Filter self-cleaning system

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.

Description

technical field [0001] The invention relates to the technical field of ventilation and air conditioning, in particular to a filter self-cleaning system. Background technique [0002] At present, the air-conditioning units of the central air-conditioning system are equipped with filters, mainly to reduce the impact of indoor and outdoor air pollution on indoor air quality and human health. During use, dust particles in the air are adsorbed on the filter screen, which inevitably It will cause the filter to be clogged, increase the resistance of the airflow, and affect the operating efficiency of the fan. In severe cases, the pressure head of the fan will be insufficient, and the air supply volume cannot meet the design requirements. operating conditions. [0003] However, in the actual use process, some construction units have ignored the issue of convenient maintenance, and when operators maintain and manage air-conditioning units, they only consider how to facilitate and pr...

[0002] At present, the air-conditioning units of the central air-conditioning system are equipped with filters, mainly to reduce the impact of indoor and outdoor air pollution on indoor air quality and human health. During use, dust particles in the air are adsorbed on the filter screen, which inevitably It will cause the filter to be clogged, increase the resistance of the airflow, and affect the operating efficiency of the fan. In severe cases, the pressure head of the fan will be insufficient, and the air supply volume cannot meet the design requirements. operating conditions

[0003] However, in the actual use process, some construction units have ignored the issue of convenient maintenance, and when operators maintain and manage air-conditioning units, they only consider how to facilitate and prolong the single running time of air-conditioning units, sometimes in order to eliminate filter cleaning and replacement. If the filter is removed, the dust will be adsorbed in the heat exchanger of the air conditioning unit after the unit has been running for a certain period of time, resulting in a decrease in the efficiency of the heat exchange equipment.
