Feasibility of a solar swimming pool in the western part of Romania

We propose a framework for calculation of the energy balance of an outdoor swimming pool intended for potential users of solar energy in the region of Timisoara, Romania. The algorithm is based on physical and practical considerations, on existing experience in the field and on measurements of solar radiation. According to the calculations, a solar swimming pool with an area of 160 m² has energy losses of 564.02 GJ and it receives 336.69 GJ of energy in passive mode from solar radiation in the period April-September. A proposed solar system with a collecting area of 81 m² provides 119.36 GJ of thermal energy in the same period. A quantity of 107.97 GJ has to be supplied from classical sources.
