| 摘 要： | 建立复式住宅的三维数理模型,利用CFD软件对复式住宅室内气流组织进行数值模拟,探讨室内温度场和速度场的变化关系,分析2种客厅内不同空调安装位置对复式住宅室内气流组织和热舒适性的影响.结果表明:客厅内空调送风只能同时保证客厅内主要活动区域,以及与其直接连接的相邻且无遮挡空间的空气温度满足要求;在送风时,位于客厅内上层卧室外墙上方空调比位于客厅内西墙墙壁上方的空调对室内气流的扰动作用更大,对室内风速及温度的影响也更大.这对于复式住宅内空调优化设计和节能具有指导意义.

| Abstract: | Three-dimensional physical and mathematical models of duplex apartment were established in this paper.Indoor air distribution of the duplex apartment was simulated by using computational fluid dynamics software CFD,and the impact of the different installation position of air conditioning on indoor air distribution in summer were analyzed.By comparing the change relations of the indoor temperature field and velocity field in different circumstances,and the influence of two installation positions of air conditioning that meet the requirements of air distribution and thermal comfort in the duplex apartment were analyzed.Results show that air supply of air conditioning inside the drawing room only meet air temperature requirements of the main activity areas of drawing room and its' directly connected neighboring space without occlusion at the same time;and the disturbance effect of indoor air flow fluctuates more fiercely when air conditioning located in the indoor central position than the border,as well as the influence of indoor wind speed and temperature. |
