Introduction and Literature Review of the Application of Hydronic-Based Radiant Cooling Systems in Sustainable Buildings

Hydronic-based radiant cooling systems have been widely utilized for their energy efficiency and offering more thermal comfort for occupants when compared to conventional convection-based cooling systems. However, the potential risk of developing condensation on the surface keeps thermo-active building systems (TABS) from being applied in buildings located in warm and humid climate regions. This chapter presents a model predictive control (MPC)-based condensation prevention approach that allows the prevention of surface condensation during the cooling periods when the TABS is in operation. Based on future conditions predicted by the dynamic models, the MPC-based condensation prevention framework adjusts the surface temperature for the TABS in ways that guarantee occupant thermal comfort and energy efficiency without the development of surface condensation.
