Rate is adjusted downward to corresponding minimum frequency.After compressor 4 runs preset third duration according to the minimum frequency, user is reminded
It is handled.It includes sending prompt message to send to user or to scheduled communication center after sale to remind the mode that user is handled
Maintenance request.
Preferably, a length of 90 seconds, preset frequency 8Hz when the interval of third time interval, second radiating mould is run
The process of formula can be that 4 frequency of compressor is lowered 8Hz every 90 seconds, until compressor 4 is run with minimum frequency.
Sub-step S1045, after running second radiating mode and reaching preset second post-set time, acquisition corresponds to
Third tube temperature, until difference between the collected third tube temperature and the initial tube temperature is less than preset 6th threshold
Value.
In embodiments of the present invention, the difference between the collected third tube temperature and the initial tube temperature is less than pre-
If the 6th threshold value after, flow enters sub-step S1046.It should be noted that sub-step S1044 and sub-step S1045 it
Between be coordination.
Sub-step S1046 exits second radiating mode.
In embodiments of the present invention, after exiting the second radiating mode, air conditioner 1 restores normal operation.It should be noted that
There is no inevitable sequencings between sub-step S1041 and sub-step 1044.It is, the air conditioner 1 can same luck
The first radiating mode of row and the second radiating mode can also be to run a corresponding radiating mode as the case may be, enable the
One radiating mode is not interfere with each other with the second radiating mode.
