摘要
住宅建筑的厨房对居住环境造成较大的污染,历来是居室通风设计中的重点。当前,随着让人们生活水平的提高自我保健意识的增强以及环保意识的要求,有效而迅速的排除受污染的空气是改善居室通风质量的重要保证。大量的调查研究结果都说明在高层住宅中普遍使用的集中式排烟烟道还存在许多的不足期待改进。论文在理论分析的基础上,运用计算机数值模拟的方法,选取典型的30层高层住宅厨房集中排烟道模型模拟分析排烟道排风质量,分析排风量不足、不平衡的原因,并针对解决的思路及方法进行探讨。对其原始工况和利用奇偶数楼层分别采用风道排风的方法增加支管间距后的工况进行模拟,并对两种工况排风效果进行对比分析,通过对模拟结果及理论分析的总结探讨在工程实践中可行的改进方法。建议可以通过设计双风道奇偶数楼层分开排风法达到增加排风道面积加长支管间距的目的,有效的改善排风效果。建议暖通设计师积极参与通风道设计及计算工作,系统的设计集中排风道,以达到良好的排风效果。
Residential buildings in the kitchen to the living environment which causes greater pollution, has always been the focus of the design room ventilation. At present, with the improvement of living standards so that people＇s awareness of self-care, as well as awareness of environmental protection requirements, effective and prompt exclusion of contaminated air is to improve the quality of an important guarantee for room ventilation. A lot of investigation and research results indicate the widespread use of high-rise apartment in the centralized exhaust flue there are still many deficiencies in looking forward to improvements. Papers in the theoretical basis of the analysis, using computer numerical simulation method, select a typical 30-storey high-rise residential kitchen which exhausts channel model simulation analysis focused on Exhaust ventilation quality, and analysis of ventilation insufficient, unbalanced causes and address the ideas and methods were discussed. To its original condition and use of odd-even number of floors are used duct exhaust branch pipe spacing of the ways to increase after the simulation conditions, and two kinds of working conditions exhaust effects comparative analysis of simulation results and theoretical analysis of the summary to explore feasible in engineering practice, improved method. Proposals could wind through the design of pairs of even-numbered floors Dodge separate exhaust ventilation Road area of France to increase the longer the purpose of branch pipe spacing and effective to improve the ventilation effect. HVAC designers to actively participate in the proposed design and calculation of ventilation Road work, system design focused on exhaust channel to achieve good ventilation effect.
