Study of the Application Characteristics of Photovoltaic-Thermoelectric Radiant Windows

Through experiments and numerical simulation, this paper studies the related performance of a photovoltaic thermoelectric radiation cooling window structure, verifies the accuracy of the established solar thermoelectric radiation window calculation model, and analyzes the cooling performance of different parameters of thermoelectric sheet, radiation plate, and photovoltaic panel. On the basis of considering the relationship between the power generation and power consumption of the structure, the numerical calculation results show that the solar thermoelectric radiation window with non-transparent photovoltaic module (NTPV) has a total cooling capacity of 50.2 kWh, power consumption of 71.8 kWh, and power generation of 83.9 kWh from June to August. The solar thermoelectric radiation window with translucent photovoltaic module (STPV) has a total cooling capacity of 50.7 kWh, power consumption of 71.7 kWh, and power generation of 45.4 kWh from June to August. If the operation time of the thermoelectric module is limited, when the daily operation time of TEM is less than 8 h, the power generation of STPV can meet the power consumption demand of the thermoelectric radiation window from June to August.

Automated summary

Through experiments and numerical simulations, this study verifies the accuracy of the established calculation model for a photovoltaic thermoelectric radiation cooling window structure and analyzes the cooling performance under different parameters. The results show that the solar thermoelectric radiation window with NTPV and STPV have different cooling, power consumption, and power generation capacities in the summer, and when the operation time of the thermoelectric module is limited, STPV can meet the power generation demand of the window.
