Original Abstract
There is a problem with condensation in the ice stadiums caused by radiation of ice surface – this has been confirmed theoretically, experimentally and empirically. Our contribution deals with the theoretical-experimental analysis of selected measurements for prevention of condensation. We focused on air ventilation precautions. Our research is based on the assumption that higher velocity and temperature of airflow and better position of air outlets may reduce risk of condensation. Theoretical solution applies CFD simulation method of heat transmission by convection, conduction and radiation in 3D space. The results we obtained by CFD simulations are validated by experiments. The obtained results confirm the ability of ventilation system to eliminate the condensation, although at high operating and capital costs. Suspended ceiling under the roof has been identified as the optimal solution application of low-emissivity.
