FIELD: refrigeration engineering, particularly to freeze ground used for ice-ground barrier creation.
SUBSTANCE: cold accumulation device comprises casing pipe filled with coolant and including ground-submersed evaporator and condenser. Device also has condensing unit arranged over condenser and connected with line by pressure and discharge pipelines. The line is located in space defined between evaporator and shell and formed as pipe having elliptical cross-section densely wound on condenser. The space between the line and the shell is filled with heat insulation means. Cold accumulation device additionally has inlet pipeline with pressure compressor inlet and outlet pipeline. Inlet pipeline extends for the full length of casing pipe from the pressure inlet to evaporator through condensation zone. Outlet pipeline passes from pressure pipeline to casing pipe condenser.
EFFECT: increased economical efficiency, reduced casing pipe defrosting time and extended operational capabilities.
