摘　　要：通过CFD模拟了风扇调风作用对典型建筑室内风场的影响,将调风作用下室内风速的调节区间作为研究依据。以PMV作为热舒适性的评价指标,研究了典型人体活动状况下,空调及空调加风扇调风两种工况下的风速和温度等因素的耦合关系,得出了引入风扇调风后满足热舒适性标准时的室内温度值,分析了风扇调风措施对建筑节能的影响及节能潜力,并提出了相关的节能建议。Taking control region of indoor air velocity under fan air adjustment condition as study basis,simulates the influence of fan air adjustment on velocity field in typical buildings by means of CFD software.Taking PMV as evaluation index for thermal comfort,studies the coupling relationship among air velocity,temperature,etc.,under the working condition of air conditioning with and without fan air adjustment under typical human body activity status.Obtains the indoor temperature value meeting thermal comfort standards with fan air adjustment.Analyses the influence of fan air adjustment measures on the energy saving of buildings and the potential of energy saving.Puts forward several suggestions for the energy saving of buildings.
