A virtual sitting manikin with real dimensions and physiological shape was added to the model of Received in revised form 11 July 2010 the room, and it was assumed that the manikin surfaces were subjected to constant temperature. Two Accepted 31 August 2010 different heat transfer coefficients for the outer wall and for the window were considered. Heat interac- tions between the human body surfaces and the room environment, the air flow, the temperature, the Keywords: humidity, and the local heat transfer characteristics of the manikin and the room surfaces were com- Panel radiators puted numerically under different environmental conditions.
