ABSORPTION-DIFFUSION REFRIGERATION METHOD AND APPARATUS Russian patent published in 1996 - IPC

FIELD: refrigerating equipment. SUBSTANCE: method involves additional supercooling of solution suppled into absorber by heat dissipation into zone with temperatures below ambient temperature, with heat being dissipated from solution interacting with vapor-gas mixture as well as from solution supplied into absorber. Heat dissipation is carried out by evaporating additional heat-carrier followed by condensation and returning of condensate into evaporation zone. Heat- dissipating members are in thermal communication with weak solution channel and absorber. Thermal communication between heat-absorbing member and heat-dissipating members is enabled through auxiliary heat-transfer member, which provides evaporating-condensing cycle, via heat tube or two-phase thermal siphon, or auxiliary heat-transfer device operating in the mode of single-phase thermal siphon, or through auxiliary heat-conductive plate. Auxiliary heat- transfer members in zones between heat-dissipating and heat-absorbing members are covered by heat insulating material. EFFECT: increased efficiency and enhanced reliability in operation. 18 cl, 1 dwg
