When device is the fixed frequency air conditioner of specific model, the first preset duration can be 10min.
Compressor is with the concrete condition of the first preset duration of maximum running frequency stable operation permitted under current working
Can be：Convertible frequency air-conditioner start after run preceding first preset duration, convertible frequency air-conditioner under other states according to setting most
High running frequency runs the first preset duration, the first preset duration of fixed frequency air conditioner stable operation.
In some embodiments of the invention, parameter phase of the above-mentioned fiducial temperature threshold value with air-conditioning device under current working
Matching, the parameter include the outdoor temperature of outdoor environment residing for operational mode, air-conditioning device and the room of residing indoor environment
Interior temperature.
Further, when air-conditioning device is run with heating mode, the average value of outdoor temperature and indoor temperature is bigger, in advance
If temperature difference threshold is smaller, when air-conditioning device is run in a chiller mode, the average value of outdoor temperature and indoor temperature is bigger, presets
Temperature difference threshold is bigger.

Calculate and judge whether the absolute value of the difference between the two is more than or equal to fiducial temperature threshold value, if so, the operation of judgement air-conditioning device
State is normal, if it is not, the running frequency of compressor then is promoted 1 hertz, after stable operation 10s again, obtains air outlet temperature again
Degree and intake air temperature, and calculate and judge whether the absolute value of the difference between the two is more than or equal to fiducial temperature threshold value, if so, sentencing
The operating status for determining air-conditioning device is normal, if it is not, the running frequency of compressor is then promoted 1 hertz, after stable operation 10s again,
Air outlet temperature and intake air temperature are obtained again, and calculate and judge whether the absolute value of the difference between the two is more than or equal to default temperature
Poor threshold value, if so, the operating status of judgement air-conditioning device is normal, if it is not, then judging that the operating status of air-conditioning device is abnormal, i.e.,
Coolant quantity missing or insufficient in the refrigeration system of air-conditioning device.
In some embodiments of the invention, after the operating status exception for judging air-conditioning device, method of the invention is also
Including：Exception information is sent to the display panel of air-conditioning device, to provide prompt message of the air-conditioning device there are failure, so as to
Air-conditioning device is repaired convenient for user.
