Abstract
The invention discloses a filter self-cleaning system. A filter is arranged in a filter box. The system comprises a spray washing device and a cleaning water tank. The spray washing device is arranged on at least one side of the filter, and the spray washing device and the cleaning water tank are communicated. The filter self-cleaning system provided in the invention can perform automatic cleaning on the filter of a combined air-conditioning unit and monitor the resistance change of the filter in real time. When the resistance loss caused by the filter reaches a set value, the dust deposition amount of the filter reaches a degree needing cleaning, then the self-cleaning system can complete washing of the filter. Therefore, the resistance loss caused by filter dust deposits is reduced, the operating efficiency of the air-conditioning unit is improved, and the architectural indoor air quality is guaranteed.
