摘　　要：燃气轮机的楼宇冷热电联供系统是一种有前途的节能和环保的能源系统 ,该文对 1个已运行了 4年的系统进行了变工况和热力学分析计算 ,得出了该系统在夏季的设计负荷和变工况条件下能源效率和效率的数据 ,并进行了讨论和给出了结论。图 3表 3参 1Gas turbine-equipped building cooling, heating and power(BCHP) generation system should have a great future, for it is particularly helpful in achieving the goals of energy efficient use and environment protection. An on-site BCHP system being domestically one of the first such systems was installed and put to use four years ago. As the first step to evaluate the project, computations have been made to know about the off-design performance and the efficiencies of the system on energetic and exergetic bases for the operation mode in summer. Discussions and analysis have been made mainly in terms of energetic and exergetic efficiencies. Conclusions have been given. Figs 3, tables 3 and refs 10.
