Refrigerants

GreenChill is an EPA partnership with food retailers to reduce refrigerant emissions and decrease their impact on the ozone layer and climate change. The 2010 phaseout of certain hydrochlorofluorocarbons (HCFCs) – particularly HCFC-22 – under the Clean Air Act marked a major step in the transition to alternative refrigerants. The majority of supermarkets use HCFC-22 as their primary refrigerant and while it remains legal to run an installed HCFC-22 system, refrigerant production for servicing HCFC-22 equipment ended in 2020. Additionally, high rates of refrigerant leaks are common. GreenChill assists food retailers take advantage of improved technologies for supermarket refrigerants to reduce leaks and provides food retailers with ozone and climate-friendly alternatives that align with the new regulatory framework.
