You can save time recovering the refrigerant from a system by removing as much as possible in the ___________________ phase?

Recovering refrigerant from a system can be optimized by focusing on the liquid phase because refrigerants are more concentrated in this state. During the liquid phase, the refrigerant is in a denser form, which allows for a more efficient and quicker recovery process compared to when the refrigerant is in the vapor phase.

In the liquid state, the refrigerant is easier to extract through the recovery unit due to its higher density and lower specific volume, enabling a faster transfer of coolant. This method minimizes the amount of time spent on recovery, making the process more effective.

When refrigerant is in the vapor phase, it is less compact and more spread out, which can result in a slower and less efficient recovery, as more time is needed to move the gas and achieve complete recovery. Therefore, focusing on the liquid phase during refrigerant recovery provides the most effective means of saving time and enhancing the overall recovery process.
