The vision of BIOCOOLING, Bio-based solvents for the technological development of novel wet compression\/absorption CO2<\/sub><\/em> refrigeration systems, is the integration of mixtures of CO2<\/sub> with biomass-based solvents (BBS) as working fluids for wet compression\/absorption refrigeration (WCA) machines with advanced measurements and novel modeling.<\/p>\n\n\n\n

Recent reports from the International Institute of Refrigeration (IIR) estimate that 8% of global greenhouse gas (GHG) emissions are attributed to refrigeration, air conditioning and heat pumps. Of these, 60% are indirect emissions associated with the manufacture of the more than 3 billion refrigeration units operating worldwide and the production of electricity to operate them (17% of global electricity consumption), and 40% are direct emissions from the refrigerant itself that is unintentionally released during maintenance, decommissioning or through leaks. Our vision is needed to meet the challenges posed by alternative, clean refrigeration fluids and systems that address climate change and tackle global warming. To this end, this project embarks on the development of a new series of very low-polluting refrigerants for energy-efficient refrigeration cycles.<\/p>\n\n\n\n

The starting hypothesis of BIOCOOLING is that a thorough thermodynamic characterization and modeling of CO2<\/sub> mixtures with different BBS will lead to the development of safer, greener and more efficient refrigeration systems. The overall objectives are:<\/p>\n\n\n\n
