Final answer:
Recovering refrigerant in vapor phase will minimize the loss of oil, ensuring the system's oil balance is maintained for optimal operation.
Step-by-step explanation:
Recovering refrigerant from a system in vapor phase will minimize the loss of oil. When refrigerant is recovered as vapor, it leaves most of the system's oil behind. The goal is to maintain the correct oil balance within the system, as too much oil removal can harm the compressor and affect the system's efficiency.
The vapor recovery method helps to ensure that the majority of the oil stays within the system's compressor, where it is needed for lubrication and operation. This is in contrast to liquid-phase recovery, which can carry out a significant amount of oil along with the recovered refrigerant, potentially leading to a shortage of oil in the system.
