（2）If the second anti-cold wind-warm syndrome angle value≤Tmin ＜ first of setting set anti-cold wind-warm syndrome angle value, indoor fan is with the
One wind speed setting is operated.
（3）If Tmin ＜ second set anti-cold wind-warm syndrome angle value, indoor fan is shut down.
In anti-cold wind protected mode, according to the difference of Tmin, control indoor fan operated with the first wind speed setting or
Shut down, it is to avoid blow a cold wind over, improve user experience, improve the stability of operation of air conditioner.
In anti-cold wind protected mode, when Tmin >=the first sets anti-cold wind-warm syndrome angle value, then air-conditioning exits anti-cold wind protection
Pattern, normal operation, it is ensured that user normally uses.
In the present embodiment, first to set anti-cold wind-warm syndrome angle value be 36 DEG C, and second to set anti-cold wind-warm syndrome angle value be 16 DEG C,
One wind speed setting is 650 revolutions per seconds, it is to avoid wind speed is excessive to cause user uncomfortable.
Step S7：Air-conditioning enters anti-overtemperature protection pattern.
When there is temperature value more than the first anti-overtemperature value of setting, air-conditioning enters anti-overtemperature protection pattern.
In anti-overtemperature protection pattern, following step is specifically included：

5th speed frequency reducing.
（4）If Tmax >=4th sets anti-overtemperature value, and continues the second setting time, then compressor of air conditioner is shut down.
Wherein, the speed of fourth rate ＜ the 5th.
In anti-overtemperature protection pattern, according to the difference of Tmax, control compressor is dropped with fourth rate frequency reducing, the 5th speed
Frequency is shut down, and to reduce heat exchange temperature, it is to avoid the too high damage of heat exchange temperature, improves the security of heat exchanger, improves empty
Allocate and transport the safety and stability of row, it is ensured that air-conditioning normally runs, it is to avoid air-conditioning is damaged.
In the present embodiment, the second setting time is 2 minutes, has both avoided being shut down late excessively caused by overlong time, is avoided again
Shut down too early caused by time is too short, anti-overtemperature value set in Tmax >=4th, and continue compressor shutdown at 2 minutes,
Compressor mistakenly stop machine is avoided, the stability and reliability of compressor operating is improved, compressor is effectively protected, operation of air conditioner is improved
Safety and stability.
In anti-overtemperature protection pattern, by carrying out frequency reducing or shutdown to compressor, Tmax can be reduced gradually, therefore,
In anti-overtemperature protection pattern, also comprise the steps：
（5）If Tmax≤the first sets anti-overtemperature value, air-conditioning exits anti-overtemperature protection pattern.
In anti-overtemperature protection pattern, when Tmax≤the first sets anti-overtemperature value, air-conditioning exits anti-overtemperature protection mould
Formula, it is to avoid exit enter anti-overtemperature protection pattern caused by anti-overtemperature protection pattern repeatedly in advance, and then avoid entering anti-repeatedly
Operation of air conditioner exception caused by overtemperature protection pattern, improves the stability and security of operation of air conditioner.
In the present embodiment, first to set anti-overtemperature value be 42 DEG C, and second to set anti-overtemperature value be 44 DEG C,
Three to set anti-overtemperature value be 46 DEG C, and the 4th to set anti-overtemperature value be 48 DEG C.
In the present embodiment, fourth rate is 0.2Hz/s, and the 5th speed is 1Hz/s, it is to avoid compressor frequency changes excessive
Caused operation is unstable.
The air conditioning control method of the present embodiment, obtains the temperature value of heat exchanger each stream, when there is temperature value less than the
During one setting antifrost temperature value, air-conditioning enters antifrost protected mode；Anti-cold wind-warm syndrome is set less than first when there is temperature value
