Recovering refrigerant from a system in vapor phase minimizes the loss of what?

Recovering refrigerant from a system in vapor phase minimizes the loss of oil. This is because when refrigerant is recovered in the vapor phase, the oil, which tends to be heavier and may settle at the bottom of the compressor or other components, remains in the system rather than being drawn out along with liquid refrigerant. Liquid refrigerant can carry oil with it during recovery, resulting in a greater loss of oil from the system. By recovering only the vapor, the oil is less likely to be displaced or removed, thus helping maintain the proper amount of oil necessary for lubrication and optimal operation of the system.

In this context, losing water is not relevant to the recovery of refrigerant, as vapor recovery focuses specifically on the refrigerant and its associated oil in the system. While refrigerant loss through vapor recovery inherently occurs, the emphasis on minimizing oil loss highlights the importance of ensuring the system remains properly lubricated and functional.
