Patent ID: 11131489

Abstract:
A refrigerant recovery apparatus is connected between a target apparatus from which a refrigerant is recovered and a refrigerant recovery container. The apparatus includes a compressor, a condenser, and a residual refrigerant recovery path. The compressor sucks the refrigerant from a refrigerant circuit of the target apparatus and compresses the refrigerant. The condenser condenses the refrigerant discharged from the compressor and sends the refrigerant to the refrigerant recovery container through a main refrigerant recovery path. The residual refrigerant recovery path through which a decompression mechanism on a branch path branching from the main refrigerant recovery path decompresses a residual refrigerant in the condenser. The decompressed refrigerant is sucked into the compressor and pressurized. The pressurized refrigerant is sent into the refrigerant recovery container. An auxiliary heat exchanger is connectable near an outlet of the condenser and upstream of a junction between the main and branch paths.
