Numerical Analysis on the Performance of a Radiant Cooling Panel with Serpentine-Based Design

Radiant cooling systems (RCS) are gaining acceptance as a heating, ventilation, and air conditioning (HVAC) solution for achieving adequate thermal comfort maintaining acceptable indoor quality inside buildings. RCS well known their energy-saving potential; however, serious condensation problem hinders the growth of this technology. In order to prevent risk condensation, supply water temperature is kept higher than dew point room. The full potential power radiant panel limited. Therefore, article on maximizing capacity panel, in terms flow configuration. panels (RCP) with different chilled pipe configurations designed compared, side by conventional serpentine performance evaluated using computational fluid dynamics (CFD) Ansys Fluent software (Ansys 2020 R2, PA, USA). Under similar operating conditions, common configuration exhibits least effective performance, highest pressure drop across pipe. It concluded that proposed designs have improving overall efficiency RCP distribution, capacity, drop.
