← ScienceWhat outcome occurs in a cryogenic refrigeration system when a gas leaks such that heat transfer increases during a phase shift?
A)Increased system operating temperature
B)Lowered refrigeration cycle efficiency✓
C)Accelerated refrigerant phase transitions
D)Elevated compressor discharge pressure
💡 Explanation
Lowered refrigeration cycle efficiency is the outcome because increased heat transfer due to leakage results in a less efficient phase transition; this introduces more disorder via the increased entropy generation, therefore efficiency plummets, rather than a rise in temperature because excess injected energy increases system entropy affecting heat differential.
