“…Comparison of the testing results with Wang et al 19 Wang et al 19 designed the metal-wires-based-BIPV/T system with the conventional finned heat pipes as shown in Figure 20. The only difference between the two systems was that the micro-channel flat-plate heat pipes of the proposed system replaced the conventional heat pipes of the metal-wires-based-BIPV/T system.…”

“…Moradgholi et al 18 investigated the performance of the thermosiphon-type heat-pipe PV/T system with different working fluids in both spring and summer seasons. Wang et al 19 investigated the conventional finned heat pipes BIPV/T system with the metal wires filling into the space between the PV panel and heat pipes, and found that the maximum thermal efficiency and electrical efficiency of the system were at 44.04% and 7.9%, respectively.…”

In this paper, the micro-channel flat-plate heat pipes-based BIPV/T system has been proposed, which is expected to have the characteristics, e.g. reduced contact thermal resistance, enhanced heat transfer area, improved heat transfer efficiency and building integration. The proposed system was constructed at the laboratory of Guangdong University of Technology (China) to study its performance. The temperatures of the glass cover, PV panel, micro-channel flat-plate heat pipes, and tank water were measured, as well as the ambient temperature. The thermal and electrical efficiency was also calculated for the system operated under the conditions with different simulated radiations and water flow rates. It was found that the proposed system can achieve the maximum average overall efficiency of 50.4% (thermal efficiency of 45.9% and electrical efficiency of 4.5%) for the simulated radiation of 300 W/m2 and water flow rate of 600 L/h. By comparing the proposed system with the two previous systems employing the conventional heat pipes, the thermal efficiency of the proposed system was clearly improved. The research will develop an innovative BIPV/T technology possessing high thermal conduction capability and high thermal efficiency compared with the conventional BIPV/T system, and helps realise the global targets of reducing carbon emission and saving primary energy in buildings. Practical application: This novel BIPV/T employing micro-channel flat-plate heat pipes will be potentially used in buildings to provide amount of electricity and thermal energy. The generated electricity will be used by the residents for electrical devices, and the thermal energy can be used for hot water, even for space heating and cooling.

The paper presents the analysis of the cooling of a photovoltaic (PV) panel integrated on the facade of buildings, in vertical position, for different orientations: South, SouthEast and SouthWest. The effect of the cooling of PV panel is presented comparatively for the basic case, the case of the PV location apparently on the building facade, without the possibility of ventilation on its rear area and also for the integration in the ventilated facade of the building. Finally, the optimal solutions for obtaining passive cooling by using air and heat sinks or active cooling by using water film exchanger are evaluated. The study aims to evaluate the efficiency of PV panels according to climatic conditions and does not concern the operation of the entire photovoltaic system.

The hybrid photovoltaic-thermal system has shown great progress. Electrical energy is produced from PV panels while thermal energy is produced via a working fluid carried through the panels. In this paper, the vertical PV/T is introduced using working fluids such as air and liquid, which serve to control the excess temperature of the PV panels as well as to collect heat to be made available as thermal energy. Installations of PV/T systems on building façades, as well as integration with other technologies such as heat pipe and heat pump are also discussed. Current studies of such building integration technologies are also explored, including the scale of application. This study aims to provide constructive information which can be used in future development of building facades for large-scale applications, to contribute to future sustainable development. Practical application: This study helps researchers and engineers who are considering photovoltaic thermal systems for building façades to have better understanding of its effect on electrical and thermal energy – for space heating, fresh air supply and hot water supply – using an active building envelope.
