The article describes the structure and operation of virtual one-dimensional dynamic model of the solar heating system using components from the libraries of the EcosimPro program. The model is based on a fragment of a real hybrid sorption-compressor refrigeration system, designed and built in the Laboratory of Thermodynamics and Thermal Machines Measurements at the Faculty of Mechanical Engineering of the Cracow University of Technology. In the second part of the paper, the results of the dynamic simulation are shown along with their comparison to the actual measurement data recorded during one day (and night).
