Thermal Performance of Hybrid Solar Swimming Pool and Heating of Building in Kirkuk City-Iraq

Year: 2025

Type: article

Abstract: 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.
