Research Of The CFD Technology In Optimum Design To The Air-Flow Organization Of HVAC System In Cinema

Enjoying the movie and the interpretation has become more and more important in our living with the development of the standard of the living. The cinemas and the theaters become more and more in the cities, the towns even the countries. The well HVAC systems can build the comfortable circumstance for the audiences in the cinema or the theater. The auditorium and the arena are the topic of the cinema, the lieu which holds a great amount of people, the object of the HVAC system. So the HVAC systems of the auditorium and the arena which judge the effect of the whole HVAC system are the most important parts of the whole cinema. The HVAC system infects the temperature field, the humidity field and the distribution of the contamination etc., it is the most important factor of the IAQ. But because of the limitation of the structure and the function of the cinema, there are many problems such as how to choose the correct air-flow organization, how to judge the effect of the air-flow organization, how to improve the capacity usage ratio of the air-flow organization. The CFD technology is the effective and economical method in the research for the aerodynamics in HVAC system, and it is also the direction of the HVAC field. The CFD can provide the accurate numerical simulation and forecasting of the distribution of the air-flow indoors. Through the simulation to the room with the CFD software, we can get the detailed distribution of the temperature, the humidity, the velocity and the density of the contamination. So we can make the correct decision to the design of the HVAC system with these technology backup. The author will research the air-flow organization of the HVAC system in cinema with the CFD technology, solve some problems which will encounter in designing and explore the application of CFD in HVAC field. The writer put forward the idea of optimum designing to the air-flow organization of HVAC system in cinema with the CFD technology, which bases on the characters of the cinema and the CFD. The writer also has summarized a set of standard which judges the effect the designing of the air-flow organization. The standard is based on the correlative information. 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. The writer heartily hopes that this article can favor the HVAC designers. A cinema model is simulated by the CFD software 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, and the data of the chosen project can be inosculated with the results of the experiments and the articles. This example exhibits the important function of CFD technology in the optimum designing to the air-flow organization of HVAC system in cinema. It also proves the correction of the idea and the standard of the optimum designing to the air-flow organization of HVAC system in cinema with the CFD technology. With the development of the computer technology and research to the HVAC system in cinema, the CFD technology will bring into play the more roles and the effect in the air-flow organization designing of HVAC system in cinema or even in the other buildings will be greatly improved.
