1/arbeitsgebiete/kaeltemaschinen-und-waermepumpen.html
7. L. Richter, M. Kuhn, M. Safarik, ILK Dresden, www.ilk.de have worked on chilled water
generation below 0 °C by a water-LiBr resorption cycle.
8. According to Peter Noeres (Fraunhofer UMSICHT), future R&D-perspectives are in the
further development of small units to get better values of COP, better performance; aircooled
absorber/condenser, chiller with integrated recooling system; size/cost reduction;
modification of the working pair to manage/avoid crystallization.
9. Report [9] by CHOSE for EU Directorate General for Energy (31/05/01) – Energy Savings
by CHCP plants in the Hotel Sector – Absorption Chillers, already mentioned above.
10. Research group belonging to the Department of Habitability, Energy and Environmental
Impact in Buildings of the Instituto de Ciencias de la Construcción Eduardo Torroja (CSIC)
located in Madrid, Spain. They are working on three research projects on air cooled LiBr
prototypes of small power and small size. The main results obtained are:
Two air cooled double effect prototypes: one gas fired (2006-2007) and the other one driven
by residual heat (2003-2006).
One air cooled single effect prototype designed using recooling (1996).
One Spanish patent (1999).
One International Patent in edition phase (2007).
1982-1985. Solar cooling systems constructed in the Solar Energy Experimental Plant of
CSIC in La Poveda, Arganda del Rey, Madrid.
1997-2004. Solar cooling system constructed in the Madrid Carlos III University
R&D themes
• Development of absorbers of small size able to work with outdoor temperatures of
around 40-42ºC.
• Simulation, design, construction and experimental evaluation of double effect lithium
bromide-water, air cooled prototypes of small cooling power (below 10 kW).
• Simulation, design, construction and experimental evaluation of single effect lithium
bromide-water, air cooled prototypes of small cooling power (below 10 kW).
• Air cooling lithium bromide systems driven by thermal solar energy.
11. Consortium for Alternative Cooling Technologies & Applications (ACTA), Center for
Environmental Energy Engineering, University of Maryland.
12. Christopher Kren, Technical University of Munich – list of publications (1998-2007)
indicates he is working on LiBr.
13. Powerpoint report by CSIRO Perspective on Renewable CHP & Absorption Refrigeration
Laboratory, Dr Dong Chen and Dr Stephen White, National Energy Transformed Flagship,
CSIRO, 14 May 2007, Renewable CHP. (ref:
www.sustainability.vic.gov.au/resources/documents/CSIRO_Solar_Cooling.pdf ).
14. Infante Ferreira, C.A. [C.A.InfanteFerreira@tudelft.nl], together with Dong-Seon Kim (now
Arsenal Research) have been exploiting the advantages of half-effect LiBr-H2O absorption
systems in combination with flat plate solar collectors to take advantage of the higher
efficiencies at lower heating medium temperatures.

research center. Part of its Energy Group collaborates intensively with Rotartica in its
products development. www.ikerlan.es. Latest innovations: The reliability of the systems
