A numerical analysis of heat and mass transfer in a room with the air-underfloor heating

The current work presents features of an air-underfloor heating system and CFD model to predict velocity and temperature distribution. The paper describes the constructions of air-underfloor heat exchangers. Computational fluid dynamics professional software-ANSYS/FLOTRAN was used to simulate of turbulent airflow and radiation heat transfer in ventilated room with air-underfloor heating installation. The numerical simulation of many cases was performed to study the comfort criteria in the tested room.
