2.10.1 Introduction
The Eduardo Torroja Institute for Construction Science, a Spanish National Research
Council (CSIC) body, is the sponsor of an "Energy Saving an Emissions Reduction in
Buildings” research group. In 2006 the group set out to build several prototypes of low-power
lithium bromide-water absorption chillers, capable of competing economically with
mechanical compression chillers, an endeavour funded by Spain's Ministry of Science and
Innovation under the INVISO (Industrialization of Sustainable Housing) sub-project
"Generación Sostenible de Energía en Viviendas" (sustainable energy generation in
housing). The first prototype was an air-cooled, direct-fired, double effect absorption chiller;
the second a solar powered single effect air-cooled absorption chiller and the third a
combination air-cooled, single-double-effect chiller, driven by solar power (or waste heat)
while operating as a single-effect apparatus or by burning fuel in double-effect mode.
The development of such prototypes was contingent upon designing, building and testing a
new generation absorber, smaller, more readily assembled and with higher mass and heat
transfer coefficients than in place to date. This absorber was developed between 2003 and
2006 under research projects DPI 2002-02439 and ENE 2005-08255-CO2-01 with funding
from Spain's Ministry of Industry. Once assembled and tested, the absorber was built into the
4.5kW; 7 kW and 10 kW power cooling prototypes.
