Detailed Description
The invention provides a compressor operation frequency adjusting method, a storage medium and an air conditioner, and in order to make the purpose, technical scheme and effect of the invention clearer and clearer, the invention is further described in detail below by referring to the attached drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The method for adjusting the running frequency of the compressor can be applied to equipment comprising the compressor, such as an air conditioner, a refrigerator and the like.
Example one
The present embodiment provides a compressor operation frequency adjusting method, as shown in fig. 1, the compressor operation frequency adjusting method including:
s100, acquiring a starting frequency, a target frequency and a target duration of a compressor, and acquiring a frequency regulation acceleration of the compressor according to the starting frequency, the target frequency and the target duration.
Specifically, in order to quickly implement cooling or heating after starting up, the compressor needs to be set to keep running at a higher running frequency after starting up, the target frequency is the running frequency that the compressor needs to reach and keep after starting up for a period of time, the starting frequency is the preset running frequency of the compressor at the starting time, the target duration is the duration that the compressor reaches the target frequency after starting up, that is, the compressor needs to be increased from the starting frequency to the running frequency within the target duration in the starting up process. The target frequency, the starting frequency and the target duration may be pre-stored in a memory of the device corresponding to the compressor, and the starting frequency, the target frequency and the target duration are read from the memory after the device is started.
The frequency adjustment acceleration reflects the change condition of the adjustment speed when the operation frequency of the compressor is adjusted, and when the operation frequency of the compressor is increased, if the frequency adjustment acceleration is greater than zero, the adjustment speed for adjusting the operation frequency of the compressor is higher and higher, that is, the operation frequency of the compressor changes more and more violently, and the speed for increasing the operation frequency of the compressor is higher and higher; if the frequency adjustment acceleration is smaller than zero, the adjustment speed for adjusting the operating frequency of the compressor is lower and lower, that is, the frequency change of the compressor is smoother and smoother, and the speed for increasing the operating frequency of the compressor is slower. The frequency adjustment acceleration is calculated according to a preset formula according to the starting frequency, the target frequency and the target duration, and will be described in detail later.
S200, adjusting the running frequency of the compressor according to the frequency adjusting acceleration so that the compressor is started at the starting frequency and reaches the target frequency after the target duration.
As described above, the frequency adjustment acceleration reflects a change of the adjustment speed when the operating frequency of the compressor is adjusted, that is, reflects a severity of a change of the operating frequency of the compressor, and adjusting the operating frequency of the compressor according to the frequency adjustment acceleration enables the operating frequency of the compressor to change according to the adjustment speed corresponding to the frequency adjustment acceleration, so as to achieve the purpose that the compressor is started at the starting frequency and reaches the target frequency after the target time length.
Specifically, there are multiple times within the target duration, and the adjusting the operating frequency of the compressor according to the frequency adjustment acceleration specifically includes:
s210, acquiring the running frequency of the compressor at the corresponding moment at each moment according to the frequency regulation acceleration.
The moment operating frequency is the operating frequency of the compressor at the moment. After the frequency adjustment acceleration is obtained, the time operating frequencies respectively corresponding to the compressor at each time can be obtained according to a preset formula. Specifically, in the present embodiment, in order to achieve that the compressor can reach the target frequency within the target time period after starting, and at the same time, prevent the operating frequency of the compressor from increasing too fast, which affects the reliability of the compressor, the target time period is divided into two stages: the compressor comprises a first stage and a second stage, wherein the first stage is a quick adjustment stage, the second stage is a slow adjustment stage, the operating frequency of the compressor is changed quickly and rises quickly in the first stage, and is changed slowly and rises slowly in the second stage. The frequency adjustment acceleration comprises a first adjustment acceleration and a second adjustment acceleration, and the first stage and the second stage respectively correspond to the first adjustment acceleration and the second adjustment acceleration. And for different stages, adjusting the acceleration according to different frequencies to obtain the running frequency at the moment.
Specifically, the obtaining of the time operating frequencies respectively corresponding to the compressor at each time according to the frequency adjustment acceleration includes:
s211, when the moment is in the first stage, obtaining a moment operating frequency corresponding to the moment according to the first regulation acceleration;
and S212, when the moment is in the second stage, acquiring the moment operating frequency corresponding to the moment according to the second adjustment acceleration.
In one possible implementation, the first conditioned acceleration is greater than zero, the second conditioned acceleration is less than zero, that is, in the first stage, when the operating frequency of the compressor is adjusted according to the first adjusting acceleration, the frequency of the compressor is changed more and more in unit time, i.e., the operating frequency of the compressor is changed at a fast speed, the operating frequency of the compressor is gradually changed from a slow increase to a fast increase, in the second stage, when the operating frequency of the compressor is adjusted according to the second adjusting acceleration, the change amplitude of the operating frequency of the compressor in unit time is smaller and smaller, that is, the operating frequency of the compressor is slowly changed, and then the operating frequency of the compressor is gradually changed from a fast increase to a slow increase. Therefore, the running frequency of the compressor is slowly changed when the compressor is started and is close to the target frequency, and the running frequency is quickly changed in the middle part, so that the target frequency can be reached within the target time length, the phenomenon that the running frequency of the compressor is changed too violently when the compressor starts to change and when the compressor finishes to change so as to bring overshoot to the compressor and cause excessive vibration of the compressor can be prevented, and the reliability of the compressor in the starting process is improved.
In this embodiment, the time operating frequency obtained according to the frequency adjustment acceleration is obtained by calculation according to a preset formula, and the calculation formula is different according to different stages of the time.
Specifically, when the time is in the first stage, the calculation formula for obtaining the time operating frequency corresponding to the time according to the first adjustment acceleration is as follows:
Figure BDA0002326522960000071
wherein t is a time interval between the time and the compressor starting time, for example, the time corresponds to 3ms after the compressor is started, and then t is 3; t is1Is the duration of the first stage; freq (t) is the time running frequency corresponding to the time; a is1For the first adjusted acceleration; freqminIs the start-up frequency.
When the time is in the second stage, the calculation formula for obtaining the time operating frequency corresponding to the time according to the second adjustment acceleration is as follows:
Figure BDA0002326522960000072
wherein t is the time interval between the moment and the starting moment of the compressor; t is1Is the duration of the first stage; t is the target duration; freq (t) is the time running frequency corresponding to the time; a is2For the second regulation of acceleration, a1For the first adjusted acceleration; freqminIs the start-up frequency.
The adjusting the operating frequency of the compressor according to the frequency adjustment acceleration further comprises:
s220, adjusting the operation frequency of the compressor so that the compressor reaches the operation frequency at the moment corresponding to each moment at each moment.
After the moment operating frequencies respectively corresponding to the moments of the compressor are obtained according to the frequency adjustment acceleration, the operating frequencies of the compressor can be adjusted according to the moment operating frequencies, so that the compressor respectively reaches the moment operating frequencies respectively corresponding to the moments of the compressor at the moments. When the time is the starting time of the compressor, that is, the time interval between the time and the starting time of the compressor is 0, that is, T in the above formula is 0, the time operating frequency is equal to the starting frequency, and when the time interval between the time and the starting time of the compressor is the target time length, that is, T in the above formula is T, the time operating frequency is equal to the target frequency, so that the compressor is started at the starting frequency and reaches the target frequency after the target time length is achieved.
The time intervals may be fixed, for example, the time interval between each time and the last time may be 1ms or 2 ms. The operation frequency of the compressor is adjusted, so that the operation frequency of the compressor at each moment reaches the moment operation frequency corresponding to each moment respectively at each moment, the operation frequency can be obtained after the moment operation frequency corresponding to all the moments is obtained, the moment operation frequency corresponding to each moment is read after the compressor is started, and the operation frequency of the compressor is adjusted according to the moment operation frequency. The adjusting of the operating frequency of the compressor so that the compressor respectively reaches the time operating frequency corresponding to each time at each time may also be performed in real time after the compressor is started, that is, the time operating frequency corresponding to the next time is obtained in real time at the current time, and the operating frequency of the compressor is adjusted so that the compressor reaches the time operating frequency at the next time.
The operation frequency of the compressor can be adjusted through an inverter, specifically, after the time operation frequency is obtained, a pulse width modulation wave is generated according to the time operation frequency and is input to the inverter corresponding to the compressor, and the inverter controls the compressor to operate according to the time operation frequency according to the pulse width modulation wave, so as to adjust the operation frequency of the compressor. This is the prior art and will not be described herein.
It is easy to find out from the above formula that, in order to achieve a start of the compressor at the starting frequency and a attainment of the target frequency after the target duration, the first and second modulated accelerations are related to the duration of the first and second phases, which in one possible implementation is equal to the duration of the second phase, i.e. in the above formula
Figure BDA0002326522960000091
When the duration of the first phase is equal to the duration of the second phase, the first adjustment acceleration is calculated according to the formula:
Figure BDA0002326522960000092
wherein, a1For the first adjusted acceleration; freqmaxIs the target frequency; freqminIs the starting frequency, T is the targetLength, the second regulated acceleration is calculated by the formula a2＝-a1Wherein a is2For the second regulation of acceleration, a1The acceleration is adjusted for the first adjustment.
In other possible implementations, depending on the ratio of the duration of the first phase to the duration of the second phase in the target duration, the first adjustment acceleration and the second adjustment acceleration may have other calculation formulas, for example, when the duration of the second phase is twice the duration of the first phase, that is, when the duration of the first phase is one-third of the target duration,
Figure BDA0002326522960000093
the first adjustment acceleration is calculated by the formula:
Figure BDA0002326522960000094
the calculation formula of the second adjustment acceleration is: a is2＝-2a1. A person skilled in the art may configure the first stage and the second stage according to actual requirements, so as to set the first adjustment acceleration and the second adjustment acceleration which are different correspondingly.
In summary, the present embodiment provides a method for adjusting an operating frequency of a compressor, where the target time duration is divided into two stages, a first adjustment acceleration corresponding to the first stage is greater than zero, and a first adjustment acceleration corresponding to the second stage is smaller than zero, so that the operating frequency of the compressor changes slowly when the compressor is just started and approaches the target frequency, and changes rapidly in the middle part, thereby meeting the requirement of reaching the target frequency within the target time duration, preventing overshoot from being brought to the compressor due to too severe change of the operating frequency of the compressor when the compressor starts changing and when the compressor finishes changing, and improving reliability of the compressor in the starting process. As shown in fig. 2, fig. 2 is a graph of the variation of the operating frequency of the compressor when the operating frequency of the compressor is adjusted according to the method for adjusting the operating frequency of the compressor provided in this embodiment (the starting frequency corresponding to the curve in the graph is 15Hz, the target frequency is 60Hz, and the target time length is 3s), it can be seen that the curve is very gentle at the beginning (starting time) and the end (reaching the target frequency), and the slope is larger in the middle part, which indicates that the operating frequency of the compressor slowly increases at the starting time and reaching the target frequency, and rapidly increases in the middle part, which satisfies the target frequency within the target time length, and prevents the operating frequency from being too severe at the beginning and ending of the variation, thereby improving the reliability of the compressor during the starting process.
