Selections of typical meteorological year and example weather year and their effects on building energy consumption

Abstract

介绍了典型气象年和典型代表年的选择原理和几种常见的选择方法。不同的方法考虑了不同气象参数的加权因子和气象数据的连续性。介绍了将太阳辐射总量分为太阳直射辐射量与太阳散射辐射量的应用模型 ,并依据香港的气象数据 ,分别计算选出了香港的典型气象年与典型代表年。为了验证不同方法计算出的典型气象年与典型代表年对研究对象、系统的影响 ,作了一个实例建筑物能耗动态模拟。结果表明 ,不同典型气象年对模拟结果的影响偏差较小 ,而典型代表年的影响较大 ;选择合适方法计算的典型气象年对保证模拟评估结果的正确性具有重要意义 Presents the selection principle and several methods. Different method emphasizes different weighted factors of meteorological parameters and the continuity of meteorological data. For the sake of selection of typical meteorological year (TMY), provides an application model which divides solar radiation into direct solar radiation and sky radiation. Based on the local meteorological data, selects TMY and example weather year (EWY) of Hong Kong. In order to validate the influences of TMY and EWY obtained by different approaches on the research object and system, dynamically simulates the energy consumption of a building. The result shows that the deviation for TMY is much smaller, while the deviation for EWY is significant. Selecting TMY with a suitable method is significant in assuring the correctness of the assessment results.
