A recent article on future HFC emissions addresses including HFCs within the Montreal Protocol scope, in order to preserve the climate benefit of the ODS (Ozone depletion Substances) phase-out.
Following an energy audit to improve the energy efficiency for the replacement of the existing HCFC-22 refrigeration system, a German chocolate producer has decided on an optimized HFC-134a based concept.
According to the recently released 2010 France refrigerants survey – published by Mines ParisTech/Armines/ERIE for the French ADEME Agency (Inventaires des Emissions des fluides frigorigènes - FRANCE – Année 2010) - the French total demand for refrigerants was 10,224 tonnes in 2010, of which 80 % HFCs (mainly HFC-134a and R-404A), 15 % HCFCs (practically only HFCF-22) and 5 % ammonia and CO2.
German installers have evaluated the use of R407C and of CO2 in air/water domestic heat pumps, and concluded that R407C gives a better environmental performance than CO2 - measured as TEWI (Total equivalent Warming Impact).
A newly installed Organic Rankine Cycle (ORC), using a mixture of HFC-134a and HFC-245fa as working fluid, will deliver an additional 2.5 MW to the existing 16.7 MW capacity of a Geothermal Facility in Nevada, USA.
COOL-SAVE is an Intelligent Energy – Europe project, designed to develop and disseminate cost effective strategies to improve energy efficiency in cooling systems in the food and drink sector, the biggest manufacturing sector in the UE.
