This system allows eliminating the cooling towers in those regions of the planet where water is scarce. This work analyses the environmental benefits of this air-cooled system, as well as its environmental foot-prints, compared to a solar water-cooled single effect. In this regard, a methodology has been applied to calculate the annual saving in water consumption produced in a case study: a hospital located in Almería, in South of Spain. Further-more, the reduction in energy consumption and CO2 emissions is also quantified since this machine can be driven by solar energy and with higher efficiency than those of single effect.eninfo:eu-repo/semantics/openAccessjournal articlesolar coolingair-cooledwater-energy nexuswater consumptiocarbon dioxide emissions reductionabsorption machinedouble effectenvironmental footprints
