摘要
20世纪90年代以来,置换通风在世界范围内广泛应用。中国在引入北欧置换通风技术的基础上结合国情开展了这方面的研究与开发工作,首次应用于北京天桥剧场、上海大剧院,以及随后的杭州大剧院、国家大剧院等,目前在大量剧院工程中得到应用。针对几种不同类型的下送风器,在实验室测得其噪声声功率级及气流流速等数据的基础上,针对其气流分布和噪声特性等情况进行分析,旨在为实际工程设计及进一步深入研究提供借鉴和参考。
From the 1990s, displacement ventilation is widely applied in public buildings all over the world. Based on the Nordic displacement ventilation technology, China has been carrying out the research and development based on their national conditions, This ventilation system is currently applied in tots of theater projects, such as, Beijing Tianqiao Theater and Shanghai Grand Theater which were applied firstly, and then, Hangzhou Theater and Beijing China National Grand Theater. As part of the master＇s thesis and based on experimental data, the paper analysed the airflow velocity and the noise level for four different auditorium chair diffusers with umbrella-shaped Flow breaker. It may be used as a reference for other projects and similar chair outlets airflow noise research.
