The rollout and experience of natural refrigerants based technology at Carrefour

Refrigeration is a key concern for Carrefour and the company Executive Committee recognises the increasing contribution to total GHG emissions of HFCs and HCFCs. To take action on this issue Carrefour will begin phasing out these refrigerants by 2015 and replace them with HFC-free alternatives. The company has already reduced the volume of refrigerants used in the group, but aims to do more. Carrefour is testing 18 sites using natural refrigerants in France, Italy and Turkey, with two sites using 100% natural working fluids CO2 and ammonia. The company is now preparing to roll-out hybrid CO2/R134 installations.
