Consider a person standing in a room maintained at 20°C at all times. The inner surfaces of the walls, floors, and the ceiling of the house are observed to be at an average temperature of 15°C in winter and 30°C in summer. Determine the rate of radiation heat transfer between this person and the surrounding surfaces if the exposed surface area and the average outer surface temperature of the person are 1.2 m² and 34°C, respectively. Given: ε_skin= 0.95, σ = 5.67x10^(-8) W/(m^2∙K^4 ).

Consider a person standing in a room maintained at 20°C at all
times. The inner surfaces of the walls, floors, and the ceiling of the
house are observed to be at an average temperature of 15°C in
winter and 30°C in summer. Determine the rate of radiation heat
transfer between this person and the surrounding surfaces if the
exposed surface area and the average outer surface temperature
of the person are 1.2 m2 and 34°C, respectively. Given: Eskin =
0.95, o = 5.67x10^(-8) W/(m^2-K^4).
Heat Radiation in Winter (W) =
Heat Radiation in Summer (W) =
