Simulation model structure numerically robust to changes in magnitude and combination of input and output variables.

Author(s) : RASMUSSEN B. D., JAKOBSEN A.

Summary

In the common used models the coupling structure of the component models represents the actual flow path of refrigerant in the system. Very often numerical instabilities prevent the practical use of such a system model for more than one input/output combination and more than one capacity. A higher numerical robustness of system models can be achieved by making a model for the refrigeration cycle, the core of the system model and by using variables with narrow definition intervals for the exchange of information between the cycle model and the component model.
