Carbon Dioxide Refrigerant Monitoring
Carbon dioxide CO2 (R744) is a non-flammable, natural, low cost refrigerant with negligible direct global-warming impact and ozone-depletion potential compared to traditional hydrofluorocarbons (HFC). CO2 refrigerant has become more widely used in many applications, for example, in
- food and industrial processing
- cold storages
- food retail and transfer
- sports facilities, such as ice rinks
- car and residential air conditioning
To ensure safety of people in CO2 refrigerated facilities, CO2 levels must be monitored in places where potential refrigerant leaks can occur.
