Final answer:
Recovering refrigerant from a system as a vapor helps minimize the loss of oil, water, and refrigerant.
Step-by-step explanation:
When recovering refrigerant from a system as a vapor, the loss of oil, water, and refrigerant is minimized. By recovering the refrigerant as a vapor and not as a liquid, the oil and water that may be present in the system are not lost along with the refrigerant. This method helps to conserve resources and minimize wastage.
