Monitoring and Measurement of Thermal Performance of Solar Heated Outdoor Swimming Pools With Different Covers

A comparative analysis of the performances of three outdoor swimming pools for private use with different types of covers is presented in this paper. They are designed to take advantage of solar irradiation to maintain the swimming pool temperature within certain acceptable limits, so that the swimming pool can be used during most of the year under South-Europe climatic conditions. In this region, the annual global irradiation is of the order of 1800 kWh/m² and air temperature is in the range from 0°C to 40°C during the whole year. No auxiliary boosting is used to heat the swimming pools.
