PROBLEM TO BE SOLVED: To provide a bleeder for a compression-type refrigerating machine capable of dispensing with taking in and out of lubricant, saving power for an oil pump, and discharging a noncondensing gas in a bleeding tank to the outside of a system while reducing the wear amount of a refrigerant. SOLUTION: In this compression-type refrigerating machine 1-1, a compressor 13, a condenser 17 and an evaporator 11 are connected by refrigerant piping 21, the bleeding tank 31 is connected with the condenser 17 by piping 33, and the noncondensing gas is collected in the bleeding tank 31. An absorption tank 35 filled with an absorbent 69 is connected with the bleeding tank 31 by piping 37, the noncondensing gas accumulated in the bleeding tank 31 is introduced to the absorption tank 35 to allow the refrigerant to be absorbed by the absorbent 69, and further the refrigerant vapor generated by being heated by an absorbent heater 71 is returned to a refrigerant circulating system of the evaporator 11 and the condenser 17 through piping 75 in regenerating the absorbent 69.
