为解决城市总规尺度气候评估工具缺乏的问题,分析了不同气候评估方法的特点和应用范围,研究了气象学工具WRF在城市热岛效应评估中的应用方法及有效性。建立了针对城市总规尺度的高精度城市规划信息数据库、气象数据库生成WRF模拟边界的方法;明确了高精度城市热岛效应模拟所需的WRF物理方案。以沿海城市大连夏季典型晴朗高温天气为例,利用WRF模型进行了300 m的高分辨率模拟。结果表明,WRF可以较好地模拟出城市热岛效应的强度和时空变化;将模拟结果与气象站和现场观测值进行了对比,两者变化趋势一致,偏差在可接受的范围之内。 相似文献

本文以全国省、市级区域1992—2020年夜间灯光为研究对象,基于DMSP和VIRS遥感影像以及城市行政区域矢量数据,采用一元线性回归分析方法构建灯光演变趋势,从时间和空间两个维度,并结合全国、分区和城市尺度对中国夜间灯光时序变化特征进行分析。结果表明:(1)研究年份内灯光增加多集中在东部沿海区域以及中部省会中心城市,灯光减少区域多集中在山西、陕西等中西部城市;(2)在中、东、西部时空变化中,东部区域增长区和高亮度区域面积占比最高,西部最低;(3)在19个典型沿海城市中,上海等东南部城市灯光增长最快且亮度最高,灯光增速和亮度值由高到低排列顺序为由南到北。 相似文献

Light envelopes are more and more frequently used in modern buildings but they do not present sufficient thermal inertia. A solution to increase this inertia is to incorporate a phase change material (PCM) in this envelope. This paper presents the performance of a test-cell with a new structure of light wallboards containing PCMs submitted to climatic variation and a comparison is made with a test-cell without PCMs. To improve the wallboard efficiency a vacuum insulation panel (VIP) was associated to the PCM panel. This new structure allows the apparent heat capacity of the building to be increased, the solar energy transmitted by windows to be stored without raising the indoor cell temperature, and the thickness of the wallboard to be decreased compared with that of traditional wallboards. An experimental study was carried out by measuring temperature and heat fluxes on and through the wallboards. The indoor temperature, which has a special importance for occupants, was also measured.A numerical simulation with the TRNSYS software was carried out in adding a new module representing the new wallboard. It showed a good agreement with experimental results. This new tool will allow users to simulate the thermal behaviour of buildings having walls with PCMs. 相似文献

本研究把灯具在寿命周期获得单位光能输出所使用的费用定义为该灯具的“光成本”.“光成本”是一种综合评价电光源照明产品在寿命周期内的成本费用与光能输出效果之间关系的客观价值指标,实现从光源的输出光能、寿命和成本三个维度来综合考察灯具的品质和价值.运用“光成本”概念对多种灯具分析,100W LED结温Ts=55℃灯具综合能效指标高于高压钠灯19.2倍,金属卤化物灯21 ~45倍.在相同的光效情况下,1只LED (Ts =55℃)灯相当于2只LED (Ts =85℃)的灯的使用寿命周期,相当于3只LED (Ts=105℃)的灯的使用寿命周期.在相同的光能输出情况下,LED (Ts=55℃)的光成本最低,与高压钠灯和金卤灯相比可节省2.4 ~3.4倍的光成本.通过上述“光成本”分析,不以单纯降低制造成本为目的,通过延长LED照明产品的使用寿命同样可以获得更好的经济效果,长寿命方案是LED照明产业发展的根本和新途径.LED照明长寿命才是高品质,长寿命就是低成本. 相似文献
