DEAERATION MEMBRANE EXPANSION TANK Russian patent published in 2012 - IPC F24D3/02 

FIELD: heating.

SUBSTANCE: invention refers to independent heating systems, and namely to deaeration membrane expansion tanks, and can be used in independent heating and hot water supply systems for heating of internal volumes of buildings. Deaeration membrane expansion tank consists of the housing inside which there installed is membrane that is fixed in it by means of a flange; at that, internal volume of membrane is equal to volume of deaeration membrane expansion tank, and in lower part of the housing there installed are heat carrier connection pipes of the heating system and connection pipe of overflow tube; at that, membrane and housing in its upper part are equipped with non-return valve. Air volume of the housing of deaeration membrane expansion tank is connected to atmosphere through non-return valve and heat insulated by means of heat insulation.

EFFECT: effect consists in heat carrier pressure reduction, possibility of removing the gases dissolved in heat carrier through expansion tank, exclusion of air penetration from the tank air volume through membrane to heat carrier, and the increase up to 0,8-0,9 of the tank filling coefficient.
