Open-Source vapor compression library (VCLib): Heat pump modeling for education and research

Vapor compression cycles have gained high importance due to increasing concerns regarding the decarbonization of heating and cooling applications. Typically, vapor compression cycles operate under dynamic conditions, making it difficult to predict their performance accurately. Dynamic simulation models present a decent solution for increasing the reliability of the performance assessment. However, the implementation of dynamic simulation models is a complex task, requiring a uniform description and model development. Therefore, this article introduces an open-source Vapor Compression Library called VVCLib based on a critical literature review of existing libraries for modeling and simulation of vapor compression cycles. The VCLib combines simulation models from the refrigerant through the component to the system level. The simulation models in the VCLib strictly follow a modular and scalable modeling approach. Class diagrams vividly describe the structure of models, making the VCLib easy to use for new users, especially students. The VCLib is open-source and accessible to support educational and research purposes:
