Feasibility Study of Using Solar Thermal Energy for Heating Swimming Pools in Central European Climate (Hungary as a Case Study)

Heating swimming pools using electrical elements is costly and causes environmental impact by producing CO2 emissions. While renewable energy, such as solar proves a viable alternative source for pool heating. This article aims to simulate various Solar Domestic Hot Water (SDHW) systems in cold climates like Central European countries define the best system Three different were compared: heating without auxiliary or heat exchanger (B6), with (B6.1) an (B6.2). Also, five crucial variables chosen, along variation of other parameters response surface method (RSM). optimisation optimal less financial expenditure. It was found that B6, represented Experiment No 25, which indicates Collector type: flat plate collector (FPC), depth: 1 m, temperature: 26 ℃, covers, windshield are actively operated. We used T*SOL Valentine Software-2018 (kWh) measure contribution each case. For vector, our coded values range from [-1, +1]. The formula 2k (25=32 experiments) defines number experiments, where k vector number. In addition, two more experiments done second-degree non-linear coefficients depth (B) 1.5 m 28 ℃ temperature. These additional however, had no on results. Finally, suitable this weather compared. experiment can help locals find their pools.
