摘要
基于铁路空调车厢CO2浓度与所测新风量数值呈相关性,推导出的新风量数值可估算车厢新风供给状况,使新风量分析仪对旅客车厢新风量进行监测成为可能。该方法简便、快速,易于操作,能够即时了解旅客运输高峰期车厢中旅客实际获得的新风量,为相关部门监测评价旅客列车空气质量、调整通风量提供数据支持。
Fresh air supply can be estimated based on the correlation analysis of carbon dioxide concentration and fresh air volume in air-conditioned carriages. The feasibility study of monitoring fresh air volume via analyzer,with simple and accurate method,keeps tab on the air change flow within railway carriages during peak time,and provides data support of air quality monitoring and ventilation flux adjustment for the authorities.
