摘要
对长春、沈阳、北京的三个典型地下停车库的冬季运行情况进行了调查与测试,发现在未采用机械通风的条件下一氧化碳浓度并未明显超标。利用示踪气体法计算了地下停车库的自然通风量,并讨论了地下汽车库内一氧化碳允许浓度和小汽车一氧化碳排放量的确定。
Surveys and measures the operating conditions of three typical underground car parks in Changchun, Shenyang and Beijing in winter and finds that carbon monoxide concentrations are not obviously exceeding the standard limits when the mechanical ventilation devices not operated. Calculates the natural ventilation rate by the tracer gas decay method. Explores the definition of the indoor criterion of carbon monoxide concentration and the carbon monoxide emission from cars.
