大型商用厨房是一个复杂的高温高湿环境。在夏季若未采用有效的室外新风补给措施，则需要给厨房提供大量空调冷风以满足排烟需求，造成大量的能耗。本文提出一种大型中餐厨房布局，并基于分析软件FLUENT进行数值模拟，采用PMV-PPD预测模型对4种不同比例的送风情况进行热舒适性评价。结果表明，对于这种厨房布局，采用20％冷风比例的组合气幕通风方式，不仅能防止污染物逸出、降低厨房所需空调冷风风量，减少能耗，同时可获得满意的热舒适性环境。

A large commercial kitchen is a complicated environment with high temperature and high humidity.If there’s no effective fresh air supply system,a large amount of cold air is needed to satisfy the requirement of emission,with plenty of e-lectric energy is wasted.In this paper,a large Chinese kitchen is introduced based on the analysis software FLUENT.The PMV-PPD model is adopted to evaluate the thermal comfort of 4 conditions with different air apply ratios.The result show that for this kind of chicken layout,pollutants will be controlled,when the cold air apply ratio is 20%,with the volume of the cold air reduced and energy-saving.The requirement of the thermal comfort will also be met.
