    Abstract

    When designing a user interface for a simulation model there are several important issues to consider: Who is the target user group, and which a priori information can be expected. What questions do the users want answers to and what questions are answered using a specific model?When developing the user interface of EESCoolTools these issues led to a series of simulation tools each with a specific purpose and a carefully selected set of input and output variables. To allow a more wide range of questions to be answered by the same model, the user can change between different sets of input and output variables. This feature requires special attention when designing the user interface and a special approach for controlling the user selection of input and output variables are developed. To obtain a consistent system description the different input variables are grouped corresponding to the phenomena they describe and the user can select only one input variable per phenomena. This method ensures that all phenomena are described - i.e. the equation system is non singular.Numerical robustness of the model is assured by applying a so-called cycle-cored numerical structure, which has the consequence that the user does not have to specify any start guesses, etc.The design approach developed have resulted in a number of simulation tools which allow users with limited theoretical knowledge about refrigeration systems, mathematical models and simulation to use them while the expert users still have a lot of flexibility in choosing input variables and in assigning values of parameters.
