Application Research Of CFD Technology In Air Condition System Design Of Run-Through Large Space

With rapid development of computational fluid dynamics (CFD), room air distribution can be predicted and all kinds of parameters can be analyzed by HVAC designers during design stages. So HVAC designers can select air distribution, which not only can safeguard arts demand, meet the thermal comfort of human body and create nicer internal air quality, but also attain energy-saving. However, there still remains a lot to do on the application of CFD technology in engineering design in our country and CFD technology can not assist design timely, which is also of great value to the researchers. CFD technology is applied to optimize the air distribution of china science & technology museum in this paper, which will solve the difficult problems existing in run-through large space.Run-through large space is a new kind of architectural form and number of it is limited. Function and trait of this architecture have great difference with ordinary large space. So we should not use same air distribution to design. By this cause, we will study deeply air distribution of this special large space. Firstly, on the base of simple model, this paper use commercial software Fluent to simulate the airflow, temperature field and velocity field in the run-through large space adopting standard k ?εmodel and the results of research are applied in the ectual engineering. Secondly, the article also introduces the basal principle of the CFD technology. Through the understanding and the research to the CFD technology, we can make the CFD more and more perfect in the principle and the technology methods. Lastly, through the simulation of air distribution in china science and technology museum and several projects of air-flow organization are evaluated with the standard. The writer chooses the best project depending on the results of the evaluation, which is adopted in the ectual engineering.This example exhibits the important function and development space of CFD technology in the optimum designing of air conditoning system. So application and study of CFD should be moved ahead to design stage and our researchers should put more energy on the application and study of CFD technology.
