摘　　要：采用实验测试结合理论建模的方法,研究了应用辐射制冷技术对高铁站房类高大型建筑物内部温度和空调系统(制冷和采暖)能耗的影响,以杭州西站站房为例分析了应用辐射制冷技术前后空调系统能耗及室内舒适度的变化情况。结果表明:辐射制冷技术在杭州西站站房屋面的应用能够大幅减少杭州西站站房的空调负荷,空调系统(制冷和采暖)年节能率可达到38.9%,尤其对于峰值负荷可达到60%,并显著改善建筑内部人体舒适度,旅客对站房内部热环境的不满意率由23%降低至5%,表明辐射制冷技术是在类似建筑物领域实现“双碳”目标的重要途径之一。The effect of radiative cooling on temperatures and air condition energy consumption of high-speed railway stations are studied based on experimental testing and modeling.Taking Hangzhou West Railway Station as an example,internal temperatures,air condition energy consumption,and human comfort level before and after applying radiative cooling films is analyzed.The results show that the application of radiative cooling could greatly reduce the yearly air condition energy consumption of the station by 38.9%;the peak cooling load can be reduced by up to 60%,and the human comfort inside the building(the dissatisfaction rate of passengers with the thermal environment inside the station room has been reduced from 23%to 5%)is significantly improved,indicating that the radiative cooling technology is one of the most important way to help similar buildings achieving the“carbon peaking and carbon neutrality”goals.
