Document Type and Number:
WIPO Patent Application WO/2019/009117
Kind Code:
A1
Abstract:
Provided is a refrigerant recovery apparatus comprising a compressor (31) which intakes refrigerant from a device (20) containing refrigerant to be recovered and a condenser (32) which sends the refrigerant discharged from the compressor (31) to a refrigerant recovery container (100) via a main refrigerant recovery path (70), wherein: a residual refrigerant recovery path (77) is provided in which the pressure of residual refrigerant from the condenser (32) is decreased within a branch path (76) which branches off from the main refrigerant recovery path (70), the compressor (31) intakes the residual refrigerant and pressurizes the same, and the residual refrigerant is sent to the refrigerant recovery container (100); and a cooling coil is connected on the outlet side of the condenser (32) upstream of the point where the main refrigerant recovery path (70) and the branch path (76) diverge.
