摘　　要：本文利用Airpark软件对夏热冬冷地区典型办公楼层进行建模,分别模拟干盘管加全热回收新风系统、冷辐射吊顶加置换新风系统,通过不同的室内流场、温度场、速度场、PMV模拟结果,得出:夏热冬冷地区采用温湿度独立控制系统,工作区域温度基本可维持在24℃-26℃,PMV值均可以满足I级热舒适等级;冷辐射吊顶加置换通风方式,室内风速较低,温度场更均匀,优先应用在热舒适度要求较高的区域。The paper uses the software Airpark to model the typical office floors in hot summer and cold winter zone,and simulates dry coil plus total fresh air system with heat recovery,cold radiant ceiling plus replacement fresh air system respectively.Through different indoor flow field,temperature field,velocity field and PMV simulation results,The simulation results show that temperature and humidity independent control system is adaptive in hot summer and cold winter areas,and the working area temperature can be maintained within 24-26℃,and PMV value can meet Class I thermal comfort level.Cold radiation ceiling plus displacement ventilation has lower indoor wind speed and more uniform temperature field,which is preferred to be applied in areas with higher thermal comfort requirements.
