ABSORPTION REFRIGERATING MACHINE Russian patent published in 2021 - IPC F25B15/02 

FIELD: refrigeration engineering.

SUBSTANCE: invention relates to refrigeration engineering, in particular to ejector absorption refrigerating machines used in power generation, petrochemistry, oil refining and other fields of science and technology where low-potential sources of heat are available and there’s a need for refrigeration. An absorption refrigeratinf machine containing a closed circulation circuit, in which a generator, an ejector, an absorber, a condenser, a throttle, an evaporator, a pump, a heat exchanger are installed and a desorber without a dephlegmator is additionally introduced. The generator is designed in such a way that it is thermosophonic and of high circulation ratio. The ejector is installed between the desorber and the absorber.

EFFECT: increase in the thermal coefficient (refrigerating capacity ratio to heat supplied) of the refrigerating cycle.
