二甲醚热泵与太阳能互补供能的经济性分析

Economic Analysis of Complementary Energy Supply between Dimethyl Ether Heat Pump and Solar Collector

提出二甲醚热泵与太阳能互补供能的工艺和经济性分析方法，在太阳能集热器供热比例不同时，进行特定条件下的经济性计算，提出了太阳能集热器供热比例为0.4～0.6时，经济性及供热效果最优。

The process and economic analysismethod of the complementary energy supply between dimethyl ether （DME） heat pump and solar collector are proposed. The economic calculation under the special condition is carried out when the heating percentages of solar collector are different. It is pointed show that the economy and heating efficiency are optimal when the heating percentage of solar collector is controlled at 0.4 to 0.6.
