Which action is performed after initial liquid removal during refrigerant recovery?

After the initial liquid removal during refrigerant recovery, the next action typically performed is vapor recovery. This step is crucial because, after the bulk of the refrigerant in liquid form has been removed, the remaining refrigerant in the system often exists in the vapor phase. To ensure the system is properly evacuated of all refrigerants, it's essential to recover any remaining vapor, which can also contain refrigerant contaminants.

Vapor recovery involves using a refrigerant recovery machine to extract the gaseous refrigerant from the system, allowing for effective recovery and minimizing any potential environmental impact. This is particularly important under the EPA regulations, as it prevents the release of harmful refrigerants into the atmosphere.

Other actions, such as evacuating the system, pressure testing, and adding fresh refrigerant, are not typically performed immediately after the initial liquid removal. For instance, evacuation generally follows the complete recovery of both liquids and vapor to remove any moisture or air before recharging the system.

Thus, vapor recovery stands out as the correct choice following liquid removal as it aligns with best practices for handling refrigerants safely and efficiently.
