长沙某地下商场室内环境的实测与新风量的探讨

DISCUSSION OF FRESH AIR RATE AND MEASUREMENT OF THE INDOOR ENVIRONMENT OF ONE UNDERGROUND MARKETPLACEIN CHANGSHA

对长沙市某地下商场在空调系统调试前后的室内环境进行了实测,发现该地下商场存在着换气不足等问题,证实新风量的大小对二氧化碳浓度变化有着重要的影响,并对新风量的选取进行了探讨。本文对气候类似长沙的冬冷夏热地区的商场空调设计具有一定的参考价值。

Investigation of indoor environment is in Changsha before and after debugging of HAVC. conducted in one underground marketplace It is found that there exists problems such as insufficient ventilation rate. It approves that fresh air rate influences CO2 concentration. The determination of fresh air rate is discussed in this paper. This paper is valuable for the design of HAVC of marketplace in cold winter and hot summer like Changsha.
