Numerical simulation of radiant ceiling panels for indoor cooling

[摘要] The aim of this work is to analyse the thermal performance in cooling of two different models of radiative ceiling panels, by varying the discharge temperature and the velocity of heatcarrying fluid. The first one geometrical configuration refers to a coil- embedded panel, while the second one is made by a matrix of tubes. Numerical simulations were carried-out by using a FE-approach to solve governing equations for the physical system. Thermal performances were analysed as a function of the inlet temperature and the inlet velocity of the fluid. Then interpolation functions are proposed in order to assess thermal performances for both geometrical configurations against several working conditions.
