Use of an Outdoor Swimming Pool as Seasonal Heat Source in Heat Pump Applications

The improvement of energy efficiency in the building sector is one of the most promising actions for achieving the energy and environmental goals of the European Community. The deep retrofit of buildings is obviously the best solution in terms of energy performance result. When the deep retrofit is not allowed or possible, the simple maintenance of the building envelope and plant is usually done to assure the operation over time. This type of intervention could require the installation of new HVAC systems that could include a HP, which nowadays represents one of the key devices for the energy saving and the sustainable development. This work regards the study of the energy performance of a swimming Pool Centre in North-East Italy. The objective of this work is the exploitation of an outdoor swimming pool as a heat source for a HP system. The HP system uses two different heat sources, the air and the water. The final SCOP of the double source HP system has been calculated and compared with an air source HP solution. This analysis has been carried out by means of dynamic energy simulations in TRNSYS environment.
