In this work, detailed experimental studies were carried out aimed at testing the operating modes of the refrigeration unit "Refrigerator-2" model STX 02.00.01. The purpose of the study was not only to demonstrate the functioning of a two-chamber compression refrigerator, but also to solve a number of educational problems. These tasks included examining process operations, simulating various faults, and recording and analyzing refrigerant data to gain a deeper understanding of how the system performs under different conditions. The study focused on simulating various faults and assessing their impact on the plant. As part of the analysis, a pressure-enthalpy (i-P) diagram was constructed using the specialized CoolPack program. This data has also been visualized in Microsoft Excel for more visual representation and easy analysis. The results of the study demonstrated that the unit operates stably in nominal mode, periodically switching to a stationary state and reactivating at certain intervals. Such a mode of operation indicates the reliability and consistency of the functioning of the refrigeration unit, which is confirmed by both the obtained diagrams and data analysis. These results highlight the effectiveness of the proposed diagnostic and troubleshooting methods, and provide a basis for further research and optimization of equipment performance.
