The main aim of the chapter is to create a cost-effective refrigeration system capable of monitoring temperature and pressure variations, and calculating the coefficient of performance (COP) of the refrigeration system. This fully instrumented experimental test rig integrates compressor, condenser, evaporator, and expansion valve, alongside temperature sensors, and pressure transducers for comprehensive data collection for demonstration and experimentation of the refrigeration principles. The graphical user interface (GUI) is also developed using PyQt for data visualization and control of experimental parameters. This developed test setup is validated by various trial experiments. The experiments are performed under normal and sub-cooling conditions to assess the system's COP.

摘要

The main aim of the chapter is to create a cost-effective refrigeration system capable of monitoring temperature and pressure variations, and calculating the coefficient of performance (COP) of the refrigeration system. This fully instrumented experimental test rig integrates compressor, condenser, evaporator, and expansion valve, alongside temperature sensors, and pressure transducers for comprehensive data collection for demonstration and experimentation of the refrigeration principles. The graphical user interface (GUI) is also developed using PyQt for data visualization and control of experimental parameters. This developed test setup is validated by various trial experiments. The experiments are performed under normal and sub-cooling conditions to assess the system's COP.
