Correct Answer: Option B — When recovering refrigerant from the centrifugal chiller using this method, it minimizes the risk of chiller tube freeze-up.

Specific recovery methods utilizing vapor-trapping or auxiliary cooling techniques prevent rapid pressure drops that cause localized water chilling, thereby eliminating the risk of freezing and rupturing expensive chiller tubes during evacuation.
