摘　　要：冷热电联供系统建立在能的梯级利用基础上,将发电、供热、制冷有机结合在一起。本文基于探讨燃气轮机的冷热电联供系统,通过对各子系统进行系统(?)分析,揭示了各独立变量对系统性能影响的内在规律,并明确指出了冷热电联供系统的系统节能率(约27％)以及系统集成的重要性。CCHP (combined cooling, heating and power) is based on the cascade utilization of fuel energy, and it combines on-site power technologies with thermally activated technologies. This paper analyses the CCHP with gas turbine, and it reveals the effect of some independent variables through exergy analysis in subsystems. Results indicate the features of system integration, and the saving ratio of fuel is as high as 27%.
