THERMAL ACCUMULATOR (OPTIONS) Russian patent published in 2023 - IPC F24H7/00 F24H9/02 F24H9/45 

FIELD: heating engineering.

SUBSTANCE: heat accumulator used for heating and hot water supply of residential and non-residential premises. In the first embodiment, the heat accumulator includes a housing consisting of a cylindrical shell with torispherical end surfaces, on which a drain pipe, a pipe for connecting to the heating system, and an outlet for connecting the anode are located. On the side surface of the housing at different heights there are pipes for connecting various types of valves, both shut-off and control. The body has thermal insulation in the form of a removable cylindrical casing, the outer surface of which contains a lining. At the bottom, the housing is connected to an annular support. Also on the body at different heights there are pipes for connecting measuring instruments. In the second embodiment, the heat accumulator has all features of the first embodiment, while the body of the heat accumulator in the internal space contains a hot water supply circuit in the form of a coil twisted in a spiral.

EFFECT: creation of a heat accumulator operating under high pressure of the coolant with low maintenance complexity, the implementation of rapid heating of water in the hot water supply circuit, the protection of the internal surfaces of the heat accumulator body from corrosion and scale, and the preservation of the working energy of the coolant.
