Study on the Airflow Organization and Human Comfort of a Small Conference Room in an Office Building under Summer Replacement Ventilation
The uniformity of temperature and wind speed are the important factors affecting the performance of displacement ventilation.The influence of gas supply(exhaust)spacing,gas speed and temperature on ventilation performance was analyzed by Fluent software.The results show that there are ventilation dead corners and heat accumulation on the surrounding walls of the space.It is reasonable to design a spacing of no less than 0.7m between the gas supply and exhaust vents.The larger the area of gas supply(exhaust vents),the more uniform the temperature and gas speed fields are.The gas supply temperature is around 21℃,and the indoor environment is closer to the human comfort zone's temperature.The research conclusion can provide reference for the design of small conference room's gas conditioning and ventilation system.
