Abstract

A method of converting a refrigerant includes recovering a refrigerant from a refrigeration unit with an evacuation pump and containing the recovered refrigerant in a container. The method also includes testing the recovered refrigerant and converting the recovered refrigerant. The converted refrigerant is different from the recovered refrigerant. A system for converting a refrigerant includes an evacuation pump, a container, and one or more refrigerant containers. The evacuation pump and container are configured to recover a refrigerant from a refrigeration unit. The one or more containers deliver one or more refrigerant components into the container to convert the recovered refrigerant.
