A cheese ripening room which, has a total surface area of A = 25.0m2, has to ensure that
the inside temperature does not exceed 11.0°C at all times. If the maximum outside
temperature is 35.0°C and the cheese ripening room has an air conditioner which provides
125 kW of cooling, calculate the how thi ck the wooden walls would need to bein mm, in
order to ensure the inside temperature do es not go above 11.0°C. Assume that the thermal
