摘要
依据热力学第二定律的(火用)分析方法,从能量利用的全过程出发,考虑输送能耗的影响,利用能源(火用)效率代替设备的能量利用效率对热电冷三联供的集中供冷和常规的电供冷方式进行了比较,从而得出了更客观、合理的结论,为合理采用热电冷三联供的集中供冷方式提供了判断依据。
Based on the exergy analysis method of the second law of thermodynamics, the centralized cooling of a combined heating, cooling and electricity system and the regular electric cooling were compared from the energy use of entire process, especially the influence of the transportation energy consumption. It has drawn an objectively, reasonable conclusion, which will do great help for popularizing the centralized cooling of a combined heating, cooling and electricity system.
