Cooling of Aluminium Coils by Forced Ventilation with Outdoor Air

The subject of this doctoral thesis is the cooling of aluminium coils by forced ventilation with outdoor air. This method enables the coils to be cooled directly in the storage area of the intermediate storage after hot rolling, thus avoiding the need for relocation and the use of refrigeration machines. Free cooling with outdoor air, using mechanical ventilation, is widespread in the supply of air conditioning, but is rarely used in manufacturing, where the temperature level requirements are usually outside the available bandwidth. By using free cooling, the energy input, and thus the CO2 emission for the cooling process is greatly reduced. The aim of this thesis is to adapt the process of free cooling to the cooling of aluminium coils, and thereby to better understand the thermal properties of the coils. A suitable air flow solution in an open warehouse that fits to the general conditions of the production process is proposed. For this purpose, a thermal model of the coils is created and the cooling behaviour as well as the required airflow is determined. The model and the calculations are verified in the pro-cess. The thesis provides a robust calculation model to determine the behaviour of the coils and a suitable method of airflow design.
