“…On the other hand, when the mass flow rate rises from 0.04 kg/s to 0.2 kg/s an increase in efficiency from 0.34 to 0.46 occurs, while (T out − T in ) decreases from 7.45 to 1.99 • C (Figure 10). The opposite trend between heat transfer and efficiency obtained is similar to results achieved by equivalent studies [4,33,34]. The main consequence of this situation is that, for high flow rates, the heat transfer is lower because the temperature increase in the fluid outlet is less pronounced since the conduction effect is more limited.…”

The building sector presents poor performance in terms of energy efficiency and is looking for effective alternatives aimed at reducing the use of fossil fuels. The facade is a key element able to harness renewable energy as an Active Solar Thermal Facade (ASTF). The main purpose of this study is the assessment of a novel design concept based on a steel sandwich panel technology. The performance of the active system will be first addressed by a parametric study in order to analyze its behavior and secondly, by describing a real case based on an experimental test by connecting the active panels to a heat pump. The study shows the impact of solar irradiation and mass flow on the thermal jump achieved, while ambient and fluid inlet temperatures are the most influencing parameters in the efficiency of the facade. When coupled to the heat pump, results from a measurement campaign demonstrate a remarkable improvement in the performance of the ASTF. The results presented provide significant proof about the benefits of a synergetic combination of both technologies—solar facades and heat pumps—as efficient alternatives for the building sector, aiming to improve energy efficiency as well as reduce their dependence on non-renewable sources.

“…They also investigated the effects of inlet temperature and incidence alngle on collector parameters. Chen et al [9] carried out tests to evaluate the efficiencies of two solar FPCs at different flow rates. Sakhrieh and Al-Ghandoor [10] conducted an experimental study to characterise the overall performance of four types of FPCs and an evacuated tube collector used in Jordan.…”

“…The selective coating of the adsorber plates with materials of high absorptance is reported in [4] ; use of nano copper oxide and nano titanium dioxide as selective coating material is discussed in [5] and the effect of water based Al 2 O 3 nanofluid is presented in [6]. The black paint embedded with a nickel-aluminium metallic particle results an improvement of about 5 C comparing with non-embedded paint [7].…”

Solar flat plate collectors nowadays find more applications considering the cost involved with conventional water heating systems using fossil fuels. The performance of these systems can usually be enhanced by varying select important parameters of the system for improved heat transfer ability of the collector. Therefore, this work is aimed at evaluating the effects of nano-Nickel Oxide (NiO) coatings on liquid flat plate collector for better heat transfer effect. Two flat plate collectors are designed and fabricated with same operating parameters such as collector area, system size and spacing, pipe diameter and size of collecting tank, etc. The heat transfer effect is simultaneously studied in these two units to observe the effect of nano coating in comparison with black chrome coating
