Dust extraction control method, dust extraction control device and air-conditioner

Abstract

The invention provides a running control method, a running control device and an air-conditioner. The running control method is suitable for outdoor draught fan assemblies of the air-conditioner; the running control method includes the steps that working condition environment records and running parameter records of the outdoor draught fan assemblies under the power-on state are determined; corresponding dust extraction periods are determined according to the working condition environment records and the running parameter records; within one dust extraction period, the outdoor draught fan assemblies are controlled to reversely rotate and run. According to the technical scheme, on one hand, the possibility of not-clean dust extraction caused by the too short dust extraction period is reduced; on the other hand, the possibility of too high power dissipation caused by too long dust extraction period is reduced, under the normal using condition of the air-conditioner, efficient dust extraction on the outdoor draught fan assemblies can be automatically carried out, the running efficiency of an outdoor heat exchanger is optimized, and the economic cost and the time cost of manual dust extraction are reduced.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to an operation control method, an operation control device and an air conditioner. Background technique [0002] The outdoor unit of the air conditioner is generally located in an outdoor environment with poor air quality. Long-term use will easily cause a large amount of dust to accumulate on the outdoor heat exchanger, which will affect the heat exchange efficiency of the outdoor heat exchanger. [0003] In the related technology, manual dust removal or controlling the air conditioner to stop working for fixed-time fan reversal dust removal have the following technical defects: [0004] (1) Manual dust removal will result in higher labor maintenance costs; [0005] (2) For an air conditioner that only includes a single outdoor fan, when the outdoor fan of the air conditioner is reversed to remove dust, the air conditioner cannot perform normal operations such as...

AI Technical Summary

Problems solved by technology

[0004] (1) Manual dust removal will result in higher labor maintenance costs;

[0005] (2) For an air conditioner that only includes a single outdoor fan, when the outdoor fan of the air conditioner is reversed to remove dust, the air conditioner cannot perform normal operations such as heating or cooling, which affects the user experience;

[0006] (3) Preset and fixed duration fan reversal dust removal is not suitable for changes in the air environment. For example, the dust index data shows that the PM index is lower than 50. At this time, there are few dust particles and are not easy to accumulate, so frequent dust removal is not required. However, when the dust index data shows that the PM index is higher than 300, there are many dust particles and they are easy to accumulate, so frequent dust removal is required, that is, setting a fixed time will not only affect the normal operation of the air conditioner but also cause unnecessary work loss
