Problems solved by technology

[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 conditio

Example Embodiment

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention, but the examples cited are not intended to limit the present invention.

[0022] Such as Figure 1 to Figure 3 As shown, the filter self-cleaning system of the present invention includes a fresh air inlet 1 for introducing air from the outside and a return air outlet 2 for returning some indoor air. The return air duct is used to return some indoor air into the air conditioning box and mix with a small amount of fresh air. After the filter and the heat exchanger are sent into the room, the dust particles in the air will be adsorbed on the filter screen, causing the blockage of the filter 3, increasing the resistance of the airflow, and affecting the operating efficiency of the fan.

[0023] The filter self-cleaning system includes a spray washing device and a was...

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...
