天桥剧场观众厅池座椅背送风方案研究

由于下送风方案可以减小能耗，降低噪音，天桥剧场观众厅池座拟采用下送风方案。本文对天桥剧场观众厅池座部分采用椅背送风时的效果进行了模拟计算，计算工况包括不同的送风温度和不同的诱导比。数值计算结果表明，采用椅背送风，观众身体周围的风发布合理，头部，躯干和大腿处的温度合理，下会对观众造成吹风感或闷热的感觉，当诱导比增大时，送风气流作用的范围增大，人体周围的温度场更加均匀，当送风温差减少时，人体周围的温度

Study on the Displacement Ventilation in the Poolof Tianqiao Theatre

Displacement ventilation is adopted in the pool of Tianqiao Theatre because ofits energy - saving and low noise .The effect of displacement ventilation from the rear of chairs was analyzed with CFD method .There are 4 casesincluding differentinletairtemperatures and induced airratio.Itis shown thattem perature distribution is good enough to ensurethe thermal comfort.Thetemperature around people tends to be more uniform with the incraese ofinduced airratio orthe decrease oftemperature difference ofsupply air.
