- Abstract
- This study is to analyze the performance of a radiation-panel cooling system by means of CFD. In the first step of this study, the indoor thermal environment of the office space, which is air-conditioned by radiation-panel cooling system, is analyzed by field measurement and CFD (coupled simulation of convection and radiation). With comparing the both results, the validity of the CFD method is examined from the practical point of view. In the next step, the thermal environment of the model office space, which is cooled by tree types of HVAC system (radiation-panel cooling system, all-air cooling system, and hybrid air-cooling system of radiation-panel and natural ventilation), is analyzed by CFD. Installing a human model in the room model, the characteristics of heat transfer from human are also analyzed. In the case of the radiation-panel cooling system, operative temperature and MRT(Mean Radiation Temperature) of the human model become lower than those in all-air cooling system. The radiation-panel cooling system is concluded as very energy-efficient in this study.
