Apparatus and method for recovering volatile refrigerants

Abstract

A self-contained refrigerant recovery device for recovering refrigerant from a transfer vessel into a storage reservoir, comprising, in a single enclosure a qualitative analyzer for determining a quality of a refrigerant in the transfer vessel; a quantitative analyzer for determining a quantity of refrigerant in the transfer vessel; a refrigerant extractor for withdrawing refrigerant from the transfer vessel into a storage reservoir; an accounting system for determining a value of refrigerant in the transfer vessel based on the qualitative analysis and the quantitative analysis; and an output for outputting said value. The system preferably has a plurality of storage reservoirs, the refrigerant being withdrawn from the transfer vessel into one of said plurality of storage reservoirs based on said qualitative analysis. In operation, a single connection between the transfer vessel and the recovery device is sufficient.
