← ScienceWhich outcome occurs when isentropic compression exceeds optimal ratios in a refrigeration cycle using R-134a?
A)Increased superheat entering compressor✓
B)Decreased evaporator coil temperature
C)Higher refrigerant mass flow rate
D)Reduced compressor discharge temperature
💡 Explanation
Increased superheat occurs because excessively high compression ratios lead to increased work input by the compressor, which translates into higher refrigerant temperatures entering, therefore resulting in less cooling rather than enhanced cooling from alternatives with different states and compression ratios.
