摘要
虽然冷热电联产系统在国内外已得到了一定程度的应用,但它目前仍处于快速发展阶段。众多学者对它已进行了大量的研究,本文从热力学第一定律和热力学第二定律对冷热电联产系统的评价指标进行了分析,并以某公寓的CCHP系统进行了例证,并给出了评价指标的实用性分析。当考虑到能量的品位差异,可以应用()效率对冷热电联产系统做出评价,经济()效率反映了不同能量的市场需求,在实际应用中,可以用系统经济()效率来考虑系统的经济性能;相对节能率反映了冷热电联产系统对分产系统优越性。
Although the CCHP system has been a certain degree of application at home and abroad, but it is still in the stage of rapid development at present. Many scholars have conducted a lot of research. This article from the first law of thermodynamics and the second law of thermodynamics on CCHP system was evaluated by a lot of analyses, taking a certain apartment CCHP system for example and the evaluation indexes are given practical analysis. When considering the energy grade difference, exergy efficiency can be applied to make evaluation for CCHP system, economic exergy efficiency reflects the market demand of different energy. In practical application, we can use the efficiency of system economy exergy to consider the system economy energy; relative energy saving ratio reflects the CCHP system on the superiority of system.
