| 摘要: |
| 由燃气发动机和电动机联合驱动的混合动力热泵系统(HPHP)是提高燃气供热和制冷效率的发展方向之一，但其在系统设计和运行策略上还存在提升空间。本文提出了供热和供冷均由燃气发动机与电动机联合驱动的混合动力热泵系统，并建立数学模型。通过模型计算，针对设计工况下发动机提供60%动力下的混合动力热泵系统，分析不同环境温度下的供热运行策略和能源利用效率。结果表明：混合动力热泵可减小发动机容量，且发动机效率在中低温区间相比于燃气机热泵(GEHP)可提高3%~10%；同时一次能源效率也有较大提升，当室外温度为﹣5 ℃时，一次能源效率比燃气机热泵和电热泵(EHP)系统分别提高6.9%和5.4%，从整个供暖季的能效角度考虑，混合动力热泵具有较大的节能潜力。 |

| Abstract: |
| To improve the efficiency of space heating and cooling, the hybrid power-driven heat pump (HPHP) has been established. However, both the design method and operation strategy are too simplified, thus optimization is needed. In this paper, the HPHP with a gas engine and motor is put forward, and a mathematic model of HPHP is established to analyze its operation performance under a typical design (i.e., the gas engine takes 60% of the torque output under the design condition). The operation performance of the HPHP is also compared with gas engine-driven heat pump（GEHP）and electrical heat pump (EHP). The results show that the HPHP system can achieve 3-10% improvement of engine efficiency compared to the GEHP. The primary energy ratio (PER) of the optimized system is 6.9% and 5.4% higher than that of GEHP and EHP, as the ambient temperature is﹣5 ℃. The HPHP system can achieve higher energy saving potential for the whole heating season. |
