Introduction
The Compression Refrigeration Performance Determination Educational Unit Operations Pilot Plant is an integrated laboratory system designed for higher education institutions to demonstrate the thermodynamic principles of vapor-compression refrigeration. It provides undergraduate students in engineering disciplines with a practical platform to analyze refrigerating cycles, evaluate energy efficiency, and understand thermodynamic processes. To meet diverse teaching and curriculum requirements, the pilot plant supports comprehensive customization across both hardware and software configurations, allowing universities to align the equipment with their specific laboratory objectives.
Key Educational Features and Advantages
- Dual Performance Coefficient Evaluation: Enables independent determination of both the compressor-specific coefficient of performance (COP) and the overall system COP, helping students distinguish between component-level efficiency and total system efficiency.
- Regenerative Cycle Comparison: Supports comparative experiments with and without heat recovery. Students can actively analyze the thermodynamic impact of regeneration on system efficiency, subcooling, and energy savings.
- Calorimeter Calibration Practice: Allows students to measure and calibrate the heat leakage coefficient of the evaporator calorimeter, introducing them to real-world engineering calibration methods and heat loss calculations.
- Thermodynamic Mapping: Facilitates the recording of system pressures and temperatures to plot cycles on pressure-enthalpy (p-h) diagrams, assisting in the visual study of normal, saturated, and supersaturated operating states.
- Safe and Environmentally Conscious Design: Utilizes non-toxic, environmentally stable secondary refrigerants to ensure a safe laboratory environment for students and instructors.
- Synchronous Monitoring: Features a centralized instrumentation panel with analog pressure gauges, digital temperature displays, and electrical meters, providing real-time data visualization during laboratory demonstrations.
