Experiment: Vapor Compression Refrigeration

Click For Summary
SUMMARY

The discussion centers on the calculation of the Coefficient of Performance (COP) for vapor compression refrigeration systems. The user reports that the ideal COP calculated is lower than the COP derived from the pressure-enthalpy (p-h) diagram. Participants emphasize the need for detailed calculations and results to provide accurate assistance, indicating that discrepancies in COP values can arise from various factors in the calculation process.

PREREQUISITES
  • Understanding of vapor compression refrigeration cycles
  • Familiarity with Coefficient of Performance (COP) calculations
  • Knowledge of pressure-enthalpy (p-h) diagrams
  • Basic thermodynamic principles
NEXT STEPS
  • Review the principles of vapor compression refrigeration cycles
  • Study the methods for calculating Coefficient of Performance (COP)
  • Learn how to interpret pressure-enthalpy (p-h) diagrams
  • Explore common sources of error in thermodynamic calculations
USEFUL FOR

Engineering students, HVAC professionals, and anyone involved in the design or analysis of refrigeration systems.

i have calculated the coefficient of performance COP for both COP ideal and COP from p-h diagram. But the COP ideal i get is lower than the COP i calculated from p-h diagram. is it possible? please help :)

We cannot help you without more information, you need to at least walk us through how you calculated the two values and what the results were.
