Fresh air system and louver of fresh air system

Abstract

The invention relates to a fresh air system and a louver of the fresh air system. The louver of the fresh air system comprises a frame and at least one fixing assembly fixed in the frame; each fixing assembly comprises fixing pieces and fixing grooves, the fixing pieces and the fixing grooves are identical in number and are sequentially and alternately arranged in the height direction, the section of each fixing groove is of a U-shaped structure, an opening of each fixing groove faces upwards, the fixing pieces are positioned above the openings of the fixing grooves, and a flow channel is formed between the fixing pieces and the fixing grooves; the distance between the lower end of each fixing piece and the groove bottom of the fixing groove located on the adjacent lower side is a first distance, and the first distance is not larger than the height of the side walls of the two sides of each fixing groove. The louver of the fresh air system can effectively achieve the dustproof and waterproof effects, the situation that equipment or a pipeline is corroded by rainwater is avoided, the service life is guaranteed, meanwhile, the internal cleanliness of the fresh air system is guaranteed, the structure is simple, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of ventilation and air conditioning, in particular to a fresh air system and shutters of the fresh air system. Background technique [0002] For industrial and civil buildings with high wind speed, the rain-proof shutters of the conventional fresh air system cannot guarantee sufficient shelter from rainwater, and the rainwater will flow into the house or the air duct, causing corrosion of equipment or pipes, so that some buildings are installed on the fresh air shutters. Add rain-proof elbows, so that not only the structure is complicated, the process is increased, but also the cost is increased. [0003] Therefore, how to provide a louver for the fresh air system that can fully block rainwater, avoid rainwater causing corrosion to equipment or pipelines, ensure service life, simplify the overall structure, and reduce costs is what those skilled in the art need to solve. technical problems.
