“…Double glass-acrylic-covered SAHs showed comparable daily thermal performance and enhanced durability. Rashid et al 11 studied enhancing tilt angle and heat transfer efficiency of an active flat plate solar collector using MATLAB software. Data showed a peak efficiency of 77% with an optimal heat rate of 975 W and 64°C output water temperature.…”

A hybrid flat solar collector was manufactured from basic materials to combine the effects of both water and air solar heaters. The reason is to increase the amount of heat delivered to water by doubling the heat sources, one from the direct beam of sun and the other from the hot air delivered by the air solar heater. In addition, the flow of water inside the solar heater is made in a thin layer so that much heat can be gained by water per unit time. The outlet hot air of the solar air heater enters air ducts that pass through the solar water heater. With a constant water flowrate of 0.0167 kg/s, three different air velocities (1.7, 2.1, and 2.4 m/s) were applied to determine the optimum air velocity that results in the maximum outlet water temperature and the maximum removal factor FR for the solar water heater. The experiment was run from 10:00 a.m. to 2:00 p.m. every day during June 2023 and the data was recorded every 15 min. The data obtained from the experiment showed that the lowest air speed (1.7 m/s) results in the highest outlet water temperature (63°C) and heat removal factor FR (0.74).

This research aims to investigate the performance solar water collector by varing five parameters; which are mass flowrate, inclination angle, total solar radiation, pipe size, and number of glass covers. The test rig was established to collect the data for the whole months of September and October and use it as a focal point for analysis of the solar water heating system's performance. The dynamic behavior simulated and optimizated with MATLAB software for the practical data to investigate the performance of the flat plate solar collector. The novelity in this study is the first time the authors use the whole practical data instead of using an average to approximate the theoretical dynamic investigation of the flat plate solar collector. The achievements are as follows: The increase in collector efficiency was from 62.17% to 71.26% when the collector pipe spacing was reduced from 186 mm to 86 mm; the increase in efficiency was approximately 2% as the collector pipeline diameter grew from 1 mm to 50 mm; the optimum efficiency was achieved with triple glazing and was about 0.83%; the increase in mass flowrate from; 1 to 5 liters per minute, would improve the efficiency of the system from 64% to 83%. Moreover, the best tilt angle for the flat plate solar collector was 30°.Also, heat loss coefficient rises by around 50% when wind speed is increased from 1 m/s to 5 m/s. Thus, the use of dynamic investigation with actual data will assist the researcher in improving the performance of the solar water flat plate collector.

“…showed that dust and dirt could significantly contribute to reducing the solar reflectivity of the RCM. Singh and Rawat [21] highlight the thermal performance of cool roofs with various surface coatings in different climate zones for buildings, along with additional advantages, limitations, and recommendations for further study. The average energy-saving impact of the roof varies by climate zone and ranges from 15% to 35.7%, according to the literature review findings (Composite, Temperate, Tropical, Hot, and Warm-Humid).…”

The thermal performance of a concrete roof between the main slab (concrete slab) and secondary slab (gypsum board) has been investigated in this work with and without a ventilator. The hourly averaged climatic data (combined optical and thermal condition) of the external roof surface was used as the resource for the boundary conditions of Erbil city (Kurdistan Region, Iraq). The results of measuring the effects of using a ventilator between the concrete slabs and gypsum boards indicated that the moving air in the layer between slabs by using the ventilation process has more effect in cooling roofs and the room temperature had less than that of slabs that do not use ventilation, and so using baffle shape gypsum board as the secondary slabs for air turbulence to increase air velocity, the number of mass flow rates have more efficient in the cooling process and fast the cooling process, the surface temperature was reduced by (4.5oC and 3.6 oC) with the mass flow rates of (3.5kg/s) and (2kg/s) respectively, this is due to moving air makes roof slab cool and loss the heat that transfers through the slabs, so using this technique for an exciting roof is a good choice
