Solar Energy System for Heating Swimming Pool

The proposed solar heating system supplies an outdoor swimming pool of touristic resort; installed in El Gouna city, Egypt. The proposed system presents an active direct system without auxiliary heaters to evaluate the potential for using solar thermal collectors for heating swimming pools and to size solar collector using TSOL simulation software package to meet the demand of hot water, to analyze the impact of collector design-parameters with respect to system cost, system yield and economic values and then carried out experimentally. The volume water required to cover the pool load pattern is 136 liter per day. Four metrics are adopted to appraise/measure system economy: net present value, cost of energy, cost of water heated and payback period. The simulation results showed that the installed collector power of SWHS is 9,980kW and solar energy contribution to swimming pool is 25.831MWh. The system efficiency is 75.5% and annual solar yield obtained is 2153kWh/year. For the economic side, NPV and COE are 5878.37$, 0.0045$/kWh respectively. Plus, the payback period of this proposed system is 18 months.
