摘要
目的探讨通过在灶台上(排油烟机的正下方)增设补风口对厨房排油烟系统进行补风的方式平衡室内空气,消除传统系统弊端,探求住宅厨房合理的气流组织形式.方法运用CFD-fluent 6.2模拟软件对住宅厨房排油烟系统在无补风和有补风情况下进行模拟研究,分析住宅厨房传统排油烟系统存在的污染室内空气、增加暖通空调系统能耗等问题,分析不同工况下厨房室内气流速度分布,压力分布.结果设置大小为0.06～0.10 m2的补风口时,补风量为0.162～0.184 kg/s,能有效地避免油烟等污染物外溢,降低运行能耗.结论增设补风后厨房仍维持负压状态,在压差作用下将室外新风吸进厨房达到了自然补风的效果,排油烟机处能形成合理地气流组织,满足排风要求,有效地排出污浊气体.
The paper discusses how to making up air to balance indoor air and eliminate the traditional sys- tem defects, through in the hearth（ under the smoke exhaust ventilator）additional secondary air tuyere. Using the CFD-fluent 6.2 simulation software, we simulate the airflow organization of the kitchen exhaust system if making up air. The paper analyzes the kitchen indoor airflow velocity distribution, and the pressure distribu- tion in the different condition. Setting sizes for 0. 06 -0. 10 m2 of secondary air tuyere,fill with air 0. 162 - 0. 184 kg/s, it can avoid lampblack pollutants spilling effectively ,reduce the operating energy consumption. After making-up air the kitchen remains negative state, under the action of differential pressure, outdoor air is sucked into the kitchen so as to achieve the result, form reasonably airflow organization, meet exhaust requirements, get rid of foul gas effectively.
