← ScienceWhich consequence results when refrigerant loses isenthalpic properties?
A)Reduced refrigeration performance and high temperature✓
B)Increased isentropic compressor efficiency
C)Minimal thermal work increase over cycle
D)High efficiency but low volume expansion
💡 Explanation
A phase-change refrigerant uses latent heat to cool systems. Loss of constant enthalpy reduces heat absorption because the isenthalpic expansion valve function degrades; therefore higher temperature from inefficiencies occurs rather than an efficient heat transfer.
