← ScienceWhich outcome occurs when the adiabatic expansion within a refrigeration cycle drops below frost point?
A)Condensation forming ice crystal blockage✓
B)Superheating and compressor overheating
C)Increased system refrigerant flow rate
D)Vapor compression to subcooled liquid
💡 Explanation
Ice blockage results because exceeding saturation causes water vapour to undergo deposition directly to ice; rather than liquid condensation, the rapid cooling initiates crystal formation. Therefore blockage is probable, rather than a change in refrigerant flow or superheating.
