Experimental and Numerical Analysis of Heating Performance of a New Skirting Board Radiator with Forced Air Circulation

The thermal performance of a new modified hydronic skirting board heating system with an air supply is investigated in the present work. In the modified system indoor airflow is forced through a duct that is located between the systems. The main aim of the present work is to achieve a system with higher efficiency and lower energy consumption than conventional cases. The heat output rate of the system is evaluated experimentally for different water flow rates and inlet water temperatures based on standard No. En-442. A comparison of the results between the new system and the conventional models shows that heating performance improved by about 23%. Thermal comfort conditions in the room are analyzed according to Fanger's method and results show that people's dissatisfaction (PDD) in the different parts of the room is less than 40%. Also to validation of the numerical results, the temperature distribution of the simulation is compared with experimental data and obtained results show that there is a good agreement between them.
