Thermal Performance of Single Glazing Flat Plate Photovoltaic Thermal Hybrid System with Various Air Channels

Abstract

The present study attempts to investigate the thermal performance of five types of mild steel air channels in the photovoltaic thermal hybrid system. This system has been designed, fabricated, and tested in the tropical climatic condition of Chennai, India. There are five kinds of air channels studied in this work, namely, reference air channel, single-fin channel, multifin channel, fin with T baffle channel, and fin with V baffle channel. These channels are studied and compared. The experiments were accomplished with two mass flow rates, m˙: 0.00565 and 0.00847 kg/s. The photovoltaic thermal hybrid system performance was enhanced by increased air velocity, enhanced heat transfer between the absorber surface and air, and physical geometry of the channel. This optimal performance has been attained in the present study, with strong agreement with previously published findings. The photovoltaic thermal hybrid system experimentally proved to enhance thermal and photovoltaic efficiencies with increasing air mass flow rate, and the maximum electrical efficiency was found to be 13.70 % at the mass flow rate of 0.00565 kg/s and 14.27 % at the mass flow rate of 0.00847 kg/s; similarly, the thermal efficiency was 14.12 % at m˙ = 0.00565 kg/s and 20.81 % at m˙ = 0.00847 kg/s.

Modelling and Optimization of Photovoltaic Serpentine Type Thermal Solar Collector With Thermal Energy Storage System For Hot Water and Electricity Generation For Single Residential Building

“…Solar energy is typically used to generate heat energy and electric energy using thermal collectors and PV systems. While the use of solar energy has grown, some limitations, such as high installation costs (Fakouriyan et al, 2019;Srimanickam et al, 2015), low energy conversion e ciency (Srimanickam et al, 2017;Srimanickam and Saranya, 2021) and the need for storage systems due to supply and demand curves that differ (S. Thakur et al, 2020) have a negative impact on its use in comparison to other renewable energy sources. An enormous amount of research articles on photovoltaic/thermal (PV/T) technologies have been published in an attempt to resolve the above said barriers (Giwa et al, 2020;Lamnatou et al, 2021;Reji Kumar et al, 2020).…”
