CELLAR WITH COLD ACCUMULATOR Russian patent published in 2013 - IPC F25D3/02 E02D29/00 E21D13/00 

FIELD: personal use articles.

SUBSTANCE: cellar is designed in the form of an underground structure having the products accommodation chamber and containing a vessel with a cold accumulation liquid, a means for the said liquid cooling having a sealed body loaded with a heat medium containing serially connected parts representing the evaporation zone, the transportation zone and the condensation zone in the form of a vertical finned tube, choked from above and positioned over the ground surface. The floor of the products accommodation chamber (within part of its area) has an indentation wherein the said vessel with cold accumulation liquid is positioned. The vessel is made of an elastic material and has an excessive volume so that to provide for expansion of the said liquid during liquid-to-solid phase transition; the vessel is confined in a rigid protected casing (open from above) so that to enable close fitting to its inner surface. Part of the body of the means for cooling the cold accumulation liquid, representing the transportation zone, is designed in the form of a tube passing vertically through the products accommodation chamber and the ground layer positioned over it prior to connection to the part representing the condensation zone. The means for cooling the cold accumulation liquid additionally contains a manifold installed between the evaporation zone and the transportation zone and representing a tube choked at the both ends, bent in the form of an open ring and having connection to the transportation zone within its middle part. The choked ends of the said tube are positioned at the same height as the part connected to the transportation zone or below such part to impart a slope equal to several degrees to the manifold. The evaporation zone is formed by the total of several vertical rectilinear nipples having choked bottom ends and connected to the manifold from the bottom via their top ends with the connection spots uniformly distributed across the manifold length. The manifold and the said nipples are sized and positioned so that to enclose the said rigid protective casing with the vessel with cold accumulation liquid confined therein. From among the said parts of the means for cooling the cold accumulation liquid at least the said manifold and the vertical nipples are made of an easily deformable metal.

EFFECT: cellar simplified design, increased efficiency of cold accumulation, enhanced reliability and reparability of the cellar.
