A numerical model for the design of a climatic chamber

In the present paper, we develop a numerical analysis supporting the design of a climatic chamber suitable for tracked and wheeled tractors, i.e. having measures 5x8x4 m3 (length x width x height).. The numerical analysis is performed by employing Matlab-Simulink, to simulate the behavior of transient systems. First, the balance equations are written with reference to the 5 blocks that can describe the climatic chamber. Then two different regimes are investigated. First, a period of 10 hours is considered in order to reach the prescribed conditions for the climatic chamber. Then, after this preparation period, the tractor’s engine is supposed to work. The performed analysis has shown that higher values of the adduction coefficient are preferable. Moreover, the dynamical analysis turned out to be a very useful instrument to drive the design.
