A Dynamic Simulation Model of Outdoor Swimming Pool with Thermal Energy Storage, Boiler and Solar Thermal Collectors

Abstract

Outdoor swimming pool facilities are significant energyconsumers, primarily due to the need to maintain thermalcomfort for swimmers, as the pool is exposed to wind andoutdoor air. To address thechallenge of reducing energy consumption, effectivesimulation of the dynamical system is essential to identifyenergy-saving solutions. This paper presents acomprehensive implementation of an outdoor swimming poolsimulation model using the Modelica programming language.The simulation model also incorporates a thermal storagesystem, a boiler, and a solar thermal collector, allowing adetailed analysis of the system. In addition, an in-depthexplanation of the physical equationsgoverning the swimming pool is provided, along with themethodology used to construct theModelica model. The results show that the model allows thesimulation of the thermal behavior of an outdoor swimmingpool, including various heat losses, solar heatgains, and heat production from the boiler and solarcollectors.
