摘要： A refrigerant recovery unit that diverts blended refrigerant withdrawn out of a refrigerant system to an external tank outside the refrigerant recovery unit for reclamation includes a recovery circuit coupled on one end to the refrigerant system and coupled on another end to the external tank, a controller in communication with the recovery circuit for controlling a transfer of the refrigerant withdrawn from the refrigerant system to the external tank, and a valve operatively engaged with the controller and the recovery circuit and operable to transfer the refrigerant withdrawn from the refrigerant system to the external tank for recycling or reclamation.

摘要： A method for using refrigerant to check for a leak in a refrigerant system is provided that establishing fluid communication between a refrigerant recovery unit and a refrigerant system. The refrigerant recovery unit passes a refrigerant through the refrigerant recovery unit, compresses the refrigerant utilizing the refrigerant recovery unit, and transfers the compressed refrigerant from the refrigerant recovery unit directly into the refrigerant system. Additional refrigerant is added into the refrigerant system until a desired system pressure is reached, and then the refrigerant system is checked for leaks.
