Step S303, if heating mode, when indoor temperature and the temperature difference of design temperature are equal to the 4th predetermined temperature value
When, target frequency is the rated frequency of air-conditioning and the product of a predetermined threshold, if indoor temperature and the temperature difference of design temperature are less than
During equal to five predetermined temperatures, target frequency is the peak frequency of air-conditioning work and the product of a predetermined threshold.
When it is implemented, the 3rd predetermined temperature, the 4th predetermined temperature and the 5th predetermined temperature can also be selected as needed
Select.3rd predetermined temperature is 0.5 DEG C, and the 4th predetermined temperature is -0.5 DEG C, when the 5th predetermined temperature is -1.0 DEG C, and current air-conditioning
Rated frequency be 53Hz, maximum operation frequency is 80 Hz, predetermined threshold 0.6, for example, the calculation of target frequency is such as
Under：
1) during refrigeration mode：
A. during indoor temperature-design temperature=0 DEG C, outdoor target frequency is 53*0.6=31Hz;
B. indoor temperature-design temperature>At=0.5 DEG C, outdoor target frequency is 80Hz;
2) during heating mode：
A. during indoor temperature-design temperature=- 0.5 DEG C, outdoor target frequency is 53*0.6=31Hz;
B. indoor temperature-design temperature<At=- 1.0 DEG C, outdoor target frequency is 80*0.6=48Hz.
In further embodiment, wherein step S200 China and foreign countries circumstance temperature degree specifically includes in the range of fiducial temperature：
If step S201, current air-conditioning is refrigeration mode, judge whether outer shroud temperature meets more than 25 DEG C, less than the 6th
Predetermined temperature value；
If step S202, current air-conditioning is heating mode, judge whether outer shroud temperature meets less than 15 DEG C, more than the 7th
Predetermined temperature value.
When it is implemented, the 6th predetermined temperature value and the 7th predetermined temperature value can be also configured according to the needs of user.
Preferably, the 6th predetermined temperature value is arranged to 43 DEG C, and the 7th predetermined temperature value may be configured as 5 DEG C.Therefore, outer shroud under refrigeration mode
Temperature meets 25 DEG C<Outer shroud temperature<43 DEG C, heating outer shroud temperature meets：5℃<Outer shroud temperature<15℃.
Specifically, further included after the step S700：
If step S710, quickly starting compressor failure, with predetermined frequency after air-conditioner outdoor unit one scheduled time of shutdown
Rate restarts compressor, if will be started failure information with preset frequency restarting compressor failure twice in succession and be sent to
Indoor unit.
When it is implemented, if high frequency, which starts, driving malfunction occurs, driving malfunction information is not issued room by outdoor master control
Interior, outdoor shutdown is pressed common mode after 3 minutes and is started once again, if common twice in succession again start failure, by event
Barrier issues interior.
Wherein common mode starts specifically, first turn on charge mode, from frequency 0Hz, using climbing speed as 1Hz/s,
30Hz is risen to, then using climbing speed as 1Hz/s, rises to 55Hz, is stopped 1 minute in this frequency；Again with climbing speed
For 1Hz/s, 75Hz is risen to, is stopped 1 minute in this frequency, it is last toward the operation of maximum target frequency.
