Air distribution and microenvironment evaluation for partitiontype fancoil unit task air conditioning systems
摘要：
采用Kε三维湍流模型对一典型办公室工作区微环境进行了数值模拟，对三种送风速度下工作区的温度场、速度场以及人体吹风感和预期不满意百分率进行了分析研究。结果表明，房间温度呈分区分布，工位送风效率较高，可实现总体节能；在合适的送风速度下，可避免吹风感，保证良好的热舒适性。
Abstract：
Numerically simulates the microenvironment for typical office workspace with partitiontype fancoil unit (PFCU) task air conditioning system by a Kε threedimensional turbulent model. Analyses and studies the temperature and velocity distribution, the draught rating (DR) and the predicted percentage of dissatisfied (PPD) at three supply air velocities. The results show that the room temperature distribution appears zoning and air supplying efficiency is higher, which can achieve total energy conservation, and that the task air conditioning mode can provide better thermal comfort environment without draught rating when the air supply velocity is well designed.
