某剧场夏季座椅送风气流组织的测试分析

Test and Analysis on the Airflow Organization of Seat Supply-Air in a Hall in Summer

近年来对置换通风的研究越来越多,但大多局限于数值模拟,针对一实际工程,测试了剧场内座椅送风条件下观众附近的空气温度和流速,分析了测试结果,结果是座椅送风气流组织的空气流速比较小,气流造成的不舒适感小,但是由于设计中考虑的不全面,出现了南北侧温差大,楼座池座温差大的缺点。

Recently the study on the displacement ventilation is increasing .but majority of them are only numerical simulation. For an actual engineering, we test the air temperature and velocity near audience in the hall with displacement ventilation are tested and analyzed. It shows that the air velocity is relatively small of the airflow organization of seat supply-air, and the uncomfort resulted by airflow is little. But because of un-sufficiency of advisement in engineering designing, it finds that there are some defects, such as the big difference in temperature between south and north, the big difference in temperature between storey-seat and pool-seat.
