In the present study, the heat transfer, moisture distribution, air flow and thermal comfort in a residual room
which is warmed by convectional thermal panels under different environmental conditions was assessed
numerically. The analyzed model is the real and dynamic 3D simulation, and a virtual thermal manikin with real
physiological dimensions has been added to the model. The manikin is standing at the center of room. The room
has dimensions of 3*4*4 m with an inlet device that has dimensions of 1.28*0.054
2 m and two outlet devices
with dimensions of 0.054*1.02
2 m . The inlet and outlet devices have been modeled above and under the door.
To determine the optimal arrangement and number of panels, three models have been studied. The models
include one panel with real dimensions of 1.242*0.81
2 m , two panels with real dimensions 0.61*0.96
2 m and
three panels with real dimensions 0.61*0.81 2 m , with a thickness of 20cm in all panels. The uniform
distribution of temperature, velocity and moisture, and proper and symmetric arrangement of panels, inlets and
outlets decrease the energy consumption and satisfy the thermal comfort of inhabitants. Thermal loss increases
due to the panels under the window. It was concluded that using two panels with smaller dimensions at the left
and right of the model instead of one panel under the window or three panels at the left, right and under the
window significantly reduces the thermal loss.
