A refrigerator stands in a kitchen where the room temperature is 22 °C. The surface temperature on the outside of the refrigerator is 15 °C. The sides are 30 mm thick and have a thermal conductivity of 0.15 W/m K. The heat transfer coefficient on the outside is h = 10 W/m2K. Assuming one-dimensional heat conduction through the sides, calculate the net heat flow and surface temperature on the inside of the refrigerator.
