摘要
针对购物中心、餐厅、停车场和办公区等不同功能区的地下空间中室内空气质量影响进行了现场监测研究,主要研究了人群活动对室内二氧化碳浓度的影响规律,为今后改善地下空间室内空气质量提供了设计依据。通过研究发现:CO2浓度随人流量的增减同步变化,室内空气中的CO2浓度与人流量呈现正相关性。停车场和办公区的CO2浓度相对于购物区和餐厅比较低,最高不超过0.10%;而购物区和餐厅的CO2浓度比较高,人流量最高时可达0.18%。因此,今后地下空间通风系统设计时,应根据现场实际可能出现的人流量情况,进行新风量调节,以达到节能和改善室内质量环境双重目的。
In order to characterize the effect of people activities on CO2 concentration in underground environment, a underground space with function of shopping malls parks and offices was selected for this study. This may provide consultation for improving the underground space air quality. A positive correlation between people activities and CO2 concentration was observed. The result of CO2 concentration in parks and offices was lower than that in shopping malls and restaurants, and the highest concentration in parks and offices does not exceed 0.10%. The CO2 concentration in shopping malls and restaurants were comparatively high. It reached 0.18% for the most people activities. Therefore, the fresh air volume should be adjusted according to people activities to save energy and improve indoor air quality.
