Low-cost PCM-embedded stainless-steel wool with copper tube for enhanced thermal management in water-based photovoltaic-thermal collectors: Experimental and numerical study

Description

This dataset supports the manuscript entitled “Low-cost PCM-embedded stainless-steel wool with copper tube for enhanced thermal management in water-based photovoltaic-thermal collectors: Experimental and numerical study.” The data include experimental and numerical results used to evaluate the thermal and electrical performance of a water-based photovoltaic-thermal collector integrated with PCM-embedded stainless-steel wool and a copper tube thermal management structure. The dataset contains spatial irradiance distribution measurements collected across the collector surface under three operating settings: 60%, 80%, and 100%, corresponding to average irradiance levels of 525.67 W/m², 694.22 W/m², and 741.00 W/m², respectively. For each setting, power density values were recorded at six measurement points and three measurement rows to characterize the non-uniform irradiance distribution across the test surface. The dataset also includes numerical–experimental comparison data for PV surface temperature at different mass flow rates ranging from 0.01 to 0.07 kg/s. Experimental and simulated PV surface temperatures are provided for the three irradiance levels, together with percentage error values used for model validation. Additional thermal performance data include PV surface temperature dependence on mass flow rate, inlet and outlet water temperatures, and outlet temperature variation under different irradiance conditions. Electrical performance data are also provided, including current–voltage (I–V) and power–voltage (P–V) curve data at different mass flow rates for the three irradiance levels. The dataset includes voltage, current, and power values used to evaluate the electrical response of the PVT system. Maximum power output values are reported for each mass flow rate and irradiance condition. The dataset further contains calculated thermal efficiency, PV electrical efficiency, and total PVT efficiency as functions of mass flow rate under irradiance levels of 525.67 W/m², 694.22 W/m², and 741.00 W/m². These data support the figures, tables, validation results, and performance analysis presented in the manuscript.
