摘　　要：为了突出体现冷热电联产技术的节能特性,用理论分析的方法,建立了冷热电联产系统热经济性评价的数学模型。为了进一步验证冷热电联供系统的节能特性,在产生相同电量、制冷量和供热量的条件下,对冷热电联产和分产系统的热经济性进行了对比计算,得出并比较两种系统的一次能耗率、煤耗量以及制冷机的当量热耗系数,计算结果表明冷热电联产系统比分产系统更加节能。To highlight the energy-saving features of CCHP technology,the mathematical model for the evaluation of thermal economy of CCHP system is built by using theoretical analysis. In order to further verify the energy-saving features of CCHP,this paper also makes the comparative calculation in terms of thermal economy between CCHP and generation systems under the conditions of the same amount of power,cooling capacity and heat supply,then primary energy rate,coal consumption and equivalent thermal coefficient of refrigerator are compared between the both systems. The result shows that CCHP systems are more energy-efficient than generation systems.
