Picture tube fabrication at LG.Philips Displays Germany GmbH
Picture tubes up to a diagonal size of 36" are fabricated at the plant in Aachen. Substantial heating load is produced in the halls by the pump line, adhesive, blackening and scaling furnaces. At the same time the production is so sensitive with regard to drafts and dust generation that it is not possible to react with correspondingly large ventilation equipment.
By using dynamic building and equipment simulation and the application of different measuring techniques the heat loading was portrayed in a mathematical model such that the expected success of different improvement measures could be determined in advance.
