Sažetak
A novel hybrid cooling strategy was proposed for the free-standing photovoltaic panel (PV), i.e. the design of a novel photovoltaic- thermal collector (PVT) was proposed. The hybrid cooling approach assumes both passive (PCM-Phase Change Material) and active (water) cooling approach with an incorporated smart regulation system. The design details of a novel hybrid cooling approach, i.e. novel PVT collector were elaborated in detail. Besides elaboration of the specific design approach, the experimental and numerical investigation was also carried out as a necessary step for further development of the ongoing experimental setup. Namely, the convective heat transfer coefficients were investigated by experimental way. The idea was also to investigate a general behaviour of the convective heat transfer profiles for various wind speeds (0 m/s to 6.7 m/s), relative wind angles (0° to 45°), and PV panel tilt angles (0° to 35°) since they strongly affect performance. The numerical analysis was conducted, and simulations were compared with experimental readings. An average deviation between the measurement and experimental data was determined to be around 12%. The proposed concept of a novel PVT collector could be suitable for building applications as an integral part of the building energy systems, i.e. for space heating.
