Abstract

This study develops a novel micro heat pipe array (MHPA) heat exchanger integrated with porous flat aluminum channels and serrated fins, applied in a solar-air composite heat source heat pump system. Simulation analyses evaluate its performance under various operating modes: photovoltaic/thermal-water source (PV/T-WSHP), combined PV/T-water and air source (PV/T-W&ASHP), and air source (ASHP) modes. Results indicate that the MHPA heat exchanger dynamically redistributes thermal load, with water-side heat transfer decreasing from 1.4 kW to 1.2 kW as ambient temperature rose from 5 °C to 30 °C, while air-side heat transfer increased from 0.1 kW to 0.3 kW. Optimal system performance was achieved at an air velocity of 1.8 m/s, with COP reaching 2.24. The system demonstrated strong recovery capability, outperforming conventional finned-tube systems by up to 16 %. Increasing PV/T collector area to 10.2 m2 improved COP by 35.4 %, and serrated fins enhanced thermal absorption by 41 %, raising system COP by 22 %. Seasonal performance evaluation in Yichang climate yielded a high SPF of 2.41. The MHPA-based system offers efficient, stable dual-source utilization, supporting building energy savings and carbon reduction.
