As more and more case-controlled facilities turn to CO₂ refrigeration, HVAC contractors are tasked with adequately educating themselves on these systems so that they can meet the country’s budding installation and service needs.

Food retailers are concerned over the HFC phasedown, noting that current alternative refrigerants have drawbacks, while others have not yet been fully evaluated.

Some food retailers express concerns over CO₂ refrigeration systems, which they have found to be leaky and less energy efficient than expected.

CO₂ systems’ environmental benefits and ability to meet any future regulations make them an optimal option for contractors and facility managers.

A pending global hydrofluorocarbon (HFC) phasedown and additional efficiency regulations have bolstered R-744’s position in the American food retail market, further accelerating interest in the refrigerant’s unique benefits.

EPA recently expanded its list of acceptable refrigerant substitutes for new refrigeration equipment to include R-471A and R-515B.

Suddenly in high demand, HVAC contractors must quickly acclimate themselves with CO₂ refrigeration and its unique characteristics and service attributes, which differ from traditional hydrofluorocarbon (HFC)-based systems.

CO₂ is a highly attractive refrigerant for contractors and end users because it boasts a global warming potential (GWP) of 1 and an ozone depletion potential (ODP) of zero.
