Résumé

In this study a heat transfer numerical simulation is described by a four compartment isothermal tank for the transport of perishable liquid foodstuffs tested inside an ATP chamber. The simulated tests were conducted according to the regulations specified in the United Nations ATP Agreement. A transient finite difference model is developed for a typical four compartment isothermal tank tested inside an ATP Testing Chamber with dimensions and specifications like that of the ATP chamber of the Zografou Campus of the National Technical University in Athens. For the control of the cooling/heating system a proportional integral controller is employed. The study describes a method for measuring the k-coefficient of a four compartment isothermal tank according to ATP specifications using ordinary laboratory equipments. With the suggested method, the testing of a four compartment tank is possible using only one PeI controller and one thyristor instead of the normally needed four independent PeI controllers and four thyristors in order to adjust the heat power needed inside each compartment of the four compartment isothermal tank.
