Abstract
According to the problem of insufficient capacity in the central exhaust system of residential kitchen in high-rise buildings, this paper analyzes the reason for the difficulties of the flue exhaust on the basis of field tests on a manufacturer’s 33-layer central exhaust system. According to the field test data of 33-layer flue, the CFD technology was applied to simulate the velocity and pressure field distribution on different cross-sectional size of exhaust pipe. In guaranteed the exhaust effect of the most unfavorable loop flue, the paper contrasts and analyzes the flue exhaust effect of a variety of different cross-sectional dimensions, thus to simulate reasonable cross-sectional area of smoke shaft for each floor. This simulation results play an important reference role for the formulation of concentrated exhaust system construction of the new residential kitchen standard atlas of Shaanxi province.
