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 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 refrigerant containers deliver one or more refrigerant components into the container to convert the recovered refrigerant.

Abstract: Methods, systems and apparatuses are described that are directed to on-site recovery and/or repurposing of refrigerant, where an original refrigerant is converted into a refrigerant different from the original refrigerant. The refrigerant different from the original refrigerant can have relatively lower global warming potential (GWP) than the original refrigerant. The recovery and/or repurposing can be implemented for example in a refrigeration circuit, such as for example in general cooling and/or heating applications, which may be embodied in a heating, venting, and air conditioning (HVAC) system and/or unit, in a transport refrigeration system and/or unit, as well as in commercial, residential and/or industrial cooling and/or heating applications.

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.
