the strong gear is greater than the compressor frequency of the high gear, the fan speed of the strong gear is greater than the fan speed of the high gear, and so on.
It should be noted that the rotation speed of the fan may be the rotation speed of the inner fan, the rotation speed of the outer fan, or the rotation speed of the inner fan and the rotation speed of the outer fan.
It is understood that in other embodiments, the number of the gears of the air conditioner may be three, five or other, which is not limited in the embodiments of the present application.
It should be noted that the gear of the air conditioner may be a physical gear set on a remote controller or a touch panel of the air conditioner, or may also be a logical gear set by the air conditioner based on an operating program, that is, the gear switching instruction may be an instruction generated based on switching of the physical gear, or may also be an instruction corresponding to switching of the logical gear determined based on the operating program, which is not limited in this embodiment of the application.
For example, the air conditioner may receive an instruction input by a user, so as to obtain a corresponding gear shift instruction, or the air conditioner may generate the gear shift instruction based on a change of an operating parameter such as an ambient temperature, which is not limited in this embodiment of the present application.
And 102, determining the target frequency of the compressor operation and the target rotating speed of the fan operation based on the gear switching instruction.
It can be understood that the air conditioner stores a mapping relationship between gears and target frequencies and target rotating speeds corresponding to the gears in advance, and the air conditioner can determine the target frequency of the compressor operation and the target rotating speed of the fan operation based on the acquired gear switching instruction and the mapping relationship.
And 103, determining the frequency conversion duration of the compressor based on the current frequency, the target frequency and the preset frequency conversion rate of the compressor.
Here, the air conditioner may obtain a current frequency and a preset variable frequency rate at which the compressor operates, and determine a variable frequency duration of the compressor based on the current frequency, the target frequency, and the preset variable frequency rate.
And step 104, determining the speed change rate of the fan based on the frequency conversion duration, the current rotating speed of the fan and the target rotating speed.
Here, the air conditioner may obtain a current rotation speed of the fan, and determine a speed change rate of the fan based on the frequency conversion duration, the current rotation speed, and the target rotation speed determined in step 103. Under the prerequisite that frequency conversion rate was preset promptly, the variable speed rate of dynamic adjustment fan during based on the frequency conversion of compressor for the variable speed rate of fan matches with the frequency conversion rate of compressor, thereby can the frequency conversion process of synchronous compressor and the variable speed process of fan, and the noise that effectively reduces compressor frequency conversion and fan variable speed lasts for a long time, does benefit to and promotes user experience.
For example, the determining the variable frequency duration of the compressor based on the current frequency of the compressor operation, the target frequency and the preset variable frequency rate includes:
if the current frequency is determined to be greater than the target frequency, selecting a preset down-conversion rate, and dividing the preset down-conversion rate by the preset down-conversion rate based on the difference between the current frequency and the target frequency to obtain a conversion duration; alternatively, the first and second electrodes may be,
and if the current frequency is determined to be smaller than the target frequency, selecting a preset frequency-raising and frequency-converting rate, and dividing the frequency-raising and frequency-converting rate by the difference between the target frequency and the current frequency to obtain the frequency-converting duration.
It will be appreciated that the predetermined down conversion rate may be the same as or different from the predetermined up conversion rate.
Illustratively, the preset frequency increasing and frequency converting rate is less than or equal to 0.5Hz/s (Hertz per second), so that the phenomenon that the frequency increasing and frequency converting rate of the compressor is too large and the noise of the compressor is too large can be avoided.
Illustratively, the preset down-conversion rate may be 1Hz/s.
For example, the determining the speed change rate of the fan based on the frequency conversion duration, the current rotating speed of the fan and the target rotating speed comprises:
and dividing the absolute value of the difference between the current rotating speed and the target rotating speed by the variable frequency time length to obtain the variable speed rate.
It is understood that the control method further includes:
and controlling the compressor to be switched to the target frequency based on the variable frequency rate, and controlling the fan to be switched to the target rotating speed based on the variable speed rate.
Exemplarily, the compressor can be synchronously controlled to be switched to the target frequency based on the variable frequency rate, and the fan is synchronously controlled to be switched to the target rotating speed based on the variable speed rate, so that the variable frequency process of the compressor and the variable speed process of the fan are synchronous, the duration of noise in the gear switching process is reduced, and the user experience is favorably improved.
In an application example, as shown in fig. 2, a control method of an air conditioner includes:
step 201, determining a target frequency of a compressor and a target rotating speed of a fan according to a gear input by a user.
For example, when the gear is set to the high gear, the target frequency of the compressor is FR2, and the target rotation speed of the fan is PR2.
And 202, acquiring the actual operating frequency Fr of the compressor and the actual operating rotating speed Pr of the fan.
Step 203, judging whether the current actual operating frequency Fr of the compressor is greater than the target frequency FR2 of the compressor, if not, executing step 204; if yes, go to step 206.
And 204, determining that the compressor needs to be boosted, and determining the frequency conversion duration based on a preset frequency boosting and frequency conversion rate.
Here, the calculation formula of obtaining the frequency conversion time period required for the frequency conversion of the compressor as T according to the current operating frequency Fr of the compressor, the target frequency Fr2, and the frequency conversion rate Kacc of the compressor set in the parameter table is as shown in the following formula (1):
Figure BDA0003142484770000081
and step 205, determining the speed change rate of the fan based on the frequency conversion duration, the current running rotating speed of the fan and the target rotating speed.

and step 206, determining that the compressor needs to be subjected to frequency reduction, and determining the frequency conversion duration based on the preset frequency reduction and frequency conversion rate.

Figure BDA0003142484770000091
and step 207, determining the speed change rate of the fan based on the frequency conversion duration, the current running rotating speed of the fan and the target rotating speed.
According to the frequency conversion time length T of the compressor calculated in the step 206, the current running fan rotating speed Pr and the target rotating speed PR6 of the fan, the speed change rate of the fan is calculated as shown in the following formula (4):
Figure BDA0003142484770000092
and 208, controlling the frequency conversion of the compressor and the speed change synchronization of the fan according to the speed change rate of the fan.
Here, the fan is controlled to shift to the target rotation speed according to the speed change rate of the fan calculated in step 205 or step 207, and the compressor is synchronously controlled to perform frequency conversion to the target frequency based on the preset frequency conversion rate, so that the frequency conversion of the compressor and the speed change of the fan are synchronized.
It can be understood that, if the target frequency of the compressor changes due to the gear change of the user or the frequency limit during the operation process, the above steps 201 to 208 are repeated to switch the operation frequency of the compressor and the operation speed of the fan.
It can be understood that, according to the control method of the application example, on the premise that the frequency conversion rate is preset, the speed change rate of the fan is dynamically adjusted based on the frequency conversion duration of the compressor, so that the speed change rate of the fan is matched with the frequency conversion rate of the compressor, the frequency conversion process of the compressor and the speed change process of the fan can be synchronized, the duration of the noise generated by the frequency conversion of the compressor and the speed change of the fan is effectively reduced, and the user experience is favorably improved.
