摘 要: 探讨了地板送风和置换通风两种下送风方式在概念、机理、主要功能、特性及应用等诸多方面的差异与联系,分析比较了各自的优越性及局限性,提出了地板送风和置换通风各自的适用范围。地板送风作为一种节能空调系统应同时处理好通风换气和温度控制功能;置换通风由于加热和除湿问题,其应用在一定程度上受到了限制,但只要将其应用在恰到好处的场合,也可发挥出优势。 Described the difference and similarity between underfloor air distribution & displacement ventilation in concept,function, characteristic and application etc, analysed and compared their advantages and disadvantages and, presented theirdomains of application. Underfloor Air Distribution (UFAD) will be a dominant energy saving air conditioning system if theventilation and temperature control can be managed at the same time, so is Displacement Ventilation(DV) if used at anappropriate occasion, though it is applied within some limited occasion since it needs heating and dehumidificating.
