Guide 2013: Natural Refrigerants - Market Growth for North America

The new Guide 2013: Natural Refrigerants - Market Growth for North America gives an overview of the status of ammonia, CO2, hydrocarbons, water and air as refrigerants in various sectors (food chain, city & buildings, transport, and industry & special applications) in North America.
The new shecco Guide 2013: Natural Refrigerants - Market Growth for North America gives an overview of the status of ammonia, CO2, hydrocarbons, water and air as refrigerants in various sectors (food chain, city & buildings, transport, and industry & special applications) in North America.

For example, regarding the food chain, since the US EPA approved the use of CO2 in food retail refrigeration and cold storage warehouses in 2009, US food retailers have begun making significant investments in CO2 refrigeration. In Canada, transcritical CO2 is rapidly becoming an established commercial refrigeration technology.

Several large retail chains in North America are using ammonia cascade systems thanks to significant improvements in system design and better safety features.
Ammonia/CO2 cascade systems are believed to have a more stable performance than CO2 transcritical systems in warmer climates.
In the US, since hydrocarbons are not approved as an acceptable substitute for large retail food refrigeration by the EPA, their use is limited.
