Determining the performance of chilled ceiling systems through simulation

Ke Kelit GmbH is a manufacturer of surface heating and cooling systems. The optimisation of ceiling cooling systems is a decisive factor for the market success of a system. In order to be able to estimate the efficiency of optimisation measures, the heat transfer performance was examined using a 2D simulation. The performance was compared with an existing variant. This meant that validation in a test was not necessary. To determine the performance data for heating and cooling in advance, 4 different variants were analysed with regard to the cooling and heating performance data using a numerical 2D simulation using CFD. These were classic cooling ceiling systems with plasterboard and metal ceiling systems.
