Abstract
In refrigeration systems, a set of devices is applied for the provision of cooling, for the transfer of reject heat to ambient and for circulation of the respective heat carrier fluids. Aiming at energy-efficient operation of the entire system, a complex optimization exercise is found, characterized by the number of degrees of freedom and the interdependence of the different components. In order to form a realistic model of the system, the operating characteristics of all system components must be modeled in sufficient quality. In order to allow for sufficient precision of the models, e.g. for representation of part load behavior, a nonlinear optimization has to be applied. Overall, a considerable effort for the development and application of a mathematical optimization of complex refrigeration systems is required. Within the framework of this study, a method is shown to make the application of optimization methods also available for smaller refrigeration systems.
