Recovering refrigerant from a system in the vapor phase primarily minimizes the loss of which component?

Recovering refrigerant from a system in the vapor phase primarily minimizes the loss of oil. In refrigeration systems, oil circulates with the refrigerant to lubricate the compressor and other moving parts. When refrigerant is recovered in the vapor phase, it allows for a more efficient removal of refrigerant while reducing the risk of oil being removed along with it.

If refrigerant is recovered in the liquid phase, there is a higher chance that oil, which is typically mixed with the refrigerant, will also be evacuated from the system. This loss can lead to insufficient lubrication and potential damage to the compressor over time. Therefore, utilizing the vapor recovery method helps maintain the integrity of the lubricant within the system, ensuring that it operates effectively and reducing the likelihood of future mechanical issues.

The other components presented in the choices, while important, do not directly relate to the specific advantage of minimizing oil loss in the vapor recovery process.
