【摘要】 采用k-ε三维湍流模型对安装电脑显示器风口(computer monitor panel,CMP)桌面式工位空调系统的一典型办公室工作区微环境进行数值模拟,对3种送风速度下工作区及人体周围的温度场、速度场以及人体吹风感(draught rating,DR)和预期不满意百分率(predicted percentage of dissatisfied,PPD)进行分析与研究。研究结果表明,工位空调室内温度呈现分区分布,工位送风效率高,可以实现总体节能,在合适的工位送风速度下,可以为办公人员提供较佳的工作环境。
【英文摘要】 Numerically simulates the microenvironment of a typical workstations with computer monitor panel (CMP) task air condition system by k-ε3-D turbulent flow. Analyzes and studies the temperature and velocity distribution, draught rating (DR) and predicted percentage of dissatisfied (PPD) of the room and workstation in three supply air velocities. The results show that the room temperature presents partition distribution and the task conditioning has good air-supply efficiency, which can achieve total energy co... 附件下载
