封闭空间CO_(2)浓度限值及呼吸空气供应

CO_(2) concentration limits and breathing air supply in enclosed spaces

通过分析封闭空间内CO_(2)浓度限值及其与呼吸空气供应量的关系,确定了紧急情况下向空调系统提供的呼吸空气量,并结合项目实例介绍了呼吸空气系统方案。

By analysing the CO_(2) concentration limits in enclosed spaces and their relationship with the breathing air supply,the amount of breathing air provided to the air conditioning system in emergency is determined,and a breathing air system plan is presented based on a project example.
