某家具汇展中心气流组织的优化设计

合理的室内气流组织形式对提高空调系统的舒适性、降低系统能耗有着重要的作用。以某家具汇展中心为研究对象，建立展厅室内空气流动和换热的三维紊流数学模型，采用CFD技术对侧送侧回、上送下回和上送上回3种气流组织方式条件下的温度场和流场进行数值模拟。模拟结果表明，上送下回气流组织形式不但可以节省系统初投资，还可以达到更加节能的要求，是一种更为合理的气流组织方案。

Optimization design of the air flow organization for one furniture exhibition center

Reasonable air flow organization plays an important role in the improvement of the room thermal comfort and the energy consumption of the air-conditioning system. Builds three dimensional turbulent numerical model to simulate the air flow filed and the heat transfer of the furniture exhibit room. Using this CFD model, simulates the temperature field and flow field under three kinds of air supply type. The results show that air up supply and down return system has the advantage in reducing first investment. It is an energy-saving air flow organization type for the present design.
