不同空调模式下负压病房内污染物分布特性研究OA北大核心CSTPCD
Study on the characteristics of indoor pollutant distribution in negative pressure wards under different air conditioning modes
针对分体空调器、风机盘管都存在室内空气循环流动、冷凝水聚集等问题,本研究通过CFD软件对负压病房进行模拟,对比分析了辐射空调系统和风机盘管系统在负压病房应用时室内热湿环境、污染物分布特性和医护人员感染风险,并建立了全尺寸辐射空调负压病房实验室并对结果进行了验证.结果表明:采用辐射空调系统不仅能够降低室内垂直温差,减少吹风感,而且能够降低室内污染物浓度和室内人员感染风险;辐射空调与风机盘管相比室内污染物浓度、暴露风险和感染概率最大降幅分别为29.8…查看全部>>
In order to solve the problems of presence of indoor air circulation flow and condensate collection in both split air conditioners and fan coils,the negative-pressure wards were simulated using the CFD software,and the indoor heat and humidity environments,the characteristics of contaminant distribution,and the risk of infection for healthcare workers were compared and analyzed when radiant air conditioning systems and fan coil systems were applied in …查看全部>>
