摘　　要：从理论上分析热(冷)电联产系统的节能减排效果,得出对于不同的运行方式,热(冷)电联产系统要取得节能减排效果的用户侧热电比(热负荷与电力负荷的比)的条件式。介绍在现有的热(冷)电联产技术的基础上,利用理论分析的条件式,计算得出不同热(冷)电联产技术的不同运行方式下的用户侧热电比的条件值。通过分析,发现热(冷)电联产能否带来节能减排效果从理论上讲与热(冷)电联产技术(余热回收效率,发电效率)、电网发电效率、常用热源设备效率、运行方式、单位电网电力的CO2排放量和单位燃料的CO2排放量有关。By analyzing the energy saving and emission reduction effect of CCHP system,the condition expressions under different operating modes of heat and power ratio in user side（heat load and power load ratio） were obtained,when the CCHP system could get energy saving and emission reduction effect.Based on the existing CCHP technology and analysis of the condition expressions,the conditional values were calculated under different operating modes of different CCHP technology.The analysis demonstrates that whether the CCHP system could bring energy saving and emission reduction effect is relevant to the CCHP technology（hot recovery efficiency,power generation efficiency）,power grid efficiency,common heat source equipment efficiency,operating modes,CO2 emission of unit power network and CO2 emission of unit combustion.
