Description

Technical Field

[0001] The invention relates to the technical field of air circulation, and in particular to an intelligent circulating wind building system. Background Art

[0002] As people's living standards continue to improve, they have high requirements for the home environment, so they will install fresh air systems at home to provide comfortable and fresh air indoors. The fresh air system can purify the fresh air indoors and introduce it into bedrooms, living rooms and other areas that need fresh air, while discharging the dirty air indoors to the outside.

[0003] Traditional fresh air systems need to filter the incoming external air during air circulation. The filtration will produce a large amount of impurities attached to the filter net, which needs to be disassembled and cleaned regularly. The disassembly and cleaning process is cumbersome, time-consuming and labor-intensive. In addition, the fresh air system directly diverts the air to various spaces in the room after filtering, resulting in untreated air entering the room after filtration, causing indoor air pollution, thereby affecting the indoor air quality. At the same time, since the existing fresh air system diverts the air through its own operation, the wind flow in various spaces in the room cannot be changed, resulting in slower air circulation in spaces far away from the fresh air system. It can only be changed by changing the size of the delivery pipe, which has little effect and a low diversion effect. For this reason, we propose an intelligent circulating air building system.
