上海地区建筑能耗计算用典型年气象数据的研究

以同济大学某教学楼为研究对象,对比了用EnergyPlus模拟计算得到的全年耗电量和实测耗电量,研究了用于建筑能耗动态计算的5套典型年气象数据的可靠性,得出了CTYW气象数据最接近现实情况的结论。对其中影响较大的参数如室外气温、湿度和太阳辐射量进行分析和比较,指出所用5套典型年气象数据间的差异来自观测值的缺损和统计处理模型的不完善,特别是日射模型存在一定缺陷。

用典型年数据计算供暖负荷朝向修正系数

以各气象台站实测典型年气象资料为基础,综合考虑了直射辐射和散射辐射两种情况,给出了全国27 个城镇的各朝向修正系数。

太阳能辐射资源计算分析与特性模拟方法

采用太阳辐射理论计算及TRANSYS气象系统进行辐射资源计算和特性模拟。由每月典型日的辐射量推算出地外、水平面、倾斜面的辐射量以及总、直射辐射的月、年总辐射量;分析不同日照百分率下的总辐射量和直射辐射量;利用TRANSYS模拟地外、水平面、倾斜面的总辐射量和直射辐射量的变化情况。计算分析表明:对于鄂尔多斯达拉特旗地区而言,其年总太阳辐射量达9916 MJ/m^(2),倾斜面年总太阳辐射量可达7675 MJ/m^(2)。水平面与倾斜面辐射情况大有差异。该文的计算模拟方法也适用于任何地区的太阳能辐射量计算。

广东省水平面日散射辐射月均值估算模型比较

基于前人研究提出的8个水平面日散射辐射月均值估算模型,采用广东省内的8个地区的典型气象年数据,以均方根误差(RMSE)、平均绝对误差百分比(MAPE)、相关系数(R2)作为模型精度的评价指标,对8个估算模型进行了对比验证,结果表明Li提出的模型适用于广东省。

The Generation of Typical Meteorological Year and Climatic Database of Turkey for the Energy Analysis of Buildings

For sustainable development, a reduction in energy demand is essential. This could be achieved through improving energy efficiency, effective energy conservation and management. The weather conditions of a given region are the most important consideration for the proper design of space AC （Air Conditioning） systems. In this study, the typical meteorological year and climatic database of Turkey for the energy analysis of buildings were generated by SQL （Structured Query Language） database programmimg language. The Finkelstein-Schafer statistical method was applied to analyze the hourly measured weather data of a 23-year period （1989-2012） and select representative TMMs （Typical Meteorological Months）. The selection criteria were based on 13 meteorological parameters. These parameters are the daily mean, maximum and minimum values and ranges of temperature, dew-point and wind velocity and the daily values of global solar radiation. According to results of TMY （Typical Meteorological Year）, climatic database of Turkey including daily or hourly climate variables was created in SQL data tables.
