某报告厅空调系统的设计及其能耗分析

介绍了西安某办公楼报告厅空调系统的设计。分别应用置换通风与混合通风两种通风方式，在室外和室内设计参数相同的情况下，充分比较了它们在送风量、新风量、能耗以及室内空气品质的不同。结果表明在某些应用场合，置换通风在空气品质提高和能耗降低上有明显的优势，同时这种优势不以牺牲热舒适性为代价，因此建议使用置换通风系统。

Design and Energy Consumption Analysis for Air Conditioning System of A Meeting Room

Air-conditioning system for a meeting room in an office building in Xi'an is introduced. Two ventilation systems, the mixing ventilation system and displacement ventilation system, are applied respectively. The air flow rate, fresh air flow rate, energy consumption and indoor air quality under the same design parameters for the two schemes are compared. It is concluded that displacement ventilation is superior to mixed ventilation in improving indoor air quality and reducing energy consumption without sacrificing thermal comfort in some applications.
