国家大剧院观众厅空调系统和气流组织方式的设计和分析

介绍了观众厅座椅下送风方案。通过对置换通风和空调系统下送风方式的分析和实测，总结出这种气流组织的设计计算方法。全年能耗分析显示，为达到高标准的卫生和舒适要求采用30m^3／h人均新风量的椅下送风空调方式，比15m^3／h人均新风量的混风变新风比空调系统制冷量增加50．9％。

Design analysis of air conditioning and air distribution in the auditoria of the national theatre

Describes the under-seat air supply mode adopted in the project. Provides a procedure of design and calculation based on analyses and field measurement. An annual energy analysis shows that 50.9% more in the cooling capacity is required for the adopted under-seat air supply mode to meet higher standard of comfort and indoor air quality with 30 cubic metre per hour per person than that by using a mixing air conditioning system with a common fresh air supply of 15 cubic metre per hour per person.
