) is used as the baseline against which all other gases are measured. (CO

= 1.0 GWP — HFC134A = 1,300.0 GWP). In other words, releasing 1 pound of RA is equal to emitting into our atmosphere 1,300 pounds of CO

can be used as a refrigerant. Its refrigerant nomenclature (name) is RR systems are in development and are expected to enter the original equipment market in the near future. CO systems are more fuel‐efficient and can increase cooling performance as compared to RA systems. CO systems operate at 7 to 10 times the pressure of systems containing RA. Due to the very high pressures associated with R EPA has established
