[0034] see figure 1 , the present embodiment provides a compressor frequency control method for an air conditioner, including:

[0035] S100: During the system test process of the air conditioner, in the case that the air conditioner has a frequency limitation problem of the compressor, by adjusting the frequency related parameters of the air conditioner, the frequency of the compressor of the air conditioner is controlled;

[0036] Wherein, the frequency-related parameters include: power frequency limit control coefficient α and / or internal fan gear correction upper limit frequency coefficient β.

[0037] In this embodiment, during the system test of the air conditioner, the air conditioner has a problem of frequency limitation of the compressor. The cost-saving electrolytic capacitor controller that replaces large capacitors with film capacitors has been developed and applied, but the use of non-electrolytic capacitor controllers is likely to cause the frequency limit of th...

no. 2 example

[0044] In a specific embodiment, when the frequency-related parameters include the power frequency-limiting control coefficient α, the adjustment range of the power-frequency-limiting control coefficient α is α±K1, where K1 is a constant; when the frequency-related parameters include the internal fan In the case of the gear correction upper limit frequency coefficient β, the adjustment range of the internal fan gear correction upper limit frequency coefficient β is β±K2, where K2 is a constant.

[0045] In this embodiment, the parameter range values ​​of the power frequency limiting control coefficient α and the internal fan gear correction upper limit frequency coefficient β are limited. That is to say, the adjustment of frequency-related parameters is also included in the range value of this parameter.

[0046] Preferably, when the frequency-related parameters include the power frequency-limiting control coefficient α, K1=1, that is, the adjustment range of the power frequen...

[0050] In a specific embodiment, the compressor frequency of the air conditioner is controlled by adjusting frequency-related parameters of the air conditioner, including:

[0051] S110: Control the compressor frequency of the air conditioner by adjusting one of the power frequency limiting control coefficient α and the internal fan gear correction upper limit frequency coefficient β;

[0052] S120: When the compressor frequency does not reach the target frequency, control the compressor frequency of the air conditioner by adjusting the other one of the power frequency limit control coefficient α and the internal fan gear correction upper limit frequency coefficient β.

[0053] It should be noted that the compressor frequency is the frequency detected by the compressor in real time, and the target frequency is the compressor frequency when the air conditioner is working normally. When the compressor frequency reaches the target frequency, the air conditioner is running normally...

Abstract

The invention provides an air conditioner, a control method and device of the air conditioner and a readable storage medium. The method comprises the steps that in the system testing process of the air conditioner, under the condition that the compressor frequency limiting problem exists in the air conditioner, the compressor frequency of the air conditioner is controlled by adjusting frequency related parameters of the air conditioner; wherein the frequency related parameters comprise a power frequency limiting control coefficient alpha and / or an inner fan gear correction upper limit frequency coefficient beta. The problem that the frequency limiting problem of the compressor of the air conditioner cannot be effectively adjusted according to the technical scheme in the related technology is solved.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to an air conditioner, a control method thereof, a control device and a readable storage medium. Background technique [0002] With the mainstream of cost reduction in air-conditioning design, cost-reducing non-electrolytic capacitor controllers that replace large capacitors with film capacitors have been developed and applied. However, the use of an electrolytic capacitor controller is likely to cause problems such as large busbar voltage fluctuations and low output effective voltage; at the same time, the periodic change of the maximum voltage will cause large fluctuations in the q-axis current, large output torque fluctuations, and other derivative problems, which may easily cause air conditioning The problem that the frequency of the compressor is limited during the system test of the compressor. [0003] In the process of air conditioner testing, there are gen...
