← ScienceWhich outcome limits vapor compression chiller efficiency during liquid flashing?
A)Increased fluid superheat temperature
B)Reduced isenthalpic expansion efficiency✓
C)Higher compressor energy consumption
D)Decreased evaporator surface temperature
💡 Explanation
Reduced isenthalpic expansion efficiency results from vapor formation because throttling's pressure drop causes a portion to vaporize before the evaporator. This reduces the cooling capacity, therefore efficiency drops, rather than issues solely relating to compressor work or superheat.
