Abstract: Apparatus for recovery, storage, and recharging of refrigerant used in an outside air conditioning or refrigeration system which provides faster operation while ensuring complete recovery of refrigerant, using the minimum of components for maximum portability. This apparatus employs a compressor condenser assembly to utilize the stored refrigerant itself directed in an evaporating refrigerating cycle. The cooled stored refrigerant then contact condenses and cools the recovered refrigerant from the outside system. During recovery operation the open-cycle compressor condenser unit can also be used to recover refrigerant so as to increase the recovery rate and to allow a more complete recovery of refrigerant. In addition, the apparatus includes a recharging circuit which can discharge refrigerant to an outside system and a system to purify the stored refrigerant for reuse.
