The temperature of the outside room is 30°C, and the combined convection and radiation heat transfer coefficient at the surface of the outer wall is 10 W/m2°C. It is proposed to insulate this section of the furnace wall with glass wool insulation (k = 0.038 W/m°C) in order to reduce the heat transfer by 90%. Assuming the outer surface temperature of the cold room wall section still remains at about 7°C, determine the thickness of the insulation that needs to be used. The company is questioning whether to insulate the section of piping between the evaporator and the compressor.
