摘要
通过对影响换热系统可用能费用损失的各种因素进行分析,综合考虑换热器的材料消耗费用,提出了基于热力学第二定律的对换热系统进行优化的目标函数,并利用工程热力学、流体力学及热经济学的理论对目标函数进行了推导,得到了目标函数的计算公式。
Through an analysis of the various factors liable to affect expenses caused by the loss of available energy of an heat exchange system a comprehensive consideration has been given to the material consumption expenses of a heat exchanger. A target function based on the second law of thermodynamics was proposed for the optimization of the heat exchange system. Moreover, by making use of the theory of engineering thermodynamics, fluid mechanics and thermo-economics a derivation of the target function was carried out, resulting in the acquisition of a calculating formula for the target function.
