Abstract
This paper aims to improve the performance of a bi-fluid PV/TW system by fixing a glass cover on the front of a solar cell and inserting a porous medium within the air duct. Moreover, the influence of the DC fan and water flow rate through the cooling circuit was investigated. For this purpose, two experimental models of the bi-fluid PV/TW system were built up and tested under various operating conditions. The acquired results revealed that the room and solar cell temperatures were higher for the glazed configuration of the bi-fluid PV/TW system compared to the unglazed configuration. This is a favorable outcome for building conditioning in cold weather; however, it is an undesired consequence in terms of electricity generation. In addition, the presence of the glass cover leads to an increase in thermal efficiency and decreases electrical efficiency due to an increase in the temperature of the solar cell. It is also realized that an increase in water flow rate and using DC fan lead to increase thermal and electrical efficiencies. The maximum values of thermal and electrical efficiencies were 76.76% and 13.69% for the glazed and unglazed models, respectively, with porous medium and DC fan at 300 liters/day of cooling water discharge. While the maximum value of total efficiency was 87.44% for the glazed model, with porous medium and DC fan at 300 liters/day of cooling water discharge.
