主 题：evaluation index system analytic hierarchy process comprehensive performance exhaust hood computational fluid dynamics
摘 要：Indicators are the basis for judging the working performance of exhaust hood and capture performance are usually used as the only *** evaluation index system including three factors of cooking oil fumes(COF)instantaneous capture,health risk impact and thermal comfort was proposed to assess the comprehensive performance of exhaust hood in the present *** primary capture efficiency(PCE)of formaldehyde,the PCE of particulate matter with the diameter less than or equal to 2.5μm(PM_(2.5)),the incremental lifetime cancer risk(ILCR)of formaldehyde,the ILCR of PM_(2.5)and the predicted mean vote(PMV),which can all be quantified with the aid of computational fluid dynamics(CFD),were selected as the *** the analytic hierarchy process(AHP)method was introduced to perform the comprehensive performance evaluation of exhaust *** performance of two exhaust hood structures(grille and orifice type)with three exhaust rates(3000,4000,and 5000 m^(3)/h)in two cooking zones of a university canteen kitchen were *** result showed that the reduction of ILCR of COF exposure is the most important to the performance of exhaust *** comprehensive performance of orifice exhaust hood with exhaust rate of 4000 and 5000 m^(3)/h are optimal;the orifice exhaust hood with exhaust of 3000 m^(3)/h and grille exhaust hood with exhaust rate of 5000 m^(3)/h are moderate;the grille exhaust hood with exhaust rate of 3000 and 4000 m^(3)/h are ***-making priorities based on comprehensive and individual performance are not exactly the same in the two cooking *** is necessary to use the index system to evaluate the comprehensive performance of exhaust hood that considers the impact on human health and thermal comfort.
