Sonnenklima, Germany, make a small LiBr m/c (10kW) that operates with low temperature
heat (55 0 C). (ref: www.sonnenklima.de )
A report on Absorption Chillers (dated May 2001) prepared under the SAVE II Programme
called CHOSE, “Energy savings by CHCP plants in the Hotel Sector” includes a survey of
Lithium Bromide machines. The report includes a list of suppliers, as well as a short
discussion on single-effect machines, double-effect machines and small capacity low
temperate machines. (ref: www.inescc.pt/urepe/chose/reports/B-absorption_chillers.pdf).
The list includes many of the suppliers mentioned above as well as the following about which
no information was found on the internet:
LG Machinery, Korea
McQuay, USA
Mitsubishi, Japan
Toshiba, Japan
Kawasaki, Japan
Kyung Won, Korea
2.8 Research and Development – Water/Lithium Bromide Systems
This section lists organisations and individuals working in this field and projects relevant to
LiBr, as well as some comments that were received in the course of this work.
1.The Department of Engineering Science of Martin-Luther University of Halle-Wittenberg
have installed a 4.5 kW single-effect LiBr chiller with solar thermal collector.
2. Fundacion Cartif, Valladolid, Spain has been working on solar cooling since 1998, firstly
through an ERDF (European Regional Development Funds) project, by means of which a
solar air conditioning system was installed in its building and it has been kept working ever
since 1999. The system is composed of a 40 m 2 vacuum collector field (mounted on a solar
tracking platform), and a 37.5 m 2 flat collector field and a 35 kW absorption chiller for
conditioning the administration area (200 m 2 ).
3. ALONE Project, Small Scale Solar Cooling Device: University of Florence – CREAR (Italy,
Coordinator), EURAC Research (Italy), DLR (Germany), Solitem (Turkey), AOSOL
(Portugal), Ikerlan (Spain), Climatewell (Sweden) and Riello (Italy) are partners in a 7 th
Framework Projct ALONE, Small Scale Solar Cooling Device. The main aim of ALONE
project is to overcome the lack of small scale units, developing fully automated and
autonomous package-solutions for residential and small commercial or industrial solar
cooling applications based on systems able to cope with low temperature cooling
applications. Main efforts are on absorption chiller optimization for providing both heating and
cooling in solar systems: in fact, adaptation of components and control logic optimization is a
necessary step towards higher conversion performances and reduced costs. At four test
sites three different solar cooling technologies will be applied (Ammonia system, Lithium
bromide system, Lithium chloride system). The test sites are located in: Firenze
(Italy) NH3 with MT, Alentejo (Portugal) NH3 with LT, Vitoria-Gasteiz (Spain) LiBr, and
Bolzano (Italy) LiCl.
