A system to monitor and model the thermal isolation of coating compounds applied to closed spaces

Abstract

Original scientific paper https://doi.org/10.2298/TSCI190525077M Smart control systems and new technologies are necessary to reduce the energy consumption in buildings while achieving thermal comfort. In this work, we monitor the thermal evolution inside a scale reduced closed space whose exterior and/ or interior wall faces have been painted with a coating solution. Based on the experimental data obtained under different environmental conditions, a simulator was developed and tuned to reproduce the thermodynamic behavior inside the spaces, with a relative error of less than 3.5%. This simulator lets us also estimate energy savings, temperature, and flux behavior under other conditions.

Passive Strategies to Improve the Comfort Conditions in a Geodesic Dome

“…This is the case with the new thermal coating being tested in reduced scale models at the Universitat Politècnica de València, Spain. The study yielded reductions of interior temperatures by 7.4% [25].…”

“…The procedure for adjustion consists in separating the studied period in the day and night and calculating the best value to fit the simulation curves to the experimental data. This method has been tested in similar investigations [25,47].…”

“…The first effort to minimize the cooling requirements was based on apply coating solutions over exterior surfaces. In [25] an experiment was developed to determine the thermal properties of a commercial coating solution. One of the results of this study was the convection coefficient of a surface with a layer of coating solution with a thickness of 0.5 mm.…”
