Reference picture 2, in the first embodiment, the control method of the air conditioner include：
Step S10, obtain air conditioner and detect obtained return air temperature and leaving air temp, and calculate the return air temperature with
Temperature difference between the leaving air temp, wherein, difference of the temperature difference between the return air temperature and the leaving air temp
The absolute value of value；
In the present embodiment, return air temperature is detected to obtain by the return air temperature sensor in air conditioner room unit, leaving air temp
Detect to obtain by the leaving air temp sensor in air conditioner room unit.Due in the prior art according to return air temperature with setting temperature
Between difference freezed or heated, this can cause leaving air temp to be subcooled or overheat, and the present embodiment is to air conditioner
Difference between return air temperature and leaving air temp is set, and avoids leaving air temp from bringing the temperature of supercooling or overheat to user
Experience.
Specifically, air conditioner refrigeration or during heating operation, user can be selected comfortable by remote control or line control machine
Air supply pattern, wherein, comfortable air supply pattern refers to enter by the difference between the return air temperature and leaving air temp to air conditioner
Row setting, to realize the control to leaving air temp.When receiving the instruction that user's selection is comfortably blown, the wind deflector of air conditioner

Difference between temperature, and take the absolute value of difference.When obtaining the temperature difference of return air temperature and leaving air temp, C.T is poor
With the magnitude relationship between preset temperature difference.Wherein, preset temperature difference by user according to being actually needed autonomous setting, can be between
Between 1 DEG C to 20 DEG C, the present invention is not specifically limited.It should be noted that preset temperature difference has the deviation model of default value
Enclose, wherein, default value can be 1 DEG C.This is due to that difference between return air temperature and leaving air temp calculates in real time, this
Compressor frequent switching between stopped status and working condition can be caused, in order to avoid state switching caused by return difference, therefore
Default value is set.
Step S20, the magnitude relationship between temperature difference described in comparison and preset temperature difference；

In the present embodiment, the magnitude relationship between C.T difference and preset temperature difference, and sky is adjusted according to magnitude relationship
The operational factor of device is adjusted, wherein, the operational factor of air conditioner can be the frequency of compressor and the rotating speed of indoor fan.Specifically
Ground, when temperature difference is more than preset temperature difference, the frequency of compressor can be reduced, or reduce the rotating speed of indoor fan, this is
Because when temperature difference is larger, leaving air temp can be too high (heating mode) or too low (refrigeration mode), at this moment reduces compressor
Frequency or reduce indoor fan rotating speed, can control air conditioner releive ground air-out.Likewise, it is less than in temperature difference default
During temperature difference, the frequency of compressor can be increased, or the rotating speed of increase indoor fan, this be due to when temperature difference is smaller,
Leaving air temp will not be too high (heating mode) or too low (refrigeration mode), at this moment increases the frequency or indoor fan of compressor
Rotating speed, prevent air conditioner heating (heating mode) or cooling (refrigeration mode) it is excessively slow.It is poor to be equal to preset temperature in temperature difference
When, control compressor shutdown.It should be noted that can also be according to the magnitude relationship between temperature difference and preset temperature difference simultaneously
The rotating speed of compressor frequency or indoor fan is adjusted, so, when temperature difference is more than preset temperature difference, air conditioner can be controlled
More releive ground air-out, when temperature difference is less than preset temperature difference, can accelerate heat up (heating mode) or cooling (freeze mould
Formula), to realize that air conditioner more rapidly reaches, temperature is set.
In the first embodiment, the return air temperature and leaving air temp that air conditioner detects to obtain are obtained first, and are calculated back
Temperature difference between air temperature and leaving air temp, wherein, the temperature difference is between the return air temperature and the leaving air temp
Difference absolute value, the then magnitude relationship between C.T difference and preset temperature difference, in temperature difference not equal to default temperature
When spending poor, according to the magnitude relationship between temperature difference and preset temperature difference, the operational factor of air conditioner is adjusted.So, by right
Difference between the return air temperature and leaving air temp of air conditioner is set, and realizes the control to leaving air temp, so as to avoid
The experience of the temperature of supercooling or overheat is brought to user.

The rotating speed of indoor fan, when temperature difference is more than preset temperature difference, the frequency of compressor and turning for indoor fan can be reduced
Speed, this is due to when temperature difference is larger, and leaving air temp can be too high (heating mode) or too low (refrigeration mode), at this moment reduces
The frequency of compressor and the rotating speed of indoor fan, can control air conditioner more releive ground air-out.It is likewise, small in temperature difference
When preset temperature difference, the frequency of compressor and the rotating speed of indoor fan can be increased, this be due to when temperature difference is smaller,
Leaving air temp will not be too high (heating mode) or too low (refrigeration mode), at this moment increases the frequency and indoor fan of compressor
Rotating speed, it is possible to achieve air conditioner more rapidly reach set temperature.
In a second embodiment, when temperature difference is more than preset temperature difference, reduce the frequency of compressor and reduce interior
The rotating speed of blower fan, when temperature difference is less than preset temperature difference, increases the frequency of compressor and increase the rotating speed of indoor fan.This
Sample, when temperature difference is more than preset temperature difference, control air conditioner more releive ground air-out, temperature difference be less than preset temperature it is poor
When, realize that air conditioner more rapidly reaches and temperature is set.

Step S33, when the temperature difference is more than the preset temperature difference, the frequency of the compressor, or drop are reduced
The rotating speed of the low indoor fan；
Step S34, when the temperature difference is less than the preset temperature difference, the frequency of the compressor, Huo Zhezeng are increased
Add the rotating speed of the indoor fan.
In the present embodiment, when temperature difference is more than preset temperature difference, the frequency of compressor can be reduced, or reduce indoor
The rotating speed of blower fan, this is due to when temperature difference is larger, and leaving air temp can be too high (heating mode) or too low (refrigeration mode),
At this moment reduce compressor frequency or reduce indoor fan rotating speed, can control air conditioner releive ground air-out.Likewise,
When temperature difference is less than preset temperature difference, the frequency of compressor can be increased, or the rotating speed of increase indoor fan, this be due to
When temperature difference is smaller, leaving air temp will not be too high (heating mode) or too low (refrigeration mode), at this moment increases the frequency of compressor
The rotating speed of rate or indoor fan, prevent that air conditioner heating (heating mode) or cooling (refrigeration mode) are excessively slow.
In the third embodiment, when temperature difference is more than preset temperature difference, the frequency or indoor fan of compressor are reduced
Rotating speed, when temperature difference is less than preset temperature difference, increase the frequency of compressor or the rotating speed of indoor fan.So, in temperature
Degree difference is when being more than preset temperature difference, control air conditioner releive air-out, when temperature difference is less than preset temperature difference, realize air conditioner
Rapidly reach and temperature is set.
