剧场座椅送风气流组织数值模拟

Numerical Simulation of Air Distribution of Chair Ventilation

座椅送风是置换通风的一种具体形式,不同于传统置换通风的侧送风形式,我国在这方面设计规范也相应较少,又鉴于座椅送风初投资昂贵,在设计时有必要对其气流组织、舒适性等加以模拟预测。本文采用FLUENT软件对其空调系统的气流组织进行模拟研究,运用座椅送风的简化模型,模拟各种送风形式下的温度场和速度场,对比了各种送风形式的温度、速度、风量等因素,为大空间建筑空调系统优化设计、模拟气流组织提供了方法及理论依据。

The local air conditioning by chair,which is one kind of displacement ventilation systems different from the traditional forms,begins to be used in high-ceiling pubic building in China.The initial investment of chair ventilation is high,and the design specifications are also less in this regard,so it is necessary to simulation the air distribution, comfortableness and so on.The software of FLUENT used to simulate air distribution of air conditioning system is recorded in this paper.The processes of the using of the simplification model and the simulation method of chair ventilation,and then simulating the temperature field and the velocity field under various forms ventilation,including contrasting some facts like air temperature,velocity,the wind load of various forms ventilation,are all explained in the thesis.All these provide the effective basis for the optimized design.The study provides methods and theory of optimization design and air distribution simulation of air conditioning system in large space.
