The inner climate reaches various affects to peoples who lives the most of the day in an indoor. Moreover, according to the indoor thermal environment and amenities, the affect that it is many in the work efficiency is given. So, by using the various technical system in order to maintain the inner climate more agreeable, an air conditioner and ventilation facilities are operated. In the design phase of a building, the CFD analyzing technique is used as the most suitable method in order to predict the cooling and heating energy load distribution of a building. In not only the major construction company and facility design company but also the small scale facility design company, when seeing the reality used with generalization, the necessity of the CFD simulation is more obvious. However, various results coming from CFD analysis method cause not a few errors. Especially, it is judged which plays the important role among the air conditioner have great effect on in the CFD simulation result. But in the preceding research, in most cases are simply modeling like a square or a circular in the CFD modeling. Accordingly, the purpose of this study is try to check difference of characteristics of airflow according to the diffuser type. |
