%X 以置换通风水平方向送风角度为变量，对设有冷却顶板和置换通风复合空调系统会议室室内环境进行 动态模拟研究，并从气流温度场、速度场、PMV和PPD值等角度进行模拟结果分析.结果表明室内会议桌对空 调房间气流场会造成较大影响；通过分析几组置换通风水平方向不同送风角度模拟结果，可知送风角度处在 稍小于“临界角”范围内时较传统送风角度下的室内空气品质有所提高.</br>Takingthedisplacementventilationairsupplyangleinhorizontaldirectionasthevariable,thispaperdoesa studyofdynamicsimulationonthemeetingroomequippedwithcoolingceilinganddisplacementventilationair-condi? tioningsystem,andanalyzedthesimulationresultsofairflowtemperaturefield,velocityfield,PMVvalueandPPDvalue.
