← TechnologyWhich outcome occurs when rapid compressor cycling arises in a refrigeration unit?
A)Decreased heat transfer efficiency✓
B)Increased refrigerant subcooling
C)Elevated evaporator superheat
D)Stable system thermal equilibrium
💡 Explanation
Decreased heat transfer efficiency happens when rapid compressor cycling leads to shortened run times; the evaporator coil undergoes repeated thermal stress due to frequent transitions. This reduces the average temperature difference to promote effective heat exchange, therefore diminishing heat absorption, rather than optimal levels.
