Title:
ENERGY ACCUMULATOR, HEAT EXCHANGER SYSTEM FOR AN ENERGY ACCUMULATOR, ENERGY STORAGE SYSTEM AND CORRESPONDING METHOD
Document Type and Number:
WIPO Patent Application WO2006045551
Kind Code:
A3
Abstract:
The invention relates to an energy accumulator (10) which comprises an internal first accumulator (11) including a first storage medium (12) and a first heat exchanger system (30), and an external second accumulator (21) surrounding the first accumulator (11) and including a second storage medium (22), the first accumulator (11) exchanging heat with the second accumulator (21). The aim of the invention is to provide an advantageous seasonal energy storage. For this purpose, the first and second accumulator (11, 21) are configured as cold accumulators during a first period, whereby heat can be withdrawn from the first and/or second storage medium (12, 22), and are configured as heat accumulators during a second period, whereby cold can be withdrawn from the first and/or second storage medium (12, 22). The invention also relates to a heat exchanger system for an energy accumulator and to a method for operating said energy accumulator. The invention finally relates to an energy storage system and to a method for operating said energy storage system which is adapted to provide both cold and heat.
