摘要
The necessity and feasibility of the use of the personalized ventilation（PV）technology in a toll booth is described.First,the indoor environment of the toll booth equipped with a PV system is analyzed.Based on the analysis results,a set of equipment for controlling the indoor air quality（IAQ）of the toll booth is devised.Then,a full-scale model of the toll booth is set up in the laboratory.The airflow organization,the optimum operation parameters,and the restraint effects of the PV system on pollution are also experimentally studied.The experimental results on the air supply characteristics show that the PV system can effectively reduce the air age,improve the ventilation efficiency,and enhance the comfort and acceptability of human beings.In addition,this system plays a significant role in preventing pollution.
阐述了特定的公路收费亭环境下应用个性化通风(PV)技术的必要性和可行性.首先,分析了加装个性化通风系统的公路收费亭的室内环境,并基于分析结果,开发设计了一种收费亭内空气品质控制装置.然后,在实验室搭建了等尺度的模拟收费岗亭,研究了亭内气流分布状况、设备最佳运行参数以及个性化通风系统对污染物的抑制效果.系统送风特性的实验研究结果表明,个性化送风系统可以有效缩短空气龄,提高送风效率,提升人体舒适性和用户接受程度.此外,该系统还能有效抑制污染物的侵入.
