大空间建筑室内气流组织数值模拟与舒适性分析

分别对采用百叶侧送侧回、喷口侧送侧回、散流器顶送下回、分层空调、置换通风方式的大空间建筑空调室内气流的速度场和温度场进行了数值模拟,并对其结果进行了实验验证。根据ADPI指标对这几种送回风方式进行了热舒适性评价.结果表明,分层空调和置换通风是大空间建筑中较好的气流组织方式。

Numerical simulation and thermal comfort analysis of indoor air distribution in large space buildings

Numerically simulates the velocity field and the temperature field in large space buildings separately adopting register sidewall air supply and sidewall return, nozzle outlet sidewall air supply and sidewall return, diffuser ceiling air supply and below return, stratificated air conditioning and displacement ventilation, and verifies the results by experiments. Based on the index of ADPI, evaluates these air supply methods in thermal comfort. The results indicate that stratificated air conditioning and displacement ventilation are better modes for air conditioning in a large space buildings.
