In this paper, a study of the well-posedness of the set of equations which form the model of a refrigeration system is presented.The conditions that the existence of some key components, such as the thermostatic expansion valve, orifice expansion device and the liquid receiver, are taken into account and fully discussed.For the purpose of the study, simplified models are considered for every component, relating the flow parameters and refrigerant properties.In any case a special care has been taken in order to assure a realistic physical behavior.First, the chosen models are presented, and then a full discussion about the closure of the equations depending on the chosen elements is given.Finally, a sample of a parametric study performed with the described method is presented.
