The roof of a parked refrigerated truck compartment is of composite construction, consisting of a layer of foamed urethane insulation 12 = 65 mm, k = 0.026 W/m K) sandwiched between aluminum alloy panels ( = 5 mm, k» 180 W/m.K). The length and width of the roof are L = 12 m and W = 3.5 m, respectively, and the temperature of the inner surface is 7.) = -10°C. Consider conditions for which the truck is not moving the air temperature is T. = 30°C, and the solar irradiation is G, = 900 W/m2. Frank & Dave's w The T. DT For as = = = 0.6, determine the outer surface temperature7...in C, and the heat load, in W. imposed on the refrigeration system. Evaluate air properties at 310 K. Hint: Assume 7 > 7 and Ray > 10%
