热电冷联产节能判定的新方法

在深入分析热电冷三联产及分产系统Yong能级基础上，把热电厂能量转换过程中的能级利用与资金（初投资与运行费用）的时间效应有机地结合起来，提出了一种判定热电冷三联产节能的新方法－Yong能级价值因子法，并应用实例进行了论证，结果表明：应用Yong能级价值因子判定联产的节能，其综合体现了系统各主要热力学与经济学指标，可作为其投产前的热经济决策，使判定热电冷三联产是否节能更具有科学性。

The EELVFM for Judging the Energy Conservation of CHP

Based on the Exergy Energy Level(EEL) in the process of work energy conversion about the Cogeneration Combined heat&cool and Power(CHP)and the Heating/Generating/ Cooling /Parted/Generation(HGCPG),and combined reasonably with the time infected factor of its founds(initial and operation expenses), a new method Exergy Energy Level Value Factor Method (EELVFM) ,which is more scientific for judging the energy conservation of the system , is put forward. The example is given. And the results show that the EELVFM, which can be used to judge the economical in CHP before operation, is a comprehensive thermodynamics and economics index.
