Fresh air ventilation device with self-cleaning and dust-removing function and dust-removing method thereof

Abstract

The invention relates to the field of ventilation, and discloses a fresh air ventilating device with a self cleaning and dedusting function. The fresh air ventilating device comprises an execution unit, a detection unit, a controller and an air source unit, wherein the detection unit is used for converting the environment quantity related to self cleaning and dedusting and the working state physical quantity of a system component into electric quantity and conditioning the electric quantity into an electric quantity signal which is compatible with the controller for being transmitted to the controller; the execution unit refers to execution components related to the self cleaning and dedusting, a driving circuit and a driving mechanism of the execution components, the execution unit is mainly used for enabling all execution components to work cooperatively according to an operation result of a control strategy under the regulation action of the controller and realizing the self cleaning and dedusting function on a filter screen; the controller is a microprocessor and has the main functions of collecting and processing the environment quantity and the system work state information of the detection unit at regular times, carrying out operation evaluation on a trend and a result of a dust accumulation process of the filter screen according to a dedusting strategy and outputting different dedusting control modes to filter screen dust accumulation situations in different degrees or different types. The invention also discloses a self cleaning and dedusting method using the fresh air ventilating device. The fresh air ventilating device and the self cleaning and dedusting method, disclosed by the invention, have the advantages that in-time and efficient dedusting can be carried out, and the energy source is saved.

Description

technical field [0001] The invention relates to the field of ventilation, in particular to a fresh air ventilation device and a dust removal method capable of intelligently controlling the whole process of a filter screen to perform self-cleaning and dust removal through scanning. Background technique [0002] With the rapid development of the social economy and the communication industry, a large number of communication base stations have been built and put into operation, and the energy consumption and energy saving of air conditioners in computer rooms have attracted widespread attention from the whole society. In order to respond to the national energy saving and emission reduction policy and reduce the operating cost of communication base stations, a large number of newly built or renovated base stations have begun to use intelligent fresh air energy-saving systems to enable convection and heat exchange between the inside and outside air of the base station, so as to ach...
