摘要
针对高层住宅厨房排气系统排气不均匀的问题,提出解决措施,运用CFD技术对此措施的成效进行了数值模拟,并对模拟结果进行了分析,结果表明:住户分区选用不同性能的吸油烟机后,排气系统各住户的排气均匀性有很大的提高。对于12层住宅,当吸油烟机的同时使用系数取0.66时,分区后系统的平均排气量较未分区提高了9.2%,最大与最小排气量的差值降低了81.6%。
A solution was proposed on enhancing central exhaust system of exhaust uniformity for High-rise residential kitchen, the effectiveness was analyzed contrastively by CFD technology. Based on the example calculation of 12-storey residential, it is indicated that households' exhaust uniformity had greatly improved, when households choosing different performance of range hoods by zone. After households choosing different performance of range hoods by zone (0.66 of simultaneous coefficient), the average exhaust volume for all households of this system had risen 9.2% ,the difference between the maximum and minimum exhaust volume was reduced 81.6%.
