In this work, the authors realize a simulation in Comsol Multiphysics of a swimming pool with a cubature of 495m3 at a temperature of 27 °C, where it is searched as principal objective to see the homogenization of the water temperature in its volume in function of the geometric characteristics of the swimming pool, the localization of the points of discharge and suction of the water and the environmental conditions. To make the simulation, it will do during the period of time available a series of measurements thermo-fluidics that contains temperatures, flow of water to the inlet of the swimming pool, power of the pump of the system of filter, between others, with the purpose of obtaining a result near to the reality. The Second objective of this simulation is to present different positional configuration of the points the discharge and suction which bring to a better homogenization of temperature in the water. This tool will allow designers and builders of swimming pools, set the suction and discharge systems, in such a way that allows adequate homogenization of the temperature with minimal energy consumption.
