Refer to Fig. 1, there is disclosed a preferred embodiment of the self-cleaning control method of air-conditioner of the present invention, in the present embodiment, the self-cleaning control method of air-conditioner comprises the steps:
S10, air-conditioner detects outdoor environment temperature, and the accumulated running time of the temperature of the inlet and outlet of sensing chamber's external heat exchanger or detection compressor;
Particularly, described accumulated running time is that air-conditioner completes the accumulative running time of last time from clear rear compressor.
S20, the outdoor environment temperature of detection and predetermined outdoor temperature carry out contrasting and judge whether outdoor environment temperature is less than or equal to predetermined outdoor temperature by air-conditioner, and the temperature of the inlet and outlet of the outdoor heat exchanger of detection are carried out contrasting and judge whether the temperature difference of inlet and outlet is less than or equal to predetermined temperature difference and maybe the accumulated running time of the compressor of detection and predetermined running time is carried out contrasting and judge whether accumulated running time is more than or equal to the predetermined running time;
Particularly, predetermined outdoor temperature is set to 35 DEG C, and predetermined temperature difference is set to 5 DEG C, and the predetermined running time is set to 100 hours.Air-conditioner judges whether outdoor environment temperature is less than or equal to 35 DEG C, and judges whether the temperature difference of the inlet and outlet of outdoor heat exchanger is less than or equal to 5 DEG C or judge whether the accumulated running time of compressor is more than or equal to 100 hours.
S30, predetermined outdoor temperature is less than or equal at outdoor environment temperature, and the accumulated running time that the temperature difference of the inlet and outlet of outdoor heat exchanger is less than or equal to predetermined temperature difference or compressor is when being more than or equal to the predetermined running time, air-conditioner enters heating operation and arranges the running frequency of compressor and the rotating speed of outdoor fan with frost solidifying on outdoor heat exchanger;
Particularly, described the running frequency of compressor is set and the rotating speed of outdoor fan is arranged according to the temperature and humidity of outdoor environment, air-conditioner is detecting that outdoor environment temperature is less than or equal to 35 DEG C, and the temperature difference of inlet and outlet of the outdoor heat exchanger detected is less than or equal to 5 DEG C or accumulated running time of compressor of detecting is more than or equal to 100 constantly little, air-conditioner sends cue to remote control end, remote control termination is received the cue of air-conditioner transmission and is sent prompting to make user select cleaning operation, the button of user by selecting remote control end sends operation instruction signal to remote control end, remote control end sends purge signal according to operation instruction signal to air-conditioner, air-conditioner switches to heating operation after receiving the purge signal of remote control end transmission and the running frequency of compressor is set to 120Hz/min and the rotating speed of outdoor fan is set to 0r/min.
S40, air-conditioner switches at refrigeration mode;
Particularly, described air-conditioner switches to refrigeration mode after the heating operation scheduled time, or described air-conditioner will detect that the temperature in the exit of outdoor heat exchanger contrasts with outlet predetermined temperature, be less than outlet predetermined temperature in the temperature in the exit of outdoor heat exchanger and maintain and switch to refrigeration mode after the scheduled time and the rotating speed that outdoor fan is set, in the present embodiment, air-conditioner is switching to heating operation after 10 minutes or after the temperature of outlet outdoor heat exchanger being detected is less than-2 DEG C and maintains 5 minutes, air-conditioner switches to refrigeration mode and the rotating speed of outdoor fan is set to 850r/min to carry out defrost to outdoor heat exchanger fast, thus the condensed water after defrost is cleared up for the dust stratification on outdoor heat exchanger.
In addition, for improving cleaning performance, the self-cleaning control method of air-conditioner of the present invention also detects air-conditioner and switches to the temperature of the inlet and outlet of the number of times of heating operation or sensing chamber's external heat exchanger and judge whether the temperature difference of inlet and outlet is greater than predetermined temperature difference in S40, when the temperature difference that air-conditioner switches to the number of times of heating operation not reach the inlet and outlet of predetermined running number of times or sensing chamber's external heat exchanger is not more than predetermined temperature difference, air-conditioner performs step S30 again after refrigeration mode runs the scheduled time, in the present embodiment, air-conditioner is judging through 5 heating operations or is judging that the temperature difference of inlet and outlet of outdoor heat exchanger stops self-cleaning after being greater than 5 DEG C, that is air-conditioner maintenance refrigeration mode is no longer switched to heating operation, until air-conditioner determines outdoor environment temperature be again less than or equal to predetermined outdoor temperature, and the accumulated running time that the temperature difference of the inlet and outlet of outdoor heat exchanger is less than or equal to predetermined temperature difference or compressor is when being more than or equal to the predetermined running time.
Because the self-cleaning control method of air-conditioner of the present invention is by entering heating operation with frost solidifying on outdoor heat exchanger, then switch to refrigeration mode and defrost is carried out to outdoor heat exchanger, thus the condensed water after defrost is cleared up for the dust stratification on outdoor heat exchanger, this can effectively reduce the dust stratification accumulated on outdoor heat exchanger, so effectively improve air-conditioner heat transfer effect, reduce energy consumption.
