TWO-CHAMBER ABSORPTION REFRIGERATOR Russian patent published in 1995 - IPC

FIELD: refrigeration engineering. SUBSTANCE: low-temperature section 6 of the refrigerator is made up as a tank with vertical cylindrical walls and has door 5 in the cover of the cabinet. The low-temperature evaporator is made up as spiral 12 and connected with high-temperature evaporator 13 constructed as a split ring and having a heat contact with top metallic cover 10 of cooling chamber 2 through an insulating layer which separates the low-temperature section and cooling chamber. The low- temperature and high-temperature evaporators 12 and 13 are constructed as three-flow heat exchanger and compressed in the zones of heat contact in vertical and horizontal planes respectively. High-temperature evaporator 13 is in heat contact with the inner side of top cover 10 of the cooling chamber provided with fins 14 at sites where heat contact is absent. High-temperature evaporator 13 is in a heat contact with outer side of top side 10 of cooling chamber 2. The inner side of cover 10 is provided with fins 14 or it is in a heat contact with condensation parts of heat pipes or two-phase thermosiphons, the evaporation parts of the thermosiphons being in a heat contact with panels made of a metal having high heat conductivity and secured to the walls of cooling chamber. EFFECT: enhanced efficiency. 6 cl, 7 dwg
