大空间会议厅空调气流组织的数值模拟与实测研究

Numerical Analysis and Experimental Investigation on Air Distribution of Air Conditioning in the Conference Hall of Large Spaces

重庆某高级酒店大空间会议厅采用旋流风口上送风、百叶风口下回风的空调方式。本文以其气流组织为研究对象,利用CFD数值模拟与现场实测,得到了会议厅的温度和速度分布。结果表明,数值模拟结果与实测数据吻合较好,采用数值模拟预测大空间建筑空调气流组织具有较高的可靠性。

The air conditioning mode of swirl diffuser ceiling supply and shutter lower return was installed in the conference hall of a luxury hotel in Chongqing.The paper did a research on the air distribution.The distribution patterns of temperature and velocity was obtained by CFD numerical simulation and experimental investigation.The research shows that simulated result is consistent with testing data.Thus it is dependable to forecast air distribution of the air-conditioner in large space building by numerical simulation.
