Abstract
A long-period storage accumulator for storing heat water is used as a storing medium. The water is enclosed in large thin-walled containers which are arranged under the ground. The water pressure forces acting on the container walls are carried by the surrounding of the container.
Claims7
A combination of a long period heat storage accumulator adapted to contain a large volume of water and a power station, said accumulator having means for filling and removing water therefrom and said power station having a turbine, a refrigeration compressor having a liquified refrigerant and a clutch for operatively connecting said turbine and said compressor;
- the improvement comprising in that said accumulator is contained within a cavern formed in a salt rock formation whereby the pressure of the water in the accumulator is contained by the rock formation, in that the water comprises a saturated salt solution obtained by dissolution of the salt rock formation, in that the accumulator has a heat exchanger therein acting as a condenser for the turbine, in that means are provided for feeding a liquified refrigerant into the accumulator whereby a brine mixture is formed, and in that a means is provided for bringing a brine ice mixture into contact with the heat exchanger.
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 in a salt rock formation whereby the pressure of the water in the accumulator is contained by the rock formation, and in that the water comprises a saturated salt solution obtained by dissolution of the salt rock formation.
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 thereform;
- 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, in that the accumulator has a hollow cylinder arranged in its upper region, in that the accumulator has perforated channels situated beneath the hollow cylinder through which a refrigerant condensate may enter, and in that the underside of the cylinder communicates with the bottom region of the accumulator by means of a tube.
