| Popis: | 102 With the change in lifestyle, each person spends an average of 80~90% a day in the indoor environment. Therefore, the indoor air quality plays an important role in the public health. The airflow field and human thermal comfort in the building room are also the necessary factors on the integrity assessment of the indoor environment. This study focused on the measurements of indoor air quality, investigations of human thermal comfort and airflow fluid in a campus convenience store. The difference between simulation and measurement were discussed. The results revealed that the carbon dioxide concentration was higher in the weekday than that in the weekend. The concentrations of carbon dioxide were out of limits in most of time. According to the investigation of human thermal comfort, the neutral state highly occupied the mode values and the questionnaire results. It showed the acceptable range of human thermal comfort and the similarity between the mode values and questionnaire results. However, there were a short circuit and death zone phenomenon in the indoor air distribution. The areas of dead zone were easily accumulated by carbon dioxide. The final discussion provides better improvement strategies, the displacement ventilation, the horizontal ventilation and the modification of 30 ° air supply angle. After considering the cost limits, the modification of 30 ° air supply angle is the best strategy. |
