Thermal Performance of Hybrid Solar Swimming Pool and Heating of Building in Kirkuk City-Iraq Eman A. Allaw, Fayadh M. Abed, Hussein Hayder Mohammed Ali Tikrit Journal of Engineering Sciences, 2025 In the latest development, a solar hybrid system maintains the outdoor pool at a constant 30°C year-round. Solar energy, a crucial renewable energy source, is harnessed through a novel collector design emphasizing the importance of tourism designs and heating concepts with environmental considerations. The technology, widely used in homes, involves measuring unglazed flat solar collectors (3.12 m2) for outdoor dome swimming pools in winter. A 2 m2- collector was integrated into a building and studied for seven daily hours over three months (December, January, and February). The internal heating system relied on a fan for electrical energy, reaching peak efficiency in February. Operating at 700 W/m2 radiation intensity and a 0.16 kg/sec flow rate, parameters such as sun intensity, ambient temperature, pond water conditions, solar output, water flow, and humidity were recorded. Thermal losses from the pool were calculated using a flat, oval-shaped tube solar collector, along with the room temperature after the pool had stabilized. The results showed a 0.16 kg/s flow rate optimized collector efficiency, prioritizing these findings for achieving thermal comfort, effective building heating, and preserving indoor pool temperature.
Experimental and Theoretical Study of Parabolic Trough Solar Collector Performance Without Automatic Tracking System Khudir Zidane Zarrag, Fayadh M. Abed, Salim. Y. Kasim Journal of University of Anbar for Pure Science, 2021 at noon. The large deviation value mentioned resulting from the assumptions that have been developed to simplify the equations that were used in the theoretical side of research, also the reasons that the theoretical results are taken on the assumption that weather conditions are clear sky and that contrary to reality in the winter. جThe best efficiency of the solar collector was between solar time (12:00) and time (1:00) at night for two seasons, and the obtained results showed that the increase of mass flow rate of fluid from the amount of (0.033) kg/sec to the amount of (0.066) kg/sec increases the efficiency of solar collector, but leads to reduce the temperature difference between the inlet and exit, as well as the results showed that an increase in solar flux increases the useful energy obtained from the solar collector.
