Abstract |
It is necessary to know convective heat transfer coefficient at each part of human body to evaluate indoor thermal environment. The present paper studies the natural convection around human body at floor heating system by using a thermal rectangular hexahedral manikin. The convective heat transfer coefficient was estimated from the surface temperature of various locations on the manikin. A steep change with the height was found in the convective heat transfer coefficient along the leg part. The highest convective heat transfer coefficient was found at the lowest temperature measuring point on the leg part. The average heat transfer coefficient over the manikin was 3.2W/m2K at front part and 4.0W/m2K at side part of the manikin. It will be necessary to consider the change of convective heat transfer coefficient with the positions of human body when appropriate floor temperature at floor heating system is decided. |
