Specific embodiment
It should be appreciated that described herein, specific examples are only used to explain the present invention, is not intended to limit the present invention.
The present invention provides a kind of air-conditioner control method, referring to Fig.1, in the air condition of that present invention control method first embodiment
In, which includes:
Step S10 obtains the level of power consumption restricted driving instruction and corresponds to when receiving preset level of power consumption restricted driving instruction
Frequency limit current value;
Air-conditioner control method provided in an embodiment of the present invention is mainly used in fixed frequency air conditioner, for in fixed frequency air conditioner
The working frequency of compressor is controlled.
The instruction of restricting driving of above-mentioned preset level of power consumption can be issued by user by remote control, can also by host computer according to
Preset rules condition is configured, and when meeting preset condition, host computer is actively restricted driving to air-conditioning sending power consumption grade and instructed.
Above-mentioned frequency limit current value is air-conditioning after receiving above-mentioned level of power consumption restricted driving instruction, and air-conditioning allows the maximum run
Current value, the i.e. upper limit value of air conditioner electric current.Specifically, the level of power consumption that different stage can be set restricts driving instruction to realize
Different degrees of current limliting, the i.e. level of power consumption of different stage, which are restricted driving, instructs corresponding different size of frequency limit current value.
Step S20, being restricted driving to instruct according to the level of power consumption obtains the current complete machine current value of air-conditioning;
In the present embodiment, after receiving above-mentioned level of power consumption restricted driving instruction, currently detected air-conditioning can be actively obtained
Complete machine current value.Specifically, current detection module real-time detection air-conditioning current operating conditions are usually preset in air conditioner
The current value of lower complete machine then obtains the current detection module and is detected when air-conditioning receives above-mentioned level of power consumption restricted driving instruction
Current value.
Step S30, judges whether the current complete machine current value is greater than the frequency limit current value;
Step S40 reduces the frequency of compressor when the current complete machine current value is greater than the frequency limit current value,
So that the complete machine current value is less than or equal to the frequency limit current value.
After getting above-mentioned complete machine current value and frequency limit current value, can by the complete machine current value and frequency limit current value into
Row compares, and whether the complete machine current value that judgement currently gets air-conditioning is greater than frequency limit current value.If the complete machine electricity currently got
Flow valuve is less than or equal to frequency limit current value, then it represents that power consumption is smaller under air-conditioning current working status, does not need to carry out current limliting;If working as
Before the complete machine current value that gets be greater than frequency limit current value, then it represents that power consumption is larger under air-conditioning current working status, needs to carry out
Current limliting.When needing to carry out current limliting, the power consumption of air conditioner can be reduced by reducing the frequency of compressor, and then reduce
Air conditioner electric current be less than or equal to frequency limit current value range.

Determine, to meet power demand, so as to reach air-conditioning peak load shifting effect, to improve electricity consumption to compressor frequency adjust automatically
The reliability that equipment uses.
Further, referring to Fig. 2, it is based on the air condition of that present invention control method first embodiment, in the air condition of that present invention control
In method second embodiment processed, the air-conditioner control method further include:
Step S50 receives predetermined server and is restricted driving by internet to the level of power consumption that the air-conditioning in preset regions is sent
Instruction.
In the present embodiment, above-mentioned predetermined server can be a total server, coupled multiple for managing
The work of air-conditioning.Specifically, which can be connect with multiple air conditioners by internet, and each air-conditioning is powering on
When, current working condition can be reported, to server to facilitate server to be checked and be managed.The server can be set
It sets in power supply bureau, the operation of air conditioner in its power supply area is managed collectively by power supply bureau.For example, user can be in the service
It is operated on device, the selected cell or air-conditioning for needing to carry out power consumption restriction, then unifying will be upper by way of internet
It states level of power consumption restricted driving instruction and is sent to each air-conditioning, limited with the power consumption to air-conditioning.
Further, referring to Fig. 3, it is based on the air condition of that present invention control method first embodiment, in the air condition of that present invention control

So that the complete machine current value is less than or equal to the frequency limit current value.
6. air conditioner controlling device as claimed in claim 5, which is characterized in that described first, which obtains module, includes:
First acquisition unit reduces ratio for obtaining preset grade in the level of power consumption restricted driving instruction;
Computing unit, for calculating standard operating current according to the preset standard power consumption of air-conditioning and voltage rating, and according to described
Standard operating current and grade reduce ratio and calculate the frequency limit current value.
7. air conditioner controlling device as claimed in claim 5, which is characterized in that the adjustment module includes:
Adjustment unit, for when the current complete machine current value be greater than the frequency limit current value when, according to preset compressor
The frequency parameter that downgrades reduces the frequency of the compressor;
Second acquisition unit, for after reducing compressor frequency preset time, obtaining the current complete machine electricity of the air-conditioning again
Flow valuve, and judge whether the current complete machine current value obtained again is greater than the frequency limit current value.
8. the air conditioner controlling device as described in any one of claim 5 to 7, which is characterized in that the air conditioner control dress
It sets further include:
Second judgment module, for judging whether the frequency of the compressor is less than predeterminated frequency;
Control module, for it is out of service to control the air-conditioning when the frequency of the compressor is less than predeterminated frequency;
When the frequency of the compressor is more than or equal to predeterminated frequency, triggering the adjustment module reduces the frequency of compressor.
