以2010年太阳能十项全能竞赛中天津大学参赛作品Sunflower为研究对象,通过数值模拟和实验数据定量分析的研究方法,重点针对零能耗太阳能建筑主动节能技术系统3种不同工况方案优化选择,对其进行模拟分析和实验验证。结果证明:利用混合灰色关联多层次综合评价法对太阳能建筑主动技术系统优化评价是一个科学有效的优化方法,具有良好的实用价值;太阳能+地源热泵+冷、温双槽水蓄冷+风机盘管空调系统在太阳能利用效率、经济、节能和社会方面具有良好的效果。
Based on the Sunflower project of Tianjin University participating in the 2010 Solar Decathlon Competition, this paper focuses on the optimization of three different working modes of active energy-saving technologies in zero-energy solar energy buildings through numerical simulation and quantitative analysis of experimental data. Its simulation analysis and experimental verification. The result proves that it is a scientific and effective optimization method to optimize the evaluation system of solar building active technology by the method of mixed gray correlation multi-level comprehensive evaluation, which has good practical value. Solar + ground source heat pump + cold and warm double tank water storage + fan disk Tube air-conditioning system in solar energy efficiency, economic, energy-saving and social aspects with good results.
