摘要
针对我国气候差异大的特点及夏季降温问题,利用不舒适热指数分析了长波辐射降温的必要性,并基于1021 个代表城市的典型年气象数据,对国内气候差异性进行分析.利用EnergyPlus能耗模拟软件对典型建筑室内热环境进行模拟,以不舒适热指数、日照百分率、相对湿度作为分区指标,评估了全国长波辐射降温潜力.采用K-均值聚类的方法,将需要降温地区划分为长波辐射降温高潜力Ⅰ区、中潜力Ⅱ区、低潜力Ⅲ区、不适宜区.并针对各区提出了适宜的降温策略,为建筑师在设计前期提供更多的技术参考.
Abstract
Aiming at the characteristics of large climatic differences in China and the issue of cooling in summer,the necessity of long-wave radiation cooling was analyzed using the uncomfortable heat index.The domestic climatic differences were analyzed based on the typical year meteorological data of 1021 representative cities.The indoor thermal environment of a typical building was simulated by energy consumption simulation software-EnergyPlus,and the cooling potential of long-wave radiation was evaluated by taking the uncomfortable heat index and the percentage of sunshine as the partition indicators.The K-means clustering method was used to divide the areas requiring cooling into high-potential area Ⅰ,medium-potential area Ⅱ,low-potential area Ⅲ,and unsuitable areas for passive long-wave radiation cooling.Appropriate cooling strategies are proposed for each district,providing more technical reference for architects in the early design stage.
