Move to HFC-410A in refrigeration applications.

Author(s) : RIVET P.

Summary

As they are more environmentally friendly, compared to HCFCs and HFCs, natural refrigerants are being in refrigeration plants. But CO2, HCs and NH3 have limitations due to some of their characteristics, respectively, working pressure, flammability and toxicity. In countries like Europe, where HCFCs are banned in new plants, HFCs are widely used in small and medium refrigeration plants(food industries and retail sectors). They have zero ODP, are sufficiently energy-efficient from -40 to 0°C and plant investment, as well as running costs, are competitive. However, their GWPs are high, but today, refrigerant charges and containment have been improved. In refrigeration applications, food production, storage, distribution, retail, HFC R-404A is mainly used for high-temperature (-10 to -15°C) and low-temperature (-30 to -40°C) applications. R-134a is used today in car air conditioning (but will be restricted by 2011) and in large and medium water chillers, while R-410A is used in small AC packages, and since two years ago in small and medium water chillers, replacing R-407C and R-404A. This paper considers the value of replacing R-404A by R-410A in refrigeration fields, in terms of direct and indirect greenhouse impacts, today's possibilities, investment and running costs.
