摘要
依据热经济学的基本原则提出一种多产品输出系统的产品单位火用成本分摊方法.该方法认为,当系统输出是多种形式的产品时,各产品的单位火用成本应该与该产品的能级具有单调增的函数关系,并由此建立火用成本分摊方程.该方法在纵横两个方向上都体现了热经济学中的火用的不等价特性和火用成本递增的原则,并有机地将产品火用成本与产品的能量品质联系起来,适用于各种不同类型的能量系统.
Based on the principle of thermal economics,an energy sharing method of a product's unit exergy cost for a multiproduct output system is put forward.By using this method,it can be seen that the unit exergy cost of each product should have the monotune increasing function with the product's energy grade,and thus the exergy cost sharing equations are established.In the process of energy conversion and between energy conversions,this method reflects the unequivalent feature of exergy and the pricinple of exergy cost increasing progressively in ehermal economics and connects the exergy cost with the product's energy grade.This method is suitable for different kinds of energy systems.
