The physical modeling and transient simulation of a vapour compression refrigeration system are useful tools in heating, ventilating, air conditioning and refrigeration for optimization of physical models. Dymola behavior modeling from Dassault systèmes 3d experience is a multi-domain dynamic simulation tool useful for predicting the performance of the physical systems. The library is based on the free Modelica language which contains basic correlations for heat and mass transfer, pressure drop, control volumes, flow resistances and advanced ready-to-use models for all basic components of refrigeration systems like pipes, heat exchangers, compressors, expansion devices and accumulator with different refrigerants. Thermal library is a commercial library for the steady and dynamic simulation of refrigeration system with the latest multiport extruded tube heat exchangers over tube in tube and round tube plate fin heat exchangers with multiple options for compressor and expansion valve. The simulation with the help of Dymola behavior modeling performed by initializing various parameters for condenser, evaporator, compressor and COP is found to be 3.637.
