Abstract
A long-period storage accumulator for storing heat water is used as a storing medium. The water is enclosed in large thinwalled containers which are arranged under the ground. The water pressure forces acting on the container walls are carried by the surrounding of the container.
Claims5
A long-period heat storage accumulator adapted to contain a large volume of water where the accumulator is for use with a power station and where the accumulator has means for filling and removing water therefrom, the improvement comprising in that said accumulator is contained with a cavern formed from a rock formation whereby the pressure of the water in the accumulator is contained by the rock formation and in that an accumulator wall is spaced from the rock formation with the space between the rock formation and the wall being filled with compressed gas at a pressure equal approximately to the pressure of adjacent hot water.
A long-period heat storage accumulator adapted to contain a large volume of water where the accumulator is for use with a power station and where the accumulator has means for filling and removing water therefrom, the improvement comprising in that said accumulator is contained within a cavern formed from a rock formation whereby the pressure of the water in the accumulator is contained by the rock formation and in that a wall of the accumulator comprises a plurality of U-shaped rings with gaps between adjacent rings to absorb longitudinal expansion.
