1. A cooling machine comprising:
an absorber to generate an absorption solution by mixing a refrigerant and an absorbent;
a first regenerator to separate the absorption solution discharged from the absorber into the refrigerant and the absorbent;
a second regenerator to separate the absorption solution discharged from the absorber into the refrigerant and the absorbent;
a condenser to heat-exchange the refrigerant discharged from the first regenerator and the second regenerator;
an expansion device to expand the refrigerant discharged from the condenser; an evaporator to heat-exchange the refrigerant discharged from the expansion device and to discharge the refrigerant to the absorber;
a first drain pipe through which the refrigerant discharged from the first regenerator flows;
a second drain pipe through which the refrigerant discharged from the second regenerator flows; and
a gas-liquid separator to separate the refrigerant introduced through the first drain pipe and the second drain pipe into a gas state and a liquid state.
