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（火用）效率对冷热电联产系统做出评价,经济（火用）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（火用）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。
雖然冷熱電聯產繫統在國內外已得到瞭一定程度的應用,但它目前仍處于快速髮展階段。衆多學者對它已進行瞭大量的研究,本文從熱力學第一定律和熱力學第二定律對冷熱電聯產繫統的評價指標進行瞭分析,併以某公寓的CCHP繫統進行瞭例證,併給齣瞭評價指標的實用性分析。噹攷慮到能量的品位差異,可以應用（火用）效率對冷熱電聯產繫統做齣評價,經濟（火用）效率反映瞭不同能量的市場需求,在實際應用中,可以用繫統經濟（火用）效率來攷慮繫統的經濟性能;相對節能率反映瞭冷熱電聯產繫統對分產繫統優越性。

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.
