气候变化对办公建筑极端负荷的影响
Influence of climate change on office building extreme load
摘要：
利用TRNSYS能耗模拟软件模拟了1961—2009年天津市典型办公建筑的供暖和供冷负荷，结合同期气象资料，着重分析了建筑极端负荷与气候变化的关系。结果表明，1961—2009年办公建筑供暖极端负荷日数极显著下降，而供冷极端负荷日数无显著变化；供暖期和空调期过渡月份的极端负荷日数出现较少，供暖期极端负荷占总负荷的比例呈减小趋势，在空调期的变化不大；供暖极端负荷日数主要受气温的影响，而供冷极端负荷日数除受气温影响外，还与相对湿度的变化有关。
Abstract：
Simulates the heating and cooling load of a typical office building in Tianjin during 1961-2009 using energy simulation software TRNSYS. Particularly analyses the relationship between building extreme load and climate change with meteorological data of the same period. The results show that the extreme heating load days of the office building significantly decrease, while the extreme cooling load days do not change significantly from 1961 to 2009. Less extreme load days occur in transitional month during both heating and cooling periods. The contribution of extreme load in the total load shows large decrease in heating period, but it changes little in cooling period in the past 49 years. The extreme heating load days are mainly influenced by temperature, whereas the extreme cooling load days are related to temperature and relative humidity.
