R-32 is a next-generation, low-GWP refrigerant that efficiently carries heat in air conditioning systems. Daikin was the first to introduce air-conditioning and heat pump technology using R-32, starting in Japan in November 2012. Because of its lower GWP as well as energy efficiency and cost-effectiveness as compared to conventional refrigerants, R-32 has been safely deployed in over 190 million units globally* (Daikin's estimation).
The world has become more aware of the environmental impacts of refrigerants used in air conditioning, household appliances, and other applications. And that awareness has driven the industry to develop new refrigerants. Over the years, the industry has offered new technologies and solutions that are less impactful on the environment. Take a look of the evolution of refrigerants by mouseover the years below!
R-32 systems are up to 12% more efficient than similar R-410A systems.
R-32 refrigerant has a significantly lower total life cycle refrigerant impact on the environment compared to R-410A.
Over 190 million R-32 units have been safely deployed worldwide.
R-32 is a single-component refrigerant making it easier to clean, reuse, recover and reclaim than blends.
R-32 refrigerant's efficiency and capacity can allow for light weight units in certain applications.
R-32 is readily available from multiple suppliers.
R-32 refrigerant is easier to clean, reuse, recover and reclaim than non-azeotropic blends.
R-32 is endorsed by Daikin, Goodman, and Amana.
Learn MoreRefrigerant is a medium for conveying heat. Air conditioners transfer heat while circulating refrigerant between the indoor and outdoor units. Compared to the refrigerants widely used today such as R-22 and R-410A, R-32 has a global warming potential (GWP) that is one-third lower.
