摘要
利用fluent软件对绍兴市某印染厂染色厂房冬季自然通风进行模拟分析,讨论不同通风口位置、热源强度对其厂房内部的温度和气流分布的影响。结果表明,冬季工况下热源强度达到60℃和80℃时染色工作B区温度高于28℃的区域面积较大,不能满足相关规范要求;通风口高度降低仅在染色1区小面积区域上改善了周围温度和风速,并且导致染色1区和染色2区之间走廊中心区域温度上升以及风速下降;分布密集的染色机周围空间狭窄,风速过低,形成高温区。该厂房冬季自然通风时,北墙尽量少开窗,部分区域可以采用局部通风。
The fluent software was used to simulate and analyze the natural ventilation of the dyeing workshop of a printing and dyeing factory in Shaoxing City in winter, and discuss the influence of different vent positions and heat source intensity on the temperature and airflow distribution inside the workshop. The results show that when the heat source intensity reaches 60℃ and80℃ in winter, the area where the temperature of dyeing work zone B is higher than 28℃ is larger, which cannot meet the requirements of relevant regulations;the height of the vent is only reduced in the small area of dyeing zone 1. The surrounding temperature and wind speed are improved, and the temperature in the central area of the corridor between the dyeing zone 1 and the dyeing zone 2 is increased and the wind speed is reduced;the densely distributed dyeing machine has a narrow space around the dyeing machine, and the wind speed is too low, forming a high temperature zone. When the plant is naturally ventilated in winter,the north wall should have as few windows as possible, and partial ventilation can be adopted in some areas.
