Calculate the thickness of the corkboard insulation

Reference no: EM13262967

A walk-in freezer 4 m wide and 3 m high is to be built. The wall consists of 1.7 mm thick stainless steel (k = 14.2 W/mK), 10 cm thick foam insulation (k = 0.34 W/mK), a thickness of corkboard (k = 0.043 W/mK), and 1.27cm thick wood siding (k = 0.43 W/mK). The inside of the freezer is maintained at -40Â°C. Ambient air outside the freezer is at 32Â°C. The heat transfer coefficient is 5 W/m2K on the wood side of the wall and 2 W/m2K on the stainless steel side. If the outside air has a dew point of 29Â°C, calculate the thickness of the corkboard insulation that will prevent condensation of moisture on the outside wall of this freezer.
