METHOD TO OBTAIN COLD IN ABSORPTION-DIFFUSION REFRIGERATING PLANT Russian patent published in 2007 - IPC F25B15/10 

FIELD: domestic refrigerating equipment.

SUBSTANCE: method involves supplying strong solution contained in vessels in separator from absorber by means of vapor-lifting pump operated by evaporated coolant passing from generator; delivering the solution from separator into additional separator with the use of additional vapor-lifting pump operated by evaporated coolant passing from separator; supplying the solution from absorber to further additional separator with the use of additional vapor-lifting pump operated by means of evaporated coolant passing from additional separator, wherein additional valor-lifting pump and further additional vapor-lifting pump are serially included in evaporated coolant line arranged between separator and condenser; delivering evaporated coolant from further additional separator to condenser; supplying the solution from additional separator and from further additional separator into absorber, wherein liquid cavities of additional separator and further additional separator are serially linked in solution line between weak solution supply jet, which delivers weak solution from generator into absorber, and strong solution outlet jet, which discharges strong solution from vessel into vapor-lifting pump.

EFFECT: increased completeness of ammonia vapor absorption from vapor-and-gas mixture and, as a result increased efficiency of absorber operation.
