LOW-TEMPERATURE CHAMBER Russian patent published in 2008 - IPC F25D11/00 F25D19/00 

FIELD: heating, refrigerating engineering.

SUBSTANCE: invention relates to refrigerating engineering, particularly, to domestic and commercial low-temperature chambers (SLTC) with absorption-diffusion refrigerating machines (ADRM). Low-temperature chamber comprises a thermal-insulated housing of bin-type with internal metal chamber and refrigerating unit, evaporator of which is located beyond the usable volume of the chamber and is thermally connected with the usable volume. Two ADRMs installed at the side walls of housing are used a refrigerating unit. The side walls have openings where thermal-insulated units are installed. Thermal-insulated units are made of a high heat-conductivity metal in the form of box. From one side the box bottom is thermally connected to ADRM evaporator, from the other side - to the internal metal chamber. Rear and front walls of the internal metal chamber are additionally thermally-connected to the side walls by means of heat transfer equipment. Heat-removal sections of this equipment are installed at the area of thermal connection to ADRM evaporators. Heat pipes and two-phase or single-phase thermal siphons are used as heat transfer equipment. ADRM components, located beyond the housing, are closed with jackets having air openings at the upper and lower parts. Air fans are installed at the channels formed by jackets and side walls of the housing.

EFFECT: enhancement of low-temperature chamber performance characteristics on repairability.
