Under conditions for which the same room temperature is maintained by a heating or cooling system, it is not uncommon for a person to feel chilled in the winter but comfortable in the summer. consider a room whose air temperature is maintained at 24ºc throughout the year, while the walls of the room are nominally at 30°c and 10°c in the summer and winter, respectively. the exposed surface of a person in the room may be assumed to be at a temperature of 32°c throughout the year and to have an emissivity of 0.90. the coefficient associated with heat transfer by natural convection between the person and the room air is approximately 2 w/m2·k. calculate the following. heat flux due to convection: w/m2 heat flux due to radiation in the summer:   w/m2 heat flux due to radiation in the winter:   w/m2
