[0036] see figure 2 , which is an air conditioner control method provided in the first embodiment of the present invention, the air conditioner control method includes:

[0037] Step S10: Get the input voltage value V ac and the instantaneous current value I p .

[0038] see image 3 , the input voltage value V of the AC power supply of the air conditioner can be obtained through the sampling circuit ac and the instantaneous current value I p .

[0039] Step S20: According to the instantaneous current value I p Get the effective current value I ac .

[0040] The effective current value I ac It is calculated and predicted based on multiple instantaneous current values ​​obtained continuously before, or in other words, the effective current value corresponding to the instantaneous current value at the current moment is obtained through prediction of the multiple instantaneous current values.

[0041] Step S30: According to the input voltage value V ac And effective c...

Abstract

The invention provides an air conditioner control method and device, and an air conditioner. The air conditioner control method includes: obtaining an input voltage value V ac and the instantaneous current value I p ; According to the instantaneous current value I p Get the effective current value I ac ; According to the input voltage value V ac And effective current ratio K, control reduces the running frequency of compressor; Wherein, described K=I p / I ac . The invention solves the problem that the air conditioner cannot operate reliably due to abnormal power supply voltage.

Description

technical field [0001] The present invention relates to the technical field of air conditioner control, in particular to an air conditioner control method, an air conditioner control device and an air conditioner. Background technique [0002] Air conditioners are used more and more widely, especially in more and more harsh environments. [0003] Wherein, when the power supply voltage is abnormal, the power supply protection is often triggered to cause the air conditioner to shut down; therefore, in this case, the air conditioner cannot maintain reliable operation and cannot meet user needs. Contents of the invention [0004] The invention solves the problem that the air conditioner cannot operate reliably due to abnormal power supply voltage. [0005] In order to solve the above problems, on the one hand, the present invention provides an air conditioner control method, including: obtaining the input voltage value V ac and the instantaneous current value I p ; Accordin...
