摘要
川西太阳能资源丰富,但现行标准对平板太阳能集热器最佳倾角推荐范围过于宽泛,工程实践难以精细化设计。本文以川西6个典型城镇(甘孜、红原、九龙、理塘、马尔康、松潘)的气象数据为背景,运用规划求解和多元线性回归的方法研究了平板太阳能集热器逐日、逐月、冬季和全年的最佳安装倾角,分析了多种因素(纬度、赤纬、散射占比)耦合影响,得到了相关性较好的最佳安装倾角的拟合公式,并进行了预测验证。研究成果为设计人员提供了进行精细化设计、提高太阳能利用效率的有益参考。
Western Sichuan is rich in solar energy resources,but current standards have a wide range of recommended values for the best dip angle of solar collectors,and engineering is difficult to design meticulously.This paper takes the meteorological data of six typical towns in western Sichuan(Garzê,Hongyuan,Jiulong,Litang,Barkam and Songpan)as the background,the optimal installation inclination angles of day-by-day,month-by-month,winter-time and year-round installations for flat-plate solar collectors were studied by using the methods of planning solver and multivariate linear regression.The coupled effects of various factors(latitude,declination and scattering ratio)were analyzed.The fitting formula of the optimum installation inclination angle with better correlation was obtained and the prediction verification was carried out.The research results provide designers with useful reference for fine design and improvement of solar energy utilization efficiency.
