摘　　要：本文通过数值模拟方法研究了碰撞射流通风供冷系统下送风参数变化对大空间办公建筑内区热环境特征及能耗的影响。详细分析了碰撞射流送风参数变化对建筑内区温度分层,人员吹风感和能量利用率等方面的影响效果及其相关性,给出了兼顾人体热舒适与节能要求的送风参数参考范围。Under the impinging jet ventilation system of cooling,the influences of the air supply parameters on the characteristics of the thermal environment and the energy consumption in the inner zones of the large space office buildings were numerically simulated.The effects and correlations of the changes of the airflow parameters of the impinging jet on the thermal stratification,draft sensation and energy-using efficiency are analyzed in detail.The reference range of the air supply parameters considering the thermal comfort and energy saving requirements is given.
