Abstract A novel heat pump with a hybrid condenser combined with flat plate micro-channel heat pipe (MCHP) plus thermoelectric generator (TEG) and Fresnel photovoltaic (FPV) evaporator is proposed and investigated in this paper. In the previous work, the TEG is inserted between the concentrated PV and absorber plate in the evaporator. Although the TEG can convert the heat stored on PV into electricity, it hinders the heat dissipation of PV, which affects the PV performance. However, if TEG is stalled in the condenser, it could improve the electrical performance and total performance of the system by transforming collected heat into electricity without affecting the heat dissipation of PV. In addition, the MCHP is used to collect heat in condenser to achieve a high heat flow density and high output of TEG. The results show that the addition of TEG in condenser could elevate the electrical and total performance of the system. The TEG not only increases electrical efficiency by 10.83% under 100 W/m2 irradiation, 292.15 K ambient temperature, and 303.15 K water temperature but also increases total exergy efficiency by 6.02% under 100 W/m2 solar irradiation, 286.15 K ambient temperature, and 297.15 K water temperature. The lifting effect is more significant under low solar irradiation. Moreover, the influence of solar irradiation, ambient temperature, and water temperature is also investigated and discussed.

新型热泵混合冷凝器结合平板微通道热管+TEG和FPV蒸发器的性能分析

摘要 本文提出并研究了一种新型热泵与混合冷凝器结合平板微通道热管（MCHP）+热电发电机（TEG）和菲涅尔光伏（FPV）蒸发器。在之前的工作中，TEG 被插入蒸发器中的聚光 PV 和吸收板之间。TEG虽然可以将光伏上储存的热量转化为电能，但阻碍了光伏的散热，从而影响了光伏性能。但是，如果 TEG 停在冷凝器中，它可以通过将收集的热量转化为电能而不影响 PV 的散热来提高系统的电气性能和总性能。此外，MCHP 用于在冷凝器中收集热量，以实现高热流密度和高 TEG 输出。结果表明，在冷凝器中加入 TEG 可以提高系统的电气性能和总体性能。TEG 不仅在 100 W/m2 辐射、292.15 K 环境温度和 303.15 K 水温下将电效率提高了 10.83%，而且在 100 W/m2 太阳辐射、286.15 K 环境温度和297.15 K 水温。在低太阳辐照下提升效果更显着。此外，还研究和讨论了太阳辐射、环境温度和水温的影响。15 K 水温但在 100 W/m2 太阳辐射、286.15 K 环境温度和 297.15 K 水温下的总火用效率也提高了 6.02%。在低太阳辐照下提升效果更显着。此外，还研究和讨论了太阳辐射、环境温度和水温的影响。15 K 水温但在 100 W/m2 太阳辐射、286.15 K 环境温度和 297.15 K 水温下的总火用效率也提高了 6.02%。在低太阳辐照下提升效果更显着。此外，还研究和讨论了太阳辐射、环境温度和水温的影响。
