A freezer is 1 m wide and deep, and 2 m high, and must operate at -10 degree C when the ambient air is at 30degree C. What thickness of polysterene is required if the load on the refrigeration unit should not exceed 200W? Assume that the outer surface of the insulation is approximately at the ambient air temperature and that the base of the freezer is perfectly insulated.
