PURPOSE: An extraction system of an absorption refrigerator is provided to automatically emit non-condensed gas by mounting a vacuum pump to a blowoff pipe, to expand the life span of a sensor and to improve the reliability for sensing solution level by keeping the constant gap of a sensing unit of the sensor from the drive set-solution level of the vacuum pump. CONSTITUTION: An extraction system of an absorption refrigerator is composed of a separator(4) for connecting a non-condensed gas and refrigerant steam intake pipe(6) between the lower part of a separator body(5) and a condenser(1), linking a pipe connected to an eject unit of a solution pump(3) and an ejector(8) to the non-condensed gas and refrigerant steam intake pipe, and connecting the inner part of the separator body and an absorber(2) by a solution return pipe(10); an extracting tank(11) connected to the upper part of the separator body by a non-condensed gas eject pipe(12) and linked with a blowoff pipe(13); a vacuum pump(20) mounted to the blowoff pipe; and a sensor(21) for installing a sensor body(22) to the upper part of the extracting tank and positioning a sensing unit(23) to keep the constant gap from solution level in the non-condensed gas eject pipe by connecting the sensing unit to the sensor body with a cable(24).
