Abstract

A method for servicing a refrigeration system is disclosed. The refrigeration system contains a refrigerant and has a compressor, a high-side section and a low-side section. The method includes the steps of releasing the refrigerant from the refrigeration system from the high-side section; collecting the released refrigerant with a recovery container containing a refrigerant adsorptive substance; charging the refrigeration system with inert gas from the low-side section; and discharging the inert gas from the refrigeration system from the high-side section.
