Which outcome occurs when rapidly depressurizing a liquid refrigerant below its saturation pressure?

💡 Explanation

When rapidly depressurizing, the liquid refrigerant undergoes flash evaporation because sudden pressure reduction causes immediate phase change, potentially leading to vapor-lock, disrupting system circulation. Therefore, vapor-lock disrupts circulation, rather than superheating, subcooling, or polymerization, which would require different mechanisms or conditions.
