The experimentaS study of residential kitchen gradually expanding oriented structural member exhaust pipe system characteristics

摘要

The purpose of this paper is to study the residential kitchen exhaust pipe system by introducing a gradually expanding oriented structural member called GEOSM for short and analyze the experimental effects of exhaust volume. With the change of the operating rate, we can obtain the best size of the GEOSM. In order to collate and analyze the experimental data, test the experimental effects of the g GEOSM of different sizes. Not only the pressure of main and branch but also the wind speed of the branch is recorded in this paper. In six floors of 400*250 gradually expanding oriented structural member exhaust pipe system, the fan's volume can completely meet the basic requirements of everyday life whether its volume is high-end or low-end. The effect of exhaust is obviously better than the other size of the GEOSM when the cross section width of the GEOSM is 150mm and the cross section length of the GEOSM is 250mm, the height of the GEOSM is 350mm. There arises more smoke down when the cross section width of the GEOSM is 150mm and the cross section length of the GEOSM is 300mm, the height of the GEOSM is 350mm.
