Abstract text:
The paper presents the results of the numerical research carried out on a thermal storage module equipped with fascicle geoschimbers, working with nanofluid. The original design solution is designed for seasonal heat storage in heating / air conditioning systems for buildings and shows interest in superior energy efficiency compared to classical solutions. The study is carried out with the purpose of capitalizing the results for the realization of variable geometry modular geothermal heat exchangers. The advantage of the modular concept consists in increasing the energy efficiency and uniformity of the heat flow, ie the demand of the storage mass, by the dimensioning of the heat transfer surface inversely proportional to the temperature difference between the fluid and the solid. The use of nanofluids as a calizo agent is justified by the superior thermophysical performance of water, used in classical solutions.
