可再生能源建筑供能系统性能比较研究

Comparative Study on Performance of Renewable Energy Building Energy Supply System

为研究不同类型可再生能源建筑的供能系统性能,分别在两栋位置相邻,结构、体型、材料相同的教师公寓楼楼顶搭建了空气源热泵热水系统试验台与紧凑式全玻璃真空管热水系统试验台,进行了同环境、同周期系统性能试验,对供能系统性能及性能参数进行了分析,利用可拓理论分析得出:两种供能系统性能参数的权重系数相等;水温度对可再生能源供能系统性能的综合关联度Kj(1)为2.07,进水温度的综合关联度Kj(2)为2.04,气温的综合关联度Kj(3)为2.14,太阳辐射的综合关联度Kj(4)为4.97,日照时数的综合关联度Kj(5)为3.78。

The air source heat pump water system test bench and the compact all-glass vacuum tube solar water heating system test bench are built on the roof of two adjacent teachers'apartment buildings with the same structure,shape and material in order to study the performance of energy supply systems for different types of renewable energy buildings.The energy supply system performance and the performance parameters are comprehensively and systematically analyzed in the same environment conditions of the same period.The results show that the weight coefficients of the performance parameters of the two energy supply systems are equal by means of extension theory analysis.At last,the comprehensive correlation degree K j(1)of water outlet temperature on the performance of renewable energy power supply system is 2.07;the comprehensive correlation degree K j(2)of water inlet temperature is 2.04;the comprehensive correlation degree K j(3)of air temperature is 2.14;the comprehensive correlation degree K j(4)of solar radiation is 4.97,and the comprehensive correlation degree K j(5)of sunshine hours is 3.78.
