FIELD: refrigerating and cryogenic engineering. ^ SUBSTANCE: invention relates to absorption-diffusion household and industrial refrigerators. Proposed refrigerator contains evaporator, condenser, fractional column, absorber, receiver, liquid heat exchanger, gas heat exchanger, generator with electric heater on weak solution tube with its vapor space connected through fractional column with condenser. Strong solution tube is installed in vapor space with its own sealed vapor space and with hydraulic back-pressure valve in lower part into which lower end of thermal siphon is dipped. Middle part of thermal siphon passes in strong solution tube, and its upper end gets from said tube into vapor space of weak solution tube. Capillary porous insert is made in middle part of weak solution tube vapor space over its passage section. ^ EFFECT: increased efficiency of refrigerator. ^ 4 cl 2 dwg |
