Abstract


Conventional sources of energy are rapidly decreasing more and more. Hence, Renewable energy is presently attracting significant. Therefore, this paper aims at investigating the techno-economic feasibility of SWHS for swimming pools in tourist hotels and resorts. The proposed system presents an active direct system without auxiliary heaters to evaluate the potential for using solar thermal collectors for heating swimming pools of tourist resort; installed in El Gouna city, Egypt, 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 concerning system cost, system yield and economic values and then carried out experimentally. The simulation results showed that the installed collector power of SWHS is 9,980kW and solar energy contribution to the swimming pool is 25.831MWh. The system efficiency is 75.5% and the 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. When taking into account the cost of CO2 emissions, the proposed system avoided 6,720kg annually resulting in saving 6102$. The experimental results illustrated that system sizing is 28 of solar absorber collector and 1hp pool pump. System cost and COE of the system are 8251.37$, 0.0095$/kWh respectively. The cost of one liter of water heated is 0.387$ and the payback period is 14 months. For a multitude of reasons, solar water heating for hotels and resorts is an ideal choice.
