Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the invention.
When the air conditioner is used, when the operating frequency of the compressor is adjusted, if the compressor is in high-frequency operation, the compressor can reach a stable state generally in a relatively long time, and if the compressor is in low-frequency operation, the operating frequency fluctuates back and forth in the adjusting process, so that the compressor is not easy to reach the stable state. In fact, when the compressor is in different frequency bands, the sensitivity to frequency changes is different, and the influence of the same frequency value of frequency increasing or frequency reducing on the low frequency band is greater than the influence on the high frequency band.
Aiming at the problems, the frequency adjusting curve is introduced, the running frequency of the compressor is divided into a plurality of continuous frequency intervals, in each frequency interval, the running frequency of the compressor is positively correlated with the replacement frequency, and the actual running frequency of the compressor is adjusted by adjusting the replacement frequency.
The present embodiment provides a method for adjusting the frequency of a compressor in stages, as shown in fig. 1, the method including:
s100, acquiring the current actual frequency and the target frequency of the compressor;
s200, determining a first replacement frequency corresponding to the current actual frequency and a second replacement frequency corresponding to the target frequency according to the frequency regulation curve;
and S300, adjusting the replacement frequency from the first replacement frequency to the second replacement frequency to adjust the running frequency of the compressor from the current actual frequency to the target frequency.
The compressor frequency segmentation adjusting method provided by the embodiment segments the operating frequency of the compressor, so that the operating frequency in different frequency intervals can have different corresponding relations with the replacing frequency, the sensitivity of a low frequency band can be reduced and the sensitivity of a high frequency band can be improved by adjusting the replacing frequency, the stable or quick adjustment of the operating frequency is realized, the operating frequency of the compressor is more finely controlled, and the operation of the compressor is more stable.
Specifically, in the present embodiment, the higher the operating frequency in the frequency interval is, the larger the slope of the frequency adjustment curve is. In other words, the slope of the frequency adjustment curve is positively correlated with the frequency of the frequency interval, and the lower the operating frequency in the frequency interval is, the smaller the slope of the corresponding frequency adjustment curve is; the higher the operating frequency within the frequency interval, the greater the slope of the corresponding frequency adjustment curve. That is, the lower the operation frequency in the frequency interval is, the larger the alternative frequency adjustment amount corresponding to the same operation frequency adjustment amount is in the frequency interval compared with other frequency intervals, so that the sensitivity to the frequency change can be reduced, and the adjustment of the operation frequency of the compressor is more stable; the higher the operation frequency in the frequency interval is, the smaller the alternative frequency regulating quantity corresponding to the same operation frequency regulating quantity is compared with other frequency intervals in the frequency interval, so that the sensitivity to the frequency change can be improved, and the operation frequency of the compressor can be regulated more quickly.
Specifically, in the method provided in this embodiment, as shown in fig. 2, in the frequency adjustment curve, in each frequency interval, the operating frequency of the compressor and the replacement frequency are both in a linear relationship. In this way, in the same frequency interval, the change amount of the replacement frequency corresponding to the same operation frequency change amount is the same, and the slope of the frequency adjustment curve is unchanged. By the arrangement, the frequency regulation rules are consistent in the same frequency interval, and the regulation is simple and easy.
More specifically, the present embodiment provides a method, wherein the operating frequency of the compressor and the replacement frequency satisfy the following relation:
F＝f*K i +C i ，(1)
wherein F is the operating frequency of the compressor; f is the replacement frequency; i isAccording to the sequence of the frequencies from low to high, the sequence number of the frequency interval, i is a natural number; k is i An adjustment coefficient for the ith frequency interval; c i The offset for the ith frequency bin is used to make the frequency adjustment curves for adjacent frequency bins continuous at the segmentation point. The adjustment coefficient of the frequency interval corresponds to the slope of the frequency adjustment curve, and the introduction of the offset enables the whole frequency adjustment curve to be continuous, so that the adjustment of the running frequency of the compressor is continuously adjustable.
The above-mentioned alternative frequency f is exemplified by the frequency number f (i) adjusted by the controller, K i To adjust the coefficients, # i Frequency F of compressor operation, frequency F (i) adjusted by controller, and adjustment coefficient K i The functional relationship of (a) is as follows:
F(i)＝f(i)·K i +ψ i (2)
wherein, when i is more than or equal to 0 and less than n 1 When, K i ＝K 1 ；n 1 ≤i＜n 2 When, K i ＝K 2 ；n 2 ≤i＜n 3 When, K i ＝K 3 ；……
n 1 、n 2 、n 3 \8230, a point of frequency segmentation, K 1 、K 2 、K 3 823060 i The continuity of the curve is guaranteed for the phase offset of each segment.
Taking (75, 30), (112.5, 60) and (137.5, 90) as segmentation points of the frequency regulation curve, and regulating coefficient K of each frequency interval i Respectively take 0.4, 0.8 and 1.2, namely K 1 ＝0.4，K 2 ＝0.8，K 3 =1.2, three straight lines L shown in fig. 2 can be obtained 1 、L 2 ' and L 3 ' phase shift amount psi of each frequency interval i Respectively 0, -30, -75, i.e. psi 1 ＝0，ψ 2 ＝-30，ψ 3 = -75, i.e. the product obtained is represented by L in FIG. 2 1 、L 2 And L 3 The resulting broken line, i.e. the frequency adjustment curve shown in fig. 3.
As is apparent from fig. 3, the same replacement frequency Δ F is adjusted, and in each frequency interval, the actual operating frequency of the corresponding compressor varies by Δ F, and in a high frequency band, i.e., in a frequency interval with a higher operating frequency, Δ F corresponding to the same Δ F is larger; in the low frequency band, that is, in the frequency interval with lower operating frequency, Δ F corresponding to the same Δ F is small, so that the method provided by this embodiment adjusts the low frequency band more finely, can make the compressor stable and not easy to generate large fluctuation, adjusts the high frequency band more rapidly, and can shorten the frequency adjustment time when the compressor is in the high frequency band.
It should be noted that, in other embodiments of the present application, in the frequency adjustment curve, the operating frequency of the compressor and the replacement frequency are in a non-linear relationship in each frequency interval. By the arrangement, in each frequency interval, the slopes of the frequency adjusting curves corresponding to different operating frequencies are different, so that the operating frequency of the compressor is more finely adjusted, and the operation stability of the compressor is further improved. For example, in other embodiments of the present application, the frequency adjustment curve may be continuous and conductive in the whole operation frequency range, so that when the target frequency and the current actual frequency of the compressor belong to different frequency intervals, the operation frequency of the compressor can still be smoothly transited, and the operation is more stable.
It should be noted that, in other embodiments of the present application, in the frequency adjustment curve, the operating frequency of the compressor and the replacement frequency may also be in a linear relationship within a part of the frequency interval; in another part of the frequency interval, the running frequency of the compressor and the replacement frequency are in a non-linear relationship. So set up, when the operating frequency of compressor is in some frequency intervals, can adopt more simple and easy linear regulation, and when the operating frequency of compressor is in another some frequency intervals, can adopt more meticulous non-linear regulation. For example: if the compressor is operated at high frequency, linear regulation can be adopted because the high frequency band has low sensitivity to frequency change, while if the compressor is operated at low frequency, nonlinear regulation can be adopted because the low frequency band has high sensitivity to frequency change, thus taking into account the feasibility of regulation and the smoothness of operation of the compressor.

and the adjusting module 300 is used for adjusting the replacement frequency from the first replacement frequency to the second replacement frequency so as to adjust the operating frequency of the compressor from the current actual frequency to the target frequency.
