Problems solved by technology
[0002] Due to the presence of a lot of dust in the outdoor environment, after the air conditioner has been running for a period of time, a large amount of dust will accumulate on its outdoor heat exchanger, which will cause the heat transfer performance of the outdoor heat exchanger to deteriorate, which in turn will lead to a decrease in the capacity of the air conditioner. decrease, increase in energy consumption

Embodiment Construction
[0016] The technical scheme of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific examples, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention .
[0017] see figure 1 , which discloses a preferred embodiment of the self-cleaning control method of the air conditioner of the present invention, in this embodiment, the self-cleaning control method of the air conditioner includes the following steps:
[0018] S10, the air conditioner detects the outdoor ambient temperature, and detects the temperature at the inlet and outlet of the outdoor heat exchanger or detects the cumulative running time of the compressor;
[0019] Specifically, the accumulated running time is the accumulated running time of the compressor after the air conditioner completed the last self-cleaning.
[0020] S20, the air cond...

The invention discloses a self-cleaning control method for air conditioners. The self-cleaning control method includes enabling the air conditioners to detect outdoor environmental temperatures, detecting the temperatures of inlets and outlets of outdoor heat exchangers or detecting the cumulative run time of compressors; enabling the air conditioners to carry out heating running to allow frost to condense on the outdoor heat exchangers when the outdoor environmental temperatures are lower than or equal to preset outdoor temperatures and temperature difference between the inlets and the outlets of the outdoor heat exchangers is lower than or equal to preset temperature difference or the cumulative run time of the compressors is longer than or equal to preset run time; switching the air conditioners into a refrigerating mode. The self-cleaning control method for the air conditioners has the advantages that the air conditioners carry out heating running to allow the frost to condense on the outdoor heat exchangers and then are switched into the refrigerating mode to defrost the outdoor heat exchangers, accordingly, dust accumulated on the outdoor heat exchangers can be cleaned by condensed water generated after the outdoor heat exchangers are defrosted and can be effectively reduced, heat exchange effects of the air conditioners can be effectively improved, and energy consumption can be reduced.
Description
technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to a self-cleaning control method of an air conditioner. Background technique [0002] Due to the presence of a lot of dust in the outdoor environment, after the air conditioner has been running for a period of time, a large amount of dust will accumulate on its outdoor heat exchanger, which will cause the heat transfer performance of the outdoor heat exchanger to deteriorate, which in turn will lead to a decrease in the capacity of the air conditioner. decrease, and energy consumption increases. Contents of the invention [0003] The object of the present invention is to provide a self-cleaning control method of an air conditioner, aiming at reducing the dust accumulation on the outdoor heat exchanger of the air conditioner, improving the heat exchange capacity of the air conditioner, and reducing energy consumption. [0004] In order to achieve the purpose ...
