摘　　要：利用ESP-r数值模拟平台,完成建筑能耗模拟研究。基于香港和北京的气候条件,分析了液流窗在体育馆中的应用节能潜力。结果表明,相比于IGU窗体,采用液流窗可以有效降低建筑物的太阳得热量和建筑室内冷负荷。但是,也会同时导致建筑冬季采暖热负荷的上升。然而,由于液流窗兼具集热器的功能,其应用还有助于促进热水系统的运行节能。整体而言,其应用可以有效促进建筑的综合运行能耗降低。此外,液流窗的节能性会受到太阳辐照水平和环境温度等气象条件的影响。In this paper,building energy simulation was completed with ESP-r platform.Energy saving potential of liquid flow window(LFW)was investigated based on its application in a sport center under the weather conditions of Hongkong and Beijing.Results indicated that comparing to Insulated glazing unit(IGU),direct transmitted solar heat gain through the window and building cooling load could be effectively reduced with LFW.However,the heating load in winter season was found increased at the same time.Nevertheless,the application of LFW resulted in energy saving in water heating system because of its solar thermal collection.Generally speaking,its application promotes the saving in energy consumption for building operation.Furthermore,energy saving performance of LFW was also affected by weather parameters including solar intensity and ambient temperature.
