Zusammenfassung:To inhibit deterioration of refrigerant recovery efficiency and work efficiency in a refrigerant recovery device including a compressor (31) for sucking a refrigerant from a refrigerant recovered device (20) and a condenser (32) for sending out the refrigerant discharged from the compressor (31) to a refrigerant recovery container (100) through a main refrigerant recovery path (70).SOLUTION: A refrigerant recovery device includes a residual refrigerant recovery path (77) for decompressing a residual refrigerant in a condenser (32) within a branch path (76) branched from a main refrigerant recovery path (70), sucking and compressing the refrigerant by using a compressor (31) and sending out the refrigerant to a refrigerant recovery container (100). A cooling coil is connected to an upstream side of a branch point between the main refrigerant recovery path (70) and the branch path (76) on an outlet side of the condenser (32).SELECTED DRAWING: Figure 1 【課題】冷媒被回収機(20)から冷媒を吸入する圧縮機(31)と、圧縮機(31)から吐出された冷媒を主冷媒回収経路(70)で冷媒回収容器(100)へ送り出す凝縮器(32)とを有する冷媒回収装置で、冷媒の回収効率や作業効率が低下するのを抑制する。【解決手段】主冷媒回収経路(70)から分岐した分岐経路(76)内で凝縮器(32)の残留冷媒を減圧し、圧縮機(31)で吸入加圧して冷媒回収容器(100)へ送り出す残留冷媒回収経路(77)を設け、凝縮器(32)の出口側における主冷媒回収経路(70)と分岐経路(76)の分岐点の上流側に冷却コイルを接続する。【選択図】図1
