Description
Technical field
The present invention relates to air conditioners to set field, in particular to a kind of method that air conditioner is continuously run.
Background technique
In inverter air conditioner product, various protection functions are all set.Some air conditioners have frequency conversion circuit guarantor
Shield stops function.This is because the power supply in user has excessive surge superposition, as a result cause frequency conversion circuit immediate current excessive,
It is mainly shown as that primary current immediate current is excessive.In order to protect frequency conversion circuit component not to be damaged, therefore suspend the fortune of air conditioner
Turn, referred to as protection stops.Protection stops if recurring 5 times, and air conditioner shuts down and alarms, and manual intervention is waited to carry out
It reruns.Manual intervention is rerunned exactly: being cut off the power supply of air conditioner, is then accessed power supply again, resets air conditioner fortune
Turn.The power issue of user has following possible:
1, interference print adds on power supply;
2, it is struck by lightning;
3, supply voltage is high (specified: 220V supply voltage up to 300V or so).
Summary of the invention
The object of the present invention is to provide a kind of methods that air conditioner is continuously run, by changing maximum primary current value and frequency
It is not impaired simultaneously to ensure that in air conditioner frequency conversion circuit component for rate, so that air conditioner is continuously run, to allow user's normal use
Air conditioner.
In order to achieve the goal above, the present invention is achieved by the following technical solutions:
A kind of method that air conditioner is continuously run, its main feature is that, this method comprises the following steps:
S1, when the stopping of frequency conversion loop protection occurs for air conditioner, the primary current value and frequency when protection stops occur for record
Value;
S2 reduces the setting value of maximum the primary current value and maximum frequency values of air conditioner;
S3, judges whether air conditioner occurs frequency conversion loop protection in T time and stop, if so, S2 is thened follow the steps, if
It is no, then follow the steps S4;
S4 improves the setting value of maximum the primary current value and maximum frequency values of air conditioner.
The step S2 specifically: the maximum primary current value and maximum frequency values of air conditioner are set, so that maximum one
Primary current value and maximum frequency values are no more than primary current value and maximum frequency values when last time generation protection stops.
Also include after the step S2: the step for air conditioner is restarted after preset time threshold.
The maximum primary current value and maximum frequency values of air conditioner drop in the step S2 fix value until.
The air conditioner maximum primary current value and maximum frequency values drop to fix value until after, if air-conditioning
Machine, which recurs frequency conversion loop protection in the value that fixes, to be stopped, and the air conditioner shuts down and alarms.
The maximum primary current value of air conditioner and the setting value of maximum frequency values are increased to air conditioner in the step S4
Until maximum primary current value and maximum frequency values initially set.
Compared with prior art, the present invention having the advantage that
This method ensure that frequency conversion circuit component is not impaired same in air conditioner by changing maximum primary current value and frequency
When, so that air conditioner is continuously run, to allow user's normal use air conditioner.

Specific embodiment
The present invention is further elaborated by the way that a preferable specific embodiment is described in detail below in conjunction with attached drawing.
Fig. 1 is the circuit diagram in frequency changer circuit, which includes supply voltage diode, the inductance of circuit connection
Coil L, triode Q, capacitor C, power amplifier and air conditioner motor MC, when supply voltage has external superposition interference, primary electricity
Stream can also increase (referring to fig. 2) moment.The present invention provides the methods (referring to Fig. 3) that air conditioner is continuously run thus, by changing
Become primary current, specifically include the following steps:
S1, when the stopping of frequency conversion loop protection occurs for air conditioner, primary current value when protection stops occurs for memory record
And frequency values;
S2 reduces the setting value of maximum the primary current value and maximum frequency values of air conditioner;For the protection function of air conditioner
The setting value of energy, is to be set by the protection value of frequency changer circuit component, the setting value to the air conditioner of a certain model is
Certain.Such as a certain type sets protective current value as 50A, i.e., carries out protection when current value reaches 50A and stop, such as Fig. 4
Shown, in the case where identical external disturbance, in different frequencies, primary current waveform.Illustrate frequency values and one
After primary current value reduces, the current value of moment can also be reduced, and such as not arrive protective current value, and protection would not occur and shut down.
In a particular embodiment, step S2 is the maximum primary current value and maximum frequency values for setting air conditioner, so that most
Primary current value and maximum frequency values when big primary current value and maximum frequency values stop no more than last time generation protection, and
Air conditioner is restarted after preset time threshold.For example, it is 13.5A, frequency that primary current value when protection stops, which occurs, for last time
Rate value is 80Hz, when restarting after 3min, set maximum primary current value as 13.4A, maximum frequency values 79Hz.
S3, judges whether air conditioner occurs frequency conversion loop protection in T time and stop, if so, S2 is thened follow the steps, if
It is no, then follow the steps S4;
S4 improves the setting value of maximum the primary current value and maximum frequency values of air conditioner.
As shown in figure 5, the maximum primary current value and maximum frequency values of air conditioner drop to and fix in above-mentioned step S2
Until value.In addition, the air conditioner maximum primary current value and maximum frequency values drop to fix value until after, if
Air conditioner, which recurs frequency conversion loop protection in the value that fixes, to be stopped, which shuts down and alarm.
As shown in fig. 6, the maximum primary current value of air conditioner and the setting value of maximum frequency values mention in above-mentioned step S4
Until height to air conditioner maximum primary current value initially set and maximum frequency values.
In conclusion a kind of method that air conditioner is continuously run of the present invention, by changing maximum primary current value and frequency,
It ensure that frequency conversion circuit component is not impaired simultaneously in air conditioner, so that air conditioner is continuously run, to make user's normal use empty
Tune machine.
It is discussed in detail although the contents of the present invention have passed through above preferred embodiment, but it should be appreciated that above-mentioned
