人员密度设定对地下商业空间空调设计的影响

Influence of occupant density on HVAC system design in underground commercial spaces

人员密度设定对地下商业空间空调负荷计算、空调系统设计有着重要的影响,以济南某地下商业空间为例,定量描述了上述影响,提出了人员密度的取值思路及相关参考数据,给出了在不同人员密度下一次回风定风量系统冬、夏季的处理极限,对比了冬、夏季风量,结果显示,等送风温差下,冬季风量较夏季风量大。

Quantitatively describes the influence based on a real project in Jinan,Shandong Province.Studies the way to determine the occupant density value and supplies the related data.Calculates indoor conditions which can be handled by primary return air system with constant air volume under different occupant density and compares the air mass flow in summer and winter respectively.The analysis result shows that when supplying air under the constant temperature difference,the air mass flow will be larger in winter conditions.
