The master’s thesis at the Engineering Technical College of Kirkuk examined the selection of an optimal hybrid voltaic thermal system between a system containing a phase-changing material and another operating using a nanofluid.
The thesis presented by the student, Murad Ahmed Fakhreddin, dealt with the study of choosing the optimal hybrid voltaic thermal system between a system containing a phase-changing material and another operating using a nanofluid.
This thesis aims to design and build a photovoltaic (PV) panel and two thermoelectric collectors, one of which is a conventional thermoelectric collector (PVPT) and the other contains a layer of paraffin wax (WPVT). The photovoltaic panels used are similar in terms of technical specifications, material, and generating capacity. The same encapsulation process was carried out but the exchanger was completely immersed in a layer of wax before applying the glass wool. Tests were conducted on this system for two consecutive months (April and May 2022) in the city of Kirkuk. The tests in April included the use of normal water in the two complexes as a working fluid and with a flow rate of LPM (0.5, 1.0, 1.5), while the tests in May replaced the water in the conventional complex with a fluid. Nano (Al2O3, 1%wt – Water) and symbolized by (TPVTN), and the tests continued at the same flow rates. Through the results of practical tests, the researcher concluded that the thermal performance of the collector (WPVT) was better in the three flow rates than each of (TPVT and TPVTN), so that its improvement rate ranged from 60% to 2.9 times compared to the (TPVT) complex. (42 to 61)% compared to the compound (TPVTN). The use of nanofluid in the conventional collector instead of water increased its thermal performance by (52, 61, 42) % for the flow rates of (1.5, 1.0, and 0.5) LPM, respectively.
