refrigerants
Customers look to Carrier to develop sustainable solutions for refrigerants, especially given climate change considerations. For decades, the industry relied on chlorofluorocarbon (CFC) chemicals as refrigerants due to their energy efficiency, safety and economic benefits. In the 1970s and 1980s, scientists began to observe that CFCs contributed to the depletion of the Earth's stratospheric ozone layer that blocks harmful ultraviolet radiation from the sun. This led to an international accord to phase out ozone-depleting substances. Carrier did not wait for international mandates to move. We introduced the first commercial and residential air conditioning systems using non-ozone-depleting refrigerants in 1994 and have since led the industry away from ozone-depleting substances.
Carrier pioneered the phase-out of CFCs for the air conditioning and refrigeration industry in 1994, two years ahead of U.S. requirements and 16 years before mandates in developing countries.
For this achievement, the U.S. EPA awarded Carrier its "Best of the Best" Stratospheric Ozone Protection Award in 2007.
Today, Carrier continues to help international markets meet new non-ozone-depleting requirements, while focusing on the next chapter of refrigerant evolution to reduce the direct greenhouse gas effect. Many of today’s refrigerants are based on hydrofluorocarbon (HFC) chemicals because they do not deplete the ozone layer, and compared to CFCs, have reduced the greenhouse impact by as much as 80 percent. Nonetheless, HFCs remain a greenhouse gas and Carrier is committed to finding lower global-warming alternatives. We are a leader in providing commercial refrigeration systems for supermarkets using ultra-low global-warming carbon dioxide as a natural refrigerant, which is captured in the air and repurposed for cooling.
Carrier continuously invests in research and development. As we have done before, Carrier is committed to deploying products and technologies that minimize environmental impact while serving customer needs. This is equally true with refrigerants, where Carrier will have the right refrigerant solution for every application, while not every application may have the same refrigerant solution.
NaturaLINE™
In 2010, Carrier introduced the world’s first natural refrigerant technology for container refrigeration. NaturaLINE™, Carrier’s newest container refrigeration unit will feature breakthrough technology, using carbon dioxide as a natural refrigerant.
