dc.description.abstract The cabin of the vessel is very narrow and airtight. And it is composed of the structures of the bunk beds, the clothes chest and the desk. According to the results of many previous research work on the air quality in the cabin, very poor indoor air quality was detected. The indoor CO2 concentration exceeded the standard value due to breath of people in the narrow space, and the large temperature difference appeared in the vertical as well as horizontal distributions. The purposes of this study are to lower the concentration of indoor air pollution, and to get uniform temperature and concentration distributions in the cabin. We conducted an experiment to examine the removal of Toluene with various diffuser types. An influence on the pollution material removal efficiency and the age of air with different types of diffuser were analyzed by numerical simulation using FLUENT. The data of concentration from the experiments and numerical simulations was relatively consistent each other. We compared the age of air with diffuser of vessel and building, and calculated TVOC (Total Volatile Organic Compounds) and CO2 removal efficiency to propose new diffuser of vessel. In case of our model, we found that the indoor CO2 concentration and the age of air are likely to fall within the acceptable air quality. -
