【摘要】 概述了各种用能评价分析方法的形成演变过程,重点介绍了能量系统用能动态分析新方法——(火用) 传递分析法。论述了该方法的理论基础和评价分析要点。对制冷制热装置现用的三种主要评价分析方法——能量分析法、(火用)分析法和(火用)传递分析法,从理论依据、准则系列及评价分析内容和目的,做了全面比较。在此基础上,阐述了制冷制热装置选择评价分析方法的原则,以及三种方法各自的适用对象。更多还原

【Abstract】 The forming and evolving history of all kinds of evaluating approaches to energy use was outlined. The method of exergy transfer analysis, a new method of dynamic analysis for energy systems, was mainly introduced. At present, having three kinds of main evaluating methods, energy, exergy and exergy transfer analysis, was adopted by both the refrigeration and heat pump systems. These methods were compared in overall basic theory, evaluating criterions, analyzable object and program. On the basis of these analysis, the elective principle of evaluating approaches for refrigeration and heat pump systems and suitable object of all kinds of evaluating approaches was expound.更多还原
