Honeywell’s Low-Global-Warming-Potential Refrigerant Endorsed by SAE International Cooperative Research Project
SAE’s International Cooperative Research Program finds new refrigerant offers ‘superior environmental performance’
The SAE program team said refrigerant HFO-1234yf “offers superior environmental performance” and that “this alternative refrigerant — of all proposed alternatives — has been judged to have the lowest risk for use in mobile air conditioning systems in meeting environmental and consumer needs.”
The SAE’s research program was launched in 2007 as a response to the European Union’s MAC directive, which requires that all new vehicles produced starting in 2011 use a refrigerant with a global warming potential below 150. Current global mobile air conditioning systems use HFC-134a, a refrigerant with a GWP of 1,430. HFO-1234yf has a GWP of only four.
The SAE program’s extensive testing showed that HFO-1234yf is a “highly energy-efficient refrigerant, meaning autos with HFO-1234yf use less fuel and have fewer (greenhouse gas) emissions than those that use alternatives.” The program found that while CO2, another proposed alternative, has a global warming potential of 1, it “is less efficient than 1234yf, resulting in greater indirect emissions.”
The SAE program was conducted by international experts in the field of refrigerants and automotive technology from major automakers, as well as Tier 1 and 2 suppliers and independent test facilities. Program members include major automobile manufacturers from
Under the SAE program, the safety and effectiveness of air conditioning systems, performance, material compatibility and relative risks of HFO-1234yf were extensively evaluated.
“HFO-1234yf is a near drop-in replacement for current refrigerants, meaning it does not require a complete redesign of current air conditioning systems and can be more easily used in the existing fleet of automobiles,” said Mueller. “This means lower overall car costs for the consumer and faster adoption by automakers globally.”
