ShareAn innovative NH3/CO2 cascade system in the US
By deploying a NH3/CO2 cascade system, a supermarket in Columbus, Georgia, reduced its annual direct emissions by at least 95%
According to the EPA, a typical US supermarket has an annual leakage rate of 453.6 kg of harmful refrigerant into the atmosphere.
By deploying a NH3/CO2 cascade system, a Piggly Wiggly supermarket in Columbus, Georgia, achieved the EPA’s highest GreenChill platinum status by reducing its annual direct emissions by at least 95% and its global warming impact to only 1% of a traditional store using HFC refrigerants.
The innovative design of this system reduced the ammonia charge to only 0.1 kg/kW totaling 24 kg, all of which is confined to the supermarket roof.
