摘　　要：直供式电采暖系统与相变蓄热式电采暖系统是两种截然不同的电采暖方案,本文利用静态分析法从初投资、年运行费用及简单回收期等方面预测其经济性。经济性预测结果表明,相变蓄热式电采暖年运行费用低,简单回收期较短,在节省电能方便更具优势。Direct-supply electric heating system and phase-change regenerative electric heating system are two different electric heating schemes. This paper uses static analysis method to predict its economy from the aspects of initial investment, annual operating cost and simple payback period. The economic forecast results show that the phase-change regenerative electric heating annual operating cost is low, the simple payback period is shorter, and it is more convenient to save energy.

关 键 词：直供式电采暖系统 相变蓄热式电采暖系统 经济性预测
