架空地板送风系统技术探讨

Discussion on Underfloor Air Supply Systems Technology

探讨了架空地板送风系统的工作原理和特点,分析了该系统的送风静压层和送风特性,并从这种送风特性出发,综述了架空地板送风系统在室内空气品质、热舒适性和节能等方面的特点。通过分析,得出架空地板送风系统能够减小空气龄,提高换气效率和通风效率,显著改善室内空气品质;在热舒适方面,架空地板送风系统可以通过使用者调节出风方向和风量达到热舒适;在能耗方面,架空地板送风系统由于仅需维持工作区环境参数,使得送风量和风机压头减小,制冷机效率提高,在风机能耗和冷热源能耗上有着显著的经济效益。最后得出了架空地板送风系统将被广泛应用的结论。

The work principles and characteristics were discussed, the underfloor plenum for air supply and characteristic of air supply were analyzed. Based on the characteristic of air supply, features of IAQ, thermal comfort, and energy-saving were presented. From the introduction, with using underfloor air supply system, the air age can be decreased, the efficient of air change and ventilation are increased, and the IAQ is significantly improved. By adjusting the direction of fresh air and amount of air supply from users, the favorable thermal comfort is able to be offered. Because of only maintaining the environmental parameters of working space, the air supply and fan heat are decreased and the efficiency of refrigerating machine is increased, the consumption of fan energy, cold and heat source energy are reduced in underfloor air supply system. In addition, a conclusion of wide using ofunderfloor air system is made.
