摘要:
针对具有集中热源和集中污染源的工业厂房，热压通风与机械排风共同作用下复合通风系统的机械排风速度规律特性研究，搭建了具有集中热源、集中污染源和顶面机械排风装置的实验模型．在自然进、排风口面积相同的情况下，通过改变机械排风速度和热源强度，分析了复合通风系统室内垂直温度分布、温度效率和排污效率的变化规律．结果表明：随着机械排风速度的增大室内工作区温度先降低后升高，而温度效率和排污效率先升高后降低．随着热源强度的增大最佳增益温度效率和最佳增益排污效率均降低．
Abstract:
Aimed at the ventilation efficiency, regular features of hybrid ventilation system combined with thermal natural ventilation and mechanical exhaust in the industrial workshop with concentrated heat source and concentrated pollution source a study is carried out . The experimental model with the same area of natural inlet and outlet, concentrated heat source, concentrated pollution source and mechanical exhaust device at the top is set up. The changing rule of indoor vertical temperature distribution, temperature efficiency and contaminant removing efficiency in the hybrid ventilation system are studied by changing the mechanical exhaust velocity and residual heat. The results show that as the mechanical exhaust speed increased, the temperature of indoor workspace first dropped and then rose, while ventilation efficiency first increased and then decreased. The maximum ventilation efficiency dropped as residual heat increased.
