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.

Claims12

Dependent claims

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 first collection pipe through which the absorbent discharged from the first regenerator flows, and is connected to the absorber;
and
a second collection pipe through which the absorbent discharged from the second regenerator flows,
wherein the absorbent discharged from the first regenerator has a higher pressure than the absorbent discharged from the second regenerator,
wherein a confluence point where the absorbent flowing through the second collection pipe converges with the absorbent flowing through the first collection pipe is formed,
further comprising a bypass collection pipe branched between the second regenerator and the confluence point and connected to the absorber.
