Análise de um coletor solar para piscina através de simulação computacional

Abstract

This work deals with the use of clean solar energy for a water heating system for a specific swimming pool, located in the city of Dourados, in the South-central region of Mato Grosso do Sul state, with the objective of analyzing the behavior of water: observing its temperature, pressure, velocity and pressure drop. Firstly, the catalytic analyzes of the solar collector manufacturers were done, estimating the quantity of 19 collector plates and the flow rate of 4500 liters per hour for the system. After this information was assembled, the conditions were simulated in the software ANSYS FLUENT to search the behavior of the fluid during the pool-heating process. Afterwards, it compared the results with those of the manufacturers, resulting in a temperature increase of up to 0.3 K per solar collector, being sucient for the heating of the pool and the insignicant loss of charge in the pipe of the collectors. By the end, it was verified possible forms to improve this system in the future.
