空调房间室内气流组织的数值模拟研究及应用

The Research on Numerical Simulations of Velocity Field and Temperature Field of Airflow in Air-conditioned Room and Application

合理的气流组织是空调房间气流组织设计的主要内容,他不仅影响空调房间的空调设计参数,而且对整个空调系统的合理运行产生重要影响。采用CFD技术研究了送风参数对室内空气速度场和温度场的影响,并对其速度场和温度场进行数值模拟解算,解算结果与实际物理过程基本吻合,完全可以作为空调房间气流组织设计的一种技术手段,从而大大缩短了设计周期,同时对于改善室内空气品质、提高控制室内空气污染物能力、以及保证实现最优化设计都有着重要的指导作用。

Reasonable airflow organization is a mostly content in design of airflow in air-conditioned room, which not only effects design parameters of air-conditioned room, but also heavily effects reasonable operation of whole air-conditioned system. The authors, by using CFD technology, researched the influences of air inlet parameters on air velocity field and temperature field indoors, calculated the numerical simulation of velocity field and temperature field. The result is in accord with the fact physical process. It is completely regarded as a king of technology measure so that the design period is greatly shortened. At the same time, it can give important instructions to improve IAQ, enhance the ability to control indoor＇s air contamination, and ensure realization of optimization design.
