Abstract
To create the comfortable ventilation in a room, the low flow speed ventilation to the ceiling has been investigated. The air flows in a model room and the natural convection around a human body were visualized by a smoke method and a technique of laser light sheet. Quantitative full-field velocity measurements were carried out by analyzing the flow visualization images by using a simplified density correlation method. At the same time, the CO2 concentration and the temperature distribution in the room were measured. The results indicated that the low speed ventilation air supplied to the ceiling is circulated in the whole region of the room, and a good air condition in the room can be performed under the appropriate ventilating condition. It was also found that the influence of the upward natural convection due to the human body was an important factor in the ventilation design.
