The impact of design parameters on the cooling performance of TABS

Abstract

The paper highlights the influence of design parameters, such as pipe spacing, pipe diameter, type of floor covering, fluid flow regime, and fluid flow temperature on the cooling performance of thermally activated building systems (TABS). Considering the existing TABS developed in the Radiant Surface Laboratory of the Civil Engineering Faculty of Brasov as a model a study based on a commercial simulation program (Comsol Multiphysics) was carried out. COMSOL Multiphysics® is a general-purpose software platform, based on advanced numerical methods, for modeling and simulating physics-based problems. With COMSOL Multiphysics, you will be able to account for coupled or multiphysics phenomena. The COMSOL Desktop® is a powerful integrated environment designed for cross-disciplinary product development with a unified workflow, regardless of the application area [7]. The results of the simulation and the conclusions are presented.
