摘　　要：提出了一个由蒸汽回注燃气轮机、余热锅炉、燃气锅炉、双效蒸汽吸收式制冷机及电动压缩式制冷机构成的灵活热电比冷热电三联供系统,并且针对办公楼和宾馆两种典型建筑物的负荷,分别从热力、经济及环保性能三个方面对常规冷热电联供系统与灵活热电比联供系统的性能进行了比较与分析。结果表明,是否选用灵活热电比联供系统需要根据负荷确定;相对于常规冷热电联供系统,灵活热电比联供系统运行费用少,并且具有较好的热力、经济及环保性能;合理选用灵活热电比联供系统能缩短系统的增量投资回收期。Proposes a combined cooling,heating and power system with flexible heat-to-electric ratio composed of small-scale steam injected gas turbine,heat recovery steam boiler,gas boiler,steam doubleeffect absorption refrigerating machine and electric-driven compression type refrigerating machine.Based on the load of two typical buildings of office and hotel,compares the flexible heat-to-electric ratio cogeneration system with the traditional system from thermodynamic,economic and environmental protection performances.The results show that whether the cogeneration system applying small-scale steam injected gas turbine is adopted or not should be determined by the load characteristics;compared with the conventional system,the flexible heat-to-electric ratio system has less operation costs and better thermodynamic,economic and environmental protection performances;the reasonable selection of the flexible heat-to-electric ratio system could shorten the investment-increment payback period.
