Consider a person standing in a room maintained at 72F at all times. The inner surfaces of the room (walls, floors, and ceiling) are at an average of 14C in the winter and 30C in the summer. Determine the rate of radiation heat transfer between this person and the room inner surfaces, assuming the exposed surface area of the person is 1.8 m2, the average outer temperature of the person is 35C, and the emissivity of a person is 0.95. Using your results, explain why you might feel cold in the winter at the same temperature as the summer?
