Abstract: The present disclosure relates to an absorption cooling machine including an absorber, a first regenerator, a second regenerator, a condenser, an expansion device, and an evaporator, and relates to a cooling machine that connects a bypass collection pipe that guides an absorbent flowing back into the second regenerator to be collected into an absorber to a second collection pipe, in order to prevent the water level of the second regenerator from being raised as the absorbent cannot be collected by the absorber and flows back to the second regenerator, due to the pressure difference between an absorbent separated from the first regenerator and collected into the absorber through the first collection pipe, and an absorbent separated from the second regenerator and collected into the absorber through the second collection pipe.

Abstract: The present disclosure relates to an absorption cooling machine including an absorber, a first regenerator, a second regenerator, a condenser, an expansion device, and an evaporator, and relates to a cooling machine that prevents the refrigerant from flowing backward to the first regenerator under a low pressure condition by installing a gas-liquid separator that separates the refrigerant discharged from the first and second regenerators and flows into the condenser into a gas state and a liquid state, in order to heat the absorption solution supplied from the absorber to separate into a refrigerant and an absorbent, and to smoothly discharge the refrigerant from the first regenerator and the second regenerator for discharging the separated refrigerant to the condenser.

Abstract: An absorption refrigeration machine may include a first regenerator for primarily regenerating an absorbing liquid absorbing a refrigerant; a second regenerator for secondarily regenerating the absorbing liquid primarily regenerated from the first regenerator; an auxiliary absorber provided with the second regenerator, to allow an auxiliary absorbing liquid to absorb the refrigerant; and an auxiliary regenerator for regenerating the auxiliary absorbing liquid carrying the refrigerant in the auxiliary absorber.
