基于f-图法节能住宅太阳能供暖系统技术经济优化
he Technical and Economic Optimization of solar heating system for energy-saving residence buildings with the f-chart method
在根据《太阳能供热采暖工程技术规范》（GB50495-2009）进行设计计算时，太阳能保证率对选择最合理、最经济的太阳能供暖系统有着关键性的影响。以太原为例利用f-图法分析计算了寿命期内节能50%住宅太阳能供暖系统的经济性，计算得出了太原地区节能50%住宅太阳能供暖系统最佳的太阳能保证率为43.85%；并在此基础上分析计算了集热器价格变化对整个系统经济的影响，得出了寿命期内最大节省费用和最佳的太阳能保证率随着集热器价格的降低而提高这个结论，当集热器价格降低11.11%时，寿命期内最大节省费用可以提高84.33%，太阳能保证率可以提高到53.5%。
While designing a solar heating system based on The Technical Code for Solar Heating System (GB50495-2009), the solar fraction, f, has an important impact on the selection of the most reasonable and most economical solar heating system. Taking Taiyuan as an example, the economy of the solar heating system for 50% energy-saving residence buildings in the life period is calculated with f-chart method, and the optimum f of this region is 43.85%; and based on that, the impact on the economy of the whole system from the collector price changes，the result is that the maximum saving and the optimum f increases with the decrease of the collector price，when the collector price drops by 11.11%，the maximum saving increases 84.33% and the optimum f is up to 53.5%.
