SOLAR SWIMMING POOL HEATING - DESCRIPTION OF A VALIDATED MODEL

In the framework of a European Demonstration Programme, co-financed by CEC and national bodies, a model was elaborated and validated for open-air swimming pools having a minimal surface of 100 m2 and a minimal depth of 0.5 m. The model consists of two parts, the energy balance of the pool and the solar plant. The theoretical background of the energy balance of an open-air swimming pool was found to be poor. Special monitoring campaigns were used to validate the dynamic model using mathematical parameter identification methods. The final model was simplified in order to shorten calculation time and to improve the user-friendliness by reducing the input values to the most important ones. The programme is commercially available. However, it requires the hourly meteorological data of a test reference year (TRY) as an input. The users are mainly designing engineers.
