Simulation Study on The Influencing Factors of MHPA-PV/T Module Performance in High-altitude and High-altitude Cold Regions

Abstract

This article uses Fluent simulation software to establish a three-dimensional steady-state model of MHPA-PVIT, and verifies the reliability of the model. The simulation results are in good agreement with the experimental results. Taking into account thermal efficiency, electrical efficiency, and losses caused by increasing flow rate, the optimal operating flow rate for MHPA-PVT components should be 0.15 kg/(m2 · s). The thermal efficiency decreases with increasing wind speed, while the electrical efficiency increases with increasing wind speed. And when the inlet temperature is low, the difference in thermal efficiency and electrical efficiency is small, but as the inlet temperature increases, the difference in thermal and electrical efficiency becomes more significant. The solar irradiance has a significant impact on the heat collection efficiency, and the heat collection efficiency of the components increases significantly with the increase of irradiance.
