摘要
采用基于概率的多目标优化选择方法对低温(低于200℃)换热器相变蓄热材料进行优选。优选结果表明:以材料的相变焓值、热能释放量百分比、有效导热率、过冷度为目标函数,对相变材料进行综合评价和统筹优化是可行的。
Having probability-based multi-objective optimization selection method adopted to optimize the selection of phase-change heat storage materials for low-temperature(less than 200℃)heat exchangers was implemented.The optimization results show that,through taking the phase change enthalpy value,heat release percentage,effective thermal conductivity and the supercooling degree as objective function,comprehensively evaluating and optimizing the phase change materials become feasible.
