摘要
分析了燃气机热泵热电冷三联供系统节能的热力学原理及应用优势,探讨了不同季节采用不同的联供运行模式一次能源利用率PER的情况,并就影响PER的主要因素——废热回收率、热泵性能系数及用于发电的燃气能量占燃气总能量的比例的变动效应进行了模拟计算,给出了燃气机热泵不同联供运行工况下PER的对比及规律。
Analyses the thermodynamics principle of high energy efficiency and applying advantages of the gas engine-driven heat pump（GEHP） combined cooling heating and power, and discusses the PER of the GEHP at different combined supply energy modes. Simulates the effects on the PER when heat recovery rate, heat pump performance coefficient and the ratio of generating electricity energy to total energy are changed in different seasons, and compares the PER under the different combined supply energy conditions.
