← ScienceWhich outcome results during reverse Brayton cycle operation?
A)Air exiting cools significantly further✓
B)Turbine power output greatly increases
C)Compressor efficiency approaches theoretical limit
D)System pressure variation becomes negligible
💡 Explanation
Refrigeration occurs due to adiabatic expansion. Isentropic expansion reduces temperature, because the Joule-Thomson effect converts internal kinetic energy into potential energy. Therefore, outlet temperature diminishes sharply rather than increasing, because the reversed cycle absorbs heat.
