Roof fan selection strategy for residential composite power flue system based on exhaust demand
摘要
Abstract
The residential kitchen exhaust system can solve the problems of excessive static pressure of the flue and insufficient exhaust air volume of the user through the roof fan.The calculation model of the residential composite dynamic flue system was constructed,the roof fan selection design was carried out with the goal of ensuring the exhaust air volume of the user,and the roof fan selection of the 6～35 layer flue system was studied.The results show that there is an obvious linear relationship between the flue main pipe flow velocity and the rated pressure or the rated air volume amplification coefficient of the roof fan in the selection calculation,and the selection and estimation method based on the flue flow rate and the roof fan selection strategy of the residential composite dynamic flue system based on exhaust air demand are proposed.The selected roof fan can effectively increase the exhaust air volume of the flue,reduce the static pressure of the flue,and facilitate the control of pollutants.The results indicates that the flue area should be enlarged appropriately to reduce the fan selection,which is more conducive to the energy saving of the exhaust system.关键词
