电热相变储能供热装置的热效率模拟与试验研究
Thermal efficiency modeling and experimental research for electric heating units with phase change materials
摘要：
从能量守恒的角度出发，以装置表面的散热损失为主，推导出电热相变储能供热装置的热效率模型，对其进行了模拟计算，得出了热效率随供热量的变化规律。与实测结果的对比表明二者较为吻合。

Abstract：
Considering the heat loss in unit surface mainly, develops a mathematic model of the thermal efficiency.Obtains the variation regularity of thermal efficiency with heating load by simulation and calculation. The comparison result shows that the calculation results are close to the experimental data.
