Closed adsorption storages have been investigated in several projects for heat storage in building applications with focus on energy density and performance. This study complements this research with the assessment of the environmental impacts over the life cycle. Global warming potential (GWP) was chosen as the assessment criterion. Selected sorpt...

The main objectives of research on innovative materials (phase change materials, PCM, or thermochemical materials, TCM) for thermal storage are the development of low-loss and compact storage systems with high capacity (sensible water storages being the benchmark). If the storage is to be implemented in an application with the aim to increase its e...

D-Mannitol is a potential phase change material to store thermal energy for process heat applications between 120 °C and 200 °C. This study presents thermal cycling stability tests of D-mannitol and its effect on melting enthalpy. Short-term cycling tests were carried out in differential scanning calorimeter in combination with air and nitrogen/vac...

The politically endorsed reduction of greenhouse gas emissions entails the transformation of thermal energy systems towards renewable energies, especially in the building sector. This comes along with a demand in energy storage, as there is a time offset between energy availability and demand. As sensible heat storages induce major losses and have...
Article
Thermal energy storage (TES) systems using phase change materials (PCM) are nowadays widely developed to be applied in solar power plants or cooling and domestic comfort services. The design of a TES system does not only rely on the energy density that a PCM can provide, but also on other important material properties such as its rheological behavi...

Full-text available
Die Energiewende ist bislang stark stromfokussiert, obwohl sie nur als Strom-, Wärme- und Mobilitätswende erfolgreich sein kann. Trotz großer Potenziale im Bereich Effizienz und erneuerbare Energien weist die Wärmewende in den letzten Jahren kaum Fortschritte auf. Im Jahr 2014 hatten die erneuerbaren Energien in Deutschland einen Anteil von 10,9 %...

To approach a market launch of small scale solar cooling installations, standardized and pre-designed packages offer a way for investment cost reduction and optimizing the control and operation strategies in a compressed way. In the German national research project “SolCoolSys”, six field test plants were installed and monitored under real conditio...
Book
Full-text available
The International Energy Agency (IEA) reports that 46% of global energy demand is devoted to heating and cooling. Two thirds of this demand is met by fossil fuels, either via electricity generation or direct combustion. Both the heating and cooling energy demands are expected to grow rapidly in the coming decades. In order to achieve the global goa...
Article
Thermal storage can make an important contribution towards tackling the rise in energy consumption by balancing energy supply with demand. In buildings Phase Change Materials (PCMs) are increasingly being used to reduce the heating and cooling peak demand. Phase Change Slurries (PCSs) are heat transfer fluids, which consist of a latent heat compone...
Article
Full-text available
Heat transformation based on adsorption/desorption of water in microporous adsorbents has been considered for the application as adsorption chiller (ACS), adsorption heat pump (AHP) or thermochemical storage (TCS) since the 1980s. Unfortunately, most of the available adsorbents like zeolites were not optimized for the use in these processes as they...
Technical Report

Vom 12.-14.11.2012 fand nun schon zum 7. Mal die auf die Initiative von Hermann Scheer gegründete International Renewable Energy Storage Conference (IRES) in Berlin statt. Eine erneut hohe Teilnehmerzahl von 600, davon rund ein Drittel aus dem internationalen Ausland, zeugen von dem Interesse und der Relevanz, die das Thema Energiespeicherung hat....
Conference Paper
The aim of this paper is to investigate if the procedure for adsorption equilibria measurements of meso-microporous solid adsorbent materials, already defined for standard adsorbents, is suitable for characterization of the new class of adsorbent materials MOFs (Metal-Organic Frameworks). Comparative measurements carried out at Fraunhofer-ISE and C...

Erhebliches Einsparpotential beim Verbrauch der fossilien Brennstoffe besteht in einer Erhö-hung der Effizienz thermischer Prozesse, einer verstärkten Abwärmenutzung industrieller Prozesswärme, dem vermehrtem Einsatz erneuerbarer Energie zur Wärmeerzeugung (bis-her etwa 4%) und in einem deutlichen Ausbau von KWK Anlagen. Die Verfügbarkeit einer eff...
Article
Thermally driven adsorption chillers and heat pumps are a very promising approach toward an efficient use of energy as well as an effective climate protection through reduced CO2 emission of conventional heating and cooling devices. With regard to current market entrance of this technology, this paper presents results on the stability of current av...
Conference Paper

In this work, a brief overview on current developments of and existing thermally driven heat pumps (TDHP) with focus on small scale systems (< 50 kW cooling) is given. First, a technical overview including a brief description of the different competing technologies like liquid absorption or solid adsorption systems is presented. Following informati...

In several demonstration and commercial projects new chilled ceilings with integrated PCM as dispersed latent heat storage were installed for high efficient low exergy cooling in buildings. Different combinations of ceilings and cold sources were realized to show the main advantages of using PCMs for each combination. The aim of the research projec...

Phase Change Slurries (PCS) are widely discussed as an alternative heat transfer fluid for cold storage and distribution systems. So far many publications were written dealing with microencapsulated phase change materials suspended in water to extend its heat capacity. Many of these publications are about research on these PCS more in a material po...
Article
The amount of heat that can be stored by common heat transfer fluids, e.g. water or oils, depends on the useable temperature range which can be exploited. The efficiency of such heat transfer fluids is poor if an application allows only a small temperature difference. One solution to increase the efficiency of such applications is to use phase-chan...
Article
The idea of improving the thermal comfort of lightweight buildings by integrating phase-change materials (PCMs) into the building structure has been investigated in various research projects over several decades. Most of these attempts applied macro-capsules or direct immersion processes, which both turned out to present several drawbacks. Due to t...

Planar air-breathing fuel cells in printed circuit board technology have been developed as a promising candidate for use in electronic devices. In order to analyze the operational behavior, a mathematical model of planar self-breathing fuel cells is developed and validated. Design guidelines are then derived from the modeling results. One of the ma...

Zusammenfassung A phase-change material (PCM) is characterised by a peak in its thermal capacity at an adjustable temperature. Integrated into a building wall or ceiling a phase-change material acts like a heat reservoir that reduces the room temperatures. This effect leads to reduced cooling loads in the summer or in the absence of an air conditio...

Wenn die klimatischen Bedingungen in einer Region permanent oder temporär von dem von den Nutzern als komfortabel empfundenen Bereich abweichen, muss das Innenraumklima durch entsprechende Maßnahmen so konditioniert werden, dass innerhalb des Gebäudes angenehme Verhältnisse herrschen. Die Aufgabe klimagerechten Bauens besteht darin, mit rein baulic...

The primary aim is to further increase the acceptance of heat pumps (as air-to-water, water-to-air, air-to-air and brine-to-water units ) for comfort purpose with respect to noise and vibration emissions. A second focus is placed on increasing knowledge at different levels (manufacturers, acoustic consultants, installers, legislators). For more details consult www.heatpumpingtechnologies.org/annex51
