【摘要】 本文选用一应用置换通风方式的典型办公室房间作为研究对象,应用数值模拟方法,从室内空气温度分布、速度场、PMV-PPD及空气龄几方面模拟研究了置换通风条件下室内空气品质。结果表明置换通风方式下空调房间具有较好的热舒适环境和良好的室内空气品质。更多还原

【Abstract】 This paper chooses a typical office which applys displacement ventilation for the research object, by adopting numerical simulation, the IAQ of a room with displacement ventilation are simulated and studied from the aspects of the distribution of field of temperature and velocity, PMV-PPD and THE AGE OF AIR.Draws a conclusion that the room with the displacement ventilation can maintain a thermally comfortable environment and better indoor air quality.更多还原
