Which consequence results when the refrigerant undergoes rapid throttling in a vapor-compression refrigeration cycle?

💡 Explanation

Icing results because rapid throttling causes a pressure drop and subsequent temperature decrease via the Joule-Thomson effect. This causes water vapor to condense and freeze, therefore lowering efficiency, rather than improving heat transfer or system superheat/subcool that would occur under different conditions.
