in the high-efficiency filter screen regeneration mode, a fresh air pipe is opened, a circulating fan is turned upside down, and desorption objects are sucked into an outdoor unit and then discharged from the fresh air pipe.
In a preferred embodiment, the efficient filter regeneration mode further includes: the used purification layer is rolled up through the scroll, and meanwhile, the unused purification layer is unfolded, so that the maintenance times of the purification layer are reduced, the overall service life of the high-efficiency filter screen is prolonged, and the maintenance-free duration effect of the high-efficiency filter screen is improved.
More preferably, after the high-efficiency filter screen regeneration mode, the circulating fan and the fresh air pipe are closed in a delayed manner so as to ensure that the desorbed substances are completely discharged.
In a preferred embodiment, before the high-efficiency filter screen regeneration mode is performed, whether the high-efficiency filter screen needs to be self-cleaned is judged by detecting the front-rear air pressure difference of the high-efficiency filter screen, and only when the air pressure difference is higher than a preset value, the high-efficiency filter screen regeneration is performed.
According to experimental simulation, the regeneration mode of the efficient filter screen can prolong the service life of the efficient filter screen by more than 3 times under the same filter effect, and long-term maintenance-free of the efficient filter screen is realized.
