It takes large thermal storage tanks to heat apartment buildings highly efficiently. To install them, they have to fit through standard door openings in existing buildings. The BINE Projektinfo 3/2017 “Large storage tank developed for small spaces” introduces a model that makes this easy. It consists of multiple modules and has lower heat losses than the cascade storage systems previously used.
The thermal storage tank is not fully assembled until it reaches the boiler room
The individual oval steel modules of the storage tank are mounted close to each other on rails during the installation and are then pushed together. They have a volume of 1350 litres each. The pipe connections between the individual modules are in the vessel.
“UniSto”, as the new storage tank is called, offers the same volume but a smaller and fully insulated surface, which reduces heat loss. It is insulated with hard shells of expanded polystyrene. Vacuum insulation panels (VIP) can be fitted in the cavities within the hard shells if required.
The storage tank has already been trialled in several field tests. For example, a Swiss-German energy supply company installed a prototype in a nursing home in Rheinfelden.
A heat-led, gas-fired combined heat and power plant and a gas condensing boiler for peak loads meet all heating requirements of the 74 residential units and partially cover the electricity demand.
The storage tank is hydraulically integrated in the system so that it stores the waste heat from the combined heat and power system and can make it available both for space heating and heating drinking water.
Research in the “UniSto” project was performed by an industrial consortium involving the Institute for Thermodynamics and Thermal Engineering (University of Stuttgart) and Consolar Solare Energiesysteme GmbH, among others.

About BINE Information Service
Energy research for practical applications
The BINE Information Service reports on energy research topics, such as new materials, systems and components, as well as innovative concepts and methods. The knowledge gained is incorporated into the implementation of new technologies in practice, because first-rate information provides a basis for pioneering decisions, whether in the planning of energy-optimised buildings, increasing the efficiency of industrial processes, or integrating renewable energy sources into existing systems.

The Fraunhofer Institute for Laser Technology ILT and Rapid Shape GmbH are working together to further develop resin-based 3D printing. The new “TwoCure” process requires no support structures and is significantly more efficient and productive than conventional 3D printing techniques for plastic components. Experts from Fraunhofer ILT will be presenting the state-funded joint development that makes use of the interaction of light and cold in forming the components at formnext 2017 from November 14 to 17 in Frankfurt am Main.
Much like stereolithography, one of the best-known processes for printing 3D plastic components works using photolithographic light exposure that causes liquid...
A team of researchers led by Prof. Wolfram Pernice from the Institute of Physics at Münster University has developed a miniature abacus on a microchip which calculates using light signals. With it they are paving the way to the development of new types of computer in which, as in the human brain, the computing and storage functions are combined in one element.
Researchers at the universities of Münster, Exeter and Oxford have developed a miniature “abacus” which can be used for calculating with light signals. With it...
Extremely short electron bunches are key to many new applications including ultrafast electron microscopy and table-top free-electron lasers. A german team of physicists from Rostock University, the Max Born Institute in Berlin, the Ludwig-Maxmilians-Universität Munich, and the Max Planck Institute of Quantum Optics in Garching has now shown how electrons can be accelerated in an extreme and well-controlled way with laser light, while crossing a silver particle of just a few nanometers.
Of particular importance for potential applications is the ability to manipulate the acceleration process, known as a swing-by maneuver from space travel, with...
Cancer cells can reactivate a cellular process that is an essential part of embryonic development. This allows them to leave the primary tumor, penetrate the surrounding tissue and form metastases in peripheral organs. In the journal Nature Communications, researchers from the University of Basel’s Department of Biomedicine provide an insight into the molecular networks that regulate this process.
During an embryo’s development, epithelial cells can break away from the cell cluster, modify their cell type-specific properties, and migrate into other...
