摘　　要：随着打印机等办公设备不断进入生产生活,其释放的污染物造成的问题越来越受到人们的关注。目前,对打印机污染物的释放已有一定的研究,但如何有效减少办公室污染物却亟待解决。以某办公室为研究对象,建立物理模型,利用计算流体力学技术对冬季办公室原有空调柜机的通风方式、混合通风、层式通风展开模拟,分析三种通风方式的速度场、温度场、污染物浓度及PMV-PPD评价指标。研究发现,与原有的通风方式相比,层式通风方案最优,在相同的送风温度下,采用原通风方式70%的送风量即可达到相同效果,且气流均匀性和温度稳定性更好,工作区人员头部与脚部温差更小,热舒适性更强。As printers and other office equipment continue to become increasingly prevalent in workplaces and daily life,the problems caused by the pollutants they release have attracted more and more attention.At present,some studies have been conducted on the release of printer pollutants,but how to effectively reduce office pollutants needs to be solved urgently.Taking an office as the research object,a physical model was established,and computational fluid dynamics technology was used to simulate the ventilation methods,mixed ventilation,and floor ventilation of the original air conditioning cabinets in the office in winter,and the velocity field,temperature field,pollutant concentration and PMV-PPD evaluation index of the three ventilation methods were analyzed.The study found that compared with the original ventilation method,the layered ventilation scheme is the best.At the same supply air temperature,70%of the supply air volume of the original ventilation method can achieve the same effect,while providing better airflow uniformity and temperature stability.Additionally,the temperature difference between the head and feet of occupants in the work area is smaller,further enhancing thermal comfort.
