| 摘 要： | 燃气机热泵是以燃气机作为动力来驱动的压缩式热泵。对燃气机热泵的热力学第一定律、Yong分析和能级平衡理论分析结果表明：其一次能源利用率可达1.76，Yong效率为0.291，能级平衡系数为0.394。与电动热泵等其他供热装置相比，燃气机热泵有着较高的热力学完善性，是一项高效节能技术。由于能级平衡理论分析考虑了Wu的作用，而热泵供暖时其性能系数的提高主要是利用了环境热量，所以建议采用能级平衡理论来分析评价热泵的性能。

| Abstract: | Gas Engine-driven heat pump (GEHP) is the compressed heat pump driven by gas engine. Results of the first law thermodynamics analysis, exergy analysis and energy grade theory show that the primary energy ratio of GEHP is 1.76, the exergy efficiency is 0.291 and the energy grade balance co efficiency is 0.394. Compare to other heating device such as electric driven heat pump, GEHP has upper thermodynamics performance, and is a high efficient energy saving technology. Because the energy grade theory analysis take into account anergy with which heat pump do enhance its performance, so in this paper the author suggests that the energy grade theory analysis should be used when evaluate the performance of heat pump. |
