The United Nations Environment Programme (UNEP) Ozon Action Branch has published a booklet entitled ‘Low-GWP Alternatives in Commercial Refrigeration: Propane, CO2 and HFO Case Studies’ as part of UNEP’s work programme under the Climate and Clean Air Coalition (CCAC). The publication is the first in a series featuring case studies on alternatives to hydrofluorocarbons (HFCs), providing information on energy efficient, zero to low-GWP alternatives -intended to assist relevant decision makers, especially those in developing countries, in selecting the most appropriate climate-friendly alternatives. The studies cover a cross-section of low-GWP applications being adopted by supermarkets around the globe, from C02 transcritical and secondary cascade systems, and the adoption of low flammable refrigerant and HFO alternatives. They go on to cover the valuable lessons learned to enable a smooth transition away from high-GWP refrigerants and assist in selections of future refrigerants. The case studies include the type offacility, a background to the project, type of system, installation and refrigerant adopted, along with the challenges that were presented, system performance - advantages and disadvantages. Case studies included within this first publication include Carrefour SA Express, Kurtko?y, Turkey Transition from HFC R404A to a CO2 transcritical system Sobeys (IGA), Cookshirein, Quebec, Canada New CO2 transcritical system Verdemar, Nova Lima,Belo Horizonte, Brazil New CO2 cascade system using R-134a as primary circuit Waitrose, Bromley,Kent, United Kingdom HFO R-1234ze chiller plant system H-E-B, Mueller, Austin, Texas, United States Propane (R-290) self-contained integral case installation Low GWP Alternatives in commercial refrigeration _Propane CO2 and HFO Case studies [ΠΗΓΗ:http://www.fridgehub.com/] |
