Air conditioning unit and control device used for cleaning air conditioning unit

Abstract

The invention relates to an air conditioning unit. The air conditioning unit sequentially comprises a draught fan, a primary filter, electrostatic dust collectors and a surface air cooler from an air inlet to an air feeding port. The air conditioning unit is characterized in that a first air valve is arranged between the electrostatic dust collectors and the surface air cooler, and a window and a second air valve are arranged at the portions, between the electrostatic dust collectors and the first air valve, of the wall of a unit box body. By the adoption of the air conditioning unit, dust in the air conditioning unit can be treated without water, the drying step in water method dust removal is omitted, and a work mode and a dust removal mode of the air conditioning unit can be automatically switched. The invention further relates to a control device used for cleaning the air conditioning unit.

Description

【Technical field】 [0001] The present invention relates to air-conditioning equipment, in particular to an air-conditioning unit, and more specifically to an air-conditioning unit with automatic cleaning function and a control device for the air-conditioning unit. 【Background technique】 [0002] The most basic functional sections of a conventional air-conditioning unit include an initial effect mixing section, a surface cooling section, and a fan section. The primary filter section can handle larger solid particles, but has no effect on fine particles, especially PM2.5. At present, the main treatment technologies for fine .5 particulate pollution mainly include HEPA filtration and electrostatic dust removal. However, the HEPA filter has high resistance and is not suitable for air conditioning units; electrostatic dust removal produces ozone, which affects air quality, and it is inconvenient to disassemble and clean. [0003] Electrostatic dust removal has been applied in ai...

AI Technical Summary

Problems solved by technology

The efficiency of this electrostatic dust removal method is low, and a medium-efficiency filter needs to be installed afterwards, which increases the resistance of the equipment and increases the energy consumption of the fan; the ozone generated by the electrostatic precipitator directly enters the room, posing a threat to air quality and human health; when cleaning The spray pipe sprays water directly to the dust collector of the electrostatic precipitator. After cleaning, there is water in the electrostatic precipitator, and it needs to wait for it to dry before starting up.
