← ScienceWhich consequence results when a refrigeration system's expansion valve malfunctions in regulating liquid refrigerant flow?
A)Increased superheat at evaporator exit
B)Decreased cooling capacity due to starving
C)Elevated condenser pressure from flooding✓
D)Stable, but reduced, Coefficient of Performance
💡 Explanation
Excessive refrigerant entering the evaporator leads to liquid flood-back; the mechanism is unrestricted phase transition. This increases condenser pressure greatly because unvaporized refrigerant bypasses the intended cooling process, therefore raising head pressure rather than improving operational efficiency.
