Experimental and Numerical Evaluation and Comparison of the Performance of Baseboard and Panel Radiators

In this paper, experimental and numerical comparison of Baseboard radiator and Panel radiator are presented. Rated capacity of both radiators was 1200 kcal per hour. In the experimental section, at the same ambient temperature for both radiators, capacity and characteristic equation and temperature distribution in a room with dimensions of 2.6 × 4 × 4 meter was obtained. The experimental results showed that a Uniform Temperature distribution occurs in the room for the Baseboard radiator, Temperature difference in vertical direction for center of the room for the Panel radiator in various capacities changes 3°C to 7°C, While for the Baseboard radiator at all capacities temperature difference was about 2 °C. Temperature difference at height of 1.5 m in horizontal direction from wall that the Panel radiator was installed to facing wall, changes 3°C to 6°C. While for the Baseboard radiator, this result was about 0.5°C. To investigate the cause of the temperature distribution, numerical modeling was used. Numerical results and experimental results were close with 10% error. Temperature distribution curves At plane of symmetry room for both samples was drawn, Baseboard radiators were more uniform temperature distribution again. In the end, the velocity distribution diagram in the vertical plane of symmetry room was obtained which show that a strong circulation occurs in the room for the Baseboard radiator.
